Radioassay by gas-liquid chromatography of lipids labeled with carbon-14
A method for radioassay of carbon-I4 labeled substances analyzed by gas-liquid chromatography is described. The column effluent is automatically fractionated by condensing the vapor in a series of cartridges filled with anthracene crystals coated with ...

Comparison of the Coating Structure of Silicon‐Based PECVD Coatings With Varying Organic Content
Silicon‐based PECVD coatings transition abruptly from organic SiOCH to oxidic SiOx at ~32 at% silicon, exhibiting threshold behavior in barrier performance. Chemical composition seems to dominate over porosity: SiOx coatings unexpectedly show higher porosity yet superior barrier properties, possibly due to rigid cage‐like molecular structures ...

Azole antifungal contaminants disrupt mycorrhizal function and risk agricultural sustainability
Global food production is increasingly threatened by soil degradation, climate change and the rising costs of synthetic fertilisers. Circular agriculture, which promotes resource reuse, is a promising solution, but using treated wastewater and biosolids in farming introduces risks from emerging contaminants like pharmaceutical residues.

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass
ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...

Use of a filter-paper disk assay in the measurement of lipid biosynthesis
The precipitation by trichloroacetic acid (TCA) of radioactive lipids on disks of filter-paper, followed by extraction with TCA and water to remove soluble radioactive precursors, provides the means for a convenient assay for lipid biosynthesis.

Exploration of Copper Halide Linear‐Array Detector Prototype for Security Checks
Mn‐doped Cs3Cu2I5 is demonstrated as a highly promising scintillator for X‐ray imaging, featuring high light yield, a low detection limit, and negligible afterglow. A linear‐array detector prototype based on the Mn‐doped Cs3Cu2I5 delivers a spatial resolution of 1.1 lp/mm in food‐safety and security inspections, marking a significant advance in the ...
