Summary: Metal-organic frameworks (MOFs) based materials have gained attention for developing high-performing supercapacitors. In this study, Ni3(HITP)2 MOF was successfully synthesized as an ultra-stable thin film electrode. The presence of the active layer was confirmed through various techniques. The formation of the film within the diffusion layer improved the electrochemical accessible surface area and minimized the low electrical conductivity of MOF based materials. This approach also enhanced the cycling stability, with 100% capacitance retention over 170,000 cycles at 0.9 V.

Summary: In this study, a series of continuous, low-thickness lanthanide-MIL-103 SURMOFs were fabricated using a layer-by-layer (LbL) approach in the liquid-phase epitaxy process. These Ln-SURMOFs exhibit highly sensitive thermometers with optical readout, which can be observed with the naked eye. High transmittance is achieved by precisely controlling the film thickness and quality of these Ln-SURMOF thermometers. Moreover, the thermal sensitivity in the temperature regime above 120 K can be improved by controlling the energy transfer between Tb(III) and Eu(III) through a sophisticated supramolecular architecture, namely MOF-on-MOF heteroepitaxy.

Summary: The availability of highly adaptable materials in suitable shapes is essential for fabricating next-generation MOF-based devices. In this study, thin films of a photoreactive benzophenone unit-containing metal-organic framework (MOF) were presented. Crystalline, oriented, and porous films of the zirconium-based bzpdc-MOF were prepared by direct growth on silicon or glass substrates. Through photochemical modification of the Zr-bzpdc-MOF films, various properties can be tuned by covalently attaching modifying agents, including small molecules and grafting-from polymerization reactions. Furthermore, 2D structuring and photo-writing of defined structures, such as micro-patterned MOF surfaces, are possible via a photolithographic approach.

Summary: A novel micromixer was fabricated via 3D printing with a 3D helical, threaded channel for enhanced mass transfer in an enzymatic cascade reaction converting CO2 to formic acid. Biocatalytic performance evaluations showed a 170% increase in formic acid yield with the addition of threaded channels, and the formic acid production rate was three times higher than a conventional bubble column. The modular system also allowed for the immobilization of different enzymes for sequential reactions and integration with a direct formic acid fuel cell for closed-loop energy generation.

Summary: This study reports neutron reflectometry (NR) studies of bio-mimetic polymer polydopamine (PDA) deposited from differing initial concentrations of precursor material dopamine hydrochloride. Confocal laser scanning microscopy (CLSM) and atomic force microscopy (AFM) were performed to understand the surface structure and mechanical differences of PDA. The results show that film structure and quality are heavily impacted by the initial concentration of dopamine hydrochloride and the polymerization time, indicating the highly customizable nature of PDA.

Summary: In this study, two-dimensional (2D) metalloporphyrin-based MOF Zn-2[TCPP(M)] films with abundant pi-pi interactions were successfully fabricated by the liquid-phase epitaxial layer-by-layer approach and assembled into photodetectors. The ZnTCPP(M)-based photodetectors exhibited an excellent photoresponse, and the metalloporphyrinic groups in ZnTCPP(M) played a significant role in modulating the photoresponse. The ZnTCPP(Zn) film-based device showed the best photodetection performance with high on/off ratio, responsivity, short rise/fall times, and large detectivity.
