Porous carbon polyhedra (ZnCoNC) were fabricated using Zn-doped, Co-based metal-organic frameworks as precursors. Doping with Zn species reduces the Co nanoparticle size and increases the nitrogen content of the products, endowing the as-prepared ZnCoNC with enhanced ORR and OER electrocatalytic activity in alkaline media, thus making them promising cathode materials for zinc-air batteries.

Hollow carbon nano-onions (CNOs) are preferred precursors for the synthesis of graphene quantum dots (GQDs) with a uniform size distribution, whereas metal encapsulation in the CNO structure is disadvantageous for the same. Furthermore, acid oxidation of hollow CNOs can result in GQDs with a yellow-green hybrid luminescence and long excitation wavelength (λex)-ranged λex-independent photoluminescent (PL) behavior, in which the λex upper limit is 480 nm. This enables sensing and cell imaging under visible light excitation with no need for UV excitation.

A polythiophene-based copolymer (PDVT-10) with a hole mobility up to 8.2 cm2·V−1·s−1 and a highest occupied molecular orbital level of −5.28 eV is used as a hole-transport layer for perovskite solar cells for the first time. The new additive-free hole-transport material exhibits better photovoltaic performance than poly(triarylamine)-based devices and can function as an encapsulation layer for NH3CH3PbI3 to maintain long-term stability.

A homogeneous Ni(OH)2 coating was grown on carbon nanosheets by a facile ion-exchange reaction, via the in situ transformation of MgO/C to Ni(OH)2/C. The obtained Ni(OH)2/C composite exhibits superior performances as an asymmetric supercapacitor, with a large capacity (198 F/g), high energy density (56.7 Wh/kg at 4.0 kW/kg), and excellent cycling stability, with 93% capacity retention after 10,000 cycles.

The band gap of titanium trisulfide is extremely sensitive to the application of uniaxial strain, especially in the facile transport direction. Moreover, for large enough strain (but still within the elastic limit) the nature of the band gap changes from direct to indirect, with strong implications for the potential application of these materials in optical devices.

An innovative 3D sponge-like nanographene (SG) shell is designed and applied on a silicon substrate, resulting in a Si@SG hybrid with unique properties, suitable to overcome the main issues affecting the application of silicon in lithium ion batteries. Electrodes based on the novel Si@SG hybrids achieve excellent electrochemical performance in terms of long-term cycling stability and rate performance at different current densities.

The solvent–cation interaction dominates directional transport of organic solvent in the M-GO membranes by the site-to-site mechanism. The competition between energy consumption by the solvent–cation interaction and energy expenditure by the solvent–epoxy (–hydroxyl) interaction enables the M-GO membranes with the selective permeability to a wide range of solvents.
