Printed electronics employing flexible substrate offers prospective features for various applications such as, tactile sensing, energy harvesting, wearable and acoustic wave sensors. In this work, an FPW (flexural plate wave) sensor is printed on thin PZT-PDMS (lead zirconate titanate-poly dimethyl siloxane) composite film with silver ink. The prototype resonator has a resonant frequency of 22....

Field trials carried out upon the second more poisonous compound, bis dimethylamino fluoro phosphine oxide, proved its exceptional effectiveness as an insecticide and since an economic process for its manufacture had been developed and a ready sale of the product was assured, there was ample incentive for its early manufacture. Moreover, the plant erected earlier for the small-scale manufacture...

This study was carried out to characterize the occurrence and concentrations of a variety of volatile organic compounds (VOCs) including aliphatic, aromatic, halogenated, nitrogenous, and carbonyl compounds, in the ambient air of Gumi City, where a large number of electronics industries are found. Two field monitoring campaigns were conducted for a one year period in 2003/2004 and 2010/2011 at ...

a two-week tunnel study was conducted in monterrey, mexico during june 2009 to characterizevolatile organic compound (voc) emissions from the local vehicle fleet and estimate the correspondingemission factors (efs). the loma larga tunnel (llt), a 532 meter-long structure that is mainly used by lightduty gasoline-powered vehicles was used as the experimental set-up. ambient air samples (2-hour a...

Iso propyl alcohol (IPA) is a toxic volatile organic compound (VOC) that is emitted from various paint, pharmaceutical, lithography, and rubber manufacture industries. These emissions may lead to an adverse effect on air quality and thus endanger public health and welfare. The most serious requirements for removing VOCs from waste gases in recent years necessitate the development of innovative ...

In a laboratory experiment, wheat straw (WS), pig slurry (PS) and a mixture of the two materials (WSPS) were added to soil at the rate of 2% on a dry soil basis. Samples of the soil alone and with the amendments were collected at various intervals of time during a one year period and analysed for: pH, electrical conductivity (EC.), NO 3, HPO42-, phenolic compounds and volatile acids. A germinat...

Synthesis of several hydrophobic ionic liquids (ILs), which might be selected as good candidates for degradation of hydrophobic volatile organic compounds in a two-phase partitioning bioreactor (TPPB), were carried out. Several bioassays were also realized, such as toxicity evaluation on activated sludge and zebrafish, cytotoxicity, fluoride release in aqueous phase and biodegradability in orde...

There has been significant interest in the role that carbonaceous aerosols play as radiatively important species in climate and visibility reduction, as potential toxic agents to human health in urban regions, and as surfaces that can catalyze atmospheric chemical reactions. These aerosols are a mixture of primary organic matter that is emitted from a number of sources, including mobile sources...
