synthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
A Simultaneous Magneto-Dielectric Phase Transition in RbCoBr3
We have modeled magneto-dielectric phase transitions in ABX3-type layered triangular lattice compounds. The model consists of a spin system (magnetic transition) and a lattice system (dielectric transition). Magnetic exchange interactions are supposed to change with a relative position between two spins. This assumption produces an effective coupling between the lattice and the spin. Applying t...
متن کاملPhase diagram of microtubules.
The protein tubulin is found in every cell of every living organism (with the exception of bacteria ) [1]. In the presence of guanosine-tri-phosphate (GTP) and magnesium ions (Mg +), tubulin-GTP complexes form [2] and aggregate [3] into long, hollow cylinders called microtu bules. Microtubules are about 25 nm in outer diameter, incorporate 1625 tubulin dimers per micrometer of their length [4] ...
متن کاملPhase Diagram of the TbBr3-KBr Binary System
The phase equilibrium of the TbBr3-KBr has been established by Differential Scanning Calorimetry. This system has the three compounds K3TbBr6, K2TbBr5, and KTb2Br7 and two eutectics located at (xTb = 0.163 (885 K) and (xTb = 0.433 (697 K). K3TbBr6 undergoes a solid-solid phase transition at 691 K and melts congruently at 983 K with the corresponding enthalpies 8.0 and 48.0 kJ mol−1. K2TbBr5 mel...
متن کاملPhase Diagram of LixFePO4
The phase diagram for LixFePO4 has been determined for different lithium concentrations and temperatures. The two lowtemperature phases, heterosite and triphylite, have previously been shown to transform to a disordered solid solution at elevated temperatures. This disordered phase allows for a continuous transition between the heterosite and triphylite phases and is stable at relatively low te...
