CONTROLLED RELEASE FERTILIZER ENCAPSULATED BY GLUTARALDEHYDE-CROSSLINKED CHITOSAN USING FREEZE-DRYING METHOD

A new encapsulation of NPK fertilizer hydrogel granules made from glutaraldehyde crosslinked read more chitosan has been successfully fabricated.This designed fertilizer was aimed to maximize the fertilizing process in the soil, as the environmental pollution affected by the excess release of the nutrients can be prevented.The granule was prepared

Due to the small thermal neutron absorption cross section of 11B isotope, high abundance 11BF3 is regarded as an important ion implanted gas and P-type doping source, and is mainly used in semiconductor material manufacturing process to significantly improve the anti-radiation interference ability of semiconductor devices.In order to achieve the op
