Abstract: A rhenium (Re) nanostructure is described. The rhenium nanostructure is an elongated nanostructure, such as, nanowire, nanorod, nanotube, branched nanostructure, and hollow nanostructure. The Re nanostructure may be a binary Re-metal nanotube, a binary Re-metal nanowire, and a binary Re-metal nanorod. The binary Re-metal nanostructure is a nanostructure composed of Re and at least one metal or non-metal. The metal may be In, Sn, Sb, Pb, and/or Bi. The nanostructure is in powder or in liquid form.

Abstract: The present invention provides atomic Re nanostructures selected from binary Re-metal nanotubes, binary Re-metal nanowires, binary Re-metal nanorods, Re branched nanostructures, and hollow Re nanostructures.

Abstract: A humidity sensor and a quartz crystal microbalance (QCM) therefor, for measuring low humidity levels, and a method for preparing same. The metallic surface of the QCM is electroplated with a hygroscopic layer. The hygroscopic layer preferably includes Manganese. A salt is formed on the hygroscopic layer. The salt is preferably salt of Manganese, and most preferably Manganese Chloride (MnCl2).

Abstract: A medical implant for producing a therapeutic agent in a body. The medical implant comprises a pair of electrodes and a mechanism for creating an electrical potential between pairs of the electrodes. The electrical potential serves for electrochemically converting at least one substance present in the body, directly or indirectly, into the therapeutic agent.

Abstract: A novel process for the electrodeposition of aluminum on metals, metal alloys and on electrically conducting surfaces. More particularly, the invention relates to the electrodeposition of aluminum on metals such as copper, steel, magnesium, titanium, or uranium; on alloys such as bronze and on substances such as carbon, graphite, etc. The invention relates furthermore to novel solutions which serve as baths for the electrodeposition of aluminum from same. Other and further aspects of the present invention will become apparent hereinafter. According to the invention there is provided:1. An electrolyte for the electrodeposition of aluminum comprising in combination:A. aluminum bromide;B. a solvent selected from the group consisting of toluene, and toluene in admixture with other aromatic liquid solvents of aluminum bromide, other than benzene;C.
