The controlled reaction of Na and Cs, two alkali metals of different ionic sizes and binding abilities, with sumanene (C H ) affords a novel type of organometallic sandwich [Cs(C H ) ] , which crystallized as a solvent-separated ion pair with a [Na(18-crown-6)(THF) ] cation (where THF=tetrahydrofuran). The unprecedented double concave encapsulation of a metal ion by two bowl-shaped sumanenyl anions in [Cs(C H ) ] was revealed crystallographically. Evaluation of bonding and energetics of the remarkable product was accomplished computationally (B2PLYP-D/TZVP/ZORA), providing insights into its formation.

Article Synopsis
- * Findings show that increased surface hydroxyl content enhances carbon dioxide (CO) adsorption affinity, with the wettability type significantly impacting CO displacement behavior and oil recovery efficiency.
- * The research concludes that oil-wet pores reduce CO-EOR efficiency, while certain pore structures can influence displacement speed, emphasizing the need to optimize wettability to improve recovery processes.

Article Synopsis
- * A study evaluated five patients who developed spinal deformities post-NB resection, using techniques like growing rods, spinal fusion, and casting, achieving significant improvement in their conditions.
- * It's recommended to monitor spinal deformities closely and start treatment within 6 months of diagnosis, tailoring the approach based on the patient's growth potential and skeletal maturity.
Multi-core few-mode fiber based on space division multiplexing technology is widely regarded as the primary solution to the optical communication capacity issue. However, the quality of the communication signal of the multi-core few-mode fiber depends on the degree of energy coupling between the cores. Thus, we propose a heterogeneous sixteen-core four-mode fiber that achieves low inter-core crosstalk, which first employs a combination of concave and convex double-type refractive index profiles.
