Techno-economic assessment of bioleaching for metallurgical by-products

Journal of Environmental Management
This study focused on the economic feasibility of two potential industrial-scale bioleaching technologies for metal recovery from specific metallurgical by-products, mainly basic oxygen steelmaking dust (BOS-D) and goethite. The investigation compared two bioleaching scaling technology configurations, including an aerated bioreactor and an aerated and ...

Enhancing All‐Solid‐State Batteries Performance Through Thickness Control and Surface Passivation of Thermally Evaporated Lithium Metal Anodes

Advanced Science, EarlyView.
This study demonstrates that thermally evaporated lithium anodes combined with LiF passivation provide a high‐performance thin anode design for next‐generation ASSBs. This approach increases the critical current density from 1.6 to 2.6 mA cm−2, enabling full cells to achieve over 500 and 300 cycles at 1.5 and 3 mA cm−2, respectively, outperforming even

Water pricing in Ireland: a techno-economic and political assessment [PDF]

International Journal of Environmental Studies, 2012
Ireland is one of a very small number of countries in the world which does not charge for domestic drinking water supply. Recent developments have indicated that the reintroduction of domestic charges in Ireland is being planned. Ireland has a daily average water usage per person of around 150 litres and an increasing demand for clean water reserves ...

Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures

Advanced Science, EarlyView.
Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

Ion Superhighways in a Hierarchical Polymer‐Ceramic Membrane Enable Rapid and Selective Lithium Extraction

Advanced Science, EarlyView.
A flexible PDMS‐LATP polymer‐ceramic membrane creates lithium‐ion “superhighways” for rapid and selective extraction from complex brines. The amorphous PDMS matrix suppresses nonselective leakage and stabilizes the ceramic network, while LATP provides preferential Li+ conduction.

Techno-economic evaluation of CO₂-EOR in the North Sea [PDF]

, 2015
CO2-EOR is a possible means to produce incremental oil from active oil fields. In the ongoing climate change debate, it is also welcomed as a business case for geological storage of CO2 (CO2 Capture and Storage, CCS).
