Cellular microvesicles and nanovesicles (exosomes) are involved in many disease processes have major potential as biomarkers. However, developments this area constrained by limitations the technology available for their measurement. Here we report on use of fluorescence nanoparticle tracking analysis (NTA) to rapidly size phenotype cellular vesicles. In system vesicles visualized light scattering using a microscope. A video is taken, NTA software tracks brownian motion individual calculates...
A simple extension of the reflection high-energy electron diffraction oscillation technique to vicinal surfaces provides a means studying surface diffusion during molecular beam epitaxial growth. The basis method is described and some preliminary results for Ga growth GaAs films with (001) 2×4 3×1 reconstructed are presented.
Y2O3:Eu nanocrystals in the size range 70–100 nm have been synthesized with a photoluminescence efficiency 10–20 % higher than that of commercial bulk material. The Figure shows nanocrystalline after firing precursor It can be seen crystals are structurally perfect, i.e., no defects found within crystal structure.
Abstract With mounting concerns over climate change, the utilisation or conversion of carbon dioxide into sustainable, synthetic hydrocarbons fuels, most notably for transportation purposes, continues to attract worldwide interest. This is particularly true in search sustainable renewable aviation fuels. These offer considerable potential since, instead consuming fossil crude oil, fuels are produced from using hydrogen and energy. We report here a protocol fixation by converting it directly...
We have carried out an experimental study of the As-stable $\mathrm{GaAs}(001)\ensuremath{-}c(4\ifmmode\times\else\texttimes\fi{}4)$ reconstruction using a combination molecular-beam epitaxy with reflection electron diffraction, angle-resolved photoemission, and surface-sensitive core-level photoemission. (The measurements were performed at Laboratoire pour l'Utilisation du Rayonnement Electromagn\'etique, Universit\'e Paris---Sud, F-91405 Orsay, France.) Apart from surface symmetry,...
Background: Common concerns of patients undergoing total knee arthroplasty (TKA) are whether they can continue with certain recreational and sporting activities or even commence new ones after the procedure. The present study was designed to determine preoperative postoperative activities, numbers participating time resume these activities. Methods: Between 1 2 years TKA, who had undergone 144 arthroplasties, were surveyed by postal questionnaire ascertain how affected their ability. Their...
Features in reflection high-energy electron-diffraction patterns arising from various types of surface disorder are discussed, with specific examples each. The relationship between (001)2\ifmmode\times\else\texttimes\fi{}4 and $(001)\ensuremath{-}c(2\ifmmode\times\else\texttimes\fi{}8)$ reconstructions, which frequently observed on III-V compound semiconductor surfaces, is explicitly demonstrated.
Through novel application of small-angle neutron scattering, we examined the fate silica nanoparticles (SiO(2)NPs) during simulated primary wastewater treatment, by measuring, in real time, colloidal behavior SiO(2)NPs (sewage). We effects surface functionality on SiO(2)NP wastewater, comparing both unfunctionalized (uncoated or "bare") and functionalized with a thin coating nonionic surfactant (Tween 20), which is widely used personal care household product formulations containing...
Few reports have been published about patient-perceived outcomes and return to sport following total knee arthroplasty (TKA) compared with unicompartmental (UKA). This article compares the two procedures using self-assessment questionnaires determine whether there was a difference in Oxford scores, sport, work. Patient-perceived of mini-incision UKA (Oxford; Biomet Inc, Warsaw, Ind) TKA were retrospectively reviewed at minimum 12 months after surgery. A 150 patients underwent 183 UKAs (mean...

Ultra-small superparamagnetic iron oxide nanoparticles were synthesized by co-precipitation of chloride salts with ammonia and then encapsulated thin (∼2 nm) layers silica. The particles have been characterized for size, diffraction pattern, surface charge, magnetic properties. This rapid economical synthesis has a number industrial applications; however, the silica-coated optimized use in medical applications such as resonance contrast agents biosensors, DNA capturing, bioseparation enzyme...
