Pressure Dissociation and Temperature Stability of Lactate Dehydrogenase (Oligomeric, Proteins, Conformational, Drift, Activity)
… did not carry out direct measurements of the molecular size they ascribe the slow reactivation at atmospheric pressure to the reassociation of the separated monomers. We have used fluorescence polarization methods (Paladini and Weber, 1982) to monitor the changes in molecular volume under …

Delaunay-Laguerre Geometry For Macromolecular Modeling And Implicit Solvation
… and implement algorithms for the calculation of molecular volume, atomic solvent accessible surface areas, their gradients and discontinuities. This is used for a detailed analysis of parameters obtained by the implicit solvation method, Semi-Explicit Assembly (SEA). We introduce the concept of …

Models of high-temperature desulfurization using zinc-based sorbents
… of the sorbent due to the difference in molecular volume of zinc oxide and zinc sulfide, grains size distribution, grain shape.;A bimodal size distribution of grains for the GPM was found to give the best match with the experimental data, but from particle SEM image, it was clear that …

Structure-activity relationships in Werner clathrates
… and UV/Visible Spectrophotometry. An intramolecular potential energy study on the [Ni(NCS)2(3,5-diMepy)4] complex reveals that the orthohydrogens on the 3,5-dimethylpyridine ligands control the conformation of the molecule. Packing densities and volume comparisons of the [Ni(NCS)2(4-Etpy)4] …

The Structure Function Relationship of Silica Polyamine Composites
… a polyamine to this moiety. MTCS has a smaller molecular volume than CPTCS and as a consequence greater coverage of the silica gel surface by silanes was determined by elemental analysis and NMR. An increase in the fraction of amines not attached to the surface (free amines) allowed improved …

An experimental investigation of the motion of flexible molecules in the liquid state by light scattering
… parameter R. From spectral analysis one obtains molecular reorientation times and in addition for the higher viscosity liquids values of R. The values of R are a weakly increasing function of chain length and almost independent of temperature. For pentadecane solutions in CC1(4), R is almost …

Improving of the accuracy and efficiency of implicit solvent models in Biomolecular Modeling
Biomolecular Modeling is playing an important role in many practical applications such as biotechnology and structure-based drug design. One of the essential requirements of Biomolecular modeling is an accurate description of the solvent (water). The challenge is to make this description …

A Unified Theory Characterising the Spontaneous Condensation Tendency of Working Fluids in Organic Rankine Cycle Expansion: Key Difference from Steam and its Implications
… that organic working fluids, characterised by a molecular size much larger than that of water, are much less likely to condense in a typical ORC expansion into the saturation dome, thereby allowing the expansion process to be situated entirely within the saturation dome without incurring the …
