Ungaqinisekisa Kanjani Ukuqinisekiswa Kokuqukethwe Kwe-Scandium (Sc) Kwe-Turbine Blades?
Ukwakheka kwezinto eziyisisekelo kunquma ngqo amandla omshini we-turbine blade, ukumelana ne-oxidation, kanye nokukhuthazela kokushisa. Ama-Superalloy athembele ezilinganisweni eziqondile ze-nickel, i-chromium, ne-cobalt ukuze kube nokuqina kwesakhiwo ngaphansi kuka-1,000°C. Ukuphambuka okuncane njenge-±0.1% ekuhlanganiseni ...Funda kabanzi -
Kungani i-Handheld EDXRF iyisihluthulelo sokuhlolwa kwe-Scandium okunembile ezingxenyeni ezingenayo?
Ukuhlolwa kwezingxenye ezingenayo kukhomba amaphutha futhi kuvimbele ukulungiswa kabusha okubizayo ngokuqinisekisa izakhiwo ze-aluminium scandium alloy ngaphambi kokuba izingxenye zifinyelele ekukhiqizweni. Ukwakheka kwe-alloy okungalungile kuthinta ngqo ukusebenza komkhiqizo, kwandisa amazinga amaphutha, futhi kuholela ekuwohlokeni...Funda kabanzi -
Ingabe i-X-Ray Fluorescence Spectroscopy Ingakwazi Ukulinganisa Ngokunembile I-Calcium ne-Phosphorus Ekudleni Kwezinkukhu?
I-calcium ne-phosphorus zakha ngaphezu kuka-70% wokuqukethwe okuphelele kwamaminerali emasakeni ezinkukhu, okwakha i-hydroxyapatite matrix ebangela ukuqina kwamathambo namandla. I-calcium efanele ekudleni kwezinkukhu izuzisa ukukhula kwamathambo, ivimbele izifo ezifana nama-rickets kanye nama-os...Funda kabanzi -
Ukuhlolwa Kwe-Calcium Ezitshalweni Eziyisisekelo Ukuze Kuzalwe I-Biofortification?
Ukuntuleka kwe-calcium ekudleni emhlabeni wonke kuthinta abantu abangu-30%. Emazweni anengeniso ephansi nephakathi nendawo, izitshalo eziyisisekelo azinayo i-calcium ngemva kokucutshungulwa, okwenza lesi sikhala sibe sibi kakhulu. Imiphumela emibi ihlanganisa i-osteoporosis, ukukhula okuphazamisekile ezinganeni, ukwakheka kwamathambo okubuthakathaka, kanye nokwanda...Funda kabanzi -
Ukuphambuka kwe-Acetonitrile Kuthinta Kanjani Isivuno se-Neonicotinoid?
Ukulinganisa ubuningi obuqondile obuqondile kubalulekile ekukhiqizweni kwe-acetonitrile (methyl cyanide). Ukuguquguquka okuphezulu kwe-Acetonitrile kanye nokuxubana okuphelele nokuhlukaniswa kwamanzi okunzima, okudinga idatha eqhubekayo yokubuyisa i-solvent enembile kanye nokwenza ngcono isivuno. Okuqondile ...Funda kabanzi
