The Americas: Argentina's De La Rua Flunks Education Reform 101
The recent resignation of Argentina's vice president, Carlos "Chacho" Alvarez, is the latest chapter in that nation's political melodrama. The reform-minded Chief Minister Rodolfo Terragno had already resigned, and President Fernando de la Rua has announced sweeping cabinet changes. At the center of these developments is a major political scandal involving allegations that top presidential aids...
متن کاملHeterojunction double dumb - bell Ag 2 Te – Te – Ag 2 Te nanowires
Growth of isolated axial heterojunction nanowires by a solution phase growth process is reported. The dumb-bell shaped nanowires contain two silver telluride sections at the extremes joined by a tellurium section. Reaction of silver nitrate with tellurium NWs in aqueous solution at a molar ratio of 1 : 1 leads to the formation of amorphous partially silver reacted Te NWs. Low temperature (75 C)...
متن کاملStructural studies on Te-rich Ge-Te melts
The structure of liquid Ge15Te85, Ge25Te75 and Ge33Te67 alloys has been studied by neutronand X-ray diffraction. Datasets obtained by the two techniques have been modelled simultaneously with the reverse Monte Carlo simulation method. As a result, the first coordination numbers and nearest neighbour distances for the studied alloys were estimated. On the base of the experimental data, Ge-Ge bon...
متن کاملTe/C nanocomposites for Li-Te Secondary Batteries
New battery systems having high energy density are actively being researched in order to satisfy the rapidly developing market for longer-lasting mobile electronics and hybrid electric vehicles. Here, we report a new Li-Te secondary battery system with a redox potential of ~1.7 V (vs. Li(+)/Li) adapted on a Li metal anode and an advanced Te/C nanocomposite cathode. Using a simple concept of tra...
متن کاملEffective donor abilities of E-t-Bu and EPh (E = O, S, Se, Te) to a high valent transition metal.
Amido rotation in the chromium(vi), d(0)-system NCr(NPr(i)2)2X is under investigation as a method for the parameterization of ligands for their donor properties toward high valent metals. In this study, two new series were prepared and studied based on chalcogenide ligands, X = EBu(t) and EPh and where E = O, S, Se, Te; the OPh and SPh compounds were previously reported. The ligand donor parame...
