Described here are compositions, methods and apparatus for biological and physical geoengineering. Disclosed are inorganic particles, prill, pucks, or floats for dispersal on a body of water, the compositions having several properties: 1) positive buoyancy, 2) a sustained-release matrix for delivery of iron, calcium, magnesium, zinc, copper, molybdenum, manganese, cobalt, boron, selenium, vanadium, chromium, nickel, sulfur, nitrogen, phosphorus, silicon, preferably as a combination thereof, at biologically efficacious levels, and synergically, 3) a light-reflective surface for increasing planetary albedo when dispersed over large surfaces. These compositions are found to A) increase yields for pelagic aquaculture, B) increase carbon sequestration, and C) provide immediate relief from global warming by directly increasing surface albedo and indirectly by increasing cloud nucleation activity. A preferred composition comprises a mixture of inorganic salts and binders (such as a glass or ceramic) effective for increasing the growth of primary aquatic producers such as coccolithophorids, diatoms, silicoflagellates, dinoflagellates, and microalgae (and higher trophic levels) in a sustained-release composition having a T1 / 2 of 0.5-3 years. To validate resultant carbon fixation and sequestration, a vertical spar buoy is provided. The buoy is designed to resist wave motion while supporting a stable long-term platform and submerged spaceframe with laser particle counters suspended below the 100 year horizon. Validation of exsolation energy credits, issuance of an associated financial instrument, and trading markets for those instruments are also described.

The invention provides a dry chemical reagent strip for detecting calcium, magnesium and zinc of breast milk simultaneously. Specifically, the dry chemical reagent strip is composed of a supporting layer and a detection reagent block. The detection reagent block is whatman filter paper where a detection reagent for detecting calcium, magnesium or zinc is adsorbed, and the detection reagent block is directly pasted to one end of the long-strip-shaped supporting layer. When the dry chemical reagent strip is specifically used, the other end of the supporting layer is held by hand, the detection reagent block is completely soaked in a to-be-detected sample (breast milk) and then taken out, and after a color is stabilized, the color is compared with a standard colorimetric card. The dry chemical reagent strip can detect the content of calcium, magnesium and zinc simultaneously without mutual influence, and the sample is not polluted. The detection process is efficient and simple, and resultdata are reliable.

The invention discloses a preparation method of a cerium-based polishing powder precursor for optical glass and liquid crystal display glass. In the preparation of the precursor, the invention purifies the raw material through physical and chemical methods, that is, firstly, the raw material lanthanum cerium salt is passed through Dissolve and filter to remove dust and other impurity particles in the raw materials; then by controlling the pH value of the precursor preparation between 5.5-7.5, the rare earth lanthanum and cerium are precipitated, while other metal elements such as calcium, magnesium, zinc, iron, Lead and the like do not form precipitates, which can be removed by washing and filtering, and the finally prepared polishing powder can be used for fine polishing of optical glass and liquid crystal display glass. The present invention also adds a composite precipitant composed of phosphate, fluoride, and carbonate during the preparation of the polishing powder precursor, and the particle morphology of the prepared polishing powder precursor is a uniform aggregate with moderate particle size and narrow particle size distribution. , the number of large particles is small. The polishing powder has a high cutting rate and a long service life. After grinding, there is basically no scratch on the glass and the surface finish is good.
