Ebhizinisini lethu likawoyela negesi, ukukhiqizwa kwehle ngo-8% unyaka nonyaka engxenyeni yokuqala. Izizathu zibandakanya ukwehla kwemvelo kanye nokulungiswa okusebenzayo nokusebenza, okwenziwayo ukuze kuthuthukiswe ukwethembeka kwempahla ukuze kukhuphuke indawo ekahle ezindaweni ezilandelayo. Ngokwenza lokhu manje, siqinisekisa ukuthi sinengxenye yesibili eqinile kulo nyaka lapho amanye alawo maphrojekthi eza ngokusakaza.

Ucwaningo luye lwabonisa futhi ukuthi udoti wesikhumba ungcolisa umhlabathi ongaphezulu waseHazaribagh. Ucwaningo lwango-1999 lwathola ukungcoliswa yizinsimbi ezihlukahlukene, kuhlanganise nomthofu ne-cadmium. Iphethe ngokuthi:

Isakhiwo nokwakheka kwesixhumi esibonakalayo esakhiwe ku-Al electrode ku-AlCl3-IL electrolyte (i-Tal electrode) kuphenywe kusetshenziswa i-attenuated total reflection-Fourer transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), energy-dispersive x -ray spectroscopy (EDX), kanye ne-x-ray photoelectron spectroscopy (XPS). Uma kuqhathaniswa ne-Al ehlanzekile, ingaphezulu le-Tal licebile ngamaqembu asebenzayo we-organic (Fig. 1A). Ngaphezu kokuba khona kwamaqembu e-C=N kanye ne-C–H nawo ayinsada ku-electrolyte ye-IL ehlanzekile, isithuthukisi esikhulu eqenjini elisebenzayo le-C=C nokuvela kwezinhlobo eziqukethe iqembu le-C=O kutholwa ku-Tal. Lokhu kubuka kuhambisana nokuvela kwefilimu ezinzile endaweni ye-TAl. Ukwengeza, izindlela zokudlidliza ze-infrared ezihlotshaniswa nendandatho ye-imidazolium (1100 kuya ku-600 cm−1) ku-IL (21) anyamalala kakhulu lapho ukwelashwa, okubonisa ukuthi i-IL electrolyte iguqulwa ngamakhemikhali ku-Al interface (Fig. 1A). Ukuhlaziywa kwe-XPS kwe-Pristine Al ne-TAl kunikeza imininingwane eyengeziwe ezicini zamakhemikhali ezingaphezulu ze-TAl. Imiphumela ku-Fig. 1B, isibonelo, ibonisa ukuthi ngisho nangemva kokupholishwa, i-Al2O3 isabusa ikhemistri engaphezulu ye-Al. Ngokuphambene, i-spectra ye-Al2p XPS ye-TAl substrate iveza ukuthi inhlanganisela enamandla amakhulu abophezelayo, okungabalelwa kusawoti we-Al, okungenzeka ukuthi i-AlCl3, iyabusa. Lokhu kuqinisekiswa i-spectra ye-Cl2p XPS, ngoba amandla okubopha e-Cl2p atholakala cishe ku-199 eV ahambisana ne-valence engu- -1 (Fig. 1C). I-spectra ye-N1s XPS iphinde ibonise ukuthi ukuxhumana kwe-TAl kunothile ngezinhlobo eziqukethe i-nitrogen. Ukuphakama okubukhali ku-401 eV kungasetshenziswa ukukhomba ngokungananazi ubukhona be-ion imidazole (Fig. 1D). Uma kuqhathaniswa nendawo ecwebile ye-Al epholishiwe (Fig. 1E), isimo sendawo ye-TAl ngokusobala sishelela (Fig. 1F). Kusuka ekubukeni kwesigaba esiphambanayo okufanekiselwa yi-SEM, ungqimba oluphakathi kobuso lubonwa ku-Al substrate. Ukuhlaziywa kwe-EDX kwesendlalelo kukhombisa ukuthi kucebile ku-elementi Al, Cl, no-N (Fig. 1G kanye ne-fig. S1).

Ibhayisikili letshe elisha sha i-WI.DE (Winding Detours) elivela ku-Open lithatha amathayi abanzi kune-UP yasekuqaleni yenkampani kusukela ngo-2015 futhi lingcono kakhulu kulo, elinesivinini esiphezulu kuzo zonke izinhlobo zezindawo, elifakwe ukuphatha okuhle kanye nesisindo esincane esivela okwangempela kusekelwe kuyo. Kodwa ithegi yentengo iyibeka ngaphandle kwemingcele kwabaningi futhi ungayithenga kuphela njenge-frameset enokukhethwa kombala owodwa.

I-Vosko, SH, Wilk, L. & Nusair, M. Amandla anembile e-electron liquid ancike ku-spin ezibalo zendawo zokuphonswa kwe-spin - ukuhlaziya okubucayi. Angakwazi. J. Phys. 58, 1200–1211 (1980).

Amanye amaphuzu we-hacker ejwayelekile igesi esetshenzisiwe. Kulokhu i-aluminiyamu (i-aluminiyamu) ama-brazing rods ayizinga lokushisa eliphansi elanele lokusebenzisa amasilinda egesi alahlwayo ashibhile futhi i-MAP Pro (ukushintsha kwe-MAPP) cishe ingcono kancane kune-Propane inqobo nje uma isika sokushisa i-brazing yakho ingenkulu kakhulu.

Kunabasebenzi abangaba ngu-8,000 kuya ku-12,000 abashuki besikhumba, abakhuphukela cishe ku-15,000 izinyanga ezimbili noma ezintathu kulandela umkhosi we-Eid-al-Adha, inkathi ephakeme yokucubungula izikhumba ezingavuthiwe.[3]

I-GMAW ku-aluminium ivame kakhulu ezindaweni zokukhiqiza okuphezulu…I-GTAW ijwayeleke kakhulu ekusetshenzisweni okungokwezifiso.

Ukhuni oluyisicaba, imichilo yokhuni, noma ngabe ukubiza ngani, le nto yokuklama ilapha ukuze ihlale ngaphakathi eSingapore.

Isifanekiso S9. Izici ze-Electrochemical zamabhethri e-Al-MnO2 asebenzisa i-Tal anode–, Al(CF3SO3)3-, kanye ne-Al2(SO4)3-based aqueous electrolyte.

Leso sikali singafinyelela ku-300kg/600lbs. Bengingalindele ukuthi ukuxhumeka kuqine kangako ngakho-ke ukusethwa kwami ​​​​kwakungalungiswanga ngokusobala. Ngingathanda ukwakha isethi yokulenga yokuhlola izinto ezinjengalezi esikhathini esizayo. Ngicabanga ukuthi ulahlekelwa iphuzu levidiyo yami. Abantu abaningi abadingi uxhumano oluqine ngokwanele ukuze badonse amashubhu e-CF ku-2. Ngisanda kuklama indlela elula yokwenza amaphethelo enduku enziwe ngokwezifiso aqine kakhulu kumaphrojekthi/amarobhothi wokuzilibazisa.

Uma ufuna umgibeli osezingeni eliphezulu futhi wenze izinto ezingajwayelekile, kodwa ungafuni ukuchitha imali eshisiwe, i-Metrix iyinketho ehloniphekile.
