Bonding chips using inkjet printers
A team of researchers at the University of Barcelona have demonstrated a new bonding technique for surface mounted devices that uses an inkjet printer with ink that incorporates silver nanoparticles. The technique, described this week in the Journal of Applied Physics, was developed in response to the industrial necessity for a fast, reliable and simple manufacturing process, and with an eye to reducing the environmental impact of the standard fabrication processes.

Simultaneous detection of multiple spin states in a single quantum dot
Osaka University-led researchers achieved single-shot readout of three two-electron spin states of a single quantum dot. This is the first example of simultaneous detection of multiple spin states in a single quantum dot. The team measured the change in current of a quantum point contact charge sensor near a quantum dot, which depended on both spin state and spin-orbital interactions. Their findings represent a step forward on the path to realizing quantum computing.

Technology Transfer and Entrepreneurship
Hold-up in ventures for technology transfer
The transfer of technology brings ideas closer to commercialization. The transformation happens in several steps, such as invention, innovation, building prototypes, production, market introduction, market expansion, after sales services. In each step, the owners with the technical know-how (the entrepreneur) and the owner of resources such as capital and command over networks (the investor) cooperate.

New application of the selective laser melting method
Scientists of Peter the Great St. Petersburg Polytechnic University (SPbPU) and Delft University of Technology developed a technology for obtaining new metal structures by selective laser melting method (additive technology of manufacturing three-dimensional objects from metal powders). New technology makes it possible to obtain a gradient microstructure of the material and create a product, combining properties of two metals. This material is characterized by high performance characteristics, such as temperature and pressure effects, strength, durability.

Single molecule switch
The progressing miniaturization of electronic components will reach a fundamental barrier at the dimension of single atoms. For this reason researchers in the field of molecular electronics aim at realizing functional electric circuits built from single atoms or molecules to explore the ultimate limit.

Guiding light: Sandia creates 3-D metasurfaces with optical possibilities
The new Sandia metamaterials can be fabricated in multiple layers to form complex, three-dimensional meta-atoms that reflect more light than shiny gold surfaces, usually considered the ultimate in infrared reflectivity. The III-V materials also emit photons when excited -- something that silicon, which can reflect, transmit and absorb -- can't do.

New material helps record data with light
Russian physicists with their colleagues from Europe through changing the light parameters, learned to generate quasiparticles -- excitons, which were fully controllable and also helped to record information at room temperature. These particles act as a transitional form between photons and electrons so the researchers believe that with excitons, they will be able to create compact optoelectronic devices for rapid recording and processing an optical signal. The study appeared in Advanced Materials.

New way to tune electronic energy levels may lead to valleytronic devices
Faster, more efficient data storage and computer logic systems could be on the horizon thanks to a new way of tuning electronic energy levels in two-dimensional films of crystal, discovered by researchers at MIT. The discovery could ultimately pave the way for the development of so-called "valleytronic" devices, which harness the way electrons gather around two equal energy states, known as valleys.

Conquering metal fatigue
Researchers have found a way to greatly reduce the effects of fatigue in steel by incorporating a laminated nanostructure into the material. The layered structuring gives the steel a kind of bone-like fracture-resistance, allowing it to endure cyclic stresses without allowing the spread of microcracks.

Sub-second system seizures
Fall 2016 brought a fundamental change to the United States. Its fastest and largest network -- the decentralized network of electronic market exchanges -- began to experience its first ever intentional delay. Specifically, a 38-mile coil of fiber-optic cable was embedded into a new exchange network node, which, given the finite speed of light, introduced a systematic 350-μs (microsecond) delay in signal transmission (1). The future impacts this might have at the systems level are unknown.

Chemists create molecular 'leaf' that collects and stores solar power without solar panels
An international research team centered at Indiana University have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide -- a carbon-neutral fuel source -- more efficiently than any other method of 'carbon reduction.' The discovery, reported today in the Journal of the American Chemical Society, is a new milestone in the quest to recycle carbon dioxide in the Earth's atmosphere into carbon-neutral fuels and others materials.

Small nanoparticles have surprisingly big effects on polymer nanocomposites
Polymer nanocomposites mix particles billionths of a meter in diameter with polymers, which are long molecular chains. Often used to make injection-molded products, they are common in automobiles, fire retardants, packaging materials, drug-delivery systems, medical devices, coatings, adhesives, sensors, membranes and consumer goods. When a team led by Oak Ridge National Laboratory tried to verify that shrinking the nanoparticle size would adversely affect the mechanical properties of polymer nanocomposites, they got a big surprise.

Phonon nanoengineering: Vibrations of nanoislands dissipate heat more effectively
Europium silicide has for some time attracted the attention of scientists. Recognized as being promising for electronics and spintronics, this material has recently been submitted by a team of physicists from Poland, Germany and France to comprehensive studies of the vibrations of its crystal lattice. The results yielded a surprise: deposited on a substrate of silicon, some structures of europium silicide appear to vibrate in a way that clearly broadens the possibilities of designing nanomaterials with tailored thermal properties.

Polymer-coated silicon nanosheets -- an alternative to graphene
Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Ultrafast detection of a cancer biomarker enabled by innovative nanobiodevice
Nagoya University-led researchers developed a nanobiodevice that can quickly and effectively separate microRNA, short lengths of ribonucleic acid present in bodily fluids, from mixtures of nucleic acids. The nanobiodevice contains a unique array of nanopillars that form a strong electric force under an applied electric field, allowing high-resolution separation of microRNA in less than 100 ms. Because microRNA is a biomarker for cancer, this technology may provide a simple, noninvasive approach for detecting cancer.

ORNL study examines tungsten in extreme environments to improve fusion materials
'We're trying to determine the fundamental behavior of plasma-facing materials with the goal of better understanding degradation mechanisms so we can engineer robust, new materials,' said materials scientist Chad Parish of Oak Ridge National Laboratory. He is senior author of a study in the journal Scientific Reports that explored degradation of tungsten under reactor-relevant conditions. Learning about how energetic atomic bombardment affects tungsten microscopically helps engineers improve nuclear materials.
