Shrimp culture industries faced huge economic losses due to white spot disease (WSD) caused by the white spot syndrome virus (WSSV). Microalgae are unicellular and can be found in both freshwater and marine habitats. In recent days, microalgae such as species have been explored for treating WSSV using various protocols including transgenic algae, recombinant protein, and dsRNA.

This study aims to explore the mechanical properties of hybrid glass fiber (GF)/sisal fiber (SF)/chitosan (CTS) composite material for orthopedic long bone plate applications. The GF/SF/CTS hybrid composite possesses a unique sandwich structure and comprises GF/CTS/epoxy as the external layers and SF/CTS/epoxy as the inner layers. The composite plate resembles the human bone structure (spongy internal cancellous matrix and rigid external cortical).

Titanium alloys (TZN) are used in hip and knee replacement for orthopedic implants. Conventional machining, TZN alloys produce higher tool wear rate and poor surface quality, but this can be reduced by Electrical Discharge Machining (EDM) method.
