Both bioactive ion chemistry and nanoscale surface modifications are beneficial for enhanced osseointegration of endosseous implants. In this study, a facile synthesis approach to the incorporation of bioactive Ca2+ ions into the interlayers of nanoporous structures (Ca-nano) formed on a Ti6Al4V alloy surface was developed by sequential chemical and heat treatments. Samples with a machined surf...

Tumor-associated macrophages (TAMs) are key contributors to tumor development, accelerated invasion and metastasis, induction of immunosuppression. Targeted delivery immunomodulatory agents promote polarization TAMs may alleviate the immunosuppressive microenvironment. Calcium carbonate nanoparticles (CCN), which exhibit excellent biocompatibility, pH sensitivity, easy surface modification, hav...

Abstract Silicone rubber is an insulating material widely used in DC cable accessories. Its interface a weak area of insulation. Hydrated silica (SiO 2 ·H O) reinforcing agent commonly SR, and its main component SiO . Based on the theory nano-composite dielectric, four kinds composite silicone samples with different filler contents were prepared by taking as liquid matrix. The properties tested...

in the present investigation surface modification of silica nanoparticles by alumina was carried out by sol-gel process. fourier transform infrared (ftir) and x-ray fluorescence (xrf) confirmed the synthesis of silica and the surface modification as alumina is anchored to silica surface. field emission scanning electron microscopy (fesem) and transmission electron microscopy (tem) investigation...

Nano-structuring of the surface caused by adsorption of molecules or atoms and by the reaction of surface atoms with adsorbed species are reviewed from a chemistry viewpoint. Self-assembly of adsorbed species is markedly influenced by weak mutual interactions and the local strain of the surface induced by the adsorption. Nano-structuring taking place on the surface is well explained by the noti...

Due to the growing aging population of world, and as a result increasing need for dental implants prostheses, use titanium its alloys implant materials has spread rapidly. Although are considered best metallic biomedical applications, innovative technologies is necessary due sensitivity medical applications eliminate any potentially harmful reactions, enhancing implant-to-bone integration preve...

The helium effects in Chinese developed CN-G01 beryllium are important issues for its use nuclear energy systems. In this work, the samples were irradiated with ions to fluences of 5.0 × 1016 ions/cm2 1.0 1018 at room temperature and investigated by techniques scanning electron microscopy (SEM), transmission (TEM) nano-indentation. It was found that irradiation induced hardening nano-hardness i...

Abstract Implant therapy is a commonly based method of replacing missing teeth. A range physical, chemical, and biological modifications have been applied to the surface titanium implants improve their performance osseointegration outcomes. characteristics play an important function in several peri-implant cellular molecular mechanisms. Clinicians are placing dental with various roughness inclu...
