Bias‐Tunable Two‐Terminal Organic Photodetector for Intelligent Imaging

Advanced Science, EarlyView.
A vertically stacked two‐terminal photodetector with a symmetric donor–acceptor–donor trilayer active exhibits reconfigurable photoresponse with bias‐tunable magnitude and polarity, together with sub‐millisecond response speed and a wide tunable output window.

The light-deficient climates of western Central African evergreen forests

Environmental Research Letters, 2019
Rainfall thresholds under which forests grow in Central Africa are lower than those of Amazonia and southeast Asia. Attention is thus regularly paid to rainfall whose seasonality and interannual variability has been shown to control Central African ...

Gonadal irradiation.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1974
A brief account is given of the circumstances under which gonadal irradiation may be expected to occur. The nonspecific tissue effect and the hormonal and sterilising effects are considered. Genetic implications are mentioned.S. Afr. Med. J., 48, 543 (1974).

Wavelength‐Dependent Photobiomodulation Regulates Macrophage Polarization via Mitochondrial Dynamics and Metabolic Reprogramming

Advanced Science, EarlyView.
Light wavelength encodes distinct macrophage fates through mitochondrial and metabolic remodeling. Red 625 nm irradiation induces glycolysis, mitochondrial fission, and M1 polarization, whereas near‐infrared 850 nm irradiation promotes fatty acid oxidation, mitochondrial fusion, and M2 polarization.

Primary Production: Sensitivity to Surface Irradiance and Implications for Archiving Data

Frontiers in Marine Science, 2017
An equation is derived to express the sensitivity of daily, watercolumn production by phytoplankton in the ocean to variations in irradiance at the sea surface.

Energy-specific solar radiation data from MSG: The Heliosat-3 Project

, 2006
Solar energy technologies such as photovoltaics, solar thermal power plants, passive solar heating/cooling systems and day lighting in buildings are expected to continue their very rapid growth.

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

Advanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

Effects of chilling and high temperatures on photosynthesis and chlorophyll fluorescence in leaves of watermelon seedlings

Biologia Plantarum, 2016
The effects of chilling (CT, day/night temperatures of 12/10 °C, an irradiance of 250 μmol m-2 s-1), chilling combined with a low irradiance (CL, 12/10 °C, 80 μmol m-2 s-1), and a high temperature (HT, 42/40 °C, 250 μmol m-2 s-1) on chlorophyll content ...

Irradiance models

, 2005
Measurements of solar irradiance have revealed variations at all the sampled time scales (ranging from minutes to the length of the solar cycle). One important task of models is to identify the causes of the observed (total and spectral)irradiance ...
