The catalysts for low‐temperature selective catalytic reduction of NO with NH3 (NH3‐SCR) are highly desired due to the large demand in industrial furnaces. The characteristic of low‐temperature requires the catalyst with rich active sites especially the redox sites. Herein, the authors obtain oxygen defect‐rich β‐MnO2 from a crystal phase transformation process during air calcination, by which the...
The sensitivity and linearity are critical parameters that can preserve the high pressure‐resolution across a wide range and simplify the signal processing process of flexible tactile sensors. Although extensive micro‐structured dielectrics have been explored to improve the sensitivity of capacitive sensors, the attenuation of sensitivity with increasing pressure is yet to be fully resolved. Herein,...
Proton exchange membrane fuel cells (PEMFCs) are promising devices for clean power generation in fuel cell electric vehicles applications. The further request of high‐efficiency and cost competitive technology make high‐temperature proton exchange membranes utilizing phosphoric acid‐doped polybenzimidazole be favored because they can work well up to 180 °C without extra humidifier. However, they face...
Carbon dots (CDs) represent a recently emerged class of luminescent materials with a great potential for biomedical theranostics, and there are a lot of efforts to shift their absorption and emission toward deep‐red (DR) to near‐infrared (NIR) region falling in the biological transparency window. This review offers comprehensive insights into the synthesis strategies aimed to achieve this goal, and...
Inorganic nanomedicine has attracted increasing attentions in biomedical sciences due to their excellent biocompatibility and tunable, versatile functionality. However, the relatively poor accumulation and retention of these nanomedicines in targeted tissues have often hindered their clinical translation. Herein, highly efficient, targeted delivery, and in situ aggregation of ferrocene (Fc)‐capped...
Perovskite oxides are studied as electrocatalysts for oxygen evolution reactions (OER) because of their low cost, tunable structure, high stability, and good catalytic activity. However, there are two main challenges for most perovskite oxides to be efficient in OER, namely less active sites and low electrical conductivity, leading to limited catalytic performance. To overcome these intrinsic obstacles,...
2D materials have been interesting for applications into nanodevices due to their intriguing physical properties.
