Influence of airflow velocity on friction ignition behavior of Ti3Al-based alloy

Cailiao gongcheng
The ignition behavior of Ti3Al-based alloy in 220-380 m/s gas flow environment was studied by using friction ignition method. Combined with numerical calculations, the influence of airflow velocity on surface oxygen concentration and oxidation control ...

Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water

Advanced Materials, EarlyView.
An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...

Airflow Rate Control of Oscillating Water Column for Maximising Wave Energy Capture

e-Prime: Advances in Electrical Engineering, Electronics and Energy
The stalling effect in Oscillating Water Column OWC well turbine−based limits the power generated. This issue is solved by controlling the airflow rate, where the peak waves is predicted and accordingly the airflow speed is reduced. This paper introduces

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

Advanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.

Model tests of fire smoke control effects in highway tunnels

Građevinar, 2020
In this work, a typical tunnel 150 m in length is selected and modelled at a scale of 1:15 to assess its effects on smoke control. A total of 32 model tests on smoke flow pattern and longitudinal temperature distribution have been carried out based on ...
