Preharvest potassium silicate treatments influence the morphological appearance and enhance nutritional composition of almond kernels

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The almond industry requires new strategies to improve almond kernel quality. The use of biostimulants such as potassium silicate (KSi) is an eco‐friendly and non‐polluting alternative. The aim of this work was to investigate the preharvest application of KSi solutions at 2 and 20 mmol L−1 to ‘Peraleja’ almond trees during two ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

An Efficient Solid Phase Extraction Method for Purification and Analysis of Compound-Specific Plant Sugar Stable Hydrogen Isotope Values. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale The stable hydrogen isotope composition (δ2H) of plant compounds can serve as environmental or metabolic proxies, but interpretations are hindered by insufficient mechanistic understanding. This can be improved by analyzing the δ2H values of metabolic intermediates, such as sucrose, which is the direct substrate of cellulose and a ...

Ethyl formate diluted with nitrogen is an effective biosecurity treatment for brown marmorated stink bug (Halyomorpha halys)

Pest Management Science, EarlyView.
This research found that ethyl formate effectively controls adult brown marmorated stink bugs (Halyomorpha halys) regardless of dormancy state or temperature, at concentrations nine times lower than previous studies. Abstract BACKGROUND The brown marmorated stink bug (Halyomorpha halys) (BSMB) is a biosecurity threat globally. Its most likely avenue of
