The volatile component of olive oil is a complex mixture of chemicals that determines the oil’s aroma (Bianco et al., 2006) and influences quality and consumer acceptability. The relationship between number and quantity of volatiles and the aroma (Garcia-Gonzalez et al., 2007) is not simple...
rapid electron/ion transfer, moderate adsorption capacity, excellent catalytic activity and abundant active sites to promote the redox of LiPSs/Li2S [15]. The catalytic capacity of sulfur catalysts is firstly related to their conductivity. The LSBs involve multi-electron reaction, and the high...
For instances, investigating the Fe-nitride thin films [2–7] uncovered that the crystal structures, saturation magnetization (MS) and Curie temperature (TC) of the FeN films could be modulated by adjusting the concentration of N2 in the mixture of Ar and N2 sputtering gases. The MS value ...

Then, the mixture was 15 min centrifuged at a speed of 4500 r/min. The pellets were three-time washed with dehydrated ethanol. After redissolving of collected precipitate (termed crude CPs), dialysis and the lyophilization were subsequently conducted at -50°C under vacuum. Finally, the ...
However, we need to better understand how material type and sample location influence microbial growth and mVOCs in different building materials under different relative humidity conditions to ultimately elucidate the impact on the chemistry within a damp home. The goal of this study is to understand...
Libraries were pooled in equimolar quantities and paired-end sequenced on an Illumina HiSeq 2500 platform using a Rapid Run Mode flowcell and the V3 sequencing chemistry following Illumina's recommended protocol to generate paired-end reads of 100 bases in length. RNA-seq bioinfomatics pre-...
days of age. It has also been found that prenatal treatment of rats with eitherAroclor 1254, which contains coplanar PCBs with AhR agonist activity, or a reconstituted mixture of PCB congeners that simulates the congener mixture found in human milk caused decreased testosterone levels during ...
There are many papers which are dealing with the emission of volatile compounds from plants under abiotic and biotic stresses. Our review is focused on the emission of volatile organic compounds from plants under climate change and their implication in atmospheric chemistry and human health....
