Summary: Metal clusters (MCs) are ultrafine metal nanoparticles with dimensions below 2 nm, serving as highly active catalysts but prone to aggregation. Cage-bearing materials, such as organic molecular cages and metal-organic cages, provide ideal confined templates for size-controlled synthesis of MCs without blocking active sites. These materials can be functionalized to obtain advanced composite catalysts, spatially organizing and compartmentalizing multiple active sites without mutual quenching. The synergy of multi-catalytic centers in cage-bearing nanocomposite catalysts enables accurate and efficient multistep cascade reactions, mimicking cell metabolism and biological synthesis. This review introduces confined synthetic methodologies for MCs enabled by cage materials and their applications in advanced catalysis.

Summary: Modifying the crystal structure of complex oxides by controlling their oxygen content has promising applications in energy conversion and chemical looping. Facilitating oxygen migration by compressive strain in La0.5Sr0.5CoOx films is reported, which shows a significant reduction in modulation duration and threshold voltage for reversible topotactic phase transformation (RTPT). The compressive strain results in a lower oxygen migration barrier and enhances the Co 3d band filling, suppressing the Co-O hybrid bond and facilitating oxygen migration. This work provides valuable insights and practical guidance for efficient oxygen migration in chemical looping and energy conversion.

Summary: The immobilization of powdery metal-organic-frameworks (MOFs) in a porous matrix is a promising approach for practical applications. In this study, porous alginate/ZIF-8 composite beads were synthesized using a green method, with ZIF-8 grown in alginate hydrogel beads and subsequently freeze-dried using only water as the reaction solvent. The hierarchically porous structure of the composite beads, consisting of macro- and meso-pores in the alginate matrix and micro-pores in the immobilized ZIF-8, enables enhanced adsorption properties. The adsorption performance of the composite beads towards water contaminants was evaluated using methylene blue as a probe molecule. The growth time of ZIF-8 was found to significantly influence the adsorption performance, with a maximum calculated adsorption capacity of 628.93 mg g(-1) at 298 K for ZIF-8@Alg30. The adsorption process followed the pseudo-second-order kinetic model and Langmuir isotherm model, and thermodynamic studies revealed that the process was spontaneous, endothermic, and irreversible.

Summary: In this paper, an Automatic Pruning Ratio Search (APRS) algorithm is proposed to find the layer-wise optimal pruning ratio within the deep reinforcement learning framework. A novel layer-level reward function is designed to address the coarse-granularity reward problem, and a computationally efficient method is used to evaluate the effect of pruning action on each single layer. Experimental results show that the proposed method can better reveal the underlying sparse sensitivities of different layers and achieve higher network accuracy after pruning compared to traditional methods.
