3D Printing of Functional Mesoporous Silica Monoliths with Embedded Metal and MOF Components
Advanced Functional Materials, EarlyView.This article presents the development of silica nanocage‐based nano‐inks tailored for digital light processing 3D printing, enabling automated additive manufacturing of mesoporous monoliths. Novel strategies for incorporating metal sites and inducing in situ growth of metal‐organic frameworks are introduced.

Planet at the crossroads [PDF]
Science, 2014 When we think of nature in 2014, chances are that protected areas come to mind: Amazonian rainforests teeming with wildlife, the sweeping plains of the Serengeti, or an Alpine lake surrounded by glaciers. But the world's protected areas are at a crossroads, and next month, when the International Union for Conservation of Nature (IUCN) convenes its once-

Advanced Functional Materials, EarlyView.This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...

Free-floating Planets, Survivor Planets, Captured Planets, and Binary Planets from Stellar Flybys
The Astrophysical JournalAbstract In star clusters, close stellar encounters can strongly impact the architecture of a planetary system or even destroy it. We present a systematic study of the effects of stellar flybys on two-planet systems. When such a system experiences flybys, one or both planets can be ejected, forming free-floating planets (FFPs), captured ...

Advanced Functional Materials, EarlyView.Halide diffusion limits the stability of hybrid halide perovskites for optoelectronic applications and thus needs to be quantified. This study presents an effective interdiffusion model to obtain time‐dependent diffusion coefficients for I− and Br− diffusion from in situ X‐ray diffraction data during the formation of a solid solution MAPbIxBr3‐x from ...
