Physical Review X
Manipulating electron spins without loss of information
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel's Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

'Nano-in-micro' stem cell delivery could rescue blood flow after injury
When blood flow is reduced or cut to tissues, cells are deprived of oxygen and nutrients, which can lead to cell death if blood flow isn't efficiently restored. Stem cells are promising treatments, but they do not tend to stay at the site or survive long enough to heal the damage. Today in ACS Central Science, researchers combine micro and nano approaches to improve stem cell therapies and outcomes after ischemia, or inadequate blood supply.

SLAS Discovery
Control of the unfolded protein response in health and disease
Information generated by screening tools, readily available therapies and potential pathways to drug development are the cornerstone of informed clinical research and clinical trial design. In a new review in the August 2017 issue of SLAS Discovery (formerly the Journal of Biomolecular Screening), authors Eric Chevet, Ph.D., of Inserm U1242 (Rennes, France) et al. analyze the recent literature and review the impact of unfolded protein response (UPR) in health and disease.

The new technology for porous material production
The new technology of producing unsinkable material from the aluminum alloy was patented at Peter the Great St. Petersburg Polytechnic University. The effect of porosity is produced by addition of foaming gas into liquid metal during re-melting of the aluminum material. The porous materials can be used for increase of structures stiffness and sound and heat insulating proprieties.

Tiny particles increase in air with ethanol-to-gasoline switch
The concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of São Paulo, Brazil, when higher ethanol prices induced drivers to switch from ethanol to gasoline, according to a new study by a Northwestern University chemist, a National University of Singapore economist and two University of São Paulo physicists. The research team also found when drivers switched back to ethanol because prices had gone down, the concentration of ultrafine particles also went down.

Breathable, wearable electronics on skin for long-term health monitoring
A hypoallergenic electronic sensor can be worn on the skin continuously for a week without discomfort, and is so light and thin that users forget they even have it on, says a Japanese group of scientists. The elastic electrode constructed of breathable nanoscale meshes holds promise for the development of noninvasive e-skin devices that can monitor a person's health continuously over a long period.

Coupling a nano-trumpet with a quantum dot enables precise position determination
Scientists from the Swiss Nanoscience Institute and the University of Basel have succeeded in coupling an extremely small quantum dot with 1,000 times larger trumpet-shaped nanowire. The movement of the nanowire can be detected with a sensitivity of 100 femtometers via the wavelength of the light emitted by the quantum dot. Conversely, the oscillation of the nanowire can be influenced by excitation of the quantum dot with a laser. Nature Communications published the results.

Hamburg researchers develop new transistor concept
Transistors, as used in billions on every computer chip, are nowadays based on semiconductor-type materials, usually silicon. As the demands for computer chips in laptops, tablets and smartphones continue to rise, new possibilities are being sought out to fabricate them inexpensively, energy-saving and flexibly. The group led by Dr. Christian Klinke has now succeeded in producing transistors based on a completely different principle.

Laser-cooled ions contribute to better understanding of friction
Scientists from the QUEST Institute at the Physikalisch-Technische Bundesanstalt (PTB) have presented a model system which allows the investigation of atomic-scale friction effects and friction dynamics that are similar to those taking place, e.g., in proteins, DNA strands and other deformable nanocontacts. This model system consists of laser-cooled ions, which arrange themselves in so-called Coulomb crystals.

New material resembling a metal nanosponge could reduce computer energy consumption
Researchers from the UAB, in collaboration with the ICN2, have developed a nanoporous material based on a copper and nickel alloy, with a structure similar to that of a sponge with pores measuring the size of a millionth of a millimeter, which allows handling and storing information using very little energy. These nanosponges could be the base of new magnetic memories for computers and mobile phones with greater energy efficiency than those currently existing.

Researchers develop technique to control and measure electron spin voltage
Information technologies of the future will likely use electron spin -- rather than electron charge -- to carry information. But first, scientists need to better understand how to control spin and learn to build the spin equivalent of electronic components and tools. Now, Harvard researchers have developed a technique to control and measure spin voltage, known as spin chemical potential. The technique, which uses atomic-sized defects in diamonds is essentially a nanoscale spin multimeter that allows measurements in chip-scale devices.

Feedback from thousands of designs could transform protein engineering
A large-scale study to test the actual stability of computationally designed proteins shows a way to take some of the guesswork out of protein engineering. Previously, scientists tested only a few tens of proteins, due to prohibitive costs of DNA. This new approach, which incorporates advances in DNA synthesis technology, efficiently checks thousands of mini-protein designs. The hope is that in the future a similar approach could test bigger, more complex, designed proteins.
