Coal Matrix Deformation and Pore Structure Change in High-Pressure Nitrogen Replacement of Methane

Energies, 2018
Coal matrix deformation is one of the main controlling factors for coal reservoir permeability changes in nitrogen foam fracturing. The characteristics and mechanism of coal matrix deformation during the process of adsorption/desorption were studied by ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Mathematical Model Establishment for the Multi-Scale Permeability of Coal Reservoirs and Its Engineering Significance

Energies
Permeability is a critical parameter governing the gas flow behavior of the coalbed methane (CBM) reservoir during the exploration and exploitation of CBM, as well as the geological storage of CO2 in the coalbeds. It is strongly associated with the multi-

Autonomous Folding of Soft Matter From Living Polymers

Advanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...

Swelling of Na-montmorillonite in the presence of dissolved gas molecules

Applied Clay Science
Various dissolved gases, such as CO2, H2, and CH4, may be present in the near-field geological repository due to metal corrosion or the degradation of organic waste. However, the influence of dissolved gases on the swelling behavior of bentonites, commonly used as backfill material, is still poorly understood.
