An electric nail filing device includes a cylindrical body having a battery holder attached inside in the body, a cover attached to an open end of the cylindrical body, an on/off switch attached on the cover or the cylindrical body, an electric motor having a metallic rotary filing wheel, and a safety guard cap attached and covering the wheel, shaped like a rectangular prism, a pentagonal prism, a hexagonal prism, or a multiplane prism having multiple planes and a tubular cylindrical housing inner space which has enough space to cover the wheel, in which the safety guard cap has multiple slots on the planes, and an adjustable guard tab attached at closed end of the safety guard cap. Optionally the safety guard cap is covered by a nail debris collector which is shaped like a half-dome covering all other planes of the safety guard cap except one plane.

Electric nail filing device with safety guard cap

A BCC phase hydrogen storage alloy capable of storing approximately 4.0 wt. % hydrogen and delivering reversibly up to 3.0 wt. % hydrogen at temperatures up to 110&#xb0; C. The hydrogen storage alloys also possess excellent kinetics whereby up to 80% of the hydrogen storage capacity of the hydrogen storage alloy may be reached in 30 seconds and 80% of the total hydrogen storage capacity may be desorbed from the hydrogen storage alloy in 90 seconds. The hydrogen storage alloys also have excellent stability which provides for long cycle life.

Hydrogen storage materials having excellent kinetics, capacity, and cycle stability

Disordered multicomponent hydrogen storage material characterized by extraordinarily high storage capacity due to a high density of useable hydrogen storage sites (greater than 10.sup.23 defect sites/cc) and/or an extremely small crystallite size. The hydrogen storage material can be employed for electrochemical, fuel cell and gas phase applications. The material may be selected from either of the modified LaNi.sub.5 or modified TiNi families formulated to have a crystallite size of less than 200 Angstroms and most preferably less than 100 Angstroms.

Hydrogen storage materials having a high density of non-conventional

A disordered multicomponent MgNi based electrochemical hydrogen storage material having a microstructure including a substantial volume fraction characterized by intermediate range order and exhibiting extraordinarily high storage capacity and methods of fabricating same.

Electrochemical hydrogen storage alloys and batteries fabricated from Mg

Non-uniform heterogeneous powder particles for electrochemical uses, and said powder particles comprising at least two separate and distinct hydrogen storage alloys selected from the group consisting of: Ovonic LaNi.sub.5 type alloys, Ovonic TiNi type alloys, and Ovonic MgNi based alloys.
