Poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. The aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (PMECA) particles containing 5-aminosalicylic acid (5-ASA). PMECA particles were prepared using the inverse emulsification...

Particles stabilize fluid interfaces. In particular, oil/water Pickering emulsions undergo limited coalescence, yielding droplets of smaller size as the amount particles is increased. Herein, we studied effect hydrophobic nanoparticles (<10 nm, alkyl-coated) on submicronic (ca 100 nm) formed in an Ouzo system. We investigated thoroughly water/tetrahydrofuran (THF)/butylated hydroxytoluene (BHT)...

A protocol for measuring polydispersity of concentrated polymer solutions using dynamic light scattering is described. Dynamic light scattering is a technique used to measure the size distribution of polymer solutions or colloidal particles. Although this technique is widely used for the assessment of polymer solutions, it is difficult to measure the particle size in concentrated solutions due ...

Nano-additives blended water-diesel emulsion fuel is the alternative fuel for compression ignition (CI) engine that reduce the NOx emission and at the same time increase the brake thermal efficiency due to combined effect of nanoparticles and micro explosion phenomenon of water diesel emulsion. This review paper addresses emulsion, emulsion types, micro-explosion phenomenon of water-diesel emul...

introduction : flavors play an important role in consumer satisfaction and influence further consumption of foods. most available aroma compounds are produced via chemical synthesis or extraction. foodstuffs containing synthetic flavor in many cases are avoided, because the consumers suspect that these compounds are toxic or harmful to their health. recently, the market of flavors is focused in...

Three commercial silicone emulsions with different functional groups i.e., quat-silicone micro-emulsion (<40 nm particle size), amino-silicone macro-emulsion (110 nm), and silicone macro-emulsion with alkylmodified side groups (740 nm) were used to protect wood samples against fungal decay. The addition of the emulsions to an agar growth medium revealed that all three silicone formulations inhi...

Micro-scale optical components capable of on-demand reconfiguration of their internal morphology and composition would enable unprecedented control of light propogation on the microscale. Double emulsions formed from immiscible hydrocarbons and fluorocarbons offer a promising platform as reconfigurable micro-optical lenses. These droplet-based lenses can be reconfigured to strongly focusing, ne...
