Surface area determinations of 033 to 038 sq meter per gm of catalyst by physical adsorption and chemisorption methods show that each silver atom of the surface is associated with approximately one oxygen adatom at a monolayer coverage the initial rate of adsorption of oxygen is directly proportional to its pressure.
Ultrasmall silver nanoclusters (agncs) are a novel type of fluorescent nanoprobes that have aroused a great deal of interest in recent years in view of many promising applications in biological research, it is of great importance to explore their behavior in the complex biological environment.
Abstract: the adsorption of adenine on silver and gold surfaces has been investigated combining density functional theory calculations with surface-enhanced raman scattering and angle-resolved x-ray photoelectron spectroscopy measurements, obtaining useful insight.
Sorption of nitrogen, oxygen, and argon on silver-exchanged zeolites, a, x, y, mordenite, bea, l, and zsm-5 at 2882 and 3030 k were studied the nitrogen adsorption capacity, selectivity, and heat of adsorption in the low-pressure region are very high for silver-exchanged zeolites compared to other cation-exchanged samples, showing strong interactions between nitrogen molecules with the silver cations. The silver adsorption normalized to total pore volume as a function of silver equilibrium concentration of solution (the amounts of silver adsorbed on carbons are normalized on a basis of total pore volume from n 2 adsorption at 77 k.
The removal of organosulphur from gasoline by adsorption onto commercial carbon samples loaded with different amounts of silver nitrate was investigated the pore structures of the samples were characterized by nitrogen adsorption studies, while the structure and chemical property of the samples before and after adsorption were examined and analyzed by xrd, ft-ir and sem methods, respectively. Abstract this paper presents the selective adsorption of bromine-metallic complexes of au and ag on composite membranes, as well as the desorption process and redoping of the conducting polymers.
The adsorption of silver diammine complexes on carbon surfaces has been investigated well-characterized carbon supports with known active surface area have been used the silver complex is. Abstract: adsorption of nucleic acid bases on metal surface of nanoparticles has received much attention recently in bio- and nanotechnology, while it still remains a controversial problem in how adenine is adsorbed onto the metal surface as the nitrogen in.
France (received 27 may 1986) abstract—the adsorption of silver diammine complex on graphitized carbon black has been studied in aqueous ammonia solution the carbon black has been gasified to various levels of burnoff in order to increase its active surface area (asa. Abstract adsorption of silver from synthetic photographic and spent ﬁx solutions on granulated activated carbon in a batch process has been investigated the synthetic solutions prepared had similar properties to medical x-ray and photographic process eﬄuents. The adsorption of adenine on silver and gold surfaces has been investigated combining density functional theory calculations with surface-enhanced raman scattering and angle-resolved x-ray photoelectron spectroscopy measurements, obtaining useful insight into the orientation and interaction of the nucleobase with the metal surfaces.
