This specification defines essential criteria for all material combinations in boron-based neutron-absorbing material systems used for nuclear spent fuel storage racks in nuclear light water reactors, spent-fuel assemblies, or disassembled components. The boron-based neutron absorbing materials normally consist of met…
It is well known that amorphous solids display a phonon spectrum where the Debye $\sim \omega^2$ law at low frequency melds into an anomalous excess-mode peak (the boson peak) before entering a quasi-localized regime at higher frequencies dominated by scattering. The microscopic origin of the boson peak has remained e…
ABSTRACT Iron (Fe) is an essential micronutrient for plants as it takes part in major metabolic pathways such as photosynthesis and respiration and is linked to many enzymes that accomplish many other cellular functions (DNA synthesis, nitrogen fixation, hormone production). Fe deficiency reduces crop yields worldwide…
Wolframelektroden in Kurzbogenlampen unterliegen während des Betriebs einer extremen thermischen Belastung. Um die thermische Belastung der Elektroden zu reduzieren und dadurch die Lebensdauer einer solchen Lampe zu erhöhen, werden die Elektroden mit einer geringen Menge \(ThO_{2}\) dotiert. Alternative Dotierungen de…
Novel type of electronic phase transition driven by the electric dipoles of counter anions has been clarified by nuclear magnetic resonance (NMR) investigation.
Esta tesis aborda el estudio teorico de la interaccion de luz con nanomateriales. En primer lugar se desarrolla un modelo que explica las diferencias espectrales entre las secciones eficaces de absorcion, dispersion, y el campo cercano en nanoparticulas metalicas debida a la excitacion de plasmones, cuando estas prese…
This chapter describes how protein structures are obtained experimentally and discusses methods for computing the geometry of protein molecules. There are primarily three experimental techniques for obtaining protein structures namely, X-ray crystallography, solution nuclear magnetic resonance (NMR), and recently free…
Abstract Tumor Treating Fields (TTFields), a clinically active anticancer modality, are based on low intensity intermediate frequency alternating electric fields that exert their cytotoxicity by disrupting mitosis. The present study examines whether concomitant paclitaxel and TTFields have a beneficial impact on ovari…
The heat transfer in semiconducting nanostructures is a current research topic, covering a wide range of applications including self-heating in nanoelectronic devices and energy conversion via thermoelectric effect. The modeling of heat transport at the nanometer scale is complex as the device length is in the same or…
Abstract Chaperonin, heat shock protein 60, plays an important role in the proteostasis of cytosol. Chaperonins are divided into two groups: group I and group II. Group II chaperonins exist in eukaryotes and archaea, and these chaperonins are named CCT/TRiC and Thermosome, respectively. Group II chaperonins have almos…
Significance and Use 3.1 This test method is used to determine the flexural strength of specimens prepared and cured in accordance with Test Methods C42/C42M or Practices C31/C31M or C192/C192M. Results are calculated and reported as the modulus of ruptu
This research examined the evolving microstructure of quasi-static and dynamically loaded fully annealed metastable 301 austenitic stainless steel (SS). Experiments were performed to an interrupted strain value of 20% and to failure using a tension Kolsky bar (1000/s) and an electromechanical load frame (0.001/s). Ele…
In the present research the horizontal solidification of Sn-Zn eutectic alloys (Sn-8.9wt.%Zn) is performed, with two opposite senses of heat extraction. From the process of solidification, the thermal parameters (local solidification time, cooling rates and interphases velocities) and grain sizes from macrostructures…
Abstract. The molecular structure of volatile organic compounds (VOC) determines their oxidation pathway, directly impacting secondary organic aerosol (SOA) formation. This study comprehensively investigates the impact of molecular structure on SOA formation from the photooxidation of twelve different eight to nine ca…
A three dimensional carbon network material of seamless interconnected and hollow tubes, featuring a graphitic structure and an extremely low density has been designed and fabricated in cm3 volumes. The synthesis of this foam like material, named Aerographite, is based on highly-porous three dimensional networks from…
From systematic nuclear magnetic resonance (NMR) measurements on LaFe(As1−xPx)(O1−yFy), Shiota et al. reported that antiferromagnetic spin fluctuations (AFMSFs) are one of the indispensable elements for enhancing Tc, and that the high-energy AFMSFs originating from the three orbitals of dxy and dyz/zx, are related to…
[EN] An integrated methodology incorporating preliminary archaeometric studies, design and performance of conservative and preventive treatments, as well as the design of an expositive support for a Montefortino helmet conserved at the Museum of Requena (Valencia, Spain), is presented. It was a helmet dated back at th…
Le but de la Nano- Opto- Mécanique et Electronic à base de graphène est d'utiliser des membranes de graphène en suspension comme blocs de construction pour aborder le couplage entre l'optique, la mécanique et l'électronique dans ce nouveau matériau. Avec un module d'Young similaire à celui du diamant (1 TPA), le graph…
This chapter focuses on the application of millisecond hydrogen exchange HX (labeling) times to characterize weakly structured regions of proteins and subsecond conformational transitions in protein function. The first millisecond protein HX measurements were made by automated quench-flow pulse labeling and were aimed…
This specification covers deformed and plain low-alloy steel bars in cut lengths or coils for concrete reinforcement intended for applications. Restrictive mechanical properties and chemical composition are required for compatibility with controlled tensile property applications or to enhance weldability. The steel sh…
