Molecular simulation of self-diffusion of CH4, H2O and CO2 in coal macromolecule

open access: yesMeikuang Anquan
In this paper, the self-diffusion coefficients (SDC) of CH4/CO2/H2O in coal molecules under different ensemble conditions and the effects of temperature and pressure are calculated by grand canonical Monte Carlo and molecular dynamics (MD) methods ...

Etiology, Diagnosis, and Treatment Strategy of Dental Therapy-related Subcutaneous Emphysema

open access: yesDental Hypotheses
Subcutaneous emphysema (SE) is defined as localized tissue swelling caused by gas entering subcutaneous tissue through a tissue gap. Although SE is usually a nonfatal and self-limiting disease, in severe cases, the gas may spread to the neck, mediastinum,

Impact of hydroxypropyl guar polymer on rheology and filtration properties of water-based drilling fluids

open access: yesPetroleum
Water-based drilling muds (WBM) are a very crucial component of the oil and gas industry; however, they often face challenges with inadequate rheological performance and excessive fluid loss. This paper introduces hydroxypropyl guar polymer (HPG) and fly
