Capillary electrophoretic determination of selenocyanate and selenium and tellurium oxyanions in bacterial cultures.
A simple capillary zone electrophoretic method for the determination of biospherically important oxyanions of selenium (Se) and tellurium and another Se-containing anion, selenocyanate, has been developed. The method uses direct UV absorption detection. Time course experiments with time slices as short as 6 min are possible. This method's detection limits and linear range compare well with othe...
متن کاملOscillator strengths for neutral selenium and tellurium
Oscillator strengths for excitations of neutral selenium and tellurium from the ground state are calculated using a semiempirical analytic independent-particle-model. The results are compared to experimental and theoretical data.
متن کاملPreparation of carbon nanotubes by DC arc discharge process under reduced pressure in an air atmosphere
Carbon nanotubes (CNTs) were grown using a DC arc discharge process in an air atmosphere and relevant process parameters were investigated. ithout using an inert gas, multi walled carbon nanotubes could be synthesized in the deposit area of the cathode even in an air atmosphere, but ingle walled carbon nanotubes were not detected in the soot area despite using the same process conditions as in ...
متن کاملWeyl Node and Spin Texture in Trigonal Tellurium and Selenium.
We study Weyl nodes in materials with broken inversion symmetry. We find based on first-principles calculations that trigonal Te and Se have multiple Weyl nodes near the Fermi level. The conduction bands have a spin splitting similar to the Rashba splitting around the H points, but unlike the Rashba splitting the spin directions are radial, forming a hedgehog spin texture around the H points, w...
متن کاملrisk taking in english to persian translation process by novice iranian translators
این پژوهش به بررسی ریسک پذیری مترجمان تازه کار در طی فرآیند ترجمه از زبان انگلیسی به فارسی می پردازد. پژوهش درباره مترجمان به عنوان اولین خواننده متن مبدا از اهمیت به سزایی برخوردار است. مترجمان تازه کار (و حرفه ای) در طی فرآیند ترجمه با مشکلات متعددی روبرو می شوند که باعث عدم اطمینان آنها از متن ترجمه شده می شود. با توجه به اینکه عدم اطمینان به انجام ریسک منتهی می شود، هدف این پژوهش بررسی کیفی...
