The electrochemical nitrogen reduction reaction (NRR) is a promising strategy of nitrogen fixation into ammonia under ambient conditions. However, the development of electrochemical NRR is highly bottlenecked by the expensive noble metal catalysts. As a representative 2D nonmetallic material, black phosphorus (BP) has the valence electron structure similar to nitrogen, which can effectively adsorb...
A rolling-mediated cascade (RMC) amplification strategy is described for improved visualization of profiling glycans of mucin 1 (MUC 1) on cell surfaces. CdTe quantum dots (QDs) are used as fluorescent labels. The RMC based amplification allows even distinct glycoforms of MUC1 to be visualized on the surface of MCF-7 cell via an amplified Förster resonance energy transfer (FRET) imaging strategy that...
In article number 1802443, Xiao‐Dong Zhu, Yi‐Tao Liu, and co‐workers report unique solvothermal growth of TiO2 quantum dots (QDs) on ultrathin MXene nanosheets. Through remarkable synergies, the resulting TiO2 QDs@MXene nanohybrids exhibit significantly improved long‐term cyclability and rate capability as a sulfur host, disclosing a new opportunity toward fast and stable Li–S batteries.
Being conductive and flexible, 2D transition metal nitrides and carbides (MXenes) can serve in Li–S batteries as sulfur hosts to increase the conductivity and alleviate the volume expansion. However, the surface functional groups, such as OH and F, weaken the ability of bare MXenes in the chemisorption of polysulfides. Besides, they create numerous hydrogen bonds which make MXenes liable to restack,...
Although ligand fishing has been shown to be an efficient technique for the identification of bioactive components from complex mixtures such as natural products, it cannot be applied to biomedical image processing. Herein, a specific fluorescent ligand fishing combined with in situ imaging approach is presented for the identification of heat shock protein 90 (Hsp 90) inhibitors from complex matrixes,...
Black phosphorus (BP) is a rising star shining in the field of electrochemical energy storage because of its ability to react with up to three lithium to form a Li3P compound, giving a theoretical capacity as high as 2596mAhg−1. However, inherent embarrassments such as low electronic conductivity and huge volume expansion drastically deteriorate its ultimate electrochemical performances. Although...
