Abstract:

ABSTRACTSuperconducting NMR pickup coils have to have a low surface resistance (Rs) under a high magnetic field. One way of reducing the Rs of superconducting thin films is adding artificial pins to the films. We examined the hetero-epitaxial growth of MgB2and YBCO thin films on decorated sapphire and MgO substrates while using nano-wires and nano-particles to add pins to the films.We used ZnO nano-wire to add artificial grain boundary pins to MgB2 films. The tilted c-plane sapphire substrate with nano-step edges was used for these substrates. The terrace width with one lattice step edge can b

Abstract:

Recently, we discovered the horizontally-aligned growth of single-walled carbon nanotubes (SWCNTs) on R- and A-plane sapphire substrates, which we call "atomic arrangement-programmed growth (AAP growth)." This is a unique method because the growth direction of SWCNTs is determined by the crystallographic direction of the sapphire surface. In this paper, we report on the characterization of the aligned SWCNTs by polarized Raman and electron transport measurements, and on the effect of the step/terrace structure formed on sapphire surface. These results may open up a possibility of creating the

Abstract:

Abstract Traditionally, the color grading of sapphire is mainly based on the naked eye judgment of the appraiser. This judgment standard is not clear enough, and the judgment result has a greater subjective influence, which affects the accuracy of the classification. In this study, the GEM-3000 ultraviolet-visible spectrophotometer was selected, and the color features of 180 sapphire samples were extracted and classified using the CIE1976 color space of the device. The Kmeans algorithm was used to cluster analysis of 140 samples, and the separability of the color space features of different co

Abstract:

Sapphire (α–Al2O3) and Al were joined by means of the surface activated bonding (SAB) method in an ultrahigh vacuum at room temperature. Tensile tests have shown that failure occurred not along the interface but inside the Al bulk near the interface. High resolution transmission electron microscopy has revealed the formation of a direct interface between Al and sapphire, indicating the possibility to artificially fabricate an atomically direct interface of dissimilar materials at room temperature. However, an intermediate layer was partially observed, which might be attributed to the effect of

Abstract Metasurfaces with ultrathin artificial structures have attracted much attention because of their unprecedented capability in light manipulations. The recent development of metasurfaces with controllable responses opens up new opportunities in various applications. Moreover, metasurfaces composed of twisted chiral structures can generate asymmetric responses for opposite incidence, leading to more degrees of freedom in wave detections and controls. However, most past studies had focused on the amplitude responses, not to mention using bi-directional phase responses, in the characteriza

Abstract:

<strong>Abstract</strong> The possibility of making precious stones from radioactive waste is being considered. Vitrified and cemented radioactive waste (RW) is considered as an artificial rock belonging to aluminosilicates and calcites. Two methods are proposed for the manufacture of radioactive gemstones from RW and their subsequent storage with the possibility of sale, resale, inheritance, and so on. That is, RW is considered as real estate in which capital can be invested. After decontamination in hundreds and thousands of years, it will be of scientific, historical, jewelry interest.

Abstract:

AbstractMoiré lattice in artificially stacked monolayers of two-dimensional (2D) materials effectively modulates the electronic structures of materials, which is widely highlighted. Formation of the electronic Moiré superlattice promises the prospect of uniformity among different moiré cells across the lattice, enabling a new platform for novel properties, such as unconventional superconductivity, and scalable quantum emitters. Recently, epitaxial growth of the monolayer transition metal dichalcogenide (TMD) is achieved on the sapphire substrate by chemical vapor deposition (CVD) to realize sc

Abstract:

It is important to understand Martian samples and their exact habitats, including extreme conditions, to improve future exploration of Mars. The Mars laboratory of Eco Astronomy Inc., represented by the Department of Research and Innovation’s Advances in Multidisciplinary Studies Unit, has developed a standard Mars Regolith Simulant called “HAYA"—Eco Astronomy Artificial Regolith of Mars | J-Collection. This experiment is based on APXS data from Meridiani Planum, which was pre-analyzed via CheMin on NASA’s Mars Curiosity Rover. To develop the Martian soil simulant, serpentine soil from Ussango

Abstract:

AbstractBasic studies on ultrafast laser ablation processes are important for expanding their utility. In particular, understanding the ablated morphology in relation to the incident pulse is critical for micromachining, and an important benchmark for simulations. However, current morphological analyses rely on vast simplifications of experimental conditions, such as a singular fluence value to reduce a unique beam profile, or the maximum crater depth or diameter to describe the ablated morphology. Here, we develop a morphology analysis method in which we take the full two-dimensional informat

Abstract:

AbstractDevelopment of artificial opto‐electronic synaptic devices plays a crucial role for the practical implementation of energy‐efficient, parallel processing of human brain. In this article, two terminal inter‐digitated devices are fabricated on Gallium oxide (Ga2O3) thin films grown on sapphire substrates by pulsed laser deposition (PLD) technique to study its ability to mimic biological synaptic behaviors. The layers are found to exhibit long persistent photo‐conductivity (PPC) effect, which is identified to be the key parameter to replicate the behavior of biological synapses. Channel r

Abstract:

AbstractGlobal food supply chains are unprepared for the increasing number and severity of the expected environmental, social and economic shocks in the coming years. The price-setting process of commodities is directly impacted by such shocks, influencing consumer behavior regarding food choice and consumption. Both the market and advances in precision agriculture drive increased production and consumption. However, there has been a lack of consideration of how consumer behavior could be harnessed to mitigate such shocks through decreased consumption and reduced waste. The SAPPhIRE model of c

Abstract:

Local low-temperature impact on biological tissues, depending on the temperature reached, can lead to destructive, preserving or therapeutic effects. The article describes the principle of a unified approach for the transition from mass recommendations for the dosing of local low-temperature exposure to personalized. It is proposed to divide the exposure process into three stages: planning, provision and control, analysis of compliance with the planned and received dose. Examples of solving the problems of heat transfer in cryosurgery and cryopreservation are given for a possible improvement o
