Infrared Techniques Useful in Residue Chemistry [PDF]

open access: bronzeJournal of AOAC INTERNATIONAL, 1965
Abstract Although infrared spectrophotometry is suitable for the measurement and identification of pesticides and their metabolic products because of its inherent characterizing properties, only recently have techniques and instrumentation become adequate for the difficult requirements of residue chemistry.

Microbial keystone taxa drive succession of plant residue chemistry. [PDF]

open access: yesISME J, 2023
Abstract Managing above-ground plant carbon inputs can pave the way toward carbon neutrality and mitigating climate change. Chemical complexity of plant residues largely controls carbon sequestration. There exist conflicting opinions on whether residue chemistry diverges or converges after long-term decomposition.

Chemistry and morphology of dried‐up pollen suspension residues [PDF]

open access: bronzeJournal of Raman Spectroscopy, 2013
Pollen grains are covered with lots of different biochemical compounds, like proteins, saccharides and lipids, which are only loosely attached to the pollen. Therefore, they can be separated from the pollen by suspending them in water. Since these compounds play a key role in many atmospheric processes (e.g.

A green-analytical chemistry method for agrochemical-residue analysis in vegetables [PDF]

open access: greenMicrochemical Journal, 2016
Ten agrochemicals, including fungicides, insecticides, herbicides and a plant growth regulator, were quantified at part per billion levels in complex matrices using a green-analytical chemistry (GAC) method. Liquid chromatography with dual UV/diode array (DAD) and fluorescence (FLD) detections was carried out in a single run, and the second-order DAD ...

Soil and soil-water chemistry below different amounts of logging residues at two harvested forest sites in Sweden [PDF]

open access: goldSilva Fennica, 2015
Logging residues (LR),i.e. tops, branches, and needles, are increasingly being harvested for energy production in Fennoscandia. These residues are temporarily piled on site awaiting transport.

Kinesin-5 Motility is Regulated by the Residue Chemistry of Loop-5 [PDF]

open access: bronzeBiophysical Journal, 2014
Kinesin-5 drives separation of microtubules and organizes the mitotic spindle via its motor domains. More than one component within Kinesin-5 has been implicated in its motile ability; these are Loop-5, the necklinker and the cover neck. In all studies, measured changes in structure, or their implied dynamic motion, were deemed key to the role of these

The Residue Chemistry Transformation Linked to the Fungi Keystone Taxa during Different Residue Tissues Incorporation into Mollisols in Northeast China [PDF]

open access: goldAgriculture
Managing carbon input from crop straw in cropland ecosystems could increase soil organic carbon (SOC) sequestration to achieve C neutrality and mitigate climate change.

Determination of Avermectins Residues in Soybean, Bean, and Maize Using a QuEChERS-Based Method and Ultra-High-Performance Liquid Chromatography Coupled to Tandem Mass Spectrometry

open access: yesSeparations, 2021
Soybean, maize, and bean are crops of great economic importance, but in recent years have suffered with infestations of the caterpillar Helicoverpa armigera, with the main reason being the resistance of this pest to most pesticides.

Development of UHPLC/Q-TOF Analysis Method to Screen Glycerin for Direct Detection of Process Contaminants 3-Monochloropropane-1,2-diol Esters (3-MCPDEs) and Glycidyl Esters (GEs)

open access: yesMolecules, 2021
The U.S. Food and Drug Administration’s (FDA′s) Center for Veterinary Medicine (CVM) has been investigating reports of pets becoming ill after consuming jerky pet treats since 2007. Renal failure accounted for 30% of reported cases.
