4-aminotoluene is known as a good octane additive, the mixture of maleic acid diethyl ester and Succinate acid diethyl ester has good lubricating characteristics. The process of hydrogenation of maleic acid diethyl ester at atmospheric pressure in aqueous solution of 2-propanol over skeletal nickel and modified skelet…
G-quadruplexes play vital roles in telomere maintenance and other biological systems. An effective G-quadruplexes stabilizer can be a promising medicine for cancer therapy. Here, a Zinc(II) with salen derivatives as ligands (ZSC) has been prepared through two simple steps syntheses. 2,4-Dihydroxybenzaldehyde (1 equiv.…
Pure Tin Oxide (SnO2) and Magnesium (Mg) doped SnO2 thin films have been deposited onto glass substrates by spray pyrolysis technique at the substrate temperature of 450°C. The doping concentration of Mg was varied from 1 to 9 wt% (with 2 wt% step) while all other deposition parameters such as substrate temperature, s…
The need to join metallic to composite parts is unavoidable in many complex structures such as modern aircraft. Joints are commonly a weak point in any structure, and this is exacerbated by the use of dissimilar materials. Advanced manufacturing processes
A low-loss arrayed waveguide grating operating at 2.0-µm wavelength is demonstrated with an average on-chip loss of 0.5 dB and a crosstalk per channel of −30.2 dB. These are the lowest reported values for a silicon AWG at 2.0-µm wavelength.
The rare earth Dy3+substituted BiFeO3 (BFO) nanoparticles with general formula Bi1−xDyxFeO3 were successfully synthesized by glycine assisted auto-combustion route. X-ray diffraction confirms the phase transformation from rhombohedral lattice symmetry to orthorhombic lattice symmetry for x ≤ 10 mol. %. Lattice constan…
В обзоре приведены современные сведения о диагностике, течении, традиционной и новой стратегии терапии врожденного нефрогенного несахарного диабета (ВННД) у детей и подростков.
Schematic illustration for the detection of ambroxol based on FRET between the AuNPs and DCF.
In this article, we study a coupled Allen-Cahn-Navier-Stokes model with delays in a two-dimensional domain. The model consists of the Navier-Stokes equations for the velocity, coupled with an Allen-Cahn model for the order (phase) parameter. We prove the existence and uniqueness of the weak and strong solution when th…
In this paper, we propose a textile metamaterial absorber that using screen printing technology. A unit cell of the proposed absorber is motivated from the commercial Chanel logo for wearable applications. The complex impedance of the designed unit cell is analyzed by full-wave simulation. To verify its performance, t…
Bile acid derived cadmium and zinc precursors were utilized for an efficient and single step synthesis of Cd 1−x Zn x Se 1−y S y NCs. Different capping ligand induced carrier relaxation dynamics of the NCs using time resolved spectroscopy was also studied.
The magnetic iron oxide (Fe 2 O 3 ) nanorods were synthesized, and the epoxy resin (EP) composites with the content of 1wt% Fe 2 O 3 were prepared in the condition of magnetic field. X ray diffraction, scanning electron microscopy and comprehensive physical properties measurement system were used to characterize the c…
The achievement of In-Vessel Retention (IVR) against Anticipated Transient without Scram (ATWS) is an effective and rational approach in enhancing the safety characteristics of sodium-cooled fast reactors. Based on the Probabilistic Risk Assessment (Level 1 PRA) for a prototype fast-breeder reactor, Unprotected Loss o…
In the present study, an electro-spark deposition method was applied to obtain a corrosion resistant FeAl-based layer onto the steel surface. In this context, firstly the pulse parameters of deposition process were optimized and among all the parameters, 200 A and 50 s were determined as the best ones. Then, micro-arc…
Self-organized TiO 2 nanotube arrays (TNTs) were fabricated by anodizing the Ti foil using a square wave pulse in a HF + H 2 SO 4 solution. The influence of pulse potential and duration on the morphologies and the electronic properties of the TNTs were systematically investigated by SEM, Raman spectra, XRD, EIS and Mo…
)(thiazole)] (1-trans-PtTz-DNA). However, the molecular basis of recognition between the trans-PtTz-DNA and HMGB1 remains unclear. In the present work, we described a hydrogen/deuterium exchange mass spectrometry (HDX-MS) method in combination with docking simulation to decipher the interactions of platinated DNA with…
In this paper the numerical simulations of microcellular injection molding process for polymer composite with glass fiber for variable content of pores were carried out. In order to evaluate the strength of the three-phase composite structure (polypropylene PP as a matrix, 20% wt. of glass fiber GF and 1-9 % vol. of t…
Oil palm shell (OPS) are non-hazardous waste materials and can be used as alternative coarse aggregates to substitute depleting conventional raw materials. A study on preparing the OPS species (dura and tenera) lightweight concrete (LWC) using with and without heat-treated OPS aggregate has been investigated. Two diff…
Gallium nitride (GaN) crystals were synthesized through the reaction of Ga with LiNH2 at temperature ranging from 450 to 800°C under NH3 atmosphere. Hexagonal GaN crystals with a diameter of approximately 100 µm were obtained. A mechanism that can increase the crystal size during the synthesis of GaN crystals has been…
Field-assisted dissolution theory was the generally accepted mechanism for pore formation and development in porous anodic aluminum oxide (AAO).
