One gram of the carbon, spread over a square meter of aluminum, has the surface area of a football field because it has so many pockets and pits, according to Mark E. McGough, the company's chief executive.
A novel method involving a combination of pulsed YAG laser irradiation and electrochemistry for chemical and physical modification of aluminum surface at a selected area is reviewed.
The detection volume consisted of a synthesized aluminum oxide with large surface area.
Aluminum powder has a specific surface area of 0.713 m2/g, while the specific surface areas of the aluminum foil and casing were 9.26 × 10−3 and 9.26 × 10−4 m2/g, respectively.
By altering the etching time and temperature, the surface area, residual aluminum content, and pore size distribution can be tuned.
Anodized aluminum oxide (AAO) with large surface area through its porous structure and light background color was utilized as the substrate for colorimetric sensors.
Figure 1 Enthalpy as a function of surface area for aluminum oxides and oxyhydroxides.[7].
Attapulgite is a hydrated octahedral-layered magnesium aluminum silicate mineral with large surface area, excellent chemical stability, and strong adsorption.
Formation of larger pore size exposes larger area of aluminum surface and promotes the diffusion of water to the surface of reactive aluminum core, which finally cause reaction rate increase, and vice versa.
ZnO nanowires and anodized aluminum oxide nanoholes were fabricated on alumina and aluminum surfaces, respectively, to increase the surface area and roughness of adhered surfaces.
Anodes of aluminum electrolytic capacitor, which requires large surface area for a high capacitance, are prepared with electrochemical etching.
