Summary: As data centers become the backbone of the digital world, there is a need to capture the flexibility potentials of geographically dispersed data centers for system operation. This paper proposes electricity-heat coordinated operation to capture the flexibility potential of data centers and designs an incentivized profit-sharing mechanism to motivate their flexibility provision. Case studies based on real-world datasets demonstrate that incorporating data centers at the system level can improve operation efficiency and facilitate renewable energy integration.

Summary: With the rapid development of information technology, the scale and quantity of internet data centers (IDCs) are expanding, leading to a significant impact on the electricity load and operational flexibility of active distribution networks (ADNs). Flexible dispatch strategies have been proposed to improve energy efficiency of IDCs and reduce voltage violation and feeder load imbalance in ADNs, providing high-quality power supply for IDCs.

Summary: The development of artificial mimics of natural enzymes using supramolecular strategies is a significant challenge in bioorganic and bioinorganic chemistry. In this study, amphiphilic supramolecular phosphatases were created through self-assembly of a bis(Zn2+-cyclen) complex in a two-phase solvent system. These complexes showed higher hydrolysis activity for mono(4-nitrophenyl)phosphate in the presence of K+ ions compared to other metal ions, indicating the potential for acceleration of hydrolysis reactions.

Summary: Controlling the localization/delocalization of radicals is crucial for functional materials. In this study, the authors synthesized and studied diruthenium (p-diethynylacene)diyl complexes and their monocationic radical species. They found that the energy gaps could be finely tuned by the acene rings in the bridging ligands, resulting in absorption maxima ranging from UV to NIR. The cationic species showed characteristic NIR bands attributed to charge resonance and pi-pi* transition bands, and the expansion of acene rings led to blue shifts of charge resonance bands and red shifts of pi-pi* transition bands.

Summary: In this study, density functional theory calculations were used to evaluate the influence of a dinuclear metal-metal interaction during aryl C-O bond reduction/defunctionalization catalyzed by a heterodinuclear Rh-Al complex. The calculations demonstrate the critical Rh-Al cooperative behavior necessary for aryl C-O bond activation and catalytic turnover. However, only the Rh metal center is involved in hydrosilane Si-H bond activation or B-B bond activation of B-2(pin)(2) to defunctionalize the substrate.
