Many crystals exhibit polymorphism, undergoing atomic rearrangements that result in unit cells belonging to different symmetry groups. These structural changes directly affect lattice vibration modes and consequently influence their mid-infrared optical properties. In this study, we use tungsten tr…

Semi-metallic noble-metal dichalcogenides are promising materials for infrared optoelectronics, yet the origin and tunability of their nonlinear optical responses remain poorly understood. Here, we demonstrate in-situ mechanical control of photon-drag photocurrents in polycrystalline PtSe$_2$ thin…

We present VIBE-QC, a general-purpose open-source electronic-structure code for molecules and solids, developed almost entirely through generative-AI-assisted programming (“vibe-coding”) under expert human direction. The molecular stack provides Hartree–Fock and Kohn–Sham DFT over the full LIBXC li…

Fluorescence blinking, often regarded as a limitation for stable emitters, can enable super-resolution localization microscopy and serve as a versatile reporter of the photophysical states of quantum emitters and their interactions with local environment. However, conventional blinking emitters are…

Materials that can switch between low and high thermal conductivity states enable on-demand management of temperature and heat flow, which will advance the application of solid-state refrigeration, energy conversion, and thermal circuits. Here, we report a large thermal conductivity on/off ratio of…

Lignocellulosic residues are non-cost, non-edible, renewable feedstocks that can be used in polyhydroxybutyrate (PHB) production. PHB is a bioplastic synthetized by microorganisms, formed intracellularly under stressful growth conditions; however, its production costs are high, representing the maj…

Experiments have revealed that collective strong coupling in optical cavities can drastically alter the conductivity and dielectric properties of molecular ensembles, or even trigger abrupt phase transitions (in Rayleigh scattering or dispersion force driven conformational equilibrium). Until now,…

Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low effic…

The optical characterization of atomic-layer materials requires the quantitative determination of both their complex refractive indices (RIs) and thickness. However, existing methods rely on preset thicknesses, empirical models, or auxiliary characterization tools. It remains a challenge to jointly…
