A Data-driven Search For Mid-infrared Excesses Among Five Million Main-sequence FGK Stars

The Astronomical Journal
Stellar infrared excesses can indicate various phenomena of interest, from protoplanetary disks to debris disks, or (more speculatively) techno-signatures along the lines of Dyson spheres.

Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

Advanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced 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

Electrospun Lignin/ZnO Nanofibrous Membranes for Self‐Powered Ultrasensitive Flexible Airflow Sensor and Wearable Device

Advanced Materials, EarlyView.
This study explores the novel sensing applications of water evaporation‐induced power generation, by using lignin/ZnO nanofibrous membranes for sensing airflow through output voltage variation. Obtained lignin/ZnO airflow sensors are self‐powered, precise, and quick‐responding, and can be used as wearable devices for breath monitor, surrounding ...
