Flower-like CdSe architectures composed of ultrathin nanosheets were prepared via a facile solvothermal method. A relationship was established between the solvothermal temperature and the product structure, and thus the photocatalytic activity. When compared with well-studied CdSe quantum dots, the ultrathin nanosheet assemblies exhibited a better photocatalytic H2 evolution activity under visi...

Mechanical stress is demonstrated in the fabrication process of nanosheet FETs. In particular, unwanted mechanical instability stemming from gravity during channel-release covered detail by aid 3-D simulations. The simulation results show physical weakness suspended nanosheets and impact thickness. Inner spacer engineering based on geometry elastic property are suggested for better stability. f...

The viscoelasticity of boron nitride nanosheet (BNNS) aerogel has been observed and investigated. It is found that the BNNS aerogel has a high damping ratio (0.2), while it exhibits lightweight and negligible temperature dependence below 180 °C. The creep behavior of the BNNS aerogel markedly demonstrates its strain dependence on stress magnitude and temperature, and can be well simulated by th...

Quantum dot (TiO2) self-decorated and defect-free anatase nanosheets were fabricated by a long-time hydrothermal strategy and subsequent defect healing. Such decoration provides a new and effective charge transfer pathway over the nanosheet surface, leading to remarkably high photoactivity.

Large-size single crystalline nanosheets of 9,10-bis(phenylethynyl)-anthracene were prepared by a facile solution process and were fully characterized. The prototype photodetector was then fabricated on the basis of a single nanosheet and exhibited superior performance with the largest photoresponse ratio up to ca. 10(5). Moreover, the nanosheets show obvious light emission anisotropy.

Highly sensitive hydrogen detection at room temperature can be realized by employing solution-processed MoS2 nanosheet-Pd nanoparticle composite. A MoS2-Pd composite exhibits greater sensing performance than its graphene counterpart, indicating that solvent exfoliated MoS2 holds great promise for inexpensive and scalable fabrication of highly sensitive chemical sensors.

Here we demonstrate the in situ formation of ultra-small gold nanoparticles (<2 nm) finely dispersed on a binary solid carrier, i.e. a mesoporous SiO2 coated graphene oxide (GO) nanosheet. The as-synthesized Au-SiO2-GO composite has shown high catalytic activity and reusability for chemical reactions under mild conditions.

Morphological selection of the self-assembled nanostructure of zwitterionic porphyrins between nanorod and nanosheet by the small displacement of the peripheral anionic position is demonstrated based on the J-aggregates of zwitterionic porphyrin isomers, meso-tetrakis(5-sulfonatothienyl)porphyrin diacid and meso-tetrakis(4-sulfonatothienyl)porphyrin diacid.

We report one dimensional (1D) MoS2 nanosheet/porous TiO2 nanowire hybrid nanostructures synthesized by a simple hydrothermal method, leading to an enhanced specific surface area (66 m(2) g(-1)). These 1D hybrid nanostructures as co-catalysts exhibit high activity in visible light photocatalytic hydrogen evolution reaction (HER) with an enhanced hydrogen generation rate of 16.7 mmol h(-1) g(-1).

We report a facile approach to prepare MoS2 nanosheet coated TiO2 nanobelts. The TiO2@MoS2 structure exhibits a reversible capacity of 710 mA h g(-1) at 100 mA g(-1) after 100 cycles with highly stable capacity retention, and bears good rate capability with a reversible capacity of 417 mA h g(-1) at 1000 mA g(-1).
