Surfacechemical

Surfacechemical is not a standard field name, but when used it refers to processes and phenomena that occur at interfaces between phases. The term is typically linked to surface chemistry or interfacial chemistry. Surfacechemical studies examine how atoms and molecules interact with surfaces in solid–gas, solid–liquid, or solid–solid configurations. Core topics include adsorption and desorption, surface reactions and catalysis, and changes in surface properties such as energy, work function, and wettability. Because surface behavior can differ markedly from bulk material properties, surfacechemical research relies on specialized techniques and models to resolve atomic-scale interactions at interfaces.

Applications include heterogeneous catalysis, corrosion and passivation, sensor interfaces, coatings and thin films, and energy storage devices where the electrode–electrolyte interface controls performance. Concepts such as chemisorption versus physisorption, surface reconstruction, and defect-mediated reactivity are central to understanding activity and stability. Experimental methods frequently used are X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), infrared spectroscopy (especially ATR-IR), scanning probe microscopy, contact-angle measurements, and surface diffraction. Computational approaches, including density functional theory, help predict adsorption energies and reaction mechanisms at surfaces.

In formal scientific writing, surfacechemical is more often encountered as part of broader phrases rather than as a stand-alone discipline. Lectures and textbooks typically refer to surface chemistry or interfacial science to describe this area of study.
