Latest Patents

One of his latest patents is a "Selenium-doped nano silica sol used for producing selenium-enriched rice and capable of suppressing absorption and accumulation of heavy metals in paddy rice." This invention discloses a selenium-doped nano-silica sol that inhibits the absorption of heavy metals in rice while promoting the growth of selenium-rich rice. The preparation method involves using nano-silica sol as a carrier, sodium selenite as a raw material, and vitamin C as a reducing agent. The resulting sol is stable, transparent, and has a silica content of over 20% and a selenium content of over 1%. It is safe for application and has no toxic side effects on crops.

Another significant patent is the "Composite foliage Si fertilizer for lowering contents of heavy metals and nitrate in vegetables, and preparation method thereof." This invention relates to a molybdenum-silica compound sol designed to reduce heavy metals and nitrates in vegetables. The fertilizer comprises 10-25 wt% silica and 0.05-5.5 wt% molybdenum ions. The combination of silica with molybdenum effectively prevents the absorption of nitrates in vegetables, and the addition of rare earth elements enhances this ability. The preparation method is simple and can be executed under mild conditions, allowing for large-scale production.
