Are light alkali metals still metals under high pressure ?
The extended Hubbard Hamiltonian on a bcc lattice is studied at half-filling and for a finite hopping between next-nearest-neighbours, in mean-field approximation. An ionic insulating broken-symmetry phase is predicted for any hydrogenoid bcc solid in the density range 1.0 < r s < 2.6. The occurrence of an ionic phase would explain the failure to achieve hydrogen metallization at high pressures...
متن کاملMicrowave oven experiments with metals and light sources
Don’t put metal objects in the microwave’ is common safety advice. But why? Here we describe demonstration experiments involving placing household metallic objects in a microwave oven. These allow a better understanding of the interaction of microwaves with materials. Light bulbs and discharge lamps can also be used in instructive demonstrations. M This article features online multimedia enhanc...

15 صفحه اولHigh energy transmission of Al2O3 doped with light transition metals.
The transmission of transparent colored ceramics based on Al(2)O(3) doped with light transition metals is measured in the visible and infrared range. To clarify the role of the dopands we perform ab initio calculations. We discuss the electronic structure and present optical spectra obtained in the independent particle approximation. We argue that the gross spectral features of Co- and Ni-doped...
متن کاملMetals and Non-metals
Ductile: Substances that can be drawn into thin wires are called ductile. For example, most of the metals are ductile. Question 2: Why is sodium kept immersed in kerosene oil? Answer: Sodium and potassium are very reactive metals and and combine explosively with air as well as water. Hence, they catch fire if kept in open. Therefore, to prevent accidental fires and accidents, sodium is stored i...
