5:35 PM | Expanding particles to engineer defects
Materials scientists have long known that introducing defects into three-dimensional materials can improve their mechanical and electronic properties. Now a new study finds how defects affect two-dimensional crystalline structures, and the results hold information for designing new materials.

After installing a Linux Mint operating system (OS) as a “dual boot” setup alongside Windows 8 (not as bad as I’d heard!), I was hoping I’d be able to use some of the software I have student licenses for without having to restart each time. The open source LibreOffice just isn’t as smooth as Office 2013 packages, Office365 was made for the lightest of users and more than anything I’m comfortable as I was in the Office setup, with university supported […]

2:00 PM | The story of the phospholipase A superfamily
  The phospholipase A2 superfamily is a group of enzymes that cleave fatty acid groups from glycerol, in particular acyl groups at the sn-2 position. They contribute to numerous metabolic processes and diseases, including Alzheimer, epilepsy and multiple sclerosis; making this group of proteins very attractive to study. This superfamily includes groups such as secreted, […]

1:03 PM | The System Actually Works
Once people start distrusting the government, it is difficult to get them to reconsider, but this might: PlasticsNews is reporting that the Environmental Portection Agency (EPA) has told a New Jersey company to stop selling food containers with nanoparticles of silver in it.The company had not registered the pesticide with the EPA as they were required to. "Part of the registration process is qualifying that a product does not put human health at risk when used as it is intended...".It's pretty […]

12:21 PM | Scientists disagree on responsible research
New research reveals that the scientists place great emphasis on behaving responsibly; they just disagree on what social responsibility in science entails. Responsibility is, in other words, a matter of perspective.

12:16 PM | Domain walls in nanowires cleverly set in motion
Researchers have achieved a major breakthrough in the development of methods of information processing in nanomagnets. Using a new trick, they have been able to induce synchronous motion of the domain walls in a ferromagnetic nanowire.

12:01 PM | Scalable CVD process for making 2-D molybdenum diselenide
Researchers have unveiled a potentially scalable method for making one-atom-thick layers of molybdenum diselenide - a highly sought semiconductor that is similar to graphene but has better properties for making certain electronic devices like switchable transistors and light-emitting diodes.

10:35 AM | The role of magnetic nanoparticles in breast cancer treatment
This evolving treatment approach involves the injection of nanoparticles into the tumor, which are then activated with magnetic energy. Once activated the nanoparticles produce heat inside the cancer cell. The heat kills the cancer cell with minimal damage to surrounding tissue.

10:31 AM | Graphene nanoribbons as electronic switches
A new theoretical study shows the conductivity conditions under which graphene nanoribbons can become switches in externally controlled electronic devices.

5:53 AM | Gold nanorods attach to, kill bladder cancer cells
Bladder cancer cells overexpress the protein EGFR; gold nanorods can be engineered to attach to EGFR proteins; and then the application of low-intensity laser to the tissue can preferentially heat these gold nanorods, killing the EGFR-rich cancer cells to which they are attached.

12:07 AM | Mr. Buffett's chemists (not really)
I'm not a member of The Cult Of Warren Buffet, but I enjoy reading Berkshire Hathaway's annual report. It's eminently readable as far as annual reports go -- you can imagine Warren Buffett sitting there, happily typing away on his computer. My favorite quote from Buffett was from the 2010 letter, where he publishes his advice to his managers on potentially questionable business moves (emphasis mine):If you see anything whose propriety or legality causes you to hesitate, be sure to give me a […]

9:30 PM | This week's C&EN
A variety of tidbits from this week's C&EN:I had no idea there were drugs to treat hearing loss, but Lisa Jarvis sets me straight. Interesting news from Ann Thayer that GSK is looking at building plants in Africa.Slightly more women faculty members are being hired. (by Sophie Rovner)Also, an interesting letter to the editor: It is upsetting that C&EN would feature an image of a burned animal being probed by a spectroscopist as some kind of evidence for progress in health […]

8:36 PM | 20-805 analyzer control calibrations
This post explains some tests and calibrations for the 20-805 analyzer control which is used on older Physical Electronics (PHI) ESCA, XPS and AES surface analysis systems. The 20-805 analyzer control is typically used to control the 15-255G and 25-260 … Continue reading → The post 20-805 analyzer control calibrations appeared first on RBD TechSpot.

4:17 PM | Why is a dog eating chemical-free deodorant?
During this past winter, Atoms and Numbers saw an incredible spike in traffic to my post on chemical-free chemistry sets. Most of the additional visitors came from Facebook, and due to their privacy setup, I could not locate the posts that generated the traffic, but I trust the readers enjoyed that post. I reread that post […]

4:06 PM | Trees go high-tech: process turns cellulose into energy storage devices
Chemists have found that cellulose - the most abundant organic polymer on Earth and a key component of trees - can be heated in a furnace in the presence of ammonia, and turned into the building blocks for supercapacitors.

2:36 PM | Even thinner solar cells through use of nanoparticles?
Researchers have measured how irregularly distributed silver particles influence the absorption of light. They demonstrated that nanoparticles interact with one another via their electromagnetic near-fields, so that local 'hot spots' arise where light is concentrated especially strongly.

2:13 PM | Coke Committed To PlantBottle Despite JBF Bio-based Ethylene Glycol Cancellation
Here’s something that wasn’t very well publicized: JBF Industries has cancelled its project to build a bio-based ethylene glycol plant in Brazil. The company, and Indian polyethylene terephthalate producer, disclosed that it was putting the project “on hold” as part of its earnings back in August. This is a far cry from the original announcement […]

1:24 PM | Stuck in a career rut
As a member you're entitled to free confidential careers advice but what does this mean for you? Over the next few weeks I shall give you some scenarios. Today we look at networking. With 30% of all jobs (regardless of sector, experience or qualifications) increasing to 80% of jobs in the graduate/professional sectors being filled through networking, it's clearly an option worth looking at. Ah, but what about the fact all jobs have to be advertised I hear you cry. Unfortunately it doesn't […]

12:57 PM | Organic solar cells more efficient with molecules face-to-face
New research reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.

12:08 PM | New synthesis method for graphene using agricultural waste
Researchers have proposed an alternative way of making graphene from rice husk. This research, using an ordinary synthetic apparatus and abundant agricultural waste, suggest that low cost graphene materials could now be easily and cheaply synthesized on an industrial scale. Due to its abundance, risk husk has already received much attention as a starting material in generating high-value-added materials such as silica and porous carbon.
