Pore, dome, hollow-sphere and mesh nanoarrays of cobalt were synthesized by electrodeposition on a self-assembled monolayer polystyrene sphere template. The effects of electrodeposition time and patterned templates on the morphology of cobalt nanoarrays were investigated in detail. Morphology dependent magnetic proper…
A novel hybrid material of cadmium telluride, one of the II–VI group of semiconductors, and hexadecyltrimethylammonium-montmorillonite was prepared by the intercalation of cadmium telluride into hexadecyltrimethylammonium-montmorillonite. The resulting hybrids were characterized by X-ray diffraction, FT-IR, HRTEM, TG-…
Scope of this study is to synthesize a nano-dendrimer and its conjugate with C595 MAb against breast cancer cell, followed by its chelating agent with Gd 3+ . At the end, its use as a dual nanosized probe for detection and treatment was investigated.
Nanocrystalline Ni‐La‐Fe‐O catalysts having the general formula NiLa x Fe 2− x O 4 (0.00 ≤ x ≤ 2.00) were synthesized by the combustion route employing urea as a combustion fuel. The calcination process was affected at 500°C. The structural properties of the obtained catalysts were systematically investigated by X‐ray…
The phosphides REIr(2)P(2) (RE = La-Nd, Sm) and arsenides REIr(2)As(2) (RE = La-Nd) were synthesized by a ceramic route via precursor compounds REIr(2) with phosphorus and arsenic, respectively. Well-shaped single crystals were obtained from lead and bismuth fluxes, respectively. The nine pnictides crystallize with th…
Selective photoconversions of photochromic diarylethene derivatives has been described using diarylethene derivative 1a as a model compound. Upon irradiation with 254 nm light, 1a undergoes photocyclization to yield the ring-closed isomer 1b in the absence of oxygen, or is transformed to the thiolactone derivative 1c…
Single-crystalline mesoporous NaTbF4 nano-rice have been successfully synthesized in large scale by reaction of aqueous Tb3+ with sodium fluoride in the presence of ethylenediaminetetraacetic acid (EDTA) at 110 °C for 12 h, which were confirmed by X-ray powder diffraction, energy dispersive X-ray analysis, transmissio…
A first-principles study of structure property correlation and the origin of ferrimagnetism is presented based on LSDA+U method. In particular, the results for the ground state structure, electronic band structure, density of states, Born effective charges, spontaneous polarization and cationic disorder are discussed.…
An unusual PFO(3)(2-)-templated "inverse Keggin" polyanion, [Mo(12)O(46)(PF)(4)](4-), has been isolated from the degradation reaction of an {Mo(132)}-type Keplerate to [PMo(12)O(40)](3-) by [Cu(MeCN)(4)](PF(6)) in acetonitrile. (31)P-NMR studies suggest a structure-directing role for [Cu(MeCN)(4)](+) in the formation…
Air-stable metallic Co nanoparticles were incorporated into the pores or anchored onto the external surface of an ordered mesporous carbon/SBA-15 composite by simply treating the cobalt precursor-impregnated surfactant-containing SBA-15 via the Reaction under Autogenic Pressure at Elevated Temperature (abbreviated to…
The photochemistry and thermodynamics of two terthiophene (TTh) derivatives bearing benzospiropyran (BSP) moieties, 1-(3,3″-dimethylindoline-6'-nitrobenzospiropyranyl)-2-ethyl 4,4″-didecyloxy-2,2':5',2″-terthiophene-3'-acetate (BSP-2) and 1-(3,3″-dimethylindoline-6'-nitrobenzospiropyranyl)-2-ethyl 4,4″-didecyloxy-2,2'…
We report a study on manufacturing and characterization of a platform material for high‐performance lightweight bipolar plates for fuel cells based on nanocomposites consisting of carbon nanotubes (CNTs) and exfoliated graphite nanoplatelets (xGnPs). The experiments were designed and performed in three steps. In the p…
The crystallization characteristics of glasses based on the SiO2-CaO-Na2O-MgO (SCNM) system containing calcium fluoride (CaF2) have been investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The partial replacement of CaO by CaF2 in the studied glass-ceram…
The growth mechanism of ZnO is investigated by a combination of electron microscopy and in situ small-angle X-ray scattering (SAXS). The particles are prepared by the precipitation of zinc nitrate with urea. Depending on the reaction conditions, ZnO, hydrozincite, or a mixture of both phases is detected in our system.…
This article presents the results of research on developing a multi-layer particle filtering half-mask made from biodegradable nonwovens for protection against harmful aerosols. Currently, these half-masks are made from polypropylene (PP), which is a problem in the context of environment protection. Needle-punched non…
Highly ordered Fe-MCM-41 molecular sieve was successfully synthesized by using n-hexadecyl-trimethyl ammonium bromide (CTAB) as the template and the iron ore tailings (IOTs) as the silicon and iron source. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), diffuse reflectance UV-visible…
