Abstract: Provided are a current collector for a battery, including: a base material; adhesive layers positioned on the base material; and metal mesh layers positioned on the adhesive layers, in which the metal mesh layer includes a plurality of metal mesh patterns, and holes positioned between the metal mesh patterns, and a method of manufacturing the same. An active material is applied onto the metal mesh layer through the holes of the metal mesh layer, and thus a contact area of the metal mesh layer and the active material is increased, so that it is possible to restrict the active material from being deintercalated from the current collector and improve a cycle lifespan property of a battery.

Abstract: A drone which can be piloted by a user. The drone has at least one or both of a depending head and an outwardly extending elongate handle. A cleaning sheet may be removably disposed on the head, to clean a target surface, such as a floor or countertop. A duster may be removably disposed on the handle, to clean a target surface, such as an elevated surface or clean personal items.

Abstract: Silicone emulsion comprising: at least about 0.025% and less than about 10% of silicone oil; an active amount to emulsify said silicone oil and reduce surface tension of said composition of a surfactant system; and a an effective amount of a buffering system to maintain a pH of said composition to be at least about 6 for a period of at least about 3 months, are useful for controlling wrinkles in fabrics.

Abstract: Disclosed is a method for improving the wear- and corrosion-resistance of a chromium-plated steel substrate by heat-treating the chromium-plated steel substrate under optimum conditions to inhibit a drop in corrosion-resistance of a steel substrate due to fine cracks formed at a chromium layer, and to improve a hardness of the chromium layer. The heat-treating method comprises the steps of: plating the chromium layer onto the steel substrate; and heating the chromium-plated steel substrate in an oxidizing gas environment at above atmospheric pressure to form oxidized layers containing magnetite (Fe3O4) on the surface of the steel substrate, the surface of the steel substrate being partly exposed to the air through penetrating cracks formed in the chromium layer.

Abstract: Disclosed herein are a biaxially textured pure metal or alloy layer deposited by electroplating process on the surface of a single-crystalline or quasi-single-crystalline metal substrate, and a method for manufacturing the biaxially textured pure metal or alloy layer. Specifically, the biaxially textured pure metal or alloy layer is deposited by electroplating process on the surface of a pure metal or alloy substrate having single-crystalline or quasi-single-crystalline orientation. The biaxially textured pure metal or alloy layer has a misorientation on the c-axis of 4° or less and a misorientation on the plane formed by the a-axis and b-axis of 5.2° or less in which the misorientation on the c-axis is determined by a Full Width at Half Maximum of peaks on the &thgr;-rocking curve and the misorientation on the plane formed by the a-axis and b-axis is determined by a Full Width at Half Maximum of peaks on the &PHgr;-scan.
