Decay and rot are established motifs in art history. They address transience disgust, as well contemplation, devotion humility through the tradition of Memento Mori. In contrast to pure motific depictions decay, Finnish artist Toni R. Toivonen (*1987) arranges deceased animals creates works, which organic components such fur, muscles, flesh blood decompose until dissolution. Organic decompositi...

—The exceptionally preserved fossil record of soft tissues sheds light on a wide range of evolutionary episodes from across geological history. Understanding how soft tissues become hard fossils is not a trivial process. A powerful tool in this context is experimentally derived decay data. By studying decay in a laboratory setting and on a laboratory timescale, an understanding of the processes...

We report on an experimental study of the charge transfer dynamics in a P3HT : PCBM blend by means of a femtosecond fluorescence up-conversion technique. Using two-photon excitation we probe the exciton dynamics in P3HT and a P3HT : PCBM blend with a weight ratio of 1 : 1 at excitation densities of up to 6 × 1018 cm−3. In both samples we find strongly nonexponential decay traces compatible with...

Time-resolved fluorescence spectroscopy is a powerful analysis tool in fundamental physics as well as in the life sciences. Implementing it in the time domain requires recording the time dependent intensity profile of the emitted light upon excitation by a short flash of light, typically a laser pulse. While in principle, one could attempt to record the time decay profile of the signal from a s...

The gradual elimination of chromium from wood preservative formulations results in higher Cu leaching and increased susceptibility to wood decay fungi. Finding a sustainable strategy in wood protection has become of great interest among researchers. The objective of these in vitro studies was to demonstrate the effect of T-720-enriched organic charcoal (biochar) against five wood decay basidiom...

A new membrane probe, based on the perylene imide chromophore, with excellent photophysical properties (high absorption coefficient, quantum yield (QY) approximately 1, high photostability) and excited in the visible domain is proposed for the study of membrane rafts. Visualization of separation between the liquid-ordered (Lo) and the liquid-disordered (Ld) phases can be achieved in artificial ...

Diisopropyl Ether, Hydroxyl Radicals, Peroxyl Radicals, Pulse Radiolysis In the radiolysis of N 2 0/0 2 (4 :1 )-saturated aqueous solutions of diisopropyl ether(10~ mol dm ~), OH radicals abstract H-atoms, thereby producing radicals at C(2) (1 = 78%) and to a lesser extent at C(l) (2 — 22%) which are converted by oxygen into the corresponding peroxyl radicals 3 and 4. Some 0 2 radicals are form...
