Chemists create modular system for placing proteins on membranes

April 21, 2015 8:12 am | by Susan Brown, Univ. of California, San Diego | News | Comments

With a tag, an anchor and a cage that can be unlocked with light, chemists have devised a simple, modular system that can locate proteins at the membrane of a cell. The chemists fused proteins to molecules called SNAP-tags, modified enzymes that recognize a particular chemical group called a benzylguanine.

Better battery imaging paves way for renewable energy future

April 21, 2015 8:04 am | by Univ. of Wisconsin-Madison | News | Comments

In a move that could improve the energy storage of everything from portable electronics to electric microgrids, Univ. of Wisconsin-Madison and Brookhaven National Laboratory researchers have developed a novel x-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.

Electronic device performance enhanced with new transistor encasing method

April 21, 2015 7:50 am | by Austin Keating, News Bureau Intern, Univ. of Illinois, Urbana-Champaign | News | Comments

A more effective method for closing gaps in atomically small wires has been developed by Univ. of Illinois researchers, further opening the doors to a new transistor technology. Silicon-based transistors have been the foundation of modern electronics for more than half a century. A new transistor technology, carbon nanotube wires, shows promise in replacing silicon because it can operate ten times as fast and is more flexible.

No. 1023 is a 550 F, electrically heated, Class 100 cleanroom cabinet oven from Grieve Corp., currently used for curing small rubber pieces in rotating drums at the customer’s facility. Workspace dimensions of this oven measure 26 in W x 26 in D x 60 in H.

New tabletop detector “sees” single electrons

April 21, 2015 7:37 am | by Jennifer Chu, MIT News Office | News | Comments

Massachusetts Institute of Technology physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas. As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the electrons, which can be used to map the electrons’ precise activity over several milliseconds.

The magnetic coercivity, the resistance to change in the orientation of the magnetic domain structure, for nickel (Ni) was shown to strongly depend on the crystal structure of the underlying oxide (vanadium oxide). The maximum Ni coercivity occurs at the

Giant magnetic effects induced in hybrid materials

April 20, 2015 2:22 pm | by Department of Energy, Office of Science | News | Comments

Proximity effects in hybrid heterostructures, which contain distinct layers of different materials, allow one material species to reveal and/or control properties of a dissimilar species. Specifically, for a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition.

Applied physics helps decipher the causes of sudden death

April 20, 2015 2:10 pm | by Universitat Politècnica de Catalunya (UPC) | News | Comments

Sudden cardiac death accounts for approximately 10 percent of natural deaths, most of which are due to ventricular fibrillation. Each year it causes 300,000 deaths in the United States and 20,000 in Spain. Researchers have demonstrated for the first time that the transition to calcium alternans, an arrhythmia associated with increased risk of sudden death, has common features with the magnetic ordering of metals.

For the first time, researchers predicted the properties of granular Platonic solids (crystalline) packs and discovered a significant shape effect in their overall thermo-mechanical behavior.

New paper opens the door to the study of a new class of materials

April 20, 2015 12:51 pm | by William G. Gilroy, University of Notre Dame | News | Comments

A new paper describes how an accurate statistical description of heterogeneous particulate materials, which is used within statistical micromechanics theories, governs the overall thermo-mechanical properties. This detailed statistical description was computed using a novel adaptive interpolation/integration scheme on the nation’s largest parallel supercomputers.

How to maximize the superconducting critical temperature in a molecular superconductor

April 20, 2015 12:38 pm | by Tohoku Univ. | News | Comments

A research team has investigated the electronic properties of the family of unconventional superconductors based on fullerenes, which have the highest known superconducting critical temperature among molecular superconductors, and was able to demonstrate the guiding influence of the molecular electronic structure in controlling superconductivity and achieving maximum Tc.

Tim Studt here again, and mostly recovered from my day-long travel on Friday. Hot and humid here in Taipei, about 25 F warmer than in Chicago. Today's judging at the Taiwan Excellence Awards covered healthcare-based tablet computers, electronic memory modules, top-end gaming computers, electric scooters, racing bicycles and even off-road mountain racing bike tires.

New tactic targets brain tumors

April 20, 2015 11:41 am | by Mike Williams, Rice Univ. | Videos | Comments

Drugs that target insulin pathways to slow or stop the growth of brain tumors are going in the right direction, but appear to be on the wrong track, according to new research. Through detailed computer models and experiments on two distinct glioblastoma cell types, the researchers have found reason to believe therapies that attack the insulin signaling pathway thought to influence tumor development have had mixed results in trials.

Advances in molecular electronics

April 20, 2015 10:27 am | by Helmholtz-Zentrum Dresden-Rossendorf | News | Comments

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf and the Univ. of Konstanz are working on storing and processing information on the level of single molecules to create the smallest possible components that will combine autonomously to form a circuit. As recently reported in Advanced Science, the researchers can switch on the current flow through a single molecule for the first time with the help of light.

Quantum model helps solve mysteries of water

April 20, 2015 10:19 am | by National Physical Laboratory | News | Comments

Water is one of the most common and extensively studied substances on earth. It’s vital for all known forms of life but its unique behavior has yet to be explained in terms of the properties of individual molecules. Water derives many of its signature features from a combination of properties at the molecular level such as high polarizability, directional hydrogen bonding sites and van der Waals forces.

Pulsing light may indicate supermassive black hole merger

April 20, 2015 10:11 am | by Abby Robinson, Univ. of Maryland | News | Comments

As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a "binary," or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers at the Univ. of Maryland present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.
