Smaller, cheaper integrated photonics Researchers from the University of California Santa Barbara, California Institute of Technology (Caltech), and Ecole Polytechnique Fédérale de Lausanne (EPFL) developed a way to integrate an optical frequency comb on a silicon photonic chip. Optical frequency combs are collections of equally spaced frequencies of laser light (so called because when pl... » read more

Capturing waste heat Researchers at Wuhan University and University of California Los Angeles developed a hydrogel that can both cool down electronics and convert the waste heat into electricity. The thermogalvanic hydrogel consists of a polyacrylamide framework infused with water and specific ions. When they heated the hydrogel, two of the ions (ferricyanide and ferrocyanide) transferred e... » read more

Maskless EUV lithography At this week’s 2020 EUVL Workshop, KJ Innovation will present more details about its efforts to develop a maskless extreme ultraviolet (EUV) lithography technology. Still in R&D, KJ Innovation’s maskless EUV technology involves a high-numerical aperture (high-NA) system with 2 million individual write beams. The 0.55 NA technology is targeted for direct-write l... » read more

Complex microparticles A team of researchers have developed the world’s most complex microparticle. In the lab, researchers have assembled hierarchically organized particles with twisted spikes and polydisperse Au-Cys (gold-cysteine) nanoplatelets or nanosheets. The sheets all twist in the same direction. Cysteine is a proteinogenic amino acid. The structure is said to be more complex ... » read more

Fast photography The California Institute of Technology has developed a high-speed camera that can take pictures of transparent objects. The technology, called phase-sensitive compressed ultrafast photography (pCUP), can take up to 1 trillion pictures per second of transparent objects. Potentially, the technology from Caltech could be used in several applications, such as taking photos of s... » read more

DNA programming Computer scientists at California Institute of Technology, University of California, Davis, Maynooth University, and Harvard University created a library of DNA molecules that can self-assemble to compute a variety of algorithms. Each molecule represents a six-bit binary number. The library created by the team is made up of around 700 short pieces, or tiles, of DNA. Each DNA... » read more

World’s smallest gyroscope The California Institute of Technology has developed the world's smallest optical gyroscope. The gyroscope is 500 times smaller than current devices, but it can detect phase shifts that are 30 times smaller than today’s systems. [caption id="attachment_24139584" align="alignleft" width="300"] The new optical gyroscope—shown here with grains of rice—is 5... » read more

World’s fastest camera The Institut national de la recherche scientifique (INRS) in Canada has developed what researchers say is the world’s fastest camera. The camera, called T-CUP, is capable of capturing ten trillion frames per second. It’s possible to nearly freeze time to see various phenomena in the system. In a system, the technology can be used to take high-speed images of sam... » read more

Wireless charging Engineers at the University of Washington developed a method to safely charge a smartphone wirelessly using a laser, potentially as quickly as a standard USB cable. Safety features of the system include a reflector-based mechanism to shut off the laser and heatsinks. The charging beam is generated by a laser emitter that the team configured to produce a focused beam in the... » read more
