CO₂ Reduction

In article number 2409910, Tokuhisa Kawawaki, Yuichi Negishi, and co-workers presents an insight into the precise design of Cu nanocluster catalysts for electrochemical CO₂ reduction reactions through atomic-scale ligand engineering, using two similar ligands. The obtained insights are crucial for designing Cu nanocluster catalysts that are both stable and highly selective, enhancing their efficacy for electrochemical CO₂ reduction.

Flavor contributes significantly to consumer preferences of cooked sweetpotato. Sugars largely drive the sweet taste, while the volatile organic compounds (VOCs), mainly classified as alcohols, aldehydes, ketones, and terpenes, provide characteristic aromas and influence the overall perception of flavor. In this paper, we review sweetpotato VOCs identified in the literature from 1980 to 2024 and discuss the efforts to understand how these compounds influence sensory perception and consumer preferences. Over 400 VOCs have been identified in cooked sweetpotato with 76 known to be aroma-active. Most of these aroma-active compounds are generated from Maillard reactions, Strecker, lipid and carotenoid degradation, or thermal release of terpenes from glycosidic bonds during cooking. Suggested mechanisms of formation of these aroma-active compounds are described. However, specific VOCs that are responsible for different aromas and flavors in cooked sweetpotatoes are yet to be fully characterized. There are significant opportunities to further identify the key predictors of aroma and flavor attributes in sweetpotato, which can be used to enhance the quality of existing varieties and develop new ones using a wide range of genetic tools. This review summarizes 44 years of research aimed at identifying key aroma compounds in cooked sweetpotato and provides a roadmap for future studies to guide breeders in developing high-quality, consumer-preferred varieties.

Accurate state estimation is paramount for the smooth operation and management of power systems, significantly contributing to their safety, stability, and reliability. However, the presence of channel noise and outliers stemming from phasor measurement units renders as the noise model a deviation from the Gaussian distribution. To mitigate this challenge, this paper introduces a parameterized analytical update cubature Kalman filter (PACKF) that significantly enhances estimation accuracy. Firstly, the updated analytical form of the state variable is derived, in which an unknown parameter is introduced. Secondly, the unknown parameter is approximated using fixed-point iteration, followed by the analytical computation of the required joint posterior probability density function (PDF). Finally, extensive simulations are conducted on the IEEE 39-bus test system, indicating that the proposed method commendable accuracy and efficiency across diverse scenarios.

Hydrogen Detection

By combining electron loss spectroscopy with in-situ gas TEM, hydrogen concentration is measured in a model system consisting of cubic palladium nanoparticles, with a lateral resolution down to 4 nm. The versatility of in-situ TEM allows to link together microstructure, hydrogen concentration and local strain, opening up a new chapter in hydrogen research.

The effect of the second relative on the microgalvanic corrosion of AZ31B alloy was studied. The behavior mechanism of the second phase in corrosion was discussed by adjusting the area ratio of the second phase by heat treatment. The experimental results show that the corrosion sensitivity of the second phase region and the grain boundary is higher, and the samples with larger second phase area show higher electrochemical activity and faster corrosion rate in the corrosive environment. It is found that the microcouple effect between the second phase and Mg matrix accelerates the dissolution rate of the alloy. This study provides theoretical support for further understanding and improving the corrosion resistance of AZ31B alloy.
