Summary: A mesoporous MOF shell was synthesized on the surface of gold nanorods to capture single AuNRs for combinational phototherapy against solid tumors. The core-shell heterostructures combine a mesoporous structure and photoinduced singlet oxygen generation behavior with plasmonic photothermal conversion characteristic of AuNRs, enabling an efficient tumor treatment strategy. Applications beyond cancer therapy, such as plasmonic harvesting of light energy for catalytic reactions within MOFs and multifunctional nanocarriers for agricultural formulations, are also highlighted.

Summary: The integration of different types of metal-organic frameworks (MOFs) into hybrid MOF-on-MOF heterostructures has been extensively studied to increase the diversity of MOF-on-MOF hybrids. This study reports the structure regulation of MOF-on-MOF hybrids by controlling the nucleation and growth of guest MOFs. By using ZIF-90 as the host and ZIF-8 as the guest, binary ZIF-90@ZIF-8 complexes with different structures were successfully synthesized, enhancing the structural diversity of MOF-on-MOF materials.

Summary: A CO2-facilitated transport strategy is proposed to achieve the selective adsorption of CO2 over C2H2 by constructing core-shell composite structures using ionic liquid (IL) and metal-organic framework (MOF). The solution-diffusion mechanism for CO2 is revealed through density functional theory calculations and molecular dynamic simulations. This solution-based separation strategy shows superior performance in CO2/C2H2 separation and has the potential for practical production.

Summary: Encapsulation of active guest compounds inside metal-organic frameworks (MOFs) can lead to properties beyond those of bare MOFs and/or guest species. Core-shell composites show better accessibility to pores, optimal diffusion of substrate, and prevent aggregation and runoff of active guests, promoting synergistic effects. Advances in synthetic strategies and potential applications, such as environmental catalysis, gas separation, and sensing, are discussed in this review to promote new generations of MOFs based composites for energy-related applications.

Summary: This article presents a method to enhance the moisture resistance of fragile metal-organic frameworks (MOFs) by constructing a customized hydrophobic porous shell, NTU-COF, on MOF-5 using the Plug-Socket Anchoring strategy. It was found that the pore structure of MOF-5 was well preserved and could achieve complete CO2/N-2 separation even under humid conditions. Atomic resolution inspection of the interface between MOF-5 and NTU-COF revealed insights into the assembly mechanism of the core-shell structure.

Summary: Metal nanoparticles encapsulated in a MOF shell show remarkable catalytic properties, but commonly used capping agents decrease their reactivity. In this study, we developed a new method to prepare PVP-capped Au NPs@MOF-808 core-shell composites, and demonstrated for the first time that the capping PVP can be easily removed while maintaining the integrity of the MOF shell. The reactivity of the Au NPs@MOF-808 composites for selective oxidation reactions was significantly enhanced.

Summary: This study investigates two versions of reversed-phase/hydrophilic interaction mixed-mode core-shell stationary phases for high-performance liquid chromatography using porous organic polymers as the shell material. The researchers successfully obtained the SiO2@CHPCy-DB core-shell stationary phase by growing a porous shell on the surface of silica. The SiO2@CHPCy-DB exhibited reversed-phase/hydrophilic interaction mixed-mode with multiple retention mechanisms. Additionally, the role of the building blocks in porous organic polymers in regulating and improving separation was assessed by comparing the separation behavior of the homemade columns with a commercial column. The successful determination of trace analytes in complex samples using the SiO2@CHPCy-DB column demonstrates its potential.

Summary: This study presents a rhodium-based metal-organic framework (MOF) on-MOF difunctional core-shell nanoreactor as an artificial enzymatic NAD(P)H regeneration system. The UiO67 core captures rhodium molecules for catalyzing NAD(P)H regeneration, while the UiO66 shell specifically immobilizes His-tagged lactate dehydrogenase (LDH) and serves as a protection shield. The UiO67@Rh@UiO66@LDH exhibits good activity in NAD(P)H regeneration and maintains high activity even after 10 cycles.

Summary: This study compares the release of nitric oxide (NO) from unprocessed metal-organic frameworks (MOF) powders and MOF-polymer composites as catalysts. The results show that the rate of NO generation changes when a polymer composite is used as the catalyst, indicating that the findings for MOF powder catalysts may not always be applicable to MOF-polymer composites.

Summary: Through experiments on two pairs of isoreticular MOFs, it is revealed that the adaptability of shell-MOFs is the key factor controlling nucleation kinetics, and the degree of adaptability determines the sequence and facilitates the formation of a first triple-layered core-shell MOF by one-pot synthesis. The insights gained from this study will aid in the design and synthesis of other multi-shelled structures and expand their applications further.

Summary: Biodegradable plastic mulches (BDMs) have the potential to be an eco-friendly alternative to conventional plastic mulches in agriculture. However, their long-term impacts on soil ecosystems are still uncertain, and further research is needed. Incorporating BDMs into the soil may stimulate microbial activity, but there is also a risk of incomplete degradation and release of residual microplastics and additives.
