In a new report on Science Advances, Su Xu and colleagues in engineering, nanotechnology, nanobionics and quantum information in China were inspired by the natural ecological relationship between transparent oceanic animals and their predators that employ a cross-wavelength detection strategy. The scientists proposed a new concept of cross-wavelength invisibility that integrated a variety of invisibility tactics. They presented a Boolean metamaterial design strategy to balance divergent material requirements across cross-scale wavelengths. As proof of concept, they simultaneously demonstrated longwave cloaking and shortwave transparency using a nanoimprinting technique. The work extended stealth techniques from individual strategies of invisibility targeting a single-wavelength spectrum to integrated invisibility targeting cross-wavelength applications. These experiments will pave the way to develop cross-wavelength integrated metadevices. /news/2020-09-invisibility-cross-wavelength-tactics.html General 糖心视频ics Optics & Photonics Wed, 30 Sep 2020 10:10:50 EDT news520679446 Scalable nanoparticle-based computing architectures have several limitations that can severely compromise the use of nanoparticles to manipulate and process information through molecular computing schemes. The von Neumann architecture (VNA) underlies the operations of multiple arbitrary molecular logic operations in a single chip without rewiring the device. In a new report, Sungi Kim and a team of scientists at the Seoul National University in South Korea developed the nanoparticle-based VNA (NVNA) on a lipid chip.

The nanoparticle-based von Neuman architecture (NVNA) allowed a group of nanoparticles to form a feed-forward neural network known as a perceptron (a type of artificial neural network). The system can implement functionally complete Boolean logical operations to provide a programmable, resettable and scalable computing architecture and circuit board to form nanoparticle neural networks and make logical decisions. The work is now published on Science Advances. /news/2020-09-nanoparticle-based-architecture-nanoparticle-neural-networks.html Nanophysics Wed, 02 Sep 2020 10:20:01 EDT news518259993 The Sensitivity Conjecture has stood as one of the most important, and baffling, open problems in theoretical computer science for nearly three decades.

In a recent study published in Science Advances, Jinyoung Seo and co-workers in the Department of Chemistry at Seoul National University in South Korea, reported on a nanoparticle platform built in with logic gates and circuits at the level of the single particle. They implemented the platform on a supporting lipid bilayer. Inspired by cellular membranes in biology that compartmentalize and control signaling networks, the scientists called the platform "lipid nanotablet" (LNT).
