Palladium nanoparticles were dispersed on the surface of poly (diallyl dimethyl ammonium chloride) - mesoporous carbon (Pd/PDDA-MC) composite as a catalytic for the environmental hormones nonylphenol (NOP) electrochemical oxidation. The Pd/PDDA-MC was characterized by transmission electron microscope (TEM), scanning e…
Oil Palm Empty Fruit Bunch (OPEFB) was pretreated using Deep Eutectic Solvent (DES) at different parameters to enable a highest yield of sugar. DES is a combination of two or more cheap and safe components to form a eutectic mixture through hydrogen bond interaction, which has a melting point lower than that of each c…
In this research the interaction between oxygen molecules and the outside and inside surfaces of pristine and Ge-doped (4,4) armchair and (6,0) zigzag models of aluminum phosphide nanotubes (AlPNTs) was systematically investigated using density function theory. Structural parameters, adsorption energy, quantum paramet…
Thermally reduced graphene oxide transforms regular paper from hydrophilic to hydrophobic.
Results of testing methodology for calculating two-phase flows based on the method of fluid in the cells (VOF method), and the procedure for CSF accounting of surface tension forces in the microchannel are considered in the work. Mathematical modeling of two-component flow fluid -fluid in the T- microchannel conducted…
Subject of this work is the development of a simple and cost-efficient process for conditioning the surface of forming tools for deep drawing processes in order to minimize friction and wear to a level that dry forming processes without any lubricants will be possible in future. The approach chosen is an oxidative hea…
Palygorskite/polyacrylamide (PAM) composited thickeners were prepared via in-situ polymerization. To optimize the preparation, the dependence of the viscosity, rheological properties and electrolyte resistance of the composited thickeners on the initiator concentrations, sodium hydroxide concentrations and palygorskit…
We develop a quantitative model to calculate the optimal experimental conditions for the etching of the oxide barrier of porous anodic alumina (PAA) membranes. The method is applied to a membrane fabricated at 370 V in a solution of 2% citric acid. The process creates a network of small pores at the bottom of the larg…
For an analysis of the oxidation behavior of UO2 nuclear fuel pellet under a loss of water coolant accident in a spent nuclear fuel pool of an LWR, thermodynamic assessments of UO2 oxidation were carried out under various atmospheric conditions. In a steam atmosphere, it was assessed that UO2 would not be fully oxidiz…
The crystal structure and magnetic properties of the compound Na5[Mn(l-tart)2]·12H2O (1, l-tart = l-tartrate) have been investigated over the pressure range 0.34-3.49 GPa. The bulk modulus of 1 has been determined as 23.9(6) GPa, with a compression of the coordination spheres around the Na(+) ions observed. 1 is there…
In this paper an effort has been made to study the effects of ageing variables on the abrasive wear behavior of Aluminium 6061 alloy and Silicon Carbide particulate reinforced Aluminum 6061 Composites. The composite material was prepared by using stir casting technique. The as-cast material was heat treated by a metho…
A chemical bond includes both covalent and ionic characteristics. We develop an experimental method to estimate the degree of each contribution based on magnetic susceptibility measurements, in which Pascal's scheme for Larmor diamagnetism is combined with electronegativity. The applicability to metal hydrides is also…
The spectral characteristics of a set of square planar arrays of spherical ferroelectric barium titanate particles embedded in extruded polysterene foam have been investigated. Considerable differences are observed between the measured transmission and reflection coefficients and the corresponding calculated values fo…
The application of polymer matrix composites has found valuable in many engineering fields like electrical, marine, aerospace, electronics and microelectronics. Thus, a new technique like microwave through electromagnetic energy was explored for processing of polymer matrix composite. The roles of microwave in the pos…
Influence of nano-particles sizes on photovoltaic characteristics.
In this work, anodically grown ZrO2 nanotubes (NTs) are examined for the first time for use in micro solid oxide fuel cell (μ-SOFC) applications. This is due to their high surface area to volume ratio and useful nanoscale morphological features (e.g., 5-100 nm thick NT bases that could serve as the electrolyte layer).…
A novel catalyst of supported Ni 4 La oxide calcined at 400 °C in nitrogen completely decomposes N 2 O at 375 °C.
The complexation behaviour of bis(methyl)(thia/selena)salen ligands towards Ag(I) ions in the presence of PF6−, ClO4− and NO3− ions, and the self-assembling of the resultant complexes were explored. Changes in counter anion and coordinating sites (S/Se) led to a structural diversity of complexes as determined using si…
Effects of wiping copper-alloyed stainless steel surfaces with disinfectants to remove protein surface contaminants and re-establish their antibacterial activities were quantitatively studied. Disinfectants used were sodium hypochlorite aqueous solutions and ethyl alcohol aqueous solutions. Wiping with NaOCl aqueous s…
We report an original approach exploiting the photoelectrochemical properties of quantum rods and the versatility of Au(I) organometallic chemistry to control DNA surface grafting. This one-pot aqueous approach provides Janus biofunctionalized nanoparticles, the assembly of which should results in the emergence of syn…
