The format of a research paper hasn’t changed much throughout history, despite the enormous changes in platforms available for their consumption and the near extinction of the library issue. Convenient electronic files such as PDFs still resemble printed-and-bound-in-issues papers in their layout instead of exploiting the seemingly endless capabilities of the electronic format.
For instance, why do we still need to have page numbers? a DOI is a full, traceable and unique identification for each work and there are so many nowadays that publishers have to pour them out as e-first, ASAPs, and just accepted before having them assigned page numbers, a process which is still a concern for some researchers (and even for some of the organizations funding them or evaluating their performance). Numbers for Issues, Volumes and Pages are library indexes needed to sort and retrieve information from physical journals but in the e-realm where one can browse all issues online, perform a search and download the results these indexes are hardly of any use, only the year is helpful in establishing a chronological order to the development of ideas. This brings me to the next issue (no pun intended): If bound-issues are no longer a thing then neither should be covers. Being selected for a cover is a huge honor, it means the editorial staff think your work stands out from the published works in the same period; but nowadays is an honor that comes to a price, sometimes a high price. With the existence of covers, back-covers, inner-covers and inner-back-covers and whatnot at USD$1,500 a piece, the honor gets a bit diluted. Advertisers know this and now they place their ads as banners, pop-ups and other online digital formats instead of -to some extent- paying for placing ads in the pages of the journals.
I recently posted a quick informal poll on Twitter about the scientific reading habits of chemists and I confirmed what I expected: only one in five still prefers to mostly read papers on actual paper*, the rest rely on an electronic version such as HTML full text or the most popular PDF on a suitable reader.

What came as a surprise for me was that in the follow up poll, Reference Manager programs such as Mendeley, Zotero, EndNote or ReadCube are only preferred by 15% while 80% prefer the PDF reader (I’m guessing Acrobat Reader might be the most popular.) A minority seems to prefer the HTML full text version, which I think is the richest but hardly customizable for note taking, sharing, or, uhm hoarding.
A follow up on the previous poll. Dear #ChemTweeps, if you mostly read papers in electronic format what is your preferred platform?
— Joaquin Barroso (@joaquinbarroso) June 10, 2019
I’m a Mendeley user because I like the integration between users, its portability between platforms and the synchronization features but if I were to move to another reference manager software it would be ReadCube. I like taking notes, highlighting text, and adding summaries and ideas onto the file but above all I like the fact that I can conduct searches in the myriad of PDF files I’ve acumulated over the years. During my PhD studies I had piles of (physical) paper and folders with PDF files that sometimes were easier to print than to sort and organize (I even had a spreadsheet with the literature read-a nightmarish project in itself!)
So, here is my wish list for what I want e-papers in the 21st century to do. Some features are somewhat available in some journals and some can be achieved within the PDF itself others would require a new format or a new platform to be carried out. Please comment what other features would you like to have in papers.
- Say goodbye to the two columns format. I’m zooming to a single column anyway.
- Pop-up charts/plots/schemes/figures. Let me take a look at any graphical object by hovering (or 3D touching in iOS, whatever) on the “see Figure X” legend instead of having to move back and forth to check it, specially when the legend is “see figure SX” and I have to go to the Supporting Information file/section.
- Pop-up References. Currently some PDFs let you jump to the References section when you click on one but you can’t jump back but scroll and find the point where you left.
- Interactive objects. Structures, whether from X-ray diffraction experiments or calculations could be deposited as raw coordinates files for people to play with and most importantly to download** and work with. This would increase the hosting journals need to devote to each work so I’m not holding my breath.
- Audio output. This one should be trickier, but far most helpful. I commute long hours so having papers being read out loud would be a huge time-saver, but it has to be smart. Currently I make Siri read papers by opening them in the Mendeley app, then “select all“, “voice“, but when it hits a formula, or a set of equations the flow is lost (instead of reading water as ‘H-Two-O‘, it reads ‘H-subscript Two-O‘; try having the formula of a perovskite be read)
- A compiler that outputs the ‘traditional version‘ for printing. Sure, why not.
I realize this post may come out as shallow in view of the Plan-S or FAIR initiatives, sorry for that but comfort is not incompatible with accessibility.
What other features do you think research papers should have by now?
* It is true that our attention -and more importantly- our retention of information is not the same when we read on paper than on a screen. Recently there was an interview on this matter on Science Friday.
** I absolutely hate having a Supporting Information section with long PDF lists of coordinates to copy-paste and fix into a new input file. OpenBabel, people!
The video below is a sad recount of the scientific conditions in Mexico that have driven an enormous amount of brain power to other countries. Doing science is always a hard endeavour but in developing countries is also filled with so many hurdles that it makes you wonder if it is all worth the constant frustration.
That is why I think it is even more important for the Latin American community to make our science visible, and special issues like this one from the International Journal of Quantum Chemistry goes a long way in doing so. This is not the first time IJQC devotes a special issue to the Comp.Chem. done south of the proverbial border, a full issue devoted to the Mexican Physical Chemistry Meetings (RMFQT) was also published six years ago.
I believe these special issues in mainstream journals are great ways of promoting our work in a collected way that stresses our particular lines of research instead of having them spread a number of journals. Also, and I may be ostracized for this, but I think coming up with a new journal for a specific geographical community represents a lot of effort that takes an enormous amount of time to take off and thus gain visibility.
For these reasons I’ve been cooking up some ideas for the next RMFQT website. I don’t pretend to say that my colleagues need any shoutouts from my part -I could only be so lucky to produce such fine pieces of research myself- but it wouldn’t hurt to have a more established online presence as a community.
¡Viva la ciencia Latinoamericana!
This initiative has turned out to be a lot of fun for me! I think so far the thing that has captured my attention the most is to grasp the realization that science, chemistry in this case, is performed by humans in small, and sometimes not so confident, steps, a description far from the pristine one we daily read throughout the plethora of journals. A similar former initiative, which should have been brought back during this week, was the #OverlyHonestMethods one. It’d be a lot of fun to have both hastags together during an entire week. The other thing I knew, but that #RealTimeChem has helped me understand is the fact that a lot of resources for research are needed and getting said resources consumes a lot of our time as researchers: grant submissions; applications revisions; meetings; academic events and a long etcetera occupy our time and attention and this isn’t necessarily a good thing all the time.
So here it is; my second day reporting my #RealTimeChem
Supporting information for our paper feels endless now. I want to launch calculations & I still have a ton of emails to reply!
Supporting information for our most recent paper consists of more than 200 figures corresponding to a few conformations from several compounds; this has consumed a lot of my time but I’m finally done with it! Now, its only a matter of time for us to submit it -we are aiming high!- and hopefully this may happen during #RealTimeChem. That would be cool!
No reply, unfortunately. I need to run some calculations for a small collaboration and these compounds include either La or Pr; I need a, preferably relativistic or quasirelativistic) effective core potential (maybe I should write a post illustrating the difference between ECP’s and pseudopotentials) for these atoms that is also compatible with some relatively simple electron density functional. The Basis Set Exchange library has one by Cao but its not referenced so there is only so much I can do with it.
Watching all the wheels of chemistry turn (slowly) during
#RealTimeChem makes you realize why each paper represents years of hard work
Between reading a Tweet about a grant submission and another one about having a paper published there is a lot of time and hard work involved, not to mention frustration, a little procrastination and a lot of fun over the course of a few years. During those years some chromatography columns are performed, some flasks are smashed and spectra are recorded. And this all happens very, very slowly as opposed as how we read it in journals where people seem to have had an original idea, gone to their labs, set up a few experiments, recorded the results and written the paper, and all before dinner!
The hindrances and intricacies of chemistry now have an outlet: blog-syn.blogspot.com In this site, the little details about synthesis are gathered in a sort of #OverlyHonestMethods way, only not as embarrassing; only practical. In a way, blog-syn is what this blog of mine was supposed to be for the lab of Dr. Silaghi-Dumitrescu back in Romania when I first conceived it. Little by little, the wheels of science turn but with every turn they move mankind forward.
Sadly, Maru is about to leave us for a short period of time now that she has completed her thesis and is about to get her B. Sc. in Chemistry; she threatens to come back for a Masters degree, though. She has played a crucial role in the lab’s success so I thought of taking a picture of her while working on her workstation. @RealTimeChem, the official Twitter account of the event, favorited this photo.
Tuesdays I teach a class titled ‘Molecular Design and Reactivity‘ (terrible name, I know) and today’s topic was the Valence-Bond method which, I’m sure you all know, is only of historical relevance although some nice conceptions arise from it, like the fact that a wavefunction can be approximated as a linear combination of smaller wavefunctions each corresponding to a specific electron configuration. I mostly use Donald McQuarrie‘s book on Quantum Chemistry, in case you are wondering.
This is a long three hours class starting at 5pm, and the research center is far from the chemistry school, so I usually don’t go back to the office afterwards. So here I am, at Starbucks in downtown Toluca, but chemistry for today is far from over! I still need to review some applications from students who are seeking funds from the local council for science to attend a seminar on polymers this summer in Barcelona. I was also requested by the Journal of Inclusion Phenomena and Macrocyclic Chemistry to serve as a reviewer for a submitted paper. Both activities have deadlines in May but I want to get them done now so I can
brag include them in my #RealTimeChem productivity report.
A few hours later…
Just Finished reading two proposals, I’m going to accept them both! 2 kids going 2 intl polymer seminar
And so I did it! Two students from a private university in the state want to participate in a polymer seminar in Spain. I think they have impressive results; too bad I had to sign a disclosure agreement so I can’t write anything about their project. Good for them and good for COMECyT for sponsoring outstanding students in science and engineering!
These past two days I haven’t personally launched any calculations; I haven’t had time to read any journals nor to write any applications or papers, yet I’m certain that the wheels at our lab are slowly turning, hopefully forward.
If a mind is a terrible thing to waste, then wasting a collective mind is an even more terrible thing. During the past weekend the library at the institute of chemistry suffered a flood caused by a broken pipe just above it, which incidentally happens to be the lab were I used to work as an undergrad student. When it comes to scientific journals, our institute still relies a lot on paper issues for the oldest numbers; we can order them online but it’s just easier to Xerox it at the library if you really need to read that old reference.
This morning the librarians were appalled when noticed not only the huge puddle on the floor but all the books and scientific journals that were dripping water from the shelves. The broken pipe has been fixed and the water on the floor has been mopped. It is now the books the ones that suffer the aftermath of this accident. Not only saving the information was important; wet paper is a great culture media for fungi which in turn could pose a health threat to all users. The administrative staff immediately got to work in recruiting academics and students to help the drying process: “Heal a book!“, they informally called it. Everyone grabbed an item and with the help of industrial blow dryers – the kind we use in chemistry labs to dry wet glassware – and an extraordinary amount of paper towels, each person got to dry the journals page by page.
I got an item that corresponded to the British journal New Scientist, which consisted of about fifteen issues from the year 1980. When I noticed the title in my hand I wanted to switch it. Should we save first those journals with the highest impact factor? or should we work on those that are most relevant to our own research? Should we throw away Chemical Abstracts now that the whole database is online? After all, New Scientist is a magazine which summarizes research that has already been peer reviewed and published; it is journalistic work, not peer reviewed science. But I was afraid to look pedantic so I got to work on drying it.
Each person had their own technique. Some journals had their binding covers still in good shape so they were placed open standing on the floor in front of fans. Some placed paper towels carefully between pages and after a while they would remove them and then use the blow dryer. I thought that if I heated the edges of the paper and thus dried them, capillarity would drive the moisture in the innermost part of each page outwards. Didn’t quite work, at least not in a pragmatic time scale, so I went back to page by page.
I’m glad I did so. That way I was able to find some real pieces of history which could make any scientist nostalgic. For example: I took these photos with my iPod, and if you are by any chance reading this piece on an iPhone, you must find the following picture about Swedish research endearing.
Yes, online doodling games were already a thought back in 1980!
Are you subscribed to this blog? That means you got a notification by e-mail. So what? No big deal! Well, back in 1980 Britain was getting excited over a new form of comunication called the ‘Electronic Mail’ (available only at a couple of post offices). Besides, you wouldn’t have been able to get that message nor read this post on an HP Matrix Machine (you can’t even find a decent link in google about it nowadays!)
But scientists are not all about working, we like games too! So how about purchasing a ‘Hungarian Magic Cube‘ or a ‘Chess Computer‘?
We also love a juicy piece of gossip. For instance, did you know that John Maddox was a controversial editor for Nature back in the 70’s who, as a student, went into chemistry because if he’d gone into physics he could’ve been drafted by the army in WWII to work on radars? Well me neither. But it seems that we should have known who he was, and now we do.
There were many pieces of science news that nearly kept me in the library all night, if not for the fact that I had to drive 50 miles from Mexico City to my place in Toluca, but the one that captured my attention more than any other was the news of a European dream envisioned more than three decades ago; a dream from a group of scientists about looking for answers, like any other group of scientists, answers that are fundamental for the understanding of our universe and the understanding of matter, back when some of the biggest questions hadn’t even been fully posed, this group of visionaries agreed on taking the necessary steps to build an enormous subatomic-particle Supercollider for the European Center for Nuclear Research, better known as CERN.
Back in 1980 I was already alive but I was only two years old. I could barely talk and had no idea what the word ‘future‘ meant, let alone what I’d become when it reached me. Now, even if I’m not a particle physicist I get excited about the news regarding the finding of the Higgs Boson and even if I’m not an astronomer I also get excited about pictures from the Curiosity Rover on Mars. I am a scientist. One out of hundreds of thousands or perhaps even millions, and this is part of my collective memory, the memory of the work of those who paved the road for us, those giants upon whose shoulders we struggle day by day to stand with dignity and against all odds. But here is the thing: those giants are actually made of dwarfs, millions of them; millions of us. Thousands and thousands of papers written, reviewed and published; papers that collectively gather the scientific experience summed up in rigorous experiments both successful and failed.
Preserving the information in those wet journals is important despite the fact you can get them all online. I hope one day a bored chemistry grad student goes to the library and browses old issues of New Scientist and other journals just for fun; they’ll go for a trip down a collective Memory Lane which will remind them that if they can dream it in the present, they can make it come true in the future.
A new paper has been published and that is always good news. The paper entitled “Synthesis of new γ-lactones from preactivated monosubstituted pyrazines and TMS–ketene acetals” coauthored by Azucena Garduño-Alva, M. Carmen Ortega-Alfaro, José G. López-Cortés, Isabel Chávez, Joaquin Barroso-Flores, Rubén A. Toscano, Henri Rudler and Cecilio Álvarez-Toledano was a fruitful collaboration between several researchers from within the UNAM Institute of Chemistry and from other labs.
Therein, the lactone formation from pyrazines is analyzed, with some resulting orientations not quite in accordance with the common orientation patterns yield by electrondonor and electronwithrdawing groups. In order to assess the electronic structure of the intermediates and its influence on the resulting orientations, I performed a Fukui analysis based on the Natural Population formalism.

We recently got notice of our paper being accepted for publication in the Journal of Inclusion Phenomena and Macrocyclic Chemistry. We are very pleased with this news! The paper’s title is “Ab initio calculations of electronic interactions in inclusion complexes of calix- and thiacalix[n]arenes and block s cations” and is being co-authored by Dr. Petronela Petrar, Prof. Dr. Kunsagi-Mate Sandor, the late Prof. Dr. Ioan Silaghi-Dumitrescu and yours truly. Most of the work reported in this article was performed at the Faculty of Chemistry of the Babeş-Bolyai University in Romania and also at Pécsi Tudomanyegyetem in Hungary (one lovely summer that was!)
In this paper we address the calculations of the cavity of a small family of calixarenes and explore the electrostatic interactions present when some s block cations are inserted within. Two main factors affect the stability of the complexes: Fitting. The ratio between the cation radius and the mean size of the cavity; The second factor is the ionic-π interactions with the aromatic rings that make the cavity.
As usual the paper is available in pdf format at your request from this author.

This title may sound like the one of an episode of the famous geeky sitcom The Big Bang Theory but it is not; it is in fact a far more interesting albeit less fun debate. First of all I want to make clear this post isn’t an attempt to further bash Dr. Schön err I mean Mr. Schön (sorry, I couldn’t help it) but the entire debate raises some interesting questions, specially those regarding the recent outcome of the controversy as well as the forthcoming aftermath, that are worth asking and of course, with some luck, answering.
A little background first: Jan Hendrik Schön (Germany, 1970) got a PhD in physics at the prestigious Konstanz University in his homeland; after that he got a job as a researcher at the even more prestigious Bell Laboratories located in New Jersey USA, where he made groundbreaking discoveries on conductivity, superconductivity, organic conductors and semiconductors. Ironically enough, his conduct was his doom (Sorry again, I couldn’t help this one either. ) Between 2001 and 2002 he published more than 60 scientific papers on these topics, 15 or so of which were published in Science and Nature. Similarities in the graphs led to other scientists to believe the data could have been manipulated which turned out to be the case! Little by little, both journals Science and Nature, as well as other important journals like Physical Review and Applied Physics Letters withdrew some of his papers; others remain under further investigation for their possible withdrawal. Dr. Jan Schön eventually had to come clean and confess his lack of scientific rigor and misbehavior. This and him being fired from Bell Labs could have been the end of the story but in no way was near it. In 2004 the University of Konstanz decided to withdraw his PhD degree to which Dr. Schön appealed on the grounds that his thesis work was performed without any data manipulation or any other sort of ethical misconduct on his part; finally today after seven years of back and forth lawsuits and appeals the state court ruled against him and the university stripped him from his degree. Dr. Schön is now Mr. Schön. Further details (since this post does not intend to be a repository of others nor to just inform you about the entire gossip) can be found in this Wikipedia article.
So what is this post about then? First of all I’d like to address the obvious questions: Was the University of Konstanz right or wrong about withdrawing his degree? Did they go too far? What are the implications for other scientists? There is still controversy among the scientific community about whether or not the University had any right to do it on the grounds of scientific misconduct on work that they did not fund nor had to do anything with. The matter is fairly obvious, the University of Konstanz does not want to be affiliated with Schön on any level since it will indirectly hurt their reputation. But is someone really thinking that this university is to blame? I hardly think so. Therefore on that side they could have let him keep his degree but on the other side one may postulate that credibility must be sustained throughout our careers just in the same way as MD’s can have their licenses revoked under malpractice. Granted, MD’s get stripped only from the right to legally exercise medicine not from their degree, meaning that in some cases they may recover that legal right instead of having to go to school all over again, although in the harshest cases this wouldn’t help either.
Definitely his conduct deserved strong actions from his employers and the scientific community, in the end almost 30 papers in very prestigious journals had to be withdrawn! He was trying to take the scientific community for a spin! And this is another thing I’m baffled about. Didn’t he ever think that such claims, such amazing claims, would attract the interest of a large number of the most prominent scientists working in the field of conductivity? As if there weren’t billions of dollars invested in those topics worldwide! If he was breaking new ground in organic superconductivity by proving some theoretical predictions, he would have gotten a Nobel prize for sure and that would have attracted a lot more people in trying to reproduce his findings in order to make their own little contributions therefrom. In fact this actually happened! Many laboratories throughout the world claimed to have failed in reproducing his results. I can only imagine those teams feeling frustrated for not being able to get the same numbers/trends in their experiments and clearly getting less and less frustrated when they found out they were not alone and that the number of their companions was growing larger. Had he published his results in some obscure, dubious-quality journal probably nobody would have ever found out, but then Lucent Technologies, the profitable company that runs Bell Labs would have not been happy in funding his research. This in turn raises yet other questions: How come nobody at Bell Labs was able to tell his results were all made up or even just tempered with? Private companies are not run as academic labs, publication of findings go through a lengthier process than in academia, which is normal since private research centers invest a lot of money in developing technologies which will generate enough profit to keep the company running and researching for as long as possible. They also have strict policies about data-recording and experiment-tracking procedures which apply to every researcher in the company; they are not subject to interpretation or to desire, they have to be followed to keep track of all the expensive research done within. The second question I got from this paragraph is about other frauds done in lesser journals which may go unnoticed because the work itself simply goes unnoticed by its own lack of merit. And from this, yet another question is raised and linked to another ongoing controversy: What is the future of peer-reviewing in journal publications? Surely no referee would have tried to reproduce his experiments and I’m sure a large number of data was requested by Nature and Science in order to deem the papers worth of being published (was his answer to this request “No problem!“?) Referees this quality were blindsided by reputations, Schön’s and Bell Lab’s; only until the final users (the readers) noticed similarities between data sets, and noise, in different experiments that the fraud rose to the surface, but noticing those similarities should have been the work of the referees! in fact that is their job! Aren’t they accountable by omission too?
This controversy is not a first, nor will it be the last. The most famous controversy of data tempering that comes to mind right now is the infamous experiment, or more accurately the infamous data selection in Robert Millikan’s experiment for measuring the charge of the electron. In this experiment only the “nicest” data points were used and although inclusion of the entire data set would have not affected the final value of the charge obtained, the statistical error would be increased to 2% instead of 0.5% as he presented it to the scientific community; a much “nicer” error. Of course I’m not trying to compare both cases which are completely apart; selecting data is not as serious as data manufacturing, but they are both just as unethical. Should have Millikan been stripped from his PhD degree and/or his Nobel Prize?
Mexico is not immune to this controversies either. In 2006 three papers authored by the famous Mexican Professor Eusebio Juaristi and his student Omar Muñoz-Muñiz in 2003, had to be withdrawn also on the grounds of irreproducibility from the Journal of Organic Chemistry, Tetrahedron and Tetrahedron Letters. There were serious errors in those papers which led to believe the student had incurred in scientific misconduct but apparently they managed to prove they were simply honest mistakes. Was Muñoz-Muñiz denied his PhD degree? No. In fact he now works as a researcher at Universidad Veracruzana in Mexico. Not a bad gig. I understand he had some problems getting into the National Researchers System which gathers us all researchers in Mexico as an independent entity at the same time that it collects data about the research done in the country. Data seems to be today’s secret word kids! Once again the whole ordeal could have been dealt with if a proper peer reviewing process had been carried out from the very start.
