Selective hydrogenation of nitrostyrenes is a great challenge due to the competitive activation of the nitro groups (─NO2) and carbon–carbon (C═C) double bonds. Photocatalysis has emerged as an alternative to thermocatalysis for the selective hydrogenation reaction, bypassing the precious metal costs and harsh conditions. Herein, two crystalline phases of layered ternary sulfide Cu2WS4, that is, body‐centered...
The structural coexistence of dual rigid and mobile sublattices in superionic Argyrodites yields ultralow lattice thermal conductivity along with decent electrical and ionic conductivities and therefore attracts intense interest for batteries, fuel cells, and thermoelectric applications. However, a comprehensive understanding of their underlying lattice and diffusive dynamics in terms of the interplay...
Solid Immersion Lens
In article number 2207596, Zushun Xu, Jing Zeng, Wen Fan, and co‐workers report a TiO2 nanoparticle‐assembled solid immersion lens (SIL) with excellent transparency, high refractive index and easy‐to‐handle size. This TiO2 SIL can provide a fast, wide‐field, real‐time, non‐destructive and low‐cost solution for improving the quality of optical microscopic observation of various...
Super‐resolution optical imaging techniques can break the optical diffraction limit, thus providing unique opportunities to visualize the microscopic world at the nanoscale. Although near‐field optical microscopy techniques have been proven to achieve significantly improved imaging resolution, most near‐field approaches still suffer from a narrow field of view (FOV) or difficulty in obtaining wide‐field...
As new 2D layered nanomaterials, Bi2O2Se nanoplates have unique semiconducting properties that can benefit biomedical applications. Herein, a facile top‐down approach for the synthesis of Bi2O2Se quantum dots (QDs) in a solution is described. The Bi2O2Se QDs with a size of 3.8 nm and thickness of 1.9 nm exhibit a high photothermal conversion coefficient of 35.7% and good photothermal stability. In...
Two‐dimensional Bi2O2Se quantum dots (QDs) are synthesized by a facile top‐down approach in article number 1905208 by Yue Chen, Zhenyou Jiang, Jundong Shao, an co‐workers. Boasting large photothermal conversion efficiency and excellent photoacoustic performance as well as suitable biodegradability, the Bi2O2Se QDs facilitate photoacoustic imaging of whole tumors in photothermal cancer therapy. The...
Bimodal imaging with fluorescence in the second near infrared window (NIR‐II) and positron emission tomography (PET) has important significance for tumor diagnosis and management because of complementary advantages. It remains challenging to develop NIR‐II/PET bimodal probes with high fluorescent brightness. Herein, bioinspired nanomaterials (melanin dot, mesoporous silica nanoparticle, and supported...
Cadmium‐free thick‐shelled InP/ZnSeS/ZnS quantum dot (QD) was synthesized using the heating‐up approach. This quantum dots was used in inverted quantum dots light emitting diode (QLED) devices. The brightness of the inverted QLED device can reach a brightness of over 10 000 cd m−2, low turn‐on voltage (2.2 V), and high power efficiency (4.32 lm W−1).
