Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Selective photo labeling of tryptophan in N‐acetyl‐L‐tryptophan ethyl ester and peptide WWCNDGR with a diaryl nitrenium ion

Photochemistry and Photobiology, EarlyView.
Visible light photolysis of a N‐(N,N‐diarylaminopyridinium) salt allows for covalent modification of a peptide. Mass spectrometry demonstrates that this procedure selectively labels tryptophan residues. Laser flash photolysis experiments show that bond formation occurs via a diarylnitrenium ion intermediate.

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

Photochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Insights Into the Mechanistic Assessment of Plasmon‐Induced Aqueous Degradation of Pharmaceuticals by TiO2/Ag Nano‐Composite

Water and Environment Journal, EarlyView.
ABSTRACT Pharmaceutical contaminants in potable water sources are ubiquitous and have resulted in lowered water quality. Thus, two common broad‐spectrum pharmaceuticals (tetracycline‐TC and ciprofloxacin‐CPF) were comparatively photo‐degraded using Ag‐doped TiO2 photocatalyst species containing Ag nanoparticles at 2.5, 5, and 7.5 wt%.
