Heterostructures endow electrochemical hybrids with promising energy storage properties owing to synergistic effects and interfacial interaction. However, developing a facile but effective approach to maximize interface effects is crucial but challenging. Herein, a bimetallic selenide heterostructure is realized in a confined carbon network via an in situ electrochemical strategy to induce highly active and stable electrode architecture. The dynamically formed heterostructures upon repeated delithiation/lithiation process not only yield abundant interconnected SnSe2/FeSe2 heterojunctions with continuous channels for ion/electron transfer but maintain excellent conversion reversibility. Serving as anode for lithium storage, the SnSe2/FeSe2@C framework enables a high discharging capacity of 1781.9 mAh g−1 at 0.5 A g−1 after 500 cycles and superior cycling stability (no capacity fade after 1200 cycles at 2 A g−1). This study can guide future design protocols for interface engineering through the formation of dynamic channels of conversion reaction kinetics for potential applications in high‐performance electrodes.

Non‐invasive and rapid imaging technique at subcellular resolution is significantly important for multiple biological applications such as cell fate study. Label‐free refractive‐index (RI)‐based 3D tomographic imaging constitutes an excellent candidate for 3D imaging of cellular structures, but its full potential in long‐term spatiotemporal cell fate observation is locked due to the lack of an efficient integrated system. Here, a long‐term 3D RI imaging system incorporating a cutting‐edge white light diffraction phase microscopy module with spatiotemporal stability, and an acoustofluidic device to roll and culture single cells in a customized live cell culture chamber is reported. Using this system, 3D RI imaging experiments are conducted for 250 cells and demonstrate efficient cell identification with high accuracy. Importantly, long‐term and frequency‐on‐demand 3D RI imaging of K562 and MCF‐7 cancer cells reveal different characteristics during normal cell growth, drug‐induced cell apoptosis, and necrosis of drug‐treated cells. Overall, it is believed that the proposed 3D tomographic imaging technique opens up a new avenue for visualizing intracellular structures and will find many applications such as disease diagnosis and nanomedicine.

Flexible sensing technology has shown great application value in motion monitoring and physiological signal detection. In many applications, the detected signal has the characteristics of low strength and wide range, thus improving the sensitivity and measurement range of sensors becomes extremely important. An enhancing method based on folding structure is proposed in this paper. Through the analysis of folding structure characteristics, the theoretical model of the folding structure effect in flexible sensors is established and the enhancement effect of sensitivity and measurement range is testified through three kinds of commonly used sensors, resistive, capacitive, and inductive sensors. Through changing the number of folding units, the sensitivity and measurement range of sensors can achieve to be adjusted. Folding sensors also have good hysteresis and repeatability properties and show the great performance in the application of human motion monitoring, such as limbs bending and rotating, muscle powering. The proposed method has the characteristics of simple, economical, environment friendly, and widely suitable, meanwhile avoiding the complexity of other ways to improve performance. This work has potential to enhance the sensitivity and measurement range for more kinds of flexible sensors and is of great value to fabricate high performance sensors based on folding structure.

Key points A more general and continuous form of ‘A short history of SHELX’ phenomenon has been found. The Review of Particle Physics (RPP) series, which is called the bible in the particle physics field, is highly cited by other research papers. The RPP phenomenon is found in different journals and is affected by the host journal's impact factor and publication size. The RPP phenomenon provides a big or small, but temporary, boost to its host journal's impact factor. [ABSTRACT FROM AUTHOR]
