伪-Olefin co-monomers in linear low-density polyethylenes are known to alter/control the polymer properties. This information is essential for achieving specific/desired end use application in polymer processing industry. Knowledge, ther... GC Pandey - 《Process Control & Quality》 被引量: 1发表...
Calculate the linear atomic density in atoms per millimeter for the following directions in BCC vanadium, which has a lattice constant of 0.3039 nm. a. 100 b. 110 c. 111 Calculate the linear atomic density in atoms per millimeter for [ 110 ] directions in Bcc vanadium, which ...
Cleavage is the rapid propagation of a crack along a crystallographic plane which is usually of lower atomic density. When this plane is oriented well with respect to the loading direction, i.e. when a mode I crack can propagate within this plane, fracture occurs through the successive breaking...
The linear-response approach to density-functional calculations in the local-density approximation is more efficient than traditional supercell and dielectric matrix techniques for the calculation of physical properties such as phonon frequencies. We have implemented this approach within the framework of the...

The present work reports that density and linear attenuation coefficient of a material can be increased if its crystalline structure is changed from simple cubical structure to body centered cube (BCC) and faced centered cube (FCC). Results show that by changing the crystal structure of a ...

Due to the difference in definitions of the integrals to yield the topological content, this translates to the velocity being parallel to the charge density for n = 1 and perpendicular to it for n ≥ 2. This velocity will be normal to topological structures in the case of ...
The information density, here taken as the number of force components that are sizable, in supercells with only one or two displaced atoms such as the ones used in the direct approach is relatively low. Instead, one can consider general displacement patterns, involving many (or all) atoms in...
