Kwishishini lethu le-oyile kunye negesi, imveliso iphantsi nge-8% ngonyaka kwikota yokuqala. Izizathu zibandakanya ukwehla kwendalo kunye nokugcinwa okukhawulezileyo kunye nokusebenza, okuqhutyelwa ukwandisa ukuthembeka kwe-asethi ukwenzela ukunyusa okugudileyo kwiikota ezilandelayo. Ngokwenza oku ngoku, siqinisekisa ukuba sinesiqingatha sesibini esomeleleyo kulo nyaka xa ezinye zezo projekthi ziza ngokuqhubekayo.

Uphononongo lukwabonise ukuba inkunkuma yesikhumba ingcolisa umhlaba ongaphezulu weHazaribagh. Uphononongo luka-1999 lwafumanisa ukungcoliseka ziintsimbi ezahlukeneyo, kuquka ilothe kunye necadmium. Igqibe kwelokuba:

Ubume kunye nokwakheka kojongano olwenziwa kwi-Al electrode kwi-AlCl3-IL electrolyte (i-Tal electrode) yagocagocwa kusetyenziswa i-attenuated total reflection-Isine siguqule i-infrared spectroscopy (ATR-FTIR), iscanning electron microscopy (SEM), energy-dispersive x -i-ray spectroscopy (EDX), kunye ne-x-ray photoelectron spectroscopy (XPS). Xa kuthelekiswa ne-Al ecocekileyo, umphezulu we-Tal utyetyiswe ngamaqela asebenzayo e-organic (umzobo 1A). Ukongeza kubukho beqela le-C=N kunye ne-C-H ekwaninzi kwi-electrolyte ye-IL ecocekileyo, uphuculo olukhulu kwiqela elisebenzayo le-C=C kunye nokuvela kweentlobo eziqulathe iqela le-C=O zifunyenwe kwi-Tal. Olu qwalaselo luhamba kunye nokubonakala kwefilimu ezinzileyo kwi-TAl surface. Ukongezelela, iindlela ze-infrared vibration ezihambelana nendandatho ye-imidazolium (1100 ukuya kwi-600 cm-1) kwi-IL (21) iyanyamalala kakhulu kunyango, ebonisa ukuba i-IL electrolyte iguqulwa ngokwekhemikhali kwi-Al interface (Fig. 1A). Uhlalutyo lwe-XPS lwe-Pristine ye-Al kunye ne-TAl inikeza ulwazi olongezelelweyo kwiimpawu zemichiza ye-TAl. Iziphumo kwi-Fig. 1B, umzekelo, zibonisa ukuba nasemva kokupolisha, i-Al2O3 isalawula i-chemistry ye-Pristine Al. Ngokwahlukileyo, i-Al2p XPS spectra ye-TAl substrate ityhila ukuba indibaniselwano enamandla amakhulu okubopha, enokuthi ibalelwe kwityuwa ye-Al, ekunokwenzeka ukuba i-AlCl3, iyongamela. Oku kungqinwa yi-Cl2p XPS spectra, kuba amandla okubopha e-Cl2p abekwe malunga ne-199 eV ahambelana ne-valence ye- -1 (Fig. 1C). I-N1s XPS spectra ikwabonisa ukuba i-interface ye-TAl ityetyiswe kwiintlobo ezine-nitrogen. Incopho ebukhali kwi-401 eV ingasetyenziselwa ukuchonga ngokucacileyo ubukho be-ion imidazole (Umfanekiso 1D). Xa kuthelekiswa nomphezulu ocwebezelayo we-Al (Fig. 1E), i-topography ye-TAl ngokucacileyo igudile (Fig. 1F). Ukususela kumbono wecandelo elinqamlezayo eliboniswe yi-SEM, i-interfacial layer ibonwa kwi-Al substrate. Uhlalutyo lwe-EDX loluhlu lubonisa ukuba lutyebile kwizinto i-Al, Cl, kunye ne-N (Umfanekiso we-1G kunye ne-fig. S1).

Ibhayisekile entsha yegrabile ye-WI.DE (Winding Detours) esuka kwi-Open ithatha amatayara abanzi kune-UP yasekuqaleni yenkampani ukusuka ngo-2015 kwaye ingcono kakhulu kuyo, inesantya esiphezulu kuzo zonke iintlobo zemigangatho, efakwe ngokuphathwa okukhulu kunye nobunzima obuphantsi ukusuka yoqobo isekelwe kuyo. Kodwa ithegi yexabiso iyibeka ngaphandle kwemida kwabaninzi kwaye ungayithenga kuphela njengesakhelo esinokhetho lombala omnye.

I-Vosko, SH, Wilk, L. & Nusair, M. Amandla achanekileyo okulungelelaniswa kwe-electron exhomekeke kwi-spin ye-spin-density calculations yendawo - uhlalutyo olubalulekileyo. Ngaba. J. Phys. 58, 1200-1211 (1980).

Amanye amanqaku e-hacker ephakathi yigesi esetyenzisiweyo. Kule meko i-aluminiyam (i-aluminiyam) i-brazing rods isezantsi ngokwaneleyo ubushushu bokusebenzisa iisilinda zegesi ezilahlwayo kunye ne-MAP Pro (ukutshintshwa kwe-MAPP) mhlawumbi ingcono kancinane kunePropane okoko nje iqondo lobushushu litshona ibrashi yakho ingekho nkulu kakhulu.

Kukho malunga ne-8,000 ukuya kwi-12,000 yabasebenzi besikhumba, ukunyuka ukuya kwi-15,000 kwiinyanga ezimbini okanye ezintathu emva komnyhadala we-Eid-al-Adha, ixesha lexesha eliphezulu lokulungisa izikhumba ekrwada.[3]

I-GMAW kwi-aluminiyam ixhaphake kakhulu kwiindawo zemveliso ephezulu…I-GTAW ixhaphake kakhulu kwisiphelo esiphezulu kwizicelo zesiko.

Umthi owenziwe ngamaplanga, imicu yamaplanga, nokuba uyibiza ngantoni, le nto yoyilo ilapha ukuze ihlale ngaphakathi eSingapore.

Umzobo S9. Iimpawu ze-Electrochemical zeebhetri ze-Al-MnO2 zisebenzisa i-TAl anode-, i-Al (CF3SO3) 3-, kunye ne-Al2 (SO4) i-3-based electrolyte e-aqueous.

Eso sikali sinokufikelela kuma-300kg/600lbs. Bendingalindelanga ukuba unxibelelwano lube namandla kangako ngoko ke ukuseta kwam bekungalungiswanga ngokucacileyo. Ndingathanda ukwakha indawo yokuxhoma yokuvavanya izinto ezinje kwixesha elizayo. Ndicinga ukuba ulahlekile inqaku levidiyo yam. Uninzi lwabantu aludingi unxibelelwano olunamandla ngokwaneleyo ukutsala iityhubhu ze-CF ku-2. Ndiyilwe nje indlela elula yokwenza iziphelo zentonga ezomeleleyo ezomeleleyo kwiiprojekthi zokuzonwabisa / iirobhothi.

Ukuba ufuna umkhweli okumgangatho ophezulu kwaye wenze izinto ezingaqhelekanga, kodwa awufuni kuchitha intywenka yemali, iMetrix lukhetho olundilisekileyo.
