Flax straw and flax fibers are renewable resource and have potential for use in the manufacturing industry. In this study, flax fiber (including 58% flax shives by weight) was studied as a material to be added into polyethylene (high density polyethylene and linear low density polyethylene) in 10% by mass and processe…
3D hollow VO2(B) micro-spheres have been fabricated by using the hydrothermal method. The obtained VO2(B) hollow spheres were built up from well-defined VO2(B) nanothorn single-crystals, of which were perpendicularly parked on the sphere surface. When this hollow spheres was used as the cathode material for a lithium-…
Here we present a systematic study on the morphological deviation of ZnO nanostructure (from sheets to micro-flowers) by varying pH of the solution via precipitation method. In this regard, zinc nitrate hexa-hydrate, NaOH and hydroxylamine hydrochloride (NH2OH·HCl) were used. The solution of all three compounds was re…
A novel quantum-dot-based solar cell assembly consisting of core-shell Zn-doped CuInS2@ZnS (Zn-CIS@ZnS) quantum dots associated with short ZnO (5 μm in length) nanowires was developed and systematically investigated in terms of its nanostructure and optical properties, associated with corresponding solar cell paramete…
The initial formation of initiating sites for atom transfer radical polymerization (ATRP) on various polymer surfaces and numerous inorganic and metallic surfaces is elaborated. The subsequent ATRP grafting of a multitude of monomers from such surfaces to generate thin covalently linked polymer coatings is discussed b…
We report the synthesis of a series of hydrophilic butadiyne-linked conjugated zinc porphyrin dimers, designed as photodynamic therapy (PDT) agents. These porphyrin dimers exhibit exceptionally high two-photon absorption cross sections (delta(max) approximately 8,000-17,000 GM) and red-shifted linear absorption spectr…
The effect of coating with irradiated Crab and Shrimp chitosan (CHIirr, Mv = 5.14 × 104) and un-irradiated Crab chitosan (CHIun, Mv = 2.61 × 105) on postharvest preservation of mango (Mangifera indica L.) fruit was studied. Irradiation at 100 kGy and 200 kGy of both Crab chitosan and Shrimp chitosan were used and the…
In this work, we report a low-cost facile method for the production of few-layer graphene sheets in large quantities through radio-frequency chemical vapor deposition.
Aluminium hydride has been synthesized electrochemically, providing a synthetic route which closes a reversible cycle for regeneration of the material and bypasses expensive thermodynamic costs which have precluded AlH(3) from being considered as a H(2) storage material.
In a view to reduce the cost of production and the harmful destruction of our environment, so many research work has been conducted and still ongoing as to the possibility of using natural fibres that are wholly degradable in combination with biodegradable thermoplastic materials. This has shown significant result so…
Cobalt hydroxide nanoflakes with a maximum specific capacitance of 735 F/g are successfully synthesized by a facile chemical precipitation method. To enhance energy density, an asymmetric-type pseudo/electric double-layer capacitor is considered where Co ( OH ) 2 nanoflakes and activated carbon act as the positive and…
The numerical approximations to the Allen–Cahn type diffuse interface models are studied, with a particular focus on their performance in the sharp interface limit and the effectiveness of high order discretization schemes. Different spatial discretizations of an energy functional in the diffuse interface framework ar…
Electrospinning utilizes electric forces and hence the electrical properties of the solution have an effect the process. The study examined the effect of conductive additive and filler on the electrospinning process with polyacrylonitrile (PAN). Electrospinning trials were performed using a pure PAN solution, a salt-c…
Herein we report on a systematic investigation of the thermal expansion of select Mn+1AXn phases. The bulk dilatometric thermal expansion coefficient αdil was measured in the 25–1200 °C temperature range and the thermal expansion of more than 15 of these phases was studied by x-ray diffraction in the 25–800 °C tempera…
Phenylenediamine bis(phenolate) binds in the reduced dianionic form to titanium and zirconium alkoxides giving either mononuclear or bridging dinuclear complexes depending on the metal precursors; the fluxional mononuclear titanium complex is found to exhibit extremely high activity in polymerisation of rac-lactide in…
This paper reports a high-yield synthesis of Ag nanospheres made up of primary nanoparticles. The size of the silver nanospheres can be controlled by changing the concentration of poly(vinylpyrrolidone) (PVP) which acts as a stabilizer. In addition, the surface morphology of the nanospheres can be well controlled thro…

A well-established, silver fishnet design has been further miniaturized to function as a negative-index material at the shortest wavelength to date (to our knowledge). By studying the transmittance, reflectance, and corresponding numerical simulations of the sample, we report in this Letter a negative refractive index…
The reversible intercalation of ions into manganese dioxide was first reported in an aqueous system and a large capacity was measured. A cycle life test was performed at , and after , no capacity fading was found, which indicates the good cycling properties of manganese dioxide toward the insertion of zinc ions. X-ray…
The fluorescence resonance energy transfer (FRET) between CdSe-ZnS QDs and fluorophore-labeled galactose or fluorophore-labeled dopamine linked to phenyl boronic acid-functionalized QDs is used to develop competitive assays for the optical detection of galactose, glucose, or dopamine.
