Abstract: The present disclosure refers to a method of obtaining metal ions from a battery, the method comprising (i) adding fruit to a solvent to form a mixture; (ii) subjecting the mixture of step (i) to fermentation or heat treatment to obtain a leaching solution; and (iii) adding a crushed battery to the leaching solution to obtain a leachate comprising metal ions.

Abstract: The present invention, as disclosed herein, provides an isolated peptide, and a composition or material comprising a hydrogel, for the delivery of an active agent. The hydrogel comprises one or more isolated peptides and an active agent encapsulated in the hydrogel. The hydrogel is at least partially in a ?-sheet conformation. Further provided are a method for the encapsulation of an active agent in a hydrogel, a method for treating or diagnosing a condition or disease in a subject in need thereof.

Abstract: The present disclosure refers to a method of obtaining metal ions from a battery, the method comprising adding a crushed battery to a leaching solution comprising fruit and an ammonium salt, thereby obtaining a leachate comprising metal ions.

Abstract: Disclosed herein is a composite scaffold material that includes a crosslinked polymer matrix formed from a non-mammalian collagen and a crosslinking agent and/or a crosslinked polymer matrix formed from a non-mammalian collagen that has undergone self-crosslinking, and a plurality of calcium phosphate particles distributed within the crosslinked polymer matrix, where the composite scaffold material is porous. Also disclosed herein are methods of manufacturing the composite scaffold material and uses thereof. Further disclosed herein is a method of obtaining collagen from a non-mammalian source.

Abstract: The present invention provides an amino acid-functionalized nanoparticle, comprising: a nanoparticle having a dimension in the range of units of nanometers to 100 nanometers, and having an external surface; and a plurality of amino acid molecules conjugated to the external surface of the nanoparticle, the amino acid molecules having a chemical property that can induce a cancer cell to ingest the functionalized nanoparticle; a method of producing such a nanoparticle; and uses of the nanoparticle.

Abstract: The present disclosure refers to a method of obtaining metal ions from a battery, the method comprising adding a crushed battery to a leaching solution comprising fruit and organic acid, thereby obtaining a leachate comprising metal ions, wherein the method is performed at a temperature above 80° C.
