The Feasibility Test of Electric Propulsion Systems: Case Study for a Light and Fixed‐Wing Aircraft
Energy Science &Engineering, EarlyView.ABSTRACT This study investigates the feasibility and performance of a fully electric propulsion system (EPS) integrated into a light fixed‐wing aircraft. The system consists of a 65 kW‐class electric motor, a high‐efficiency inverter, and dual lithium‐ion battery packs with a total capacity of 27 kWh—collectively engineered to fulfill both power ...

Energy Science &Engineering, EarlyView.Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

Chiral perovskites for next‐generation chiral optoelectronics and spintronics
FlexMat, EarlyView.Benefiting from structural inversion symmetry breaking and strong spin‐orbit coupling, chiral perovskites possess intriguing chiral optical and spin properties. We overview their advances and core applications in perovskite solar cells, circularly polarized light detectors and spin circularly polarized‐light‐emitting diodes, offering great potential ...

Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials
Interdisciplinary Materials, EarlyView.Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.
