A Chinese research team developed an innovative device that skips CO₂ purification, cuts costs, and produces commercial-grade HCOOH directly from dilute emissions. The membrane-integrated electrolyzer concentrates CO2 to high levels for efficient conversion, producing a valuable liquid fuel and industrial chemical.
A team of scientists has developed a novel CO2-activated porous carbon adsorbent that selectively traps impurities while purifying target gases. The material achieves a record C3F6/C3F8 uptake ratio and produces 99.999% pure C3F8 at industrial scales.
Researchers developed a novel small-pore AlPO MS, DNL-17, using cutting-edge 3D electron diffraction technology. The new material features unique cages and a distinct stacking sequence, showing promise for selective adsorption in the separation of n-butane and isobutane.
Researchers at KAUST have developed a new type of carbon molecular sieve membrane that overcomes drawbacks of existing polymer membranes. The membrane, made from 6FDA-DMN, exhibits high rejection of small molecules and exceptional stability in various organic solvents.
Researchers at KAUST have developed a new class of oriented mixed-matrix metal-organic framework (MMMOF) membrane that selectively removes detrimental gases like H2S and CO2 from natural gas. The membrane demonstrates far better separation efficiency compared to conventional methods.
A new paradigm in atmospheric gas sensing has been achieved using a graphene sensor integrated with carbon molecular sieve functionality. The sensor demonstrates selective gas detection, including ammonia, at room temperature with a fast response time of seconds.
A team of researchers from the University of Delaware and Jilin University has synthesized the most stable crystalline porous material on record, a polyarylether-based covalent organic framework. This material can sift antibiotic residue out of water in a pH ranging from 1 to 13 and is stable up to 400 degrees Celsius.
A new discovery in chemistry could lead to more specific and desired forms of drugs, with the creation of chiral molecular sieves that can sort and create left- and right-handed molecules. This breakthrough has broad implications for pharmaceutical companies and may improve medications such as ibuprofen.
A new carbon-based membrane demonstrates a potentially disruptive technology in separating xylenes and similar organic compounds. The membrane uses an 'organic solvent reverse osmosis' process, reducing the energy required by conventional separation processes.
Researchers have developed a new way to create molecular sieves with aligned tunnel-like pores, enabling more efficient filtration and potential applications in water purification and optical components. The discovery opens doors to producing uniform fibers and even sheet-like materials with controlled properties.
