Researchers have made a 3D-printable building material by mixing urea and moon dust. It's really gross—but it could really work.
Urea can also be dissolved in water and used as a soil drench or otherwise distributed with irrigation water or applied as a foliar spray. When urea fertilizer is applied to the soil, it combines with water (hydrolysis) to form ammonium carbonate [(NH4)2CO3] through the catalytic action of...
the preferential temperature is 65 to 70 DEG C and the preferential reacting time is 60 to 120 min; and 3) an adsorbent and sulfuric acid solution are added in the solution I, urea-formaldehyde fertilizer slurry is obtained by evenly mixing, and the urea-formaldehyde fertilizer is obtained by...
(Biochemistry) a white water-soluble crystalline compound with a saline taste and often an odour of ammonia, produced by protein metabolism and excreted in urine. A synthetic form is used as a fertilizer, animal feed, and in the manufacture of synthetic resins. Formula: CO(NH2)2. Also called...
1. Melamine resin is manufactured by mixing urea with formaldehyde under heat and pressure. 2. Statistics from the China nitrogenous fertilizer industry association show the country's total output of urea decreased by about 1 million tons this year. ...
Concentrated acids mixed with the same volume of distilled water. The acid is slowly pouredinto the water under constant mixing and cooling. With automati... IO Commission 被引量: 4发表: 1983年 Design and degradation of permanently porous vitamin C and zinc-based metal-organic framework Bioappl...
There has been no disclosure of a storage-stable, clear liquid, partially condensed, urea-formaldehyde fertilizer solution which is sufficiently reactive to allow the urea-formaldehyde condensation to again commence to form slow-releasing and water-insoluble nitrogen when applied to the neutral or acid...
