New mine for old - New mining technology improves mine development

New technologies are being employed in mining to fast-track mining production recovery processes from minimal capital investment. Michael Forrest talks to Chris Berlet, CEO of Columbia Metals,Toronto, Canada, about a technology that has revived the Lluvia de Oro mine in Sonora State, Mexico.

Functional films - Thin film technological breakthrough

A consequence of recent developments in microelectronics, optics and nanotechnology is a demand for wear resistant coatings and the enhanced functionality of conductive films. Thin films are key to the production of new materials and devices using this technology.

Secure Heritage - The Bath stone mines

Ashley Poulter, former Supervising Engineer at Scott Wilson Mining, UK talks about stabilising the Bath stone mines. He discusses some of the ideas for supporting and filling in underground mineshafts, such as concrete infilling, steel bracing and cogging.

The quest for new materials - Searching for lead-free piezoelectrics

Piezoelectric materials involve the generation of an electrical potential in response to applied mechanical pressure, and are used in the construction of as actuators and sensors. Researchers are seeking lead-free alternatives using a high-throughput combichem thin film approach.

Hidden depths - Depth profiling of organic thin films

Engineering thin organic films and producing layers of known composition is critical to industry. A range of techniques can be employed to determine the depth distribution and build a profile of elements within a material.
