  • Ubuchwepheshe obuyisisekelo bokufakwa komphunga wamakhemikhali othuthukisiwe nge-plasma (i-PECVD)

    1. Izinqubo eziyinhloko zokufakwa komoya wamakhemikhali othuthukisiwe nge-plasma Ukufakwa komoya wamakhemikhali othuthukisiwe nge-plasma (i-PECVD) ubuchwepheshe obusha bokukhula kwamafilimu amancane ngokusabela kwamakhemikhali kwezinto zegesi ngosizo lwe-plasma ekhipha ukukhanya. Ngoba ubuchwepheshe be-PECVD bulungiswa ngegesi...

  • Iyini isimiso semoto yamaseli kaphethiloli e-hydrogen?

    I-fuel cell uhlobo lwedivayisi yokukhiqiza ugesi, eguqula amandla amakhemikhali kuphethiloli abe amandla kagesi ngokusabela kwe-redox kwe-oxygen noma amanye ama-oxidants. Uphethiloli ovame kakhulu yi-hydrogen, okungaqondwa njengokusabela okuphambene kwe-electrolysis yamanzi ku-hydrogen kanye ne-oxygen. Ngokungafani ne-rocket...

  • Kungani amandla e-hydrogen edonsela ukunaka?

    Eminyakeni yamuva nje, amazwe emhlabeni jikelele akhuthaza intuthuko yemboni yamandla e-hydrogen ngesivinini esingakaze sibonwe. Ngokusho kombiko okhishwe ngokubambisana yi-Hydrogen Energy Commission yamazwe ngamazwe kanye ne-McKinsey, amazwe nezifunda ezingaphezu kuka-30 akhiphe imephu yendlela ...

  • Izakhiwo kanye nokusetshenziswa kwe-graphite

    Incazelo Yomkhiqizo: i-graphite Impuphu ye-graphite ithambile, imnyama grey, inamafutha futhi ingangcolisa iphepha. Ubulukhuni bungu-1-2, futhi buyanda bube ngu-3-5 ngokwanda kokungcola ohlangothini oluqondile. Amandla adonsela phansi athile angu-1.9-2.3. Ngaphansi kwesimo sokuhlukaniswa komoya-mpilo, iphuzu layo lokuncibilika li...

  • Intengo ye-graphite electrode inyuka muva nje

    Ukwenyuka kwentengo yezinto zokusetshenziswa kuyimbangela eyinhloko yokwenyuka kwamanani kwakamuva kwemikhiqizo ye-graphite electrode. Isizinda senhloso kazwelonke "yokungakhiqizi i-carbon" kanye nenqubomgomo eqinile yokuvikela imvelo, inkampani ilindele intengo yezinto zokusetshenziswa ezifana ne-petroleum...
