Resumen
The present study surveys potential antibacterial synergism effects of silver nitrate with eight other metal or metalloid-based antimicrobials (MBAs), including silver nitrate, copper (II) sulfate, gallium (III) nitrate, nickel sulfate, hydrogen tetrachloroaurate (III) trihydrate (gold), aluminum sulfate, sodium selenite, potassium tellurite, and zinc sulfate. Bacteriostatic and bactericidal susceptibility testing explored antibacterial synergism potency of 5760 combinations of MBAs against three bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus) in three different media. Silver nitrate in combination with potassium tellurite, zinc sulfate, and tetrachloroaurate trihydrate had remarkable bactericidal and bacteriostatic synergism effects. Synergism properties of MBAs decreased effective antibacterial concentrations remarkably and bacterial cell count decreased by 8.72 log10 colony-forming units (CFU)/mL in E. coli, 9.8 log10 CFU/mL in S. aureus, and 12.3 log10 CFU/mL in P. aeruginosa, compared to each MBA alone. Furthermore, most of the MBA combinations inhibited the recovery of bacteria; for instance, the combination of silver nitrate–tetrachloroaurate against P. aeruginosa inhibited the recovery of bacteria, while three-fold higher concentration of silver nitrate and two-fold higher concentration of tetrachloroaurate were required for inhibition of recovery when used individually. Overall, higher synergism was typically obtained in simulated wound fluid (SWF) rather than laboratory media. Unexpectedly, the combination of A silver nitrate–potassium tellurite had antagonistic bacteriostatic effects in Luria broth (LB) media for all three strains, while the combination of silver nitrate–potassium tellurite had the highest bacteriostatic and bactericidal synergism in SWF. Here, we identify the most effective antibacterial MBAs formulated against each of the Gram-positive and Gram-negative pathogen indicator strains.

Resumen
In this work nickel octadecylphthalocyanine (NiPc(C10H21)8) and cadmium telluride quantum dots (QDs) capped with thioglycolic acid (TGA) are adsorbed on single walled carbon nanotubes (SWCNT) to form NiPc(C10H21)8 -SWCNT-QDs conjugate. X-ray photoelectron, ultra violet/visible and Raman spectroscopies are used to characterize the conjugate. SWCNT, poly- Ni(O)Pc(C10H21)8 , NiPc(C10H21)8 -SWCNT and NiPc(C10H21)8 -SWCNT-QDs complexes are used to modify glassy carbon electrode (GCE) and used for the electro-oxidation of pentachlorophenol as a test molecule. NiPc(C10H21)8 -SWCNT-QDs electrode gave the best detection current for pentachlorophenol.

Resumen
Reactively sputtered nickel oxide (NiOx) films provide transparent, antireflective, electrically conductive, chemically stable coatings that also are highly active electrocatalysts for the oxidation of water to O2(g). These NiOx coatings provide protective layers on a variety of technologically important semiconducting photoanodes, including textured crystalline Si passivated by amorphous silicon, crystalline n-type cadmium telluride, and hydrogenated amorphous silicon. Under anodic operation in 1.0 M aqueous potassium hydroxide (pH 14) in the presence of simulated sunlight, the NiOx films stabilized all of these self-passivating, high-efficiency semiconducting photoelectrodes for >100 h of sustained, quantitative solar-driven oxidation of water to O2(g).

Resumen
Cadmium Zinc Telluride (CdZnTe) is a ternary Ⅱ- Ⅵundeviating band gap semiconductor with cubic Zinc blende formation and it is a propitious material for ambient temperature xray as well as gamma ray sensor detectors. Cadmium Zinc Telluride (CdZnTe) thin layer coating were developed on nickel substrate by chemical bath deposition in non-aqueous approach. The as grown films were inspected by X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM), Scanning electron microscope, Fourier transform infrared spectroscopy (FTIR), PL spectra, UV spectra, Raman spectroscopy and FourProbe analysis. Studies tell that as grown films are poly-crystalline in nature along with cubic zinc blende formation. The structural properties like crystallite size, lattice constant, micro strain as well as dislocation density were evaluated. FESEM and SEM analysis reveals that the as developed films are smooth and equal sized uniform spherical grains distributed in single state as well as in cluster form. The average size of grain film is observed to be 12.33 nm. Optical study reveals the broad transmittance escorted by the band gap energy of 2.2eV. Electrical study reveals that resistivity of as grown film is 5.1×105 Ω-cm at room temperature.

Resumen
The crystal structure of the title compound, nickel telluride, with composition Ni2.60Te2, has been the subject of a previous investigation based on X-ray powder data, when a slightly different composition of Ni2.58Te2 was determined [Gulay & Olekseyuk (2004). J. Alloys Compd, 376, 131–138]. In contrast to the previous refinement in the space group Pmc21, the redetermination from single-crystal data reveals a centre of symmetry and the structure was refined in the space group Pnma with improved precision for the atomic coordinates and interatomic distances. The structure can be described as a c × a × (3a)1/2 distorted orthorhombic variant of the hexagonal Ni1.10Se0.16Te0.74 structure. All atoms are situated on mirror planes.

Resumen
Solar cell is one of the promising alternative green energy sources that can provide free electricity when sunlight is converted. The absorbent materials and their synthesis methods are subject of interest mainly due to solar panel installation cost despite of free electricity generated. The well-known silicon solar cells made, either amorphous or polycrystalline are good in conversion efficiency up to 17%, but their high cost make the researchers to look for alternate materials. Semiconducting materials in thin film form such as InP, SnO2 and ZnO are being studied as the alternative materials, but are not commercialised due to their poor conversion efficiency. Another group of semiconductor compounds known as transition metal chalcogenides (TMC) have been developed to be used as the absorbent materials. Consisting of transition metals and chalcogenides (S, Se and Te), they show promising solar absorbent properties such as semiconducting band gap, well adhesion to substrate and good conversion with better cost-effective. There are many TMC compounds synthesised, including copper indium selenide (CIS), ZnTe2, CdSe etc. Nickel, one of the transition metals synthesised with chalcogenides are referred as nickel chalcogenides. There are many possible combinations of nickel chalcogenides such as NiS2, NiSe, NiSe2 and Ni3Se2. The combination of nickel and telluride are the fewest being observed due to the nature of tellurium that is poorly-adhesive onto the substrate. Therefore, NiTe2 thin film is being electro-synthesised onto the indium tin oxide (ITO) coated glass substrates and their properties are studied. The additives are being used to improve the adhesion between the film and substrate. Cyclic voltammetry experiments have been done prior to electrodeposition in order to get the electrodeposition potential range where the observable reduction range is between-0.9-(-1.1) V. The electrodeposition is carried out using the potentials in the reduction region, producing the well-adherent, well-distributed and dark-coloured thin films.

Resumen
A theoretical investigation on structural, dynamical, phase diagram and thermodynamic properties of beryllium telluride (BeTe) under high pressure and temperature is presented in the framework of density functional theory. The calculated structural parameters of BeTe in both zinc blende (ZB) and nickel arsenide (NiAs) structures are in reasonable agreement with available experimental data and previous theoretical work. The phonon dispersion relations, dielectric tensor and Born effective charge are investigated within the density functional perturbation theory (DFPT). The investigation of the phase diagram indicated that the NiAs structure BeTe becomes stable at high pressure and temperature. Based on the quasiharmonic Debye model, the pressure and temperature dependences of bulk modulus, Grüneisen parameter, Debye temperature, specific heat and thermal expansion coefficient are all successfully obtained. We hope that the theoretical results reported here can give more insight into the structural and thermodynamic properties of other semiconductors at high temperature and pressure.

Resumen
The present paper describes the contacting technology to the diluted magnetic semiconductor Cd1-xMnxTe having potential applications in optoelectronic and spintronic devices. For efficient spin injection into a spintronic material, a matching ohmic contact is the demand of the time. Since cadmium telluride has a well-known contact problem, its manganese-doped counterpart is also facing a similar difficulty. In the present case Cd1-xMnxTe was fabricated using thermally assisted interdiffusion and compound formation between repeated stacked elemental layers of manganese, cadmium and tellurium. A wet electroless deposition technique was employed to deposit manganese doped nickel phosphide as a magnetic contact onto Cd1-xMnxTe. It appeared that the contact resistivity improved compared to the case of gold contact. The details of the contacting technology and the results have been described in the text of the paper.

Resumen
We have studied structural, mechanical and dynamical properties of PdC and CdC compounds to predict the most stable structure. We have focused on seven binary structure types as rock salt (RS), caesium chloride ( CsCl ), zinc blende (ZB), wurtzite (WZ), tungsten carbide (WC), cadmium telluride ( CdTe ) and nickel arsenide ( NiAs ). For modelling exchange-correlation effects we have used generalized gradient (GGA) approximation based on Perdew–Burke–Ernzhorf functional (PBE). The polycrystalline elastic moduli such as Young's and shear moduli, Poisson's ratio, sound velocities, Debye temperatures and shear anisotropic factors have been presented for mechanically stable structures using second-order elastic constants calculated from the stress-strain relations. The results show that PdC is thermodynamically, mechanically and dynamically stable in ZB structure. On the other hand, while CdC is energetically in favor of RS structure, it is mechanically and dynamically stable in ZB structure.

Resumen
Due to inherent phase separation, it has been so far impossible to grow ideally stoichiometric (1:1) tetragonal (P 4/n m m) iron telluride. The excess iron ions are located in the inter-planar positions and usually represented as a fraction x in a general formula Fe1+xTe [1], where x ranges from about 4% to 17%. The additional iron has been found to negatively correlate with the level of anion site doping and subsequently with hindering the superconductivity (SC), for example in the Fe(Te,Se,S) [2] series, where SC can be induced by doping with selenium or small amounts of sulfur. A binary Fe1+xTe orders magnetically into incommensurate magnetic structure with the transition temperature and crystal structure in the magnetic state depending on the excess iron. For x<0.12 a monoclinic (P 21/m) distortion was observed and for x>0.12 an orthorhombic one (P m m n). In our work, we attempted to create and investigate compounds electronically equivalent to variable iron stoichometry by substituting Fe with chromium (3d electron deficient) or nickel (3d electron rich). Single crystal samples several millimeter in size were grown by solidification from melt method in the substitution range 0.025 to 0.1 and only in the case of nickel the incorporation of dopant into host lattice was confirmed. Despite low effective Cr content in the single crystal form [3], neutron powder diffraction (NPD) of polycrystaline specimens revealed systematic decrease of long range magnetic moment and gradual suppression of monoclinic (M) distortion in both series. In the Cr doped series, the structure evolved through a mixed phase region into orthorhombic (O) one (Fig. 1), whereas in the nickel system a complete restoration of tetragonal symmetry was found. The suppression of magnetic ordering and lack of the structural distortion did not result in the SC. This work is supported by the Polish National Science Centre grant No 2011/01/B/ST3/00425

Resumen
La3Te4-based rare-earth telluride is a kind of n-type high-temperature thermoelectric (TE) material with an operational temperature of up to 1273 K, which is a promising candidate for thermoelectric generators. In this work, the Sm substitution in La3−xSmxTe4/Ni composites is reported. The electrical transport property of La3−xSmxTe4 is modified by reducing carrier concentration due to the substitution of Sm2+ for La3+. The electric thermal conductivity decreases by 90% due to carrier concentration reduction, which mainly contributes to a reduction in total thermal conductivity. Lattice thermal conductivity also decreases by point-defect scattering by Sm doping. Meanwhile, based on our previous study, compositing nickel improves the thermal stability of the La3 − xSmxTe4 matrix. Finally, combined with carrier concentration optimization and the decreased thermal conductivity, a maximum zT of 1.1 at 1273 K and an average zTave value of 0.8 over 600 K–1273 K were achieved in La2.315Sm0.685Te4/10 vol.% Ni composite, which is among the highest TE performance reported in La3Te4 compounds.

Resumen
In this paper, we successfully fabricate compact and uniform cadmium telluride (CdTe) films on flexible nickel foils using simple electrodeposition technique and sintering in a nitrogen atmosphere. The effect of the concentration of sodium tartrate on the structures and properties of the deposited CdTe thin films are studied. Various test techniques are used to characterize the results. The results of XRD analysis show that the highest crystallinity film is obtained when the added sodium tartrate concentration is 0.05 M. With the increase of sodium tartrate concentration, the composition of the film gradually changes from Te-rich to Cd-rich, and the thickness of the film becomes thin gradually. We also find that the CdTe thin film prepared under 0.05 M sodium tartrate shows the best optical and optoelectronic properties. Thus, a moderate amount of sodium tartrate is added into an acidic solution as surfactant for CdTe thin film fabrication. Moreover, sodium tartrate is easily volatilized from the film during the annealing process because of its small molecular weight, which can prevent the carbon precipitation.

Resumen
Mineralization of Te and Se was found in gold deposits and uranium occurrences, located in the Paleoproterozoic greenstone belts in Northern Fennoscandia. These deposits are of different genesis, but all of them formed at the late stages of the Svecofennian orogeny, and they have common geochemical association of metals Au, Cu, Co, U, Bi, Te, and Se. The prevalent Te minerals are Ni and Fe tellurides melonite and frohbergite, and Pb telluride altaite. Bismuth tellurides were detected in many deposits in the region, but usually not more than in two–three grains. The main selenide in the studied deposits is clausthalite. The most diversified selenium mineralization (clausthalite, klockmannite, kawazulite, skippenite, poubaite) was discovered in the deposits, located in the Russian part of the Salla-Kuolajarvi belt. Consecutive change of sulfides by tellurides, then by selenotellurides and later by selenides, indicates increase of selenium fugacity, fSe2, in relation to fTe2 and to fS2in the mineralizing fluids. Gold-, selenium-, and tellutium-rich fluids are potentially linked with the post-Svecofennian thermal event and intrusion of post-orogenic granites (1.79–1.75 Ga) in the Salla-Kuolajarvi and Perapohja belts. Study of fluid inclusions in quartz from the deposits in the Salla-Kuolajarvi belt showed that the fluids were high-temperature (240–300 °C) with high salinity (up to 26% NaCl-eq.). Composition of all studied selenotellurides, kawazulite-skippenite, and poubaite varies significantly in Se/Te ratio and in Pb content. Skippenite and kawazulite show the full range of Se-Te isomorphism. Ni-Co and Co-Fe substitution plays an important role in melonite and mattagamite: high cobalt was detected in nickel telluride in the Juomasuo and Konttiaho, and mattagamites from Ozernoe and Juomasuo contain significant Fe. In the Ozernoe uranium occurrence, the main mineral-concentrator of selenium is molybdenite, which contains up to 16 wt.% of Se in the marginal parts of the grains. The molybdenite is rich in Re (up to 1.2 wt.%), and the impurity of Re is irregularly distributed in molybdenite flakes and spherulites.

Resumen
ABSTRACTThe cadmium telluride (CdTe) photovoltaic (PV) comprise an efficient and cost-effective technology for harvesting solar energy. However, device efficiency remains limited in part by low-open circuit voltage (VOC) and fill factor (FF) due to inefficient transport of photo-generated charge carriers. Given the deep valence band of CdTe, the use of copper/gold (Cu/Au) as a back contact serves primarily to narrow the width of the inherent Schottky junction evident in CdTe solar cells (in our laboratory, Cu/Au has been used as a standard back contact). For efficient transport of carriers to and into the back contact, a hole transport layer (HTL) is desired with valence band edge comparable to that of CdTe (∼ -5.9 eV). Here, we report solution-processed nanocrystal (NCs) based thin films as HTLs in CdTe solar cells. The earth abundant materials we discuss include iron pyrite (FeS2), nickel-alloyed iron pyrite (NixFe1-xS2), zinc copper sulfide (ZnxCu1-xS) nanocomposites, and perovskite-based films. The FeS2 and NixFe1-xS2 NCs are synthesized by a hot-injection route, and thin films are fabricated by drop-casting, and spin-coating techniques using colloidal NCs. ZnxCu1-xS thin films are fabricated by chemical bath deposition. These NC-based thin films are applied and studied as the HTLs in CdTe devices. On using these materials, the device performance can be increased up to 10% compared to the standard Cu/Au back contact. Here, we discuss the benefits, challenges, and opportunities for these back contact materials in CdTe photovoltaics.

Resumen
Research subject. The Savabeisky sulfide copper-nickel ore occurrence, located in the central part of the Khengur (Central Pay-Khoy) gabbro-dolerite complex of the Pay-Khoy, within the Yugorsky Peninsula, located in the Far North-East of the European part of Russia, in the Arkhangelsk region, between the Barents and Kara Seas.Materials and methods. Samples of copper-nickel ores with noble metal mineralization were studied. Palladium tellurides and bismuthtellurides were characterized using optical and scanning electron microscopy, electron backscatter diffraction (EBSD), X-ray structural analysis and Raman spectroscopy.Results. Bismuthtellurides in the Paykhoysko-Vaigach-Yuzhnonovozemelskiy region – michenerite, merenskyite and unidentified palladium telluride of the kotulskite–merenskyite series with crystal formula Pd2(TeSbBi)3 – were found for the first time. The unit cell parameter of Pay-Khoy michenerite was calculated using X-ray diffraction analysis data: a = 6.638(2) Å. According to Raman spectroscopy, the palladium tellurides and bismuthtellurides of the Savabeisky ore occurrence were distinguished into 4 groups: Sb-kotulskite (does not contain Raman-active modes), unnamed PGM Pd2(TeSbBi)3 (bands in the range 95–103, 121–126 cm–1, obtained for the first time), Sb-merenskyite (band 126–135 cm–1), michenerite (bands with maxima 100 and 116 cm–1, obtained for the first time). The Kikuchi lines for michenerite and the mineral of the kotulskite–merenskyite series were obtained by the EBSD method.Conclusions. The diagnosis of palladium tellurides and bismuthtellurides is a rather complicated problem (wide variations in compositions, low hardness, small size, thin intergrowths of several individuals, the presence of impurities, etc.) affecting the determination of their mineral form and requiring an integrated approach. The Raman spectra of michenerite and unnamed PGM can be used as standards for the rapid identification of their natural forms, in contrast to EBSD, which requires improved sample preparation. The relatively high content of antimony in the ore minerals and noble metals minerals at the Savabeisky ore occurrence is the antimony metallogenic specificity characteristic of the entire Uralsko-Novozemelskiy province.
