Electrosynthesis of nanofibers and nano-composite films

A method for producing an array of oriented nanofibers that involves forming a solution that includes at least one electroactive species. An electrode substrate is brought into contact with the solution. A current density is applied to the electrode substrate that includes at least a first step of applying a first substantially constant current density for a first time period and a second step of applying a second substantially constant current density for a second time period. The first and second time periods are of sufficient duration to electrically deposit on the electrode substrate an array of oriented nanofibers produced from the electroactive species. Also disclosed are films that include arrays or networks of oriented nanofibers and a method for amperometrically detecting or measuring at least one analyte in a sample.

Wearable compound layer material for machine parts and manufacturing method and equipment thereof

The invention relates to a wearable compound layer material for machine parts and a manufacturing method and equipment thereof. The wearable compound layer material is a metal-based wearable compound layer material which is composed of a matrix metal and lots of particles or fibers dispersed and distributed in the matrix metal, thereby having a multi-phase structure. The wearable compound layer material is manufactured by a direct-current electroplating or pulse electroplating method. The direct-current electroplating or pulse electroplating equipment is composed of parts such as an electroplating power source, an electroplating tank, a metal anode or a metal alloy anode, a machine part substrate cathode, a stirring device, a solution circulating device, a heating and temperature control device, an additive supplementing device and the like. The wearable compound layer material for machine parts provided by the invention is obviously superior in performance to good-quality cast iron wearable parts, good-quality cast steel wearable parts and wearable parts for surface heat treatment of common steel and good-quality steel commonly employed in the present product. The wearable compound layer also has high-temperature abrasive resistance and excellent corrosion resistance while having excellent abrasive performance; and the internal stress of the coating is very low.
