Apart from Li
Hybridization of nanostructured cobalt oxides with carbon nanotubes (CNTs) is considered to be an operative approach harvest high-performance anode material for lithium-ion batteries (LIBs). On the other hand, there are numerous related works, most which adopted a "post-combination" strategy, not only complicated but also ecologically unpromising using toxic acid surface modification CNTs. Herein, we productively fabricate Co@Co3O4/CNTs nanocomposite excellent conductivity through arc...
Li4Ti5O12 anode can operate at extraordinarily high rates and for a very long time, but it suffers from relatively low capacity. This has motivated much research on Nb2O5 as an alternative. In this work, we present scalable chemical processing strategy that maintains the size morphology of nano-crystal precursor systematically reconstitutes unit cell composition, to build defect-rich porous orthorhombic Nb2O5-x with high-rate capacity many times those commercial anodes. The procedure...
Co@Co9S8 nanochains with core-shell structures are prepared by a direct-current arc-discharge technique and followed sulfurization at 200 °C. The nanochains, which consist of uniform nanospheres connecting each other, can range up to several micrometers. thickness Co9S8 shell be changed regulating the time. In this heterostructure Co@Co9S8, Co function as conductive network inject electrons into Co9S8, manipulates work makes it more apposite for catalysis. density functional theory...
Electrodiffusion plays a crucial role in modulating ion channel conductivity and neural firing dynamics within the nervous system. However, its influence on function remains underexplored. In this work, we introduce novel Gauss-Nernst-Planck (GNP) approach to investigate how electrodiffusive rectification activity. For first time, demonstrate that membrane is determined by both permeability harmonic mean of intramembrane concentration, bridging gap between permeability-based...
Semantic segmentation in urban scenes is widely used applications of intelligent transportation systems (ITS). In scenes, thermal infrared (TIR) images can be captured weak illumination conditions or the presence obscuration (e.g., light fog, smoke). Therefore, TIR have great potential to endow automated vehicles assist navigation systems. However, imaging blurry and low-contrast due absorption by atmospheric gases heat transfer effect. Hence, semantic has rarely been explored even though it...
Single-atom catalysts with unique electronic structures are drawing increasing attention as compared nano-catalysts. However, subnano-catalysts, falling between the two categories, may match demands of catalytic reactions better due to their tunable structure, but they have rarely been studied. Here, we report a subnano-ruthenium species anchored on nano-SnO2 ([email protected]2). Although rutile SnO2 and RuO2 isostructural tend form spinodal structure in bulk materials, [email protected]2...
Using a three-dimensional classical ensemble model, nonsequential double ionization (NSDI) of Ar atoms by counter-rotating two-color elliptical polarization (TCEP) fields is investigated.
Nonsequential double ionization (NSDI) of atoms driven by parallel-polarized two-color (PPTC) fields composed two equal-intensity multiple-cycle laser pulses is investigated using a three-dimensional classical ensemble model. The ion momentum distribution shows pronounced asymmetry and strongly depends on the relative phase pulses. distributions exhibit double- or not yet observed triple-hump structure, depending More interestingly, three peaks correspond to first-returning recollision,...
Nonsequential double ionization (NSDI) of Argon atoms by counter-rotating two-color elliptically polarized (TCEP) fields is investigated with a three-dimensional classical ensemble model. Different from circularly fields, the combined electric field in TCEP pulses has no symmetry and ionized electron mainly returns to parent ion one direction. Thus momentum distributions show strong asymmetry. Numerical results increase relative phase between two elliptical return angle travelling electron,...
Hexavalent chromium [Cr(VI)] is carcinogenic and mutagenic even at very low concentrations, yet there are still few effective methods to remove Cr(VI) an ultralow level (<10 ppb). Herein, highly hydroxylated porous nanozirconia (nano-ZrO2) prepared through a unique top-down microetching method, which simulates the formation of "Karst Landform" in nature. Specifically, BaZrO3 utilized as precursor be etched form ZrO2, while particle shape maintained spite removal Ba atoms. X-ray photoelectron...
Poly(lactic acid) (PLA)/starch/montmorillonite (MMT) biodegradable blends were prepared in a twin-screw extruder. The effect of MMT content on the mechanical and thermal properties was studied. microstructure composites observed by wide-angle X-ray diffraction transmission electron microscopy, results showed that there stacked intercalated-and-flocculated structure blends. PLA/starch with had lower crystallisation temperature (T c ) than without MMT. This means made PLA easier. melting (Tm)...
Fuzzy c-means (FCM) is a popular clustering method for image segmentation. However, FCM has difficulties in handling artifacts brain magnetic resonance imaging (MRI), especially when it comes to bias field and noise. We propose novel multiple-surface-approximation-based with interval membership simultaneous correction segmentation of Brain MRI. First, multiple surface representation embedded into estimate correct field. Then memberships the improved are extended intervals. After extension,...
The motion errors of hydrostatic lead screws can be smaller than the pitch due to averaging effect oil films, which is so-called on (AEPE). This paper investigates factors influencing AEPE under low speeds and a constant external load. An equivalent model with continuous helical recesses established, axial nut are obtained by combining dichotomy finite difference methods. results show that (a) caused screw have additivity, little influence errors, (b) when only has cumulative equal average...
