Nanotechnology news

	Semiliquid battery competitive with both Li-ion batteries and supercapacitors (Phys.org)—A new semiliquid battery developed by researchers at The University of Texas at Austin has exhibited encouraging early results, encompassing many of the features desired in a state-of-the-art energy-storage device. In particular, the new battery has a working voltage similar to that of a lithium-ion battery, a power density comparable to that of a supercapacitor, and it can maintain its good performance even when being charged and discharged at very high rates.
	Double Janus nanoparticles transformed into cup-shaped dynamic inclusion bodies for colloid design The transport of nanparticles to a new target environment is often needed in medical applications. Inclusion bodies or host–guest systems are of special interest, however, their design is especially challenging, and nanocolloids formed from inorganic components are rare, although they have the advantage of being functionalized relatively easily. In the journal Angewandte Chemie, scientists from Stuttgart, Germany, describe an intriguing new approach to fabricate a functionalizable host–guest system from pure inorganic components. The system involves nanocup-shaped inorganic colloids that harbor gold nanoparticles, which can be easily released by an external stimulus.
	Artificial muscles get graphene boost Researchers in South Korea have developed an electrode consisting of a single-atom-thick layer of carbon to help make more durable artificial muscles.
	Physicists develop efficient method of signal transmission from nanocomponents Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal Nature Communications together with their colleagues from ETH Zurich.

	Researchers develop method of fabricating perovskite solar cells that is more efficient, costs less (Phys.org)—A team of researchers working at the Korea Research Institute of Chemical Technology in South Korea, has found a way to make fabricating perovskite based solar cells that is both more efficient and costs less than other current methods. In their paper published in the journal Science, the team describes their process and the efficiencies they were able to achieve.
	Visualizing how radiation bombardment boosts superconductivity Sometimes a little damage can do a lot of good—at least in the case of iron-based high-temperature superconductors. Bombarding these materials with high-energy heavy ions introduces nanometer-scale damage tracks that can enhance the materials' ability to carry high current with no energy loss—and without lowering the critical operating temperature. Such high-current, high-temperature superconductors could one day find application in zero-energy-loss power transmission lines or energy-generating turbines. But before that can happen, scientists would like to understand quantitatively and in detail how the damage helps—and use that knowledge to strategically engineer superconductors with the best characteristics for a given application.
	Star power: Troubled ITER nuclear fusion project seeks new path In 1985, then Soviet leader Mikhail Gorbachev and US president Ronald Reagan launched one of the unlikeliest ideas of the Cold War.
	From reverberating chaos to concert halls, good acoustics is culturally subjective Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play that same flute in the Grand Canyon, and the sound waves will crash against the rock walls, folding back in on each other in sonic chaos. The disparity in acoustics is clear - to the modern listener, the instrument belongs in an auditorium.
	Used MRI magnets get a second chance at life in high-energy physics experiments When it comes to magnets, a doctor's trash is a physicist's treasure.
	Sweeper demonstrates wide-angle optical phased array technology Many essential military capabilities—including autonomous navigation, chemical-biological sensing, precision targeting and communications—increasingly rely upon laser-scanning technologies such as LIDAR (think radar that uses light instead of radio waves). These technologies provide amazing high-resolution information at long ranges but have a common Achilles heel: They require mechanical assemblies to sweep the laser back and forth. These large, slow opto-mechanical systems are both temperature- and impact-sensitive and often cost tens of thousands of dollars each—all factors that limit widespread adoption of current technologies for military and commercial use.

New computational technique advances color 3-D printing process

Working with researchers at Zhejiang University in China, Changxi Zheng, assistant professor of computer science at Columbia Engineering, has developed a technique that enables hydrographic printing, a widely used industrial method for transferring color inks on a thin film to the surface of manufactured 3D objects, to color these surfaces with the most precise alignment ever attained. Using a new computational method they developed to simulate the printing process, Zheng and his team have designed a model that predicts color film distortion during hydrographic immersion, and uses it to generate a colored film that guarantees exact alignment of the surface textures to the object. The research will be presented at SIGGRAPH 2015, August 9 to 13, in Los Angeles.

Study finds cells that become sperm or eggs in humans are vulnerable during pregnancy

A new study, published online today by Amander Clark, Ph.D., at the UCLA Eli & Edythe Broad Center of Regenerative Medicine and Stem Cell Research, significantly furthers the understanding of the human germline – the cells that create eggs or sperm in humans during prenatal development in the womb. The highly specialized cells of the germline, called germ cells, are the only cell type in the body capable of passing parents' genes on to their biological children. Abnormalities in the germ cells can cause infertility as well as diseases such as germ cell tumors in young boys and primary ovarian insufficiency in young girls. Published by the journal Cell, the study looks closely at how the genetic information of prenatal germ cells is shielded from harm during prenatal life, showing that these important cells lack protection during a phase of development, leaving them vulnerable to damage.

An evolutionary heads-up—the brain size advantage

A larger brain brings better cognitive performance. And so it seems only logical that a larger brain would offer a higher survival potential. In the course of evolution, large brains should therefore win out over smaller ones. Previous tests of this hypothesis had relied on comparison studies looking at the intelligence and survival potential of species with large brains versus species with smaller brains. And species with larger brains do appear to have an advantage. But such studies are unable to show a causal relationship.

Human stem cell model reveals molecular cues critical to neurovascular unit formation

Crucial bodily functions we depend on but don't consciously think about—things like heart rate, blood flow, breathing and digestion—are regulated by the neurovascular unit. The neurovascular unit is made up of blood vessels and smooth muscles under the control of autonomic neurons. Yet how the nervous and vascular systems come together during development to coordinate these functions is not well understood. Using human embryonic stem cells, researchers at University of California, San Diego School of Medicine and Moores Cancer Center and Sanford-Burnham Medical Research Institute created a model that allows them to track cellular behavior during the earliest stages of human development in real-time. The model reveals, for the first time, how autonomic neurons and blood vessels come together to form the neurovascular unit.
