4:19 PM | An optomechanical crystal to study interactions among colocalized photons and phonons
Electromagnetic radiation and mechanical vibrations of matter interact and exchange energy at the nanoscale. The experimental basis to study such interactions with precision is still being established. Researchers have now designed a silicon 1D Optomechanical crystal built up so that it allows to localize in a stable way both phonons and photons.

3:27 PM | What is a project house?
In an article by Alex Scott about Clariant and its R&D structure, an interesting paragraph (emphasis mine):The company now has eight R&D centers and 50 technical application labs worldwide. “We now have a very good infrastructure for trying to develop innovations,” Kottmann said. Clariant is also testing models for accelerating innovation. One such model, in trials for the past couple of years, is the so-called project house, which draws together chemists and commercial […]

3:22 PM | C&EN tackles chronic traumatic encephalopathy
Lauren Wolf looks at scientists trying to track the accumulation of tau (and other signs of CTE) in vivo: ...One question they’d like to answer is how much brain injury a person can handle before CTE sets in. With support from the Nevada Athletic Commission and local fight promoters, the group is gathering data by periodically testing its fighters and comparing them with a control group of age- and education-matched people who have never had head trauma. When the test subjects visit […]

3:06 PM | This week's C&EN
From this week's issue: Wonderful quotes on committees: This letter on open workspaces takes a funny turn towards the end:...Teamwork and collaboration are important, but so is individual thought. The late science-fiction writer Robert Heinlein defined a committee as “a creature with three or more legs and no brain.” The National Aeronautics & Space Administration put it similarly: “None of us is as dumb as all of us.” James M. CastroHelena, Mont.Um, what's […]

2:44 PM | Carbyne morphs from metal to semiconductor when stretched
Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator, according to Rice University scientists.

12:16 PM | XPS and AES peak linearity adjustments
This post is a compilation of some calibration tech tips that I have written over the years. The procedures listed below explain how to calibrate the following systems and units: 5600 and 5400 XPS systems, Double pass CMA XPS analyzers … Continue reading → The post XPS and AES peak linearity adjustments appeared first on RBD TechSpot.

11:40 AM | DNA used as a nano-gold lightswitch
A nanostructure made from two tiny gold rods reversibly changes its optical properties when specific DNA molecules are added.

11:02 AM | New annotated journal articles
Research has shown that students can find it difficult to interpret and understand the information in journal articles, which can cause problems when they arrive at university and need to start using journals independently. As an organisation with a market leading journal portfolio and ambitions to encourage the growth of the chemical sciences by the dissemination of chemical knowledge, we decided to tackle this problem by creating an annotated journal article series. The series is […]

10:20 AM | New spongelike structure converts solar energy into steam
The structure - a layer of graphite flakes and an underlying carbon foam - is a porous, insulating material structure that floats on water. When sunlight hits the structure's surface, it creates a hotspot in the graphite, drawing water up through the material's pores, where it evaporates as steam.

10:11 AM | Scientists explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs (w/video)
A new study from MIT materials scientists reveals that gold nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons. They describe in detail the mechanism by which these nanoparticles are able to fuse with a membrane.

10:02 AM | Haydale and Goodfellow Announce Major Distribution Agreement for Functionalised Graphene Materials
Haydale, a company focused on enabling technology for the commercialisation of graphene, has announced a non-exclusive agreement with Goodfellow, a leading supplier and marketer of metals and materials for industry and research.

6:58 AM | Foursquare closes another door
With the latest update to its Android app, Foursquare now forces check ins to be done via Swarm (my workround involving uninstalling Swarm no longer works). This means that points are harder to get for frequently checked in locations. It’s still possible to get them if Foursquare itself recognises the location you’re at and invites […]

3:19 AM | Review: ChemBioDraw 14.0
Dear ChemBioDraw* Ultra 13.0,Listen, we had a good run together. But I've fallen for another: ChemBioDraw Ultra 14.My good friends at PerkinElmer (PKI) were kind enough to grant me trial access to their spiffy new chemistry drawing software. As an avid user since, oh, say, ChemDraw Pro 4.5, I feel confident in stating that this version wins all around for smoother operation, better templates, easier file export, and better shortcut keys.So, I figured what PKI really wanted me to do most […]

11:01 PM | The problem with Food Babe
The Charlotte Observer has a good article on Food Babe, a health and nutrition activist who has been responsible for many a scientist and science writer's heartburn over the last few years, and not for good reasons.The article places Food Babe's current activism against processed food and many food ingredients in a personal context; as is often the case, her conversion was triggered by many things, but most precipitously by an epiphany:"Sometimes when she tells her story, she says she suffered […]

11:18 AM | Tablet shortcomings, or should I keep taking the tablet?
About a year ago I posted about taking a tablet on a research trip to Vienna in place of a laptop. I was pretty positive about the overall experience. At the time I was using a budget Coby Kyros tablet, but it managed to do almost everything I needed it to do. Since then I […]

5:18 PM | Martini Tech Inc. Becomes Exclusive Distributor for Yoshioka Seiko Co. Porous Chucks for Europe and North America
Differently from other mechanical chucks, porous chucks use a pressure differential between the front and back side of the surface in order to hold the substrate: using this technique it is possible to work on extremely thin substrates without any risk of breakage.

3:34 PM | CEO apparently cannot afford to train his workers
Via my new weekly dose of pain (a Google news alert for the term "skills gap"), a CEO has a good one (emphasis mine): ...Yet in manufacturing alone, a half-million jobs are going unfilled because firms have been unable to find qualified workers. The feds can't address our nation's shortage of skilled labor on their own. Private firms — especially those in manufacturing — must also invest in training. Indeed, without workers fluent in the high technology that runs today's […]

2:36 PM | The Real David Bradley
I feel awfully guilty calling myself “the real David Bradley” now that I’ve met the actor who played Argus Filch in the Harry Potter films and William Hartnell alongside actor Brian Cox in the BBC Dr Who period drama “An Adventure in Space and Time”. I just happened to bump into him in a pub […]The Real David Bradley is a post from the science blog of David Bradley, author of Deceived Wisdom Subscribe to our Email Newsletter

12:56 PM | Publication of the week, number 34, 18th July 2014: Addendum
Firstly, thanks to the authors for providing me with a full copy of their supplementary information. No doubt Angewandte will get round to posting it soon. I must congratulate them on an extremely comprehensive SI. Full experimentals, of course, with HPLC data for the %ee and all the relevant NMR’s. And  conversion of new compounds […]

12:22 PM | How biased are you, when you check the literature?
As scientists, we tend to think of ourselves as (at least) a little less biased than the average person. However, we still have to rely on mental shortcuts to classify information regarding its importance, relevance and trustworthiness. These shortcuts allow us to survive among the wealth of information we take from our environment, but are also prone to over-simplification and inevitably lead to bias. When I browse my RSS feeds, or the lists of hits in a PubMed or Web of Science query, I have […]
