A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, EarlyView.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Advanced Science, EarlyView.This study presents a femtosecond laser‐based ultrashort pulse dicing system that uses a non‐diffracting Bessel beam to shape the femtosecond laser. The use of femtosecond Bessel beam shaping and high‐speed scanning enables rapid material removal that outpaces thermal diffusion, thereby suppressing melting, minimizing the HAZ, and reducing sidewall ...

AIRCRAFT DIESEL ENGINE TURBOCOMPOUND OPTIMIZED
JP Journal of Heat and Mass Transfer, 2015 In order to optimize the design of the thermodynamic cycle of a turbine (Brayton cycle) for using modern common rail as an “active” combustion chamber, it was intended to write the present paper. About the present case, the “active” combustion chamber produces a large amount of the mechanical energy that drives the fan.
