Peat particulate organic matter (POM) has been hypothesized to act as a terminal electron acceptor (TEA) for anaerobic microbial respiration in northern peatlands, thereby lowering dissolved methane (CH4) concentrations these systems. However, the redox properties of peat POM and an assessment its state situ remain missing, mainly due lack accurate analytical approach quantify number electrons ...

Molecular dynamic (MD) simulations have been performed on Tth-MCO, a hyperthermophilic multicopper oxidase from thermus thermophilus HB27, in the apo as well as the holo form, with the aim of exploring the structural dynamic properties common to the two conformational states. According to structural comparison between this enzyme and other MCOs, the substrate in process to electron transfer in ...

We investigate the electron injection from a terrylene-based chromophore to the TiO2 semiconductor bridged by a recently proposed phenyl-amide-phenyl molecular rectifier. The mechanism of electron transfer is studied by means of quantum dynamics simulations using an extended Hückel Hamiltonian. It is found that the inclusion of the nuclear motion is necessary to observe the photoinduced electro...

Supramolecular interaction is rapidly emerging as the method of choice for tuning molecular properties to meet desired applications like drug delivery vehicles, sensors, designing molecular architectures, catalysis chambers, biomimetic systems and so on. We have successfully demonstrated the modulation of electron and proton transfer reactions, acidbase characteristics and photophysical propert...

The covalent linking of acceptor molecules to electron donating conjugated polymer is an approach for the development of new photoactive materials for the fabrication of organic photoelectric conversion devices. With this strategy we have designed a polyalkylthiophene copolymer series containing in the side chain anthraquinone molecules as electron acceptor. The peculiar features of the copolym...
