The first records of Libellula pulchella from México and for Phyllogomphoides albrigthi from Coahuila are reported. These records extend the known geographic range of Libellula pulchellabeyond south of Texas and Phyllogomphoides albrigthi beyond west of Nuevo León. The specimens were collected in the Cuatro Ciénegas B…

On page 5124, Rodney S. Ruoff, Litao Sun, and co-workers report a pH-mediated hydrothermal reduction and moulding of graphene oxide to realize high density (up to 1.6 g/cm3), compact 3-D graphene macrostructures with desired shapes. The present structures have a compressive strength of 361 MPa (6 times higher than con…
In order to discover how the grafted side chains affect the crystallization of the graft copolymers, the ternary-monomer solid-phase graft copolymers of polypropylene (PP; PPSM) were synthesized by solid-phase grafting of maleic anhydride, styrene and butyl acrylate onto PP. The Jeziorny and Mo methods were used to in…
The purpose of this research was to study the adsorption behavior of diethyl and dimethyl malonate esters on the single-walled carbon nanotubes (SWCNTs), by Uv-Vis lambda 45 spectrophotometer. In this work we used five concentrations of esters (100-150-200-250-300 µgml -1 ). In all experiments the condition such as ad…
Composite materials are materials constituted of two or more immiscible constituents to obtain properties which cannot be attained by the individual components. This chapter describes general trends in the use of biomass in composite materials used as the continuous polymer matrix, reinforcing fibres or fillers and as…
The origin of a mysterious phase transition at 6.5K in the skutterudite PrFe4P12 has long been a subject of intensive research. Recent microscopic experiments such as NMR, X-ray, and neutron scattering commonly showed that the local symmetry around each Pr site is unbroken below the transition temperature, although th…
A series of heteroleptic chelate copper(II) complexes of the type [Cu(L)(acac)]X where acac = acetylacetonate; L = N,N′-1,6-bis(2-fluorophenyl)-2,5-diazahexane; X=CIO4- , BPh4- , PF6- , and BF4- have been prepared and characterized by elemental analyses, IR and UV-Vis spectroscopies, and molar conductance measurements…
Under the project on high burnup nuclear fuel development using erbium as a burnable poison, a series of experiments were performed at the Kyoto University Critical Assembly. The experimental results have formed the basis for this study which aims to analyze the suitability of various evaluated nuclear data libraries…
One-dimensional (1D) semiconducting nanostructures, as both interconnections and functional units in fabricating electronic, biological/chemical sensors, optoelectronic, electrochemical, and electromechanical devices, attract immense interest. However, all those 1D semiconducting nanostructures are sensitive to both v…
An analytical method for control of the strength of a grillage (gross panel) under unidirectional in-plane axial load is proposed. It allows us to solve the following tasks: (i) calculation of the critical stiffness of transverse girders, (ii) calculation of the maximum unidirectional in-plane compression load when th…

The influence of regression (partial dissolution) effects on the temperature dependence of nucleation rate in a binary solid solution has been studied theoretically. The results of the analysis are compared with the predictions of the simplest Volmer–Weber theory. Regression effects are shown to have a strong influenc…
We present molecular dynamics study of a generic (coarse-grained) model for single-polymer diffusion confined in a corrugated cylinder. For a narrow tube, i.e., diameter of the cylinder δ < 2.3, the axial diffusion coefficient D(∣∣) scales as D(∣∣) ∝ N(-3∕2), with chain length N, up to N ≈ 100 and then crosses over to…
Two dinuclear CuII complexes based on a diazecine ligand were characterized by X-ray diffraction, one of which includes the rare CuII–F bond, resulting from dissociation of a BF4− ion. The F− ligands actively participate in the crystal structure, behaving as acceptors for hydrogen bonding.
Scanning transmission electron microscopy (STEM) in the dark-field mode of operation is a technique regularly used to record high-contrast images from isolated macromolecular assemblies at nanometer resolution. Dark-field STEM images are unique in that they can be readily quantified to provide information on the mass…
Abstract Nowadays, the development of new green technologies has been promoted worldwide both by public and private institutions. In this context the research on microbial fuel cells (MFC) represents a promising alternative to carbon based energy sources. Unfortunately, this technology has been always affected by too…
We investigate colloidal Fe(3)O(4) nanocrystals as a catalyst system for carbon nanotube (CNT) growth that allows for decoupling the CNT growth step from the catalyst shaping and activation step. The system consists of 6.4 nm Fe(3)O(4) nanocrystals synthesized using a solution-based thermal decomposition reaction and,…
