Team develops transistors with sliding ferroelectricity based on polarity-switchable molybdenum disulfide
Credit: Yang et al. (Nature Electronics, 2023). Over the past few years, engineers have been trying to devise alternative hardware designs that would allow a single device to both perform computations and store data. These emerging electronics, known as computing-in-memory devices, could have numerous advantages, including faster speeds and enhanced data analysis capabilities. To store…

Unimolecular self-assembled hemicyanine-oleic acid conjugate acts to eliminate cancer stem cells: Study
Schematic illustration of unimolecular self-assembled CyOA NPs enhanced phototoxicity to CSCs by implementing oxygen-economical PDT. Credit: Research Cancer stem cells (CSCs) are a rare population of cells in tumor tissues that drive tumorigenesis, recurrence, and metastasis. Therefore, the development of anti-tumor therapies that can eliminate CSCs has significant implications for cancer treatment. Photodynamic therapy (PDT)…

Quantum Computing’s Hard, Cold Reality Check
The quantum computer revolution may be further off and more limited than many have been led to believe. That’s the message coming from a small but vocal set of prominent skeptics in and around the emerging quantum computing industry. Quantum computers have been touted as a solution to a wide range of problems, including financial…

Chips to Compute With Encrypted Data Are Coming
Trust no one. It’s not just a throwaway line from TV thrillers. It’s becoming the goal of computer security, and a technology that can make it a reality has arrived. Called fully homomorphic encryption, or FHE, it allows software to compute on encrypted data without ever decrypting it. The possibilities are enormous: huge leaps in…

Researchers develop all-optical switches that could lead to faster computer processors
Dec 22, 2023 (Nanowerk News) Conventional computer processors have pretty much maxed out their “clock speeds” — a measurement of how fast they can toggle on and off — due to limitations of electronic switching. Scientists looking to make improvements in computer processors have become intrigued by the potential of all-optical switching, which uses light…
