Nano-composite ceramic composing of (La0.66Gd0.34)2Zr2O7 (LGZ) and (Zr0.76Gd0.24)O1.88 (GSZ) phases is synthesized form in-situ reaction and is consolidated by spark plasma sintering. It has a thermal conductivity about 20 and 35% lower than that of single phase LGZ and GSZ materials, respectively. The lower thermal c…
The 14th Frontiers of Electron Microscopy in Materials Science (FEMMS) meeting was held at the Mantra Lorne, on Australia’s Great Ocean Road, from the 8th to the 13th of September, 2013. The meeting, attended by 132 delegates, including 40 invited speakers, brought together established researchers, instrument manufact…
Abstract Three ZnII and CdII complexes with Y‐shaped dicarboxylate ligands, namely [Zn(L1)(2,2′‐bpy)2(H2O)]·2H2O (1), [Zn(L1)(bpp)(H2O)] (2), and [Cd(L1)(H2O)]·H2O (3) [H2L1 = N‐phenyliminodiacetic acid, 2,2′‐bpy = 2,2′‐bipyridine, bpp = 1,3‐bis(4‐pyridyl)propane] were synthesized and characterized by elemental analys…
An adroit design of pore‐forming system is required to achieve a porous ceramic matrix with high permeability and adequate mechanical strength. This work developed a hybrid pore‐forming regime constructed in the green body (dense powder packing) of yttria stabilized zirconia (YSZ) through the condensation polymerizati…
Abstract The anisotropic band structure and electrical resistivity under uniaxial strain were investigated for the moderately dimerized molecular conductor β‐(meso‐DMBEDT‐TTF)2PF6 [DMBEDT‐TTF = dimethylbis(ethylenedithio)tetrathiafulvalene], which has an intermediate electronic state between 3/4‐filled and effective 1…
The present study concerns a development of cement-free concrete using ground granulated blast-furnace slag (GGBS) with alkali-activators such as KOH, NaOH, and Ca (OH)2. To find out the development among three different activators, the concentration of hydroxyl ion was kept 0.5%, 1.0%, 1.5%, 2.0% and 3.0% by weight o…
Non-linear FEM calculations are indispensable when important technical information like operating performance of a rubber component is desired. Rubber bumpers built into air-spring structures may undergo large deformations under load, which in itself shows non-linear behavior. The changing contact range between the pa…
The crystal structure of the title compound, Tb2Ni7, was redetermined from single-crystal X-ray diffraction data. In comparison with previous studies based on powder X-ray diffraction data [Lemaire et al. (1967). C. R. Acad. Sci. Ser. B, 265, 1280-1282; Lemaire & Paccard (1969). Bull. Soc. Fr. Mineral. Cristallogr. 92…
A novel glucoconjugate of the peptidic fragment of cryptophycin-24 was prepared through the replacement of the leucic acid residue with L-leucine and the functionalisation of tyrosine residue with glucose.Those modifications lead to a novel protected tripeptide fragment of cryptophycin-24.
:The removal of captan (N-trichloromethyl thio tetrahydropthalamide) from aqueous solution was studied by using super-paramagnetic nano iron oxide loaded poly (styrene-co-acrylic acid) hydrogel as adsorbent by batch and column method. Adsorption equilibrium was investigated as a function of initial pH, adsorbent dose,…
Predicting the dynamic response of a floating and submerged structure subjected to underwater explosion is greatly complicated by the explosion of a high explosive, propagation of shock wave, bubble-pulse, complex fluid-structure interaction phenomena and the dynamic behavior of the floating structures. A numerical si…
Secondary electron emission with very low kinetic energy (KE) has been measured in the Ne 1s photoexcitation region. A new decay channel for Auger transitions following Ne 1s to 3p excitation has been identified using a two-dimensional mapping technique, in which slow Auger electron signals are displayed as functions…
Se resume la información disponible sobre caracterización de arcillas en suelos de Costa Rica desde 1931 hasta el presente, descrita en 84 trabajos con 520 observaciones hasta el 2014. La discusión se basa principalmente en la mineralo- gía de arcilla de los horizontes superficiales del suelo, aunque se menciona la mi…
Abstract The dynamics of flowing, concentrated suspensions of non-colloidal particles continues to surprise, despite decades of work and the widespread importance of suspension transport properties to industrial processes and natural phenomena. Blanc, Lemaire & Peters (J. Fluid Mech., 2014, vol. 746, R4) report a stri…
In Klebsiella pneumoniae, glycerol dissimilation involves parallel oxidation and reduction pathways. Oxidation pathway provides adenosine triphosphate (ATP) and cofactors to sustain cell growth, while reduction pathway presents 3-hydroxypropionic acid (3-HP) and 1,3-propanediol(1,3-PDO), which are commercially attract…
A novel NixCoyOz–C composite has been synthesized by a one pot in situ hydrothermal method with rod-like Ni@C (Ni nanoparticles wrapped by C) as support. The structure and morphology of the composites are characterized by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microsc…
In this work, the influence of organoclay incorporation along with silane grafting of high‐density polyethylene (HDPE) on compatibilization and morphology of HDPE/(polyamide‐6) (PA6) blends was investigated. Analysis by Fourier‐transform infrared spectroscopy was done for the investigation of grafting efficiency of sp…
Kelvin probe force microscopy at air in the dark and under illumination by visible light was performed for electrodeposited porous ZnO films, which were sensitized by the indoline dye D149. A contact potential difference was measured that confirmed electron injection into the semiconductor matrix and their subsequent…
Type I collagen fibrils have circular cross sections with radii mostly distributed in between 50 and 100 nm and are characterized by an axial banding pattern with a period of 67 nm. The constituent long molecules of those fibrils, the so-called triple helices, are densely packed but their nature is such that their ass…
Molecular dynamic simulation of a faceted ice-Ih crystal with the largest dimension of 0.06 µm in a vacuum is performed by employing the TIP4P intermolecular potential at temperatures Tm − 23, Tm − 13, and Tm − 1 K, where Tm is the melting point of the TIP4P bulk ice. We thereby observe at all the temperatures that th…
