Imaging of surface adsorbed molecules is investigated as a novel detection method for matter wave interferometry with fluorescent particles. Mechanically magnified fluorescence imaging turns out to be an excellent tool for recording quantum interference patterns. It has a good sensitivity and yields patterns of high visibility. The spatial resolution of this technique is only determined by the ...

Films of thickness 3 mm containing nanosized metal particles of iron, nickel and copper respectively were grown on a Corning glass slide using a sol-gel technique. The particle sizes had values in the range 6.8 to 20.1 nm. Optical absorption characteristics of different specimens were studied over the wavelength range 230 to 830 nm. An absorption maximum was observed at wavelength varying from ...

Recently, nanoporous fibers have been caught much attention as the most promising material in nanotechnology. To our knowledge, nanoporous materials have extremely high surface area and are widely used in different fields, such as filtration, radiation protection, catalysis, sensors, tissue engineering, and drug delivery [1-2]. Electrospinning is an effective method, which can fabricate polymer...

Nanocomposite SiOx particles have been produced by a single step plasma spray physical vapor deposition (PS-PVD) through rapid condensation of SiO vapors and the subsequent disproportionation reaction. Core-shell nanoparticles, in which 15 nm crystalline Si is embedded within the amorphous SiOx matrix, form under typical PS-PVD conditions, while 10 nm amorphous particles are formed when process...

Prosthetic meshes used for hernioplasty are usually complicated with chronic pain due to avascular fibrotic scar or mesh shrinkage. In this study, we developed a tissue-engineered mesh (TEM) by seeding autologous bone marrow-derived mesenchymal stem cells onto nanosized fibers decellularized aorta (DA). DA was achieved by decellularizing the aorta sample sequentially with physical, mechanical, ...

The Raman spectroscopy of pharmaceutical cocrystals based on caffeine and oxalic acid in nanosized pores of mesoporous silica has been demonstrated at various molar amounts. The Raman peak shifts of caffeine molecules express the existence of pharmaceutical cocrystals in mesoporous silica. The molar amount dependence of the peak shifts describes that caffeine and oxalic acid cocrystallized on t...

Background: Photocatalytic air purifiers based on nano-titanium dioxide (TiO2) visible light activation provide an efficient solution for removing and degrading contaminants in air. The potential detachment of TiO2 particles from the purifier to indoor could cause a safety concern. A release was measured one commercially availabl...

The paper is devoted for a solution of indoors fires prevention at early stage by determination H2 (fire precursor gas) in air using semiconductor sensor. A material based on Pt-containing nanosized tin dioxide with an average particle size 10–11 nm obtained via sol–gel method was created gas sensitive layer the developed sensor has high sensitivity to micro concentration, wide range its detect...

In order to efficiently deliver anticancer agents to tumors, biocompatible nanoparticles or bioconjugates, including antibody-drug conjugates (ADCs), have recently been designed, synthesized, and tested, some even in clinical trials. Controlled delivery can be enhanced by changing specific design characteristics of the bioconjugate such as its size, the nature of the payload, and the surface fe...
