Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

Advanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Laboratory properties of mine tailings

Canadian Geotechnical Journal, 2001
A vast amount and variety of mine tailings are produced around the world each day. These mining wastes must be properly managed. To evaluate mine tailings disposal technology, the appropriate engineering properties of the tailings must be ascertained.

Exposures from mining and mine tailings

International Journal of Radiation Applications and Instrumentation. Part C. Radiation Physics and Chemistry, 1989
Abstract The mining, milling and tailings management of uranium ores results in environmental radiation exposures. This paper describes the sources of radioactive emissions to the environment associated with these activities, reviews the basic approach used to estimate the resultant radiation exposures and presents examples of typical uranium mind ...

Submarine mine tailings management

The Canadian Journal of Chemical Engineering, 2000
AbstractThe placement of mine tailings at depth in the marine environment is reviewed. This review considers first the engineering aspects of a pipeline system which transports tailings slurry from a process plant to the coast and then to a location at a depth of typically 200 m on the continental slope.

Towards mine tailings valorization: Recovery of critical materials from Chilean mine tailings

Journal of Cleaner Production, 2020
Abstract The mining industry produces large volumes of mine tailings – a mix of crushed rocks and process effluents from the processing of mineral ores. Mine tailings are a major environmental issue due to implications related to their handling and storage.

Pedogenesis in Mine Tailings

Proceedings of the International Conference on Mine Closure, 2006
Although mine tailings dams are man-made deposits it is anticipated that soil forming (pedogenic) processes are active e.g. translocation and transformation. These two main groups of soil forming processes are controlled by environmental factors, also called soil forming factors; parent material, climate, topography, and biota. In the case of man
