The release of untreated dyes into water bodies leads to serious environmental complications because of high toxicity and high Chemical Oxygen Demand (COD). There are many techniques available to degrade dye color out of which the adsorption method, owing to its economic feasibility and simplicity in design makes it m…
Small-angle neutron scattering (SANS) has been utilized for micro-structural investigation on laboratory heats of oxide dispersion strengthened (ODS) 13.5 Cr wt % ferritic steel, with 0.3 wt% Y2O3 and with variable Ti and W contents. The results show that increasing the Ti content from 0.2 to 0.4 wt% a distribution of…
There are four commonly practiced processes for the production of impact-modified styrenics. These processes are bulk, bulk suspension, emulsion, and blending. During the polymerization, grafting occurs on the rubber backbone by either hydrogen abstraction of an allylic hydrogen or addition to a double bond. Emulsion…
This note considers Sturm oscillation theory for regular matrix Sturm-Liouville operators on finite intervals and for matrix Jacobi operators. The number of space oscillations of the eigenvalues of the matrix Prufer phases at a given energy, defined by a suitable lift in the Jacobi case, is shown to be equal to the nu…
Today, the development of building materials based on toxic or non-toxic industrial waste is a topical issue for the productive structures in industrialized countries. In this article, non-toxic wood waste (wood chips) is used to improve the characteristics of ordinary concrete (lightness, thermal insulation, acoustic…
The development of integrated vertical III-V nanowire (NW) stimulated emitters in silicon photonics while achieving an efficient light coupling through vertical III-V NW lasers into horizontal optical silicon waveguides is demanding. This is mainly due to the directionality and contradiction of the simultaneously sati…
The present study involves the fabrication of CH and CH-Ag hydrogel beads and the investigation of the antimicrobial properties. The beads were fabricated using a simple coacervation method. The successfully synthesized beads were characterized by UV-Vis and FTIR. The surface morphology, shape and diameter of the samp…
Two series of benzoxazines were synthesized from o-, m-, and p-methoxyphenols, two polyetheramines with different molecular weights, and formaldehyde. The glass transition temperatures (Tgs) of m-methoxyphenol-based polybenzoxazines are respectively higher than those of o- and p-methoxyphenol-based counterparts. The p…
The present article reports the growth mechanism of zinc oxide (ZnO) nanowires grown on silicon substrate pre-coated with ZnO buffer layer by thermal evaporation method. ZnO nanowires are grown for different growth time of 0, 30, 90 and 120 mins with controlled supply of Ar and O2 gas at 650 °C. The structural, morpho…
A single layer of BiFeO3 (BFO)/epoxy resin composite with thickness of 3 mm was fabricated by polymerized 70 wt% of sintered BFO as fillers and 30 wt% of epoxy resin polymer as matrix. The electromagnetic and the microwave absorption properties of BFO/epoxy resin composite were reported. The reflection loss (RL) of th…
The activated carbon produced from oil palm empty fruit bunches (ACEFB) shows good properties to act as a dispersing agent in the synthesis of BCZY ceramic material. However, the untreated ACEFB (u-ACEFB) shows some impurities still present after calcination. Thus, it has to be functionalized (f-ACEFB) by using chemic…
Abstract The physical and chemical properties of typical nitrate energetic materials under hydrostatic compression and uniaxial compression were studied using the ReaxFF/lg force field combined with the molecular dynamics simulation method. Under hydrostatic compression, the P–V curve and the bulk modulus (B0) obtaine…
Caesium propanoate monohydrate, Cs+·C3H5O2−·H2O, is composed of two symmetry-independent Cs+cations, which are situated on the special position 4eof space groupP\overline421m, one symmetry-independent propanoate molecule in a general position and a pair of water molecules also situated on special position 4e. Two pair…
A new morphogenetic strategy was developed to realize continuously modulated and reprogrammable three-dimensional shape transitions by fully exploring the potential of macromolecular conformational modulations. Geometric information was defined in the planar shape memory polymeric sheets through the application of spa…
Abstract An analytical model is proposed to evaluate the nodal force induced by a segment of dislocation upon an arbitrary shaped triangular element. This calculation is required in hybrid methods that associate dislocation dynamics to boundary or finite element to solve simultaneously the evolution of large ensembles…
Job's tears (Coix lacryma-jobi) stalk was used as a possible raw material for particleboard. A urea-formaldehyde (UF) resin was synthesised in the laboratory with resin solids at 50% content as a particleboard binder. The physical characteristics of the synthesised UF resin were analysed for solids content, specific g…
Four dendrimeric hexa- or nona-dentate Schiff base ligands based on triazine structure and several lithium and vanadium(IV) complexes with these ligands were synthesized and characterized by elemental analysis, 1H NMR and IR spectra. The synthetic methods are described, and we paid special attention to the need to use…
The effect of Cr and Ni substitution on electrochemical performance of layered LiCo0.9M0.1O2 (M=Cr and Ni) has been investigated. Partial substituted of LiCo0.9Cr0.1O2 and LiCo0.9Ni0.1O2 has been synthesized using a self-propagating combustion (SPC) method with annealing temperature of 700 ̊ C for 24 h. The starting m…
The aggregation behaviors of Basic Red 46 in water, water/dimethylacetamide (water/DMAc), and water/DMAc/NaCl were investigated by both a Transmission Electron Microscope and a laser particle size analyzer. The corresponding electric conductivity of the dyeing solution and surface zeta potential of dye aggregates usin…
Particleboard was produced by mixing oil heat-treated rubberwood particles at different ratios, with the goal of achieving high dimensional stability. Rubberwood particles were soaked in palm oil for 2 h and heat treated at 200 °C for 2 h. The treated particles were soaked in boiling water for 30 min to remove oil and…
