Abstract: The present disclosure relates to sustainable and green polylactic acid-based membranes embedded with self-assembled positively and negatively charged multiwalled carbon nanotube/graphene oxide nanohybrids for the removal of organic and inorganic nutrients from wastewater, and methods of synthesis of the same. A positively charged multi-walled carbon nanotube/graphene oxide (f-MWCNT/GO) nanohybrid-based mixed matrix membrane can comprise a self-assembled multi-walled carbon nanotube and graphene oxide (f-MWCNT/GO) nanohybrid, and a polylactic acid (PLA) membrane matrix. The f-MWCNT/GO nanohybrid is integrated into the PLA membrane matrix to form the positively charged mixed matrix membrane. A negatively charged multi-walled carbon nanotubes (f-GO/MWCNTs-COOH) nanohybrid-based mixed matrix membrane can comprise a positively charged Graphene Oxide and negatively charged multi-walled carbon nanotube-COOH (f-GO/MWCNTs-COOH) nanohybrid, and a polylactic acid (PLA) membrane matrix. The f-GO/MWCNTs-COOH nanohybrid is integrated into the PLA membrane matrix to form the negatively charged mixed matrix membrane.

Abstract: A pH responsive film for indicating food freshness includes a protein, a polysaccharide, and anthocyanin, wherein the protein and the polysaccharide form a protein/polysaccharide matrix within the film, and wherein the film is sufficient to change color in response to a change in pH of the film. Methods of making and using the film are included in the present disclosure. Food preservation systems utilizing the film are also presented.

Abstract: A multi-functionalized NPG nanosheet can be used to form a 3D hierarchical multi-functionalized NPG membrane (NPG-pTD membrane) for use in oil/water separation. The NPG-pTD membrane includes a plurality of multi-functionalized NPG nanosheets in a stacked assembly with polyphenolic nanoparticles attached to the NPG nanosheets throughout the membrane. The NPG-pTD membrane can be formed via in-situ polymerization, which is vacuum assisted, such that the phenolic compounds from the multi-functionalized NPG nanosheet form the nanoparticles. Interlayer d-spacing between the adjacent nanosheets in the stacked assembly creates expansive and constricted channels, in addition to nanochannels provided by the pores in the nanosheets, such that the membrane has aquaporin-like properties. The NPG-pTD membrane exhibits high permeability and flux and superior selectivity for effective oil/water separation.

Abstract: A liquid desalination system is disclosed. The liquid desalination system includes a feed line having an inlet to receive liquid and an outlet to discharge the liquid. The liquid desalination system includes a magnet coupled to the feed line, the magnet to generate an oscillating magnetic field within the feed line and in opposition to the feed water flow. The removal of targeted ions can be achieved by manipulating the frequency and rate of the generated electromagnetic waves. The generated electromagnetic waves can be tuned to weaken the hydration bonds of that specific ion and facilitate its removal. The liquid desalination system generates an electric field across the feed line to enable the liquid to flow through the electric field. The electric field may attract sodium ions to a positive electrode and may attract chloride ions to a negative electrode, to desalinate the liquid in the feed line.
