Summary: The research focused on separating water- and fat-soluble vitamins using micellar systems of HPTLC and PPEC, investigating the influence of mobile phase composition on migration distances and zone separation. Comparisons between HPLC and PPEC showed differences in system capacity, with PPEC performing better for fat-soluble vitamins and exhibiting lower variances and reproducibilities.

Summary: The Sun's magnetic activity influences space weather conditions within the heliosphere. Known variations include the Schwabe Cycle and quasi-biennial oscillations. Detection of periodic signals in Earth's magnetosphere from 1.3 to 1.6 years suggests a connection to solar QBOs transmitted via solar wind.

Summary: This is the 15th Atomic Spectrometry Update focusing on advancements in elemental speciation over a 12-month period from January 2022. The review covers various analytic atomic spectrometry methods for determining oxidation states, organometallic compounds, coordination compounds, biomolecules containing metals and heteroatoms, and the use of metal-tagging for detection. Molecular detection techniques are also included as a complementary approach to speciation analysis. The number of publications and elements covered in the review has decreased, likely due to the impact of the Covid-19 pandemic, but the popular elements studied remain As, Hg, and Se, with a broad range of matrices such as biological, environmental, and food samples.

Summary: Polyvinylidene difluoride membranes are an alternative stationary phase for planar chromatography that offer advantages over traditional techniques, allowing for direct support of analyte development through immunodetection and potential improvement of detection performance. Compatible with a variety of solvents, these membranes facilitate chromatographic separation by redistributing analytes between the membrane and solvent based on their affinities. Separations of crude oils and plant extracts demonstrate the potential of polyvinylidene difluoride membranes to resolve hydrocarbon group types and provide characteristic fingerprints of plant pigments and squalene degradation products.

Summary: The Quasi-biennial oscillation (QBO) describes alterations in tropical stratospheric winds and their impacts, and it is likely to weaken under anthropogenic warming. Simulating and forecasting QBO still face challenges, but improvements in representing the processes governing QBO are expected to enhance predictions of the oscillation and its impacts.

Summary: Veterinary drug residues in food samples of animal origin are currently analyzed using high-performance liquid chromatography combined with sophisticated mass spectrometers. However, the results of this method are only partially consistent with microbiological results and positive findings occur rarely. Therefore, the potential of a non-target planar bioassay screening in veterinary drug residue analysis was studied. The results showed that non-target screening can provide a simple, rapid, eco-friendly, and non-target analysis, filling the gap in routine target analysis.

Summary: The article provides a systematic review of academic engagement literature from 2011 onwards, focusing on knowledge-related interactions between academic scientists and external organizations. It consolidates research on individual, organizational, and institutional antecedents of academic engagement, as well as its consequences for research, commercialization, and society. Findings indicate that academic engagement is influenced by individual characteristics such as scientific productivity, seniority, gender, and commercial experience, as well as social factors like peer effects and disciplinary characteristics.

Summary: Affinity monolith chromatography (AMC) utilizes a monolithic support with a biological ligand to isolate, enrich, or detect target analytes. The specific interactions exhibited by the binding agents make AMC attractive for separating a wide range of compounds. Applications include bioaffinity chromatography, immunoaffinity chromatography, and potential uses in chiral separations and biointeraction studies.
