Ultrashort-Pulse Laser Could Solve Dilemma of Nuclear Waste Disposal
Researchers in Lithuania have developed an ultrashort-pulse laser that could eradicate nuclear waste and decrease the decay period from tens of thousands of years to seconds, hours, or months, depending on the material, they said. The Single Cycle Femtosecond high-intensity laser system (SYLOS) is a high-intensity, ultrashort-pulse laser that has the potential to solve the nuclear waste management problem.

New Technique Retrieves Color Images from Scattered Light
Engineers at Duke University have developed a method for extracting a color image from a single exposure of light scattered through a mostly opaque material. The new approach overcomes the limitations of conventional optical memory effect techniques in the realm of color, by using spectral coding and compressed sensing to achieve snapshot color imaging through scattering media.

Sending Quantum Information Securely from Laser Light to a Quantum Dot
Scientists from Osaka University have demonstrated how information encoded in the circular polarization of a laser beam can be translated into the spin state of an electron in a quantum dot (QD). They used laser light to send quantum information to a QD by altering the spin state of a single electron trapped on the QD.

Canon Surface Reflectance Analyzer
Canon U.S.A. Inc., Industrial Products Div.
Canon RA-532H, Surface Reflectance Analyzer (goniophotometer), is a compact, portable device capable of measuring 4 surface appearance conditions in a single pass: Gloss, Haze, Image Clarity (IC), and BRDF (Bidirectional Reflectance Distribution Function). Additionally, Canon has released its own new parameter, “Scattering” parameter, overcoming the shortage of both IC and DOI (Distinctiveness of Image) when evaluating matte and textured surfaces as well as orange peel surface.

Flexible Sputtered Coatings
Deposition Sciences Inc. (DSI)
Roll-to-roll processes present a number of challenges when coating flexible surfaces, including unbalanced stress on each side of the substrate and limited line speed. These limitations affect the thickness and possibility of complex coatings. To address these challenges, DSI developed their batch coating technology, MicroDyn®. This unique process utilizes a proprietary magnetron sputtering chamber that was custom designed to address the challenges of high throughput coating.

Multiphoton Microscopy Uncovers the Architecture of Collagen and Elastic Fibers
Using multiphoton microscopy (MPM), researchers at Kyoto University showed that the collagen fibers in the skin are arranged in a mesh-like lattice and not in a clear geometric orientation as previously thought. They further found that the connective tissue in the skin, known as elastic fibers, is arranged in the same way as the collagen.

Natural-Scale Snail Robot Is Powered by Light
A soft snail robot, developed by a team at the University of Warsaw with colleagues from Xi'an Jiaotong-Liverpool University, is capable of mimicking the adhesive locomotion of snails and slugs on a natural scale. The bioinspired robot is made from liquid crystalline elastomer (LCE), a smart material that can change its shape under different stimuli, including illumination with visible light.
