AU - Sierra-Alvarez,Reyes. AU - Field,Jim A.. PY - 2017/1/1. Y1 - 2017/1/1. N2 - According to the U.S. Department of Energy and the European Union, tellurium is a critical element needed for energy and defense technology. Thus methods are needed to recover tellurium from waste streams. The objectives of this study was to determine the feasibility of utilizing upflow anaerobic sludge bed (UASB) reactors to convert toxic tellurite (TeIV) oxyanions to non-toxic insoluble elemental tellurium (Te0) nanoparticles (NP) that are amendable to separation from aqueous effluents. The reactors were supplied with ethanol as the electron donating substrate to promote the biological reduction of TeIV. One reactor was additionally amended with the redox mediating flavonoid compound, riboflavin (RF), with the goal of ...
Lifton also briefly mentioned the militarys use of tellurium and selenium in solar energy conversion. Coincidentally, Phoenix-based First Solar Inc. which went public last fall, produces photovoltaic solar panels (ie, electricity producing panels) using cadmium tellurium as the absorption layer. First Solar says in their annual report that, "Cadmium tellurium…has the potential to deliver competitive conversion efficiencies with approximately 1% of the semiconductor material used by traditional crystalline silicon solar modules." This reduces the cost of solar panels, making them more competitive. [Note - in the interest of disclosure - I own stock in First Solar].. ...

Abstract : Tellurium has gained significant attention due to its photoconductivity, piezoelectricity, and thermo conductivityproperties. The aim of this study was to evaluate the effect of biofield energy treatment on thermal, physical and atomicproperties of tellurium powder. The tellurium powder was equally divided in two parts: control and treated (T). Thetreated part was subjected to Mr. Trivedis biofield energy treatment, whereas the control part was remained untreated.Subsequently, the control and treated samples were characterized using differential scanning calorimetry (DSC),thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy. TheDSC data showed that latent heat of fusion was decreased by 14.13, 21.90, and 5.55% in treated samples T1, T2, andT3, respectively as compared to the control. However, the melting temperature did not show any change in treatedsamples as compared to the control. The TGA data showed that the peak width ...

Organotellurium chemistry in chemistry describes the synthesis and properties of chemical compounds containing a carbon to tellurium chemical bond. Organotellurium chemistry was developed in the wake of organoselenium chemistry and, sharing the same group in the periodic table, both chemistries have much in common. The Te analogues of common organosulfur functional groups are known. Tellurols are unstable. Diorganomono- and ditellurides are the most commonly encountered organotellurium compounds. Telluroxides (R2TeO) are also known. Commonly used tellurium based reagents are hydrogen telluride, NaHTe, sodium telluride, and PhTeLi. Because Te is insoluble and polymeric, it is often not a useful precursor to organotellurium compounds, but it is attacked by hydride reducing agents: Te + 2LiBHEt3 → Li2Te + H2 + 2 BEt3 and organolithium compounds: Te + RLi → RTeLi One departure from S and Se chemistry, is the availability of the tetrachloride TeCl4. Tellurium tetrachloride reacts with alkenes and ...
The increasing use of products derived from nanotechnology has raised concern about their potential toxicity to aquatic life. This study sought to examine the comparative immunotoxicity of capped cadmium sulphide/cadmium telluride (CdS/CdTe) quantum dots (QDs) and possible impact of particle/aggregate size on two bivalves (Mytilus edulis and Elliptio complanata) and a fish (Oncorhynchus mykiss). The QDs were dispersed in sterile water and fractionated using a series of micro/ultrafiltration membranes of decreasing pore size: 450 nm, 100 nm, 50 nm, 25 nm, 100 kDa (6.8 nm), 30 kDa (4.6 nm), 10 kDa (3.2 nm) and 1 kDa (1.5 nm). The total concentrations of cadmium and tellurium were determined for the filtered material and for that retained on the filters (retentate). The immunotoxicity was determined by measuring cell viability and phagocytosis. Results revealed that nanoparticles retained on the ultrafilters had a higher Cd/Te ratio compared to the permeate fraction (ratio of 5 and 2 respectively) ...

In the event - as with all Lord Obreptions predictions - the Large Hydrangea Collider crashed when someone who was cutting peat on Benbecula cut through the power cable. This resulted in the discovery of 30 pieces of royal wedding souvenir crowns which had been hidden by Mary Queen of Scots after she had been involved in the Kirk OFields booby trap which killed her second husband (check citation re. Mary Queen of Scots biographies). These coins were submitted for research and it was discovered that a new element had been created and that the orginal Tellurium pieces had infact been transformed by a miracle to Templetonium with the assistance of 1 million pounds from a funding body which normally doles out cash to UK political, economic and humanities institutions. There was a lot of hand wringing, demands of proof, primary sourcing and in this special week of WHHW, claims and counter claims were made. The Concordat which we previously published spontaneously combusted and it has been agreed by ...

We aimed at establishing the optimal scan time for nuclear myocardial perfusion imaging (MPI) on an ultrafast cardiac gamma-camera using a novel cadmium-zinc-telluride (CZT) solid-state detector technology. METHODS: Twenty patients (17 male; BMI range, 21.7-35.5 kg/m(2)) underwent 1-d (99m)Tc-tetrofosmin adenosine stress and rest MPI protocols, each with a 15-min acquisition on a standard dual-detector SPECT camera. All scans were immediately repeated on an ultrafast CZT camera over a 6-min acquisition time and reconstructed from list-mode raw data to obtain scan durations of 1 min, 2 min, etc., up to a maximum of 6 min. For each of the scan durations, the segmental tracer uptake value (percentage of maximum myocardial uptake) from the CZT camera was compared by intraclass correlation with standard SPECT camera data using a 20-segment model, and clinical agreement was assessed per coronary territory. Scan durations above which no further relevant improvement in uptake correlation was found were ...
In the last two decades, semiconductor quantum dots small colloidal nanoparticles have garnered a great deal of scientific interest because of their unique properties. Among nanomaterials, CdTe holds special technological importance as the only known II-VI material that can form conventional p-n junctions. This makes CdTe very important for the development of novel optoelectronic devices such as light-emitting diodes, solar cells, and lasers. Moreover, the demand for water-compatible light emitters and the most common biological buffers give CdTe quantum dots fields a veritable edge in biolabeling and bioimaging.

Paratellurite, α-TeO2, converts at high pressure into the β-, tellurite form.[7] Both the α-, (paratellurite) and β- (tellurite forms) contain four coordinate Te with the oxygen atoms at four of the corners of a trigonal bipyramid. In paratellurite all vertices are shared to give a rutile-like structure, where the O-Te-O bond angle are 140°. α-TeO2 In tellurite pairs of trigonal pyramidal, TeO4 units, sharing an edge, share vertices to then form a layer.[7] The shortest Te-Te distance in tellurite is 317 pm, compared to 374 pm in paratellurite.[7] Similar Te2O6 units are found in the mineral denningite.[7] TeO ...
Tinsdale medium supports the growth of all species of Corynebacterium while inhibiting the growth of normal inhabitants of the upper respiratory tract. Potassium tellurite from the supplement inhibits all gram-negative bacteria and most of the upper respiratory tract normal flora. L-cystine and sodium thiosulphate form the H₂S indicator system. Black coloration of the colonies results from tellurite reductase activity, resulting in the reduction of tellurium, while the brown halos indicate cystinase activity. Only C. diphtheriae and C. ulcerans gives black colonies with distinctly outlined halo. Other diphtheroids, staphylococci, and some streptococci may also reduce tellurite, although halos around the colonies are not generally present.. Peptic digest of animal tissue provides nitrogenous compounds and agar is for the solidification of the medium. ...
Ga-doped CdTe polycrystalline thin films were successfully electrodeposited on glass/fluorine doped tin oxide (FTO) substrates from aqueous electrolytes containing cadmium nitrate (Cd(NO3)2⸱4H2O) and tellurium oxide (TeO2). The effects of different Ga-doping concentrations on the CdTe:Ga coupled with different post-growth treatments were studied by analysing the structural, optical, morphological and electronic properties of the deposited layers using X-ray diffraction (XRD), ultraviolet-visible spectrophotometry, scanning electron microscopy, photoelectrochemical cell measurement and direct-current conductivity test respectively. XRD results show diminishing (111)C CdTe peak above 20 ppm Ga-doping and appearance of (301)M GaTe diffraction above 50 ppm Ga-doping indicating the formation of two phases; CdTe and GaTe . Although, reductions in the absorption edge slopes were observed above 20 ppm Ga-doping for the as-deposited CdTe:Ga layer, no obvious influence on the energy gap of CdTe films ...
Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. It rarely occurs in its elemental state in nature, or as pure ore compounds. Selenium (Greek σελήνη selene meaning "Moon") was discovered in 1817 by Jöns Jakob Berzelius, who noted the similarity of the new element to the previously-known tellurium (named for the Earth).. Selenium is found impurely in metal sulfide ores, where it partially replaces the sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores, most often during copper production. Minerals that are pure selenide or selenate compounds are known, but are rare. The chief commercial uses for selenium today are in glassmaking and in pigments. Selenium is a semiconductor and is used in photocells. Uses in electronics, once important, have been mostly supplanted by silicon semiconductor ...
