Surface Chemistry of Mixed-metal Systems
Interest in bimetallic catalysts has risen steadily over the years because of the commercial success of these systems [1]. This success results from an enhanced ability to control the catalytic activity and selectivity by tailoring the catalyst composition [2,3]. A long-standing question regarding such bimetallic systems is the nature of the properties of the mixed metal system which give rise ...
متن کاملModulation of human osteoblasts by metal surface chemistry.
The use of metal implants in dental and orthopedic surgery is continuously expanding and highly successful. While today longevity and load-bearing capacity of the implants fulfill the expectations of the patients, acceleration of osseointegration would be of particular benefit to shorten the period of convalescence. To further clarify the options to accelerate the kinetics of osseointegration, ...
متن کاملMolecular metal catalysts on supports: organometallic chemistry meets surface science.
Recent advances in the synthesis and characterization of small, essentially molecular metal complexes and metal clusters on support surfaces have brought new insights to catalysis and point the way to systematic catalyst design. We summarize recent work unraveling effects of key design variables of site-isolated catalysts: the metal, metal nuclearity, support, and other ligands on the metals, a...
متن کاملStudies of Aluminum Soaps
I t has been shown by McBain and collaborators I that aluminum soaps present characteristics somewhat akin to proteins in their lyophilic colloidal behavior. These soaps, particularly the aluminum disoaps AIOHR~, are solids which can be prepared relatively pure. No macroscopic crystals have yet been obtained but powder x-ray diffraction patterns show structures varying from almost amorphous to ...
متن کاملImpact of surface chemistry.
The applications of molecular surface chemistry in heterogeneous catalyst technology, semiconductor-based technology, medical technology, anticorrosion and lubricant technology, and nanotechnology are highlighted in this perspective. The evolution of surface chemistry at the molecular level is reviewed, and the key roles of surface instrumentation developments for in situ studies of the gas-sol...
