A study on the reactivity and physicochemical properties of coatings based on acrylated black seed oil coatings through crosslinking at ambient temperature
Environmentally friendly organic coatings which are water-based, have low or no solvents and good physical properties based on the use of acrylate monomers/acrylate oligomers originating from vegetable oils are gaining attention as we move towards sustainable chemistry. Using thermal methods with acrylate and methacrylate monomers in the presence of initiators produces transparent films.

Interactive effects of temperature and cu on distinct life stages of common tropical copepod across gener
The tropical water environment faces increasing exposure to temperature extremes and contaminants stemming from human activities. Elevated temperatures and pollution levels in rivers and ponds have the potential to induce cumulative impacts on the diversity of aquatic ecosystems. However, the combined effects of these environmental changes on the life cycle of the Eucyclops euacanthus copepod, a bioindicator of aquatic ecosystem remain understudied.

Phase tailoring of dense tantalum films for improving hardness of titanium implants using negative substrate bias during DC sputtering at low temperature
This work reports the deposition of a dense α-Ta and β-Ta films to enhance the surface hardness and biocompatibility of Ti by applying a different negative substrate bias during direct current (DC) sputtering. When a Ta film was deposited with a negative substrate bias voltage of 70 V, the microstructure of the film exhibited a single β-Ta phase.

Isolation of cellulase enzyme from water used in white pepper processing
Cellulase, an enzyme that helps soften fruit peel, is produced by plants during the fruit ripening phase. Utilizing the immersing water from the white pepper processing to extract cellulase will help minimizing environmental waste and retrieving valuable compounds. Some factors affecting the cellulase yield from the immersing water of pepper were studied, including the degree of ripeness of peppercorn, immersing temperature and time.

Adaptive proportional-integral control design for a class of continuous stirred tank reactors with uncertain parameters
Mathematical model of reaction systems contains experimental parameters such as reaction enthalpies, which may be inaccurate and, therefore, severely affect the computation as well as the implementation of feedback control laws. This paper aims to design an adaptive PI-like controller to regulate a chemical reaction system by means of the Lyapunov theory.

Evaluating and predicting the impact of land use and land cover change on land surface temperature in Lac Duong district, Lam Dong province, Vietnam
Land use and land cover (LULC) change is a key factor influencing land surface temperature (LST) dynamics. This change reflects partly global warming and climate change at local and regional scales. This study aimed to evaluate the effect of LULC on LST change in Lac Duong mountainous district, Lam Dong province in the past 10 years (2013 - 2023), and predict the LST change in 2030.
