Synergistic interface regulation for achieving fast kinetics and highly reversible zinc metal anodes.

Uncontrolled zinc dendrite growth and adverse side reactions at the Zn anode interface severely limit its practical application. Based on theoretical calculations, this study in situ constructs a functional interface (ICFI Zn) on the Zn anode surface, consisting of a surface-textured structure and a zinc-philic protective layer. Benefiting from the synergistic effect of ion regulation and atomic anchoring of this functional interface, the ICFI Zn anode achieves homogenised regulation of ion fluxes, facilitates ion transport kinetics, effectively suppresses side reactions and guides the deposition of dendrite-free Zn.

Development of a rat airway organoids model for studying chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) poses global health challenges owing to limited treatment options and high rates of morbidity and mortality. Airway organoids have recently become a valuable resource for the investigation of respiratory diseases. However, limited access to clinical tissue samples hinders the use of airway organoids to study COPD.

Evaluation of the Development, Implementation, Maintenance, and Impact of 3 Digital Surveillance Tools Deployed in Malawi During the COVID-19 Pandemic: Protocol for a Modified Delphi Expert Consensus Study.

Background: The COVID-19 pandemic has highlighted the importance of strengthening national monitoring systems to safeguard a globally connected society, especially those in low- and middle-income countries. Africa's rapid adoption of digital technological interventions created a new frontier of digital advancement during crises or pandemics. The use of digital tools for disease surveillance can assist with rapid outbreak identification and response, handling duties such as diagnosis, testing, contact tracing, and risk communication.
