Chemical treatment improves quantum dot lasers
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research at Los Alamos National Laboratory's Nanotech Team, the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.

Major advance in nanopore detection of peptides and proteins
Nanopore technology, which is used to sequence DNA, is cheap, hand-held and works in the jungle and in space. The use of this technology to identify peptides or proteins is now a step closer. University of Groningen scientists have used a patented nanopore to identify the fingerprints of proteins and peptides, and it can even detect polypeptides differing by one amino acid. The results were published on 16 October in the journal Nature Communications.

Rice U. study: Vibrating nanoparticles interact
Like a tuning fork struck with a mallet, tiny gold nanodisks can be made to vibrate at resonant frequencies when struck by light. In new research this week, Rice University chemist Stephan Link and colleagues showed how to selectively alter those vibrational frequencies by gathering different-sized nanodisks into groups.

Spin current detection in quantum materials unlocks potential for alternative electronics
A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. A team of scientists has developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.

New materials may provide better ways to capture and store solar energy
Researchers at Worcester Polytechnic Institute (WPI), funded by two significant National Science Foundation grants and an award from the Massachusetts Clean Energy Center, are exploring new materials for solar cells that could boost their efficiency and make them less expensive to manufacture, and are developing new photocatalysts that may lower the cost of producing hydrogen using solar electricity (generating hydrogen with electrolysis could be an effective way to store solar energy until it is needed).

On the road to fire-free, lithium-ion batteries made with asphalt
Lithium-ion batteries can be found in everything from cell phones to hoverboards, but these power sources have recently made headlines for the fires they have inadvertently caused. To address these safety hazards, scientists report in ACS Nano that they are paving the way to better batteries with a naturally occurring form of asphalt.

Morphologies of porous MoS2 show good performance in hydrogenation of phenol
Two morphologies of porous MoS2 obtained by using thiourea and L-cysteine as sulfur sources and modified SiO2 nanoparticles as hard templates,The method offers the advantages of simple steps, convenient operation, controllable pore size, and a specific surface area. MoS2 nano-materials with the respective morphologies were used to catalyze the hydrodeoxygenation (HDO) reaction, showing a good performance in hydrogenation of phenol.

Forget about it
Inspired by human forgetfulness -- how our brains discard unnecessary data to make room for new information -- scientists at the US Department of Energy's (DOE) Argonne National Laboratory, in collaboration with Brookhaven National Laboratory and three universities, conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually 'forgets.' This could one day be used for advanced bio-inspired computing.

Machine learning translates 'hidden' information to reveal chemistry in action
Scientists have developed a new way to capture the details of chemistry choreography as it happens. The method -- which relies on computers that have learned to recognize hidden signs of the steps -- should help them improve the performance of catalysts to drive reactions toward desired products faster.

Breath instead of a blood test
Blow into the tube, please. In the future, the procedure will not just be used by police checking for alcohol intoxication, but also for testing the condition of athletes and for people who want to lose that extra bit of weight. A sensor developed by ETH researchers makes it possible to measure when the body starts burning fat with a convenient breathalyser.

Spin-current generation gets mid-IR boost with plasmonic metamaterial
Researchers have begun to use metamaterials, engineered composites that have unique properties not found in nature, to enhance the absorption rates of plasmonic absorbers, and a team in Japan used a trilayered metamaterial to develop a wavelength-selective plasmonic metamaterial absorber on top of a spintronic device to enhance the generation of spin currents from the heat produced in the mid-infrared regime. The research is reported this week in APL Photonics.

Prototype shows how tiny photodetectors can double their efficiency
UC Riverside physicists have developed a photodetector -- a device that converts light into electrons -- by combining two distinct inorganic materials and producing quantum mechanical processes that could revolutionize the way solar energy is collected. The researchers stacked two atomic layers of tungsten diselenide on a single atomic layer of molybdenum diselenide. Such stacking results in properties vastly different from those of the parent layers, allowing for customized electronic engineering at the tiniest possible scale.

A zero-index waveguide
In 2015, Harvard researchers developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase of light could be stretched infinitely long. The metamaterial represented a new method to manipulate light and was an important step forward for integrated photonic circuits. Now, Harvard researchers have developed a zero-index waveguide compatible with current silicon photonic technologies. In doing so, the team observed a physical phenomenon that is usually unobservable -- a standing wave of light.

Silicon is liberated from Abbot's Flatland
'There is plenty of room at the bottom'. This is often quoted to highlight the value of available space that comes with miniaturization. Due to the amazing successes of modern fabrication techniques, one is surprised to hear that vast space below the surface, inside silicon, is not used. What more could be achieved, if the rest of the chip was opened to usage? Scientists now demonstrate such devices, published in latest issue of Nature Photonics.

Columbia researchers observe exotic quantum particle in bilayer graphene
A Columbia team has definitively observed an intensely studied anomaly in condensed matter physics--the even-denominator fractional quantum Hall state--via transport measurement in bilayer graphene. 'Observing the 5/2 state in any system is a remarkable scientific opportunity, since it encompasses some of the most perplexing concepts in modern condensed matter physics, such as emergence, quasi-particle formation, quantization, and even superconductivity ...[It may have] great potential for real-world applications, particularly in quantum computing.'
