Analysis of High-speed EMUs Noise Source
, 2015 To improve riding comfort and optimize noise insulation design for high-speed EMUs, the noise source was analyzed, and noise value of high-speed EMUs typical position passenger room was introduced. Noise source under different speed was discussed and indicated mainly from wheel-track noise and pneumatic noise. When the speed of vehicle was under 200 km/

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Advanced Physics Research, EarlyView.This work pioneers a non‐invasive route for strain engineering of quantum states at complex oxide interfaces, making use of supercritical CO2 as a tunable “strain field” to induce room‐temperature ferromagnetism in 3D LaAlO3/SrTiO3 composites. Structural and chemical analyses confirm the magnetism is strictly interfacial and driven by lattice tensile ...
