Tectonic coal, formed after the intact coal being subjected to long-term intense squeezing,
shearing and deformation, is characterised by brittle or ductile damaged coal body, with the …

Nuclear magnetic resonance (NMR) has been applied widely and successfully in
conventional and unconventional reservoirs, and can be used to investigate petrophysical …

Liquid nitrogen (LN2) is an important means to improve the permeability of coal reservoirs.
The LN2 soaking method has a wide range of application prospects. However, not enough …

Eleven coal samples of different metamorphism are studied with regard to their pore
structures. Both low-pressure nitrogen gas adsorption (LP-N 2 GA) and scanning electron …

It is important to understand the disaster-causing mechanism of dried water-immersed coal
by investigating the influence of water immersion on the coal pore structure. In this study, low …

Microwave-assisted pyrolysis (MWAP) provides distinctive heating for the conversion of coal
into liquid fuels. This work investigated the effects of MWAP on the microstructure of …

Abstract Characterization of pore systems in subsurface systems is of great importance for
predicting the properties of rocks and classifying the subsurface systems. Geometric features …

Poly (lactic-co-glycolic acid)(PLGA) microspheres are a sustained-release drug delivery
system with several successful commercial products used for the treatment of a variety of …

Hydrogen is a clean fuel that can potentially revolutionize the energy supply chain and
decarbonize fuel consumption. However, a key hurdle that needs to be overcome before a …

Hypothesis Hydrogen geo-storage is considered as an option for large scale hydrogen
storage in a full-scale hydrogen economy. Among different types of subsurface formations …
