The Fe( iii )-based MOF acted as a highly efficient and recyclable heterogeneous catalyst for hydrogenperoxide decomposition with simple retrieval from the reaction mixture.
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
The facile regioselective synthesis of the P(iii) substituted thiazol-2-thione 2 is presented. Reaction of 2 with hydrogenperoxide-urea, elemental sulfur and selenium resulted in P(v) chalcogenide thiazol-2-thiones 3-5. All compounds were characterized using (31)P, (1)H, (13)C NMR, IR and elemental analyses and, additionally, by the single-crystal X-ray diffraction technique. Oxidative desulfur...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
A facile enzyme-free hydrogenperoxide electrochemical sensorwas fabricated based onmultilayer ultrathin film containing Naphthol green B anions (NGB) and exfoliated nanosheets of Co–Al layered double hydroxide (LDH) via layer-by-layer self-assembly technique. The X-ray diffraction pattern indicates the superlattice structure of the filmwith repeating distance of 4.15nm; SEM and AFM images show ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
survey microbial decomposition leaf litter of salix sp. populus sp. robinia sp. in artificial stream
مطالعه اکولوژیک از سرچشمه رودخانه قره سو(سراب روانسر) در استان کرمانشاه واقع در غرب ایران در پائیز 1378 انجام شد، حداکثر دمای آب 20 درجه سانتی گراد بود، هنگام مطالعه دما در سرچشمه 18 سانتی گراد بود، مقدار عناصر شیمیایی آب اندازه گیری نشد. در این پژوهش لاشبرگ های درختی از بید، چنار، اقاقیا جمع آوری سپس توسط بخش هرباریوم دانشکده کشاورزی دانشگاه شناسایی شدند. وزن خاکستر خشک afdm در(نمونه برداری ...
