Titanium is used worldwide to make osseointegrable devices. The favorable characteristics that make this material desirable for implantation are i) its mechanical properties and ii) its biocompatibility. The latter has been demonstrated by in vivo studies with animal models and clinical trials over a forty-year period. However, the exact genetic effect of the titanium layer on cells is still no...

Highly active and stable substrates for surface-enhanced Raman scattering (SERS) can be fabricated by using colloidal crystals to template gold nanoparticles into structured porous films. The structure-dependent performance of these SERS substrates was systematically characterized with cyanide in continuous flow microfluidic chambers. A matrix of experiments was designed to isolate the SERS con...

Structural disintegration or the loss of accessible surfaces of functional nanostructures due to processes involving mass transport (e.g. sintering) is a serious problem for any application of these materials at elevated temperatures, like in heterogeneous catalysis or chemical sensing. Phases with low sintering temperatures, e.g. some metals or metal oxides like zinc oxide (ZnO), are very sens...

Adrenomedullin (ADM) is a bioactive regulatory peptide that affects migration and proliferation of diverse cell types, including endothelial cells, smooth muscle cells, and osteoblast-like cells. This study investigated the effects of sustained release of ADM on the modulation activity of osteoblasts and vascular endothelial cells in vitro. Chitosan microspheres (CMs) were developed for ADM del...

background: nowadays, extensive technological advancements have made it possible to use nanopaints which show exciting properties. in ir iran excessive radon levels (up to 3700 bq m–3) have been reported in homes located in radon prone areas. over the past decades, concerns have been raised about the risk posed by resi- dential radon exposure. objective: this study aims at investigating the eff...

Cellulose insulation paper is the main component of oil-paper systems in oil-immersed transformers. However, poor thermal conductivity and stability cellulose can lead to ageing. It critical address this issue by improving performance cellulose, nano-SiC-modified models were established molecular simulation, while nano-SiC composite papersheets prepared based on simulation results, effects diff...
