Demonstration of a robust, tellurium-free thermoelectric module for near-room-temperature applications with high conversion efficiency 8.5% and maximum cooling 72 K.

Three different elements, Silicon, Selenium, and Tellurium, are ion-implanted in Gallium arsenide to form a conducting layer that serves as back-gate molecular beam epitaxy (MBE) overgrown two-dimensional electron gas (2DEG). While the heavy ion Tellurium creates too many damages gallium layer, both Silicon Selenium show promising results combined with MBE-grown high-quality 2DEGs. Similar 2DEG...

We report on a self-organized process initiated potassium-tungsten-tellurite glass surface under repetitive femtosecond laser irradiation in regime where cumulative effects lead to localized melting. Specifically, we show that periodic patterns consisting of parallel nanoplanes perpendicular the polarization are forming and extending beyond zone direct exposure. Examination modified regions rev...

Seven species of obligately aerobic photosynthetic bacteria of the genera Erythromicrobium, Erythrobacter, and Roseococcus demonstrated high-level resistance to tellurite and accumulation of metallic tellurium crystals. High-level resistance without tellurite reduction was observed for Roseococcus thiosulfatophilus and Erythromicrobium ezovicum grown with certain organic carbon sources, implyin...

We propose a magnetic resonance force microscopy (MRFM)-based nuclear spin quantum computer using tellurium impurities in silicon. This approach to quantum computing combines the well-developed silicon technology with expected advances in MRFM. PACS: 03.67.Lx, 03.67.-a, 76.60.-k

Iron telluride nanorods (FeTe NRs, length 45 ± 11 nm) prepared from tellurium nanowires (Te NWs, length 785 ± 170) have been used to detect H(2)O(2) and glucose with a limit of detection (LOD) of 55 nM (linear range = 0.1-5 μM) and 0.38 μM (linear range = 1-100 μM) respectively.

Ionic liquids are shown to be good solvents for elemental sulfur, selenium, phosphorus and tellurium, and can be designed to maximise the solubility of these elements. The presence of the [S(3)](*-) radical anion in diluted solutions of sulfur in some ionic liquids has been confirmed, and is the origin of their intense blue colour (cf. lapis lazuli).

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...
