A 20 barrel solid hydrogen pellet injector, which is able to inject 20 cylindrical pellets with a diameter and length of between 3.0 and 3.8 mm at the velocity of 1200 m/s, has been developed for the purpose of direct core fueling in LHD (Large Helical Device). The in situ pipe gun concept with the use of compact cryo…
The objective of this article is to systematically present the emerging understanding that 3D porous scaffolds serve not only as structural templates for tissue fabrication but also provide complex signaling cues to cells and facilitate oxygen and therapeutic agent delivery. Strategies in the field of tissue engineeri…
Although many proteins are recognized to undergo folding via an intermediate, the microscopic nature of folding intermediates is less understood. In this study, ¹⁹F NMR and near-UV circular dichroism (CD) are used to characterize a transition to a thermal folding intermediate of calmodulin, a water-soluble protein, wh…
We present the results of the pressure dependence of the superconductivity of the inorganic electride 12CaO·7Al2O3:e− (C12A7:e−) single crystal through the ac-susceptibility measurement under high pressure. C12A7:e− has the cage structure and the density of states derived from the cages may play an important role in t…
Switchable surfactants, particularly those triggered by CO2 used for switchable foam control, are relatively less documented. In this article, the foaming performance of 2-alkyl-1-hydroxyethylimidazolinium bicarbonate cationic surfactants (HEAIBs) was investigated for the first time. The foaming properties of these su…
BaCo 2 X 2 O 7 (X = P, As) compounds are formed of chains of Co 2+ O 8 dimers. In a first approximation, the structural chains appear strongly isolated, which gives a pronounced one-dimensiona (1D) magnetic character to the systems. GGA+U calculations show ferromagnetic (FM) exchanges inside the dimers and predominant…
A detailed physical picture of necking phenomenon in semi-interpenetrating double-network (SIDN) hydrogels was developed using the tensile mechanics of DN hydrogels synthesized from 3-sulfopropyl acrylate potassium salt (SAPS) and acrylamide (AAm) with different molecular weights. Uniaxial tensile tests for DN hydroge…
Literature data and own experimental results on structural characteristics of the halide ions nearest surrounding in the aqueous electrolyte solutions under standard conditions has been summarized. Structural parameters like coordination number, interparticle distance, and ion association type have been discussed. It…
PURPOSE: To evaluate the effect of different cylindrical and close-conforming receive-only array designs on spin excitation and specific absorption rate (SAR) of a 7 T transmit-only head coil. MATERIALS AND METHODS: We developed finite difference time domain (FDTD) models of different receive-only array geometries. Cy…
Solid lipid nanoparticles (SLNs) have recently emerged as nontoxic, versatile alternatives to traditional carriers (liposomes, polymeric nanoparticles) for drug delivery. Because SLNs are composed of a solid lipid core, they offer significant protection against chemical degradation of their drug cargo and offer the po…
The work presented in this paper reports on the water sorption properties of thermally modified wood, densified wood and wood modified using a combination of the two methods. The paper presents new findings concerning the sorption isotherms and sorption kinetics behaviour. The sorption kinetics is analysed in terms of…
In the past decade there has been an explosive growth in the consumption of sapphire driven by the demands of the next generation of energy ecient general lighting based on GaN LEDs. This application requires orienting these rhombohedral corundum crystals such that the substrate surface is the c-plane; a basal plane d…
Owing to the complex behavior of ultrasound-induced bubble clouds (nucleation, linear and nonlinear oscillations, collapse), acoustic cavitation remains a hardly controllable phenomenon, leading to poorly reproducible ultrasound-based therapies. A better control of the various aspects of cavitation phenomena for in vi…
Use of reclaimed asphalt pavement (RAP) has increased considerably over the past few years; approximately 85% of the RAP available is used within either hot mix asphalt (HMA) or warm mix asphalt (WMA). Within this time frame a number of research efforts have been performed, but most efforts have focused on RAP content…
Entwässert nach Plan: Ein Nanokompositkatalysator für die Dehydratisierung von Fructose zu der Plattformchemikalie 5-Hydroxymethylfurfural (HMF) wurde gezielt entworfen und hergestellt. Durch Einlagerung und Vernetzung von Polyvinylpyrrolidon in den säurefunktionalisierten Mesoporen eines Silicats wird das Tautomereng…
Multiammonium-Tenside wirken auch dann als Oberflächenbeschichtung in der Synthese von Zeolith-Nanopartikeln, -Nanostäben und -Nanoschwämmen, wenn übliche einwertige Tenside versagen. Mithilfe dieser Tenside hergestellte Mordenit-Nanostäbe sind saure Katalysatoren der Cumolsynthese mit verlängerter Lebensdauer.
The safety documentation for ITER, including the Preliminary Safety Report, was submitted to the French nuclear safety authorities in March 2010 as part of the procedure for licensing the facility as a basic nuclear installation in France. The documents were then examined by the authorities and their technical advisor…
Endohedral metallofullerenes (EMFs) encapsulating divalent metal ions have received limited attention because of their low production yields. Here, we report the results of structural determination and chemical functionalization of a typical divalent metallofullerene, Yb@C84(II). Single-crystal X-ray crystallographic…
This study examines the tissue engineering potential of type I collagen cross-linked in the presence of hydroxyapatite (HAp). Scaffolds were prepared by controlled freezing followed by lyophilization of composite mixtures of collagen and HAp in acetic acid, followed by cross-linking with 0.3% glutaraldehyde. Scaffolds…
BACKGROUND: Functionalized fullerenes, such as polyhydroxy fullerenes (PHF), have attracted particular attention due to their water solubility and their potential application in tumor imaging and therapy as carbon nanomaterials. In this study, the sonodynamically-induced antitumor effect of PHF was investigated. MATER…
