Mu bucuruzi bwacu bwa peteroli na gaze, umusaruro wagabanutseho 8% umwaka ushize ku gihembwe cya mbere. Impamvu zirimo kugabanuka kwa kamere hamwe no kubungabunga no gukora neza, biri gukorwa kugirango hongerwe imitungo yizewe neza mugihembwe gikurikira. Mugukora ibi ubungubu, turemeza ko dufite igice cya kabiri gikomeye kugeza uyumwaka mugihe bimwe muribi bikorwa.

Ubushakashatsi bwerekanye kandi ko imyanda y’uruhu yanduza ubutaka bwa Hazaribagh. Ubushakashatsi bwakozwe mu 1999 bwerekanye ko bwandujwe n’ibyuma bitandukanye, birimo isasu na kadmium. Yanzuye:

Imiterere nuburyo bigize interineti byakozwe kuri Al electrode muri electrolyte ya AlCl3-IL (TAl electrode) yabajijwe hakoreshejwe uburyo bwuzuye bwerekana - Fourier transform infrared spectroscopy (ATR-FTIR), scanning electron microscopi (SEM), ikwirakwiza ingufu x -yerekana spekitroscopi (EDX), na x-ray ifoto yerekana amashanyarazi (XPS). Ugereranije na Al yera, ubuso bwa TAl bukungahaye hamwe nitsinda ryimikorere (Ishusho 1A). Usibye kuba hari amatsinda ya C = N na C - H nayo ari menshi muri pristine IL electrolyte, iterambere ryinshi mumatsinda ya C = C no kuvuka kw'ibinyabuzima birimo itsinda rya C = O bigaragara kuri TAl. Ibyo kwitegereza biherekejwe no kugaragara kwa firime ihamye hejuru ya TAl. Byongeye kandi, uburyo bwo kunyeganyega bwa infragre bifitanye isano nimpeta ya imidazolium (1100 kugeza 600 cm - 1) muri IL (21) ahanini bicika nyuma yo kuvurwa, ibyo bikaba byerekana ko IL electrolyte ihinduranya imiti kuri Al interface (Ishusho 1A). XPS isesengura pristine Al na TAl itanga ubushishozi bwinyongera mubutaka bwa chimique ya TAl. Ibisubizo ku gishushanyo cya 1B, kurugero, byerekana ko na nyuma yo gusya, Al2O3 iracyiganje kuri chimie yubuso bwa pristine Al. Ibinyuranyo, Al2p XPS yerekanwe ya TAl substrate igaragaza ko ikomatanyirizo hamwe nimbaraga nyinshi zihuza, zishobora guterwa numunyu wa Al, bishoboka ko AlCl3, yiganje. Ibi birashimangirwa na Cl2p XPS yerekanwe, kubera ko ingufu zihuza Cl2p ziri kuri 199 eV zihuye nagaciro ka −1 (Ishusho 1C). N1s XPS yerekanwe kandi yerekana ko isura ya TAl ikungahaye ku moko arimo azote. Impinga ikarishye kuri 401 eV irashobora gukoreshwa kugirango tumenye neza ko hariho ion imidazole (Ishusho 1D). Ugereranije nubuso busize neza (Isanamu 1E), hejuru yubutaka bwa TAl biragaragara ko byoroshye (Ishusho 1F). Uhereye ku gice cyambukiranya amashusho cyashizweho na SEM, intera igaragara igaragara kuri Al substrate. Isesengura rya EDX ryerekana ko rikungahaye ku bintu Al, Cl, na N (Ishusho 1G na fig. S1).

Igare rishya rya WI.DE (Winding Detours) ipikipiki ya kaburimbo ivuye muri Open ifata amapine yagutse kuruta UP yambere yisosiyete kuva 2015 kandi byose ni byiza kuri yo, ifite umuvuduko mwinshi hejuru yubwoko bwose, ushyizwemo nuburemere bukomeye hamwe nuburemere buke kuva kuri umwimerere bishingiye. Ariko igiciro kirashyira kuri benshi kandi urashobora kukigura nka frameeset uhitamo ibara rimwe.

Vosko, SH, Wilk, L. & Nusair, M. Imbaraga za spin-biterwa na electron ya elegitoronike yingufu zo kubara kwizunguruka ryaho - isesengura rikomeye. Birashoboka. J. Umubiri. 58, 1200–1211 (1980).

Bimwe mubindi bice kuri hackers isanzwe ni gaze ikoreshwa. Muri iki gihe, inkoni ya aluminium (aluminium) ni ubushyuhe buke buhagije bwo gukoresha silindiri ya gaze ihendutse kandi MAP Pro (gusimbuza MAPP) birashoboka ko ari byiza cyane kurenza Propane mugihe ubushyuhe bwarohamye brazing yawe ntabwo ari nini cyane.

Hariho abakozi bo mu ruganda bagera ku 8000 kugeza 12.000, bakazamuka bagera ku 15.000 mu gihe cy’amezi abiri cyangwa atatu nyuma y’umunsi mukuru wa Eid-al-Adha, igihe cy’ibihe byo gutunganya ibihuru mbisi. [3]

GMAW muri aluminiyumu iramenyerewe cyane mubidukikije byabyaye umusaruro… GTAW irasanzwe murwego rwohejuru rwibisabwa.

Ibiti bisatuye, ibiti, ibyo wabyita byose, iki gishushanyo kirahari kugirango ugume imbere muri Singapore.

Igishushanyo S9. Ibikoresho bya elegitoroniki ya bateri ya Al-MnO2 ukoresheje TAl anode–, Al (CF3SO3) 3-, na Al2 (SO4) 3-ishingiye kuri electrolyte y'amazi.

Icyo gipimo gishobora gupima 300kg / 600lb. Ntabwo nari niteze ko amahuriro akomeye kuburyo gahunda yanjye itari yiteguye. Ndashaka kubaka kumanikwa gushiraho ibintu nkibi mugihe kizaza. Ndatekereza ko wabuze ingingo ya videwo yanjye. Abantu benshi ntibakenera guhuza gukomeye bihagije kugirango bakurure CF muri 2. Gusa nashizeho uburyo bworoshye bwo gukora inkoni yihariye ishobora gukomera cyane kubikorwa bya hobby / robotics.

Niba ushaka ingendo nziza kandi ugakora siporo idasanzwe, ariko ntushake gukoresha umutungo, Metrix nuburyo bwiza.
