Article Abstract
A great deal of effort has been put into developing a novel and cost-effective molecular probe for selective and sensitive recognition of trace amounts of water in organic solvents due to their tremendous advantages in industrial, pharmaceutical, and laboratory-scale chemistry. Herein, a cost-effective chemosensor L has been designed and studied for the detection of trace amounts of water. The addition of water to the DMSO solution of L exhibited an enhancement of fluorescence emission at 460 nm along with a color change from green to colorless. The spectral and color changes occurred due to the self-aggregation of L. The interaction between water and L was performed by dynamic light scattering (DLS), scanning electron microscope (SEM) and finally complemented by quantum mechanical calculation. The detection limit was found to be 0.0093 wt% in DMSO. The L also exhibits a fast visual response and is effectively applied to detect trace amounts of moisture in various food materials (salt, sugar, wheat and honey) and building materials (cement, fly ash, limestone and sand).

The natural tracers δO and δH are essential for tracing hydrological processes by identifying water sources, tracking evaporation loss and floodwater dynamics to enhance water management and flood mitigation strategies. This study employed this approach in the ephemeral, endorheic Cuvelai-Etosha Basin (CEB), spanning northern Namibia and southern Angola, to determine its viability in capturing spatial and temporal hydrological patterns, their timing and interactions during a medium flood condition (2017), and contrasted with a drought year (2014). During the 2017 wet season 219 grab surface water samples were collected from ephemeral waterbodies in four sampling campaigns (February, March, April and May) in addition to a single campaign in May 2014 (63 samples).

Background: Determination of the estradiol hormone in urine is crucial for evaluating congenital adrenal hyperplasia, certain hormone-producing ovarian tumors, polycystic ovary syndrome, liver disease, pregnancy, and infertility. On the other hand, steroid hormones can have destructive effects on the environment, animals, and the endocrine system of humans. Consequently, accurately measuring this hormone's concentration in trace amounts is essential for environmental safety and human health.

Aster incisus is a perennial herbaceous plant belonging to the Asteraceae family, known for its pharmacologically active secondary metabolites. In this study, we conducted a comparative profiling and quantification of secondary metabolites in A. incisus extracts cultivated in two regions, Eumseong (AIE) and Inje (AII), using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and high-performance liquid chromatography with a variable wavelength detector (HPLC/VW).

Carboxylic enantiomers are prevalent in living organisms and synthetic samples that exhibit important biological properties. The profiling of carboxylic enantiomers is beneficial for monitoring physiological states and further unraveling the metabolism mechanisms between carboxylic enantiomers and diseases. In this study, pairs of light and heavy isotope reagents, ()-(3-aminopiperidin-1-yl) phenyl-methanone/-()-(3-aminopiperidin-1-yl) phenyl-methanone (APMA/-APMA), were synthesized and applied to tag the enantiomers of carboxylic metabolites and drugs.
