Relationship Between Volatile Aroma Components and Amino Acid Metabolism in Crabapple (Malus spp.) Flowers, and Development of a Cultivar Classification Model

Horticulturae
The integration of HS-SPME-GC/MS and UPLC-MS/MS techniques enabled the profiling of volatile organic compounds (VOCs) and amino acids (AAs) in 18 crabapple flower cultivars, facilitating the development of a novel VOC–AA model.

Applicability of a SPME method for the Rapid Determination of VOCs

CHIMIA, 2002
A fast method for monitoring volatile organic compounds in water and air is described whereby the VOCs are adsorbed on a SPME and then desorbed directly in a flame ionization detector (FID) or a photoionization detector (PID).

Volatile organic compounds (VOCs) in rivers and estuaries [PDF]

, 2021
Volatile Organic Compounds (VOCs) are a set of low molecular weight compounds typically with a low boiling point. They have previously been observed as important in atmospheric and oceanic environments, however, the relative importance of terrestrial input into oceanic systems has previously not been determined.

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

METHOD FOR RAPID ON-SITE IDENTIFICATION OF VOCs IN EWE MILK

Italian Journal of Food Safety, 2011
Use of a portable GC/MS for on-site identification of volatile organic compounds (VOCs) in ewe milk is for the first time reported. Different VOCs tipically observed in milk were detected with a good repetitivity of the measurement.

Beyond Charge: Field‐Effect Transistors in Multimodal Biosensing Platforms for Biomolecular Interaction Studies

Advanced Electronic Materials, EarlyView.
This review summarizes the developments in field‐effect transistor (FET)‐based dual‐mode sensor platforms and what can be learned from them. It identifies charge as a crucial factor in biomolecular interactions at interfaces, outlines the challenges of hybrid systems, and highlights their benefits.

Counter‐Halide‐Directed Ion‐Pair Passivation Enables High‐Performance Wide‐Bandgap Perovskites for Perovskite/Cu(In,Ga)Se2 Tandem Solar Cells

Advanced Energy Materials, EarlyView.
Counter‐halide engineering of fluorobenzylammonium surface passivators reveals bromide as the optimal partner for wide‐bandgap perovskites. FBz–Br effectively stabilizes halide‐vacancy‐related defects and undercoordinated Pb sites, suppresses non‐radiative recombination, and enhances surface hydrophobicity and thermal stability.
