Experimental and Theoretical Studies of the Environmental Sensitivity of the Absorption Spectra and Photochemistry of Nitenpyram and Analogs [PDF]
, 2019 Neonicotinoid (NN) pesticides have widespread use, largely replacing other pesticides such as the carbamates. Hence, there is a need to understand their environmental fates at a molecular level in various media, especially water.

Angewandte Chemie International Edition, Accepted Article.The field of visible light‐mediated photochemistry has experienced significant growth, leading to the development of a wide array of methodologies in synthetic organic chemistry. In particular, photocatalysis by using long‐wavelength light such as red and near‐infrared (NIR) light has garnered substantial attention recently.

Lanthanide-Doped Upconversion Nanocarriers for Drug and Gene Delivery
Nanomaterials, 2018 Compared to traditional cancer treatments, drug/gene delivery is an advanced, safe, and efficient method. Nanoparticles are widely used as nanocarriers in a drug/gene delivery system due to their long circulation time and low multi-drug resistance.

Observation of Selective Isotope Effect in the Ultraviolet excitation of N2: A Computational Study [PDF]
arXiv, 2011 Isotope effects associated with gas phase N2 photolysis are used to interpret Martian atmospheric evolution, icy satellite atmospheric chemistry and meteorite isotopic anomalies from nebular N2 photochemistry. To interpret observations at the highest level, fundamental understanding of the precise wavelength dependency of the process must be known.

Particulate Nitrate Photolysis as a Possible Driver of Rising Tropospheric Ozone
Geophysical Research LettersTropospheric ozone is an air pollutant and a greenhouse gas whose anthropogenic production is limited principally by the supply of nitrogen oxides (NOx) from combustion. Tropospheric ozone in the northern hemisphere has been rising despite the flattening

The Impact of Extended CO$_2$ Cross Sections on Temperate Anoxic Planet Atmospheres [PDF]
arXivOur interpretation of terrestrial exoplanet atmospheric spectra will always be limited by the accuracy of the data we use as input in our forward and retrieval models. Ultraviolet molecular absorption cross sections are one category of these essential model inputs; however, they are often poorly characterized at the longest wavelengths relevant to ...

Formation of hydroxyl radicals from photolysis of secondary organic aerosol material
, 2015 . This paper demonstrates that OH radicals are formed by photolysis of secondary organic aerosol (SOA) material formed by terpene ozonolysis. The SOA is collected on filters, dissolved in water containing a radical trap (benzoic acid), and then exposed ...
