TL;DR: In this paper, silver nanoparticles were impregnated into bacterial cellulose by immersing the cellulose in a silver nitrate solution, which reduced the absorbed silver ion (Ag + ) inside of the bacterial celluloses to the metallic silver particles (Ag 0 ).

TL;DR: Pseudomonas aeruginosa strain SP4, isolated from petroleum-contaminated soil in Thailand, was used to produce a biosurfactant from a nutrient broth with palm oil as the carbon source, and it showed comparable physicochemical properties, in terms of the surface activities.

TL;DR: In this article, the α-chitin whisker-reinforced chitosan nanocomposite films were prepared by solution-casting technique and the length of the as-prepared whiskers ranged between 150 and 800 nm, while the width ranged between 5 and 70 nm.

TL;DR: In this paper, the effect of moisture content on the mechanical properties of composite foams was investigated and it was shown that the flexural strength and flexural modulus of elasticity appeared to be markedly improved with addition of 5-10% by weight of the fibers.

TL;DR: Both biosurfactants could recover oil more effectively than three synthetic surfactants, including polyoxyethylene sorbitan monooleate (Tween 80), sodium dodecyl benzene sulfonate (SDBS), and sodium alkyl polypropylene oxide sulfate (Alfoterra 145-5PO).
