Omnidirectional Transmissive Acoustic Metasurfaces Based on Goldberg Polyhedra

Advanced Functional Materials, EarlyView.
This study introduces omnidirectional acoustic metasurfaces capable of manipulating wavefronts in multiple arbitrary directions simultaneously. A full‐stack pipeline for design, optimization, and fabrication is presented to construct near‐spherical holograms based on Goldberg polyhedra.

Comparison of the Performance of Poly Aluminum Chloride with Natural Co-coagulants in Removal of Turbidity from synthetic aqueous solution

Muhandisī-i Bihdāsht-i Muḥīṭ, 2014
Background: Contaminated water, naturally or by human, should be processed to become drinking water. Coagulation is a process that fine unsettling particles which called colloids and are important factors in the turbidity occurrence, join together and ...

Versatile Green Transfer of Magnetoelectronics with Loss‐Free Performance and High Adhesion for Interactive Electronics

Advanced Functional Materials, EarlyView.
An environmentally friendly transfer printing method of nm‐thick giant magnetoresistive (GMR) sensors is demonstrated. This method, relying on water and biocompatible polyvinyl alcohol (PVA) polymer without the need of complex treatments, allows transferring thin films to a wide range of biological, organic, and inorganic substrates.

Photocatalytic Degradation of Rhodamine B with H3PW12O40/SiO2 Sensitized by H2O2

International Journal of Photoenergy, 2012
In order to remove aquatic organic dye contaminants by utilizing the inexpensive and inexhaustible solar energy, the Keggin-type H3PW12O40 was loaded on the surface of SiO2 with the sol-gel method and sensitized by H2O2 solution.

Tailoring the Microstructure of B‐Cation Octahedra in Halide Double Perovskites for Efficient Selective CO2‐to‐CO Photoreduction

Advanced Functional Materials, EarlyView.
The thermodynamic obstacle of CO2‐to‐CO conversion over metal halide perovskite photocatalysts is addressed by modulating the local electronic structure. A 13‐fold improvement in selective CO2 photoreduction to CO is achieved, with ≈100% selectivity.

A context-aware e-bike system to reduce pollution inhalation while cycling [PDF]

arXiv, 2017
The effect of transport-related pollution on human health is fast becoming recognised as a major issue in cities worldwide. Cyclists, in particular, face great risks, as they typically are most exposed to tail-pipe emissions. Three avenues are being explored worldwide in the fight against urban pollution: (i) outright bans on polluting vehicles and ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

Advanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...
