Protein‐Template Gold Nanoclusters Induce Differentiation and Modify the Functional Properties of Primary Astrocytes

Advanced NanoBiomed Research, Volume 6, Issue 5, May 2026.
The incubation of primary astrocytes with fAuNCs‐BSA induces: (A) long‐term effects including fAuNCs‐BSA internalization, red cell fluorescence, differentiation, upregulation of Ca2+ signaling, Cl‐current, and cell volume regulation. B) Short‐term (200 ms) stimulation with UV LED light increases in Ca2+ signaling and inhibition of K+ current. Astrocyte

Interactive Visualization of Diode Physics: Bridging the Fidelity‐Accessibility Gap in Web‐Based Engineering Education

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.

Patterning of Lead Halide Perovskite Device Stacks on CMOS Readout Using Selective Microfabrication Protocols

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 ...

Intrinsic and Water‐Triggered Hydrophilicity in Tween 20‐PDMS Composites for Dynamic and Long‐Term Wettability Control

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,
