摘要 ：
The emerging data-intensive applications in optoelectronics are driving innovation toward the fused integration of sensing, memory, and computing to break through the restrictions of the von Neumann architecture. However, the present photodetectors with only optoelectronic conversion functions cannot satisfy the growing demands of the multifunctions required in single devices. Here, a novel route for the integration of non-volatile memory into a photodetector is proposed, with a WSe2/h-BN van der Waals heterostructure on a Si/SiO2 substrate to realize in-memory photodetection. This photodetector exhibits an ultrahigh readout photocurrent of 3.4 mu A and photoresponsivity of 337.8 A W-1 in the solar-blind wavelength region, together with an extended retention time of more than 10 years. Furthermore, the charge-storage-based non-volatile mechanism of h-BN/SiO2 is successfully proven through a novel analysis of in situ optoelectronic electron energy-loss spectroscopy. These results represent a leap forward to future applications and insightful mechanisms of in-memory photodetection.

摘要 ：
Inefficient charge separation and insufficient surface catalytic sites remain the main impediment in developing highly efficient and selective catalysts for CO2 photoreduction. Surface defects are effective, but their function is always constrained within the defect location. Herein, a desirable surface cation vacancy strategy is implemented to solve the above obstacles over Bi4Ti3O12 nanosheets. The surface Ti vacancy (V-Ti) creates an atomic-level charge transfer channel on the surface of Bi4Ti3O12, allowing a rapid transfer of photon-generated electrons from the V-Ti site of neighboring Ti and O atoms to CO2 molecules. More importantly, V-Ti activates neighboring Ti and O atoms, which allows them a stronger ability for enhancing CO2 adsorption and conversion. Thus, a convenient and swift charge transfer channel and activated near surface region are formed on the surface of Bi4Ti3O12, profoundly boosting the CO2 reduction process, as evidenced by experimental and theoretical results collectively. Without any sacrificial agents or cocatalysts, Bi4Ti3O12 with an optimal V-Ti concentration exhibits an outstanding CO production rate of 15.17 mu mol g(-1) h(-1), nearly 5 times higher than that of pristine Bi4Ti3O12. This work unfolds a new function of surface cation vacancies to substantially enhance CO2 photoreduction.

摘要 ：
Designing highly efficient photocatalysts is significantly important to degrade the harmful pollutions in water. In this study, photocatalyst of Fe3O4-ED-rGO with dissolved HPV was successfully prepared and electron microscopy characterization revealed that large number of single tungsten/vanadium atom oxide (ST/VAO) was homogeneously deposited on Fe3O4 nanoparticles in SMAO-MrGO-ED sample and occupied the bivalent Fe2+ sites. Meanwhile, phase analysis confirmed that the Fe3O4 nanocomposites were mostly conversed from the reducted Fe2O3 by the hydrolysis of rGO-ED-HPV. Such a highly dispersed monatomic adsorption on the bivalent Fe2+ of polycrystalline SMAO-MrGO-ED nanocomposite not only benefits for the visible light absorption from 2.7 eV to 2.10 eV, but also offers abundantly active sites to get the highest activity of 98.43% and 98.12% for ciprofloxacin (CF) and ibuprofen (IBF) photodegradation, respectively. All these discoveries give us a new insight to design the photocatalysts with high photodegradation efficiency, low cost, short reaction time and good reusability.

摘要 ：
The open-circuit voltage (V-OC) of cesium-based perovskite solar cells (Cs-PSCs) is severely limited by carrier recombination both in bulk and at the interface of the perovskite layer, which mainly roots in its elevated fabrication temperature. Enhancing the quality of perovskite film and optimizing the device structure are effective strategies to improve the performance of Cs-PSCs. Here, the V-OC is markedly promoted by constructing CsPbI3/Cs(1-x)DMA(x)PbI(3) bulk heterojunction (BHJ) structure, which was spontaneously formed by a precisely controlled spatially selective phase transition method. The perovskite BHJ structure not only facilitates the charge separation and collection process by enhancing the built-in potential but also obviously reduces the carrier recombination loss. Importantly, a maximum V-OC of 1.23 V was obtained as the V-OC deficit was 0.45 V, and the champion power conversion efficiency (PCE) reached 20.32% (certified PCE of 19.66%). Our finding indicates that junction engineering will be a new strategy for efficient perovskite devices.

摘要 ：
Lithium-rich layered oxides (LLOs) are prospective cathode materials for next-generation lithium-ion batteries (LIBs), but severe voltage decay and energy attenuation with cycling still hinder their practical applications. Herein, a series of full concentration gradient-tailored agglomerated-sphere LLOs are designed with linearly decreasing Mn and linearly increasing Ni and Co from the particle center to the surface. The gradient-tailored LLOs exhibit noticeably reduced voltage decay, enhanced rate performance, improved cycle stability, and thermal stability. Without any material modifications or electrolyte optimizations, the gradient-tailored LLO with medium-slope shows the best electrochemical performance, with a very low average voltage decay of 0.8 mV per cycle as well as a capacity retention of 88.4% within 200 cycles at 200 mA g-1 . These excellent findings are due to spinel structure suppression, electrochemical stress optimization, and Jahn-Teller effect inhibition. Further investigation shows that the gradient-tailored LLO reduces the thermal release percentage by as much as about 41% when the battery is charged to 4.4 V. This study provides an effective method to suppress the voltage decay of LLOs for further practical utilization in LIBs and also puts forward a bulk-structure design strategy to prepare better electrode materials for different rechargeable batteries.

摘要 ：
Metallic nanowires usually exhibit ultrahigh strength but suffered low ductility. Previous studies on pure metals suggested this strength-ductility trade-off results from limiting the dislocation activities. However, it is unclear whether such deformation model is valid for a solid solution alloy as well. Here, for the first time, the atomic-scale deformation process of AuCu nanowires with size of-16 nm was investigated in situ. The results show the NWs exhibit superplasticity (-185%) and high strengths (-2.98 GPa) at room temperature. It was discovered that superplasticity originates from continuous full dislocation nucleation and disappearance, as well as dislocation dipole formation and annihilation etc., which differ from the previous studies in pure metals. The observed full dislocation activities, also different from the ones in the previous studies, suggested that, as the size of the metals is below-100 nm, their deformation should be governed by partial dislocation and twinning.
