New inexpensive device splits water into hydrogen, oxygen
This image shows two electrodes connected via an external voltage source splitting water into oxygen (O2) and hydrogen (H2).
Researchers at Stanford University have developed an inexpensive device that uses light to split water into oxygen and clean-burning hydrogen. The goal is to supplement solar cells with hydrogen-powered fuel cells that can generate electricity when the sun isn’t shining or demand is high. Scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device – a silicon semiconductor coated in an ultrathin layer of nickel – could help pave the way for large-scale production of clean hydrogen fuel from sunlight, according to the scientists.

Scientists create large graphene with exceptional electrical properties
Rodney S Ruoff, Professor, Cockrell School of Engineering.
When it comes to the growth of graphene – an ultrathin, ultrastrong, all-carbon material – it is survival of the fittest, according to researchers at The University of Texas at Austin.The team used surface oxygen to grow centimetre-size single graphene crystals on copper. The crystals were about 10,000 times as large as the largest crystals from only four years ago. Very large single crystals have exceptional electrical properties.Read More
Gut bacteria increases immunity
In a mouse model for experimental colitis, a diet supplemented with butyric acid leads to decreased infiltration of inflammatory cells
New research from the RIKEN Centre for Integrative Medical Sciences in Japan sheds light on the role of gut bacteria on the maturation of the immune system and provides evidence supporting the use of butyrate as therapy for inflammatory bowel diseases like Crohn’s disease.The study shows that butyrate, a by-product of the digestion of dietary fibre by gut microbes, acts as an epigenetic switch that boosts the immune system by inducing the production of regulatory T cells in the gut.Read More
New promising method to detect cocaine in biofluids
Cocaine may permanently damage proteins in the body.
A new study on cocaine, details how it may permanently damage proteins in the body. According to scientists, the information, gleaned from laboratory tests, could be used to potentially detect the drug in biofluids for weeks or months – instead of days – after use. The findings, which appear in the ACS journal Chemical Research in Toxicology, could also help explain cocaine’s long-term health effects.Read More
Good cholesterol to treat heart diseases
Good cholesterol to treat diseases.
A new type of “good cholesterol,” made in the lab, could one day deliver drugs to where they are needed in the body to treat disease or be used in medical imaging, according to scientists. The high-density lipoprotein (HDL) mimic is easy to make in large amounts. Researchers Zahi A Fayad, Robert Langer, YongTae (Tony) Kim, Francois Fay, Willem Mulder and colleagues explained that HDL is a natural nanoparticle that carries cholesterol throughout the body.

Scientists discover metallic carbon
3D Metallic carbon with interlocking hexagons.
A theoretical, three-dimensional (3D) form of carbon that is metallic under ambient temperature and pressure has been discovered by an international research team.Carbon science is a field of intense research. Not only does carbon form the chemical basis of life, but it has rich chemistry and physics, making it a target of interest to material scientists. From graphite to diamond to Buckminster fullerenes, nanotubes and graphene, carbon can display in a range of structures. But the search for a stable three-dimensional form of carbon that is metallic under ambient conditions, including temperature and pressure, has remained an ongoing challenge for scientists in the field.

Engineered bacteria to synthesize drugs, biofuels
Kristala Jones Prather, Associate Professor, MIT.
Kristala Jones Prather, Associate Professor, MIT designed new ways to engineer bacteria to synthesize useful chemical compounds such as drugs and biofuels. Have been worked at Merck, Prather worked in many different areas, including biocatalysis — the use of bacterial enzymes to perform a reaction step that cannot be done cost-effectively using traditional chemical processes. Prather would develop an enzyme-driven reaction that could take place inside a cell, then send the resulting compound back into the chemical manufacturing process.Read More
The Ford Fusion Energi’s interior is lined with Coca-Cola plastic bottles materials.
Ford and Coca-Cola have entered into a partnership for car’s interior. The Ford Fusion Energi, a hybrid vehicle currently in development by the car company, uses the same material to line the car’s insides as Coke uses to make its plastic bottles. Read More
