A mean free path approach to the micro/nanochannel gas flows [PDF]

open access: yes, 2020
We investigate the gas flows near to solid surfaces in terms of the local spatial variation in the molecular mean free path (MFP). Molecular dynamics (MD) is the appropriate scientific tool for obtaining molecularly-accurate dynamic information in micro ...

Free electron gas in cavity quantum electrodynamics

open access: yesPhysical Review Research, 2022
Cavity modification of material properties and phenomena is a novel research field largely motivated by the advances in strong light-matter interactions. Despite this progress, exact solutions for extended systems strongly coupled to the photon field are

The main controlling factors on shale gas occurrence characteristics in deep and high-over mature shales: A case study of Silurian Longmaxi Formation in the Sichuan Basin, southern China

open access: yesEnergy Reports, 2022
Deep shales refer to the shales with buried depth greater than 3500 m. Yields of shale gases depend on the form of their occurrence at the depth, but the major controlling factors on shale gas occurrence state in deep high-over mature shales are poorly ...

Geological characteristics and resource potential of deep coalbed methane in Guizhou

open access: yesMeitan xuebao
Accelerating the exploration and development of deep ( > 1 000 m)coalbed methane (CBM) resources is an important way for the large-scale development of CBM and an important development direction in recent years. Guizhou Province is rich in CBM resources,

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
