The paper addresses the effect of gold nanoparticle (Au-NP) deposition on the thermoresponsive volume phase transition of the weak polyelectrolyte poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) brushes. PDMAEMA brushes were synthesized via surface-initiated atom transfer radical polymerization (SI-ATRP). The PDMA…
We investigated the electronic transport properties of epitaxial SnO2−x thin films on r-plane sapphire substrates. The films were grown by pulsed laser deposition technique and its epitaxial growth direction was [101] and the in-plane alignment was of SnO2−x [010]//Al2O3[12̄10]. When the SnO2−x films were grown in the…
Plasmonic Ag core-satellite nanostructures were synthesized by utilizing the ultrathin silica shell as a spacer to generate a tunable nanogap between the Ag core and satellites. To synthesize the nanoparticles, Ag nanoparticles (Ag NPs) with a diameter of ∼60 nm were synthesized as cores, on which Raman dyes were adso…
[EN] Nd3+-doped RE3Ga5O12 (RE = Gd, Y, and Lu) nano-crystalline \ngarnets of 40-45 nm in size have been synthesized by a sol-gel method. \nWith the decrease of the RE atom size, the chemical pressure related to the \ndecreasing volumes of the GaO4 tetrahedral, GaO6 octahedral and REO8 \ndodecahedral un…
Beam steering devices have gained extensive interests in the fields of optical interconnects, communications, displays and data storages. However, the challenge lies in obtaining an ultrafast beam steering structure in the optical regime. Here, we propose phase-array-like plasmonic resonators based on metal/phase-chan…
AIM: We tried to develop a multimodal iron oxide nanoparticles (IO NP) imaging probe by an encapsulation method using specific amphiphiles for (68)Ga-labeling and lymph node-targeting. MATERIALS & METHODS: Nanoparticles (NPs) were encapsulated with a solution containing polysorbate 60 and the amphiphiles. The prepared…
The treatment of volatile organic compounds (VOC) emissions is a necessity of today. The catalytic treatment has already proven to be environmentally and economically sound technology for the total oxidation of the VOCs. However, in certain cases, it may also become economical to utilize these emissions in some profit…
A fluidized bed coupled rotary reactor has been designed for coating on nanoparticles (NPs) via atomic layer deposition. It consists of five major parts: reaction chamber, dosing and fluidizing section, pumping section, rotary manipulator components, as well as a double-layer cartridge for the storage of particles. In…
To study the effect of pollution level on electric field distribution of polymeric insulators, simulations were carried out using Comsol Multiphysics. The effect of light, medium, heavy and very heavy pollution on the electric field and potential distribution was investigated. Pollution was modelled as a uniform condu…
Analytical results for a voltage induced 180 perpendicular magnetization switching in a single magnetic nanoelement are presented. This 180 switching is achieved by combining perpendicular magnetic anisotropy due to surface effects with a temporally short voltage induced strain pulse. The angular momentum of the magne…
Ionic liquids ( ILs) attracted great attention as green corrosion inhibitors for steel in aggressive environments. The present work synthesize new IL using chitosan through amidation and quaternization reaction with oleic acid and p-toluene sulfonic acid, respectively. The chemical structure of the prepared polymeric…
Despite our extensive knowledge of the structure of negatively charged cell surface proteoglycans and sialoglycoconjugates in the brain, we have little understanding of how their negative charge contributes to brain function. We have previously shown that intensely photoluminescent 9-nm diameter quantum dots (QDs) wit…
In this work, we highlighted the effect of surface modifications of one-dimensional (1D) ZnO nanostructures (NSs) grown by the vapor-solid mechanism on their antibacterial activity. Two sets of ZnO NSs were modified separately - one set was modified by annealing in an Ar environment, and the second set was modified in…
Compounds that can gelate aqueous solutions offer an intriguing toolbox to create functional hydrogel materials for biomedical applications. Amphiphilic Janus dendrimers with low molecular weights can readily form self-assembled fibers at very low mass proportion (0.2 wt %) to create supramolecular hydrogels (G'≫G'')…
Samples of sodium aluminum iron phosphate glasses of the composition (mol %) 40 Na 2 O, (20 − x ) Al 2 O 3 , x Fe 2 O 3 , 40 P 2 O 5 (series I) and 35 Na 2 O, (20 − x ) Al 2 O 3 , x Fe 2 O 3 , 45 P 2 O 5 (series II) were synthesized. The phase composition and structure of the samples obtained were determined by X-ray…
Methods of synthesis and formation of a high-dense ceramic prepared from barium cerate and zirconate, which is applied as electrolyte in solid oxide fuel cells, are considered in the present work. The main attention is devoted to the relatively new strategy of solid-state reactive sintering method, which consists in t…
This Account describes a new electrochemical synthetic strategy for direct growth of crystalline covalent group IV and III-V semiconductor materials at or near ambient temperature conditions. This strategy, which we call "electrochemical liquid-liquid-solid" (ec-LLS) crystal growth, marries the semiconductor solvation…
We present synthesis and characterization of a new magnetic atomic laminate: (Mo0.5Mn0.5)2GaC. High quality crystalline films were synthesized on MgO(111) substrates at a temperature of ∼530 °C. The films display a magnetic response, evaluated by vibrating sample magnetometry, in a temperature range 3-300 K and in a f…
The accurate prediction of solubility of drug-like molecules is difficult, and perhaps a satisfactory general model is not yet available. The most cited challenge to good prediction has been the lack of enough high-quality and drug-relevant solubility data that adequately cover the chemical space of drugs. This review…
The modern transmission and distribution network relies on SF6technology because of its remarkable arc quenching properties and dielectric insulation (approximately 3 times greater than air). However, even if SF6Switchgears are safe for the environment, the SF6insulating gas has potential significant environmental imp…
