He/ A3120J Local density approximation (atoms and molecules)/ He/elDensity matrices approximately N -representable by a correlated determinant wavefunction (CDWF) have been previously derived. For the case of helium it had been shown how to obtain these density matrices as density functionals. ...
athe X-rays used by crystallographers are approximately 0.5 to 1.5 angstroms in its wave length and is the right size to measure the distance between atoms in a molecule thus ,the orientation of unit cell. crystallographers使用的X-射线是大约0.5到1.5埃在它的波长并且是因而测量原子之间的距离的...

Such staggered exchange couplings and staggered magnetic fields arise naturally in certain compounds with (at least) two magnetic atoms per unit cell when coupled to uniform electric and magnetic fields, respectively34,35,36,37. See Fig. 1 for a schematic drawing of such a compound and Methods ...
How many procedures are indispensable for achieving excellence is yet to be definitively established. Improved training results may occur when complex cases are excluded, leading to a reduction in unnecessary difficulties.Amongst the complications that arise from sudden deafness, tinnitus is the most ...
Methane did burn in the well filled with the Atomergic alumina doped with Pd as palladium atoms on alumina near the hot compensator element became catalytically active. This example illustrates that, in addition to insulation and poison tolerance, a catalytic functionality can be built into an ...
Even though the entire process is not yet completely understood, it may be hypothesized that, when at higher temperatures the mercaptide molecules involved in such a type of supra-molecular organization are decomposed to produce metallic atoms, the latter diffuse within the columnar cavities, accumulat...
