An approach utilizing a hot-press to form wrinkle-free monolayer graphene on a Cu thin film using a chemical vapor deposition (CVD) process is introduced. With this method, an extremely flat Cu thin film is obtained even after the high temperature annealing and this allows the formation of wrinkle-free monolayer graphene on top of the flat Cu surface.

Ultrathin tellurium nanowires (TeNWs), as a model material, have been used to study the stability of nanomaterials in aqueous solution through an accelerated oxidation process from the viewpoint of reaction kinetics, leading to a new approach for the design and synthesis of other unique one-dimensional nanostructures by a chemical transformation process using the intermediate nanostructures “captured” during the dynamic oxidation process under different conditions.

An ultrasensitive ultraviolet (UV) detector based on a p-type ZnS nanoribbon (NR)/indium tin oxide (ITO) Schottky barrier diode (SBD) has been fabricated. The device exhibits a pseudo-photovoltaic behavior which can allow the SBD to detect UV light irradiation with incident power of 6 × 10–17 W (~85 photons/s on the NR).

We report a facile colloidal route to synthesize MoSe2 porous microspheres with diameters of 400–600 nm made up of monolayer flakes. The robust 3D MoSe2 porous microspheres exhibit remarkable activity and durability for the electrocatalytic hydrogen evolution reaction (HER) in acid, maintaining a small onset overpotential of ~77 mV and keeping a small overpotential of 100 mV with a current density of 5 mA/cm2 after 1,000 cycles.

A series of perovskite solar cells with 2TPA-n-DP (TPA = 4,4'-((1E, 1'E,3E,3'E)-[1,1'-biphenyl]-4,4'-diylbis(buta-1,3-diene-4, 1-diyl)); DP = N,N-di-p-tolylaniline; n = 1–4) as the hole-transporting material (HTM) have been fabricated. Power conversion efficiencies (PCE) of up to 12.96% have been achieved, comparable to a device with (2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene) (spiro-OMeTAD) as the HTM under similar conditions.

A novel design of all-solid-state, highly flexible, coaxial fiber asymmetric supercapacitors (ASCs) has been developed by wrapping a carbon nanotube/carbon paper electrode on a hierarchically nanostructured nanoporous gold@MnO2 wire. The as-fabricated coaxial fiber ASCs can be reversibly charged/discharged at a high voltage of 1.8 V, delivering a high energy density of 5.4 μW·h·cm–2 and power density of 2,531 μW·cm–2.
