THE MAN BEHIND THE CURTAIN: X-RAYS DRIVE THE UV THROUGH NIR VARIABILITY IN THE 2013 ACTIVE GALACTIC NUCLEUS OUTBURST IN NGC 2617 [PDF]
, 2013 After the All-Sky Automated Survey for SuperNovae discovered a significant brightening of the inner region of NGC 2617, we began a ∼70 day photometric and spectroscopic monitoring campaign from the X-ray through near-infrared (NIR) wavelengths. We report

Surface Modification of Fluorine‐Free Superhydrophobic Materials with (Ultra‐)Thin TiO2 Layers
Advanced Engineering Materials, EarlyView.Significant changes in wettability, with a reduction of 60o in the water conduct angle, are reported via the surface modification of fluorine‐free superhydrophobic thin films, prepared by aerosol‐assisted chemical vapor deposition, after coating a 4 nm layer of titanium dioxide on the surface using atomic layer deposition.

Advanced Engineering Materials, EarlyView.A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Multi-Messenger Astronomy: Cosmic Rays, Gamma-Rays, and Neutrinos
, 2003 Although cosmic rays were discovered a century ago, we do not know where or how they are accelerated. There is a realistic hope that the oldest problem in astronomy will be solved soon by ambitious experimentation: air shower arrays of 10,000 kilometer ...

Advanced Engineering Materials, EarlyView.A shape‐morphing, porous polyurethane film combines passive radiative cooling with folding to deliver multilevel heating‐and‐cooling control. High solar reflectance and midinfrared emissivity keep surfaces up to 3.5 °C cooler in direct sunlight, while photothermal triggering folds the film to absorb solar heat.

Advanced Engineering Materials, EarlyView.Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.
