Research accelerates quest for quicker, longer-lasting electronics
In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalizing potential. In a paper published today in 'Science Advances,' Jing Shi, a professor of physics and astronomy at UC Riverside and colleagues MIT and Arizona State University report they have created a TI film just 25 atoms thick that adheres to an insulating magnetic film, creating a 'heterostructure.'

Holey pattern boosts coherence of nanomechanical membrane vibrations
Researchers at the Niels Bohr Institute have introduced a new type of nanomechanical resonator, in which a pattern of holes localizes vibrations to a small region in a 30 nm thick membrane. The pattern dramatically suppresses coupling to random fluctuations in the environment, boosting the vibrations' coherence. The researchers' quantitative understanding and numerical models provide a versatile blueprint for ultracoherent nanomechanical devices. Among others, this enables a new generation of nanomechanical sensors to probe quantum limits of mechanical measurements, and more sensitive force microscopy.

Smooth propagation of spin waves using gold
Assistant Professor Taichi Goto at Toyohashi University of Technology elucidated the noise generation mechanism of the spin wave (SW), the wave of a magnetic moment transmitted through magnetic oxide, and established a way to suppress it. The large noise generated by SWs traveling through magnetic oxides has presented a significant obstacle to its applications. However, it became clear that noise can be suppressed by installing a thin gold film in the appropriate places.

Switchable DNA mini-machines store information
Biomedical engineers have built simple machines out of DNA, consisting of arrays whose units switch reversibly between two different shapes. The arrays' inventors say they could be harnessed to make nanotech sensors or amplifiers. Potentially, they could be combined to form logic gates, the parts of a molecular computer.

Drip by drip
How do crystals grow? The answer given in current textbooks is: Layer by layer atoms or molecules settle on an existing crystal surface. The research team Physical Chemistry at the University of Konstanz has now observed a preliminary stage of this crystal growth in glutamic acid that contradicts this classical principal of growth. Not individual atoms settle on an existing crystal surface, but nano-drips that already contain building blocks for growth.

Extremely colorful, incredibly bright and highly multiplexed
A team from Harvard's Wyss Institute for Biologically Inspired Engineering, the LMU Munich, and the Max Planck Institute of Biochemistry in Germany, has engineered highly versatile metafluorophores by integrating commonly used small fluorescent probes into self-folding DNA structures where their colors and brightness can be digitally programmed. This nanotechnological approach offers a palette of 124 virtual colors for microscopic imaging.

Researchers developed nanoparticle based contrast agent for dual modal imaging of cancer
Dual modal imaging which shares the advantages of two imaging modalities such as magnetic resonance imaging and optical imaging, has the ability to produce images with higher spatial resolution and higher sensitivity. Contrast agents having both magnetic and optical properties identifies the cancer cells efficiently. Europium doped gadolinium oxide nanorods were synthesized and subsequently coated with silica to improve the biocompatibility.

Tiny bubbles provide tremendous propulsion in new microparticles research-Ben-Gurion U.
The new technique could have significant implications in the development of micromotors and optical devices for use in solar cell optics. 'What we ultimately hope to achieve is a highly accurate, passive technology for use in a concentrated solar device that would follow the sun without the need for a mechanical tracking mechanism,' says Dr. Avi Niv, study co-author.

Possible enhanced pesticide absorption from fresh food via nanoemulsions
University of Massachusetts Amherst food scientist David Julian McClements will lead a team that has received a three-year, $444,550 grant from the US Department of Agriculture's National Institute of Food and Agriculture to study the possibility that eating food nanoemulsions found in dressings, dips or sauces might increase the amount of pesticides absorbed from co-ingested fruits and vegetables, thus increasing risk of adverse health effects.

Sugar-coated nanomaterial excels at promoting bone growth
There hasn't been a gold standard for how orthopaedic spine surgeons promote new bone growth in patients, but now Northwestern University scientists have designed a bioactive nanomaterial that is so good at stimulating bone regeneration it could become the method surgeons prefer. The researchers studied in vivo the effect of the nanomaterial on the activity of the growth factor BMP-2. They found that 100 times less of the protein was needed for a successful spinal fusion in an animal model.

To connect biology with electronics, be rigid, yet flexible
Scientists have measured a thin film made of a polymer as it interacted with ions and electrons. They show how there are rigid and non-rigid regions of the film, and that these regions could accommodate electrons or ions -- but not both equally.

New prospects for universal memory -- high speed of RAM and the capacity of flash
One of many research teams and companies' major goals is to develop universal memory -- a storage medium that would combine the high speed of RAM with nonvolatility of a flash drive. MIPT's researches turned to atomic layer deposition which enables unprecedented control over film thickness and coating of 3-D structures, which is problematic for most of the currently used nanofilm deposition techniques. To do this, the team worked with a unique experimental cluster form MIPT's Center of Shared Research Fcailities.

Electrolytes made from liquefied gas enable batteries to run at ultra-low temperatures
Engineers at the University of California San Diego have developed new electrolytes that enable lithium batteries to run at temperatures as low as -60 degrees Celsius with excellent performance -- in comparison, today's lithium-ion batteries stop working at -20 degrees Celsius. The new electrolytes also enable electrochemical capacitors to run as cold as -80 degrees Celsius -- their current limit is -40 degrees Celsius.
