beta-FeOOH particles were prepared by aging aqueous FeCl3 solutions containing Ti(IV), Cr(III), and Cu(II) at room temperature for 360 days. The structures of the formed particles were investigated by various techniques including TEM, XRD, XAFS, and adsorption of N2 and H2O. Ti(IV) markedly impeded the crystallization and particle growth of beta-FeOOH by(More)
An optical modulator with square phase gratings, which are induced by a mosaic structure of electrooptic crystals, is proposed. Analysis and experiments show its utility and the possibility of fabricating it by binding several crystals. An experimental device is built by an array structure using eight 0.9(z) x 0.9(y) x 12.5(x)-mm LiNbO(3) rods. Its 100%(More)
Beta-FeOOH particles were synthesized in the presence of Ti(IV), Al(III), and Cr(III) at metal/Fe atomic ratios of 0-0.1 by the following two methods: hydrolysis of aqueous FeCl3 solutions added to the hydrolysis products of these metal ions (subsequent hydrolysis, SH) and hydrolysis of aqueous FeCl3 solutions dissolving these metal ions (combined(More)
