Abnormal blood pressure and its association with serum 8-hydroxy-2’-deoxyguanosine among refractory ceramic fiber workers

环境与职业医学
BackgroundPrevious studies have focused on the respiratory system and skin damage caused by refractory ceramic fibers (RCFs). However, investigations into cardiovascular health of workers exposed to RCFs are insufficient. There is limited research on the

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Characteristic volatile organic compounds in exhaled breath of coal workers' pneumoconiosis patients by thermal desorption gas chromatography-mass spectrometry

环境与职业医学
BackgroundCoal workers' pneumoconiosis is a serious occupational disease in China. Exhaled volatile organic compounds (VOCs) can serve as the "breath fingerprint" of internal pathological processes, which provides a theoretical basis for exhaled VOCs to ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
