The Role of the Distal and Proximal Protein Environments in Controlling the Ferric Spin State and in Stabilizing Thiolate Ligation in Heme Systems:Thiolate Adducts of the Myoglobin H93G Cavity Mutant
salicylic alcohols hydrogen bonds quantum chemistry
2016/5/23
Recently, heme protein cavity mutants have been engineered in which the proximal coordinating amino acid has been replaced by a smaller, noncoordinating residue leaving a cavity that can be filled by ...
Distance Dependence of Electron-Transfer Reactions in Organized Systems:The Role of Superexchange and Non-Condon Effects in Photosynthetic Reaction Centers
Distance Dependence Electron-Transfer Reactions Organized Systems Superexchange Non-Condon Photosynthetic Reaction Centers
2016/5/23
Extremely long distance electron transfer is observed in some photosynthetic reaction centers. For several charge recombination reactions, the rate appears to fall off much more slowly with distance t...
About diffusion in porous medium: the role of the correlation length
current transient electrochemical crystallization reaction diffusion kinetics porous systems
2012/5/29
In this paper we develop a model to describe the diffusion process in a porous medium. For the observed decrease in current yield, we propose other causes than difference in diffusivity, which we cons...
Role of quantum nuclei and local fields in the x-ray absorption spectra of water and ice
Role of quantum nuclei local fields the x-ray absorption spectra of water and ice Chemical Physics
2012/4/19
We calculate the x-ray absorption spectra of liquid water at ambient conditions and of hexagonal ice close to melting, using a static GW approach that includes approximately local field effects. Quant...

2011/9/1
Reaction probabilities as a function of total angular momentum (opacity functions) and the resulting reaction cross-sections for the collision of open shell S(1D) atoms with para- hydrogen have been c...
Role of a Binary Metallic Modifier in the Determination of Cadmium in Graphite Furnace Atomic Absorption Spectrometry
Binary Metallic Modifier Determination of Cadmium Graphite
2010/9/14
In order to discuss the matrix modifier effect of palladium, iron, and a mixture of palladium and iron for the determination of cadmium in graphite-furnace atomic absorption spectrometry (GF-AAS), we ...
Hydrogen storage via physisorption: the combined role of adsorption enthalpy and entropy
Adsorption thermodynamics enthalpy-entropy correlation hydrogen physisorption hydrogen storage
2010/4/8
Materials capable of cost-effective on-board hydrogen storage and delivery are currently being sought worldwide as a means to facilitate a hydrogen-based energy transition in the transportation sector...
The Role of the Entropy Factor on the Adsorption of an Optical Brightener on Pulp
Optical brighteners pulp adsorption entropy non-homogeneity
2010/4/9
The present paper reports results of the thermodynamic study of adsorption of 2 optical brighteners (Tinopal UP and Leucophor AP) on pulp. The entropy non-homogeneity of the pulp surface was confirmed...
Role of Carborane in Polymerization and Insertion Reactions
carborane polymerization insertion
2007/12/20
摘要 Ligand modifications have played a crucial role in developing new catalyst precursors. A novel class of “constrained-geometry” ligands bearing a carboanion functionality has been developed by linki...
