Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.ABSTRACT In engineering education, a “fidelity‐accessibility trade‐off” persists: accessible web simulations often lack physical accuracy, while complex industrial tools impose heavy cognitive loads. This hinders effective instruction in semiconductor physics in remote, hardware‐constrained environments.

Advanced Materials, Volume 38, Issue 21, 13 April 2026.We present a microfabrication and integration strategy for lead halide perovskite photodetectors on electronic readouts. Standard photolithography, aqueous processing, selective transparent electrode etching, and plasma‐assisted pixel isolation enable precise monolithic integration of patterned 400 × 400 perovskite microphotodetector arrays on a CMOS ...

Optimization of Energy Efficiency in Photovoltaic Water Pumping Systems Using Neural Networks
Energy Science &Engineering, Volume 14, Issue 4, Page 2153-2181, April 2026.This study investigates an optimal control strategy for a photovoltaic (PV) water pumping system aimed at improving efficiency and autonomy in off‐grid applications. The system uses an induction motor with direct torque control and compares three maximum power point tracking (MPPT) techniques: neural network–based MPPT, Incremental Conductance (IC ...

Small, Volume 22, Issue 24, 27 April 2026.A one‐step bulk integration of the surfactant Tween 20 into PDMS enables intrinsic and water‐triggered hydrophilicity. Combined molecular simulations and experiments reveal a dual mechanism where bound and mobile Tween 20 molecules cooperatively induce self‐activating, stretch‐tolerant, and long‐term wettability, supporting self‐driven liquid transport,

Radio Science, Volume 61, Issue 4, April 2026.Abstract A novel switch‐based Active‐Neutral‐Clamped (ANPC) inverter for low DC‐link voltage is presented in this paper. The proposed ANPC topology minimizes switches and achieves 1.5 times better voltage gain than standard inverters. The main objective of this design is to reduce active switches in the inverter to increase system efficiency.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
Advanced Materials, Volume 38, Issue 16, 17 March 2026.This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.
