Studies of the flocculation properties of bioflocculant combined with its structure characterization are helpful to develop more effective bioflocculant. This paper reports findings of our research on the flocculation properties of the bioflocculant ZS-7 in the kaolin suspension based on its structure characterization. With the addition of 2 mg/L ZS-7 and 9(More)
From the roots of Adina rubella, four new quinovic acid glycosides, quinovic acid 3-O-beta-D-glucopyranosyl(1-->4)-beta-D-fucopyranoside, quinovic acid 3-O-beta-D-glucopyranosyl(1-->4)-beta-D-fucopyranosyl-(28-->1)-beta-D- glucopyranosyl ester, quinovic acid 3-O-beta-D-glucopyranosyl(1-->4)-alpha-L-rhamnopyranosyl-(28-->1) -beta-D-glucopyranosyl ester and(More)
A bulk nanocrystalline Co–P alloy was subjected to tensile tests. Grain growth from approximately 12 nm in the as-deposited state to about 25 nm after the tensile test was observed. Grain growth was not observed when the deforming volume was increased, or when the specimen was annealed at 433 K or above prior to the tensile tests. 2006 Acta Materialia Inc.(More)
As the semiconductor-process technology advances towards the 90nm-node, more and more waferfabs start to use 193nm EAPSM (Embedded Attenuated Phase-Shift Mask) technology as the main lithography strategy for the most critical-layers. Because the 193nm EAPSM is a relative new technology in the semiconductor industry, it is important for us to understand the(More)
The resonant modes and spatial coherency obtaining in a Fabry-Perot maser interferometer have been studied by Fox and Li,1 and Wolf,2 and others. Fox and Li used an iteration method which describes transmission through an array of perfectly absorbing screens of appropriate aperture to show that after many transmissions a state is reached in which the(More)
