The trend toward energy self-sufficient probes and ever smaller mobile electronics systems continues unabated. They are used, for example, to monitor the status of the engines on airplanes, or for medical implants. They gather the energy they need for this from their immediate environment - from vibrations, for instance. Researchers have developed a process for the economical production of piezoelectric materials.

9:00 PM | The Moon Re-examined.
Recently, there have been two themes regarding the Moon's origin. Some unexpected but now well-known results from the samples returned by Apollo included: 1. the rocks were remarkably dry, 2. the isotopes of oxygen and some other elements were essentially the same as those of Earth whereas these isotope ratios differ from other samples, such as chondrites, and from Mars, 3. there was considerable anorthosite, which is a feldspathic mineral, present. Earth is the only planet that we know of that […]

10:05 AM | Strained Acetylenes
Spotted fleetingly last week was a publication by Danheiser in JACS detailing the preparation  and reactions of the strained cyclic ynamide: Now this is an unusual compound, just think what you can do with the chemistry of arynes. Of course it is not as stable as the aromatic variant which makes its synthesis and chemistry all the […]

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 […]

6:47 AM | Ambition [Vídeo]
Quedan pocos días para que la sonda Rosetta se pose sobre el cometa 67P/Churiumov-Guerasimenko. Un acontecimiento histórico que nos tiene en vilo a todos los aficionados a la exploración espacial. Sí, ya sé que se ha dicho casi todo sobre Rosetta y Philae, hay cientos de fotos y post por ahí, y tal y cual... Vale, pero tenéis que ver este vídeo. Los fanboys de Juego de tronos o de The wire (mi caso) reconocerán a uno de […]

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 […]

3:27 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!

2:31 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 […]

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 […]
