Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

Destruction of PFAS via an oxidation process and apparatus suitable for transportation to contaminated sites

An apparatus for extracting a material from a liquid includes a concentration stage having a filter, a first path from the filter, and a second path from the filter. Under this configuration, the concentration stage accepts an initial liquid volume. A first liquid not having material collected by the filter is passed along the first path, and concentrated liquid having material therein, which is entrapped by the filter, is directed to the second path. The apparatus also includes an aerosolizing stage coupled to the concentration stage that converts the concentrated liquid into an aerosol and a drying stage that dries the aerosol such that material extracted from the aerosol onto a material substrate.

Extraction of materials from liquids

An apparatus for extracting a material from a liquid includes a concentration stage having a tangential flow filter, a first path from the tangential flow filter, and a second path from the tangential flow filter. Under this configuration, the concentration stage accepts an initial liquid volume. A first liquid not having material collected by the tangential flow filter is passed along the first path, and concentrated liquid having material therein, which is entrapped by the filter, is directed to the second path. The apparatus also includes an aerosolizing stage coupled to the concentration stage that converts the concentrated liquid into an aerosol and a drying stage that dries the aerosol such that material extracted from the aerosol onto a material substrate.

Various implementations of the invention provide for a one-piece surgical stapling apparatus that includes a stapler head and an anvil head assembly. The anvil head assembly is tiltable between a tilted position and a transverse position, and anvil plates of the anvil head assembly are moveable about one or more hinges between a closed and an open position. When in the tilted and closed positions, the anvil assembly has a reduced footprint that allows the anvil assembly to be passed directly through a trocar and holes created in the bodily tissues, which eliminates the need for separate placement of the anvil head. At the site of the anastomosis, the anvil head assembly can be moved to the transverse and open positions, and the stapling head may be engaged to fire staples against the anvil head.
