Black titania nanotube arrays are prepared for the first time, which exhibit an excellent photoelectrochemical water-splitting performance.
Supercapacitors suffer either from low capacitance for carbon or derivate electrodes poor electrical conductivity and electrochemical stability metal oxide conducting polymer electrodes. Transition nitrides possess fair but superior chemical stability, which may be desirable candidates supercapacitors. Herein, niobium nitride, Nb 4 N 5 , is explored to an excellent capacitive material the first time. An areal of 225.8 mF cm −2 with a reasonable rate capability (60.8% retention 0.5 10 mA )...
Advancing thermoelectric n-type Mg3 Sb2 alloys requires both high carrier concentration offered by effective doping and mobility enabled large grains. Existing research usually involves chalcogen on the anion sites, resultant reaches ≈3 × 1019 cm-3 or below. This is much lower than optimum theoretically predicted, which suggets that further improvements will be possible once a highly efficient dopant found. Yttrium, trivalent dopant, shown to enable concentrations up above ≈1 1020 when it...
Recently, researchers spare no efforts to fabricate desirable vanadium dioxide (VO2) film which provides simultaneously high luminous transmittance and outstanding solar modulation ability, yet progress towards the optimization of one aspect always comes at expense other. Our research devotes finding a reproducible economic solution-processed strategy for fabricating VO2-SiO2 composite films, with aim boosting performance both aspects. Compare VO2 film, an improvement 18.9% (from 29.6%...
Oxygen-deficient black Nb<sub>2</sub>O<sub>5</sub> nanochannels are successfully prepared, and studied as efficient photoanodes for photoelectrochemical water splitting the first time.
The garnet ionic conductor is one of the promising candidate electrolytes for all-solid-state secondary lithium batteries, thanks to its high ion conductivity and good thermal chemical stability. However, microstructure difficult approach because it very sensitive inquisitive electron beam. In this study based on a scanning microscope (SEM), we found that beam expulses out Li6.4La3Zr1.4Ta0.6O12 (LLZTO), expulsed zone expands where stationary could extend penetrate. expulsion metallic was...
To deal with the low conductivity and structural instability of silicon (Si)-based anode, a Ge–Si/C nanofiber (Ge–Si/CNF) composite is fabricated based on different starting reaction potentials for Si Ge lithium excellent Ge. Sucrose innovatively introduced as spinning aid to maintain carbon fiber structure derived from poly(vinyl alcohol) polymer. When Ge–Si/CNFs are investigated anode material lithium-ion batteries, it demonstrates cyclic stability rate capability. Specifically, can still...
Quantitative analyses of the local chemistry amorphous films at grain boundary (GB) were taken on hot isostatically pressed high‐purity Si 3 N 4 doped with various amounts calcium (up to 450 ppm). This work was mainly accomplished by using spatially resolved electron energy‐loss spectroscopy (EELS) in a dedicated scanning transmission microscope. The amount segregation, quantified terms GB excess, saturated bulk‐doping level ∼220 ppm. Extra additives did not stay triple‐point glass pockets,...

High‐resolution transmission electron microscopy observation energy‐loss spectroscopy analysis revealed...
The low powder factor (PF) of polycrystalline oxide perovskites induced by the resistive grain boundaries or known as double Schottky barrier (DSB) greatly restricts their thermoelectric performance in application. Here, a general protocol including (i) and (ii) bulk reduction H2/Ar forming gas is demonstrated to break DSB La Nb codoped SrTiO3. While guarantees high carrier concentration fully stimulating donor doping effect, effectively lowers influencing point defects at boundaries, which...
