Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Design And Implementation of Simultaneous Soil Excavation of Adjacent Deep Foundation Pits

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The horizontal distance between two adjacent deep foundation pits in soft soil area is about twice the excavation depth. After the two foundation pits are designed and monitored throughout, the inclination data of each foundation pit is analyzed and it is found that the mutual influence is small.
