Ungaqinisekisa njani ukuqinisekiswa komxholo weScandium (Sc) weeTurbine Blades?
Ukwakheka kwezinto ezisisiseko kumisela ngokuthe ngqo amandla oomatshini e-turbine blade, ukumelana ne-oxidation, kunye nokunyamezela kobushushu. Ii-Superalloys zixhomekeke kwiiratio ezichanekileyo ze-nickel, i-chromium, kunye ne-cobalt ukuze kubekho ukuqina kwesakhiwo phantsi kwe-1,000°C. Ukuphambuka okuncinci njenge-±0.1% ekudibaniseni ...Funda ngokugqithisileyo -
Kutheni i-Handheld EDXRF ingundoqo yovavanyo oluchanekileyo lweScandium kwiindawo ezingenayo?
Ukuhlolwa kweenxalenye ezingenayo kuchonga iziphene kwaye kuthintele ukuphinda kusetyenziswe imali eninzi ngokuqinisekisa iipropati ze-aluminium scandium alloy ngaphambi kokuba iinxalenye zifikelele kwimveliso. Ukwakheka kwe-alloy engalunganga kuchaphazela ngokuthe ngqo ukusebenza kwemveliso, kunyusa amazinga eziphene, kwaye kukhokelela ekuwohlokeni...Funda ngokugqithisileyo -
Ngaba i-X-Ray Fluorescence Spectroscopy inokulinganisa ngokuchanileyo iCalcium kunye nePhosphorus kwiZidlo zeenkukhu?
I-calcium kunye ne-phosphorus zenza ngaphezulu kwe-70% yomxholo weeminerali ezikwii-skeletons zeenkukhu, zenza i-hydroxyapatite matrix enoxanduva lokuqina kwamathambo kunye namandla. I-calcium efanelekileyo ekutyeni kweenkukhu inceda uphuhliso lwamathambo, ithintele iingxaki ezifana ne-rickets kunye ne-os...Funda ngokugqithisileyo -
Ukuhlolwa kweCalcium kwiZityalo eziBanzi ukuze kufuywe iBiofortification?
Ukunqongophala kwe-calcium ekutyeni kwihlabathi liphela kuchaphazela ama-30% abemi. Kumazwe anengeniso ephantsi nephakathi, izityalo ezisisiseko azinayo i-calcium emva kokulungiswa, nto leyo eyenza lo msantsa ube mandundu. Iziphumo ezibi ziquka i-osteoporosis, ukukhula okungahambi kakuhle ebantwaneni, ukwakheka kwamathambo okubuthathaka, kunye nokwanda...Funda ngokugqithisileyo -
I-Acetonitrile Deviation Inefuthe Elinjani Kwimveliso Ye-Neonicotinoid?
Ukulinganiswa koxinano oluchanekileyo olukwimigca kubalulekile kwimveliso ye-acetonitrile (methyl cyanide). Ukuguquguquka okuphezulu kwe-Acetonitrile kunye nokungavisisani ngokupheleleyo nokwahlukana kwamanzi, okufuna idatha eqhubekayo yokubuyisela i-solvent ngokuchanekileyo kunye nokwenza ngcono isivuno. I-Inline ...Funda ngokugqithisileyo
