The bulk production of polymeric nanofibers is important for fabricating high-performance, nanoscale materials. Rotary jet spinning (RJS) enables the mass production of nanostructured fibers by centrifugal forces but may result in inconsistent surface morphologies. Because nanofiber performance is dependent upon its surface features, we asked which parameters must be optimized during production...

We present a novel process to encapsulate indocyanine green (ICG) in liposomal droplets at high concentration for potential applications in image-guided drug delivery. The microencapsulation process follows two consecutive steps of droplet formation by liquid-driven coaxial flow focusing (LDCFF) and solvent removal by oil phase dewetting. These biocompatible lipid vesicles may have important ap...

Si recycling from powder waste is of great significance to the production profits and alleviate hazardous effects on ecological environment. Solvent refining an effective way reproduce solar-grade silicon (SoG–Si) by reusing waste. Herein, a Si–Sn–Cu ternary solvent with Zr-assisted method was proposed make full use high activity coefficients B strong affinity Zr. The at different compositions ...

The first nitrate anion templated assembly of an interlocked molecular architecture is demonstrated through the preparation of a [2]rotaxane. Removal of the discrete nitrate anion template from the [2]rotaxane reveals an interlocked host system capable of strong and selective recognition of nitrate, in aqueous-organic solvent mixtures, over a range of more basic mono-charged oxoanions.

phenomena came from industrial chemistry, and diaJc=Qf·Cb·S lysers were designed to be ideal counter-current being in ideal conditions: S=1–s, where s is the exchangers [2]. Only later was convection used in reflection coefficient of the membrane. These definiclinical practice, showing potential depurative advanttions present convection and diffusion as two separate ages [3,4]. At first, ultraf...

This paper presents results of investigations on physicochemical treatment of vegetable oil refinery wastewater (VORW), namely acid and technological wastewater. The study has shown that VORW has a varying high pollution load (organic matter, sulfates, phosphates and chlorides) and the removal of these pollutants from acid wastewater was more effective than that from technological wastewater; t...

BACKGROUND s/aims: Staining of internal limiting membrane with indocyanine green (ICG) has been reported to be associated with postoperative atrophic retinal pigment epithelium (RPE) change. Here the authors examined whether removing sodium from the solvent reduces ICG induced RPE cytotoxicity. METHODS Human RPE cells were exposed to ICG (0.25 and 0.025 mg/ml) reconstituted with balanced salt...

Aim: To evaluate the solvency of chloroform and eucalyptol for gutta percha removal in re-treatment. MethodologyA total of 40 extracted human maxillary single rooted teeth were selected. Canal preparation was carried out by the sequential use of Kfiles up to size 30 at working length and then divided into one control group(n=10)that is group I and three experimental groups II,III,IV (n=10 each)...

Context Endodontic retreatment is performed in teeth with endodontic failures. The main goal of retreatment is cleaning and shaping of the root canal with removal of old root filling material. Hand instruments and rotary instruments are mainly used for removing this filling material. Aim of Study To compare the relative efficacy of three rotary instrumentation systems for removal of gutta-per...

We describe the utilization of indocyanine green (ICG) dye to facilitate combined/en bloc removal of epiretinal membranes (ERM) along with internal limiting membranes (ILM). The method utilizes a highly diluted preparation of ICG in dextrose water solvent (D5W). Elimination of fluid air exchange step facilitating staining in the fluid phase and low intensity lighting help minimize potential ICG...
