I-Sulfo-NHS: Isayensi ngemuva kwendima yayo ebalulekile ocwaningweni lwe-biomedical
Ingabe usebenza emkhakheni wocwaningo lwe-biomedical? Uma kunjalo, kungenzeka ukuthi uzwile nge-Sulfo-NHS. Njengoba indima ebalulekile yale nhlanganisela ocwaningweni iqhubeka nokuqashelwa, le nhlanganisela ingena ezindaweni zokucwaninga eziningi emhlabeni jikelele. Kulesi sihloko, sixoxa ngokuthi iyini i-Sulfo-NHS nokuthi kungani ...Funda kabanzi -
I-Isoamyl Nitrite vs. Amyl Nitrite: Odinga Ukukwazi
I-isoamyl nitrite kanye ne-amyl nitrite amagama amabili avame ukuzwakala emhlabeni wezidakamizwa nezokungcebeleka. Kodwa ingabe ziyafana? Lona umbuzo ojwayelekile abantu abawubuzayo, futhi silapha ukuze sikuchazele wona. Okokuqala, ake sichaze ukuthi iyini i-isoamyl nitrite ne-amyl nitrite. Kokubili kungaphansi...Funda kabanzi -
Isayensi ngemuva kwe-nitrate yesiliva kanye nokusetshenziswa kwayo okubanzi
I-Silver nitrate iyinhlanganisela eguquguqukayo ebisetshenziswa ezimbonini ezahlukahlukene amakhulu eminyaka. Kuyinhlanganisela eyakhiwe ngama-athomu esiliva, i-nitrogen ne-oxygen. I-Silver nitrate inezinhlelo zokusebenza ezihlukahlukene, kusukela ekuthwebuleni izithombe zendabuko kuye kwezokwelapha nokunye. Ngakho-ke, yini i-nitrate yesiliva enhle ...Funda kabanzi -
Isingeniso kanye Nokusetshenziswa Kwe-Silver Nitrate
I-nitrate esiliva iyinhlanganisela yamakhemikhali enefomula ethi AgNO3. Iwusawoti wesiliva, futhi isetshenziswa kakhulu ezimbonini ezihlukahlukene ezifana nezithombe, imithi, kanye nekhemistri. Ukusetshenziswa kwayo okuyinhloko kufana ne-reagent ekuphenduleni kwamakhemikhali, njengoba ikwazi ukusabela kalula nge-halides, i-cyanides, nezinye izinhlanganisela. Ku...Funda kabanzi -
Iyini ukusetshenziswa kwe-graphene? Amacala amabili ohlelo lokusebenza akuvumela ukuthi uqonde ithemba lesicelo se-graphene
Ngo-2010, uGeim noNovoselov bawina uMklomelo KaNobel ku-physics ngomsebenzi wabo we-graphene. Lo mklomelo ushiye umxhwele kakhulu kubantu abaningi. Phela, akuwona wonke amathuluzi okuhlola weNobel Prize avamile njenge-adhesive tape, futhi akuyona yonke into yocwaningo enomlingo futhi kulula ukuyiqonda njenge-R...Funda kabanzi -
Ucwaningo mayelana nokumelana nokugqwala kwe-graphene / carbon nanotube eqinisiwe i-alumina ceramic coating
1. Ukulungiswa kokumboza Ukuze kube lula ukuhlolwa kwe-electrochemical yakamuva, i-30mm ikhethwa × 4 mm 304 insimbi engagqwali njengesisekelo.
