A nanodiamond with a mean particle size of 4 nm, which was prepared by the detonation of a nanodiamond, has been characterized and used as a collector for tungstate in water samples. An aqueous solution of nanodiamond was found to be stable over the pH range from 3 to 10. Coagulation of the nanodiamond could be brought about by adding an electrolyte solution. The adsorption characteristics of n...

To resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies.  The assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process ...

Spray characteristics are the fundamental factors that affect droplet transportation downward, deposition, and drift. The downwash airflow field of Unmanned Aviation Vehicle (UAV) primarily influences deposition drift by changing spray characteristics. This study focused mainly on effect UAV nozzle position spatial distribution velocity distribution, which two To abovementioned characteristics,...

Laser based devices are ubiquitous in many fields which has resulted an increase ocular injuries from laser exposure. Glasses for protection available but contact lenses that block certain wavelengths could be a less bulky alternative. Here, we focus on developing lens protecting eyes accidental exposure to green by incorporation of gold nanoparticles exhibit local maximum absorbance as tunable...

It has been firmly established that in many teleosts the sympathetic nervous system contains cells whose activity causes aggregation of the pigment within the melanophores and therefore paling of the skin. In the minnow these W (whitening) fibres were shown by von Frisch (1911) to follow the pathways shown in Fig. iA; that is they pass from a centre in the hind-brain via the spinal cord to the ...

Nanoparticle formulations have been widely used in the drug delivery field. The majority of published articles dealing with nanoparticle formulations have focused on the use of freshly prepared nanoparticles, but not many deal with scale-up production of nanoparticles and their long-term preservation by freeze-drying. To date, little information is available on an effective freeze-drying proces...

Experimental catalytic activity measurements, diffuse reflectance infrared Fourier spectroscopy, and density functional theory calculations are used to investigate the role and dynamics of surface oxygen vacancies in CO oxidation with O2 catalyzed by Au nanoparticles supported on a Y-doped TiO2 catalyst. Catalytic activity measurements show that the CO conversion is improved in a second cycle o...

The aim of present study was to prepare human serum albumin (HSA) nanoparticle for drug delivery. These nanoparticles were prepared by desolvation method. The body distribution of colloidal drug delivery systems was mainly influenced by two physicochemical properties namely particle size and surface characteristics. The influence of several factors on the fabrication process including the pH va...

immunodiagnostic tests. The recent advances in polymer In this work the interaction of an a-CRP IgG protein with science have made it possible to produce uniform latexes functionalized latexes that have acetal groups on their surfaces with desired size and surface characteristics. Thus, it is possihas been studied. Two acetal latexes with similar amounts of ble to obtain latex particles with sp...
