UV aging may enhance adsorption capacity of Poly (butylene adipate-co-terephthalate) (PBAT) to heavy metals and toxicity to zebrafish.

Aquatic Toxicology
Compared with the fossil-based plastics, biodegradable plastics are more easily decomposed into small-sized particles (e.g., microplastics). However, the role of aged biodegradable plastics in being vector of co-existed pollutants and potential ...

UV Damage and Photoreactivation: Timing and Age are Everything ¶

Photochemistry and Photobiology, 2003
Aquatic organisms, ranging from bacteria to fish, living in clear lakes are presently receiving damaging levels of UV radiation. Photoreactivation is a light-dependent mechanism by which some organisms deal with DNA damage caused by UV radiation. Yet, photoreactivation is a mechanism that confounds long-term predictive modeling of UV effects on the ...

Photo-catalytic degradation of gaseous formaldehyde by TiO2/UV, Ag/TiO2/UV and Ce/TiO2/UV

Building and Environment, 2012
Abstract As a main indoor air pollutant, formaldehyde was chosen as the aim pollutant. Nano-structured TiO2, Ag–TiO2 and Ce–TiO2 thin films were prepared by sol–gel method at room temperature and used in the photo-catalyst reactor for HCHO decomposition.

X‐ray and UV photoelectron spectroscopy of Ag nanoclusters

Surface and Interface Analysis, 2020
The main purpose of the present work is to analyze a series of Ag nanoparticles (NPs) with different size or ligand functionalization by using X‐ray photoelectron spectroscopy (XPS) and to identify the differences in the band‐shape and energy peak position of photoemission spectra due to the particle dimension.

UV-aging reduces the effects of biodegradable microplastics on soil sulfamethoxazole degradation and sul genes development.

Journal of Environmental Science
In recent years, the biodegradable plastics has extensively used in industry, agriculture, and daily life. Herein, the effects of two biodegradable microplastics (BMPs), poly(butyleneadipate-co-terephthalate) (PBAT) and polyhydroxyalkanoate (PHA), on ...

UV aging assessment of asphalt binder: influence of duration, zinc oxide, and aging condition

International Journal of Pavement Engineering
Ultraviolet radiation penetrates the atmosphere resulting in photo-oxidative aging of asphalt. The conventional long-term aging method, such as pressure-aging vessel, ages the asphalt considering thermo-oxidative principle.

Effect of a lignin-based polyurethane on adhesion properties of asphalt binder during UV aging process

, 2020
Polyurethane is gradually used to chemically modify asphalt binder due to its outstanding compatibility with asphalt binder. One of the plant wastes (lignin) containing hydroxyl groups on its surface can replace one of the raw materials (polyether polyol)

UV Aging Performance of Asphalt Containing LDHs

Key Engineering Materials, 2014
In this paper the effect of Layered double hydroxides (LDHs) on aging properties of asphalts was studied. The thin film oven test TFOT tests and ultraviolet (UV) aging process were used to simulate short-term and long-term aging of asphalts, respectively.
