TL;DR: This tutorial review deals with representative contributions in the construction and the structural characteristics of CD-based supramolecular assemblies as well as their interactions with biologically important substrates.
Abstract: Cyclodextrins (CDs) are a class of cyclic oligosaccharides with six to eight D-glucose units linked by α-1,4-glucose bonds, and their capability of forming stable complexes with various organic/inorganic/biological molecules and ions makes them attractive as building blocks for the construction of nano-scale supramolecular systems. This tutorial review deals with representative contributions in the construction and the structural characteristics of CD-based supramolecular assemblies as well as their interactions with biologically important substrates. This review is addressed to students and researchers interested in supramolecular chemistry, biochemistry and nanotechnology.

TL;DR: ZMoS2NRs have a remarkably enhanced binding interaction with Li without sacrificing the Li mobility, and thus are promising as cathode materials of Li-ion batteries with a high power density and fast charge/discharge rates.
Abstract: By means of density functional theory computations, we systematically investigated the adsorption and diffusion of Li on the 2-D MoS2 nanosheets and 1-D zigzag MoS2 nanoribbons (ZMoS2NRs), in comparison with MoS2 bulk. Although the Li mobility can be significantly facilitated in MoS2 nanosheets, their decreased Li binding energies make them less attractive for cathode applications. Because of the presence of unique edge states, ZMoS2NRs have a remarkably enhanced binding interaction with Li without sacrificing the Li mobility, and thus are promising as cathode materials of Li-ion batteries with a high power density and fast charge/discharge rates.

TL;DR: In this paper, 3D hierarchically porous ZnO architectures were synthesized via an amino acid-assisted biomimetic hydrothermal method combined with subsequent calcination, and they were further employed as a support to load Au nanoparticles to construct hybrid nanomaterials for chemical gas sensors.
Abstract: Three-dimensional (3D) hierarchically porous nanostructures with controlled morphology and dimensionality represent one kind of important material and have received enormous attention for a series of applications. In this work, 3D hierarchically porous ZnO architectures were synthesized via an amino acid-assisted biomimetic hydrothermal method combined with subsequent calcination. First a basic zinc carbonate (BZC) precursor with a lamellar spherical morphology assembled by interconnected nanosheets was synthesized. By subsequent calcination, the as-obtained BZC precursor can be facilely transformed into porous ZnO with a large surface area of 193.7 m2/g, while maintaining its 3D hierarchical morphology. The 3D hierarchically porous ZnO superstructures are further employed as a support to load Au nanoparticles (AuNPs) to construct hybrid nanomaterials for chemical gas sensors. The AuNP-functionalized 3D hierarchically porous ZnO nanomaterials, combining the high surface accessibility of porous materials and catalytic activity of small AuNPs, demonstrated excellent sensor properties in terms of higher sensitivity and very fast response. Furthermore, it is expected this AuNP-functionalized 3D hierarchically porous nanostructure may provide a new pathway to develop advanced nanomaterials for applications like gas sensors, low temperature CO oxidation and photocatalysis.

TL;DR: Imaging of HeLa cells and HepG2 cells, a human cervical cancer cell line, was observed with high resolution using N-Cdots as a probe and validates their use in imaging applications and their multicolor property in the living cell system.
Abstract: Carbon dots (Cdots) are an important probe for imaging and sensing applications because of their fluorescence property, good biocompatibility, and low toxicity. However, complex procedures and strong acid treatment are often required and Cdots suffer from low photoluminescence (PL) emission. Herein, a facile and general strategy using carbonization of precursors and then extraction with solvents is proposed for the preparation of nitrogen-doped Cdots (N-Cdots) with 3-(3,4-dihydroxyphenyl)-L-alanine (L-DOPA), L-histidine, and L-arginine as precursor models. After they are heated, the precursors become carbonized. Nitrogen-doped Cdots are subsequently extracted into N,N-dimethylformamide (DMF) from the carbogenic solid. A coreshell structure of Cdots with a carbon core and the oxygen-containing shell was observed. Nitrogen has different forms in N-Cdots and oxidized N-Cdots. The doped nitrogen and low oxidation level in N-Cdots improve their emission significantly. The N-Cdots show an emission with a nitrogen-content-dependent intensity and Cdot-size-dependent emission-peak wavelength. Imaging of HeLa cells, a human cervical cancer cell line, and HepG2 cells, a human hepatocellular liver carcinoma line, was observed with high resolution using N-Cdots as a probe and validates their use in imaging applications and their multicolor property in the living cell system.
