Zwitterionic Polymer Coating Enabled Chronic Dopamine Sensing and Electrophysiology Recording in Free‐Moving Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...

Effects of sodium dodecyl sulfate on nano carbon black-filled cement paste: performance and microstructure

open access: yesJournal of Materials Research and Technology, 2023
The conductive potential of nano carbon black (NCB) in cement paste is restricted due to its tendency to agglomerate. To address this issue, sodium dodecyl sulfate (SDS) is proposed as a dispersant to enhance the performance of the nano carbon black ...

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Hydration process and rheological properties of SJP cement paste

open access: yesYantu gongcheng xuebao, 2017
Qwing to that the common cement paste used in the complex soil strata with wide steep seams and loose space cannot fill firmly and run along the gaps, a new type of SJP cement paste is developed, which has great initial fluidity and good groutability ...
