Hemp (Cannabis Sativ L.) is an important lignocellulosic raw material for the manufacturing of cost-effective environmentally friendly composite materials. However, traditional decortication processes using hammer mill, cutterhead or crushing rollers often generate low fiber purity, do not allow for an entire separati…
Dreimal ungewöhnlich: Im tetramorphen PdCl2-System zeigen drei der vier Phasen das ungewöhnliche Verhalten einer negativen thermischen Ausdehnung in einer Richtung. Die beiden Hochtemperaturphasen α-PdCl2 und δ-PdCl2 (links) enthalten ebene Bänder kantenverknüpfter PdCl4-Quadrate, während in der Tieftemperaturphase γ-…
In this work, it was studied a partial characterization of a Nitinol actuator M-type alloy, manufactured by Memory- Metalle. From the results obtained in differential scanning calorimetry, it was shown the temperatures of phase transformation where occur the remarkable properties, shape memory effect and super-elastic…
In the title compound, [CuMoO(4)(C(8)H(20)N(4))]·H(2)O, the Cu(II) atom is coordinated by four N atoms of the 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) ligand and one O atom of the molybdate unit in a distorted square-pyramidal environment. The water mol-ecules are linked to the complex unit to form centrosymmetric d…
Abstract We use ab‐initio calculations based on the augmented spherical wave method within density functional theory to study the magnetic ordering and Fermi surface of BaFe2As2, the parent compound of the hole‐doped iron pnictide superconductors (K,Ba)Fe2As2, for the tetragonal I4/mmm as well as the orthorhombic Fmmm…
Abstract A series of polyimide (PI)/silica hybrid films were prepared by sol–gel method, using hydrolyzed tetraethoxysilane and poly amic acid‐imides (PAA‐Is), which were different imidization degree controlled by chemical imidization method. The imidization degree was characterized by Fourier transform infrared spect…
During decommissioning of nuclear facilities, it is generally thought that the risk is relatively low after high activity inventory such as the spent fuel is removed. However, dismantlement works may be carried out with nonmultiple barriers with a nonregular process depending mainly on human activities. Moreover, fire…
Using continuity, we derive a renormalized Hamiltonian from the parent $t\text{\ensuremath{-}}J$ model to describe the properties of underdoped cuprates. The theory is constrained to agree with the behavior at half filling, which is well described by the Arovas-Auerbach valence bond state in which bosonic spinons are…
In the centrosymmetric binuclear title compound, [Zn(2)Cl(4)(C(20)H(17)N(3))(2)], the coordination geometry of the Zn(II) ion can be described as a distorted ZnN(2)Cl(3) trigonal bipyramid (τ = 0.89), arising from the N,N'-bidentate ligand, a terminal chloride ion and two bridging chloride ions. The N atoms occupy one…
The asymmetric unit of the title compound, (C(11)H(18)N(2))(2)[CdCl(6)]·2H(2)O, consists of one 1-benzyl-piperazine-1,4-diium dication, one water mol-ecule and one-half of a [CdCl(6)](4-) anion, located on an inversion centre. The crystal packing is governed by an extensive three-dimensional network of inter-molecular…
We present results from the Extended X-ray Off-Plane Spectrometer (EXOS) sounding rocket payload. The payload was launched on November 13, 2009 and successfully obtained a spectrum of the Cygnus Loop Supernova Remnant. The instrument observed in the ~20 - 110 Angstrom bandpass with high resolution (~50) by utilizing a…
Abstract The flammability and mechanical properties of Al(OH)3/BaSO4/polypropylene (PP) composites were investigated. The flow, morphological, and thermal properties were also analyzed by melt flow index (MFI), Scanning electron microscopy (SEM), and Differential scanning calorimeter (DSC) studies, respectively. Total…
Several models of the electronic spectrum in the pseudogap state of underdoped cuprates have been proposed to explain photoemission and tunneling measurements, which reveal only truncated Fermi pockets instead of a full metallic Fermi surface. We consider the transport properties expected of four physically distinct m…
BT1062 from Bacteroides thetaiotaomicron is a homolog of Mfa2 (PGN0288 or PG0179), which is a component of the minor fimbriae in Porphyromonas gingivalis. The crystal structure of BT1062 revealed a conserved fold that is widely adopted by fimbrial components.
Abstract This study aims to synthesize poly(methylsilyne) by electrochemical reduction of methyltrichlorosilane at a constant potential of −6 V, while investigating the effects of parameters such as the nature of the electrode, solvent and supporting electrolyte, the monomer/solvent ratio, and the reaction time on the…
Purpose This paper's aim is to focus on the design, manufacture and test of a stiffened panel in composite material with integrated longitudinal foam‐filled stiffeners, spar and rib caps, using one‐shot liquid infusion (LI) process, reducing weight and number of subparts respect to metallic reference baseline P180 Ava…
The ability of thin conductive polythiophene layers to dissipate electrons in electron-beam lithography (EBL) process on bulk zinc oxide (ZnO) samples is shown. High energy electron-beam exposure of relatively thick (650 nm-thick) hydrogen silsesquioxane (HSQ) negative-type resist deposited on ZnO was investigated for…
Momentum dependent inelastic plasmon scattering can be measured by electron energy loss in a transmission electron microscope. From energy filtered diffraction, the characteristic angle of scattering and the cutoff angle are measured, using a thin film of aluminum as a model test. Rather than deconvolving the data (as…
Zwei Wege zum Ziel: Hoher Druck oder nanoskalige Synthese führen zum gleichen Indiumoxid-Polymorph, wofür die Untersuchungen von Farvid et al. eine Erklärung lieferten: Das metastabile Hochdruckpolymorph rh-In2O3 wird in Nanopartikeln oberflächenspannungsinduziert stabilisiert, während es bei größeren Partikeln als st…
Abstract Filter cake washing is a purification process during solid/liquid separation which is applied to various particulate products with different product properties. A generalization of the washing strategy is in most cases not possible nor is it reasonable due to product diversity. This paper presents an overview…
