Researchers built a single-piece cellulose membrane with one hydrophobic and one superhydrophilic face that separates oil from water under gravity, retaining up to 95 percent of oil at fluxes above 3300 liters per square meter per hour. Article Title: Design of a…
A review in the Journal of Materials Science synthesizes recent advances in metal-organic-framework-derived metal oxides for chemiresistive VOC sensing, from synthesis strategies to practical applications. The appeal of these materials, according to the review, rests on three properties that translate…
A magnetically recoverable fungal biomass composite modified with copper ferrite nanoparticles and the MOF ZIF-67 removed up to 99.17 percent of cadmium from synthetic solutions and 70.2 to 82.6 percent from real industrial wastewaters.
Kinetic modeling of the adsorption data pointed to a specific mechanism. The pseudo-second-order kinetic model predicted the results well, with a coefficient of determination of 0.99926, indicating that surface-mediated interactions are crucial to the adsorption process. On the basis of these…
A cellulose nanocrystal-supported TiO2 nanocomposite degraded about 98.6% of the antibiotic ofloxacin under direct sunlight in laboratory tests, driven mainly by photogenerated holes. This support changed the optical properties of the catalyst in a way that matters for solar applications: the nanocomposite…
Covalent organic frameworks could help capture and break down nitrate pollution from waterways that causes algal blooms Covalent organic frameworks (COFs) can be used to rearrange water molecules, increasing the efficiency of the reduction of nitrate to ammonia, researchers in…
Scientists have released the Open DAC 2025 dataset, comprising nearly 60 million DFT calculations for gas adsorption in 15,000 metal–organic frameworks, to accelerate direct air capture research. Massive Dataset Accelerates Metal-Organic Framework Screening for Direct Air Capture To maximize the versatility and…
Researchers created multiphase strontium, magnesium, and barium oxide-carbon nanocomposites that adsorb malachite green with capacities up to 371.75 mg/g and remain reusable over five regeneration cycles.
Forced mechanical mixing of two high-entropy alloys produces a thermally stable ten-element amorphous interfacial phase only when the refractory constituent contains tantalum, while a vanadium substitution yields a nanocrystalline intermixed region with markedly different mechanical and magnetic behavior. Article Title:…
A bimetallic iron-manganese metal-organic framework with a 1:5 precursor ratio achieved the highest reported tetracycline hydrochloride adsorption capacity in the study, 338.96 mg g−1 at 318 K, through the combined action of pore structure and active sites. Tuned Iron-Manganese MOFs Boost Tetracycline Removal…
Materials full of holes by design: metal-organic and covalent organic frameworks, zeolites and other porous solids, and sorbents that harvest water and capture gases.
