Helicobacter pylori (H. pylori) infection presents increasing challenges to antibiotic therapies in limited penetration through gastric mucus, multi‐drug resistance (MDR), biofilm formation, and intestinal microflora dysbiosis. To address these problems, herein, a mucus‐penetrating phototherapeutic nanomedicine (RLs@T780TG) against MDR H. pylori infection is engineered. The RLs@T780TG is assembled...
Atomic‐scale interface engineering is a prominent strategy to address the large volume expansions and sluggish redox kinetics for reinforcing K‐storage. Here, to accelerate charge transport and lower the activation energy, dual carbon‐modified interfacial regions are synthesized with high lattice‐matching degree, which is formed from a CoSe2/FeSe2 heterostructure coated onto hollow carbon fibers....
Mn‐based layered oxide is extensively investigated as a promising cathode material for potassium‐ion batteries due to its high theoretical capacity and natural abundance of manganese. However, the Jahn–Teller distortion caused by high‐spin Mn3+(t2g3eg1) destabilizes the host structure and reduces the cycling stability. Here, K0.02Na0.55Mn0.70Ni0.25Zn0.05O2 (denoted as KNMNO‐Z) is reported to inhibit...
Potassium‐ion battery represents a promising alternative of conventional lithium‐ion batteries in sustainable and grid‐scale energy storage. Among various anode materials, elemental phosphorus (P) has been actively pursued owing to the ideal natural abundance, theoretical capacity, and electrode potential. However, the sluggish redox kinetics of elemental P has hindered fast and deep potassiation...
This work reports a portable, origami‐type paper device with a plasmonic fluor‐labeled microneedle sensing module for the multiplexed quantification of anemia biomarkers in whole blood. Sequential steps, including serum separation, target enrichment, and multiplexed readout by a gel imager, are rapidly accomplished with the flexible and highly integrated device. The microneedle array enabled efficient...
