Bismuth (Bi) is regarded as a promising anode material for potassium ion batteries (PIBs) due to its high theoretical capacity, but the huge volume expansion during potassiation and intrinsic low conductivity cause poor cycle stability and rate capability. Herein, a unique Bi nanoparticles/reduced graphene oxide (rGO) composite is fabricated by anchoring the Bi nanoparticles over the rGO substrate...
The emergence of amorphous 2D materials has opened up new avenue for materials science and nanotechnology in the recent years. Their unique disordered structure, excellent large‐area uniformity, and low fabrication cost make them important for various industrial applications. However, there have no reports on the amorphous MXene materials. In this work, the amorphous Ti2C–MXene (a‐Ti2C–MXene) model...
Photodynamic therapy (PDT), as a means of locally and rapidly inducing adipocyte death via light illumination, in combination with adipose browning induction, a more gradual and widespread effect that could transform white adipose tissue into thermogenic adipose tissue, manifests a promising approach to combat obesity. Herein, adipose‐targeting ultra‐small hybrid nanoparticles (Pep‐PPIX‐Baic NPs)...
Producing solar fuels over photocatalysts under light irradiation is a considerable way to alleviate energy crises and environmental pollution. To develop the yields of solar fuels, photocatalysts with broad light absorption, fast charge carrier migration, and abundant reaction sites need to be designed. Electrospun 1D nanofibers with large specific areas and high porosity have been widely used in...
The main obstacles for the commercial application of Lithium–Sulfur (Li–S) full batteries are the large volume change during charging/discharging process, the shuttle effect of lithium polysulfide (LiPS), sluggish redox kinetics, and the indisciplinable dendritic Li growth. Especially the overused of metal Li leads to the low utilization of active Li, which seriously drags down the actual energy density...
To achieve a high separation efficiency of photogenerated carriers in semiconductors, constructing high‐quality heterogeneous interfaces as charge flow highways is critical and challenging.

Sonodynamic therapy (SDT) is garnering considerable attention in cancer treatment due to its non‐invasive nature and the potential of spatiotemporal control. However, the high level of glutathione (GSH) in cancer cells can alleviate the SDT‐mediated ROS‐damages, resulting in a reduced SDT effect. Here, a two‐in‐one nano‐prodrug for photoacoustic imaging‐guided enhanced SDT against skin cancers is...
With the rapid development of nanotechnology, nanoparticles (NPs) are widely used in all fields of life. Nowadays, NPs have shown extraordinary antimicrobial activities and become one of the most popular strategies to combat antibiotic resistance. Whether they are equally effective in combating bacterial persistence, another important reason leading to antibiotic treatment failure, remains unknown...
The poor chemical miscibility between metal and organic materials usually leads to both structural and energetic mismatches at gold/organic interfaces, and thereby, high contact resistance of organic electronic devices. This study shows that the contact resistance of organic field‐effect transistors is significantly reduced by one order of magnitude, by reforming the contact interface between gold...
The commercialization of MXenes as anodes for lithium‐ion batteries is largely impeded by low initial coulombic efficiency (ICE) and unfavorable cycling stability, which are closely associated with defects such as Ti vacancies (VTi) in Ti3C2 MXenes.

As stated in the classic Kirchhoff's circuit laws, the total conductance of two parallel channels in an electronic circuit is the sum of the individual conductance. However, in molecular circuits, the quantum interference (QI) between the individual channels may lead to apparent invalidity of Kirchhoff's laws. Such an effect can be very significant in single‐molecule circuits consisting of partially...
