Exploring the Structural, Electronic, and Optical Characteristics of ZrSnO3 Through First‐Principles Calculations for Optoelectronics and Photocatalytic Applications

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT We performed first‐principles density functional theory calculations to methodically analyse the structural, mechanical, electronic, thermal, and optical properties of trigonal ZrSnO3 under external pressure up to 60 GPa with GGA‐PBE and HSE06 functionals.

A hybrid deep learning framework for real‐time speckle reduction and image enhancement on portable ultrasound systems

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Speckle patterns in ultrasound images often obscure anatomical details, leading to diagnostic uncertainty. Recently, various deep learning‐based techniques have been introduced to effectively suppress speckle; however, their high computational costs pose challenges for low‐resource devices, such as portable ultrasound systems ...

First‐Principle Analysis of the Structural, Elastic, Electronic, and Optical Properties of Novel AHgF3 (A = K and Fr) Perovskite

Nano Select, Volume 7, Issue 8, August 2026.
The evaluation of the physical properties of novel KHgF3 and FrHgF3 perovskites is explored. Both compounds are thermodynamically stable and mechanically ductile. Featuring narrow band gaps around 0.53–0.60 eV, these materials show strong potential for use in flexible infrared‐to‐visible optoelectronics and energy conversion devices.

Optoelectronics of Single Mixed Dislocations in Van Der Waals Core‐Shell Nanowires

Small, Volume 22, Issue 44, 7 August 2026.
Ge1‐xSnxS van der Waals core‐shell nanowires can host single helical dislocations whose character is tunable from a pure screw to a majority edge dislocation via the core‐shell lattice mismatch. Cathodoluminescence shows profound effects once an edge component is introduced, notably a lowering of the spontaneous emission quantum efficiency due to the ...
