Impumelelo yesayensi egqwesileyo kwitekhnoloji entsha yokususa i-amonithi esebenza kakuhle, eyenziwe yinkampani entsha yezinto eziseHeilongjiang, eTshayina, yapapashwa ngokusesikweni kwijenali yezemfundo yamazwe ngamazwe iNature ekuqaleni kukaNovemba ka-2025. Iqatshelwa njengenkqubela phambili yehlabathi ekuqulunqweni kwamachiza kunye ne-R&D, le ntsha ifumene ingqalelo enkulu ngenxa yamandla ayo okutshintsha utshintsho lweemolekyuli kumashishini amaninzi anexabiso eliphezulu.
Eyona mpumelelo iphambili ikuphuhliso lwesicwangciso sokususa i-amine ngokuthe ngqo esilawulwa kukwenziwa kwe-N-nitroamine. Le ndlela iphambili ibonelela ngendlela entsha yokuguqulwa ngokuchanekileyo kwee-heterocyclic compounds kunye ne-aniline derivatives—iibhloko ezibalulekileyo zophuhliso lwamayeza kunye nokuhlanganiswa kweekhemikhali ezincinci. Ngokungafaniyo neendlela zemveli zokususa i-amine ezihlala zixhomekeke kwi-intermediates ezingazinzanga okanye kwiimeko ezinzima zokusabela, itekhnoloji elawulwa yi-N-nitroamine inika utshintsho olucacileyo ekusebenzeni kakuhle nasekusebenzisekeni kwezinto ezahlukeneyo.
Iingenelo ezintathu ezibalaseleyo zichaza le ndlela: ukuqheleka kwayo yonke indawo, ukusebenza kakuhle, kunye nokulula kokusebenza. Ibonisa ukusetyenziswa ngokubanzi kwiintlobo ngeentlobo zeemolekyuli ekujoliswe kuzo, isusa imida yeendlela eziqhelekileyo ezithintelwe yisakhiwo se-substrate okanye isikhundla seqela le-amino. Ukusabela kuqhubeka phantsi kweemeko ezithambileyo, kuthintelwa isidingo see-catalysts ezinetyhefu okanye ulawulo lobushushu/uxinzelelo olugqithisileyo, olunciphisa kakhulu umngcipheko wokhuseleko kunye nempembelelo yokusingqongileyo. Okubaluleke kakhulu, ubuchwepheshe buphumelele ukuqinisekiswa kwemveliso yovavanyo lwe-kilogram, bubonisa ukuba bunokwenzeka ukusetyenziswa kwemizi-mveliso emikhulu kwaye bubeka isiseko esiqinileyo sokuthengiswa.
Ixabiso lokusetyenziswa kolu tshintsho ludlulela ngaphaya kwamayeza. Kulindeleke ukuba lusetyenziswe ngokubanzi kubunjineli beekhemikhali, izixhobo eziphambili, kunye nokwenziwa kwezibulala-zinambuzane. Ekuphuhlisweni kwamayeza, kuya kulungelelanisa ukuveliswa kwezinto eziphambili, kukhawulezise inkqubo yophando nophuhliso lwamayeza amancinci eemolekyuli ezifana neearhente zokulwa nomhlaza kunye namayeza e-neurological. Kumacandelo eekhemikhali kunye nezinto, kwenza ukuba ukwenziwa kweekhemikhali ezikhethekileyo kunye nezixhobo ezisebenzayo kube luhlaza kwaye kube nexabiso eliphantsi. Kwimveliso yezibulala-zinambuzane, inika indlela ezinzileyo yokuvelisa izinto eziphezulu zokusebenza ngelixa ithobela imithetho engqongqo yokusingqongileyo.
Olu phuhliso alujongani nje nemingeni ekudala ikho ekuguqulweni kweemolekyuli kodwa lukwaqinisa isikhundla seTshayina ekuveliseni iikhemikhali ezintsha. Njengoko uphuhliso lwemizi-mveliso luqhubeka, ubuchwepheshe bukulungele ukuqhuba inzuzo yokusebenza kakuhle kunye nokunciphisa iindleko kumacandelo amaninzi, nto leyo ebonisa inyathelo elibalulekileyo phambili kutshintsho lwehlabathi oluya kwiindlela zokwenza iimveliso eziluhlaza nezizinzileyo.
