Heterojunction 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)...

Structural 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...

Te/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...

TE-2015-000265 R1_Final

Continual advances in information and communication technologies (ICT) are revolutionizing virtual education, and bringing new tools on the market that provide virtual solutions to a range of problems. Nevertheless, non-virtual experimentation using Computer-Aided Control System Design tools is still fundamental for future engineers. This paper describes a control course lab element, designed t...
