Photocatalytic Degradation of PFOA with Porous Lanthanoid Perovskites Nano Catalyst
Chemie Ingenieur Technik, EarlyView.Photocatalytic degradation of PFOA was studied using nickel‐ and lanthanide‐doped perovskites under UV–VIS irradiation. Catalyst characterization confirmed successful doping, with Ni/NdMnO3 showing the highest photocatalytic efficiency. Degradation occurred via C–C bond cleavage, forming transformation products PFHpA and PFHxA.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations
Deep Underground Science and Engineering, EarlyView.Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.
