AN attempt 1 to resolve misunderstandings regarding ionic-covalent bonding in solids ... zinc blende structure and in many other types of crystal, as well as in co-ordination complex molecules).

Ionic crystals generally possess isotropic and close-packed structures and are unsuitable for creating nano-spaces. In this work, “porous ionic crystals” will be constructed by the use of molecular ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

The lattice arrangement continues in three dimensions. This is why solid ionic compounds form crystals with regular shapes.

Researchers at Cornell have engineered a groundbreaking porous crystal using a unique fusion of macrocycle and molecular cage ...

The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b ...

THE modern theory of solids predicts that an electron can travel freely through the periodic potential field of a perfect crystal lattice provided that its energy lies within certain well-defined ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

The patent’s innovative doped sulfide material uses a cubic crystal unit cell, with nitrogen doping on one side to stabilize ...
