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 […]

Protein Tyrosine Phosphatase 1B (PTP1B) and ╬▒-Glucosidase (3W37) Inhibitors from Tetradium ruticarpum: In vitro and In silico Study

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, […]

Standalone Thermopneumatic Micro Bellows Actuator using 3D Printing Technology
