SURFACTANT-ASSISTED SYNTHESIS OF BaTiO3 NANOPARTICLES BY MICRO-EMULSION METHOD
J. L. Gao, Y. Zhi, X. F. Ren, Y. H. Liu, College of Material Science and Engineering, Shenyang Ligong University, Shenyang, Liaoning, China. Barium titanate (B aTiO3) nanoparticles were successfully synthesized by using a surfactant-assisted method. The various processing parameters, namely, th e species of surfactant, reaction temperature and micro-emusion concentration had been varied, and th...
متن کاملSoft to Wet: Morphogenetic Engineering in Synthetic Biology
Synthetic biology is an emerging scientific discipline that promotes the standardized manufacturing of biological components without natural equivalents. It is currently in search of design principles to achieve a reliable and secure level of functionality from reusable biological parts, as exemplified by BioBricks. The goal is to create artificial living systems that can meet various needs in ...
متن کاملA novel method for "Wet" SEM.
Progress in the processing of wet tissues, without the need of fixation and complex preparation procedures, may facilitate the microscopic examination of tissues and cells. Microscopic examination of tissues is a central tool in clinical diagnosis as well as in diverse areas of research. The authors present the application of Wet SEM, a technology for imaging fully hydrated samples at atmospher...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
The Effect of Polyvinylpyrrolidone on the Formation of Copper Nanoplates in Wet-Chemical Reduction Method
In this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (II) sulfate as metal precursor and polyvinylpyrrolidone k-30 (PVP K-30) as surfactant agent. The reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. Characterization o...
