A pod for removing odor and moisture from a substantially confined area has deodorant and moisture adsorbing properties to counteract unpleasant odours, especially odours due to microbial growth. The pod is removably insertable into footwear, gloves, skates, lockers, sports gear, workout gear or any gear or enclosure. The pod has a fabric pouch with anti-microbial properties and contains fragrance-releasing particles and desiccant granules. The moisture adsorbing properties of the pod may be thermally rechargeable. The pods may be attached to other pods in use.

Methods and compositions for the adsorptive removal of methyl tertiary butyl ether (MTBE) from contaminated water sources and systems. The compositions contain carbon fly ash doped with silver nanoparticles at specific mass ratios. Methods of preparing and characterizing the adsorbents are also provided.

Described herein are methods and compositions for preparing an adsorbent composition for sustained silver ion release is provided. The method comprises impregnating silver nanoparticles on an organic-templated-nanometal oxyhydroxide. Particle size of the silver nanoparticles is less than about 50 nm. The adsorbent composition is antimicrobial in water. In an aspect, the organic-templated-nanometal oxyhydroxide is organic-templated-boehmite nanoarchitecture (OTBN). The resultant adsorbent composition is used as a water filter in a water purification device.

A composite particle having a fluorinated surface and a discontinuous layer of gold nanoparticles disposed on the fluorinated surface, articles that include such particles, and methods of using the particles and the articles for removal of ethylene.

A Biorefinery System (BIOSYS) that effectively treats all human activity-derived waste (black water, grey water, and food waste streams) using biological systems and that produces as process by-products: recovered potable water, liberated free oxygen, edible protein cake (with and without lipids), soil amendments, and machinery lube oils. Additionally, the system captures and chemically binds carbon dioxide into microbial cells and associated by-products, thus producing recovered usable returned cabin air.

The present invention provides composite material having a porous graphene-based foam matrix and comprising porous inorganic micro-particles and metal oxide nano-particles distributed throughout the foam matrix.

Apparatus and methods which can remove, for example, mercury (Hg) from industrial flue gases. An exemplary sorbent polymer composite (SPC) can include a polymer, a sorbent which has a microstructure, and a transition metal halide in the microstructure. The transition metal halide can include silver (Ag), iodine (I), or both (AgI). A method for producing the SPC can include applying a non-halide salt of a transition metal to a sorbent, applying a non-transition metal halide to the sorbent, so as to react the non-transition metal halide with the non-halide salt of the transition metal, thereby forming a transition metal halide within the microstructure of the sorbent.

Porous nanocomposite fibers are fabricated by electrospinning a solution including a polymer, a solvent, and a nanomaterial. The resulting fibers can be used in the form of a filter to remove a variety of organic and inorganic contaminants from an aqueous environment, and provide a macroscopic matrix to facilitate separation of the nanomaterial from the aqueous environment.
