Thiol-functionalized conductive Co-MOF and its derivatives S-doped Co(OH) nanoflowers for high-performance supercapacitors.

The low conductivity of many traditional metal-organic-framework (MOF)-based electrode limits their developments in the field of electrochemical energy storage and still of great challenge. The controllable preparation of various kinds of nanomaterials using thiol-functionalized MOF shows great prospects. In this work, a thiol-functionalized metal-organic framework sheet structure (Co-MOF/NF) on nickel foam was successfully prepared by in situ interfacial growth synthesis, which was transformed into its derivatives S-doped β-Co(OH) nanoflowers Co-x/NF (x = 1, 2 and 6) in different concentrations of KOH solutions through ion etching/exchange reaction.

Particle size effect on surface/interfacial tension and Tolman length of nanomaterials: A simple experimental method combining with theoretical.

Surface tension and interfacial tension are crucial to the study of nanomaterials. Herein, we report a solubility method using magnesium oxide nanoparticles of different radii (1.8-105.

Application of 3D printing technology in tumor diagnosis and treatment.

3D printing technology is an increasing approach consisting of material manufacturing through the selective incremental delamination of materials to form a 3D structure to produce products. This technology has different advantages, including low cost, short time, diversification, and high precision. Widely adopted additive manufacturing technologies enable the creation of diagnostic tools and expand treatment options.

Visible-light-driven Oxygen Vacancy and Carbon Doping of C@TiO Photocatalyst for Enhanced Pollutants Degradation Performance.

Oxygen Vacancy (OVs) and carbon doping of the photocatalyst body will significantly enhance the photocatalytic efficiency. However, synchronous regulation of these two aspects is challenging. In this paper, a novel C@TiO photocatalyst was designed by coupling the surface defect and doping engineering of titania, which can effectively remove rhodamine B (RhB) and has a relatively high performance with wide pH range, high photocatalytic activity and good stability.

Critical size effect for the surface heat capacities of nano-CdS: theoretical and experimental studies.

The unique physical and chemical properties of nanomaterials are closely related to their surface thermodynamic functions, which mainly depend on their sizes. In this study, the thermodynamic properties of nano-cadmium sulphide (nano-CdS) were investigated by solubility technology. The nano-CdS powders with different particle sizes were prepared a traditional solvothermal method, and the electrical conductivities of nano-CdS aqueous solutions at different temperatures were measured.

Amperometric hydrogen peroxide biosensor based on immobilization of hemoglobin on a glassy carbon electrode modified with fe(3)o(4)/chitosan core-shell microspheres.

Novel magnetic Fe(3)O(4)/chitosan (CS) microspheres were prepared using magnetic Fe(3)O(4) nanoparticles and the natural macromolecule chitosan. Then, using an easy and effective hemoglobin (Hb) immobilization method, an innovative biosensor with a Fe(3)O(4)/CS-Hb-Fe(3)O(4)/CS "sandwich" configuration was constructed. This biosensor had a fast (less than 10 s) response to H(2)O(2) and excellent linear relationships were obtained in the concentration range of 5.
