Development of UHF radiometer

open access: yes, 1985
A wideband multifrequency UHF radiometer was initially developed to operate in the 500 to 710 MHz frequency range for the remote measurement of ocean water salinity.

Exploring natural sunscreens: UVB protection and antioxidant properties in gadusol‐rich fish roes extracts

open access: yesPhotochemistry and Photobiology, EarlyView.
Gadusol‐rich extracts provide effective UVB protection and antioxidant activity in HaCaT cells and C. elegans, highlighting their potential as natural photochemoprotective agents for pharmaceutical and cosmetic applications. It also demonstrates remarkable in vitro antioxidant capacity and thermal stability over time.

Alleviation of photoaging‐associated MMP upregulation, prostanoid biosynthesis, and cell cycle arrest with titanium dioxide, zinc oxide, and inorganic‐only (ZnO + TiO2) sunscreens

open access: yesPhotochemistry and Photobiology, EarlyView.
Inorganic sunscreens containing the UV filters titanium dioxide (TiO2) and/or zinc oxide (ZnO) alleviated various biomarkers of photoaging in human dermal fibroblasts, at a gene and protein level. The study provides novel insights that observe the impact of inorganic photoprotection through the molecular biology of skin.

Possible involvement of keratinocyte‐derived microvesicle particles in human photosensitivity disorders

open access: yesPhotochemistry and Photobiology, EarlyView.
In this model, ROS generated by UVB result in PAFR agonists acting upon the PAFR resulting in MVP generation release via the enzyme aSMase. In photosensitivity, there are increased ROS, resulting in augmented PAF agonists and increased MVP release. This process can be blocked by aSMase inhibitors.

Evaluating tools for predicting and measuring radiometric performance of germicidal ultraviolet systems

open access: yesPhotochemistry and Photobiology, EarlyView.
An evaluation of simulation and measurement tools for germicidal ultraviolet (GUV) systems is presented to inform their design and deployment to control the spread of airborne pathogens. Abstract Germicidal ultraviolet (GUV) air treatment technologies can be effective and safe for reducing airborne disease transmission.

Measurement and modeling of diffuse ultraviolet radiation: A review

open access: yesPhotochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.
