The ability of ω-imidazolium functionalized poly(L-lactide) (ImPLLA) chains to improve the CNT dispersion within the PLLA matrix was demonstrated in bulk and at elevated temperatures using melt-processing techniques. This approach brings new supramolecular tools to the formation of CNT-based biomaterials derived from…
Polycrystalline diamond films exhibiting (100) oriented surfaces have been subject to a low pressure hydrogen plasma for durations up to 20 h. The topography of spatially defined 20 × 20 μm areas of the samples were imaged by atomic force microscopy at intervals during the plasma exposure. The mean surface roughness o…
In the presence of H2S, metallic materials, such as carbon and low alloy steels, may suffer hydrogen damage and hydrogen embrittlement. In this paper the influence of hydrogen and low temperature on mechanical properties of two pipeline materials, X65 micro-alloyed and F22 low alloy steels, is studied. An electrochemi…
The steadily growth of Wood Plastic Composite (WPC) in exterior applications resulted a need to understand their durability. In Malaysia, the durability of WPC is not only affected by mold and decay fungi as biodegradation agents but also due the termites attack. Therefore, this study was carried out to investigate th…
Novel composites of highly ordered and stable biphenyl-bridged periodic mesoporous organosilica (PMO) materials confined within the pores of anodic alumina membranes (AAM) were successfully synthesized by evaporation-induced self-assembly (EISA). 4,4′-Bis(triethoxysilyl)biphenyl (BTEBP) was used as a precursor in comb…
The light-controlled fluorescence molecular switch was prepared with Au nanoclusters and thiolated spiropyran dyes. Its fluorescence can be reversibly modulated using UV/Visible light due to fluorescence resonance energy transfer (FRET) from the Au NCs to the open-ring state merocyanine of the spiropyran molecules.
In an effort to better understand, direct and control the crystallization of molecular and macromolecular compounds, an approach using colloidal templates as substrates for heterogeneous nucleation was investigated. These templates combine both tuneable chemical functionalities and geometrical features, altering the c…
Powders of strontium hexaferrite (SrFe12O19 - SrF) have been prepared by the sol-gel process. The prepared precursor was calcined in two different calcination techniques, using conventional furnace and microwave furnace. Thermal analysis studies showed exothermic and endothermic reaction peak at room temperature to 12…
In cooling-type batch crystallization, the influence of undersaturation operation on crystal size distribution (CSD) was investigated by computational simulation. The model used considered the primary and secondary nucleation rates, size-dependent growth rate, and size-dependent dissolution rate limited by mass transf…
The solid oxide fuel cell (SOFC) can operate effectively on a variety of fuels, such as coal-syngas and hydrogen. A Ni-based cermet is a cost-effective anode material for these fuels; however, H 2 S in the fuel can degrade cell performance by poisoning the Ni-based anode. In this research, nickel- gadolinium doped cer…
The appearance of high-mobility electrons at the LaAlO 3 /SrTiO 3 interface has raised strong interest in the material science community and a lively debate on the origin of the phenomenon. A possible explanation is an electronic reconstruction, realizing a transfer of electrons to SrTiO 3 at the interface, thereby av…
Biodegradability and COD release of polylactic acid (PLA), polycaprolactone (PCL) and polylactic acid/Poly (3- hydroxybutyrate-co-3-hydroxyvalerate) blend (PLA/PHBV) were determined in water solution with sludge as the inoculum, and the feasibility of using them as carbon sources to remove nitrate from nitrate-contami…
Cyclotriphosphazene derivatives containing a P-NHR group in the side-chain react in the presence of a strong base to form stable intermolecular bridged products. Reaction of sodium hydride with mono-spiro cyclophosphazene derivatives having a P-NH group, N(3)P(3)Cl(4)[O(CH(2))(3)NH], (1a) or N(3)P(3)Cl(4)[CH(3)N(CH(2)…
Mechanism of cathodic electrodeposition of CuSCN from ethanolic solutions containing Cu2+ and SCN- was studied in detail. Job's plot for the absorption spectra of mixed solution in various Cu2+: SCN- ratios have revealed the presence of [Cu(SCN)2]0 as a soluble species responsible to the electrode process in SCN- rich…
An adhesive polymer-dispersed liquid crystal (PDLC) film with low cohesive strength is formed by the solvent- and polymerization-induced phase separation of PlatSil Gel-10 and nematic liquid crystal 4-n-pentyl-4′-cyanobiphenyl (5CB). We find that the director configuration of the dispersed 5CB droplets is sensitive to…
Single-crystalline In(OH)3 nanocubes were synthesized in a simple aqueous solution, without using a surfactant, at a temperature as low as 90 °C. To elucidate the growth mechanism, the structural evolution of In(OH)3 nanocubes during the synthesis process were carefully examined. The experimental results showed that t…
We report on the fabrication of a novel material with the ability to remain in solution even under the very demanding conditions required for structural and dynamic characterization of biomacromolecule assays. This stability is provided by the increase in surface area of a low density material (aluminium) natively coa…
Nanocomposite K-Co-CeO(2) catalysts were synthesized by the controllable micropore-diffused co-reaction method. Due to the size-match nanometre effect between CeO(2) support and active components and formation of NO(2), these cheap nanocomposite catalysts exhibit super catalytic performances which are as good as a sup…
A simple and generic method is developed to form organic nanoparticles in porous materials by solvent evaporation. The composites can be readily dissolved in water to produce aqueous organic nanoparticle dispersions.
Amorphous thin films of titanium oxide (TiOx) have been deposited on K9 glass substrates by dc reactive magnetron sputtering from a pure titanium target at different oxygen partial pressure. The structure and composition of these films have been characterized by x-ray diffraction (XRD), and x-ray photoelectron spectro…
