Article Abstract
Regulating both crystallographic orientation and thickness of titanium metal-organic framework (Ti-MOF) membranes remains a significant challenge. In this study, we pioneered the fabrication of uniform 29 nm thick NH-MIL-125 nanosheet seeds by employing crystallization kinetics modulation approach. Through innovating confined counter-diffusion-assisted epitaxial growth under single-mode microwave heating, a highly -oriented 80 nm thick NH-MIL-125 membrane was prepared. Significant reduction in thickness endowed the membrane with unprecedented H permeance (1350 GPU) along with considerable H/CO selectivity (19.1), exceeding the performance benchmarks of state-of-the-art NH-MIL-125 membranes.

Although heterogeneous photo-Fenton reactions on nanoparticulate iron oxides effectively degrade organic pollutants, the underlying surface mechanisms remain debated. Here, we demonstrate how these pathways are modulated by specific hematite crystal facets. To investigate the influence of particle surface structure, methylene blue (MB) adsorption and photodegradation kinetics are examined using facet-engineered hematite nanoparticles with distinct exposed facets.

Phase segregation remains one of the most critical challenges limiting the performance and long-term operational stability of wide-bandgap perovskite solar cells (PSCs). This issue is especially pronounced in 1.84 eV wide-bandgap (WBG) perovskites, where severe halide phase segregation leads to compositional heterogeneity and accelerated device degradation.

Background: Cystic fibrosis (CF) is a systemic disease which primarily affects pulmonary system, but also extends to different important organs to cause multitude of associated diseases, leading to rise in rate of morbidity and mortality. The present investigation is focused on the development and optimization of SLN (Solid Lipid Nanoparticles) formulation of IVF (Ivacaftor) for effective treatment of cystic fibrosis.
Methods: IVF-SLN was formulated with the help of homogenization and ultrasonication methods by incorporating Labrasol as liquid lipid, Cetyl palmitate as solid lipid and Polysorbate 20 as the surfactant.

High-nickel layered oxide LiNiCoMnO (NCM, ≥ 0.8) materials are considered optimal cathodes for lithium-ion power batteries owing to their high energy density, commendable cycling performance, and cost-effectiveness. However, structural collapse and interface instability during cycling result in diminished cycling stability, significantly hindering their commercial viability.

Diamond and adamantane () share a -symmetric carbon skeleton, but converting to diamond has been challenging because it requires selective carbon-hydrogen (C-H) bond cleavage and monomer assembly into a diamond lattice. Our approach differs from the conventional high-temperature, high-pressure diamond syntheses. We electron-irradiated submicrocrystals at 80 to 200 kilo-electron volts and 100 to 296 kelvin in vacuum for tens of seconds.
