Innovative cobalt-doped Fe3O4 nanocrystalline particles were effectively prepared via chemical coprecipitation in an aqueous solution. Co0.2Fe2.8O4 demonstrated highly efficient and recyclable properties in the hydrogenation of nitroarenes at low temperaturesin absolute water and at atmospheric pressure, resulting in~100% yield and selectivity.

A facile inside-out Ostwald ripening route to the morphology-controlledpreparation of TiO2 microspheres is developed. After recrystallization, hollow microspheres and solid microspheres have improved porosity, larger pores, higher surface areas and reduced trap states (Ti3+ and oxygen vacancy), which significantly enhance the photovoltaic performance of dye-sensitized solar cells based on these microspheres.

Ternary supramolecular nanoparticle networks (NPN) can be applied for Concanavalin A (ConA) detection: NPN form and flocculate due to the orthogonal binding of bifunctional linker molecules to quantum dots and lectins. Monitoring the decrease in quantum-dot fluorescence intensity over time, caused by controlled network formation and flocculation, allows for selective and sensitive, qualitative and quantitative lectin detection.

2,3-bis(4-(phenyl(4-(1,2,2-triphenylvinyl) phenyl)amino)phenyl)fumaronitrile (TPE-TPA-FN, or TTF), which is a typical aggregation-induced emission (AIE) luminogen, was encapsulated by amphiphilic polymers to form TTF-nanodots that emitted bright three-photon fluorescence under 1,560 nm-femtosecond laser excitation. The organic nanodots were microinjected into the embryos and hearts of zebrafish. The labeling allowed monitoring of the different growth stages of embryos as well as the morphologies of the heart and blood vessels using a three-photon fluorescence microscope.

Three-dimensional bismuth sulfur nanoflower superstructures were assembled into crumpled-paper-like nanosheets to serve as light-cavity mirrors, exhibiting improved intense near-infrared (NIR)absorption with enhanced photothermal conversion efficiency, and producing an effective cancer cell ablation therapy in vitro and in vivo.

The photoluminescence (PL) feature of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) nanorods (NRs) strongly depends on the NR morphology. The parallel relation between the electric field plane and molecular plane induces enhanced absorption in the visible region.

Photocatalytic reduction of CO2 with water using modified anatase TiO2 nanofibers under UV light proceeds via a hydrogenation pathway. The enhanced activity of modified TiO2 nanofibers towards CO2 photoreduction is demonstrated experimentally and theoretically by density functional theory (DFT) calculations. The synergistic effect of CdSe quantum dots (QDs) and Pt on TiO2 nanofibers was found to be optimal for methanol formation under the experimental conditions.

A one-step pyrolysis method was used to prepare a reduced SnO2–x/g-C3N4 Z-type heterojunction material that exhibited high photocatalytic and photoelectrochemical activity under visible-light-emittingdiode irradiation.
