Poly(p-phenylene-2,6-benzobisoxazole) (PBO) fiber has a high strength, a high modulus, and is light weight, which makes it a leading candidate for soft body armor and fiber reinforced plastic composites. The use of PBO fiber in protective applications is limited by its mechanical …

Historically, petroleum distillates have been used as the carrier for viscosity modifiers in fracturing fluids. There is a growing effort to decrease the environmental impact of fracturing fluids by replacing the petroleum distillates with carriers that are more environmentally friendly. Several factors …

Carbon nanotubes (CNTs) were deposited from a chlorosulfonic superacid solution onto PET substrates by a filtration/transfer method. The sheet resistance and transmission (at 550 nm) of the films were 60 Ω/sq and 90.9% respectively, which corresponds to a DC conductivity of 12,825 …

A novel organic/inorganic nanocomposite is proposed as a luminescent material of a spectral converter (SC) for improving the energy conversion efficiency of solar cells. The nanocomposite consists of a polymer matrix doped with rare earth-centered heterometallic alkoxides, rare earth (RE)-metal (M) nanocluster. …
