Atmospheric aerosols are one of the least understood components of the climate system and incur adverse health effects on susceptible populations. Organic aerosols can make up as much as 80% of atmospheric aerosols (Lim and Turpin
The research proposal describes the spectroscopic technique to study the intermediate state of protonated peptides formed after the UV excitation. It was shown previously that with the assistance of the CO2 laser the side chain loss fragmentation was enhan ...
Organic photodetectors are interesting for low cost, large area optical sensing applications. Combining organic semiconductors with discrete absorption bands outside the visible wavelength range with transparent and conductive electrodes allows for the fab ...
Tryptophan is commonly used to study protein structure and dynamics, such as protein folding, as a donor in fluorescence resonant energy transfer (FRET) studies. By using ultra-broadband ultrafast two-dimensional (2D) spectroscopy in the ultraviolet (UV) a ...

Giving the green light: The connection of two CrIII sensitizers around a central ErIII acceptor in a self-assembled cation provides high local metal concentrations that favor efficient nonlinear energy transfer upconversion luminescence (see picture). Upon ...
We present a method to automatically detect shadows in a fast and accurate manner by taking advantage of the inherent sensitivity of digital camera sensors to the near-infrared (NIR) part of the spectrum. Dark objects, which confound many shadow detection ...

Desirable components for dye-sensitzed solar cell ( DSC) sensitizers and fluorescent imaging dyes include strong donating building blocks coupled with well-balanced acceptor functionalities for absorption beyond the visible range. We have evaluated the eff ...
A camera for simultaneously capturing a visible and near-infrared (NIR) image of one or more objects, the camera comprising: at least one colour filter array (CFA) including at least four different filters, said at least one colour filter array having visi ...
For decades, the size-dependent optical properties of semiconductor nanocrystals have been explored to elucidate their fundamental electronic nature and develop their potential for optoelectronic devices. Recently, substitutional doping has emerged as a co ...
We report the design and characterization of a new molecular-beam/surface-science apparatus for quantum state-resolved studies of gas/surface reaction dynamics combining optical state-specific reactant preparation in a molecular beam by rapid adiabatic pas ...
