Although much work has been performed on measure ments and interpretation of light absorption by opaque or nearly opaque solids, it is surprising to note that until recently relatively little reliable experimen

wood was one of the first substances to have the velocity dependence of its resistance to terminal ballistic impact quantified. This was achieved in England and France early in the nineteenth century
Seaweed has different biologically active macromolecules, including polyphenols, fiber, proteins, and polysaccharides. Recent developments in seaweed bioac
H may be stored in either gases or liquids, accordingly, by liquefied and gaseous compressing [7]. Researchers have recently shown a considerable amount of interest in solid-state storage solutions since both existing and newly developed materials are safer, more practical and lighter than ...
The improvement of barrier properties could more especially benefit biopolymers which generally have limited intrinsic barrier properties. Additionally, surface coatings can be used for modulating surface affinity of the packaging towards different liquids and pastes, e.g., to obtain water r...
gases. Respirators generally come in one of two types: a flat-folded form or a shaped form. The flat-folded masks are generally packed flat, but are formed with seams, pleats, and/or folds that enable them to be opened into a cup-shaped configuration that fits a wearer's face. The ...

Nanostructured TiO2 films are deposited on a silicon substrate using 150-W power from the RF magnetron sputtering at working pressures of 3 to 5 Pa, with no substrate bias, and at 3 Pa with a substrate bias of −50 V. X-ray diffraction (XRD) analysis reveals that TiO2 films deposited ...
Polystyrene (PS), a widely used synthetic aromatic polymer, is integral to industries such as packaging, construction, and medical equipment. Its high mole
