Abstract: A periodic mesoporous organosilica (PMO) nanoparticle functionalized nanocomposite membrane (NCM) for membrane distillation, the NCM including: polymer fibers such as polyetherimide fibers aggregated into a matrix; and hydrophobic PMO nanoparticles disposed on the polymer fibers. The PMO nanoparticles include a framework connected by organic groups and pentafluorophenyl groups. Good membrane flux and anti-fouling was demonstrated. Membranes can be prepared by electrospinning.

Abstract: Composition comprising at least one graphene material and at least one metal. The metal can be in the form of nano particles as well as microflakes, including single crystal microflakes. The metal can be intercalated in the graphene sheets. The composition has high conductivity and flexibility. The composition can be made by a one-pot synthesis in which a graphene material precursor is converted to the graphene material, and the metal precursor is converted to the metal. A reducing solvent or dispersant such as NMP can be used. Devices made from the composition include a pressure sensor which has high sensitivity. Two two-dimension materials can be combined to form a hybrid material.

Abstract: The present disclosure provide processes of separating aromatic isomers; liquid-liquid extraction systems and processes; liquid-liquid extraction solvents; cucurbituril macrocycle selective for the extraction of aromatic isomers; related materials, methods, and systems; and the like. The process of separating aromatic isomers may include contacting an isomers solution including one or more aromatic isomers, with an aqueous solution including a cucurbituril macrocycle, to produce a first aqueous phase and a first organic phase, wherein the cucurbituril macrocycle is selective for the extraction of at least one of said aromatic isomers.

Abstract: Embodiments of the present disclosure describe a conjugate comprising a mesoporous nanoparticle having a plurality of pores, wherein the mesoporous nanoparticle is positively charged, wherein an active agent is disposed in the pore; and a plurality of metal nanoclusters, wherein the metal nanocluster has a negative charge, wherein a gate agent is attached to the metal nanocluster. Embodiments of the present disclosure also describe a method of using a conjugate comprising exposing a conjugate to microbes sufficient to release an active agent and treating the microbes with the released active agent. Embodiments of the present disclosure further describe a method of using a conjugate comprising exposing a conjugate to microbes and detecting a presence of the microbes.
