7:44 AM | The Web - What is the issue?
From Wikipedia.Last week I gave an invited presentation in the nice library of the Royal Society of Chemistry, at the What's in a Name? The Unsung Heroes of Open Innovation: Nomenclature and Terminology meeting. I was asked to speak about HTML in this context, something I have worked with as channel for communication of scientific knowledge and data for almost 20 years know. Mostly in the area of small molecules, starting with the Dictionary of Organic Chemistry, which is interesting […]

7:36 AM | The history of the Woordenboek Organische Chemie
Chemistry students at the Radboud University in Nijmegen (then called the Catholic University of Nijmegen) got internet access in spring 1994. BTW, the catholic part only was reflected in the curriculum in that philosophy was an obligatory course. The internet access part meant a few things:xblastHTML and web serversemailOur university also had a campus-wide IT group that experimented with new technologies. So, many students had internet access via cable early on (though I do not remember when […]

7:39 PM | I want to ride my bicycle. I want to ride it where I like.
This article titled “Do cycle lanes increase safety of cyclists from overtaking vehicles?” popped on up on chemistry news feed recently. I couldn’t understand where the chemistry came into that question (are new bike lanes being made from some novel material? does it have something to do with the material of tires? was this some kind of […]

3:37 PM | Job posting: Senior Scientist II, AbbVie, Lake Forest, IL
Via Crash, I think it is interesting how specific some of these process positions are getting these days: AbbVie is seeking a creative and highly motivated chemist to work in its Catalysis Group to conduct research and development of state-of-the-art catalytic methods (e.g., C-H activation, C-X cross coupling, asymmetric hydrogenation, organocatalysis, photoredox catalysis, etc.) for applications spanning the continuum of pharmaceutical discovery through development and commercialization […]

3:27 PM | Anyone know the answer to this question on SDS format?
What do resellers or distributors of chemicals need to do, with respect to safety data sheets? Are there any rules (GHS or other) that say the SDS has to come from the company that physically made the solution? Do safety data sheets need to include the reseller/distributor's company information on the sheet, the actual manufacturer that makes the chemicals, and/or both? Answers accepted by e-mail or in the comments - thanks!

2:49 PM | UK labor law is different, apparently
An interesting forward from an anonymous source in the UK: Male Laboratory Technicians, £17,000, Permanent, Guildford I am looking to fill two lab vacancies for a local pharmaceutical company. The company specialises in research and development and is going through a period of growth. This is a great opportunity to begin a scientific career.... ...These positions are only open to male applicants, this is due to the exposure of teratogenic drugs which women should not use.I […]

2:31 PM | A public recording of a bet with Rob Westervelt, editor of IHS Chemical Week
A couple weeks ago, I expressed my frustration on Twitter with a USA Today piece that seemed to be an attempt to push younger people into manufacturing careers without a recognition that, over the long term, employment in manufacturing has been falling:"Anyone touting new blue-collar jobs be willing to put $500 down on 10 year trajectory of manufacturing employment?"Rob Westervelt (the editor-in-chief of IHS Chemical Week) asked what the over/under for growth in the manufacturing super-sector […]

1:46 PM | Adopt-a-Book
Old books need help. Left to their own devices, they fall apart, get moldy, and decompose.  CHF recently launched an Adopt-a-Book program which asks donors to “adopt” one of the Othmer Library’s many books in need of preservation, essentially paying for their medical care. One side benefit of this program is that images of these beautiful tomes are now available online. Anyone can look at the covers and at some of the pages of these old texts, including some alchemical […]

1:35 PM | What is a Compound?
A chemical compound is defined as a chemical substance with two or more different elements that can be separated by various methods. It’s important to note that pure chemical elements in forms that contain more than one atom – such as H2 or S8 – are not considered compounds. In this case, these are called [...]

8:18 AM | A nanoparticle-based alternative to Viagra
The majority of men who undergo radical prostatectomy for the treatment of prostate cancer will suffer from erectile dysfunction due to disruption of the cavernous nerve. This nerve has been identified as responsible for penile erection. The oral erectogenic PDE5 inhibitors like Viagra rely on the functioning of this nerve to provide the initial burst of nitric oxide necessary to initiate an erection. In this condition nanotechnology - in the form of a nanoparticle delivery system - may come to […]

4:16 AM | Publication of the week, number 48, 24th October 2014
This week’s pick involves a reagent that one does not often see used in organic synthesis, which is laughable really, considering it’s potential: nitrous oxide. It was reported here by a group from the ETH Lausanne led by Prof. Severin. The chemistry leads to the synthesis of triazenes which may have a use as cytotoxic […]

3:16 AM | Quick Thought for the Night
The Society of Forensic Toxicologists (SOFT) annual conference is wrapping up tomorrow. I'll be glad to get home to my family, bed, and shower, but I cannot express how grateful I am to hold membership in a wonderful organization. SOFT is quite a bit of fun, but it is always a tremendous learning experience.  Here's to 2015 in Atlanta.

3:40 PM | Mole Day – Avogadro & The Mole
Today, 23rd October, is Mole Day – which might put you in mind of small, furry, burrowing animals. However, they don’t even seem to have a commemorative day of any kind; we’re actually talking about the mole in chemistry, a quantity that essentially allows us to ‘count’ atoms and molecules in a more convenient way.

2:05 PM | Researchers break nano barrier to engineer the first protein microfiber
Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale - a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.

1:57 PM | Who put the "plastic" in plastic surgery?
"Plastic Surgery" is the hot topic of the day (especially as it relates to Renee Zellweger) and so the question arises as to what plastic is used in plastic surgery. The word "plastic" is an old word that is used in many diverse settings. In materials science, there is plastic deformation. You also have the macromolecules that are the subject of most of the posts on this blog and you have the surgery. It may be surprising, but these uses are all based on the same meaning that the word "plastic" […]

1:56 PM | I find this NYT article just a bit naive
Surely we don't need professors to tell us about hiding information from your colleagues at work: Knowledge-hiding in the workplace is common and takes different forms, some more harmful than others, according to new research by Catherine E. Connelly, an associate business professor at McMaster University in Hamilton, Ontario, and David Zweig, an associate management professor at the University of Toronto, Scarborough. Theirs was not a study of inadvertent communication failures.
