-
(Elsevier, 2018)In this paper, a new approach is developed for structural shape optimization, which consists in coupling the particle swarm optimization (PSO) algorithm and the isogeometric boundary element method (IGA-BEM). The IGA-BEM ...
-
(2012)Optically active poly(amide-imide) oligomers were synthesized by direct polycondensation between an aromatic diamine and a dicarboxylic acid both containing a diphenylsilylene unit. The reaction was carried out using ...
-
(2012)Inaccurate wiring and synaptic pathology appear to be major hallmarks of schizophrenia. A variety of gene products involved in synaptic neurotransmission and receptor signaling are differentially expressed in brains of ...
-
(Elsevier, 2013)I build a large-firm model of the labor market with matching frictions and firm turnover. Firms hire both labor and capital. The model allows me to assess the impact of two regulatory frictions on unemployment: i) the ...
-
(American Chemical Society, 2018)In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on Ce-III and containing Co-II or Cu-II cations, assembled by the bifunctional ligand 1H-imidazole-4 ...
-
(Springer, 2020)BiFeO3 was synthesized by conventional solid-state reaction method, and its structural, vibrational, electrical, ferroelastic, and multiferroic properties were studied. X-ray diffraction analysis and Rietveld refinement ...
-
(ELSEVIER, 2006-09-15)The monovacancy and the divacancy in single-walled carbon nanotubes (CNTs) are addressed by spin-density functional calculations. We study these defects in four nanotubes, the armchair (6,6) and (8,8) and the zigzag (10, ...
-
(2016)Transition metal alloy nanoparticles are of interest both theoretically and experimentally, particularly due to their potential technological applications, and to their novel structural and magnetic properties in the ...
-
(American Chemical Society, 2017)© 2017 American Chemical Society. Different polymorphs of Nb2O5 can be obtained depending on the pressure and temperature of calcination leading to different catalytic properties. Two polymorphs of niobia, T-Nb2O5 and ...
-
(Elsevier, 2018-09)Herein, we report the structure, morphology, optical and magnetic properties of novel Ag3(2+x) InxNb4-xO11+delta (0.25 <= x <= 1.0; Al-A4) nanoparticles prepared by sol-gel technique. The samples were studied using X-ray ...
-
(Elsevier GmbH, 2018)Amorphous indium tin oxide (ITO) thin films with reduced to 50 mass% indium oxide content were prepared by direct current (DC) sputtering of ITO target in mixed argonoxygen atmosphere onto glass substrates preheated at ...
-
(Public Library of Science, 2015)Reactors found in nature can be described as micro-heterogeneous systems, where media involved in each micro-environment can behave in a markedly different way compared with the properties of the bulk solution. The ...
-
(AMER CHEMICAL SOC, 2004-07-06)The structure and aggregation number of a discotic lyotropic liquid crystal, prepared from tetradecyltrimethylammonium chloride (TDTMACI)/decanol (DeOH)/NaCI/H2O, have been examined using fluorescence quenching of pyrene ...
-
(Elsevier S.A., 2003)The title compound corresponds to a molecular product of the hydrothermal reaction of CuCl2, Zn, and BIPY (BIPY=2,2′-bipyridine) in the presence of phosphoric acid. The structure of the neutral complex Cu 4(μ2-Cl)4(BIPY)2 ...
-
(Nature Publishing Group, 2018)Understanding the factors that modulate bacterial community assembly in natural soils is a longstanding challenge in microbial community ecology. In this work, we compared two microbial co-occurrence networks representing ...
-
(IOP PUBLISHING LTD, 2010-09)The late stages of evolution of the primordial circumstellar disks surrounding young stars are poorly understood, yet vital to constraining theories of planet formation. We consider basic structural models for the disks ...
-
(1987)Some aspects of the reproductive biology of the glossiphoniid leech, Theromyzon rude, under laboratory conditions, and the staging and structure of its uncleaved egg were studied. Sexually mature animals form breeding ...
-
(1990)Reorganization of the fertilized egg during completion of the first meiotic division was studied in the glossiphoniid leech Theromyzon rude. Rotation of the meiotic spindle, presumably as a result of changes in the length ...
-
(ELSEVIER SCIENCE BV, 1998-11-26)A gene encoding laccase has been isolated from a genomic library of the white-rot basidiomycete Ceriporiopsis subvermispora constructed in Lambda GEM-ii. This gene (Cs-lcs1) contains an open reading frame of 2215 bp, ...
