ZnO and Al-doped ZnO thin films were deposited on ceramic substrate by using an asymmetric bipolar pulsed-DC magnetron sputtering system under Ar atmosphere. Compacted ZnO powder and ZnO:Al 2 O 3 premixed powder in copper supports were used as sputtering targets for the deposition of ZnO and Al-doped ZnO thin films, r…
We report on the loading and release of curcumin (a hydrophobic polyphenol with anti-inflammatory and anti-bacterial properties) from polyelectrolyte multilayers composed of poly(diallyldimethylammonium chloride) (PDADMAC) and poly(sodium 4-styrenesulfonate) (PSS). We have used the in situ techniques of attenuated tot…
The coating of an active drug, 6-mercaptopurine, into the iron oxide nanoparticles-polyethylene glycol (FNPs-PEG) in order to form a new nanocomposite, FPEGMP-2, was accomplished using coprecipitation technique. The resulting nanosized with a narrow size distribution magnetic polymeric particles show the superparamagn…
The market for rare-earth elements (REEs) and REE catalysts is analyzed. Essential data on the REE deposits in Russia and the world are given. The use of REEs is analyzed with emphasis on the production of magnets and catalysts. Some data on the fields of the application of REE catalysts, e.g., the purification of veh…
Rare earth elements as high sensitive labels to identify and monitor nanomaterials fate following manipulation.
The anodic dissolution of API X70 pipeline steel in Arabian Gulf seawater (AGSW) was investigated using open-circuit potential (OCP), electrochemical impedance spectroscopy (EIS), cyclic potentiodynamic polarization (CPP), and current-time measurements. The electrochemical experiments revealed that the X70 pipeline st…
We report the field effect properties of lithographically fabricated FET with as-prepared graphene quantum dots (GQDs) and hydrazine treated GQDs as channel material. GQDs of 4.5 ± 0.55 nm average diameter are synthesised via an electrochemical approach using multiwalled carbon nanotubes (MWCNTs) as precursor. After t…
Metal nanoparticles functionalized with self-assembled monolayers of ligands terminated in charged groups constitute a unique class of nanoscopic polyions – or “nanoions” in short – capable of assembling into higher-order structures.
Because coining dies are consumables, most of mints have adopted the hard surface coating on coining dies in order to increase the wear resistance of them. Even though coining dies for “proof coins” are coated by Cr-plating, they have especially short life time. Instead of Cr-plating, we tried to apply Diamond-Like Ca…
With the emergence of Nanotechnology, there has been remarkable improvement in the field of drug delivery system over the past decade. Nanotechnology in drug delivery system is an upcoming field and significant research has been conducted in this regard. It has been able to overcome some limitations encountered with t…
This paper describes the development of a post combustion carbon capture process from lab-scale to large-scale, with special focus on the validation of the scale-up with pilot plant tests. Important features like separation efficiency, solvent stability towards stress (caused e.g. by heat and oxygen) and reaction mech…
The effect of Cu dissolution during pulse electrodeposition process on the generation of high density nanoscale twin structure was investigated. During off-time, the density of nuclei was reduced by acidity of electrolytes. The reduction in the density of nuclei could suppress the formation of nanocrystalline structur…
This paper provides a brief overview of investigations that have been carried out on the tribological properties of polysaccharides. Much of the work into long chain carbohydrates focuses on adhesion due to the propensity of these molecules to form hydrogen bonds. Polysaccharides play an important role in bioadhesion,…
A thiol-selective 2-methyl-3-phenacrylate scaffold with spatiotemporal control over delivery of a cargo is reported. The half-lives of decomposition could be tuned from 30 min to 1 day and the scaffold's utility in thiol-inducible fluorophore release in cell-free as well as within cells is demonstrated.
Vertically aligned, hollow nanotubes of CdSe are grown on fluorine doped tin oxide (FTO) coated glass substrates by ZnO nanowire template-assisted electrodeposition technique, followed by selective removal of the ZnO core using NH4OH. A detailed mechanism of nucleation and anisotropic growth kinetics of nanotubes have…
A series of Na1-xKxNdW2O8 (0.0 ≤ x ≤ 0.7) nanoparticles have been synthesized by an efficient glycothermal technique for the first time. SEM measurements confirmed the particle size ranges from 30-200 nm with ellipsoidal shaped morphology. Combined X-ray and neutron diffraction and Raman spectroscopy techniques were u…
We present here tunable and reconfigurable designs of linear and nonlinear plasmonic and hyperbolic metamaterials. Rich scattering features of multilayered composite nanoparticles are demonstrated, which include complex and exotic scattering signatures combining multiple dipolar Fano resonances and electromagnetic ind…
This paper is aimed to study the suitability of bio-polymers, including poly-lactic acid (PLLA) and Mater-Bi, for the production of hollow components by rotational molding. In order to reduce the brittleness of PLLA, the material was mixed with two different plasticizers, bis-ethyl-hexyl-phthalate (DEHP) and poly-ethy…

A new manganese( ii ) [Mn II (DEMP)(NCS)(H 2 O)] (DEMP = Schiff base derived from salicylaldehyde and 2-diethylaminoethylamine) complex has been synthesized and characterized. The complex absorbs light ranging from 200–850 nm. Thus, the molecule is capable of harvesting the entire range of sunlight falling on earth.
