This study report on the synthesis and characterization of molybdenum chlorophyllin (Mo‐Chl) compounds associated in a complex with magnetic nanoparticles (citrate‐coated cobalt ferrite), the latter prepared as a biocompatible magnetic fluid (MF). The complex material was developed for application as a synergic drug f…
Here we present a new class of active system, carbon nanotube-biopolymer composite actuators, which can easily overcome drawbacks of carbon nanotube bulky papers. In such a flexible and biocompatible composite, carbon nanotubes are only served as a highly conductive filler together with an ionic liquid in a chitosan m…
Low-temperature gas adsorption studies have been carried out on six two-dimensional microporous Porphyrin Coordination Lattices (PCL) constructed from (metallo)-porphyrin ligands and dinuclear paddlewheel motif; [RuII,II2(MTCPP)]n, [RuII,III2(MTCPP)X]n and [Rh2(MTCPP)]n (M= H2, Zn; TCPP=4, 4', 4'', 4'''-(porphine-5, 1…
With the development of information, the density and capacity of information storage devices are required to be higher, and the smallest information bit size will be reduced to below the 100 nm accordingly. For the optical data storage and random access memory, the smallest bit size is mainly determined by the optical…
In PEM (Proton Exchange Membrane) Fuel Cell, a two-phase flow, multi-component model has been optimized. The modeling domain consists of the membrane, two catalyst layers, two diffusion layers, and two channels. Both liquid and gas phases are considered in the entire cathode and anode, including the channel, the diffu…
A polymer electrolyte membrane fuel cell (PEM FC) system for automotive applications should meet the rapid variable power demand by consuming the fuel, hydrogen. The fuel delivery system is designed to supply the hydrogen from tank to fuel cell system, and sometime re-circulate exhausted hydrogen to increase the fuel…
In order to find an environmentally benign substitute to hazardous inhibitory agents, the inhibitory effect of γ‐irradiated chitosans against a mixed culture of denitrifying bacteria was experimentally evaluated. Unlike other studies using pure aerobic cultures, the observed effect was not a complete inhibition but a…
We present a X-ray diffraction study of Pr(Ru 1− x Rh x ) 4 P 12 ( x = 0, 0.05), which exhibit a metal-nonmetal transition at about 50–60 K. Superlattice reflections which are related to [Ru,Rh] and P atom displacements could be observed below the transition temperature. In PrRu 4 P 12 , these displacements are found…
The frequency-dependent conductivity of heavy-fermion metals can often be described within the picture of the Drude response: the transport relaxation rate is the only relevant frequency scale and, furthermore, reduced by orders of magnitude compared to normal metals. While the relaxation-time enhancement corresponds…
Film deposition experiments are performed in circular glass capillaries of 500 μm diameter. Two surface wettabilities are considered, contact angle of 30° for water on glass and of 105° when a hydrophobic coating is applied. It was observed that the liquid film deposited as the meniscus translates with a velocity U pr…
Recently titiania nanotubes show their potential in implant application, however their cytocompatibility are still controversial. In previous reports concerning the cytocompatibility of titania nanotube, someone annealed the titania nanotube to transform it from amorphous into anatase type while others didn't. It's be…
Thorium fuel cycle with recycled U‐233 has been widely recognized having some contributions to improve the water‐cooled breeder reactor program which has been shown by a feasible area of breeding and negative void reactivity which confirms that fissile of 233U contributes to better fuel breeding and effective for obta…
In this work, the epitaxial graphene channel formed on 3C-SiC grown on a Si substrate backgate transistor was designed, fabricated and characterized for electronic and optoelectronic applications. Even though a significant amount of the gate leakage current is observed, the experimental results show the device works a…
We demonstrated a simple transfer method enables to fabricate the single-walled carbon nanotube (SWCNT) film on the plastic substrate. SWCNT network was separated from the initial substrate and transferred onto another substrate using the nitric acid. We also found that electrical conductivity of transferred film was…
The impact induced initiation of covered HE is an important problem associated with safety. In this work we investigate the impact shock detonation of high explosives BPX confined in an steel spherical shell by a normal impact at velocity of 2000 m/s by the help of two-dimensional axisymmetric finite element analysis.…
Nowadays, the natural fibres market is having an important growth due to the commitment of contemporary society with the sustainable development that leads the natural resources preservation and the environment protection. Fibres from banana food wastes provide high mechanical properties related to other natural fiber…
Magnetization of a single crystal of cubic PrMg3 with a Γ3 non-Kramers doublet ground state has been examined at low temperatures down to 60 mK in fields up to 8.5 T. The 4f-electronic contribution of the magnetic susceptibility χ4f(T) is significantly enhanced over the expected Van-Vleck behavior and shows like tempe…
Three-dimensional Li ion microbatteries are known for their high surface area which leads to high current and capacity compared to traditional planar batteries. This paper describes economical approaches to prepare half 3D microbatteries based on silicon microchannel plates (MCP). The high aspect ratio silicon MCP is…
Interface-trap effects are analyzed in inversion-type, self-aligned In0.53Ga0.47As and In0.53Ga0.47As/ In0.2Ga0.8As MOSFETs with ALD ZrO2gate dielectric. Interface-trap densities in the order of 1013cm-2eV-1are required to explain the measured subthreshold slopes. For these Ditvalues, donor-like interface traps are co…
In this report the study of direct holographic recording of the surface relief gratings on amorphous chalcogenide thin (0.5-10 m) films is presented in view of the light polarization state. Recording was performed on As2S3 by 532 nm wavelength laser light. Because of direct surface relief formation, its efficiency may…
