Volatile Organic Compounds in Uremia [PDF]

PLoS ONE, 2012
Background: Although ‘‘uremic fetor’’ has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia.

Volatile Organic Compounds in Human Breath

Indian Journal of Dental Research, 2022
A comprehensive analysis of volatile organic compounds (VOCs) from the exhaled breath sample is termed as breathomics. Breath samples are a complex mixture composed of a multitude of VOCs and other molecules. The analysis of total VOCs in exhaled breath provides a promising tool for the diagnosis of many diseases because it ...

Exhaled volatile organic compounds for cholangiocarcinoma diagnosis

Liver Research, 2022
The difficulties in the early detection consequent to the lack of sensitive biomarkers render patients with cholangiocarcinoma (CCA) to have poor outcomes. Recently, sensitive and specific volatile organic compounds (VOCs) were identified in several cancers. However, the VOC profiles in CCA are not well-studied.

Characteristics of VOCs Emissions from Circulating Water of Typical Petrochemical Enterprises and Their Impact on Surroundings

Atmosphere, 2022
The petrochemical industry is regarded as the main source of anthropogenic VOCs emissions in China. As one of the main sources of unorganized emissions, circulating water is scarcely studied and reported.

The nature of K-induced 2H and 1T’-MoS2 species and their phase transition behavior for the synthesis of methanethiol (CH3SH)

iScience, 2022
Summary: The one-step reaction approach from syngas with hydrogen sulfide (CO/H2/H2S) over potassium (K) promoted Molybdenum disulfide (MoS2) materials can provide alternatives for the synthesis of methanethiol (CH3SH).

Cu2In alloy-embedded ZrO2 catalysts for efficient CO2 hydrogenation to methanol: promotion of plasma modification

Frontiers in Chemistry, 2023
Cu1In2Zr4-O-C catalysts with Cu2In alloy structure were prepared by using the sol–gel method. Cu1In2Zr4-O-PC and Cu1In2Zr4-O-CP catalysts were obtained from plasma-modified Cu1In2Zr4-O-C before and after calcination, respectively. Under the conditions of
