Summary: This study investigates CAU-10-H and CAU-10-CH3, two metal-organic frameworks (MOFs) with different functionalities, and reveals their water adsorption behavior and structural characteristics. CAU-10-H shows a steep increase in water uptake at around 18% relative humidity (RH%), while CAU-10-CH3 exhibits less steep water uptake at higher humidity values. The study highlights the importance of intermediate hydrophilicity sites in a hydrophobic structure for favorable water adsorption.

Summary: This study develops an efficient solar steam generation platform based on a hydrophilic metal-organic framework for producing drinkable water from seawater or wastewater. By coating Ti2O3 nanoparticles blended with poly(hydroxymethyl EDOT) (Ti2O3@PEDOT-OH) as photothermal conversion nanocomposites on synthesized CAU-10-H membranes, a transmembrane temperature gradient is created, optimizing water adsorption and desorption efficiency. The device with 13 μm thickness of CAU-10-H achieves the highest average evaporation rate of 2.20 kg.m- 2.h- 1 and an evaporation efficiency of 98%. Additionally, the ion concentrations of the produced water are lower than the drinkable water standard.

Summary: Highly compact metal-organic framework (MOF) membranes show promise in tackling challenging separation scenarios with industrial implications. Through a chemical self-conversion process, a continuous layer of layered double hydroxide (LDH) nanoflakes on an alumina support can transform into a MIL-53 membrane, resulting in highly compact architecture. This membrane can effectively dehydrate formic acid and acetic acid solutions and maintain stability in a corrosive chemical environment with a pH as low as 0.81. The energy consumption is significantly reduced compared to traditional distillation, saving up to 77%.

Summary: Pervaporation membrane reactors using carboxymethyl cellulose membranes modified with Zn-based metal organic frameworks (Zn(SEB), Zn(BIM), Zn(BDC)Si) were developed for simultaneous separation and reaction. The CMC/Zn(BIM) membranes showed optimal transport characteristics and were tested in a hybrid process of reaction + pervaporation. The application of the CMC/Zn(BIM) membrane led to a significant increase in the production of EtAc in the esterification reaction while decreasing the conversion of AcOH.

Summary: New functional materials, including mixed matrix membranes and MOF monoliths, demonstrate superior performance in gas separation and storage applications compared to traditional materials. However, simulation techniques currently available are unable to fully capture the spatial complexity exhibited by most engineered materials. This study introduces the MicMec implementation of a micromechanical model as a systematic coarse-graining approach to access larger length scales and characterize the mechanical properties of these materials. The results show that the micromechanical simulations can achieve time steps 2 to 3 orders of magnitude larger than atomistic simulations, while accurately capturing the macroscopic mechanical properties of the spatially disordered material. MicMec implementation can serve as a complementary tool to existing atomistic and coarse-grained software, facilitating the computational design of new materials for pressing applications.

Summary: A mesoporous silica-based solid acid with high surface area, large pore size, and moderate acid amount was synthesized through a one-step reverse-phase microemulsion method. The acid catalyst introduced 3-sulfopropyl as the acidic sites, resulting in a high surface silicon exposure and plenty of active groups. A novel strategy of waste to value was used to remove acetaldehyde from ethanol, converting it to a safer chemical of acetal with a pleasant odor. The remaining acetaldehyde could be controlled to a very low and safer level with a wide range of initial concentration.

Summary: In this study, a novel technique was developed to fabricate Zr-MOF membranes with excellent performance by concurrently regulating crystallographic orientation and thickness. Uniform triangular-shaped UiO-66 nanosheet seeds with a thickness of 40 nm were prepared using an anisotropic etching strategy. Through confined counter-diffusion-assisted epitaxial growth, highly (111)-oriented UiO-66 membranes with a thickness of 165 nm were achieved. These membranes exhibited unprecedented CO2 permeance (2070 GPU) and high CO2/N-2 selectivity (35.4), surpassing the performance limits of state-of-the-art polycrystalline MOF membranes. Additionally, highly (111)-oriented NH2-UiO-66 membranes with a thickness of 180 nm were prepared, showing superb H-2/CO2 separation performance with H-2 permeance of 1230 GPU and H-2/CO2 selectivity of 41.3.

Summary: A vacuum-assisted thermal bonding method was proposed for the covalent coupling of beta-cyclodextrin (CD-CSP), hexamethylene diisocyanate cross-linked beta-CD (HDI-CSP) and 3, 5-dimethylphenyl isocyanate modified beta-CD (DMPI-CSP) onto isocyanate silane modified silica gel. The method avoided side reactions under vacuum conditions and achieved optimal temperature and time of 160 degrees C and 3 h. The three CSPs exhibited good chromatographic performance, with CD-CSP achieving separation of all 7 flavanones enantiomers and HDI-CSP showing good separation performance for triazoles enantiomers with one chiral center.

Summary: A zeolitic octahedral metal oxide based on niobate (ZOMO-NbOx) with high acidity was synthesized and used as an efficient catalyst for the degradation of fluoroquinolone antibiotics under visible light. The presence of higher acidity promoted the adsorption of ciprofloxacin (CIP) on ZOMO-NbOx, expanding its light-absorbing range from UV to visible light through ligand to metal charge transfer. ZOMO-NbOx exhibited significantly higher catalytic activity compared to commercial Nb2O5, with a TOF value 53 times higher, and remained stable after multiple reuses. It also demonstrated good resistance to inorganic ions and humic acids, and effectively degraded CIP in various natural freshwater bodies. The intermediate products were identified and degradation pathways were proposed.
