Lithium‐Ion Batteries
The effect of silicon particle size on its physical, chemical, and mechanochemical behaviors has been benchmarked via multiple lab‐ and synchrotron‐based characterizations. The significant differences caused by particle size in the composition transition, structure transition, particle pulverization, electrode expansion, and surface chemistry, are strongly related to their electrochemical...
High‐capacity silicon has been regarded as one of the most promising anodes for high‐energy lithium‐ion batteries. However, it suffers from severe volume expansion, particle pulverization, and repeated solid electrolyte interphase (SEI) growth, which leads to rapid electrochemical failure, while the particle size also plays key role here and its effects remain elusive. In this paper, through multiple‐physical,...
DNA‐based nanodevices equipped with localized modules have been promising probes for biomarker detection. Such devices heavily rely on the intramolecular hybridization reaction. However, there is a lack of mechanistic insights into this reaction that limits the sensing speed and sensitivity. A coarse‐grained model is utilized to simulate the intramolecular hybridization of localized DNA circuits (LDCs)...
Purposeful control of the highly active crystal planes is an effective strategy to improve the nanocrystalline catalytic activity. Therefore, Co2P nanocrystals with high exposure of (211) lattice plane loaded at 2D hexagonal V2O3 nanosheets (H‐Co2P‐V2O3) are designed via the control of morphology. After optimization, this H‐Co2P‐V2O3 boosts the redox kinetics of lithium polysulfides (LiPSs) in lithium–sulfur...
Osteomyelitis is considered as the most serious bone infection, which can lead to the bone destruction or fatal sepsis. Clinical treatments through frequent antibiotics administration and surgical debridement bring inevitable side effects including drug‐resistance and disfigurements. It is urgent to develop an antibiotics‐free and rapid strategy to treat osteomyelitis. Herein, a bifunctional sonosensitizer...
Bifunctional oxygen electrocatalyst: A metal–amino acid complex is developed to prepare high‐performance mesoporous carbon electrocatalyst for both oxygen reduction and oxygen evolution reactions. Such prepared catalyst can be used to assemble rechargeable zinc–air batteries with excellent durability. This work represents a new route toward low‐cost, highly active, and durable bifunctional electrocatalysts...
