Transistor-inspired ultra-sensitive materials heat up advanced data security

Nanowerk  September 26, 2023 Researchers in China proposed a novel strategy for constructing highly sensitive TFMs with tunable emission (450–650 nm) toward multilevel information encryption which employs polarity-sensitive fluorophores with donor–acceptor–donor (D–A–D) type structures as emitters and long-chain alkanes as thermosensitive loading matrixes. The structure–function relationships between the performance of TFMs and the structures of both fluorescent emitters and phase-change molecules were systematically studied. The TFMs exhibited over 9500-fold fluorescence enhancement toward the temperature change, as well as ultrahigh relative temperature sensitivity up to 80% K−1, which were confirmed. The TFMs could be further developed as information-storage platforms within a […]

Smart chip senses, stores, computes and secures data in one low-power platform

Nanowerk  July 30, 2022 Modern software cryptosystems require extensive computational infrastructure for implementing ciphering algorithms, making them difficult to be adopted by IoT edge sensors that operate with limited hardware resources and at low energy budgets. Researchers at the State University of Pennsylvania proposed and experimentally demonstrated an “all-in-one” 8 × 8 array of robust, low-power, and bio-inspired crypto engines monolithically integrated with IoT edge sensors based on 2D memtransistors. Each engine comprises five 2D memtransistors to accomplish sensing and encoding functionalities. They showed that the ciphered information is secure from an eavesdropper with finite resources and access to deep […]

NIH issues a seismic mandate: share data publicly

Nature  February 16, 2022 In January 2023, the US National Institutes of Health (NIH) will begin requiring most of the 300,000 researchers and 2,500 institutions it funds annually to include a data-management plan in their grant applications — and to eventually make their data publicly available. Under the new policy, which will go into effect on 25 January, all NIH grant applications for projects that collect scientific data must include a ‘data management and sharing’ (DMS) plan that contains details about the software or tools needed to analyse the data, when and where the raw data will be published and […]
