Kinetic Model and Numerical Simulation of Microbial Growth, Migration, and Oil Displacement in Reservoir Porous Media.

Microbial enhanced oil recovery (MEOR) is a potential tertiary oil recovery method. However, past research has failed to describe microbial growth and metabolism reasonably, especially quantification of reaction equations and operating parameters is still not clear. The present study investigated the ability of bacteria extracted from Ansai Oilfield for MEOR.

Tension promoted circular probe for highly selective microRNA detection and imaging.

The crucial role of miRNA in cell regulation and its connection with diverse human cancers as a tumor suppressor or an oncogenic fragment poses great demand for an accurate and rapid approach for highly efficient miRNA detection and imaging in live cells. However, the ability to selectively detect and image miRNA remains a significant challenge in biomedical fields. Herein, a sealed circular probe (CP) has been prepared with copper free click ligation.

Biocompatible anionic polyelectrolyte for improved liposome based gene transfection.

Cationic liposomes have been widely used as efficient gene carriers. However, the serious cytotoxicity caused by exposed positive charges restricts the further application of those kinds of gene vectors. Thus, it is challenging to develop biocompatiable non-positive charge carriers to achieve high gene transfection efficiencies.
