Parametric Studies of In-house Resin for Hardness Removal
Abstract: Presence of high amount of calcium and/or magnesium makes the water hard as these ions in water react with other chemical agents and constituents of metallic plumbing etc. The process accelerates in the presence of heat. It decreases the efficiency of the unit operation due to the formation of scales. Hence, scaling is the main issue for which hard water is required to be treated or polished. De-mineralized water finds …

Multifunctional Corn Husk Fibre/PLA–PBAT Hybrid Composites with Carbon-Black Percolation for Structural Self-Sensing Applications
Abstract: This study developed multifunctional polymer composites based on a PLA/PBAT (Polylactic Acid/ Poly(butylene adipate-co-terephthalate)) thermoplastic matrix reinforced with 20 wt.% corn husk fibre (CHF) and functionalized with conductive carbon black (CB) for smart consumer-electronics casings. Alkali treatment modified the lignocellulosic fibre surface, improving fibre–matrix interfacial adhesion and stress transfer within the polymer composite. Thermal characterization showed that the PLA cold-crystallization temperature decreased from 112.5 °C for the unfilled blend to …

Comparison of the Keratinase Gene Sequences of Fast, Slow and Intermediate Feather Degrading Strains of Bacillus licheniformis
Abstract: Feathers are composed of beta keratin which is an insoluble protein resistant to degradation. Bacillus licheniformis has a gene that codes for a keratinase enzyme that hydrolyzes feathers. The DNA sequences of the genes coding for keratinase enzymes of various strains of B. licheniformis were compared. Some strains of the bacteria hydrolyze feathers rapidly, some slowly, and some at an intermediate rate. The mature keratinase enzyme is composed of 274 …
