Abstract:

Dislocation loop was generated by electron irradiation in nickel aluminum alloy. It is important to know dislocation characteristics obtained from a high energetic electron irradiation. If b is the Burger vector of a dislocation loop and g is the diffraction vector, dislocation loop will appear larger, smaller or disappear for g.b>0, g.b<0 or g.b=0, respectively. Dislocation loop was determined as follows – first, the appearance of dislocation loops is arranged in observation table. Second, based on type of dislocation loop, Burger vector and diffraction vector, appearance of dislocation

An in-situ experiment in an electron microscope is now a well established and useful technique in materials science. In this review recent contributions of in-situ experiments, especially of straining and heating experiments, to materials science will be high-lighted.The earlier works have been reviewed by Saka and Imura.It is believed that an external stress gives rise to an anistropy in the rate at which point defects are absorbed by edge dislocations; this mechanism is considered to explain the irradiation creep.

Abstract:

In this paper, we report on the synchrotron white beam topographic (SWBXT) observation of “hopping” Frank-Read sources in 4H-SiC. A detailed mechanism for this process is presented which involves threading edge dislocations experiencing a double deflection process involving overgrowth by a macrostep (MP) followed by impingement of that macrostep against a step moving in the opposite direction. These processes enable the single-ended Frank-Read sources created by the pinning of the deflected basal plane dislocation segments at the less mobile threading edge dislocation segments to “hop” from on

Abstract:

A model based on the generation and recombination of defect was developed to describe the stability of stacking faults and basal plane dislocation loops in crystals with layered polytype structures. The stability of the defects configuration was analysed for stacking faults surrounded by Shockley and Frank partial dislocation as well as Shockley dislocation dipoles with long range elastic fields. This approach allows the qualitative prediction of defect subsystems in polytype structure in external fields.

Abstract:

Dislocation dynamics has been an intensive research subject in materials science and engineering due to the significant roles it plays in plastic deformation and the hardening of metals, fracture mechanics, and the fabrication of semiconductor thin films. However, a long-standing problem from the three-dimensional dislocation dynamics is that the motion and interaction of dislocation loops heavily depend on the loop-segment sizes, which substantially reduces the accuracy of simulation. We herein propose a new three-dimensional dislocation dynamics model together with its physical background. T

Abstract During transmission electron microscopy (TEM) investigations of Al alloys, defects caused by the electron irradiation can occur. Since the image contrast of these irradiation defects is similar to that of early stages of precipitates, care is needed to avoid confusion. In the present paper the formation and the coarsening of radiation damage defects were studied by in situ TEM in both, pure Al and Al alloys.

Here, molecular dynamics (MD) simulations have been used to investigate the formation of atomic displacement cascade in γ-iron for energies of the primary knock-on atom (PKA) up to 40 keV at 300 K. The number of Frenkel pairs increased sharply until a peak value was reached, which occurred at a time in the range of 0.1-2 ps. After that, a number of defects gradually decreased and became stabilized. Compared with α-iron, there was le

Silicon carbide (SiC) is a promising material used in the advanced semiconductor industry. Fabricating SiC-on-insulator via H implantation is a good method. He and H co-implantation into Si can efficiently enhance exfoliation efficiency compared to only H implantation. In this study, 6H-SiC single crystals were implanted with He+ and H2+ dual beams at room temperature, followed by annealing at 1100 °C for 15 min, and irradiations with 60 keV He ions with a fluence of 1.5 × 1016 ions/cm−2 or 5.0 × 1016 ions/cm−2 and 100 keV H2+ ions with a fluence of 5 × 1016 ions/cm−2 were carried out.

Abstract:

Studies of regional ischemia in the canine left ventricle (LV) have shown augmented systolic segmental shortening in nonischemic regions. To characterize these responses in the right ventricle (RV), acute occlusions of the right coronary artery (RCAO) were produced in anesthetized pigs. Orthogonal pairs of ultrasonic segment-length crystals were implanted in the mid-RV free wall (ischemic region) and in the outflow tract (nonischemic region). RV pressure-area work loops were generated during inferior vena caval occlusions, and both slope (M) of the preload recruitable stroke work relationship

Abstract:

AbstractThis review offers a critical-care perspective on the pathophysiology, monitoring, and management of acute heart failure syndromes in children. An in-depth understanding of the cardiovascular physiological disturbances in this population of patients is essential to correctly interpret clinical signs, symptoms and monitoring data, and to implement appropriate therapies. In this regard, the myocardial force–velocity relationship, the Frank–Starling mechanism, and pressure–volume loops are discussed. A variety of monitoring modalities are used to provide insight into the haemodynamic stat

Abstract:

Frank Herbert’s Dune novels are suffused with Zen concepts that support his belief in ecology in two major ways. Firstly, Herbert’s reflections on the novels in key interviews make explicit that he consciously uses the trope of Zen philosophy to explore and prosecute the case for environmentalism and ecology. And secondly, the series is replete with structural elements and literary motifs that are a homage to core Zen teachings and reinforce the ecological themes of the work. Thematic explorations of the importance of balance between the spiritual and physical elements of human life are repres

Abstract:

Multicomponent alloys possessing nanocrystalline structure, often alluded to as Cantor alloys or high entropy alloys (HEAs), continue to attract the great attention of the research community. It has been suggested that about 64 elements in the periodic table can be mixed in various compositions to synthesize as many as ∼108 different types of HEA alloys. Nanomechanics of HEAs combining experimental and atomic simulations are rather scarce in the literature, which was a major motivation behind this work. In this spirit, a novel high-entropy alloy (Ni25Cu18.75Fe25Co25Al6.25) was synthesized usin

Abstract:

Abstract Many factors complicate therapeutic strategies for glioblastoma (GBM), including the existence of the blood brain barrier and a heterogenous population of difficult to treat glioma stem cells. Innovative strategies targeting novel pathways alone or in combination are needed for sustainable therapeutic improvements. The MAPK pathway has been implicated in many cancers. MAPK interacting kinases (MNK1 and MNK2) are downstream of MAPKs and phosphorylate the eukaryotic translation initiation factor 4E (eIF4E), a protein involved in translation of oncogenic mRNAs.

Abstract:

The poetry of Frank O'Hara (1926–66) takes place in the routes of New York City, both above and below the ground. This essay looks at the characteristics of his poetic lines, and some of the ways they invest themselves in each other, interacting complexly through rhymes and line breaks that we may struggle to negotiate. Then, broadening outwards to consider urban topographies and the experience of inhabiting the avenues of Manhattan, it discusses how the lines of a poem might relate to the lines of a subway system or street grid, and considers how O'Hara's poetry opens our attention, and our g
