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: This study investigated the binding strength of Naringenin (NAG) to Alpha-Chymotrypsin (a-Chy) using multispectral methods and computational simulation techniques. The results showed that NAG reduced the intrinsic fluorescence of a-Chy through static quenching and induced a more flexible conformation. Thermal stability data and kinetic analysis supported these findings.

Summary: A method for quantitatively characterizing the thickness of PTFE/alpha-alumina composites transfer films was proposed based on chemical and morphological analysis, showing a linear correlation between the peak area of the CF2 antisymmetric stretching vibrational absorption peak and transfer film thickness. This provides a simple, rapid, and nondestructive approach for measuring polymeric transfer film thickness.

Summary: This study combined laser direct in-frared (LDIR) and Fourier-transform infrared (FTIR) methods to investigate microplastics in agricultural soils. The results showed that microplastics were present in high abundance, with particles ranging from 10 to 500μm accounting for the majority. Polyethylene, polypropylene, and polyvinyl chloride were the dominant polymer types. Reclaimed water from sewage treatment plants, drip irrigation utilities, and residual plastic film were identified as potential sources. The study also highlighted the underestimation of microplastic contamination in agricultural soils using visual counting methods.

Summary: The study introduces a high-speed FTIR spectroscopy technique called phase-controlled Fourier-transform infrared spectroscopy (PC-FTIR) capable of measuring MIR absorption spectra at a rate of above 10 kHz. It demonstrates a high scan rate with a high signal-to-noise ratio for various spectral bandwidths by arbitrarily adjusting the instrumental spectral resolution. This high-speed MIR spectrometer could be particularly useful for measuring non-repetitive fast phenomena and acquiring a large amount of spectral data within a short time.

Summary: Partial evaporation and solidification of plastic materials, mainly microplastics, onto coastal rocks can form a new solid structure called plastitar. These formations have been found in several islands of the Canary Islands archipelago and can permanently attach to the rock, occupying a significant portion of the sampled area. The plastitar primarily consists of tar and polyethylene, with microplastics in the form of fragments, pellets, and lines. The increasing presence of plastics, particularly microplastics, in coastal environments may lead to the common occurrence of these new plastic formations, which require further investigation on their long-term effects on coastlines.

Summary: Soil salinity has a significant impact on agricultural production, especially in low-lying coastal areas where saltwater intrusion is a growing concern. Monitoring salinity is challenging due to the influence of soil moisture on the soil's spectral signature. The study found that Fourier-transform infrared spectroscopy can be used to map salt-affected soils, particularly in inaccessible areas. Advancements in thermal satellite sensors may provide possibilities for monitoring soil salinity in the future.

Summary: The study revealed that chitosan hydrochloride coating loaded with vanillic acid or caffeic acid can effectively control anthracnose decay in avocados, reduce decay occurrence to a lesser extent, and provide some protection for fruit quality. This coating may achieve these effects by inducing the expression of specific genes, increasing skin epicatechin content, and reducing LOX expression in the fruit. Additionally, the complex of chitosan and phytochemicals may help prevent fungal invasion and reduce fruit damage.

Summary: This study confirmed the possibility of using FTIR spectra and multivariate analyses to accurately assign milk samples to their breeds of origin. R-VAL(2) values obtained with the CRV procedure were moderate to high for the majority of coagulation traits, with RMSEVAL and ratio performance deviation values increasing as the coagulation process progresses from rennet addition. Prediction accuracy obtained with the SCV were strongly influenced by the breed, presenting general low values restricting a practical application.

Summary: Resistance to antimalarial medicine poses a threat to malaria eradication efforts worldwide. Recent reports from the World Health Organization have identified partial resistance to artemisinin in Southeast Asia and Africa, highlighting the need for new antimalarial drugs. Traditional medicine in Indonesia has identified several plant species with potential antimalarial properties, including Andrographis paniculata, Alstonia scholaris, Carica papaya, and Physalis minima. Among these, A. paniculata shows the highest potential as an antimalarial, with its extract and andrographolide exhibiting strong activity in vitro and in vivo. A. scholaris and C. papaya also show promise and warrant further investigation, while P. minima remains relatively understudied but presents an opportunity for exploration.
