摘要 ：
In addition to the three well-known Ag-related precipitates (, X' and Z) in the Al-Cu-Mg-Ag alloys, Ag can also be involved in the formation of the as-cast second phases. However, the effect of Ag addition in Al-Cu-Mg-Ag alloys has not been completely studied and even the structure of the as-cast Agcontaining phases is still controversial. By employing the focused ion beam (FIB) combined with transmission electron microscopy (TEM) techniques and density functional theory (DFT) calculations, the formation mechanisms of the Ag-containing phases in the as-cast Al-Cu-Mg-Ag alloys have been investigated. The Ag-containing phases are a series of hexagonal C14-type Laves phases with continuously varying Ag concentrations, described as (Alx Cuy Ag1-x-y)(2) Mg. Moreover, the specific occupancy sites of the atoms in (Alx Cuy Ag1-x-y)(2) Mg were determined. The formation of the (Alx Cuy Ag1-x-y )2 Mg can be attributed to the stronger Ag-induced aggregation of solute atoms in the initial stage and the establishment of strong Ag-X (X = Al, Mg and Ag) bonding in the Ag-containing phases. Furthermore, our experiments have revealed the solidification sequence of Al-Cu-Mg-Ag alloys, and pointed out that (Alx Cu-y Ag1-x-y)(2) Mg is formed at a lower temperature (493.9 degrees C) through the reaction L Al-2 CuMg + (Alx Cu-y Ag1-x-y)(2) Mg. The study could have positive implications for refinement of the Al-Cu-Mg-Ag quaternary phase diagram and promote the composition-property design of novel aluminum alloys based on (Alx Cuy Ag1-x-y)(2) Mg in the future.

摘要 ：
The process of heterogeneous catalytic reaction under working conditions has long been considered a "black box", which is mainly because of the difficulties in directly characterizing the structural changes of catalysts at the atomic level during catalytic reactions. The development of in situ transmission electron mi-croscopy (TEM) techniques offers opportunities for introducing a realistic chem-ical reaction environment in TEM, making it possible to uncover the mystery of catalytic reactions. In this article, we present a comprehensive overview of the application of in situ TEM techniques in heterogeneous catalysis, highlighting its utility for observing gas-solid and liquid-solid reactions during thermal catal-ysis, electrocatalysis, and photocatalysis. in situ TEM has a unique advantage in revealing the complex structural changes of catalysts during chemical reactions. Revealing the real-time dynamic structure during reaction processes is crucial for understanding the intricate relationship between catalyst structure and its cata-lytic performance. Finally, we present a perspective on the future challenges and opportunities of in situ TEM in heterogeneous catalysis.

摘要 ：
An ??-Fe ??? ??-Fe phase transformation occurs in iron when the shock loading pressure exceeds 13 GPa, but all the ??-Fe will reverse back to ??-Fe during unloading, resulting in no residual ??-Fe in the unloaded samples. To prove the occurrence of this process, a series of microstructural characterization techniques were used to study the microstructures of shock-loaded iron, but hard to reach a consensus on the experimental results. Here, by using two conventional electron microscopy techniques, electron backscattered diffraction (EBSD) in scanning electron microscopy and selected area electron diffraction (SAED) in transmission electron microscopy, we reveal six novel phase transformation variants directly related to the reversible phase transformation. On this basis, the essential differences of microstructure between deformation area and phase transformation area are revealed. Further, we propose two fast and efficient methods which can identify the occurrence of the reversible phase transformation by EBSD and SAED, respectively. The universality of these methods has been verified in different shock loading experiments in iron.

摘要 ：
Metallic MoS2 (i.e., 1T-MoS2) is considered as the most promising precious-metal-free electrocatalyst with outstanding hydrogen evolution reaction (HER) performance in acidic media comparable to Pt. However, sluggish kinematics of HER in alkaline media and its inability for the oxygen evolution reaction (OER), hamper its development as bifunctional catalysts. The instability of 1T-MoS2 further impedes its applications for scaling up, calling an urgent need for simple synthesis to produce stable 1T-MoS2. In this work, the challenge of 1T-MoS2 synthesis is first addressed using a direct one-step hydrothermal method by adopting ascorbic acid. 1T-MoS2 with flower-like morphology is obtained, and transition metals (Ni, Co, Fe) are simultaneously doped into 1T-MoS2. Ni-1T-MoS2 achieves an enhanced bifunctional catalytic activity for both HER and OER in alkaline media, where the key role of Ni doping as single atom is proved to be essential for boosting HER/OER activity. Finally, a Ni-1T-MoS2||Ni-1T-MoS2 electrolyzer is fabricated, reaching a current density of 10 mA cm(-2) at an applied cell voltage of only 1.54 V for overall water splitting.

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.
