Qaphela: ngokwezidingo zomsebenzisi ze-nano particle ingahlinzeka ngemikhiqizo yosayizi ehlukene.

Ukusebenza komkhiqizo nokusetshenziswa:

I-graphene ingenye yezinto ezintsha ezithakazelisa kakhulu.Isakhiwo sawo sakhiwe ngama-sublattice amabili alinganayo futhi anesidleke.I-doping yama-athomu ahlukahlukene iyindlela ebalulekile yokuphula ukwakheka kwe-symmetry futhi iguqule izici zayo ezibonakalayo.

Ama-athomu e-nitrogen anobukhulu obufanayo nama-athomu ekhabhoni futhi kulula uma kuqhathaniswa ukuthi afakwe kwi-lattice ye-graphene.Ngakho-ke, i-nitrogen doping idlala indima ebalulekile ocwaningweni lwezinto ze-graphene.Ku-graphene ye-monolayer, i-doping esikhundleni ingasetshenziswa ukuguqula izakhiwo zayo ze-elekthronikhi ngesikhathi sokukhula.

I-nitrogen doping ye-graphene ingavula igebe lebhande futhi ilungise uhlobo lokuqhuba, iguqule isakhiwo se-electronic, futhi ithuthukise ukuminyana kwabathwali bamahhala, ukuze kuthuthukiswe ukuqhutshwa nokuzinza kwe-graphene.Ngaphezu kwalokho, ukwethulwa kwesakhiwo se-athomu esine-nitrogen kugridi yekhabhoni yegraphene kungandisa amasayithi asebenzayo akhangisiwe ebusweni be-graphene, ngaleyo ndlela kuthuthukise ukusebenzisana phakathi kwezinhlayiya zensimbi ne-graphene.Ngakho-ke, ukusetshenziswa kwe-graphene ene-nitrogen-doped emishinini yokugcina amandla kunezinto eziphakeme kakhulu ze-electrochemical futhi kulindeleke ukuthi kuthuthukiswe kube into esebenza kahle kakhulu ye-electrode.Ucwaningo olukhona luphinde lwabonisa ukuthi i-graphene ene-nitrogen-doped ingathuthukisa kakhulu izici zomthamo, ukushaja okusheshayo namandla okukhipha kanye nempilo yomjikelezo wezinto zokugcina amandla, futhi inamandla okusebenza amakhulu emkhakheni wokugcinwa kwamandla.

I-graphene ene-nitrogen-doped ingenye yezindlela ezibalulekile zokwenza i-graphene isebenze futhi idlala indima ebalulekile ekwandiseni inkambu yokusetshenziswa kwe-graphene.I-graphene ene-nitrogen-doped ingathuthukisa ngokuphawulekayo izici zamandla, ukushaja okusheshayo kanye nomthamo wokukhipha kanye nokuphila komjikelezo wezinto zokugcina amandla, futhi inamandla amakhulu okusebenza ezinhlelweni zokugcina amandla amakhemikhali njengama-supercapacitors, amabhethri e-lithium ion, amabhethri e-lithium sulfur namabhethri e-lithium angenalutho.

Izimo zokugcina

Lo mkhiqizo kufanele ugcinwe endaweni eyomile, epholile futhi evala imvelo, awukwazi ukuchayeka emoyeni, ngaphezu kwalokho kufanele ugweme ukucindezela okunzima, ngokusho kokuthutha kwezimpahla ezijwayelekile.

Q: Ungakwazi ukungenzela i-quote/invoyisi ye-proforma?IMP: Yebo, ithimba lethu labadayisi lingakunikeza izingcaphuno ezisemthethweni. Nokho, kufanele uqale ucacise ikheli lokukhokha, ikheli lokuthumela, ikheli le-imeyili, inombolo yocingo kanye nendlela yokuthumela.Asikwazi ukudala isisho esinembile ngaphandle kwalolu lwazi.

Umbuzo: Ulithumela kanjani i-oda lami?Ungakwazi yini ukuthumela “impahla yokuqoqa”?A: Singakuthumela i-oda lakho nge-Fedex, TNT, DHL, noma i-EMS ku-akhawunti yakho noma ngokukhokha kusengaphambili.Siphinde sithumele "iqoqo lezimpahla" nge-akhawunti yakho.Uzothola izimpahla Ezinsukwini Ezilandelayo Ezingu-2-5 ngemva kokuthunyelwa, Ezintweni ezingekho esitokweni, ishejuli yokulethwa izohluka ngokusekelwe entweni.Sicela uxhumane nethimba lethu labadayisi ukuze ubuze ukuthi ingabe into ethile ikhona yini esitokweni.

Umbuzo: Uyawamukela ama-oda okuthenga?IMP: Samukela ama-oda okuthenga avela kumakhasimende anomlando wesikweletu kithi, ungasifeksela, noma usithumelele i-oda lokuthenga nge-imeyili.Sicela uqiniseke ukuthi i-oda lokuthenga linakho kokubili isihloko sencwadi yenkampani/isikhungo nesiginesha egunyaziwe kuyo.Futhi, kufanele ucacise umuntu oxhumana naye, ikheli lokuthumela, ikheli le-imeyili, inombolo yocingo, indlela yokuthumela.

Umbuzo: Ngingalikhokhela kanjani i-oda lami?Q: Mayelana nenkokhelo, siyakwamukela ukudluliswa kwezingcingo, inyunyana yasentshonalanga kanye ne-PayPal.I-L/C eyedili elingaphezu kuka-50000USD kuphela. Noma ngesivumelwano sobabili, izinhlangothi zombili zingamukela imigomo yokukhokha.Kungakhathaliseki ukuthi iyiphi indlela yokukhokha oyikhethile, sicela usithumelele ucingo lwasebhange ngefeksi noma i-imeyili ngemva kokuqeda ukukhokha kwakho.

Umbuzo: Ingabe zikhona ezinye izindleko?A: Ngaphandle kwezindleko zomkhiqizo nezindleko zokuthumela, asikhokhisi noma yiziphi izimali.

Umbuzo: Ungakwazi ukungenzela umkhiqizo ngokwezifiso?A: Yebo.Uma kukhona i-nanoparticle esingenayo esitokweni, ngakho-ke yebo, ngokuvamile kungenzeka ukuthi sikukhiqizele yona.Kodwa-ke, imvamisa idinga inani elincane lenani eli-odwe, futhi cishe amaviki angu-1-2 wokuhola.

Q. Okunye.IMP: Ngokwawo wonke ama-oda athile, sizoxoxa nekhasimende mayelana nendlela yokukhokha efanelekile, sibambisane ukuze siqedele kangcono ezokuthutha kanye nemisebenzi ehlobene.

Ungasithinta kanjani?
