packing factordilatancymeltingcrystallizationglass transitionThe dependence of the first coordination number k n on the packing factor k y is obtained for four cubic structures: fcc, bcc, simple cubic, and diamond. The k n ( k y ) dependence is described by a third-degree polynomial k n = ...
In particular, resolution and R-factor thresholds ensure that unreliable structures are excluded from the analyzed data sets; moreover, we considered a homogeneous set containing only low temperature crystal structures, which are now the routine, since packing might depend on temperature; furthermore,...
The ratio of the volume of atoms in a cell compared to the total volume of a cell is the packing factor or packing fraction. The packing fraction indicates how closely atoms pack in a unit cell. You can calculate the diamond packing density of a material with some material parameters and ...
Either anaerobic or aerobic methods can be used; however, the high strength of these wastes, in terms of BOD5, TSS, and FOG, make them particularly well suited to anaerobic treatment. The elevated temperature of these wastewaters is also a factor. Higher temperatures decrease the oxygen ...
Introduction of an adhesion factor to cube in cube models and its effect on calculated moduli of particulate composites Article Open access 28 September 2022 VOX model: application of voxel-based packing algorithm on cementitious composites with 3D irregular-shape particles Article 29 June 2020 Re...
First, we will briefly introduce electrochemical energy storage materials in terms of their typical crystal structure, classification, and basic energy storage mechanism. Next, we will propose the concept of crystal packing factor (PF) and introduce its origination and successful application in relation...

Initially, 918 unique protein crystal structures were selected from the protein data bank (RCSB-PDB) [54] with a maximum R factor of 20% and a resolution cutoff of 2.0 Å. Upon sequence alignment of any two proteins from the database, in no case was their sequence identity greater than...
If the nuclear radius is on the order of 10-15 m and the factor q2/(4pi epsilon 0) is 1.5 times 10-9; eV m, what is the maximum value, in MeV, of the energy barrier to bring two nuclei that ...
