using of colloids and polymeric microparticles are gradually increasing. it is observed that thepositive effects of particles stems in both traditional applications such as column pickings,coatings and paints to more recent technologies in diagnostics, drug delivery and optical devicesare well documented. this review focuses on importance of colloids and covers theirapplications on three level:...
We investigated the influence of tetrahydrofuran (THF) addition on the structure of poly(1,2-butadiene-b-ethylene oxide) [PB-PEO] micelles in aqueous solution. Our studies showed that while the micelles remained starlike, the micelle core-corona interfacial tension and micelle size decreased upon THF addition. The detailed effects of the reduction in interfacial tension were probed using contra...
Stable metal anode cycling for high energy density batteries can be realized through modification of electrolyte composition and optimization formation protocols, i.e., electrode interphase preconditioning conditions. However, the relationship between these electrochemical performance is still unclear due to a lack molecular level understanding electric double layer (EDL) changes with two param...
Cosolvent effect on morphogenic changes of self-assembled aggregates from biodegradable polylactones
The solvent variation effect on the self-assembly phenomenon is discussed in this article. Two different biodegradable backbones of same community (polycaprolactone and polylactide) were selected to visualize morphological changes upon treatment solvents/cosolvents. curiosity was observe if change occurred only with solvents or it assisted also. Tetrahydrofuran, acetonitrile 1,4 dioxane used as...
Graft copolymer composed hyaluronic acid (HA) and poly(D,L-lactide-co-glycolide) (PLGA) (HAgLG) was synthesized for antitumor targeting via CD44 receptor of tumor cells. The carboxylic end of PLGA was conjugated with hexamethylenediamine (HMDA) to have amine end group in the end of chain (PLGA-amine). PLGA-amine was coupled with carboxylic acid of HA. Self-assembled polymeric micelles of HAgLG ...
