Summary: Spinel ferrites are considered promising anode materials for LIBs due to their high theoretical specific capacities, but their practical application is hindered by low conductivity and volume expansion issues. This study successfully synthesized sub-10 nm CoFe2O4 nanoparticles with good dispersion through an aminolytic route, showing great potential as anode materials for LIBs. Additionally, this method can be extended to design other spinel ferrites for energy storage devices with superior performance.

Summary: Lithium-ion batteries (LIBs) are crucial for the electric vehicle (EV) industry, and LiNi1-x-yCoxMnyO2 (NCM) is the dominant cathode material used in EV LIBs. Due to the need for increased driving range, Ni content in NCM is maximized, but the resulting Ni-rich NCM is unstable. Doping with foreign elements has been explored as a strategy to overcome this instability, with over 46 elements considered and their effects on LIB performance investigated in numerous research articles. This comprehensive analysis of various doping elements and their impact on LIB performance provides valuable insights for the LIB industry and academia.

Summary: Nickel-rich layered oxides are the most promising cathode candidates for lithium-ion cells due to their high theoretical specific capacity. However, the higher nickel content leads to unwanted phase transitions and parasitic side reactions, causing capacity fading. Therefore, understanding the chemistry and structural behavior is essential for developing Ni-rich Lithium Nickel Cobalt Manganese oxide (NCM) cathode-based high-energy batteries. This review focuses on the challenges associated with Ni-rich NCM materials, surface modification strategies, and recent developments in coating techniques and their impact on degradation mechanisms.

Summary: The contamination of aquatic environments by pharmaceuticals used by modern societies, especially antibiotics, poses a serious threat to humans due to the potential for creating drug-resistant bacteria. This study reports a family of three isoreticular MOFs derived from natural amino acids that show high efficiency in removing a mixture of different families of antibiotics. A specific MOF, called MTV-MOF, prepared using equal percentages of L-serine and L-methionine, not only exhibits outstanding recyclability but also outperforms activated carbon. The successful removal performance of MTV-MOF is explained by single-crystal X-ray diffraction, highlighting the potential of MOFs as a promising alternative for capturing antibiotics from wastewater streams.

Summary: Since the emergence of metal-organic frameworks (MOFs), a wide range of exciting properties and applications have been reported, mainly due to their porous nature and rich host-guest chemistry. However, the potential rewards offered by other important features of MOFs have been largely unexplored. This feature outlines recent advances in using highly robust and crystalline oxamato- and oxamidato-based MOFs as reactors for the in situ preparation of well-defined catalytically active single atom catalysts (SACS), subnanometer metal nanoclusters (SNMCs), and supramolecular coordination complexes (SCCs).

Summary: The reaction of multi-bidentate oxamate-based copper(II) complexes with [Ni((i)Prtacn)Cl-2] complex has been studied. X-ray diffraction studies reveal the formation of trimetallic {CuNi2}, hexametallic {Cu2Ni4} and enneametallic {Cu3Ni6} complexes. The investigation of magnetic properties shows that Cu-Ni interactions through the oxamato bridge are in the expected range. The DFT calculations agree with the experimental results on the magnetic couplings of 1-3.

Summary: Understanding the host-guest chemistry in MOFs has great potential to develop novel porous materials with improved performances in fields such as heterogeneous catalysis. In this study, a family of three isoreticular MOFs derived from amino acids were synthesized and their catalytic activities in hemiketalization reactions were investigated. The results showed that a multivariate MOF prepared using equal percentages of amino acids exhibited the most efficient catalytic conversions. The good catalytic performance was attributed to the intrinsic heterogeneity of the multivariate MOF.

Summary: Covalent organic frameworks (COFs) have attracted great interest as a new type of crystalline porous polymers, but their preparation requires long reaction times. Microwave-assisted synthesis (MAS) offers a promising strategy for accelerating the reaction rate of COFs. In this review, we compile recent studies and experiments on the synthesis of COFs using MAS as an energy source, including imine, triazine, and other 2D COFs. We also summarize the research progress on 3D COFs, providing an overview of the chemical structures, synthesis parameters, and applications of the monomers and COFs in each article.

Summary: Functionalization of spin crossover porous coordination polymers (PCPs) with hydrogen-bonding active groups is an efficient strategy for the study of multifunctional materials. The interaction of guests with the host framework can improve the cooperativity of the spin crossover (SCO) and further enhance its properties. Comprehensive magneto-structural studies are still needed to understand the role of guests in the enhancement of the SCO properties.
