, 2023 This chapter provides information on the definition, brief history, classification, essential properties, and new developments of rocket propellants. A rocket is just a chamber that holds pressurized gas. A narrow aperture located at one extremity of the chamber permits the gas to be released, generating a force that pushes the rocket in ...

A Bambusuril Receptor Binds Charge Diffuse Anions in Water at Picomolar Concentrations
Angewandte Chemie, EarlyView.Synthesis of a bambusuril macrocycle with unprecedented binding affinity for several charge diffuse anions, including iodide, perchlorate, nitrate, and perrhenate, in neutral phosphate buffer is reported. The macrocycle exhibits selectivity for charge diffuse over charge dense anions exceeding seven orders of magnitude.
