The production of pure silver in nanoparticle size has opened new dimensions the clinical use this precious metal. We and others have demonstrated previously that nanoparticles (nAg) possess efficient antimicrobial activity. Herein we show they may also significant anti-inflammatory effects a postoperative peritoneal adhesion model. This finding provides further insight into biological actions nAg as well potentially novel therapy for adhesions surgery.With advent nanoscience, can now be...
Abstract Nano‐fibrous felts (nano‐felts) of carbide‐derived carbon (CDC) have been developed from the precursor electrospun titanium carbide (TiC) nano‐felts. Conformal transformation TiC into CDC conserves main features including high interconnectivity and structural integrity; TiC‐CDC nano‐felts are mechanically flexible/resilient, can be used as electrode material for supercapacitor application without addition any binder. After synthesis through chlorination at 600 °C, nano‐fibers show...
In order to verify the actual effect of an exponential-doping structure on cathode performance, has been applied preparation transmission-mode GaAs photocathode via molecular beam epitaxy technique. Compared with uniform-doping photocathode, activation and spectral response results show that can achieve a higher photoemission capability. addition, based revised quantum yield equations, performance parameters such as electron average transport length escape probability are obtained, which...
The drug discovery and development process is greatly hampered by difficulties in translating vitro potency to vivo efficacy. Recent studies suggest that the long-neglected drug-target residence time parameter complements classical affinity parameters (KI, Kd, IC50, or EC50) a better predictor of Compounds with long are often more efficacious vivo. impact, however, on efficacy remains controversial due experimentally determining target occupancy during treatment. To tackle this problem, an...
This study reports an approach for synthesis of graphitic carbon nanocages (CNCs) via pyrolysis ethanol with dissolved iron carbonyl at temperatures from 600 to 900 °C. The in situ formed Fe catalyst and template enabled the generation formation layers on surface. With removal template, hollow CNCs were obtained have a fine size 30−50 nm large surface area 400−800 m2/g. also became dispersible water without aggregation settling after several months through HNO3 treatment. As example...
Scales of aligned single-crystalline SiC nanowires (SiCNWs) arrays with very small diameter were synthesized by a simple thermal evaporation ZnS and carbon on silicon wafer. The as-received SiCNWs possess uniform size distribution centered at approximately 8.0 nm, even minimum 3.0 nm. highly oriented usually grew along [111] direction clean surface, thin oxide shell, quantity stacking faults. A crystalline tube-like nanostructure is also obtained. optical properties, including...
A novel self-cleaning glass was successfully achieved by coating macroscopical SiC nanowires (SiCNWs) in tetraethyl orthosilicate (TEOS) solution. The water contact angle (CA) high, up to approximately 160 degrees, and the sliding low, down 5 when SiCNWs were coated through 10 cycles, with a high roughness Ra of 1928.9 nm. High chemical stability obtained even after immersing sample for 14 days (336 h). calculated data using nano/micropillar composite structure model displayed beneficial...
Abstract Nanostructured graphitic carbons have widespread applications. However, the synthesis of such materials with a high surface area is still great challenge. In this study, we demonstrate new approach for improving area. Graphitic carbon nanocages (CNCs) are prepared by spray pyrolysis ethanol dissolved iron carbonyl at temperature. Ammonium thiocyanate added to form sulfide as less active catalyst and template dissolution precipitation than single‐phase Fe. This addition leads an...

The topographic roughness chemical modification CF 2/CF 3 groups...
Abstract Gold nanoparticle‐decorated carbon nanotubes (CNTs) are used to study intracellular environments in situ using surface‐enhanced Raman spectroscopy (SERS). CNTs decorated with gold nanoparticles and assembled onto the tips of pulled glass capillaries form a SERS‐enabled endoscope. The sub‐micrometer size high mechanical strength endoscope make it possible penetrate cell membrane for probing remain positioned inside during lengthy SERS measurements without causing damage cell.

Obtaining higher quantum efficiency and more stable GaAs photocathodes has been an important developmental direction in the investigation of photocathodes. One significant approach to this problem is improve electron diffusion length. We put forward investigate exponential doping mode photocathode. It was proved by theoretical experimental results that, because structure favor forming a directional constant built-in electric field, drift length cathode material can accordingly be enhanced....
