BACKGROUND Nanoparticles fabricated from the biodegradable and biocompatible polymer, polylactic-co-glycolic acid (PLGA), are the most intensively investigated polymers for drug delivery systems. The objective of this study was to explore fully the development of a PLGA nanoparticle drug delivery system for alternative preparation of a commercial formulation. In our nanoparticle fabrication, ou...

Lignin, the main natural aromatic polymer was always aroused researchers interest. Currently around 90% of this biomaterial is burned for energy. It has a very complex and complicated structure which depends on the separation method and plant species, what determine difficulties to use as a raw material widely. This research presents a physical method to modify lignin by ultrasonic irradiation ...

Abalone (Haliotis discus hannai) is a widely consumed seafood in Asian countries. Rich protein, abalone for refreshment, pregnancy care, and vitality. Although many studies have found that protein has beneficial effects, the efficiency of extraction method rarely been studied. Therefore, this study aimed to examine effects various factors extraction, including buffer, sonication, salt (NaCl) co...

Among the most reliable techniques for exfoliation of two-dimensional (2D) layered materials, sonication-assisted liquid-phase (LPE) is considered as a cost-effective and straightforward method preparing graphene its 2D inorganic counterparts at reasonable sizes acceptable levels defects. Although there were rapid advances in this field, effect outcome sonication frequency are poorly understood...

We report an innovative, cost-effective, and eco-friendly coating removal technology that removes thick polyurethane-based elastomeric coatings without damaging the underlying metal or glass-polymer composite substrates. The developed eliminates need for chemical- media-based treatments, thus reducing environmental problems such as releasing toxic gases suspended solid particles in air. This wa...
