Chemoselective photodeoxidization of graphene oxide using sterically hindered amines as catalyst : synthesis and applications
We report a green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation catalyzed with 2,2,6,6-tetramethyl-4-piperidinol. While the sp2-hybridized oxygen functional groups ...
Cadmium telluride nanocrystals : synthesis, growth mode and effect of reaction temperature on crystal structures
A series of cadmium telluride (CdTe) nanocrystals were synthesized by a modified organometallic synthesis method at various reaction temperatures ranging from 130 to 250°C. In this method, octadecylamine (ODA) was introduced ...
A rectifying diode with hysteresis effect from an electroactive hybrid of carbazole-functionalized polystyrene with CdTe nanocrystals via electrostatic interaction
One of the strategies to tune current-voltage behaviors in organic diodes is to combine field-induced charge transfer processes with schottky barrier. According to this principle, a rectifying diode with hysteresis effect ...
Preparation of MoS2-polyvinylpyrrolidone nanocomposites for flexible nonvolatile rewritable memory devices with reduced graphene oxide electrodes
A facile method for exfoliation and dispersion of molybdenum disulfide (MoS2) with the aid of polyvinylpyrrolidone (PVP) is proposed. The resultant PVP-coated MoS2 nanosheets, i.e., MoS2-PVP nanocomposites, are well dispersed ...
Polyphenylene dendrimer-templated in situ construction of inorganic–organic hybrid rice-shaped architectures
A novel dendrimer-templating method for the synthesis of CuO nanoparticles and the in situ construction of ordered inorganic–organic CuO–G2Td(COOH)16rice-shaped architectures (RSAs) with analogous monocrystalline structures ...
Two-dimensional CuSe nanosheets with microscale lateral size : synthesis and template-assisted phase transformation
Semiconducting nanosheets with microscale lateral size are attractive building blocks for the fabrication of electronic and optoelectronic devices. The phase-controlled chemical synthesis of semiconducting nanosheets is ...
3D graphene foam as a monolithic and macroporous carbon electrode for electrochemical sensing
Graphene, a single-atom-thick monolayer of sp2 carbon atoms perfectly arranged in a honeycomb lattice, is an emerging sensing material because of its extraordinary properties, such as exceptionally high specific surface ...
All-carbon electronic devices fabricated by directly grown single-walled carbon nanotubes on reduced graphene oxide electrodes
A simple method for fabrication of all carbon CNT-rGO devices was developed, where the individual long-aligned SWCNT directly grew by CVD to connect with rGO electrodes scratched by non-metal objects.
Fabrication of flexible, all-reduced graphene oxide non-volatile memory devices
A flexible, all reduced graphene oxide non-volatile memory device, with lightly reduced GO as an active layer and highly reduced GO as both top and bottom electrodes, is fabricated by a full-solution process and its ...
Coating two-dimensional nanomaterials with metal-organic frameworks
We demonstrate the coating of various 2D nanomaterials including MoS2 nanosheets, graphene oxide (GO), and reduced graphene oxide (rGO) with zeolitic imidazolate frameworks (i.e., ZIF-8) via a facile procedure. Additionally, ...
