A thermoelectric module comprising nanostructured SnO and SnO, and electrodes arranged between two electrical insulating substrates is described. The nanostructured SnO may be in the form of nanosheets and acting as p-type pillars of the module. The nanostructured SnOmay be in the form of nanospheres and acting as n-type pillars of the module. This thermoelectric module is evaluated on the voltage, current, and power of the electricity generated once subjected to a temperature gradient.

A method of removing an organic pollutant from water by contacting the water with a ball milled and sonicated oil fly ash powder to adsorb the organic pollutant onto the ball milled and sonicated oil fly ash powder. A method of producing a ball milled and sonicated oil fly ash powder involving ball milling oil fly ash to provide ball milled oil fly ash particles with an average particle size of less than 1 &#x3bc;m and sonicating the ball milled oil fly ash particles in an aqueous medium to form the ball milled and sonicated oil fly ash powder. A method of improving recovery of valuable metals/elements from oil fly ash.

Coaxial electrospinning is used to encapsulate a chitin-lignin based hybrid gel with polycaprolactone (PCL). Antibiotics and/or other bioactive agents loaded into the core and/or shell layer of the fibrous platform are released in a controlled and sustained manner that effectively inhibits both Gram-positive and Gram-negative bacteria without cytotoxicity to mammalian cells. The PCL shell layer provides longer life for the CL gels in a wet environment and allows sustainable drug release. The PCL-coated CL nanofiber scaffolds can be loaded with antimicrobial nanoparticles, antibiotics, oxygen-releasing agents, antioxidants and/or growth factors that promote healing when used as a controlled drug release dressing for chronic wounds, such as diabetic ulcers.

A cryogel which includes lignin nanoparticles embedded in crosslinked gelatin. The cryogel is formed at subfreezing temperatures where aggregation of polymerized or crosslinked materials is prevented by ice crystals. When thawed, the cryogel is a densely crosslinked microporous composition with a plurality of pores ranging from 50-150 &#x3bc;m in size. The cryogel combines a natural bio waste polymer in the form of lignin together with a collagen derived natural polymer. Incorporation of lignin within gelatin improves the mechanical performance of the cryogel and enhances its shape recovery rate. The macropororous composition inhibits growth of both gram positive and gram negative bacteria. In addition, the macoporous composition exhibits excellent free radical scavenging activity. All of the properties make the cryogel an excellent material for wound healing and tissue engineering applications.
