abstract = {The selective and sustainable synthesis of epoxides remains a critical challenge in chemical industry, as conventional oxidation routes often rely on transition metals, hazardous oxidants, and energy-intensive conditions, resulting in poor atom economy and limited sustainability. Herein, we report a transition-metal-free photo-catalyst system capable of promoting olefin epoxidation under mild conditions. Poly(triazine imide) (PTI), a highly crystalline carbon nitride, achieves near-quantitative styrene conversion with good selectivity toward styrene oxide under visible-light irradiation, using molecular oxygen (O2) as the sole oxidant and without the need for stoichiometric oxidants, chemical additives and harsh conditions typical of traditional protocols. A comprehensive structural and optoelectronical characterization was performed to correlate catalytic performance with the intrinsic properties of the material. Furthermore, mechanistic investigations were conducted to identify the key reactive species involved in the reaction. In situ EPR spin-trapping experiments reveal the cooperative involvement of photogenerated charge carriers and radical superoxide (O2 center dot-), driving the selective epoxidation process and singlet oxygen as the responsible for the byproducts. Overall, these findings highlight PTI as an efficient metal-free photocatalyst for O2-driven olefin epoxidation and demonstrate the potential of crystalline poly(triazine imide) materials as promising platforms for sustainable oxidation processes.},

abstract = {Organic cations can directly contribute to the electronic structure in hybrid organic-inorganic (HOI) materials, resulting in the formation of charge transfer semiconductors. Systematic tuning of the band gap by varying the organic cation in HOI charge transfer semiconductors remains underexplored. Here, we report the synthesis and characterization of (phenH(2))SbCl5 (phenH(2) = 1,10-phenanthrolinium) and investigate how the extended pi-system influences optical properties compared to the previously reported (2,2-bpyH(2))SbCl5 (2,2-bpyH(2) = 2,2 '-bipyridinium). Both compounds feature tetrameric [Sb4Cl20](8-) units and exhibit charge-transfer band gaps. Diffuse-reflectance spectroscopy shows a red-shifted absorption onset for (phenH(2))SbCl5 relative to (2,2-bpyH(2))SbCl5. The band gap decreases from 2.6 eV in (2,2-bpyH(2))SbCl5 to 2.1 eV in (phenH(2))SbCl5, a reduction of \>0.4 eV. Density-functional theory (DFT) calculations indicate that this red-shift arises from increased contribution of the phenanthroline pi*-orbitals to the conduction band. This demonstrates that systematic variation of the organic cation's pi-conjugation can provide a strategy for band gap tuning in charge-transfer HOI antimony halides.},

abstract = {Balancing the strength and toughness of materials\<br /\> remains a long-standing core challenge in materials science. In this study, a novel design strategy for Al2O3/Mg interpenetrating phase composites (IPCs) is proposed. Al2O, ceramic scaffolds with two types of Split-P triply periodic minimal surface (TPMS) structures (shell-type and solid-type) were fabricated via stereolithography (SLA) and then infiltrated with AZ91D magnesium alloy using lost foam casting (LFC), and consequently, Al2O/Mg IPCs were successfully fabricated. In the proposed method, cocontinuous interpenetration of ceramic and metal phases is achieved, ultimately forming a dense interlocking structure with no interfacial delamination and a relative density exceeding 95%. Quasi-static compression tests and finite element simulations confirm that the as-built composites exhibit a compressive strength of up to 1875 MPa and a specific energy absorption of 11.18 J/g; among them, the solid-type IPC shows a slightly higher compressive strength, while the shell-type IPC demonstrates superior energy absorption performance. The excellent performance of the IPCs is attributed to the TPMS structure that effectively mitigates the local stress concentration prone to occur in traditional truss structures, along with the synergistic strengthening effect between ceramic and metal phases that substantially improves the plastic deformation capacity and energy dissipation efficiency of the composites. This study provides a new idea for the design and fabrication of high-strength and lightweight composites, which hold significant application potential in lightweight load-bearing and impact-resistant energy-absorbing fields.},
