    What if your cell phone didn't come with a battery? Imagine, instead, if the material from which your phone was built was a battery. The promise of strong load-bearing materials that can also work as batteries represents something of a holy grail for engineers. And in a letter published online in Nano Letters last week, a team of researchers from Vanderbilt University describes what it says is a breakthrough in turning that dream into an electrocharged reality. The researchers etched nanopores into silicon layers, which were infused with a polyethylene oxide-ionic liquid composite and coated with an atomically thin layer of carbon. In doing so, they created small but strong supercapacitor battery systems, which stored electricity in a solid electrolyte, instead of using corrosive chemical liquids found in traditional batteries.

    Researcher studies crystal growth that may lead to biomaterials for both and tooth repair In nature, some organisms create their own mineralized body parts--such as bone, teeth and shells--from sources they find readily available in their environment. Certain sea creatures, for example, construct their shells from calcium carbonate crystals they build from ions found in the ocean. "The organism takes brittle carbonate and turns it into a structural shape that protects it from predators, and from being bashed against the rocks," says Lara Estroff, an associate professor of materials science and engineering at Cornell University. "There is much scientific interest in how the organism controls the crystal growth, and what mechanisms are involved in strengthening and toughening the shells, especially in comparison to their components, which are brittle."

Koyal Info Group Mag Discovery of Oxygen in Soils - 1 views

    Koyal Info Group Mag Discovery of Oxygen in Soils New discoveries show biological formation of oxygen in soils In the 1930s, the ability of green plants to form oxygen through oxidation of water -- photosynthesis -- was discovered. Since then, no other large-scale biological formation of oxygen has been found, until now. New research results show that down in the dark depths of the soil, a previously unknown biochemical process is under way, in which oxygen is formed and carbon dioxide is reduced to organic material. He made the assumption that the bewildering result could be explained if water, which is present everywhere, contributes to reducing carbon dioxide to organic material down in the dark depths of the soil. The fact that this process takes place without sunlight, as is the case with plants, was however something completely outside current knowledge and accepted views. Professor Fleischer, however, went further, with this as his working hypothesis. An international assessment of the scientific research, carried out at Halmstad University in 2013, called the results "potentially ground-breaking." Professor Fleischer conducted the five-year project in collaboration with Lovisa Bauhn and Arvid Ödegaard-Jensen of the Division of Nuclear Chemistry at Chalmers University, and Patrik Fors at Vattenfall.

    The Koyal Group Info Mag on Unusual square ice discovered The surprising discovery of "square ice" which forms at room temperature was made by an international team of researchers last week. The study was published in Nature by a team of scientists from UK and Germany led by Andre Geim of University of Manchester and G. Algara-Siller of University of Ulm. The accompanying review article was done by Alan Soper of Rutherford Appleton Laboratory in UK. "We didn't expect to find square ice ... We found there is something strange in terms of water going through [nanochannels]. It's going too fast. And you can't explain that by just imagining a very thin layer of liquid. Liquids do not behave in that way. The important thing to realize is that it is ice in the sense of a crystallized structure, it's not ice in the familiar sense in that it's something cold and from which you have to protect yourself," said Professor Irina Grigorieva, one of the researchers. To study the molecular structure of water inside a transparent nanoscale capillary, the team used electron microscopy. This enabled them to view individual water molecules, especially because the nano-capillary was created from graphene which was one atom thick and would not impair the electron imaging. Graphene was also chosen because it has unusual properties like conducting electricity and extreme strength. It's a 2D form of carbon that once rolled up in cylinders will form a carbon nanotube, a material, which according to The Koyal Group Info Mag, is a subject of further study because of its unusual strength. The scientists themselves were admittedly surprised at finding out that small square-shaped ice crystals formed at room temperature where the graphene capillaries are narrow (3 atomic layers of water at most). The water molecules formed into square lattices arranged in neat rows -- an arrangement that is uncharacteristic for the element that is known for forming consistent triangular structures

The Koyal Group Journals, Milk fraud: Proteins uncover adulteration with cheaper milk - 1 views

  •  
    Mixing milk Food adulteration is an unsavoury fact of modern life. Many foodstuffs are targeted by criminal gangs because of their high value, so mixing them with cheaper alternatives while selling at the price of the pure material leads to higher profits. Pursue this tactic at the national or international scale and there is good money to be made. One of the more surprising foods that have been targeted is milk. Not the common cows' milk that we drink in the Western world, but milk from more exotic species likes the yak, buffalo or camel. These types have been mixed with milk from the cow or goat, and goat milk itself has been adulterated with cheaper cow milk. It is difficult to see or taste the difference when milk has been adulterated but scientific methods are available.
