Optothermal nanotweezers are an innovative optical design method that has revolutionized classical optical techniques to capture a broad range of nanoparticles. While the optothermal temperature field can be employed for in situ regulation of nanoparticles, challenges remain in identifying their potential for regulating bionanoparticles. /news/2023-11-crispr-powered-optothermal-nanotweezers.html Bio & Medicine Nanophysics Mon, 27 Nov 2023 09:59:01 EST news620301538 The fundamental rotation of micro and nano-objects is crucial for the functionality of micro and nanorobotics, as well as three-dimensional imaging and lab-on-a-chip systems. These optical rotation methods can function fuel-free and remotely, and are therefore better suited for experiments, while current methods require laser beams with designed intensity profiles or objects with sophisticated shapes. These requirements are challenging for simpler optical setups with light-driven rotation of a variety of objects, including biological cells. /news/2022-07-universal-optothermal-micronanoscale-rotors.html Optics & Photonics Fri, 01 Jul 2022 10:30:02 EDT news575887678 While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design complexity, the laser beams traditionally used in metal printing have drawbacks that can lead to defects and poor mechanical performance. /news/2021-09-laser-metal-3d.html General 糖心视频ics Optics & Photonics Wed, 22 Sep 2021 11:02:08 EDT news551527324 New research by scientists from Delft University of Technology and the University of Duisburg-Essen uses the motion of atomically thin graphene to identify noble gasses. These gasses are chemically passive and do not react with other materials, which makes it challenging to detect them. The findings are reported in the journal Nature Communications. /news/2020-11-graphene-balloons-noble-gases.html Nanophysics Nanomaterials Fri, 27 Nov 2020 12:50:03 EST news525701694 In a recent report, Xiaolei Peng and a team of scientists in materials science and engineering at the University of Texas, U.S., and the Tsinghua University, China, developed opto-thermoelectric microswimmers bioinspired by the motion behaviors of Escherichia coli (E. coli). They engineered the microswimmers using dielectric gold Janus particles driven by a self-sustained electric field arising from the optothermal response of the particles. When they illuminated the constructs with a laser beam, the Janus particles showed an optically generated temperature gradient along the particle surfaces, forming an opto-thermoelectrical field to propel themselves along. /news/2020-09-opto-thermoelectric-microswimmers.html General 糖心视频ics Optics & Photonics Fri, 04 Sep 2020 13:10:01 EDT news518442238 Oscillating flow and light pulses can be used to create reconfigurable architecture in liquid crystals. Materials scientists can carefully engineer concerted microfluidic flows and localized optothermal fields to achieve control on nucleation , growth and shape of such liquid domains. In comparison, pure liquids in thermodynamic equilibrium are structurally homogeneous. Experimental work based on theory and simulations have shown that if the liquids are maintained in a controlled state of nonequilibrium, the resulting structures can be indefinitely stabilized. /news/2019-02-sculpting-stable-pure-liquids.html General 糖心视频ics Soft Matter Thu, 21 Feb 2019 09:30:06 EST news469873756 (糖心视频) 鈥擜 team of engineering and physics researchers with members from the U.S., the U.K. and the Republic of Muldova has found that covering a common type of plastic with a graphene coating can increase its conductivity by up to 600 times.

Already prized for its extraordinary ability to change size, shape and physical identity, vanadium dioxide can now add muscle power to its attributes. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length within 60 milliseconds 鈥� faster than the blink of an eye. /news/2013-12-powerful-microscale-torsional-musclemotor-vanadium.html Materials Science Thu, 19 Dec 2013 16:49:57 EST news306694184 A University of California, Riverside engineering professor and a team of researchers have made a breakthrough discovery with graphene, a material that could play a major role in keeping laptops and other electronic devices from overheating. /news/2012-01-electronics-cool-graphene-impacts-dissipation.html Nanomaterials Mon, 09 Jan 2012 09:16:54 EST news245322976
