Most MEMS are made primarily of silicon for reasons of convenience, but they wear out quickly due to friction and they are not biocompatible. Researchers at Argonne National Laboratory and a handful of other institutions around the world have directed their focus on ultrananocrystalline diamond (UNCD), which are smooth and wear-resistant diamond thin films. Recent work opens the door to using diamond for fabricating advanced MEMS devices.
Like the perfect sandwich, a perfectly engineered thin film for electronics requires not only the right ingredients, but also just the right thickness of each ingredient in the desired order, down to individual layers of atoms. In recent experiments Cornell Univ. researchers found a major difference between assembling atomically precise oxide films and the conventional layer-by-layer “sandwich making” of molecular beam epitaxy.
A group of scientists from South Korea have converted used-cigarette butts into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles and wind turbines to store energy.

With the help of ultracold quantum gas, physicists have achieved a 20-fold amplification of single-photon signals, a step that could aid all-optical data processing efforts. The breakthrough was made with the invention of a new type of optical transistor build from a cloud of rubidium atoms, held just above absolute zero, that is transparent to certain wavelengths of light.
The medical practice of Dr. Robert Howe, a reproductive endocrinologist in Massachusetts, introduced him to how computerized tomography could make precise 3-D images of body parts. As a student of music history, he realized the same technology could help him study delicate musical instruments from the past. With the help of engineers, these rare instruments are now being both imaged and printed printed in 3-D.
Scientists at Northwestern Univ. have developed a new technique for creating non-equilibrium systems, which experience constant changes in energy and phases, such as temperature fluctuations, freezing and melting, or movement. The method, which involves injecting energy through oscillations to force particles to self-assemble under non-equilibrium conditions, should help us understand the fundamentals of this mysterious topic.
MIT Lincoln Laboratory spinout TeraDiode is commercializing a multi-kilowatt diode laser system that’s bright enough to cut and weld through a half-inch of steel, and at greater efficiencies than today’s industrial lasers. The new system is based on a wavelength beam-combining laser diode design that won an R&D 100 Award in 2012. It combines multiple beams into a single output ray, allowing for a power boost without efficiency loss.

Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single handedly. Now a new wrist-mounted robot can provide a helping hand—or rather, fingers. Researchers at Massachusetts Institute of Technology have developed a robot that enhances the grasping motion of the human hand.
Long dismissed as too impractical and expensive for everyday cars, fuel cell technology is getting a push into the mainstream by Toyota, the world's top-selling automaker. Buoyed by its success with electric-gasoline hybrid vehicles, Toyota is betting that drivers will embrace hydrogen fuel cells, an even cleaner technology. The company’s fuel cell car will go on sale before April next year.
Scientists in Belgium have recently fabricated the world’s first randomly deformable optical waveguide. This innovative optical link remains functional for bending radii down to 7 mm, and can be stretched to more than a third of its length. A link like this can be used to interconnect optical components within a stretchable system, just like stretchable electrical interconnections.
A team including scientists from Spain and from IBM Research in Switzerland have published work which describes an extremely simple method to obtain high quality nanographenes from easily available organic compounds. This method is based on the reactivity of a group of molecules named arynes, which can act as "molecular glue" to paste graphene fragments together.
The doubling of transistors on a microprocessor occurs roughly every two years, and is the outcome of what is called Moore’s Law. In a bid to continue this trend of decreasing transistor size and increasing computation and energy efficiency, chip-maker Intel has partnered with Lawrence Berkeley National Laboratory to design an entirely new kind of photoresist, one that combines the best features of two existing types of resist.
The next big thing in aviation may be really small. With some no bigger than a hummingbird, the hottest things at this week's Farnborough International Airshow are tiny compared with the titans of the sky, such as the Airbus 380 or the Boeing Dreamliner.
Together with teams from Finland and Japan, physicists from the Univ. of Basel in Switzerland were able to place 20 single bromine atoms on a fully insulated surface at room temperature to form the smallest “Swiss cross” ever created.
