Deep Eutectic Solvent-Based Microextraction of Lead(II) Traces from Water and Aqueous Extracts before FAAS Measurements

open access: yesMolecules, 2020
Microextraction procedures for the separation of Pb(II) from water and food samples extracts were developed. A deep eutectic solvent composed of α-benzoin oxime and iron(III) chloride dissolved in phenol was applied as a phase separator support.

Nitrogen isotope analysis of ammonium and glycine [PDF]

open access: yes, 2005
Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (15N)- to- light (14N) isotopic ratios of nitrogen in different biospheric pools.

Gas Chromatography‐Based Methods for Profiling Volatile Off‐Aroma Compounds in Grain Legumes: A Review

open access: yesLegume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine

open access: yesPest Management Science, Volume 82, Issue 6, Page 5850-5860, June 2026.
Ips typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...

An Artificial Antibody‐Based Toolbox Accelerates Validation of Hidden Microproteins Encoded by the Dark Genome

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,
