We have grown Ge3Mn5 clusters by codepositing germanium and manganese atoms on Ge(001) substrates using low temperature molecular beam epitaxy and further annealing the films at high temperature. Clusters are spherical and randomly distributed in the germanium film in epitaxial relationship with the diamond lattice. T…
This paper presents a method to improve the performance of supercapacitors fabricated using binderless composite electrode monolith (BCMs) from self‐adhesive carbon grains (SACG) of fibers from oil palm empty fruit bunches. The BCMs were prepared from green monoliths (GMs) contain SACG, SACG treated with KOH (5 % by w…
The tensile strength of concrete material increases with the strain rate. Dynamic tensile strength of concrete material is usually obtained by conducting laboratory tests such as direct tensile test, flexural test, spall test or splitting test (Brazilian test). Some codes of practice such as Comite Euro-International…
Abstract. Powder diffraction plays a central role in the characterization of light metal tetrahydroborates (borohy-drides), novel boron based hydrides recognized as a poten-tial solution for hydrogen storage. Numerous novel BH4 based materials have been investigated during the past few years and this class of material…
We discuss about the antibacterial activities of Silver nanoparticles and compare them on both Gram negative and Gram positive bacteria in this investigation. The activities of Silver nanoparticles synthesized by electrolysis method are more in Gram (-) than Gram (+) bacteria. First time, we increase its antibacterial…
A variety of sophisticated approaches have been established to obtain stable dispersions of graphene. To overcome the π-π stacking energy between individual graphene layers in graphite crystals an activation step needs to be implemented. Damaging the crystal lattice planes with oxidants is one viable option. Likewise,…
2 – methyl -3(trifluromethyl) aniline was tested as a corrosion inhibitor for mild steel in 1 M HCl and 0.5 M H2SO4 separately using mass loss and electrochemical studies. The inhibition efficiencies were evaluated at different concentrations of the inhibitor. The inhibition efficiency increased with increase in inhib…
The much attention is given to some possible results of the nanomaterials irradiation such as the interphase role as the radiation defect sinks, the nanostructure amorphization, the nanocrystallization of amorphous state, the alloying component segregation, and the enhance- ment of recrystallization. The radiation eff…
Aluminium pillared montmorillonites from Indonesian natural montmorillonite has been prepared using Al 13 Keggin ion pillaring precursor in varied concentrations. Herein we studied their characterization and catalysis application for esterification reaction. X-ray diffraction (XRD), energy dispersive x-ray analysis (E…
The paper presents the recent advances of water-gas shift process using supported nickel catalysts. The effect of different supports, nickel loading, gas hourly space velocity, dopant materials, on the catalyst activity, H2 yield, and H2 selectivity are discussed. Ceria promoted nickel catalyst supported on powder alu…
In this Perspective article we give an account of the application of total scattering methods and pair distribution function (PDF) analysis to the investigation of materials for clean energy applications such as materials for solid oxide fuel cells and lithium batteries, in order to show the power of this technique in…
We report the synthesis and the self-assembled morphologies of a series of new rod-coil diblock copolymers, poly[2,7-(9,9-dihexylfluorene)]-b-poly(4-vinylpyridine) (PF-b-P4VP). The rod-coil diblock copolymers were synthesized via Suzuki coupling reaction and living anionic polymerization. Probing by transmission elect…
This study reports the electrochemical performance and stability of MnO x -multiwall carbon nanotubes (MWCNTs) nanocomposite/Ni pseudocapacitor electrodes fabricated by a modified electrophoretic deposition (EPD) method. The nanocomposite electrode consisting of highly dispersed manganese oxide on MWCNTs was synthesiz…
Abstract Based on the thermodynamic calculations extrapolated from the corresponding binary sub-systems, four decisive alloys in the Fe–Mg–Mn system and three in the Fe–Mg–Ni system were selected and prepared using a powder metallurgy method to measure the isothermal sections at 500 8C in both systems. The prepared sa…
An original fluorescent dyad has been prepared, featuring a 1,8-naphthalimide chromophore linked to a fluorescent tetrazine. This bichromophore benefits from the good absorption coefficient of the imide, and displays a quasi complete energy transfer to the tetrazine, followed by its fluorescence emission. This allows…
Visible- and near-infrared-emitting quantum-dots (QDs) were readily encapsulated with high yields into PEGylated, poly(alkyl cyanoacrylate) nanoparticles (NPs) by self-assembly in aqueous solution. The resulting QD-loaded NPs were efficiently purified and characterized by transmission electron microscopy, dynamic ligh…
Two Fe(II) complexes fac-[Fe(II)(HL(n-Pr))(3)]Cl·Y (Y = AsF(6) (1) and BF(4) (2)) were synthesized, where HL(n-Pr) is 2-methylimidazole-4-yl-methylideneamino-n-propyl. Each complex-cation has the same octahedral N(6) geometry coordinated by three bidentate ligands and assumes facial-isomerism, fac-[Fe(II)(HL(n-Pr))(3)…
Nanoribbon structures have the feature of sharp edges, providing the marked geometrical field enhancement for field emitters even in a randomly arranged thin film structure. In this work, the field emission of SnO2 nanoribbons with thin walls (10–30 nm) prepared on a large scale via a rapid oxidation reaction is inves…
Here we present a two-component self-assembling system employing the interaction of aromatic groups (Fmoc) to construct nanoparticles. Spherical particles of around 70 nm were formed spontaneously by a simple trigonal Fmoc-conjugate, which were then stabilized by Fmoc-dipeptides at physiological pH in aqueous solution…
Single-crystalline Mn-doped ZnO nanowires of different compositions were synthesized by chemical vapor deposition. Their micro-structures were characterized by high-resolution transmission electron microscopy and X-ray diffraction. The results reveal that Mn doping leads to production of planar and point defects, latt…
