Abstract:

In this study, the Cu–Te alloy ribbons containing nanocrystalline structures were prepared by melt spinning (MS), and were composed of Cu2−xTe, Cu2Te, Cu3−xTe, and CuTe phases. Crystal grains on both sides of the ribbons were uniformly distributed and the grain size of the contact surface was about 400 nm. The Cu–Te powder was incorporated into the Cu2SnSe3 powder by the ball milling process and the Cu–Te/Cu2SnSe3 thermoelectric composite was prepared by spark plasma sintering (SPS). With the amount of Cu–Te powder increasing, the carrier concentration of the Cu–Te/Cu2SnSe3 composite increased

Abstract:

All the reported structures of Cu<sub>2</sub>Te are found to be metastable with respect to the phase separation Cu<sub>2</sub>Te → Cu<sub>2−x</sub>Te + xCu, which causes a structural transition of Cu<sub>2−x</sub>Te from the monoclinic structure (stable when x = 0) to the trigonal structure (0.125 ≤ x ≤ 0.625). The experimental XRD peaks of Cu<sub>2−x</sub>Te samples should be attributed to the trigonal structure.

Abstract:

Crystalline Cu2Te has recently attracted a great deal of attention owing to its good performance in thermoelectric materials. Yet, knowledge of the amorphous phase is still insufficient, which may restrict its practical application. Here, we have studied the structural and bonding characteristics of amorphous Cu2Te by ab initio molecular dynamics simulations. We show that, compared with its crystal phase, the Cu atoms bond more Cu than Te atoms in amorphous Cu2Te and Te atoms predominantly bond with Cu atoms. In detail, the amorphous Cu2Te is made up of Cu–Te network structures and Cu–Cu high-

Abstract:

Reactions of molten Sn–xCu (x = 0.05 to 1.0) alloys with Te substrate at 250 °C were investigated. A dosage of 0.1 wt% Cu in Sn is found to be effective in suppressing the vigorous Sn/Te reaction by forming a thin CuTe at the solder/Te interface. The CuTe morphology changes from irregular clusters into a layered structure with increasing Cu content in Sn. With the same reaction time, the CuTe thickness increases proportionally to the square root of Cu content in Sn–Cu alloys, suggesting a diffusion-controlled growth for CuTe.

The Fourier transformation of neutron diffraction structure factors was used to generate the pair distribution functions, with the first peak at 1.90 Å due to the overlapping Te–O and Cu–O atomic pairs. Reverse Monte Carlo (RMC) simulations were performed on the structure factors and the six partial atomic pair distributions of Cu–Cu, Cu–Te, Cu–O, Te–Te, Te–O and O–O were calculated. The

The results showed that Te element could improve the wear resistance of copper alloys.

Abstract:

AbstractThe crystal structure of a Te-rich polybasite has been refined by means of X-ray diffraction data collected at room temperature (space group Pm1; R = 0.0505 for 964 observed reflections and 94 parameters; refined formula Ag14.46Cu1.54Sb1.58As0.42S9.67Te1.33). The structure comprises stacking of [(Ag, Cu)6(Sb, As)2(S, Te)7]2–A and [Ag9Cu(S, Te)2(S, Te)2]2+B layer modules in which Sb forms isolated SbS3 pyramids, as occurs typically in sulfosalts, Cu links two S atoms in a linear coordination and Ag occupies sites with coordination ranging from quasi linear to almost tetrahedral.

Abstract:

Doping Sn into the Cu<sub>2</sub>Te lattice can synergistically enhance the power factor and decrease thermal conductivity, leading to remarkably optimized zTs. The lone pair electrons from the 5s orbital of Sn can increase the DOS near the Fermi level of Cu<sub>2</sub>Te to promote PF and reduce κ<sub>e</sub> by decreasing the carrier concentration. This study explores a scalable strategy to optimize the thermoelectric performance for intrinsically highly degenerate semiconductors.

Abstract:

This research employs the COMSOL Multiphysics software (COMSOL 6.2) to conduct rigorous simulations and assess the performance of a thermoelectric module (TEM) meticulously crafted with alumina (Al2O3), copper (Cu), and Bi2Te2.70Se0.30 thermoelectric (TE) materials. The specific focus is on evaluating diverse aspects of the Bi2Te2.70Se0.30 thermoelectric generator (TEG). The TEM design incorporates Bi2Te2.70Se0.30 for TE legs of the p- and n-type positioned among the Cu layers, Cu as the electrical conductor, and Al2O3 serving as an electrical insulator between the top and bottom layers.

Abstract:

In thermoelectric modules, multiple n-type and p-type thermoelectric elements are electrically connected in series on a Cu electrode that is bonded to a ceramic substrate. Defects in the bond between the thermoelectric elements and the Cu electrode could impact the performance of the entire thermoelectric module. This study investigated the effect of plating layers on the bonding strength of p-type Bi–Te thermoelectric elements. Ni and Pd electroplating was applied to Bi–Te thermoelectric elements; further, electroless Ni–P immersion gold (ENIG) plating was applied to Cu electrodes bonded to c

Abstract:

African oil palm (Elaeis guineensis) is grown on 17,000,000 hectares in Southeast Asia, producing oil and the by-product, palm kernel expeller (PKE), for export. Elaeis guineensis is typically produced on weathered acidic soils, with fertilisers and fungicides used to increase production. These amendments can contain elevated concentrations of trace elements (TEs), either as the active ingredient (e.g., Cu-based fungicides) or as contaminants, including F, Zn, As, Cd, Pb and U. TEs may accumulate in soil over time, and be taken up by plants, posing a food-chain transfer risk if allowed to exce

Abstract:

This study assessed environmental metal and metalloids (TE) levels using hair of Apodemus sylvaticus as a non-lethal biomonitor. TE decreased as follows: Zn > Al > Fe > Cu > Pb > Cr > Ni > Mn > Cd > Se > As > Hg; TE widely distributed in soils as Zn, Al, Fe, and Cu, are more abundant than those of ecotoxicological interest, such as Cd, Se, As and Hg. Cd, Pb, Cu, and Cr concentrations are highly variable, while Zn, Fe, and Mn are less variable. TE in hair are below the threshold levels in soil and decrease the same way in both sexes.
