Summary: The study investigates the bio-efficacy of Pimenta dioica leaf derived silver nanoparticles (Pd@AgNPs) against malaria, filarial, and dengue vectors. The synthesized Pd@AgNPs showed larvicidal activity against the larvae of Aedes aegypti, Anopheles stephensi, and Culex quinquefasciatus without affecting non-targeted organisms. The green synthesis of AgNPs offers an effective technique for mosquito control and other therapeutic applications.

Summary: Infrared devices are increasingly used in various applications. This paper introduces a novel dispersive spectrometer that has high-throughput and decoupled spectral resolution. The proposed spectrometer utilizes a two-stage Hadamard transform encoding process to increase the signal-to-noise ratio. With a single-pixel detector, the system can be easily implemented in other desired wavelengths. Additionally, a method is developed to remove the need for uniform illumination and improve the ease of device design for in situ measurement.

Summary: Stable isotope tracers are commonly used with gas chromatography coupled to mass spectrometry for enzyme activity and metabolic pathway studies. In this research, three commercially available instruments were used to analyze samples from a stable isotope labeling study on Rothia mucilaginosa metabolism. The study found that all three GC-MS instruments can be used for stable isotope tracing studies, with high-resolution GC-QTOF MS offering additional capabilities in identifying the chemical structures of unknown compounds.

Summary: This study characterized the volatile aroma of bergamot using headspace solid-phase microextraction coupled with comprehensive two-dimensional chromatography quadrupole time-of-flight mass spectrometry. Gas chromatography-olfactometry was used to characterize the aroma-active compounds. A total of 323 volatile compounds and 29 aroma-active compounds were identified. Comprehensive two-dimensional gas chromatography quadrupole time-of-flight mass spectrometry detected 218 more compounds than gas chromatography-mass spectrometry due to higher peak capacity and separation resolution. The key characteristic volatiles of bergamot included alpha-terpineol, isobornyl formate, alpha-phellandrene dimer, furfural, and o-acetyltoluene. The volatile profiles can be used as a reference for the identification and quality appraisal of bergamot and its products.

Summary: Aroma is crucial in assessing tea quality. Illegal traders often add essence to expired or substandard tea to enhance its aroma for greater profit. Conventional testing methods are time-consuming and costly, while near-infrared spectroscopy and machine vision can only detect powdered solid essences in tea. In this study, proton-transfer reaction mass spectrometry (PTR-MS) and Fourier-transform infrared spectroscopy (FTIR) were used to rapidly detect volatile organic compounds (VOCs) in tea samples adulterated with liquid essence, achieving high prediction accuracies of 0.941 and 0.957, respectively. The study discusses the different application scenarios of the two technologies based on their performance characteristics.

Summary: In this study, a photonic-assisted space-frequency two-dimensional (2D) compressive radar receiver is proposed to achieve high-resolution detection in wide-range scenarios. The system employs spatially adaptive photonic projection basis for compression in the space dimension and photonic compressive sensing for compression in the frequency dimension. The proposed receiver overcomes the resolution deterioration problem of existing photonic compressive receivers and enables wide-range radar detection and inverse synthetic aperture radar (ISAR) imaging with high resolution.

Summary: Modern feed quality sorghum grain has been bred to reduce anti-nutrients, but its inclusion in monogastric animal diets can still result in variable performance. Sorghum grain contains several negative intrinsic factors which may be responsible for muted feed performances. FT-IR and mass spectrometry can be used to discriminate among different sorghum varieties, and could be incorporated into quality control applications.

Summary: This study presents methods for assessing the health quality of products containing betalains, comparing data on phytochemical composition of beetroot cultivars using various techniques. Identified that betalain contributes about 50% to the antioxidant activity in red beetroot. Photometric measurements are recommended for simple analysis of betacyanin and betaxanthin content, while liquid chromatography techniques provide more precise information. The combination of liquid chromatography with high-resolution mass spectrometry is recommended for more detailed metabolomics studies, identifying sixty-four phytochemicals in beetroot samples.

Summary: This study investigated the use of ice glazing containing D-sodium erythorbate (DSE) and vacuum packaging to maintain the quality of large yellow croaker during frozen storage. The results showed that vacuum packaging effectively inhibited ice crystal growth and minimized water loss, while the combination of vacuum packaging and 0.3% DSE-infused ice glazing maintained freshness indicators at low levels throughout the 300-day storage period. This combination was considered the most effective in preserving the quality of the fish.

Summary: This study investigated the transport and hypoglycemic effects of phenolics in mulberry leaves using an in vitro digestion model. The results showed that digested phenolics had higher absorbability and could inhibit glucose digestion and absorption. Phenolics also regulated glucose metabolism. Luteoforol and p-coumaric acid were found to be the primary phenolics strongly correlated with the hypoglycemic ability of mulberry leaves.
