Advanced Science, EarlyView.A novel multifunctional scaffold with photothermal effects is developed for infected bone defect repair. It facilitates angiogenesis and osteogenesis while eliminating bacteria through hyperthermia. Additionally, the scaffold promotes macrophage polarization from M1 to M2 via ROS scavenging, enhancing anti‐inflammatory activity. This study demonstrates

Frame‐Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design
Angewandte Chemie, EarlyView.Modern chemistry seeks to turn the simple raw materials into complex molecules that matter in health, agriculture, and technology. Among these, oligoheterocycles stand out for their versatility, yet they are most often built by cross‐coupling reactions that often rely on expensive metal catalysts.

Optimal Occulter Design for Finding Extrasolar Planets
, 2007 One proposed method for finding terrestrial planets around nearby stars is to use two spacecraft--a telescope and a specially shaped occulter that is specifically designed to prevent all but a tiny fraction of the starlight from diffracting into the ...

A 3% SOLUTION: DETERMINATION OF THE HUBBLE CONSTANT WITH THE HUBBLE SPACE TELESCOPE AND WIDE FIELD CAMERA 3 [PDF]
, 2011 We use the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) to determine the Hubble constant from optical and infrared observations of over 600 Cepheid variables in the host galaxies of eight recent Type Ia supernovae (SNe Ia), providing ...

Fermi Large Area Telescope Third Source Catalog [PDF]
, 2015 We present the third Fermi Large Area Telescope (LAT) source catalog (3FGL) of sources in the 100MeV– 300 GeV range. Based on the first 4 yr of science data from the Fermi Gamma-ray Space Telescope mission, it is the deepest yet in this energy range ...

Surface Adhesion Engineering for Armored Metasurfaces and Beyond
Advanced Science, EarlyView.Targeting primary causes of dysfunctionality in optical systems, an “armored” metasurface is developed based on Persson's model and Hertzian theory, enabling anti‐dust, anti‐scratch, anti‐impact, and anti‐water, heat resistance capabilities, alongside excellent optical antireflection performance.
