A Novel Anomaly Forecasting in Time‐Series Data: Feedback Connection between Forecasting and Detecting Algorithms with Applications to Power Systems

open access: yesAdvanced Intelligent Systems, EarlyView.
This article develops a novel feedback structure for machine learning‐based anomaly forecasting, by which both forecasting the future states and detecting the anomalies in these states can be achieved at the same time. The algorithm is shown to be applicable to power systems, verifying its effectiveness in detecting potential faults before they occur ...

Chemical Bonds Containing Hydrogen: Choices for Hydrogen Carriers and Catalysts

open access: yesAngewandte Chemie, EarlyView.
Hydrogen carriers utilizing B─H, C─H, N─H, and O─H bonds are evaluated for their potential in hydrogen storage and release. Key candidates such as methanol, ammonia, and formic acid are examined with a focus on critical factors influencing performance, including the nature of chemical bonds, reaction pathways, and catalytic processes.

Effect of Annulation Pattern on the Antiaromaticity of Thioether‐ and Sulfone‐Substituted Dinaphthopentalenes

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Benzannulation of dibenzopentalene leads to dinaphthopentalenes, of which, we synthesized the linear and anti‐isomer as thioethers with various substituents. Depending on the annulation pattern, their optoelectronic properties strongly differ. Of particular interest, is an increased antiaromaticity resulting from the anti‐annulation pattern, indicated ...

Dual‐Responsive Phosphorus‐Based Fluorescent Sensors: Synthesis and Selective Metal Sensing of Pyrazolyl Phosphine Oxides

open access: yesAngewandte Chemie, EarlyView.
Pyrazolyl phosphine oxides are shown to act as dual‐responsive fluorescent sensors, displaying a selective “turn‐off” fluorescence response for Fe3+ and a “turn‐on” response for Al3+. These systems serve as a new framework in the field of sensing materials based on main‐group elements such as phosphorus. Abstract Despite a wealth of previously reported

Thiophene Containing Polycyclic Aromatic Hydrocarbon Monkey Saddles

open access: yesAsian Journal of Organic Chemistry, Accepted Article.
Negatively curved chiral polycyclic aromatic hydrocarbons (PAHs) gained a lot of interest in research over the past years. By replacing phenyl against thiophene units in a monkey saddle shaped PAH, it was possible to further tune the photophysical and electrochemical properties as well as influence the racemization barrier of these three‐dimensional ...

Coupling of CuO@NiBiOx Catalyzed Glycerol Oxidation to Carbon Dioxide Reduction Reaction for Enhanced Energy Efficiency

open access: yesAngewandte Chemie, EarlyView.
A CuOx@NiBiOx core‐shell‐like catalyst is synthesized. Thanks to the Bi presence, the electronic structure of Ni is tuned, leading to better catalytic performance for glycerol oxidation compared to both CuOx and CuOx@NiOx catalysts. Additionally, coupling glycerol oxidation with CO2 reduction significantly reduces the operational voltage and the ...
