High-Pressure Die Casting (HPDC) is one of the major production processes automotive industry, widely used to manufacture geometrically complex nonferrous castings. The mechanical strength and microstructure HPDC-manufactured products changes with variation in several process control parameters such as injection pressure, molten temperature, 1st 2nd stage plunger velocity, cooling etc. Since th...

Nowadays graphene based composites were developed due to their unique structure and excellent properties. Present study involves the preparation of graphene grafted chitosan and hydroxyapatite (GgCH) composite through solution casting method for biomedical applications. The prepared composite was characterised by FTIR, TGA, DSC XRD and SEM analysis. The formation of GgCH composite was confirmed...

The number partitioning problem has proven to be a challenging problem for both exact and heuristic solution methods. In this paper we present a new modeling and solution approach that consists of re-casting the problem as an unconstrained quadratic binary program that can be solved by efficient metaheuristic methods. Our approach readily accommodates both the common two-subset partition case a...

Silicalite-poly(furfuryl alcohol) [PFA] composite membranes were prepared by solution casting of silicalite-furfuryl alcohol [FA] suspension on a porous polysulfone substrate and subsequent in situ polymerization of FA. X-ray diffraction, nitrogen sorption, thermogravimetric analysis, scanning electron microscopy, and energy-dispersive X-ray spectroscopy were used to characterize silicalite nan...

a novel starch/poly (vinyl alcohol)/nano-titanium dioxide (st/pva/nano-tio2) biodegradable nanocomposite film was prepared by homogeneously dispersed tio2 nanoparticles in different ratios of starch/pva-based materials, via a solution casting method. glycerol was used as plasticizer. the mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...

The paper presents a procedure for reconstructing, on the basis of known measurements of temperature, the heat transfer coefficient and the distribution of temperature in given region of solidifying binary alloy in the casting mould. Solution of the considered inverse problem is found by applying the finite element method for solving the corresponding direct problem and the Artificial Bee Colon...

We report the realization of large-area, communications-wavelength electro-optic modulators made via simple solution-casting onto an arbitrary substrate. The devices employ colloidal quantum dots synthesized in, and processed from, the solution phase. Devices exhibit greater than 30% modulation depth at the 1.55 microm eye-safe wavelengths of interest in free-space optical communications. The d...
