Abstract Effect of running‐in process on friction behaviour of carbon nitride (CNx) coating in N 2 gas stream was investigated with a newly introduced two‐step ball‐on‐disk friction test, where the rubbed Si 3 N 4 ball in the pre‐sliding (step 1) was replaced by a new CNx‐coated Si 3 N 4 ball in the subsequent sliding…
Cu–Cu2O–CuO/activated carbon heterostructure composites with visible-light activity have been successfully synthesized by a simple carbothermal reduction procedure using CuSO4 as a single precursor. The resultant samples were characterized by X-ray diffraction, transmission electron microscopy, and X-ray photoelectron…
The nanotechnology offers some exciting possibilities in cancer treatment, including the possibility of destroying tumors with minimal damage to healthy tissue and organs by targeted drug delivery systems. Considerable achievements in investigations aimed at the use of ZnO nanoparticles and nanocontainers in diagnosti…
Radiation shielding is an obstacle in long duration space exploration. Boron Nitride Nanotubes (BNNTs) have attracted attention as an additive to radiation shielding material due to B<sup>10</sup>’s large neutron capture cross section. The B<sup>10</sup> has an effective neutron capture cross section suitable for low…
This paper studies the silicone based materials used for light emitting diode (LED) packaging. A phenyl vinyl silicone resin (PVS) with high refractive index was synthesized in this paper. Four types of packaging materials were prepared by a hydrosilylation reaction between PVS and hydride silicone materials. This stu…
The area of silica nanoparticles is incredibly polygonal. Silica particles have aroused exceptional deliberation in bio-analysis due to great progress in particular arenas, for instance, biocompatibility, unique properties of modifiable pore size and organization, huge facade areas and pore volumes, manageable morphol…
The redox behavior of 5 nm Fe-Me alloyed nanoparticles (where Me = Pt, Au, and Rh) was investigated in situ under H 2 and O 2 atmospheres by near ambient pressure X-ray photoelectron and absorption spectroscopies (NAP-XPS, XAS), together with ex situ transmission electron microscopy (TEM) and XAS spectra simulations.…
The synthesis of monodisperse magnetic ferrite nanomaterials plays an important role in several scientific and technological areas. In this work, dibasic spinel MFe2O4 (M=Mg, Ni, Co, Fe, Mn) and polybasic spinel ferrite MCoFeO4 (M=Mg, Ni, Mn, MgNi) nanocrystals were prepared by the calcination of layered double hydrox…
By reaction of [As2W19O67(H2O)](14-), NiCl2·6H2O, and phen under hydrothermal conditions, a new organic-inorganic tungstoarsenate hybrid [Ni(phen)3]4[As2W18O60]{[Ni(phen)2][H2As2W18O60]}·12H2O (where phen = 1,10-phenanthroline) (1) was obtained via self-assembly and characterized by elemental analysis, infrared (IR) s…
Guided mode resonance (GMR) enhanced second- and third-harmonic generation (SHG and THG) is demonstrated in an azo-polymer resonant waveguide grating (RWG), comprised of a poled azo-polymer layer on top of a textured SU8 substrate with a thin intervening layer of TiO2. Strong SHG and THG outputs are observed by matchi…
Na2SO4, Na2SO4: Li, Na2SO4: Li, Eu, Na2SO4: Li, Dy and Na2SO4: Li, Eu, Dy phosphors were prepared using a slow evaporation technique followed by their subsequent calcination at 400 °C for 4 h. Doping with a Li+ ion stabilized the thenardite phase of the host matrix, while codoping with rare earth stabilized the phase…
800x600 Durability of materials to flame and stability at high temperatures are very important in order to increase the field of use. Non-flammability is not the only requirement materials should not have toxic gas products during the burning, also. Anhydrous zinc borate was chosen as flame retardant due to its advant…
Abstract A method was developed for the direct functionalization of metalloporphyrins at the methine protons (meso positions) to yield asymmetric alkynylated derivatives by using gold catalysis and hypervalent iodine reagents. This single‐step procedure was applied to b ‐type heme and the product was incorporated into…
Corrosion behavior of Ti-6Al-4V alloy has been investigated in acid rainwater (ARW) at different pH values using various electrochemical techniques and scanning electron microscope examination. This work is important environmentally and industrially. The results obtained from polarization measurements showed that corr…
Cd1-xCoxS nanofilms (0 ≤ x ≤ 0.08) deposited by chemical bath deposition have been studied using energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, and ultraviolet-visible-near-infrared spectroscopy. A redshift in Cd-S stretch with Co doping has been observed.…
The glass-fiber-reinforced aluminum laminates were obtained by anodizing aluminum alloy under anodizing voltage of 10, 20, and 30 V in the 200 g/L H3PO4 electrolyte. Scanning electron microscopy (SEM), short beam, and tensile tests were employed to determine the surface morphology, interlaminar shear strength (ILSS) a…
The local structure of an amorphous tellurium (a-Te) film was investigated by extended X-ray absorption fine-structure analysis. The covalent bond length shortens and the Debye-Waller factor of the intra-chain decreases in a-Te compared with trigonal Te (t-Te). The value of the intra-chain coordination number is close…
Abstract We synthesized a long‐chain phenylazopyridine ligand and used it to obtain three new amphiphilic trinuclear ruthenium acetate clusters. The amphiphilicity and anisometric form of the long‐chain ligand allowed the complexes to self‐assemble at the liquid–air interface and enabled their deposition by the Langmu…
Oleic acid modified iron oxide nanoparticles (IONs) with different sizes were synthesized and mixed with styrene-butadiene-styrene block copolymer (SBS) with a lamellar structure. The octadecene segments on the oleic acid molecules have chemical affinity with the polybutadiene (PB) blocks, which makes IONs tend to be…
Through a combination of an electronic-type selective diazonium-based attachment of a Hamilton receptor unit onto the carbon nanotube framework and a supramolecular recognition approach of a cyanuric acid derivative, we herein introduce a highly promising strategy for the tuning of carbon nanotube solubility and, dire…
