Highly efficient visible-light-induced photocatalytic activity of nanostructured AgI/TiO2 photocatalyst.

Abstract: Nanostructured AgI/TiO2 photocatalyst was synthesized by a feasible approach with AgNO3, LiI, and Ti(OBu)4 and characterized by X-ray diffraction, transmission electron microscopy, angle-dependent X-ray photoelectron spectroscopy, diffusive reflectance UV−vis spectroscopy, Raman spectroscopy, photoluminescence, and the Brunauer−Emmett−Teller technique. The results of characterization reveal that the nanostructured AgI/TiO2 has a novel core/shell/shell nanostructure of AgI/Ag−I2/TiO2. Compared with TiO2 (P25) supported AgI, the formation of the nanostructure results in substantial shifting of the absorption edge of AgI to red, enhancement of the absorption intensity, and the appearance of a strong tail absorption above 490 nm, which is assigned to the absorption of I2 and Ag. Photocatalytic tests show that the nanostructured AgI/TiO2 photocatalyst exhibited very high visible-light-induced photocatalytic activity for the photodegradation of crystal violet and 4-chlorophenol, which is 4 and 6 times higher th...

Compliant and stretchable thermoelectric coils for energy harvesting in miniature flexible devices

Abstract: With accelerating trends in miniaturization of semiconductor devices, techniques for energy harvesting become increasingly important, especially in wearable technologies and sensors for the internet of things. Although thermoelectric systems have many attractive attributes in this context, maintaining large temperature differences across the device terminals and achieving low–thermal impedance interfaces to the surrounding environment become increasingly difficult to achieve as the characteristic dimensions decrease. Here, we propose and demonstrate an architectural solution to this problem, where thin-film active materials integrate into compliant, open three-dimensional (3D) forms. This approach not only enables efficient thermal impedance matching but also multiplies the heat flow through the harvester, thereby increasing the efficiencies for power conversion. Interconnected arrays of 3D thermoelectric coils built using microscale ribbons of monocrystalline silicon as the active material demonstrate these concepts. Quantitative measurements and simulations establish the basic operating principles and the key design features. The results suggest a scalable strategy for deploying hard thermoelectric thin-film materials in harvesters that can integrate effectively with soft materials systems, including those of the human body.
