Electrically driven chiral emission from plasmonic tunnel junctions

Chirality plays a crucial role in a broad range of processes, including light-matter interactions in physics, chemistry, and biology, while quantum tunneling provides a promising mechanism for light generation at the nanoscale. By integrating tunnel junctions with chiral plasmoni...

Distilling First-Principles Accuracy into Compact Machine Learning Potentials for Condensed-Phase Chemistry

Abstract Accurate machine learning interatomic potentials (MLIPs) have made first-principles-quality potential energy surfaces increasingly accessible for condensed-phase chemistry, but their inference cost can still limit the sampling needed to compute experimentally relevant ob...

A Two-Step Synthesis of Covalent Genetically Encoded Libraries of Peptide-Derived Macrocycles Enables the Use of Electrophiles with Diverse Reactivity

Abstract Genetically encoded libraries of peptide-derived macrocycles containing electrophile “warheads” (cGELs) can be used to identify potent and selective covalent ligands for protein targets. Such cGELs are synthesized either by incorporation of unnatural amino acids that dis...

Improving the accuracy of fixed-node diffusion Monte Carlo for non-covalent interactions

Diffusion quantum Monte Carlo (DMC) and coupled cluster theory [CCSD(T)] are widely used benchmark methods for noncovalent interactions (NCIs). However, recent studies have reported notable discrepancies for several hydrogen-bonded and dispersion-dominated systems, raising questi...

Few-shot neuromorphic vision in a nonlinear photonic network laser

With the growing prevalence of artificial intelligence (AI), demand increases for hardware that mimics the brain’s ability to extract structure from limited data. In the retina, ganglion cells detect features from sparse inputs via lateral inhibition, where neurons antagonistical...

Interfacial Electronic Regulation of GO/Na0.5Bi2.5Nb2O9 Aurivillius-Layered Perovskite Heterointerfaces for Enhanced Photocatalysis

Constructing heterointerfaces between semiconductor photocatalysts and carbonaceous materials is an effective strategy for enhancing photocatalytic performance. However, the role of graphene oxide (GO) in modulating the interfacial electronic properties of Aurivillius-layered per...

Modeling of Diamond Trench Metal Oxide Semiconductor Barrier Schottky Rectifier Based on Dynamic Reverse Bias Simulation Framework

This work presents an electrothermal optimization study of diamond‐based trench metal oxide semiconductor (MOS) barrier Schottky (TMBS) rectifiers using mixed‐mode drift‐diffusion technology computer aided design simulations under quasi‐static and dynamic reverse‐bias conditions....
