The purpose of this study was to evaluate the potential of new carboxylated multi-block copolymer of lactic acid and ethylene glycol (EL14) for nanoparticle (NP) formation and their ability to deliver high molecular weight hydrophobic drug--cyclosporine A (CsA). CsA-loaded EL14 NPs were compared with traditional poly(lactide-co-glycolide) (PLGA) NPs, both prepared by emulsion-diffusion-evaporat...

A method to prepare novel organic-inorganic hydrophobic nanocomposite films was proposed by a site-specific polymerization process. The inorganic part, the core of the nanocomposite, is a ternary SiO₂-Al₂O₃-TiO₂ nanoparticles, which is grafted with methacryloxy propyl trimethoxyl silane (KH570), and wrapped by fluoride and siloxane polymers. The synthesized samples are characterized by transmis...

Abstract Surfaces covered with micro, nano and multiscale topographies are the subject of significant interest due to their ice-repellency properties in last decade. Ultrafast laser processing is becoming a widely used clean manufacturing technique fabricate ordered on metallic surfaces over relatively large areas. In this work, single-tier two-tier were fabricated stainless steel one-step femt...

In this work, we investigate the fabrication of stainless-steel substrates decorated with laser-induced periodic surface structures (LIPSS) both hydrophilic and hydrophobic wettability through different post-processing manipulation. carrying out these experiments, have found that while a CO2-rich atmosphere during irradiation does not affect final wettability, residence in such an after indeed ...

The colloidal properties of suspended metal-organic frameworks (MOFs) are critical for device fabrication and application. Herein, van der Waals attractive, electric double layer repulsive, steric repulsive forces a native encapsulated MOF quantified the first time. attractive were investigated by conducting environmental ellipsometric porosimetry (EEP) spectroscopic ellipsometry (SE) on submic...

THE EFFECT OF CALCINATION TEMPERATURE TO COMPOSITECHARACTERISTICS TiO2SiO2 NANOPARTICLE. Self-cleaning material is a that utilizes the photocatalytic property to degrade organic and inorganic compounds with help of UV light. One materials have good TiO2, causes TiO2 be amphiphilic: becomes hydrophilic when there light hydrophobic no The can improved addition buffer such as SiO2. nanoparticle wa...

The effectiveness of therapeutic monoclonal antibodies (mAbs) is governed not only by their bioactivity, but also by their biophysical properties. Assays for rapidly evaluating the biophysical properties of mAbs are valuable for identifying those most likely to exhibit superior properties such as high solubility, low viscosity and slow serum clearance. Analytical hydrophobic interaction chromat...

Objective: Formulation and evaluation of clobetasol-17-propionate-loaded carboxymethyl chitosan nanoparticle. Psoriasis is a chronic skin disorder caused due to the autoimmune factors. It has detrimental psychological physiological impact on patients emergence apparent skin. The systemic therapy with anti-psoriatic drugs such corticosteroids, immunosuppressant, gene suppressors causes severe si...

As one of the most prominent anticake agent, SiO2 nanoparticle synthesis method was modified and investigated for a better understanding fabrication process. Hence, tetraethoxysilane presursor subjected to varying procedures such as concentration change surface modification ligants. pH value all other material composition kept same by implying sol-gel reaction mechanism, basic catalysis tempera...

The influence of pH on the sorption of pentachlorophenol (PCP) onto three organic amendments, char, humic acid (HA) and peat, and the effect of organic amendments on PCP sorption to three kinds of soils were evaluated. The sorption of PCP on these sorbents fitted the Freundlich model well, suggesting that PCP sorption isotherms were nonlinear with exponential coefficient (N) value lower than 1....
