Summary: The oxygen-evolving center in photosystem II plays a crucial role in the water splitting reaction of artificial photosynthesis. However, the lack of a precise chemical model has hindered the understanding of its structure-function relationship. Recent advances in synthesizing artificial clusters that closely mimic the oxygen-evolving center have provided an opportunity to study its structure-function relationship and design efficient catalysts for water splitting in artificial photosynthesis.

Summary: This study reports two synthetic Mn3XO4 oxygen clusters that mimic the structure and catalytic mechanism of the oxygen-evolving center (OEC) in photosynthesis. By analyzing the crystal structures, significant redox-induced structural changes were identified to occur on the mu(2)-oxide bridge. This research provides chemical insights into the reactivity of three different types of oxide bridges in the Mn4CaO5-cluster in PSII.

Summary: A simple cation exchange approach was used to produce Turing-type Ag2Se on CoSe2 nanobelts, resulting in a material highly effective in catalyzing the oxygen evolution reaction. The intrinsic OER activity correlates linearly with the length of Ag2Se-CoSe2 interfaces, indicating that these Turing-type interfaces are the active sites for OER. The excellent OER performance is attributed to the optimized adsorption energies for critical oxygen-containing intermediates at the unconventional interfaces, as shown by X-ray absorption and computational simulations.

Summary: This paper introduces the proposal of Extraterrestrial Artificial Photosynthesis (EAP) technology and its significance in manned space exploration, which converts CO2 into fuel and O-2 in extraterrestrial celestial environments to support deep space exploration by simulating the natural photosynthesis of green plants on Earth. The comparison with existing methods, discussion on material research progress, and future challenges of EAP technology are also explored in depth.

Summary: Zostera marina, a widespread seagrass, partially inactivated its oxygen-evolving complex in response to light exposure, but still maintained a normal carbon assimilation level. Through an in vivo study, it was found that the photosynthetic regulation of this seagrass can be verified at both proteome and physiology levels.

Summary: The study presents a new and promising strategy for in situ catalyst synthesis by adding Mn-II to CAN or KMnO4/CAN solution to form Mn-based catalysts for OER. Characterization of the catalysts revealed nano-sized particles catalyzing OER in the presence of CAN. The turnover frequencies for both catalysts were found to be 0.02 (mmolO2 /mol(Mn) • s).

Summary: Recent advances in plant biology have greatly enhanced our understanding of reactive oxygen species (ROS) as signaling molecules in the redox regulation of complex cellular processes. The redox regulation in photosynthesis plays a crucial role in maintaining photosynthesis homeostasis and plant productivity. The study also highlights the importance of plant responses to stress cues and genetic manipulation of disturbed redox status for balanced and enhanced photosynthetic efficiency and plant productivity.

Summary: Transition metal-based catalysts undergo surface reconstruction to generate active sites for high OER performance. This study proposes using self-reconstruction as an efficient strategy to develop novel OER catalysts by designing pre-catalysts with flexible components susceptible to OER conditions. By constructing NiFe-based LDHs intercalated with MoO42- anions and achieving complete ECSR into active NiFeOOH, the catalyst showed excellent OER performance and durability, indicating the potential of ECSR engineering in component-flexible precursors for developing highly active OER catalysts.

Summary: The study found significant differences in structure, photosynthetic activity, and protein expression profiles between bark and leaf chloroplasts in Salix matsudana. Bark chloroplasts exhibited lower grana stacks, higher starch levels, and lower oxygen evolution rates compared to leaf chloroplasts. Additionally, key proteins in photosynthesis light reactions were downregulated in bark chloroplasts, while proteins involved in dark reactions showed upregulation, suggesting a potential role of bark chloroplasts in fixing CO2 from malate decarboxylation.

Summary: The oxygen evolution reaction (OER) is a critical step in water splitting for hydrogen production, and understanding its mechanism is crucial for developing efficient OER electrocatalysts. However, the mechanism of OER, especially in a water-solvent environment, is still not well understood for the widely studied rutile Ru-based oxide. It is still debated whether the adsorbate evolving mechanism (AEM) competes with the lattice oxygen mechanism (LOM) for OER.
