But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.Some things we send into space fall back toward Earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit ...
Cage molecules made up of coronand systems with 12-30 ring atoms consisting of 3-5 bridged triazine rings in which the carbon atoms in adjacent rings are linked by chalcogen-chalcogen or chalcogen-metal-chalcogen bridging groups, optionally with complexed atoms or molecules in the coronand rings...
Matter-wave dualism is a fundamental concept in quantum physics. The observation of wave properties of heavy organic molecules can be used to approach the borderline between classical and quantum physics. Up to which mass and size do par... L Felix 被引量: 0发表: 2015年 Quantum interference ...
The knowledge of the parameters controlling the cluster growth allows the shift of the mean cluster size within the above given size range with reasonably narrow size distributions of the Gauss-type. The cluster size down to 10 Å in diameter is measured by electron microscopy; the existence ...
The present status of ab initio computations for atomic and molecular wave functions is analyzed in this paper, with special emphasis on the work done at the IBM Research Laboratory, San Jose. The Roothaan-Hartree-Fock method has been de... Clementi,Enrico - 《Ibm Journal of Research & Devel...
In preliminary unpublished research, they then identified a way to boost SIRT6 activity, which slowed all of these processes in ageing cells. When this is written up, it will be the first demonstration of SIRT6’s action in skin cells, says Pernodet, who hopes their findings might also be...
