Crystal unclear: Why might this uncanny crystal change laser design?
New research suggests that the relatively large crystals used to change several properties of light in lasers -- changes that are crucial for making lasers into practical tools -- might be created by stacking up far smaller, rod-shaped microcrystals that can be grown easily and cheaply.

Nanocatalysis for organic chemistry
Nanocatalysis has attracted much attention in the past few years. Functionalized materials with a nano-/submicro-dimension display a significant and dramatically powerful catalytic capability than traditional catalysts in organic chemical reactions due to the increased surface area which they provide and multiple catalytic centers in their structures.

Electrons at the speed limit
Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Researchers at ETH Zurich have now investigated how fast electrons can ultimately be controlled with electric fields. Their insights are of importance for the petahertz electronics of the future.

Important advance made with new approach to 'control' cancer, not eliminate it
Researchers have created a new drug delivery system that could improve the effectiveness of an emerging concept in cancer treatment -- to dramatically slow and control tumors on a long-term, sustained basis, not necessarily aiming for their complete elimination.

Forces of nature: Interview with microscopy innovators Gerd Binnig and Christoph Gerber
The inventors of one of the most versatile tools in modern science -- the atomic force microscope, or AFM -- tell their story in an interview published online this week. The AFM was invented in the mid 1980s by Gerd Binnig, Christoph Gerber and Calvin Quate, three physicists who are sharing the 2016 Kavli Prize in Nanoscience.

A promising route to the scalable production of highly crystalline graphene films
Researchers discovered a procedure to restore defective graphene oxide structures that cause the material to display low carrier mobility. By applying a high-temperature reduction treatment in an ethanol environment, defective structures were restored, leading to the formation of a highly crystalline graphene film with excellent band-like transport. These findings are expected to come into use in scalable production techniques of highly crystalline graphene films.

New electrical energy storage material shows its power
A new material developed by Northwestern University chemist William Dichtel and his team could one day speed up the charging process of electric cars and help increase their driving range. The modified covalent organic framework (COF) material combines the ability to store large amounts of electrical energy or charge, like a battery, and the ability to charge and discharge rapidly, like a supercapacitor, into one device. The researchers built a prototype device capable of powering an LED for 30 seconds.

50 years after the release of the film 'Fantastic Voyage,' science upstages fiction
Fifty years to the day after the film 'Fantastic Voyage' was first shown in theaters, the Polytechnique Montréal Nanorobotics Laboratory is unveiling a unique medical interventional infrastructure devoted to the fight against cancer. The outcome of 15 years of research conducted by Professor Sylvain Martel and his team, it enables microscopic nanorobotic agents to be guided through the vascular systems of living bodies, delivering drugs to targeted areas.

Bio-inspired tire design: Where the rubber meets the road
Anand Jagota, professor of chemical and biomolecular engineering and director of Lehigh's bioengineering program, and his team recently published a paper in Scientific Reports outlining their work creating new bio-inspired film-terminated structures with unique friction characteristics that could have positive industrial implications for, among other things, tires. The paper was co-written by Jagota and lead author Zhenping He along with Ying Bai, Chung-Yuen Hui of Cornell University and Benjamin Levrard, a researcher at Michelin Corporation.

Lehigh engineer discovers a high-speed nano-avalanche
Doctoral student Charles McLaren and Professor Himanshu Jain from Lehigh University -- along with colleagues at the University of Marburg in Germany -- have published new findings in the September 2016 issue of the Journal of Electrochemical Society about the process involving transformations in glass that occur under intense electrical and thermal conditions. New understanding of these mechanisms could lead the way to more energy-efficient glass manufacturing, and even glass supercapacitors that leapfrog the performance of batteries now used for electric cars and solar energy.

Silicon nanoparticles trained to juggle light
Silicon nanoparticles based devices would allow to transmit, reflect, or scatter incident light in a specified direction, depending on its intensity. They could be integrated into microchips that would enable ultrafast all-optical signal processing in optical communication lines and the next generation optical computers.

Analog DNA circuit does math in a test tube
Duke University researchers have created strands of synthetic DNA that, when mixed together in a test tube in the right concentrations, form an analog circuit that can add, subtract and multiply as the molecules form and break bonds. While most DNA circuits are digital, their device performs calculations in an analog fashion by measuring the varying concentrations of specific DNA molecules directly, without requiring special circuitry to convert them to zeroes and ones first.

Nanofiber scaffolds demonstrate new features in the behavior of stem and cancer cells
A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.

Nanofur for oil spill cleanup
Some water ferns can absorb large volumes of oil within a short time, because their leaves are strongly water-repellent and, at the same time, highly oil-absorbing. Researchers of KIT, together with colleagues of Bonn University, have found that the oil-binding capacity of the water plant results from the hairy microstructure of its leaves. It is now used as a model to further develop the new Nanofur material for the environmentally friendly cleanup of oil spills.

Stretchy supercapacitors power wearable electronics
A future of soft robots or smart T-shirts may depend on the development of stretchy power sources. But traditional batteries are thick and rigid -- not ideal properties for materials that would be used in tiny malleable devices. In a step toward wearable electronics, a team of researchers has produced a stretchy micro-supercapacitor using ribbons of graphene. The researchers present their work at the 252nd National Meeting & Exposition of the American Chemical Society.

Natural scale caterpillar soft robot is powered and controlled with light
Researchers at the Faculty of Physics at the University of Warsaw, using the liquid crystal elastomer technology, originally developed in the LENS Institute in Florence, demonstrated a bioinspired micro-robot capable of mimicking caterpillar gaits in natural scale. The 15-millimeter long soft robot harvests energy from green light and is controlled by spatially modulated laser beam. Apart from traveling on flat surfaces, it can also climb slopes, squeeze through narrow slits and transport loads.
