Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

The fate of heavy elements in dwarf galaxies - the role of mass and geometry

open access: yes, 2013
Energetic feedback from Supernovae and stellar winds can drive galactic winds. Dwarf galaxies, due to their shallower potential wells, are assumed to be more vulnerable to this phenomenon.

Advancing Self‐Assembled Molecules Toward Interface‐Optimized Perovskite Solar Cells: from One to Two

open access: yesAdvanced Materials, EarlyView.
In the past few years, self‐assembled molecules (SAMs) have ushered in a new era of interface engineering for perovskite solar cells. Herein, the recent progresses of co‐SAM, namely two SAMs with synergy, are comprehensively summarized and analyzed, focusing on topics including deposition methods and design principles, while further challenges about ...
