Nickel cobaltite (NiCo2O4) aerogels, synthesized with a chloride-based epoxide-driven sol–gel process, exhibit ultrahigh specific capacitances (1400 F g−1; see figure), excellent reversibility, and outstanding cycle stability, at relatively high mass loading of 0.4 mg cm−2.
Abstract A newly designed water‐stable NH 2 ‐MIL‐88B(Fe Ni)‐metal–organic framework (MOF), in situ grown on the surface of a highly conducting 3D macroporous nickel foam (NF), termed NFN‐MOF/NF, is demonstrated to be efficient bifunctional electrocatalyst for overall water splitting with ultrastability at high current densities. The NFN‐MOF/NF achieves ultralow overpotentials 240 and 87 mV density 10 mA cm −2 oxygen evolution reaction hydrogen reaction, respectively, 1 m KOH. For splitting,...
Vertically grown cadmium sulfide (CdS) nanowire (NW) arrays were prepared using two different processes: hydrothermal and physical vapor deposition (PVD). The NWs obtained from the process composed of alternating hexagonal wurtzite (WZ) cubic zinc blende (ZB) phases with growth direction along WZ ⟨0001⟩ ZB [111]. produced by PVD are single crystalline phase ⟨0001⟩. These vertically CdS NW have been used to converting mechanical energy into electricity following a developed procedure [Z. L....
Mesoporous structures of high specific surface areas and porosities, such as aerogels, are ideal for supercapacitor applications. This idea was successfully demonstrated the first time by taking cobalt oxide aerogels an example. Cobalt excellent supercapacitive properties, including capacitances (the highest ever reported oxides, >600 F/g at a mass loading 1 mg/cm2) onset frequencies, reversibility cycle stability, were synthesized with epoxide addition procedure using nitrate precursor. The...
The necessity for new sources greener and cleaner energy production to replace the existing ones has been increasingly growing in recent years. Of those sources, hydrogen evolution reaction a large potential. In this work, first time, MoSe2 /Mo core-shell 3D-hierarchical nanostructures are created, which derived from Mo through low-temperature plasma-assisted selenization process with controlled shapes grown by glancing angle deposition system.
Abstract Lithium metal (LM) is a promising anode material for next generation lithium ion based electrochemical energy storage devices. Critical issues of unstable solid electrolyte interphases (SEIs) and dendrite growth however still impede its practical applications. Herein, composite gel polymer (GPE), formed through in situ polymerization pentaerythritol tetraacrylate with fumed silica fillers, developed to achieve high performance batteries (LMBs). As evidenced theoretically...
A new single nanowire based nanosensor is demonstrated for illustrating its ultrahigh sensitivity gas sensing. The device composed of a ZnO mounted on Pt electrodes with one end in Ohmic contact and the other Schottky contact. functions as "gate" that controls current flowing through entire system. By tuning barrier height responsive variation surface chemisorbed gases amplification role played by to effect, an 32,000% was achieved using contacted operated reverse bias mode at 275 degrees C...

This work demonstrates triple coupling among semiconducting, piezoelectric, optoelectric properties, which may be useful for designing new optopiezotronic devices.
Monolithic silica aerogels with thermal conductivity as low 0.036 W·(m·K) −1 and porosity high 97% were successfully prepared by ambient pressure drying through a multiple modification approach. This approach may replace the more costly dangerous operation of supercritical drying.

The Schottky contact based photon detection was demonstrated using CdS (visible light responsive), silicon (indirect n-type oxygen-non-adsorbing), and CuO p-type oxygen-adsorbing) nanowire nanosensors. With changing one of the two nanowire-electrode contacts from ohmic to Schottky, sensitivities as high 105% were achieved by nanosensor operated at reverse bias mode −8 V, which 58 times higher than that corresponding device. reset time also significantly reduced. In addition, originally...
