A non alpha controlled plating bath including Tin species and a trace amount of Polonium species is utilized in a plating tool. The plating tool includes a Polonium filter element to remove Polonium species from the plating bath to selectively plate Tin upon a plating cathode. The filter may include a Titanium inner portion surrounding by a stannic oxide exterior. The filter may reduce the Polonium species by having the polonium absorb and then enter within the stannic oxide matrix. The filter may be located within the plating tool reservoir or filter housing. The filter may be fabricated by forming Tin upon a Titanium backbone and converting the Tin to stannic oxide.

Various embodiments disclosed relate to extraction of target materials using a CZTS sorbent. A method of extracting a target material from a medium includes contacting a copper zinc tin sulfur (CZTS) sorbent with the target material in the medium including the target material to form a used CZTS sorbent that includes the target material. The method also includes separating the used CZTS sorbent from the medium.

A porous sorbent ceramic product includes a three-dimensional structure having an electrically conductive ceramic material, wherein the conductive ceramic material has an open cell structure with a plurality of intra-material pores, a sorbent additive primarily present in the intra-material pores of the conductive ceramic material for adsorption of a gas, and at least two electrodes in electrical communication with the conductive ceramic material.

A method of forming a product for separating gases includes forming a three-dimensional ceramic support, heating the three-dimensional ceramic support at a temperature for an effective duration of time to result in the conductive ceramic material having a plurality of intra-material pores, and incorporating a sorbent additive into the intra-material pores of the conductive ceramic material. Moreover, the three-dimensional ceramic support includes an electrically conductive ceramic material configured for joule heating.

Apparatuses and methods for extracting desired chemical species including, without limitation, lithium, specific lithium species, and/or other chemical compounds from input flows in a modular unit. The input flows may be raw materials in which lithium metal and/or lithium species are dissolved and/or extracted. The apparatuses and methods may include daisy chain flow through separate tanks, a column array, and/or combinations thereof.

A monolithic metal-organic framework (MOF) composite body is disclosed, comprising: MOF crystallites adhered to each other via a binder comprising MOF; and at least 0.15 vol % nanoparticles encapsulated in the MOF body. The nanoparticles have an average particle size corresponding to an average particle diameter in the range 3-200 nm. The nanoparticles may have photocatalytic activity. The MOF composite body is of use for treating water containing an organic dye, the photocatalytic reaction supported by the photocatalytic nanoparticles being a degradation reaction of the organic dye.

A system and method for cleaning, conditioning, and/or rejuvenating carbon-based sorbents is disclosed where a chemical cleaning process is used to separate contaminants from the sorbent. The contaminants can be disposed of or recycled for industrial uses. The cleaned and/or rejuvenated carbon-based sorbent is recycled back into a reverse venturi shaped fluidized bed apparatus for later use. Spent carbon-based sorbent can be routed for appropriate disposal. The carbon-based sorbents include, but are not limited to, activated carbon sorbent and biochar sorbent. Optionally, the sorbents can be processed through the system prior to exposure to contaminated emissions to enhance and increase the porosity of the outer surface of the sorbents.

An emissions control system including a fluidized bed apparatus containing a reactive sorbent material is disclosed for gaseous and non-gaseous contaminated emissions. The reactive sorbent material may be CZTS, CZTS-Alloy, or a carbon-based sorbent material. The fluidized bed apparatus is configured with one or more closed loop sorbent recycling subsystems. The sorbent recycling subsystems include the capability to separate sorbents from each other, separate contaminates from sorbents for disposal and/or recycling, clean and/or rejuvenate sorbents for return to the fluidized bed apparatus, dispose of spent and exhausted sorbents, and replace the spent and exhausted sorbents with new sorbent to maintain consistent sorbent function in the fluidized bed apparatus. Monitoring sensors provide information useful in a method for establishing and maintaining consistent process parameter controls.

A material for moisture removal and/or water harvesting from air may include a hydrophilic material containing micropores and a low water activity material confined within the micropores of the hydrophilic material. Apparatuses containing such materials and methods for moisture removal and/or water harvesting from air by using such materials are also described.
