Rigid p-octiphenyl rods were used to create helical tetrameric p-stacks of blue, red-fluorescent naphthalene diimides that can span lipid bilayer membranes. In lipid vesicles containing quinone as electron acceptors and surrounded by ethylenediaminetetraac ...
Two org. dyes with the general structure donor-conjugated chain-acceptor (D-π-A) were studied as sensitizers for nanocryst. TiO2 solar cells. The electron donor and acceptor groups were pyrrolidine and cyano acrylic acid, resp. The conjugated chain of 2-cy ...
Groundwater contamination by organochloric compounds became a major concern for public health during the last century. Chloroethenes, commonly used since the 1920's as degreasing and cleaning agents and as intermediates in chemical synthesis, accumulated i ...
Linear alkylbenzenes (LABs) are common environmental contaminants associated with a range of industrial and domestic activities. Although natural environments receiving LABs may exhibit a range of redox conditions, until now only aerobic biodegradation of ...
Unusual diglycosides composed of D-hexofuranosyl entities were prepared by a chemoenzymatic route using the -L-arabinofuranosidase, AbfD3. The required, unprotected monosaccharidic donors were first prepared according to multi-step syntheses. Since one goa ...
Electron transport in fusion plasmas is intensively studied in coordinated experiments and great progress in physics understanding has been achieved during the past years. A threshold in normalized gradient explains most of the observations, both in steady ...
Tetra- (PCE) and trichloroethene (TCE) are major groundwater pollutants due to their extensive industrial use. Several anaerobic bacteria have been isolated using chloroethenes as terminal electron acceptor. Most of these bacteria dechlorinate PCE and TCE ...
Hexanethiolate monolayer-protected gold nanoclusters (MPCs) were used as redox quenchers at the polarizable water/1,2-dichloroethane (DCE) interface. Photocurrent responses originating from the heterogeneous quenching of photoexcited water soluble porphyri ...
This study focuses on the mineralization of 5-amino-6-methyl-2-benzimidazolone (AMBI), an important precursor in the industrial production of dyes, through an integrated Fe(III) photoassisted–biological system without addition of other electron acceptor th ...
The effect of the excitation wavelength on the charge recombination (CR) dynamics of several donor−acceptor complexes (DACs) composed of benzene derivatives as donors and of tetracyanoethylene or pyromellitic dianhydride as acceptors has been investigated ...
