A long-term need has existed in the study of complex redox systems, such as the electron-transferring enzymes found in biological systems, for an accurate method of titrating a system through its various oxidation states using small increments of a reducing agent in solution (1). The methods to be described in this and the accompanying paper (2) were developed concurrently to perform this task....

Aluminum hydride or alane AlH3 is a very important and fascinating material that has recently attracted attention for its potential for different purposes [1, 2]: (i) as an energetic component in rocket propellants, (ii) as a reducing agent in alkali batteries and (iii) as a possible hydrogen source for low temperature fuel cells. For hydrogen storage, this material will be an excellent candida...

The thorium and uranium dihydride dimer complexes [(C5Me5)2An(H)(μ-H)]2 (An = Th, U) have been easily prepared using phenylsilane, which is an efficient and safer alternative to hydrogen gas. The synthetic utility of this new hydriding method has been demonstrated by the preparation of a variety of organometallic complexes, including, for the first time, (C5Me5)2U(SMe)2, (C5Me5)2Th(C4Ph4), (C5M...

frozen at 20 °C, also in the absence of a reducing agent. On the basis of the present data, we give the following recommendations for handling, storage, and shipment: Blood should be kept at 4 °C and must be centrifuged within 6 h. Even in the absence of a reducing agent, plasma can be kept at 4 °C for 3 days without appreciable degradation and shipped if this does not take more than the same t...

The study of novel metal-templated dynamic organocatalytic systems has led to the identification of CuSO4 as the most efficient template to assemble monofunctional prolinamide- and thiourea-modified pyridine ligands. The structural and electronic requirements to assemble an efficient catalyst have been disclosed: both pyridine ligands must bear a 1,3-substitution pattern, and the thiourea ligan...

Extremely long gold nanowires spontaneously assemble in a water-dimethylsulfoxide (DMSO) solution of Au(SCN)4(-). The Au nanowires were crystalline, exhibited a very high aspect ratio, and, importantly, were produced without co-addition of reducing agents. Transparent conductive films were formed by surface deposition of the nanowires and plasma treatment.
