Simple preparation of a CuO@γ-AlO Fenton-like catalyst and its photocatalytic degradation function.

We designed a photocatalyst and developed sustainable wastewater purification technology, which have significant advantages in effectively solving the global problem of drinking water shortage. In this study, a new nanocomposite was reported and shown to be a catalyst with excellent performance; CuO was coated successively onto functionalized nano γ-AlO, and this novel structure could provide abundant active sites. We evaluated the performance of the CuO@γ-AlO nanocomposite catalyst for polyvinyl alcohol (PVA) degradation under visible light irradiation.

Facile Synthesis of a Color-Tunable Microcrystal Phosphor for Anti-Counterfeit Applications.

Developing luminescent materials with tunable emission colors provides exciting opportunities for application in the display, anti-counterfeiting, and optical sensors. Here, we report a convenient, versatile approach to synthesize color-tunable, up/down-conversion luminescence in an inorganic host material. The emission color can be tuned by varying the excitation wavelength, allowing dynamic color tuning in the visible spectrum.

Fabrication and characterization of multi stimuli-responsive fibers via wet-spinning process.

Luminescent fibers have attracted much attention due to their application in smart textiles for anti-counterfeiting, camouflage, fashion designs and so on. However, fibers with single function of luminescent is fail to meet the growing demand of smart textiles. Herein, we develop a multifunctional fiber with quick-responsive reversible photochromic and light-emitting with long afterglow.

Soft, Stretchable, and Pneumatically Triggered Thermochromic Optical Filters with Embedded Phosphorescence.

Phosphorescence is commonly used in nature to communicate using light. There are many ways to activate phosphorescence, including UV light, heat, and mechanical forces, but there are few methods to control phosphorescence once activated. Here, we present soft composite devices-which we call "optical filters"-for controlling the release of light by phosphorescence within a stretchable matrix.

Design and Synthesis of Core-Shell Carbon Polymer Dots with Highly Stable Fluorescence in Polymeric Materials.

In recent years, fluorescent carbon dots have attracted great attention due to their good luminescence and low toxicity. Here, blue fluorescent core-shell structured carbon polymer dots (CPDs) with high stability under a wide range of pH values, long storage time and excellent fluorescence in various solvents and even in solid state were prepared by hydrothermal synthesis of dendritic tris(2-aminoethyl)amine (TAEA) and citric acid. The CPDs core structure provides strong fluorescent luminescence, a shell structure of the core possesses high amount of dendritic primary amino groups connected by ethylene groups to the core.

Materials tactile logic via innervated soft thermochromic elastomers.

Conventional machines rely on rigid, centralized electronic components to make decisions, which limits complexity and scaling. Here, we show that decision making can be realized on the material-level without relying on semiconductor-based logic. Inspired by the distributed decision making that exists in the arms of an octopus, we present a completely soft, stretchable silicone composite doped with thermochromic pigments and innervated with liquid metal.

Scalable synthesis of high-purity TiO whiskers ion exchange method enables versatile applications.

In this work, high-purity titanium dioxide (TiO) whiskers with different crystal forms were synthesized ion exchange and controlled calcination methods. TiO whiskers are of 5-10 μm in length with a length-to-diameter ratio of 10-20. A systematic investigation was established to explore the hydration process of K/H exchange, anatase-rutile transformation in the calcination process and the applications of TiO whiskers.

Excitation Wavelength-Dependent Dual-Mode Luminescence Emission for Dynamic Multicolor Anticounterfeiting.

Luminescent materials have become prevalent in data communication and information security because of their special optical characteristics. Conventional luminescent materials generally exhibit unicolor emission and fixed excitation mode, resulting in decreased efficiency of anticounterfeiting applications. The development of an iridescent chameleon-like material that can change its emission color under different stimulations is a significant challenge.

Novel hollow α-Fe2O3 nanofibers via electrospinning for dye adsorption.

Nanomaterials such as iron oxides and ferrites have been intensively investigated for water treatment and environmental remediation applications.
