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

open access: yesEnergies
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-

Strong Fully Reprocessable Engineered Wood Composites

open access: yesAdvanced Materials, EarlyView.
Engineering a hyperbranched adhesive with complementary imine‐bond and hydrogen‐bond networks, combining it with wood particles to fabricate the wood composite (WP/HTP) under mild hot‐pressing conditions. The WP/HTP exhibits 100% mechanical strength recovery after three cycles of reprocessing, and the reprocessed modulus of rupture (MOR) and modulus of

From Dark Photocatalysis to Photobattery‐Type Operation: A Re‐Functionalized Ti‐MOF for Solar Energy Storage

open access: yesAdvanced Materials, EarlyView.
ReCl47‐bpy is developed as a solar‐rechargeable, Re‐functionalized two‐dimensional metal–organic framework (MOF) for light‐driven charge storage and dark utilization. Re–bipyridine sites stabilize photoinduced electrons, enabling two complementary configurations: a MOF suspension for long‐lived charge retention and dark H2 evolution, and a spin‐coated ...
