Preparation of lipase/Zn3(PO4)2 hybrid nanoflower and its catalytic performance as an immobilized enzyme.
A facile and rapid method is reported in this paper to prepare a novel immobilized enzyme named lipase/Zn3(PO4)2 hybrid nanoflower. The growth mechanism of the nanoflower has been studied in detail and can be described as the following four steps: crystallization and coordination, in-situ precipitation, self-assembly, size growth. Addition amount of lipase, reaction temperature and stirring form a...

[Chem. Mater.] High Performance Humidity Fluctuation Sensor for Wearable Devices via Bioinspired Graphene-Polymer Heterogeneous Sensing Junction
Measurements of an individual’s water metabolism dynamical information can provide us rich biological information in a noninvasive way. This concept is hindered by the trade-off between the sensitivity and responsive velocity of traditional moisture sensors. Herein, inspired by the molecular detecting system based on weak bond interactions in natural organisms, we designed a new concept of a tuna...

Dimethyl sulfite as an additive for lithium bis(oxalate)borate/γ-Butyrolacton electrolyte to improve the performance of Li-ion battery.
Dimethyl sulfite (DMS) is studied as an additive in lithium bis(oxalate)borate (LiBOB)/γ-Butyrolacton(GBL) electrolyte with LiCoO2 cathode and mesocarbon microbeads (MCMB) anode. Electrochemical performances of LiCoO2/DMS-electrolyte/Li and Li/DMS-electrolyte/MCMB half cells are studied by cyclic voltammetry, battery cycler, scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy ...

Inserting phenylethynyl linker into triphenylamine-based hyperbranched polyimide for effectively tuning memory performance
In this paper, a novel triamine monomer, tris(4-(2-(4-aminophenyl) ethynyl) phenyl) amine) (TAEPA) had been designed and synthesized through Sonogashira coupling reaction. The phenylethynyl of TAEPA was inserted as aπ bridge into the D-A structure of hyperbranched polyimide (HBPI). This structure could tune the memory performance of HBPI based devices. The memory devices had been fabricated fro...

One-Step Carbonization Synthesis of Hollow Carbon Nanococoons with Multimodal Pores and Their Enhanced Electrochemical Performance for Supercapacitors
Hollow carbon capsules with multimodal pores are highly promising for developing novel electrode materials for high-performance electrochemical devices due to their more active sites for ion and electron transfer. However, at present, most of the previous efforts are focused on the multistep process for the synthesis of hollow carbon nanostructures with individual pores. Herein, hollow carbon na...

A Dual Templating Route to Three-Dimensionally Ordered Mesoporous Carbon Nanonetworks: Tuning the Mesopore Type for Electrochemical Performance Optimization
To well understand the effect of the mesopore type of ordered mesoporous carbons (OMCs) on enhancing energy storage and conversion is still a great challenge because of the extreme difficulties in exploring new methods to create OMCs with different types of mesopores. Herein, we develop an intriguing dual-templating co-assembly/hydrothermal approach to realize nanostructure engineering in OMCs w...

Effects of GO oxidation degree on GO/BuMgClsupported Ti-based Ziegler–Natta catalyst performance and nanocomposite properties
In the present research, three graphene oxide (GO)/n-butyl-magnesium chloride (BuMgCl)-supported Tibased Ziegler–Natta catalysts were synthesized by the reaction of Grignard reagent with GO at various oxidation degrees, followed by anchoring of TiCl4. The effects of GO oxidation degree and of the reaction conditions on in situ ethylene polymerization were investigated. The obtained PE/reduced G...

Rapid Preparation of Crosslinked N-doped Graphene by Burning Method for High-Performance Electrochemical Capacitors
We demonstrated here the crosslinked N-doped graphene (NG) can be rapidly prepared through a onestep burning process of graphene oxide. The doping process completed within 3 minutes and the N content in the obtained NG reached to 5.6%. The obtained crosslinked NG shows mesoporous structure with relatively high specific area, large pore volume and various N types. As a supercapacitor, the resulta...
