Spring and summer time ozone and solar ultraviolet radiation variations over Cape Point, South Africa [PDF]

Annales Geophysicae, 2019
The correlation between solar ultraviolet radiation (UV) and atmospheric ozone is well understood. Decreased stratospheric ozone levels which led to increased solar UV radiation levels at the surface have been recorded. These increased levels of solar UV

Intraspecific variation in photosynthetic efficiency in soybean (Glycine max L.) varieties towards solar ultraviolet radiations

Photosynthetica, 2023
In the current study, we used four soybean varieties PK-1029, PK-472, NRC-7, and Hardee to examine the effect of exclusion of solar UV radiation on photosynthetic efficiency and to test possible variety-dependent sensitivity to ambient UV (280-400 nm ...

A Visual Solar UV Sensor Based on Paraffin-Perovskite Quantum Dot Composite Film.

ACS Applied Materials and Interfaces, 2019
Nowadays, people are facing more and more threats from solar UV radiation due to global ozone layer depletion and the ozone hole. Therefore, it is highly desirable to develop a fast, simple, and sensitive sensor for solar UV radiation.

Mathematical Assessment of Aerosol Impact on the Diffuse-to-Global Ratio of Solar UV Radiation

Mathematics
This study is devoted to investigating the effect of aerosols on solar UV radiation. In the ultraviolet range, scattering processes are dominant and lead to a substantial contribution of diffuse UV radiation to the global UV irradiance.

Orientation to the sun by animals and its interaction with crypsis [PDF]

, 2015
1. Orientation with respect to the sun has been observed in a wide range of species and hasgenerally been interpreted in terms of thermoregulation and/or ultraviolet (UV) protection. For countershaded animals, orientation with respect to the sun may also

Long-term changes in UV and EUV solar radiation [PDF]

Geofísica Internacional, 2000
Total solar irradiance (TSI) may present the same long-term variation as the solar cycle length (SCL), corresponding to the Gleissberg cycle. It is expected that when SCL decrease, TSI increase.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.
