We provide here information on the distribution of copper, zinc, lead, gold, silver, barium, arsenic, antimony, mercury, selenium and tellurium in the Moore and Monte Negro high-sulfidation epithermal deposits in the Pueblo Viejo district, Dominican Republic. Moore and Monte Negro are funnel-shaped zones of advanced argillic alteration and precious-metal mineralization which extend to depths of...

One-dimensional selenium and tellurium under intense optical fields generate significant second-harmonic generation bulk photovoltaic effect.

A containment spray system is used to mitigate the source term from building environment as part of severe accident management actions. Tellurium one volatile fission products and many tellurium isotopes decay into iodine, which causes a threat public due its radiotoxicity build-up in thyroid gland. The removal efficiency model against species formed under conditions was investigated with exper...

Subnanosecond infrared pulses have been measured by nonc011inear secondharmonic generation in tellurium. The method is very practical because due to the high refractive index the fine tuning of the phase matching is easily obtained by rotating the crystal around the optic axis.

The distortions in the square tellurium nets long known to exist in the structures of the charge-density wave materials, RETe3, have been elucidated. The (Te2)1- nets contain polytelluride oligomers which propagate in a fashion incommensurate from the adjacent (RETe)+ sublattice. The new information sets the stage for a much deeper understanding of these systems.

Influence of water solutions with various pH and electrochemical treatment in cathode position on concentration charge carriers samples Cd x Hg 1-x Te x=0.2-0.3 is investigated. Cathodic cadmium-mercury-tellurium at small density current increases donors, high acceptors are formed. It supposed that hydroxyl groups create centers, introduce interstitial cadmium-mercury-tellurium. At for a long t...

Highly-flexible thermoelectric fabrics were fabricated based on a layered structure, composed of a thin active layer of self-assembled tellurium nanorods and a substrate layer of polyvinylidene fluoride. The resulting thermoelectric fabrics show a high room temperature power factor of 45.8 μW m(-1) K(-2), which opens a new avenue to fabricate highly-flexible sustainable energy sources.

Electrospinning and galvanic displacement reaction were combined to synthesize ultra-long hollow tellurium (Te) nanofibers with controlled dimensions, morphology and crystallinity by simply tailoring the electrolyte concentration applied. Within different morphologies of nanofibers, the branched Te nanostructure shows the greatest sensing performance towards NO2 at room temperature.

We propose a magnetic resonance force microscopy (MRFM)-based nuclear spin quantum computer using tellurium impurities in silicon. This approach to quantum computing combines well-developed silicon technology and expected advances in MRFM. Our proposal does not use electrostatic gates to realize quantum logic operations.

Abstract High-purity crystalline Tellurium has been investigated using positron lifetime spectroscopy technique in order to determine basic information missing the current experimental knowledge of annihilation field. Three different pairs samples have studied as-received state and, eliminate vacancy-type defects, after consecutive isothermal treatments at 300 °C. Lifetime corresponding bulk de...
