Abstract: Method for preparing a NiO nanosheet structure possessing (111) crystallographic planes as a primary surface with hexagonal holes, comprising the following steps: a) preparing a methanol solution of a nickel salt selected from the group consisting of nickel nitrate, nickel sulphate, nickel chlorate, nickel acetate, and nickel phosphate or a mixture thereof; b) adding benzyl alcohol (BZ), optionally substituted with alkyl, nitro, halo or amino, or a mixture thereof and urea to the solution of (a) in a ratio of Ni to BZ or substituted BZ of at least 1; c) solvent removal and calcination in air of the mixture, plate-like NiO nanosheet precursors therefore, NiO nanosheet structures obtainable by that method as well as various novel uses thereof.

Abstract: The invention relates to the field of macrocyclic host systems and fluorescent dyes. In particular, the invention relates to apparatuses and methods for determining a change in the concentration of an analyte, in particular as a result of a catalysed reaction, preferably an enzymatically catalysed reaction and preferably in an aqueous solution (>50% by weight water).

Abstract: Periclase MgO having a nanosheet structure. The distance of the lattice planes in HRTEM is ?0.24 nm-0.25 nm. Method of preparing periclase MgO having a nanosheet structure including preparation of Mg(OCH3)2 in methanol solution. 4-methoxy benzy alcohol (MBZ) or 4-nitro benzyl alcohol (NBZ) or a mixture thereof is added in a ration of Mg to MBZ and/or NBZ of at least 1. Water/methanol mixture is added to the system. Solvent removal and calcinations in air is performed of the mixture.

Abstract: A method and a corresponding device determines the speed of a moving entity carrying at least two antennas for receiving a transmission signal the antennas being displaced at a predetermined distance. In order to provide a more simple and accurate method which can be used with different transmission signals the method includes the steps of: receiving a transmission signal by the antennas, determining signal characteristics from the transmission signal as received by the determining a time offset between the reception of the transmission signal at the antennas by comparing the signal characteristics determined for the antennas, and determining the speed of the moving entity from the determined time offset, the distance of the antennas and the direction of movement of the moving entity relative to the arrangement of the antennas.
