The structural properties of glassy Ge${}_{2}$Se${}_{3}$ were studied in the framework of first-principles molecular dynamics by using the Becke-Lee-Yang-Parr scheme for the treatment of the exchange-correlation functional in density functional theory. Our results for the total neutron structure factor and the total p…
Corrosion protective composite coatings were prepared on AZ31 Mg alloy using plasma electrolytic oxidation (PEO) and cerium conversion (CeC) coating, and their electrochemical corrosion properties were evaluated by potentiodynamic test and electrochemical impedance spectroscopy (EIS). The PEO coating was porous and co…
The effects of kenaf (KNF) loading and 3-aminopropyltriethoxysilane (APTES) on the tensile properties, water uptake, and thermal properties of KNF-filled polypropylene (PP)/waste pulverized tire (WPT) composites were investigated. The composites were prepared using a Thermo Haake Polydrive internal mixer, where KNF lo…
Studies of magnetic properties of a family of tetranuclear M(II)(2)Ln(III)(2) (M = Ni, Zn; Ln = Dy, Gd and Y) complexes with hmp (anion of 2-hydroxymethylpyridine) and benzoate as ligands are reported. In these complexes, metal ions (M or Ln) occupy the four alternative corners of a distorted cubane with oxygen atoms…
At the beginning of the present century it has been demonstrated that nanocrystalline titanium (NC-Ti) can be fabricated by hydrostatic extrusion (HE) which is one of the severe plastic deformation method. NC-Ti obtained in such a way exhibited excellent mechanical properties. The influence of HE on the microstructure…
Oil palm shells (OPS) has been used as an aggregate in concrete mixture, replacing the normal sense aggregate in many countries, since long time, and it is still an important aggregate in terms of quantity used. In Malaysia, the development of using oil palm shell as lightweight aggregate in construction industry, esp…
The estimation of stress at a continuum point from the atomistic scale requires volume averaging over a region that contains this point. A hypothesis is put forth to obtain a lower bound for the size of this region based on an analogy to the Ising model. This hypothesis is tested on copper using two classical elastici…
Control of magnetic domain walls (DWs) and their propagation is among the most promising development directions for future information-storage devices. The well-established tools for such manipulation are the spin-torque transfer from electrical currents and strain. The focus of this paper is an alternative concept ba…
Cracking of hexagonal brass connector of a boiler tubing assembly caused leakage and interruption of the function of a water heating circuit. Destructive damage was provoked after two years in service. Visual examination, light and scanning electron microscopy coupled with local elemental energy dispersive X-ray spect…
Abstract The syntheses, structures and magnetic properties of the compounds of formula [Fe III (4‐Br‐sal 2 ‐trien)][Mn II Cr III (ox) 3 ] 0.67 Cl 0.33 · CH 3 OH_solvate ( 1 ), [Fe III (3‐Br‐sal 2 ‐trien)][Mn II Cr III (ox) 3 ] · (CH 3 CN) 2 ( 2 ), [Fe III (3‐Cl‐sal 2 ‐trien)][Mn II Cr III (ox) 3 ] · (CH 3 OH) 2 · (CH…
Synthesis of dendrimer-like star-branched poly(ethylene oxide)s (PEOs) with two and three generations having Zn(II) tetraphenylporphyrin (ZnTPP) moieties at the core and at each branching point has been successfully achieved through an iterative convergent approach harnessing “click chemistry”. In the first step, a fo…
Abstract The hexanuclear cobalt‐containing tungstovanadate complex, Na 17 [(Co(OH 2 )Co 2 VW 9 O 34 ) 2 (VW 6 O 26 )] · 31H 2 O ( 1 ) has been synthesized through reaction of cobalt nitrate, sodium tungstate, and V 2 O 5 in acetate buffer solution. The title compound has been characterized by X‐ray crystallography, el…
An ultra-short peptide Boc-L-Phe-L-Lys(Z)-OMe (Z=carbobenzyloxy) was shown to act as a highly efficient and versatile low molecular weight gelator (LMWG) for a variety of aliphatic and aromatic solvents under sonication. Remarkably, this simple dipeptide is not only able to form coiled fibres but also demonstrates sel…
A series of rare-earth zirconium chalcogenides Ln(2)ZrQ(5) (Ln = La, Sm, Gd; Q = S, Se) synthesized by using boron as the reducing reagent show unprecedented single-crystal's intrinsic voltage-dependent effects and order antiferromagnetically.
Polarization-resolved second-harmonic generation (PR-SHG) microscopy is described and applied to identify the presence of multiple crystallographic domains within protein-crystal conglomerates, which was confirmed by synchrotron X-ray diffraction. Principal component analysis (PCA) of PR-SHG images resulted in princip…
The interplay between superconductivity and Eu${}^{2+}$ magnetic moments in EuFe${}_{2}$(As${}_{1\ensuremath{-}x}$P${}_{x}$)${}_{2}$ is studied with electrical resistivity measurements under hydrostatic pressure on $x=0.13$ and $x=0.18$ single crystals. We can map hydrostatic pressure to chemical pressure $x$ and show…
We have performed molecular simulations to investigate morphologies and the phase diagram of the self-assembled triblock Janus nanoparticle confined to nanotubes. The triblock Janus nanoparticle is decorated with two hydrophobic caps at the north and south poles with a tunable area, separated by an electrically charge…
Silk scaffolds having biomimetic hierarchical porous structures were achieved by carefully tuning liquid-liquid separation in regenerated silk fibroin solutions. Such scaffolds show greatly enhanced cellular responses.
We report on the improvement of the electronic characteristics of monolayer graphene field-effect transistors (FETs) by an interacting capping layer of a suitable fluoropolymer. Capping of monolayer graphene FETs with CYTOP improved the on-off current ratio from 5 to 10 as well as increased the field-effect mobility b…
Nanoparticle-based gene delivery systems may be more efficient for administration of therapeutic genes to solid tumors and cancer metastases, owing to the numerous advantages in terms of enhanced tissue penetrability, improved cellular uptake and targeted gene delivery to the cells of interest compared with other gene…
