The Integral Field View of the Orion Nebula [PDF]
, 2014 This paper reviews the major advances achieved in the Orion Nebula through the use of integral field spectroscopy (IFS). Since the early work of Vasconcelos and collaborators in 2005, this technique has facilitated the investigation of global properties ...

Self‐Sustaining Piezozyme Platform for Antifouling via Mechanically Triggered Enzymatic Cascade
Advanced Science, EarlyView.Wave‐powered CeO2/g‐C3N4 piezozyme coating converts ocean motion into an enzymatic H2O2‐to‐ROS cascade, realizing 180‐day eco‐friendly marine antifouling. ABSTRACT Harnessing ubiquitous mechanical energy for catalytic activation offers an emerging pathway toward self‐sustaining environmental protection systems.

Advanced Science, EarlyView.A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...

Novel Vascular‐Adaptive Liquid Metal Microspheres Enable Visualized Arterial Embolization Therapy
Advanced Science, EarlyView.We present drug‐loaded liquid metal microspheres (X‐MEN) as a novel agent for image‐guided arterial embolization. With inherent radiopacity and superior deformability, X‐MEN enables real‐time monitoring and conforms tightly to irregular vessels. This approach ensures precise, long‐lasting embolization without recanalization, addressing critical ...

The Near-IR-Optical-UV Emission of BL Lacertae Objects
, 1994 Near--infrared, optical and ultraviolet quasi--simultaneous observations of 11 BL Lacertae objects are reported. For all but one source the dereddened spectral flux distribution in the $8\cdot10^{13}-2\cdot10^{15}$ Hz frequency range can be described by ...

Far-ultraviolet spectrophotometry of SPICA
The Astrophysical Journal, 1989 A spectrum of the star Spica (Alpha Virginis) from 960 to 1270 A was recorded by a rocket-borne spectrograph March 13, 1988. The spectrum, which has 3.4 A resolution, shows a much sharper drop-off in intensity near 1050 A than similar measurements made by the Voyager UVS, but is in good agreement with the spectrum obtained by Brune et al.

The star-formation histories of elliptical galaxies across the fundamental plane [PDF]
, 2006 We present the first results from a study designed to test whether, given high-quality spectrophotometry spanning the mid-UV--optical wavelength regime, it is possible to distinguish the metal content (Z) and star-formation history (sfh) of individual ...
