  • Publication number: 20220072521
    Abstract: Modified crystalline zeolite materials have a zeolite framework with both tetra-coordinate Lewis aluminum single sites and Brønsted aluminum sites. The tetra-coordinate Lewis aluminum single sites include aluminum atoms covalently bonded to a variable group and to two oxygen atoms and further coordinated to a third oxygen atom. The variable group may be alkyl, hydride, or hydroxyl. Methods for incorporating tetra-coordinate Lewis aluminum single sites into a crystalline zeolite material include contacting the crystalline zeolite material with a dialkylaluminum hydride R2AlH, where each R is alkyl, to react the dialkylaluminum hydride with the zeolite framework and form tetra-coordinate alkyl aluminum single sites. Heating the alkyl-aluminum zeolite induces ?-hydride elimination of the alkyl groups, whereby tetra-coordinate aluminum hydride single sites are formed.

  • Publication number: 20220071216
    Abstract: The disinfectant-dosing microgel is formed from a mixture of a sol and a solution of a disinfecting and deodorizing agent. In use, the sol phase is transformed, by various conditions, into an active microgel. The disinfectant-dosing microgel is applied to the waste, such as by spraying, mixture therewith or the like. The combination of the sol and the solution of the disinfecting and deodorizing agent or, alternatively, the combination of the polymer and the solution of the disinfecting and deodorizing agent, is triggered to transform from the sol phase into the active microgel for long-term disinfection and deodorization of the waste by the temperature, pH, and/or salt concentration of the waste. The transformation to the active microgel for long-term disinfection and deodorization of the waste can also be initiated by adding chemical substances to alter the pH or promote gelation, either before, during or after application to the waste.

  • Patent number: 11269203
    Abstract: Polarization-independent focusing is advantageously achieved by a multifocal system having a polarization beam splitter (PBS) to split an unpolarized light beam into two orthogonally linearly-polarized (LP) light beams. The two LP light beams are reflected by mirrors to travel in opposite directions and enter into a variable-focusing module at two ends thereof, respectively. The module includes waveplates to convert the LP light beams into two circularly-polarized (CP) light beams at both ends of an optical assembly. The optical assembly is formed with a stack of birefringent optical elements including at least one geometric phase lens and one polarization selector that may be electrically modulated to select the optical power in focusing the two CP light beams. Followed by the waveplates converting two focused CP light beams to two focused LP light beams and upon mirror reflection, the beams are finally recombined by the PBS to form one focused light beam.

  • Patent number: 11267744
    Abstract: A gold mine cyanide tailing disposal method is provided. The disposal method performs a harmless decyanation treatment on a cyanide tailing slurry obtained from a mineral processing plant, and then performs a resource treatment where a cyanide tailing slurry is subjected to a thickening to obtain a higher concentration. When a backfill is needed, a paste is produced by adding a cementing material after a homogenized stirring of a two-stage horizontal agitator pumped to an underground mining site for filling by a plunger pump. The cementing material is to solidify an underflow and prevent cyanide from being filtered out. When a backfill is not needed, the paste is directly delivered to an open storage area for storing by the plunger pump.
