a three-step selective photo-ionization for gd155 and gd157 isotopes by pulsed laser wasevaluated numerically. due to large thermal neutron absorption cross sections, these two isotopes innatural gadolinium are good candidates as burnable poison to control reactivity early in the fuel cycleand allow extended fuel burn up. rate equations have been used to calculate the dynamics of the isotopepop...

We demonstrated the photo-controlled sequence-selective dsDNA cleavage using a DNA origami structure with Cas9 nuclease.

A wavelength selective technique for light-induced network formation based on two photo-active moieties, namely ortho-methylbenzaldehyde and tetrazole is introduced. The network forming species are photo-reactive star polymers generated via reversible activation fragmentation chain transfer (RAFT) polymerization, allowing the network to be based on almost any vinylic monomer. Direct laser writi...

A straightforward photo-annealing approach was developed for building functional polymer layers on paper. Conducting polyaniline with the ability for photothermal conversion can be readily annealed by near-infrared light. The annealed polymers become both insulating and hydrophobic. Selective photo-annealing produces a functional layer with patterned conductive arrays. This material exhibits re...

Oxidized triangle terarylenes with asymmetric side-aryl units are synthesized, which show photo-induced turn-on yellow luminescence based on photochemical intramolecular ring-cyclization reaction in the solid state. A direct photo-patterning process for organic electroluminescent devices is successfully demonstrated with selective light irradiation through an appropriate mask-pattern.

An increase of the intracellular reactive oxygen species (ROS) concentration leads to the development of oxidative stress and, thus, to the damage of cell components. The cause-and-effect relations between these processes have not been fully established yet. The ability of photo excited supramolecular composites containing fullerenes C60 immobilized at nanosilica particles to generate reactive ...

The use of plastic nets is expanding to protect plants and production from hailstorms, excessive solar radiation damage flying pests. It under study the possibility reduce wetting due rain with a progressive increase mesh drive water out canopy photo-selective for higher photosynthesis fruit quality, growth control

The photo-oxidation of lysozyme (hen’s egg white), sensitized by methylene blue in 84% acetic acid solution, causes the selective modification of the methionyl residues, which are converted to the sulfoxide. The photo-oxidized protein shows a drastically reduced enzymic activity. The data obtained by comparing the sensitivity to proteolytic enzymes, as. well as the accessibility of disulfide bo...

We show for the ®rst time persistent spectral hole burning by simultaneous absorption of two 1138 nm photons in an inhomogeneously broadened S1 S0 …Qy† transition of unstable photo-tautomer of chlorin in polymer ®lm at low temperature. Spectrally selective hole burning is achieved due to high (10%) quantum eciency of photo-transformation in that system and high peak intensity (tens of GW/cm) o...
