Phthalate esters, principally di-ethylhexylphthalate (DEHP), are a group of compounds that are commonly employed as plasticizers for polyvinyl chloride in a variety of residential and industrial applications. These phthalate esters have a minimal toxicity in the environment. POLYSORB® ID 37, a combination of diesters derived via esterification of isosorbide with plant-based fatty acids, was created […]

Due to the presence of two types of reactive primary and secondary hydroxyl groups, chitosan (CS), an amino polysaccharide, is a stiff polymer (-OH). It is also a biodegradable, biocompatible, non-toxic, safe, and antibacterial polymer, making it suitable for use in the food and biomedical industries. As a result, biodegradable films based on poly (vinyl […]
Natural compounds found in Tetradium ruticarpum have been reported to be efficient inhibitors of diabetes-related enzymes. This study assessed the inhibitory effects of isolated compounds from T. ruticarpum on protein tyrosine phosphatase 1B (PTP1B) and -glucosidase (3W37), as well as using density functional theory and molecular docking techniques as computational methods to predict ligand stability […]
The goal of this work was to characterise the bleaching of oils by examining the type of adsorptive processes that occur during the bleaching of vegetable oils using clays. According to the existing evidence, acid-leached clays had sites for adsorption of contaminants in oils. The Langmuir and Freundlich isotherms for residual contaminants in cotton and […]
Understanding the coordination chemistry of these amino acids with metals can help us understand the coordination chemistry of proteins in general. Metal ions are required by many proteins in the body, and they are used to activate or deactivate them. The elemental analysis, IR, 1H, 13C NMR, mass and electronic spectroscopy, magnetic and conductance measurements […]
To avoid residual chemicals in seafoods, it is necessary to improve residue monitoring in these foods, which necessitates the development of an accurate and efficient quantitative approach for each target chemical substance. An inexpensive, simple, rapid, and microscale sample preparation technique is described in this chapter, followed by a high-performance liquid chromatography (HPLC) coupled photodiode […]
To improve mechanical system design, parametric Accelerated Life Testing (ALT) is offered as a systematic reliability method for identifying design flaws and correcting them in the creation of a reliable quantitative (RQ) specification. It necessitates: (1) a parametric ALT scheme based on the system BX lifetime, (2) a load inspection, (3) parametric ALTs with corresponding […]
The purpose of this study is to develop a novel method for increasing earthquake protection in structures by forcing them to react to the seismic wave. This is accomplished by having the structure “surf” the earthquake wave as if it were a person riding a wave. A small-scale steel structure building model was created, manufactured, […]
It is proposed that the length of the crack that occurs during brittle fracture of materials be used to calculate the frequency of bit rotation. An adequate cutting angle of the tool is used to create tensile stresses in the soil mass during drilling. The thickness of the soil chips cut off in one revolution, […]
Typical pneumatic soft micro actuators can be created without the use of heavy driving components like pumps and power supplies by using an independent battery-powered mechanism. The fabrication of a thermopneumatically operated soft micro bellows actuator and its experimentally proven standalone operation are presented in this study. Thermopneumatic actuation works by heating a compartment sealed […]
