Facile and controllable synthesis of functional yolk@shell structured nanospheres with a tunable inner core (‘yolk') and mesoporous shell is highly desirable, yet it remains a great challenge. Herein, xx developed a strategy based on temperature‐regulated swelling and restricted asymmetric shrinkage of polydopamine (PDA) nanospheres, combined with heterogeneous interface self‐assembly growth. This...
High‐voltage lithium metal batteries (LMBs) are a promising high‐energy‐density energy storage system. However, their practical implementations are impeded by short lifespan due to uncontrolled lithium dendrite growth, narrow electrochemical stability window, and safety concerns of liquid electrolytes. Here, a porous composite aerogel is reported as the gel electrolyte (GE) matrix, made of metal–organic...
In article number 2003834, Xin Du, Tailin Xu, Xueji Zhang, and co‐workers present an NIR light‐driven carbon@silica nanomotor with semi‐yolk@spiky‐shell structure camouflaged with MCF‐7 cancer cell membrane, displaying efficient self‐thermophoretic propulsion due to the thermal gradient generated by asymmetrically spatial distribution, thus achieving enhanced synergistic photothermal and chemotherapy...
Cell adhesion of nanosystems is significant for efficient cellular uptake and drug delivery in cancer therapy. Herein, a near‐infrared (NIR) light‐driven biomimetic nanomotor is reported to achieve the improved cell adhesion and cellular uptake for synergistic photothermal and chemotherapy of breast cancer. The nanomotor is composed of carbon@silica (C@SiO2) with semi‐yolk@spiky‐shell structure, loaded...
A simple wet ball‐milling method for exfoliating pristine graphite to graphene nanosheets is proposed. The surfactant of cetyltrimethyl ammonium bromide is utilized to greatly improve the exfoliation efficiency of graphene nanosheets. Variation of the ball‐milling time is an efficient way to control the size and thickness of graphene nanosheets, as well as the level of edge defects. With an increase...
