The fluoride pollution in environmental water can cause serious health problems, and the fluoride removal by sorbent is an effective strategy, and challenges by its poor selectivity and low capacity. Herein, we reported a new insight into the fabricating ultrafine zirconium oxide (ZrO2) based...

The two-dimensional (2D) organic-inorganic perovskite of unique optical properties and improved stability holds great potential in high-performance perovskite optoelectronic applications. However, a huge challenge to manufacture continuous thin films at large scale and low cost is still...

We examine economic mobility in India while accounting for misclassification to better understand the welfare e§ects of the rise in inequality. To proceed, we extend recently developed methods on the partial identification of transition matrices. Allowing for modest misclassification, we find...
