Fecal water is a complex mixture of various metabolites with a wide range of physicochemical properties and boiling points. The analytical method developed here provides a qualitative and quantitative gas chromatography/mass spectrometry (GC/MS) analysis, with high sensitivity and efficiency, coupled with derivatization of ethyl chloroformate in aqueous medium. The water/ethanol/pyridine ratio ...

A rapid solid-phase extraction-capillary zone electrophoresis (CZE) method for determining 2,4-dichlorophenoxyacetic acid, 4-(2,4-dichlorophenoxy) butyric acid, and 2,4,5-trichlorophenoxyacetic acid in real water samples is described. Factors affecting the recoveries and detection of the targets are investigated. With samples being acidified to pH 2 and salted by sodium sulfate to 2% (w/w), an ...

Drought is one of the major threats to global food security. Biochar use in agriculture has received much attention and improving it through chemical modification offers a potential approach for enhancing crop productivity. There still limited knowledge on how acidified biochar influences soil properties, consequently its agricultural productivity drought stressed plants. The water efficiency (...

This reply is a supplementary addition to our previous article entitled "Comparison of a Powdered, Acidified Liquid, and Non-Acidified Liquid Human Milk Fortifier on Clinical Outcomes in Premature Infants" as published in Nutrients in July 2016. It provides a response to a comment made by Dr. Fernando Moya to this original article, so the purpose of this is to compare and contrast various persp...

Evidence was found for two previously unreported, nonenzymatic reactions that affected texture retention in acidified red bell peppers. First, oxygen was found to cause rapid softening of the pepper tissue such that it lost at least 40% of the initial tissue firmness within 2 weeks after acidification. Second, sulfite added to the acidified peppers prevented the softening caused by oxygen. Comb...
