Abstract:
The present invention provides a novel UV-resistant material, which is a host-guest nano-composite made with micro- and mesoporous molecular sieves of types X, Y, A, STI, ASM-5, MCM-41 and the series thereof, and SBA and the series thereof being the host and the nano-cluster Ti02, ZnO, Ce02, and Fe203 being the guest. The composite represents strong absorption in the UVA-UVB ranges, which can be used as the UV resistant agent in cosmetics, coatings, rubber and plastic industry.
Abstract:
A nonmagnetic powder, used for the nonmagnetic layer of a coated type magnetic recording medium having a multilayer structure, has good dispersibility in the binder in which it is dispersed to prepare a coating material that is applied to the nonmagnetic layer. The nonmagnetic powder has an iron compound as its principal component and exhibits a maximum pore volume value in a pore diameter range of 0.01 μm to 0.05 μm within a pore diameter range of 0.0018 μm to 0.1 μm in which the relationship between pore diameter and pore volume is calculated by a mercury injection method. The nonmagnetic powder exhibits a cumulative pore volume value in a pore diameter range of 0.0018 μm to 0.01 μm that is not more than 30% of the cumulative pore volume value in the pore diameter range of 0.0018 μm to 0.1 μm.
Abstract:
The present invention is directed to the selective removal of ferric ion and/or ferric compounds from valuable metal recovery process streams.
Abstract:
This invention provides magnetic nanoparticles, which when placed in a magnetic field are selectively heated at a certain frequency of the magnetic field, as a function of their size, composition, or both. The invention also provides for use of such nanoparticles, in applications including, inter alia, selective nanoparticle heating and applications thereof, hyperthermia induction in cells or tissue, remote alteration of protein structure and/or drug delivery.
Abstract:
Iron particles for purifying soil or ground water of the present invention comprise a mixed phase of α-Fe phase and Fe3O4 phase, and having a BET specific surface area of 5 to 60 m2/g, an Fe content of not less than 75% by weight based on the weight of the iron particles and a sulfur content of not less than 1,000 ppm. The iron particles are capable of decomposing or insolubilizing harmful substances such as organohalogen compounds and/or heavy metals, cyanogen, etc. contained in the soil or ground water in efficient, continuous and economical manners.
