nanocatalysts were used to catalyze the silylcyanation reaction at room temperature, which exhibited excellent catalytic activity with outstanding recyclability.
Herringbone carbon nanofibers (HCNFs) are prepared for use as anode materials in lithium-ion batteries (LIBs).
We investigated effect of retained β phase on mechanical properties of cast Ti-6Al-4V alloy, after solution treatment and subsequent aging for a short time. The alloy was solution-treated at 1123, 1223 K in the α + β phase region and 1323 K in the β phase region for 1800 s, followed by water quenching. After that, as-…
In the past few years, numerous researches have focused on the self-assembly of amyloid peptides and proteins. Especially, the self-assembly of peptides and proteins at interfaces has attracted much attention, on account of the potential applications as well as understanding mechanism of some neurodegenerative disease…
Simvastatin (SV) is a cholesterol-lowering drug of choice classified into a class II of drugs based on bbiopharmaceutical cclassification ssystem (BCS), which is a drug that has a poor solubility but high permeability. Low solubility drug caused a low bioavailability in the blood before it reached its workplace. Cocry…
a gas-phase thermochemical method; the approach is versatile, readily scalable, and avoids the introduction of additional defects by exploiting existing sites. Direct TEM imaging confirmed covalent modification of single layer graphene, without damaging the connectivity of the lattice, as supported by Raman spectromet…
The coordination states of the multivalent neodymium complexes in potassium bis(trifluoromethyl-sulfonyl) amide; K[TFSA] were investigated by Raman spectroscopy. The concentration dependences of deconvoluted Raman spectra were investigated for 0.23–0.45 mol kg −1 Nd(III), and mixed sample of Nd(II)/Nd(III) = 1/3 at th…
The hysteresis Fe-Cr-Co alloys based on the combination of producibility and mechanical and physical properties, are promising magnetic-hard materials. The powder metallurgy provides great technological advantages for designing parts from Fe-Cr-Co system. The higher hysteresis properties were obtained due to the requi…
and iron oxide nanoparticles are promising new fluorescence, magnetic and magnetofluorescence imaging agents. Recently, we have reported their in vitro and in vivo level toxicity profiles which show the non-toxic nature of these polymer capsules encapsulating nanoparticles. However, prior to clinical use, it is essent…
Magnetic nanometer-size catalysts were found to be suitable for a number of bond formations, such as C–C, C–O and C–S cross coupling, Mannich type, carbonylation, alkylation, reduction and asymmetric synthesis. The magnetic nanoparticles can play important roles in homogeneous and heterogeneous catalysis. Recycling ex…
Four donor–donor–acceptor–donor–donor type small molecules were synthesized (by direct alkylation) for photovoltaic applications.
Ground support schemes consist of surface support systems that contact the excavation boundary and a reinforcement system embedded into the rock mass. Under static conditions, these systems can work relatively independently, as the requirement for them to work together is minimal, as demonstrated by practices such as…
We report a systematic study of the role of film thickness on the formation of magnetic domains in Gd-Fe thin films. The films having thickness up to 33 nm show no visible domain contrast, whereas the evolution of magnetic domain starts at a thickness of 50 nm. For 100 nm thick films, meandering stripe domains with lo…
Fabrication of self-forming nanojunction devices is demonstrated using positioning of nanofloret-like building blocks that bridge the gap between two large micron scale electrodes.
The method of evaluation of the weight effectiveness of lattice composite structures using the criteria «load-carrying factor» and «load-carrying factor coefficient» was developed. The results of comparative evaluation of the weight effectiveness lattice composite structure of the lifting fuselage compartment of a hyp…
We report the results of neutron diffraction, ac and dc magnetization, heat-capacity, complex dielectric permittivity and pyrocurrent measurements on an oxide, Li 3 NiRuO 5 , hitherto not paid much attention in the literature.
Metallic soap prepared by saponification of melon seed oil (Cucumeropsis mannii N) with copper (II) salt was investigated as corrosion inhibitor for mild steel corrosion in 1 M hydrochloric acid solution. Results reveal that the metallic soap inhibited the corrosion process by spontaneous physical adsorption of the ph…
Zinc oxide films and aluminum doped zinc oxide films were prepared by specially designed apparatus for ultrasonic spray pyrolysis. Atomization of precursor solution was produced using an ultrasonic transducer at resonant frequency 1.7 ± 0.085 MHz. The resulting films thickness is less than 400 nm, average roughness is…
Fixation is required to reinforce reconstituted collagen for orthopedic bioprostheses such as tendon or ligament replacements. Previous studies have demonstrated that collagen fibers cross-linked by the biocompatible dicatechol nordihydroguaiaretic acid (NDGA) have mechanical strength comparable to native tendons. Thi…
Red-emitting phosphor KAl 1-x PO 4 F:Eu x 3+ (0.1 ≤ x ≤ 1.0) were fabricated by combustion process at temperature 750 °C. The XRD patterns did not indicate presence of the starting constituents and other likely phases which are an indirect evidence for the formation of the desired compound. The photoluminescence study…
