In the consensus problem, processes must agree on a single value, given a set of proposals. It is used, for example, to implement statemachine replication [4], in which failure-independent processors are replicated to implement a reliable service. In this approach, the states of the replicas are consistently changed by applying deterministic commands from a sequence, each one agreed upon using ...

Substituted Benzoquinones, Photosystem II Acceptors Benzoquinones (BQ) substituted with alkyl or alkoxy groups 2,5-dimethoxy-3,6-dichloro-/>benzoquinone (DCDMQ), 2,3,5,6-tetramethoxy-/?-benzoquinone (TMQ) have been tested for their electron affinity and site of action in the photosynthetic electron transport chain in whole cells and chloroplasts. Both the substituted compounds were found to be ...

NQR studies o f a number of molecular complexes with p-chloronitrobenzene and o-chloronitrobenzene as acceptors and different hydrocarbons as donors were carried out. A linear relationship between the NQR shift and the ionization potentials o f the donors is obtained. Maksyutin’s idea o f a positive shift with respect to acceptors having a quadrupolar nucleus is shown to hold in those systems. ...

We study the electrical conductivity problem of DNA, applying the Holstein’s polaron model to a double strand of DNA. We show that the Holstein’s polarons act as donors and acceptors in DNA and that the existence of such donors and acceptors provides us the extrinsic semiconductor character of DNA. This character of DNA may explain with a unified point of view almost all the known results recen...

Electromicrobiology is the domain of those prokaryotes able to interact with charged electrodes, using them as electron donors and/or electron acceptors. This is performed via a process called extracellular electron transport, in which outer membrane cytochromes are used to oxidize and/or reduce otherwise unavailable insoluble electron acceptors. EET-capable bacteria can thus be used for a vari...

The intermolecular interactions of cocrystals can be controlled via selecting the donors and acceptors, then TPA properties selectively adjusted, promoting development materials prepared cocrystal engineering.

The low dielectric constants of conventional organic semiconductors leads to poor charge carrier photogeneration in homojunction organic solar cells due to large exciton binding energies. Increasing the dielectric constant can potentially enhance the spontaneous exciton dissociation rate at room temperature in homojunction cells, and decrease the charge carrier recombination in heterojunction s...

Perylene-imide derivatives are industrially important pigments that exhibit a variety of shades from red via maroon to black. In the present investigation, we have synthesized novel perylene-imide derivatives with pyridyl rings in an attempt to apply them for H2 gas sensors based on proton acceptors. The two N atoms of the pyridyl rings which work as proton acceptors are found to remain unbound...

In the title compound, C(13)H(19)NO(2), the piperidine ring has a chair conformation with the exocyclic N-C bond in an equatorial position. In the crystal, mol-ecules are linked head-to-tail by phenol O-H⋯O hydrogen bonds to hy-droxy-methyl-ene O-atom acceptors, forming chains which extend along [100]. These chains form two-dimensional networks lying parallel to (101) through cyclic hydrogen-bo...

We present a method to modulate the fluorescence of non-polar single squaraine-derived rotaxanes molecules embedded in a polar poly(methyl methacrylate) (PMMA) matrix under an external electric field. The electron transfer between single molecules and the electron acceptors in a PMMA matrix contributes to the diverse responses of fluorescence intensities to the electric field. The observed inst...
