Podcast. Katrina Krämer discusses metal-organic frameworks: crystalline macromolecules comprised of metal ions or metal ion clusters ('nodes’) connected by ‘struts’ made from organic molecules. [10...
The Life Scientific, a new series of 30-minute programmes, begins this morning on Radio 4 at 9.00, repeated in the evening at 9.30. Each week Jim Al-Khalili, Professor of Physics at Surrey University, will...
Concerned primarily with the roles of both main group and transition metal ions in biological systems. Problems that arise from a deficiency or an excess of these metal ions are discussed together with the...
Looks at the sheet metal stamping press and its use in forming parts from sheet metal. Sheet metal stampings range from simple stamped parts to complex curved shapes. Discusses the differences between...
The concept of orbital angular momentum is introduced as an added property of the electron, and an energy state diagram of an alkali metal used to interpret the four spectral series observed for each metal.
Looks at sheet metal properties and die structure and operations. Explains stamping dies and the processes which form parts from sheet metal. Shows examples of different die operations such as shearing,...
Powder metallurgy is a technology used for producing a wide range of parts from metal powders. This programme shows how the process of near-net shape forming reduces or elimates the need for secondary...
Introduces sheet metal shearing and bending, exploring the many elements necessary for proper execution. Defines ‘knife clearance’, essential for proper shearing, and how it is modified for different...
Shows how, in combined field and laboratory exercises, students can determine levels of metal pollution.
Despite their scarcity, gold and silver were probably the first metals to be encountered by man while aluminium, the commonest metal at the surface of the earth, remained unused until the 19th century. These...
