Summary: The isomerism of a covalent organic framework (COF) greatly affects its electrochemiluminescence (ECL) performance. In this study, two isomeric COFs, TFPB-BD(OMe)(2)-H and TAPB-BD(OMe)(2)-H, were synthesized based on different imine linkages and conversion to the quinoline structure. Despite having the same composition and similar structures, the two COFs exhibited significant differences in photoelectrochemical and ECL fields. TFPB-BD(OMe)(2)-H showed a superior ECL emission compared to TAPB-BD(OMe)(2)-H due to stronger polar interaction and enhanced electron interactions.

Summary: This study presents high performance semi-transparent perovskite solar cells with bidirectional transparent electrodes, showing significantly improved power conversion efficiency compared to typical PSCs. The fabrication of a transparent IZTO cathode through a two-step sputtering process demonstrates the feasibility of producing high-quality transparent top cathodes for semi-transparent PSCs. These results suggest that the FTS-based two-step sputtering technique has great potential for mass production of smart windows in building-integrated photovoltaics.

Summary: The application of covalent organic frameworks (COFs) in electrochemiluminescence (ECL) for environmental monitoring shows great promise. This study developed a novel COF-based host-guest system to analyze nuclear contamination. By inserting an electron-withdrawing guest (tetracyanoquinodimethane) into the COF host, an efficient charge transport network was formed, triggering the ECL emission. This COF-based system provides a new material platform for constructing ECL luminophores and brings opportunities for the advancement of ECL technology.

Summary: Combustion, a product of human's ability to use fire, is still not fully understood. The complexity of factors such as the variety of carbon structures, surface structure, porosity, solid-gas nature, diffusion limitation and fundamental reaction steps complicates the investigation. This review provides a brief history of carbon combustion science and discusses the important aspects, with special attention given to limitations like diffusion. Kinetic control is rarely observed in carbon combustion. The literature review reveals that the reaction primarily occurs on defects on the carbon framework, making the reaction between oxygen and carbon an analytical tool for understanding novel materials.

Summary: External diffusion can be utilized to purify materials in a way that was thought to be impossible from a chemical reactivity perspective. By thermally oxidizing a mixture of graphite and carbon black under either outside total diffusion-limited regime or total diffusion-limited regime, it is possible to purify either graphite or carbon black. Controlled total diffusion-limited chemistry, with the introduction of geometrical selectivity, can be used as an engineering tool for materials purification, original synthesis, or creating asymmetry in a system. Several practical applications of these findings are mentioned.

Summary: This study reports the intercalation of iodine chains in highly crystalline multiwalled carbon nanotubes. The intercalation occurs between the concentric graphene shells instead of the central cavity. The filling is asymmetric with respect to the longitudinal axis of the nanotubes. Computational modelling and high-resolution transmission electron microscopy support the formation of asymmetric intershell channels and explain the opening of aligned intergraphene nanocavities.
