Herein, a stable and S-scheme Fe3O4@CuCr-LDH nanocomposite was synthesized used for the photocatalytic degradation of diethyl phthalate (DEP) through activation peroxymonosulfate (PMS). In comparison with pure Fe3O4, LDH, demonstrated significantly enhanced activity due to its charge-carrier migration mechanism. The prepared composite also magnetically recoverable from treated water which is fa...

We present a new concept for optimization under uncertainty: recoverable robustness. A solution is recovery robust if it can be recovered by limited means in all likely scenarios. Specializing the general concept to linear programming we can show that recoverable robustness combines the flexibility of stochastic programming with the tractability and performances guarantee of the classical robus...

Recently, the focus of fuel cell technologies has shifted from light-duty automotive to heavy-duty vehicle applications, which require improving stability membrane electrode assemblies (MEAs) at high constant potential. The hydrophilicity Pt makes it easy combine with water molecules and then oxidize potential, resulting in poor durability catalyst. In this work, an ionic liquid [BMIM][NTF2] wa...

We show that expander codes, when properly instantiated, are high-rate list-recoverable codes with linear-time list recovery algorithms. List recoverable codes have been useful recently in constructing efficiently listdecodable codes, as well as explicit constructions of matrices for compressive sensing and group testing. Previous list-recoverable codes with linear-time decoding algorithms have...
