Lithium-metal anodes are promising electrodes for fabricating high-capacity all-solid-state batteries; however, lithium dendrite growth during charging limits their applicability. One method to suppress is insert a carbon interlayer between the solid electrolyte and lithium-metal anode. There many potential approaches inserting interlayer. The optimal conditions suppressing ensuring uniform deposition have not yet been established. This study employs X-ray computed tomography investigate...
We determined the electrical resistivity of liquid Fe to 135 GPa and 6680 K using a four-probe method in diamond-anvil cell combined with two novel techniques: (i) enclosing molten sapphire capsule, (ii) millisecond time-resolved simultaneous measurements resistance, x-ray diffraction, temperature instantaneously melted Fe. Our results show minimal dependence its anomalous decrease around 50 GPa, likely associated gradual magnetic transition, both agreement previous ab initio...
Three-dimensional measuring method of the material distribution an all-solid-state lithium-ion battery (ASSLiB) cathode, by synchrotron radiation high-resolution X-ray computational tomography (nanotomography, nano-CT) and deep learning is proposed in this study. The cathode ASSLiB comprised materials with high absorption coefficients, such as LiCoO2 LiNi0.5Co0.2Mn0.3O2. Such coefficients imparted difficulties obtaining a high-resolution, high-contrast image identifying conventional CT value...
High-performance all-solid-state lithium-ion batteries require observation, control, and optimization of the electrode structure. X-ray computational tomography (CT) is an effective nondestructive method for observing structure in three dimensions. However, limited availability synchrotron radiation CT, which offers high-resolution imaging with a high signal-to-noise ratio, makes it difficult to conduct experiments restricts use CT battery development. Conversely, laboratory systems are...
Several studies have suggested that the endocannabinoid system plays significant roles in vulnerability to psychiatric disorders including drug abuse. To examine possible association of CNR1 and CNR2 genes, which encode cannabinoid receptors CB1 CB2, with methamphetamine dependence, we investigated three single nucleotide polymorphisms (SNPs) (rs806379, rs1535255, rs2023239) intron 2 gene a nonsynonymous SNP, Q63R, gene. The study samples consisted 223 patients dependence 292 age- sex-...
High-pressure in situ X-ray computational tomography measurements of sulfide solid electrolyte were conducted to elucidate the behavior a single particle. Chlorine Li6PS5Cl was replaced by iodine obtain high-contrast measurements, and particle under high pressure successfully visualized. The experimental results statistically analyzed extract generalized show that pressurization increased contact area sphericity suppressed voids between within particles, thereby enhancing ionic conductivity.
At present, it would be desirable to improve the C-rate values of bulk-type all-solid-state lithium-ion batteries by optimizing electrode structures. Although simulations are an effective means determining optimal structures, a high degree accuracy is required. The present study demonstrates pseudo-two-dimensional (P2D) method simulating cathodes providing improved along with low computational cost and based on actual three-dimensional This incorporates volume fraction tortuosity solid...
Zinc-air batteries are anticipated to be next-generation energy storage devices because of their high capacities compared with conventional secondary batteries. However, the growth zinc dendrites and electrolyte decomposition can compromise battery performance. To solve those problems, a thorough understanding electrode behavior is paramount. Therefore, this study employs operando X-ray transmission imaging observe during charging discharging, aiming elucidate influence on Operando...
Several lines of evidence implicate serotonergic dysfunction in diverse psychiatric disorders including anxiety, depression, and drug abuse. Mice with a knock-out the 5HT1b receptor gene (HTR1B) displayed increased locomotor response to cocaine elevated motivation self-administer alcohol. Previous genetic studies showed significant associations HTR1B alcohol dependence substance abuse, but were followed by inconsistent results. We examined case-control association study...
Bacterial infection results in the production of inflammatory mediators and may be involved pathogenesis sepsis and/or systemic response syndrome. The effect lipopolysaccharide (LPS), a major component outer surface Gram-negative bacteria, Staphylococcal enterotoxin B (SEB), superantigen Gram-positive on cytokine peripheral blood mononuclear cells (PBMCs) was examined. LPS significantly increased proinflammatory anti-inflammatory cytokines, SEB enhanced helper T lymphocyte type cytokines....
Interleukin (IL) 18, a powerful inducer of the immunoregulatory cytokine interferon-gamma (IFN-gamma), presents upstream activation cascade in inflammatory response. The anti-inflammatory properties steroids permit their use various conditions, although effects are transient and pathological states not fully relieved by short-term steroidal use. We examined effect lipopolysaccharide (LPS)/IL-2 on human peripheral blood mononuclear cells (PBMCs). also LPS/IL-2-induced production PBMCs taken...
In order to study the properties of hot nuclei, neutrons emitted in $^{40}\mathrm{Ar}$+Ni, $^{92}\mathrm{Mo}$, $^{122}\mathrm{Sn}$ reactions at E/A=26 MeV were measured coincidence with fusion residues. The neutron spectra obtained for different residue velocities analyzed moving source model. are well reproduced two sources; one corresponds preequilibrium emission and other decay nuclei. extracted multiplicity initial temperature nuclei indicate formation thermally equilibrated excitation...
The regulator of G-protein signaling (RGS) modulates the functioning heterotrimeric G protein. RGS9-2 is highly expressed in striatum and plays a role modulating dopaminergic receptor-mediated cascades. Previous studies suggested that RGS9 gene might contribute to susceptibility psychotic diseases. Therefore, we investigated association between two related dopamine psychoses, schizophrenia methamphetamine use disorders. subjects comprised 487 patients 464 age- sex-matched healthy controls...
In a high performance all-solid-state lithium-ion battery (ASSLiB), should be smoothly transported to minimize overpotential. Nanoscale pores in the ASSLiB can inhibit ionic transportation; therefore, pore structure measured and nanoscale prevented for batteries. this study, laboratory-scale ultra-small-angle X-ray scattering (USAXS) measurements are proposed evaluate ASSLiBs. The results with USAXS validated by comparing them synchrotron radiation (SR) nanotomography data. volumetric...
Experimental studies have demonstrated that not only dopaminergic signaling but also glutamatergic/NMDA receptor play indispensable roles in the development of methamphetamine psychosis. Our recent genetic provided evidence variants glutamate-related genes such as DTNBP1, GLYT1, and G72, which are involved glutamate release regulation co-agonists for NMDA receptors, conferred susceptibility to Serine racemase converts l-serine d-serine, is an endogenous co-agonist receptors. Three single...
