Establishment of pore volume compressibility model for rocks and analysis of its influencing factors

Duankuai youqitian
The pore volume compressibility (Cp) for rocks is a key parameter for evaluating the dynamic reserves of oil and gas reservoirs. However, the experimental measurement of this parameter is time-consuming, while the empirical formula method has limited ...

Distinct Cleavage Trajectories Mediated by DNA and RNA Substrate in Argonaute From Methanocaldococcus Fervens

Advanced Science, EarlyView.
This study characterizes MfAgo, an enzyme exhibiting highly efficient DNA‐guided DNA and RNA cleavage capability. Precise RNA cleavage strictly requires dimerization to stabilize the PIWI‐loop region, while its robust DNA cleavage functions in a dimerization‐independent manner.

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.
