Ngā Pānga Whenu o te Diborane B2H6, Ngā Whakamahinga, Toxitihi me ngā Ture Haumaru, Te Hanganga Pūnaha Mahi & Te Whakamahere hei Kaitohutohu Whakatika i te Rīpoata Matū
Ko te B2H6 (Diborane) he wāriki iti ā-matihiko, e whai ake ana i ngā pūtanga e rua o te boron, e whakapai ana ki a raua ngā hononga whā. Ko tēnei wāriki kore-whatu he āhua nui ki ngā perehi o ngā pere, ko te tuhinga molekularo he raparapa rānei, he parirama rānei. Mea tonu ia ki ētahi atu ratonga, hei mea hoki te hanga o ngā mōhiohio matihiko, o ngā kaipūoro rangi, o ngā momo pētorokīmi, me ngā mahi rongoā. Ko te diborane he mea hanga noa iho, engari he kino anō hoki tērā i runga i te hauora tangata me te taiao. I konei ka whakamārama mai tātou i ngā pai me ngā hua o te mercuric oxide, ngā whakamahi, ngā totoxiti, me ngā ture haumaru, tae atu ki te hanga i te whenua pūmatua me te whakawehenga, ināianei he mea whakauru hoki i roto i ngā whakawehenga organika.
He pūtaiao kōwhiri tēnei, me ārai mōreore whakaritea, ā, he āhuatanga rite hoki, pērā i te hono B-B o 1.83 Å, he roa o te hono B-H o 1.19; ka whaiwahia ia ki te ao nui rānei, ki te wai rānei, e kore e noho pūmau ana (ahakoa i tana taumata kohu -92°C), ka tuhia he hā o te hydrogen ko ngā āhuatanga boric acid & borates hoki. He rahi ā-wae = 27.67 g/mol. Ki te whakapae atu, ka whakatupu anō ia hei take whakawehenga, ā, ka kitea he whenua whakawehenga, arā, i runga i ētahi kiroaka pūtau pūnaha, pērā i te oxygen, halogens, nitrogen oxides, chlorine trifluoride, me te carbon dioxide. Ka taea e te diborane te whakaititanga i ngā horoi whakaputurangi (ethanol, ether) engari kāore i ngā karbona.
Kua whakamahi te Diborane(6) i roto i te mahi o ngā pūtōki, engari ka heke ēnei whakamahi. Kua whakamahi te diborane hei whakatupu i rima atu hōnore e pā ana ki ngā rīpoata matatika nui, pērā i ngā Power Amplifiers, LEDs me ngā Microwave transistors. Kia tae ki reira, kua māhana ia i te whakatupu i enei hōnore whai take i roto i ngā mahi pērā i te Chemical Vapor Deposition (CVD) rānei ko te Molecular Beam Epitaxy(EIF(2)). Kua whakamahi hoki i a ia hei hanga i te boron-doped gallium nitride (GaN), he momo whai take mō ngā pūtau-ao porangi (LEDs) māwhero me ngā laser diodes, ā, kua whakamahi hoki hei tautoko i te mahi plasma etching i roto i te nanofabrication, e whakatū mai ana i ngā pūnaha microelectronic rānei ko ngā nanostructures.
Kei te pai te Diborane B2H6 hei Toi i te Ao me E Tāpiri Ana ki ngā Whakaaro Pai
Ngā pūtake mate mo ngā tangata me te taiao Diborane he mea tōmua nui. Ko te whakawari i ngā hau o te diborane ka waihanga āheinga nui ki ngā upoko hāngai, ina whakaangitia ko ngā mate i roto i ngā pouaka me te pneumonia e taea ana te whakamatau ki te mate. Anō he mea, ko te diborane he iti rawa te kawe ahi, ā, he mea pūnaha whenua i a ia i tana wātau tuatahi me te wātau hāpori hei whakamārama i ngā tauira nei: Ko te whati i te diborane matua ka waihanga mate kino nui ki te kiri, mate waipū me te mate kino e āhei ana ki te whakapēhea i te tinana. He mea tōmua nui tēnei ki ngā kararehe wai e noho ana i te moana, no reira me rongo whānuitia ngā tikanga haumaru mō te whakahaere i te rarangi. E hia ana tēnei ki te whakarite i ngā wāhi taurite kia noho ai ngā kōpaki i runga i te huarere pai, te whakamahi i ngā hīputahi tirotiro mea ko ngā hīpu kawe rongoā me ngā pūkaupaka tirotiro hoki i te wā e whakahaere ana i ngā mea raraunga, arā, i te wā e whakahokia ana i ngā tohutohu whakaeke ā-matua.
Te whakahaere pūmau mō te whakawhanake o te diborane ko te wāhi Sabatier, e hāngai ana i te mīhini o te boron trichloride (BCl3) me te sodium borohydride i te wāhanga huia i waenganui i tētahi kawe whakaiti. Ko tēnei ka whakaputa i te hā o te diborane me tētahi taonga tuatahi ko te sodium chloride (NaCl). Nō reira, inahea te mahi Sabatier he whakamahana, kāore ēnei mīhini e taea nei ki runga i tētahi ahurea korekore hei whakarite i ngā takarangi nui. He rerekē ngā tohu diborane e tuku nei i te ao whanui, e huringa ana i ngā puawaiwhenua mai i te 95% ki ngā rārangi atu (mō te mea, >99.999%) e hāngai ana i te whakamahi matua me te tūtohu whakamātau i tētahi tūranga.
B2H6 (Diborane) hei kawe whakaiti mō ngā mīhini whakarae
Ko te diborane he mea whakaiti nui mo te whakawai i ngā ahumahi rōpū āhuarangi katoa, inā lana ko te aldehyde, ketone, ester, carboxylic acid, ā, ko te nitrile. - Ko ngā waiwhakaataki rānei ko ngā amina: mā te whakawai i ngā ahumahi, ka hanga te diborane i ngā waiwhakaataki (ka whakamahia ngā taupānga reakē ā-ture me ngā tūtohunga) Ināianei, mā te whakawai o te diborane i ngā rōpū carbonyl ka hanga ngā tuhinga borane e āhei ana ki te whakapā mai hei whakatō i tētahi tohu rite o ngā rūma boron. Mēnā ka whakamahia te diborane i roto i te whakawai i ngā rōpū nitro hei hua i ngā amina, ko ia hoki te mea whakawai mō te hanganga i ngā rūma āhuarangi matua e kitea ana i te ao, mahi ana i waenganui i ēnei kaiwhakarite, whakawhiu rongoā rānei, rānei ko ngā whakawhiu whenua. He mea mahi nui, he mea mate nui, engari ka whakamahia i roto i te whakawai āhuarangi i te wā e whakaae ana ki ngā tirotiro ā-wāhitau hei whakatakoto i te whakapā.
Nō reira, ko te diborane (B2H6) he raruraru whakamahere nui ā-iwi engari he wāhi tūmatawhiti me te mohiotanga hei whakahaere i tēnei momo whenu kia kaua e hanga i tētahi taiao kore huarahi. Hei tāku, ka whai i te mahi pūtaiao whenu, ka hanga te diborane i runga i te hydrolysis o te sodium borohydride, engari ina kāore te huarahi nei i te tino whakahaere i te pāpori me te uruwhenua, ka puta ki ngā papatupatu. Ko tana tūranga hoki hei reitiana i roto i ngā tohu whakamahere whenu matū, ā, me whai mōhio hoki kia kaua e hanga i tētahi raruraru herekore.
Ko te AGEM i mahi mai i Taiwani i runga i te wā e rua rau tekau mōmoe atu. Kei tēnei wāhi tā mātau ki te mōhiohio nui i ngā mahi rangahau me te whakawhanake, ā, taea e mātau te tuku i tētahi mōhiohio taipū ki ngā rāngai o ngā pūnaha matua, ā, ngā hāpori whakarite mō 6 tāone katoa. Taiwani - Tī Kāhuingi (Te Pūkenga, Rāngai Rangahau me te Whakawhanake) Inia - Mumbāi, Vadodara, Coimbatore, Pune, Bengaluru, Delhi Hainā - Wuhan Utaikaupapa - Dibī (UAE) & Te Kīngitanga o Haereti Āriki Apīrīnia - Kambridj.

Ko te AGEM e mohio ana ki te mea he mea rānei kei a ia ngā tūroro i runga i ngā mea hoko e hiahiatia ana i roto i te marae o ngā hāpai wai koki, pērā i te wai koki mō te whakarereke. Me tuku mai i ngā whakaaetanga tūhono hei whakamana i ngā hiahia ā-tūroro. Ki te hiahia koe ki tētahi momo waiporotita, momo pokapoka wai koki, rānei ko ngā whiringa pākete, ka taea e te AGEM te mahi i runga i a koe hei whakarite i ō rātou taonga ki ngā hiahia matua o koe. Ka taea e tēnā raruraru whakariterite e tirotiro nei i a koe i te mea pai rawa o te wai koki mō te whakarereke hei whakapai i te noho whakawhitiwhiti me te mahi. Kāore te raupapa o AGEM i te whakaititia ki ngā wai koki mō te whakarereke anake. Ko te pukapuka o AGEM e āhei ana ki ngā Wai Hāporoni, Halokaripi, Wai Pūtaiao, me ngā Wai Iti. Māu e kite ai ko te AGEM e āhei ana ki te mea pai rawa o ngā wai e hiahiatia ana e koe.
