Advanced Materials, EarlyView.A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

CME-Associated Radio Bursts from Satellite Observations [PDF]
, 2012 Coronal mass ejections (CMEs) are closely associated with various types of radio bursts from the Sun. All radio bursts are due to nonthermal electrons, which are accelerated during the eruption of CMEs.

Machine learning, real-time techniques for the discovery, analysis and study of Fast Radio Bursts
, 2020 Fast Radio Bursts (FRBs) are brief, bright flashes observed in the radio spectrum whose origins remain a mystery. Originating from half-way through the universe, and carrying the imprint of the media they propagate through on their billion-year-long ...

Advanced Materials, EarlyView.Organic artificial neurons couple mechanical deformation and ionic environments through nonlinear mechano‐electrochemical dynamics. Mechanical strain and electrolyte concentration reshape their nonlinear electrical characteristics, programming excitatory or inhibitory spiking responses that mimic mechanosensitive biological neurons and enable ...
