Theory and Application of Zeta Potential in Papermaking.

open access: yesJAPAN TAPPI JOURNAL, 1998
A laboratory system has been developed to measure simultaneously the zeta potential, flocculation, and drainage of pulp and filler suspensions under hydrodynamic shear flow. The magnitude and trend of on-line streaming potential measurements correlated well with off-line electrophoresis measurements. The slight deviation between two measurements showed

NIR‐II Light‐Triggered Electron Flow Initiates Cuproptosis‐Centered Thermoelectric‐Immunotherapy for Breast Cancer

open access: yesAdvanced Science, EarlyView.
A NIR‐II light‐activatable thermoelectric nanoreactor converts surface‐bound Cu2+ into bioactive Cu+ via directed electron flow. This spatiotemporally controlled reduction triggers potent cuproptosis and immunogenic cell death, eradicating primary tumors and, together with aPD‐1 therapy, suppressing metastases while establishing durable immune memory ...
