Summary: Organic electrode materials, known for their safety, environmental friendliness, and lower cost, have been used in aluminum-ion batteries (AIBs). However, the performance of AIBs using organics as cathode materials still lags behind inorganics, particularly in terms of battery capacity and voltage. Through experiments and theoretical calculations, BDTO was identified as the best performing cathode material among six organic compounds, with a high specific capacity of 236.8 mAh g-1 and 500 stable cycles. Additionally, the study confirmed the influence of ring structure and molecular structure on the properties of organic cathodes, providing valuable insights for the selection and design of rational organic cathode materials.

Summary: In this work, novel dual-electron-withdrawing group organic molecules are proposed as positive electrode materials of Al batteries. By introducing electron-withdrawing chloride groups and decreasing the benzene ring number, discharge voltage and conductivity of organic molecules are effectively enhanced. However, the solubility in the ionic liquid electrolyte increases, leading to poor cycling stability. The charge/discharge mechanism is independent of the molecule structure and heterogeneous chloride groups. The obtained 2Cl-NQ exhibits high energy density and stable discharge voltage.

Summary: A new sound localization model based on encoding temporal fluctuations within two hemispheric channels is capable of explaining a wide range of psychoacoustic experiments. The model suggests that binaural unmasking is achieved through the encoding of interaural differences in neuronal activity. By applying the model to numerous experiments, it successfully accounts for the majority of variance. This research is an important step towards a unified understanding of binaural unmasking and the encoding of interaural differences.

Summary: To functionalize C-H bonds of complex molecules and control the regioselectivity, various directing groups have been used. However, the installation and removal of these directing groups may limit the use of C-H activation in synthesis. A transient directing group strategy has emerged, utilizing an amine additive to achieve in situ formation of the directing group. This review presents the latest developments in this field from 2020 to 2023.

Summary: This paper investigates transient overvoltage issues caused by commutation failure (CF) in LCC-HVDC systems, and proposes constant reactive power control (CRPC) to suppress transient overvoltage. By controlling the reactive power consumed by the rectifier, the exchange of reactive power can be reduced, thus inhibiting transient overvoltage occurrences.

Summary: In this study, the problem of the explosive release of electrons and rapid deactivation of zero-valent aluminum (ZVAl) in normal water conditions was successfully addressed by modifying commercial ZVAl microparticles with a carbon layer. The modified material, Al@Alg-C600, showed the ability to remove a variety of organic and inorganic pollutants under a wide range of conditions, and it could be reused and reactivated. The unique carbon-wrapped clustered ZVAl structure of this material has great application potential.

Summary: This work investigates the transient angle stability of inverters equipped with the robust droop controller. The conditions on the control references to ensure the existence of a feasible post-disturbance operating point are derived. The post-disturbance equilibrium points are found and their stability properties are characterized. Furthermore, the stable and unstable manifolds of the surrounding unstable equilibrium points are calculated to accurately depict the attraction regions of the stable equilibrium points, offering an explanation to system transient stability. Finally, transient control considerations are provided to assist the inverter in riding through disturbances and maintaining its stability characteristics. It is demonstrated that transient angle stability is not a serious problem for droop controlled inverters with proper control settings.

Summary: Investigated the reactive ion beam finishing process of rapidly solidified aluminum (RSA) 501 using CF4 and N2 gasses to improve the surface roughness for UV optics. Found that surface modification can prevent grain orientation-dependent etching and adjusting ion incidence angle can reduce the protrusion of precipitates after UP-machining. Achieved a surface roughness value of Sq = 0.9 nm +/- 0.1 nm in the micro-roughness range using collimated ion beams with CF4 process gas at 40 degrees and 80 degrees angle of incidence.

Summary: This study investigates the effect of aluminum alloying on the static and transient thermomechanical behavior of SiMo ductile iron. Experimental methods were used to evaluate the high-temperature capability of different alloys. The results show that aluminum alloying improves the dimensional stability and oxidation protection of the material. The optimal level of aluminum alloying depends on the thermomechanical conditions of application.

Summary: Glycosylated natural products display biological activity but are deglycosylated by metabolic processes. CF2-derivatives of natural products are challenging to synthesize. Difluorinated molecules have unique conformational behavior due to changes in the glycosidic linkage. The site of glycosylation and substitution pattern on the flavonoid determine the conformational properties. Docking study showed potential for flavonoid-CF2-glycosides to retain a similar binding pose as the parent O-glycoside.
