Summary: A novel Fe trimer-based metal-organic framework (Fe-MOF) with high water stability and porosity was synthesized, showing enhanced catalytic activity and selectivity in the oxidation reaction. The Fe-MOF serves as a key support in the catalytic process, increasing catalytic activity up to three times and maintaining almost 100% selectivity within a short reaction time. The performance is closely related to the high surface area and suitable aperture size of the 1D channel in Fe-MOF structure.

Summary: In this work, a new strategy for ligand design is proposed, using piperazine and dihydrophenazine units as substitutes for benzene rings, via simple nucleophilic aromatic substitution reactions without using transition metal catalysts. 21 carboxylate-based ligands with varying sizes, shapes, and denticity and 15 linear di- and tetra-nitriles were successfully synthesized. Moreover, 16 structurally diverse MOFs with surface areas up to 3100 m(2) g(-1) were synthesized using these ligands as building blocks.

Summary: Exploring the effect of structural rigidity on porosity is crucial for designing hyper-cross-linked polymers. In this study, novel polymers with fine-tuned rigidity were constructed using a low-cost solvent knitting method. The porosity of these polymers is consistent with the rigidity of the building blocks, resulting in significantly enhanced BET surface areas. The best performances were achieved by HCP-SBF and HCP-TPM, showing high methane adsorption capacities and potential for onboard methane storage.

Summary: In this study, a new N-donor carboxylate linker, β-(3,4-pyridinedicarboximido)propionate (PyImPr), was used to synthesize Cd(PyImPr)(2)via two different methods, resulting in 2D or 3D supramolecular isomers. Crystal structure analysis revealed that both isomers consist of the same carboxylate bridged rod building block (RBB), and the ethylene moiety of PyImPr enabled structural flexibility. Furthermore, analysis of the Cambridge Structural Database (CSD) provided insights into the relative frequency of RBB topologies in related ML2 coordination networks.

Summary: Engineering design of metal organic frameworks (MOFs) for gas separation applications is a thriving field of investigation. We conducted a systematic theoretical study on derivatives of the closo-dodecaborate anion [B12H12](2-), which can serve as building blocks for MOFs, based on recent experimental studies. Amino functionalization was found to enhance the ability of selectively capturing carbon dioxide from its mixtures with other gases by inducing a polarization effect that favors localization of negative charges on the boron-cluster anion and provides a nucleophilic anchoring site for the carbon atom in carbon dioxide. This work suggests polar functionalization as an appealing strategy to optimize molecule discrimination ability through preferential adsorption.

Summary: In this study, label-free multiphoton microscopy (MPM) was used to acquire subcellular-resolution images of unstained breast cancer tissues. A deep-learning algorithm based on the generative adversarial network (GAN) was introduced to learn a representation using only MPM images without the histological grade information. The fusion of MPM and the GAN-based deep learning algorithm showed high classification accuracies for different tumor grades, suggesting its potential as a clinical tool for computer-aided intelligent pathological diagnosis of breast cancer.

Summary: Developing membranes with high gas separation performances for CO2 capture is desired. We synthesized a novel In(III)-MOF with chelating hydroxamate ligands, named SUM-9, which ensures structural stability, adding to the growing class of hydroxamate-based MOFs. SUM-9, along with its sister material SUM-1, was successfully incorporated into a series of Pebax 2533 based MMMs for CO2/N2 separation with controllable composition. Comparative study reveals that SUM-9 MMMs with only 1 wt% loading in Pebax 2533 exhibit significantly improved CO2 permeability (539 Barrer) and CO2/N2 selectivity (24.69) compared to pristine Pebax films and SUM-1 MMMs.

Summary: This study reveals that polyethylene (PE) and polyvinyl chloride (PVC) microplastics (MPs) have different impacts on the abundance and dissemination of antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in anaerobic sludge digestion. PVC MPs promote the acquisition of ARGs by human pathogen bacteria and functional microorganisms, while PE MPs do not. Horizontal gene flow (HGF) is observed to be a possible mechanism for new bacteria to acquire ARGs in MPs-stressed digester.

Summary: The design criteria for controlling antimicrobial performance of engineered nanomaterials (ENM) will lead to advances in various applications such as healthcare, food production, processing, preservation, and water treatment. This study investigates the antimicrobial activity of differently shaped silver nanoparticles (AgNPs) towards a model bacterium, Escherichia coli, and examines the influence of specific ENM properties, particularly nanoparticle shape, on the antimicrobial activity. The results show that the disc-shaped AgNPs exhibit the highest antimicrobial activity when using mass as the dose metric, while the cube-shaped AgNPs have the highest antimicrobial activity when using surface area and particle number as the dose metrics. This study highlights the importance of considering different dose metrics and the role of particle-specific factors in shaping the antimicrobial activity of ENMs.

Summary: Inspired by hydroxamate-based siderophores, the synthesis of a novel 2D Fe-hydroxamate metal-organic framework (MOF), SUM-31, is reported. This MOF, constructed from Fe(hydroxamate)(3) nodes and E-ethylenedihydroxamate linkers, features stacked 2D layers of honeycomb topology with interconnected channels for guest transportation and metal centre accessibility. The impressive chemical stability of SUM-31 in aqueous environments with a wide range of pH (1-12) and its redox-active Fe centres make it a promising electrochemical sensor for H2O2.
