Release of Nano Particles when Handling Fumed Silica

08-Sep-2015 | Eberhard Schmidt, Chemical Engineering & Technology, 2015

Abstract The handling of dispersed solids may lead to undesirable release of particles. Size and quantity of the particles transferred into the gas depend on powder properties and the kind of stress acting on the bulk. This has to be taken into account concerning the requirements and the ...

Reducible Hyaluronic Acid–siRNA Conjugate for Target Specific Gene Silencing

17-Jun-2013 | Kitae Park; Jeong-A Yang; Min-Young Lee; Hwiwon Lee; Sei Kwang Hahn, Bioconjugate Chemistry, 2013

Despite wide applications of polymer–drug conjugates, there are only a few polymer–siRNA conjugates like poly(ethylene glycol) conjugated siRNA. In this work, reducible hyaluronic acid (HA)–siRNA conjugate was successfully developed for target specific systemic delivery of siRNA to the liver. The ...

A Simplified Approach to Modeling the Rate of Formation of Gas Hydrates Formed from Mixtures of Gases

01-Mar-2013 | Carlos Giraldo; Brij Maini; Raj Bishnoi; Matthew Clarke, Energy & Fuels, 2013

Experiments were conducted in a semibatch stirred tank reactor, equipped with an in situ particle size analyzer, to study the rate of formation of hydrates from mixtures of carbon dioxide and methane. Two gas mixtures of CO2 (1) + CH4 (2), one with x1 = 0.4 and the other with x1 = 0.6, were used ...

Effect of cosolvent NMP on properties of cationic fluorocarbon emulsifier-free emulsion

10-Nov-2012 | Chen Wang, Xiaorui Li, Peizhi Li, Colloid & Polymer Science, 2012

Cationic fluorocarbon emulsifier-free emulsion was prepared via a novel method of adding organic cosolvent N-methylpyrrolidone (NMP), which was characteristic of the reaction transferring from solution to emulsion polymerization system. The emulsion stability was analyzed by the coagulation and ...
