Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Advanced Materials, EarlyView.Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Advanced Materials, EarlyView.Left‐ and right‐handed circularly polarized light emission (CPLE) is observed from chiral “hedgehog” particles (CHIPs) coated with a nanofilm of achiral perovskite, with spectroscopic bands specific to the perovskites and chirality specific to the template CHIPs. Careful analysis of optical activity indicates that the CPLE of perovskite luminescence is

FLIP: an Internet protocol for flat labels
, 2016 In recent years the increasingly frequent use of the Web service, the advent of the cloud computing, the exponential growing of mobile devices with the introduction of pervasive and ubiquitous computing and the emergence of extreme distributed systems have brought to light the problem of the no longer adequate distribution of data packets over Internet

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane
Advanced Materials, EarlyView.Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

Advanced Materials, EarlyView.This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...
