IMPACT OF SURFACE CHEMISTRY
Selected technological applications of surface company
Heterogenous catalyst technology
Semiconductor based-technology
Medical technology
Anticorrosion technology
Lubricant technology
Surface chemistry at the molecular level
High pressure scanning tunneling microscopy (HP-STM)
Sum-frequency generation (SFG) vibrational spectroscopy
Ambient pressure x-ray photoelectron spectroscopy (AP-XPS)
EXAMPLES
Heterogenous Catalysts Technology
An entitiy that acclerates a chemical reaction without being consumed in the process
Pollution control which reduce the pollutant from autombile by catalytic converter
Semiconductor based-technology
Used to amplify or switch an electronic signal, and an integrated circuit contains millions of transistors etched out of a small semiconductor surface
Compound semiconductors such as GaAs, GaN, and InGan are are optically active materials. Benefits are low noise, high electron mobility and electron velocity
Medical technology
Protein adsorption which produces subsequent platelet adhesion for thrombogenesis on foreign surface
Able to characterize the surface chemistry and structure of complex biointerfaces
Anticorrosion Technology
High reactivity of surfaces may causes undesirable chemical (corrosion) or mechanical water (wear and friction) processes.
The environment of model systems that stimulate real corrosion processes where the corrosive environment may evolve as the corrosion progresses, or where the harsh corrosive environments are hard to reproduce in laboratories
Lubricant Technology
Material confined between two hard surfaces in relative motion. It helps to reduce friction and wear of interferences
Fluid Base Lubricants = Widely used for internal combustion of engines, vehicles, and industrial gear boxes.
