Bioinspired Antiaging Binder Additive Addressing the Challenge of Chemical Degradation of Electrolyte at Cathode/Electrolyte Interphase.

Journal of the American Chemical Society, 2021
For layered transition metal oxides cathode-based lithium batteries, the chemical degradation of electrolytes leads to fast battery capacity decay, severely challenging their practical applications.

Anti‐Hydrolysis, UV Absorber, and Photostabilizer Additives Effect on Degradation of Poly(Butylene Adipate‐co‐Terephthalate) Biocomposite Film for Mulching Application

Polymers for Advanced Technologies
The accumulation of polyethylene (PE) plastics has driven agricultural practitioners to adopt biodegradable mulch (BDM) films, with poly(butylene adipate‐co‐terephthalate) (PBAT) emerging as a popular choice.

Photostabilization and cure kinetics of UV-curable optical resins containing photostabilizers

Macromolecular Research, 2007
The photostabilization and cure kinetics of UV-curable, optical resins containing various formulations of photostabilizers were investigated to determine the system with the highest cure conversion and durability. Photo-DSC analysis revealed that increasing the concentration of a UV absorber (UVA) decreased both the cross-link density and the cure rate

Photostabilizers for Azadirachtin‐A (A Neem‐Based Pesticide)

Journal of Environmental Science and Health, Part B, 2003
Photostability of azadirachtin-A (a neem based pesticide) has been studied without and with adding stabilizers such as ter. butyl-p-cresol, 8-hydroxy quinoline and ter. butyl hydroquinone as thin film on glass surface and on leaf surface under sunlight and UV light.

Research on the effect of photoprotectants on photostabilization of rotenone

Journal of Photochemistry and Photobiology B: Biology, 2009
This study examined the photostabilization of rotenone when exposed to ultraviolet light (UV) in the presence of some photoprotectants. Rotenone with and without photoprotectants in methanol were applied onto the surface of glass slides. The remaining concentration of rotenone was analyzed by HPLC at particular intervals.

Photostabilization of coatings. Mechanisms and performance

Progress in Polymer Science, 2000
Abstract The lifetime of organic coatings is reduced in outdoor applications by attacks of solar radiation, oxygen and atmospheric pollutants. Undesirable mechanical, physical and chemical consequences of the resulting degradation can be substantially restricted by properly selected photostabilizers.

Photostabilization of biocontrol agents by berberine

International Journal of Pest Management, 2001
We studied the photostabilizing effect of the isoquinoline alkaloid berberine on the following three model photounstable biocontrol agents: the bacterium Bacillus thuringiensis ( Bt ), the baculovirus Spodoptera littoralis nucleopolyhedrosis virus ( SlNPV ), and the entomopathogenic fungus Beauveria bassiana .

Photostabilization of Polymeric Materials

Journal of Macromolecular Science, Part A, 1996
Abstract Recent advances in our understanding of natural photoprotection mechanisms and the photophysical processes occurring in synthetic macromolecules and ultraviolet absorbing additives are reviewed. The application of photophysical measurements and ultrafast laser spectroscopy demonstrate that energy dissipation pathways in intramolecularly ...

Photostabilization of pesticides by clays and chromophores

Archives of Insect Biochemistry and Physiology, 1993
AbstractMechanisms for the photostabilization of pesticides by the use of clays and chromophores are described. The main mechanisms include energy transfer and steric hindrance, whereas the importance of mechanisms such as light scattering and hypsochromic shift is marginal. As an example for energy transfer we describe a procedure where the potent and

Synergism in the Photostabilization of Polymers

1987
The mechanisms of synergism of mixtures of light stabilizers with antioxidants and other additives are reviewed. Attention is centred on the most thoroughly studied mechanisms, viz. diffusion of antioxidants to the photoreaction zone, mutual protection of light stabilizer and antioxidant, quenching by light stabilizers of the excited states of ...
