Kedu ihe bụ cerium oxide? Kedu ihe eji eme ya?

Cerium oxide, makwaara dị kacerium dioxide, nwere usoro ihe omimiCeO2. Enwere ike iji ya dị ka ihe na-egbuke egbuke, ihe na-akpali akpali, ndị na-ekpo ọkụ UV, cell electrolytes mmanụ ụgbọala, ndị na-ekpochapụ ụgbọala, seramiki eletrọnịkị, wdg.

Ngwa kacha ọhụrụ na 2022: Ndị injinia MIT na-eji ceramik mee ka mkpụrụ ndụ mmanụ glucose na-eme ka ngwaọrụ etinyere n'ime ahụ. A na-eji cerium dioxide mee electrolyte nke mkpụrụ ndụ mmanụ glucose a, nke nwere nnukwu ion conductivity na ike igwe ma na-ejikarị ya eme ihe dị ka electrolyte maka mkpụrụ ndụ mmanụ hydrogen. A gosikwara na Cerium dioxide na-ejikọta ya

 

Na mgbakwunye, obodo na-eme nchọpụta ọrịa cancer na-arụsi ọrụ ike na-amụ cerium dioxide, nke yiri zirconia nke a na-eji na-etinye n'ime eze ma nwee biocompatibility na nchekwa.

A na-eji ya maka ngwaahịa absorption UV

 

N'ihe ịchọ mma dị elu, a na-eji ihe mejupụtara nano CeO2 na SiO2 kpuchie elu dị ka ihe ndị na-amịpụta UV bụ isi iji merie ihe ndọghachi azụ nke TiO2 ma ọ bụ ZnO nwere agba cha cha na ọnụego nnabata UV dị ala.

 

Na mgbakwunye na iji ihe ịchọ mma, nano CeO2 nwekwara ike ịgbakwunye na polymers iji dozie eriri ịka nká nke UV, na-ebute akwa eriri kemịkalụ nwere oke mkpuchi ọkụ UV na thermal radieshon. Arụmọrụ a dị elu karịa TiO2, ZnO, na SiO2 a na-eji ugbu a. Tụkwasị na nke ahụ, nano CeO2 nwekwara ike ịgbakwunye na mkpuchi iji guzogide radieshon ultraviolet ma belata ịka nká na mmebi nke polymers.
