A novel process to remove carbonates from lithium-bearing sedimentary claystones
Background
Climate change solutions rely on clean energy, with electric vehicles playing a crucial role in reducing greenhouse gas emissions. However, the sustainable extraction of battery materials, particularly lithium, remains challenging. Traditional extraction methods from mineral ores and brine deposits require high amounts of acid and produce...

Deep Foundation Porewater Pressure Dissipater
Background
Porewater pressure, or the pressure of groundwater held within soil, rock, or gaps between particles, is an important factor in determining the stress state of soil. If the porewater pressure is increased to equal the applied soil effective stress, the soil may lose its strength and stiffness, and act more like a liquid, in a process called...

Method and Loading Module to Mechanically Increase Pile/Drilled Shaft End Bearing Stiffness
Background
Drilled shafts are deep foundation elements constructed in soil to resist compressive, uplift and lateral loads. This process involves drilling a hole to a design depth, and filling the hole with reinforcing steel and concrete. Tip resistance is not usually accounted for when estimating the overall capacity of drilled shafts and bored piles...
