Effects of Different Drying Methods on the Volatile Substances of Dictyophora rubrovolvata Based on HS-SPME-GC-MS and HS-GC-IMS

open access: yesShipin gongye ke-ji
To investigate the impact of different drying methods on the volatile organic compounds (VOCs) of Dictyophora rubrovolvata, HS-SPME-GC-MS and HS-GC-IMS technologies were employed to analyze the aroma changes of the mushroom dried by four methods, which ...

A comparative study of selected sorbents for sampling of aromatic VOCs from indoor air

open access: yes, 2010
Indoor air canbecome pollutedwith VOCs, and understanding the factors which affect adsorption of VOCs from indoor air is important for: (i) the accurate measurement of VOCs, and (ii) to apply mitigation strategies when high analyte concentrations are ...

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

open access: yes, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

Associations of volatile organic compounds/semi-volatile organic compounds exposure on asthma: A review of epidemiological studies and diagnostic applications

open access: yes环境与职业医学
Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) are common organic compounds in indoor and outdoor air, and enter the human body primarily through the respiratory tract and directly damage the respiratory system.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.
