Volatile organic compounds (VOCs) fingerprint of Alzheimer's disease

Respiratory Physiology & Neurobiology, 2015
Alzheimer's disease (AD) is a profoundly life changing condition and once diagnosis occurs, this is typically at a relatively late stage into the disease process. Therefore, a shift to earlier diagnosis, which means several decades before the onset of the typical manifestation of the disease, will be an important step forward for the patient.

QTL validation and stability for volatile organic compounds (VOCs) in apple

Plant Science, 2013
The aroma trait in apple is a key factor for fruit quality strongly affecting the consumer appreciation, and its detection and analysis is often an extremely laborious and time consuming procedure. Molecular markers associated to this trait can to date represent a valuable selection tool to overcome these limitations.

Volatile Organic Compounds (VOCs) for Noninvasive Plant Diagnostics

2013
Plant systems are frequently important agriculture commodity crops, and it can be critical to track emerging pathogen infections or nutrient deficiencies that can limit or prevent food production. While some methods have been developed for in field monitoring, they are frequently invasive and not rapid. Volatile organic compounds (VOCs) are produced by

VOC: Volatile Organic Compounds

2000
Volatile Organic Compounds (VOC) are implicated in different problems of air pollution. Some of these compounds are toxic and dangerous for health. But, they all contribute to ozone formation in the lower troposphere. VOC emissions can come from various sources: road traffic, aircraft transports, combustion plants, solvent use, industry and vegetation.

Volatile organic compounds (VOCs) in urban atmosphere of Hong Kong

Chemosphere, 2002
The assessment of volatile organic compounds (VOCs) has become a major issue of air quality network monitoring in Hong Kong. This study is aimed to identify, quantify and characterize volatile organic compounds (VOCs) in different urban areas in Hong Kong.

Aldehydes, Volatile Organic Compounds (VOCs), and Health

2019
A variety of organic compounds are found in the indoor air. Aldehydes and volatile organic compounds (VOCs) are chemicals categorized with boiling points from 50–100 °C to 240–260 °C; therefore, they can be found indoors in the gaseous phase. Formaldehyde is a dominant aldehyde found indoors.

Ionic liquid technology to recover volatile organic compounds (VOCs)

Journal of Hazardous Materials, 2017
Volatile organic compounds (VOCs) comprise a wide variety of carbon-based materials which are volatile at relatively low temperatures. Most of VOCs pose a hazard to both human health and the environment. For this reason, in the last years, big efforts have been made to develop efficient techniques for the recovery of VOCs produced from industry.

Real time analysis of volatile organic compounds (VOCs) in centenarians

Respiratory Physiology & Neurobiology, 2015
Centenarians are a model to study human longevity and the physiological process of aging. A plethora of studies on this model show the complexity of the system. Laboratory studies fail to find a biomarker of senescence. The real time exhaled breath volatile organic compounds (VOCs) has been suggested as a new biomarker to detect and monitor ...

Volatile Organic Compounds (VOCs) Biofiltration with Two Packing Materials

Environmental Technology, 2006
The treatment of a gas stream containing a mixture of acetone, toluene and trichlorethylene (TCE) was tested in two biofilters packed with compost only (biofilter B1) or a mixture of pozzolan and compost (biofilter B2). The biofilter performance was evaluated at VOCs concentration of 101 mg m(-3) of acetone - 210 mg m(-3) of toluene - 89 mg m(-3) of ...

Colorimetric Polydiacetylene–Aerogel Detector for Volatile Organic Compounds (VOCs)

ACS Applied Materials & Interfaces, 2017
A new hybrid system comprising polydiacetylene (PDA), a chromatic conjugated polymer, embedded within aerogel pores has been constructed. The PDA-aerogel powder underwent dramatic color changes in the presence of volatile organic compounds (VOCs), facilitated through infiltration of the gas molecules into the highly porous aerogel matrix and their ...
