Body Surface Potential Mapping Data Conversion Method

Abstract. In body surface potential mapping, data conversion can be required whenever merging data sets taken by slightly different data acquisition systems. In this case, we face with a kind of conversion problem. This paper describes a method for solving the problem according to the least-square principle, so the datasets of physically different body surface potential mapping systems become c...

Formation of stable surface species during alkane conversion

Surface tension mediated conversion of light to work.

As energy demands increase, new, more direct, energy collection and utilization processes must be explored. We present a system that intrinsically combines the absorption of sunlight with the production of useful work in the form of locomotion of objects on liquids. Focused sunlight is locally absorbed by a nanostructured composite, creating a thermal surface tension gradient and, subsequently,...

Trivalent Chromium Conversion Coating for Corrosion Protection of Aluminum Surface

Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...
