Domain engineered gallium oxide phototransistors enabling intelligent ultraviolet vision with dynamic gating

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
Single‐domain Si‐doped β‐Ga2O3 thin films grown on off‐axis sapphire eliminate domain boundaries, improving transport and photogating. Gate‐pulse modulation suppresses persistent photoconductivity, yielding ultrafast response and high detectivity. Integrated into a 24 × 24 array, the devices enable high frame rate DUV imaging and energy‐efficient ...

Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

open access: yesLaser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

open access: yesSmall, Volume 22, Issue 25, 4 May 2026.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...

Suspendable and Scalable Ultrasound‐Actuated ZnO‐Nanosheet‐Based Piezoelectric Microdevices for Wireless Electrical Stimulation of Cells

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
Silicon microtechnology enables the scalable fabrication of cytocompatible microdevices for wireless electrical stimulation. Microdevices smaller than a cell allow accurate interaction with single cells. By integrating piezoelectric nanostructures that can be actuated by ultrasound within the biomedical range, remote electrical cell stimulation is ...

Strategic materials and state capacity in Renaissance Italy: The economic policies of ‘Roman saltpetre’ procurement

open access: yesThe Economic History Review, Volume 79, Issue 2, Page 757-780, May 2026.
Abstract Demonstrating the existence of a soaring demand for strategic materials in fifteenth‐century Rome, the article pioneers research in the late medieval trade in saltpetre, the irreplaceable, rare component of gunpowder, indispensable for waging war following the diffusion of artillery technology.
