The effect of the binding of pyridine ligands to pentafluorophenyl copper, [C 6 F 5 Cu] 4 ( 1 ), on structural features and photophysical properties has been investigated through a combined multinuclear NMR, X-ray crystallography, and photoluminescence study. Reaction of 1 with 2 equiv of pyridine yields a novel pyrid…
Geomaterials are materials inspired by geological systems originating from the billion years long history of the Earth. This article reviews three important classes of geomaterials. The first one is smectites-layered silicates with a cation-exchange capacity. Smectites are useful for removing pollutants and as interca…
We demonstrate that the use of the direct, heat source/sink method for thermal conductivity determination via molecular dynamics simulation leads to diverging thermal conductivity with increasing simulation cell length when the cross section of the cell is kept constant. A phonon transport theory based analysis shows…
SOFC-based micro-CHP system as an example of efficient power generation unit Microscale combined heat and power (CHP) unit based on solid oxide fuel cells (SOFC) for distributed generation was analyzed. Operation principle is provided, and the technology development in recent years is briefly discussed. System baselin…
The main aim of this study is to compare the experimentally observed tensile properties of banana/epoxy composite with those obtained using various theories of reinforcement. Models used for the comparison are Hirsch, Halpin–Tsai, Nielson, Bowyer and Bader’s, and Modified Rule of Mixture. Further, the effect of fiber…
Abstract The dodecagonal quasiperiodic order is rather rare in the material world, but has been observed in various systems from alloys to aggregates of cylindrical polymers and in a wide range of dimensions. They exhibit uniaxial 12‐fold diffraction symmetry, and have common structural properties originating from the…
The concept of a phononic crystal can in principle be realized at the nanoscale whenever the conditions for coherent phonon transport exist. Under such conditions, the dispersion characteristics of both the constitutive material lattice (defined by a primitive cell) and the phononic crystal lattice (defined by a super…
Plate‐like ZrB 2 grains were synthesized at 1550°C by in situ solid/liquid reaction using Zr and B powders mixed with transition metal ( Mo , Nb , Ti , or W ) and Si powder. The preferred growth direction of plate grains was along a ‐ or b ‐axis depending on the initial content of transition metal and silicon in the m…
Inclined-plane tests of silicone-rubber samples prepared with textured patterns of hemispherical protuberances are described. These are compared with the results obtained for conventional non-textured plane-surface samples of the same material. A remarkable improvement is achieved by such texturing: a material which n…
This paper summarizes a multi-disciplinary effort to realize the high expectations of the use of carbon nanotube (CNT) as a material for highly energy-efficient future digital systems. Today CNTs are grown on full wafers, highly aligned in one direction, and subsequently transferred to a target substrate multiple time…
The latest discovery of a new iron-chalcogenide superconductor A x Fe 2− y Se 2 ( A =K, Cs, Rb, and Tl, etc.) has attracted much attention due to a number of its unique characteristics, such as the possible insulating state of the parent compound, the existence of Fe-vacancy and its ordering, a new form of magnetic st…
An interaction of deuterium plasma with seeding species with a material is, in particular, an issue for medium- and high- Z plasma-facing materials for fusion devices to reduce the power load in front of material surfaces. In this paper, we investigated the influence of seeding of nitrogen (N) into deuterium plasma on…
Piroxicam is a nonsteroidal anti-inflammatory drug with low aqueous solubility which exhibits polymorphism. The present study was carried out to develop polymorphs of piroxicam with enhanced solubility and dissolution rate by the crystal modification technique using different solvent mixtures prepared with PEG 4000 an…
1 μm thick Si solar cells based on nanocone grating (NCG) with height of 100-800 nm and period of 100, 500, and 800 nm are numerically investigated through reflectivities, absorption enhancement factors, absorption spectra, optical generation rates, ultimate efficiencies, and diffraction angles. Compared with the plan…
A new cell-state metric is proposed for multilevel phase-change memory (PCM) that is more representative of the fundamental programmed entity, i.e., the amorphous/crystalline phase configuration in the PCM cell. This metric exhibits improved performance in terms of drift and better sensing resolution of cell states wi…
In this work, the focus is on the thermal shock analysis of fine- and ultra-fine-grained tungsten-based materials doped with 0.5–1.1 wt% TiC that showed in previous studies improved ductility at low temperatures and also performed well when exposed to neutrons and ions (H/He). Herein, the resistance of the material to…
Tungsten is foreseen as the plasma-facing component material for baffles, the dome and strike-point area in the ITER divertor. Quantification of the W source, which is connected with the components lifetime and W plasma concentration, is one of the outstanding issues in the qualification process. A dedicated experimen…
We present the effects of cross talk in graphene nanoribbon (GNR) interconnects for 16 nm technology node. This is the first time that the cross talk analysis is presented in GNR interconnects. The electrical equivalent model is used to derive the electrical circuit parameters for GNR interconnects and cross talk anal…
Five new hybrid compounds constructed from polyoxometalates and transition metal coordination complexes with lower positive charge: [PW11CuO39][Cu(bpy)2]5 (1), [BW12O40][Cu(bpy)2]5 (2) [BW12O40][Cu(Phen)2]3[Cu(Phen)(H2O)]2·2H2O (3), [SiW12O40][Cu(bpy)2]4 (4) and [PW12O40][Cu(bpy)2]4 (5) have been prepared and characte…
Tungsten is a candidate material for the divertor and for first wall armor of future thermonuclear fusion reactors (ITER and DEMO). In such irradiation conditions, it is well known that the microstructure, and as a result the properties of the materials, will evolve. In this perspective, the fate of irradiation-induce…
