Intrinsic electrochemical activity modulation of MOF-derived C/N-NiCoMn-LDH/Ag electrode for low temperature hybrid supercapacitors

Xiaohui Guan et al.

Summary: By elaborately designing and providing a novel synthetic process, the composition and structure of C/N-NiCoMn-LDH/Ag (C/N-CNMA) can be delicately regulated, leading to improved conductivity and electrochemical activity of layered double hydroxides (LDHs), and thus superior charge storage capability and cycling stability at low temperatures.

Free-Standing Metal-Organic Framework Membranes Made by Solvent-Free Space-Confined Conversion for Efficient H2/CO2 Separation

Zhuangzhuang Gao et al.

Summary: In this study, a solvent-free space-confined conversion (SFSC) approach was used to fabricate a series of free-standing metal-organic framework (MOF) membranes. These membranes have a robust and unique structure, with large amounts of irregular-shaped micron-scale pore cavities and highly porous interlayers, resulting in satisfactory selectivities and exceptional permeances.

Programmable hierarchical photonic crystal arrays activated by post-hydrolysis for highly sensitive biochemical pH sensing

Donghui Kou et al.

Summary: Water is closely linked with our life and pH monitoring is of great significance to biochemistry, environment, and industry. A portable sensor with multilayered photonic crystal based pH sensors is proposed, which can change its color with different pH values and exhibit repeatable response to pH change with a short sensing time. The innovative dot-matrix sensor arrays with multiple sensing elements can provide distinctive color difference maps under diverse pH circumstances, and the color-based radar maps and PCA analysis greatly promote the detection accuracy and reliability.

Design of metal-organic frameworks for improving pseudo-solid-state magnesium-ion electrolytes: Open metal sites, isoreticular expansion, and framework topology

Yun Zheng et al.

Summary: The design criteria for metal-organic frameworks (MOFs) for pseudo-solid-state magnesium-ion conduction were established by evaluating the relationship between key characteristics and magnesium-ion conductivity. Open-metal sites and channel layouts play a crucial role in promoting magnesium-ion transport dynamics. X-ray absorption spectroscopy combined with other spectroscopic techniques were used to predict the chemical environment and composition of the electrolytes.

Extra highways for proton diffusion in TiO2@MIL-101-Cr/Nafion composite membranes with high single-cell performance

Xu Li et al.

Summary: Buffer layers of TiO2 nanoparticles on the surface of MIL-101-Cr were added to improve the performance of MOFs/Nafion proton exchanging membranes. Nafion composite membranes doped with TiO2@MIL-101-Cr were fabricated. The water uptake of the composite membranes increased while their swelling ratios decreased compared to pristine Nafion. The introduction of TiO2@MIL-101-Cr facilitated water diffusion and overall hydration of the composite membranes, resulting in a significant increase in proton conductivity.

Metal-Organic Frameworks-Based Nanoplatforms for the Theranostic Applications of Neurological Diseases

Huicong Niu et al.

Summary: Neurological diseases are a major cause of disability and death globally, with limited treatment options due to the unique characteristics of neural tissues and cells. The development of metal-organic frameworks (MOFs) as nanoplatforms offers potential for sensitive diagnosis and effective therapy. This article summarizes the challenges in neurotherapeutics, such as delayed diagnosis, blood brain barrier (BBB) limitations, off-target treatment, inflammatory stress, and nerve cell death. It highlights MOFs-based strategies for diagnosis (neuroimaging, biosensors) and therapy (enhanced BBB permeability, targeted treatment, inflammation/oxidative stress modulation, nerve cell regeneration). The article also discusses the challenges in translating this research to clinical applications, emphasizing the need for interdisciplinary studies.

Decoding Polymer Architecture Effect on Ion Clustering, Chain Dynamics, and Ionic Conductivity in Polymer Electrolytes

Recep Bakar et al.

Summary: This study systematically investigated the effects of polymer architecture and salt concentration on the properties of PEO-based polymer electrolytes. The results showed that branching of PEO can improve ion coordination and increase the ionic conductivity. Highly branched polymers exhibited significantly higher ionic conductivity compared to linear polymers. The addition of salt in the highly branched architectures resulted in accelerated yet similar monomeric friction coefficients, offering potential for enhancing battery performance.

Metal organic framework supported niobium pentoxide nanoparticles with exceptional catalytic effect on hydrogen storage behavior of MgH2

Liuting Zhang et al.

Summary: Nb2O5 nanoparticles with an average size of 10 nm supported on a rhombic dodecahedral MOF were synthesized by a hydrothermal reaction and calcination process. The prepared catalyst significantly improved the hydrogen storage behavior of MgH2. The addition of Nb2O5@MOF effectively enhanced the hydrogen desorption and absorption capacities of MgH2, with reduced activation energies. The composite exhibited good cyclic stability and the Nb2O5 particles were uniformly distributed on the surface of MgH2 matrix.

Ionic liquid-loaded metal-organic framework system for nanoionic device applications

Sang-Gyu Koh et al.

Summary: Metal-organic frameworks have attracted attention as functional materials due to their structural flexibility in designing materials with uniform nanopores. By studying the electrical properties of Cu-3(btc)(2), it was found that the absorbed solvent strongly influenced its properties. The highly insulating nanopores of Cu-3(btc)(2) allow liquids to be absorbed and used as solids.
