This work describes a novel method based on a metal salt-free system to synthesize a Li–Al–CO3 layered double hydroxide (LDH) by simply adding powdered AlLi intermetallic compound (IMC) to a stirred water-bath at ambient temperature and atmosphere. The AlLi powder in the water-bath hydrolyzed strongly, subsequently fo…
The properties of water change significantly across the critical point of water and these changes affect the degradation behavior of constructional alloys. The corrosion behavior of nickel-base alloys is investigated across the critical temperature of water at a constant pressure in aqueous solutions. At subcritical t…
Zinc-Aluminum and Zinc-Silver alloys were solidified in horizontal and vertical form and the results obtained analyzed. Thermal parameters such as the cooling rates, the liquidus and solidus interphase velocities, and the temperature gradients were determined. The velocity of the liquidus interphase is greater than or…

We systematically study magnetic correlations in graphene within Hubbard model on a honeycomb lattice by using quantum Monte Carlo simulations. In the filling region below the Van Hove singularity, the system shows a short-range ferromagnetic correlation, which is slightly strengthened by the on-site Coulomb interacti…
Quasi-elastic neutron scattering, neutron diffraction as well as in situ and ex situ Raman studies were performed on the proton conducting (Ba/Sr)Zr 1- x Ln x O 3-δ dense ceramics. The results confirm the homogeneous distribution of the bulk protonic species, their variable content as a function of Ln content and samp…
Fabrications of one-dimensional (1D) nanostructures and magnetic/semiconducting heterostructures have recently been the limelight of study to establish functional nanodevices with their size and dimensionality influencing the material properties of a system. In this regard, Cr substituted ZnO nanorods were prepared un…
High temperature activation of carbon nanotubes (CNTs) provides a new and highly versatile functionalisation strategy. The reaction allows the attachment of a wide variety of functional species onto the nanotube surface at grafting ratios between 1–8 wt%, whilst maintaining the intrinsic properties of the untreated ma…
Polyethylene (PE) was modified by an Ar plasma. The plasma-activated PE surface was grafted with poly(ethylene glycol) (PEG, molecular weight 300 and 20 000). The depth profiles of the oxygen in the modified PE samples were determined using Rutherford Backscattering Spectroscopy (RBS). The changes in the surface wetta…
High-quality, monodisperse, and size-controlled Fe(3)O(4), Ag, and bifunctional Fe(3)O(4)/Ag heterodimer nanocrystals (NCs) have been synthesized successfully. In the synthesis of Fe(3)O(4) NCs, dodecanol was chosen as the substitute of 1,2-hexadecanediol and "size control" was achieved by simply adjusting the proport…
We study the effect of the molecular charge transfer on the electronic structure of metallic (5,5) and semiconducting (8,0) single-walled carbon nanotubes (SWNTs) induced by surface adsorption of various organic donor-acceptor molecules of different affinities using ab initio density functional theory. Our results, ob…
Esta pesquisa teve por objetivo avaliar o potencial de utilização de madeira de Schizolobium amazonicum (Paricá) e Cecropia hololeuca (Embaúba) para produção de painéis aglomerados. Foram produzidos painéis experimentais com densidade nominal de 0,70 g/cm³, utilizando a resina uréia-formaldeído e partículas de madeira…
Single-crystalline ultrathin nanorods of CeO2 with uniform diameters of ca. 1.5 nm have been synthesized via an oriented attachment process based on a facile solution-based approach.
Reactions of MnX(2) meltsalt (X = Cl and ClO(4)) and a quinquedentate Schiff base ligand together with its coligand azides in MeOH produced the unprecedented assembly of novel octa- and hexadecanuclear manganese clusters containing two and four alternant tetrahedral Mn(III)(3)Mn(II) cores bridged by Schiff base ligand…
The mononuclear Fe(II) phthalocyanine 2 and ball-type homobinuclear Fe(II)-Fe(II) and Cu(II)-Cu(II) phthalocyanines, 3 and 4 respectively, were synthesized from the corresponding 4,4'-[1,1'-methylenebis-(naphthalene-2,1-diyl)]bis(oxy)diphthalonitrile 1, and then ball-type heterobinuclear Fe(II)-Cu(II) phthalocyanine 5…
The catalytic activity of zirconia supported lacunary undecatungstophosphate was evaluated for solvent free oxidation reactions. The catalyst was proved to be successful for clean and green oxidation reactions which can be useful in waste minimization. The superiority of the present catalyst lies, especially, in obtai…
A technique is described for performing solid phase extraction (SPE) at a semi-microscale. 10 mg of electrospun polystyrene fibers (average diameter 2.7 µm) were packed into a SPE barrel to form a disk (5 mm × 1 mm). The device was employed to evaluate the extraction of four steroids: prednisone, hydrocortisone, corti…
We investigated the pressure driven flow of concentrated colloidal dispersions in a converging channel geometry. Optical microscopy and image analysis were used to track tracer particles mixed into dispersions of sterically stabilized poly(methyl methacrylate) (PMMA) spheres. The dispersions were drawn into a round 0.…
A new functionalized bis-pyrazol-pyridine ligand has been prepared by reaction with hydrazine of the corresponding bis-β-diketone precursor, also unprecedented. The aerobic reaction of this ligand with ferrous thiocyanate in the presence of ascorbic or oxalic acid affords the dinuclear complex of seven-coordinate Fe(I…
We report on the single-pot fabrication of ordered mesoporous crystallized titania films doped with gold. Au is incorporated in TiO2 films by adding to the coating solution precursors such as AuCl3 or monodisperse Au113+ nanoclusters, and Au nanoparticles are formed by calcination. A systematic study is performed to c…
