Ngā Whakamahinga o ngā Pūhui Organophosphate Ko ngā pūhui organophosphate he rōpū matū kei roto he ngota phosphorus (P) e herea ana ki tētahi rōpū waro (e ahu mai ana i te waro). E mōhiotia whānuitia ana tēnei rōpū mō tōna tūranga nui i roto i te ahuwhenua, te hauora tūmatanui, me te ahumahi. I tētahi taha, ka āwhina ngā organophosphate ki te whakapiki i te hua kai mā te whakahaere i ngā pepeke. I tētahi atu taha, he nui te paitini o ētahi organophosphate… Pānuihia atu

He aha te Tauhohenga Matū Kinetic? I roto i te oranga o ia rā, he maha ngā wā ka kite tātou i ngā huringa e ahua māmā ana engari he uaua ngā tukanga matū. Ko te rino waikura, ko te hua pirau, ko te miraka pirau, tae noa ki te tahunga o te wahie i roto i te miihini motuka he tauira katoa o ngā tauhohenga matū. Heoi, he maha ngā wā ka ara ake tētahi pātai nui: he aha ētahi tauhohenga... Pānuihia atu

Te Mahi a te Waikawa Citric i roto i te Kai Ko te waikawa citric tētahi o ngā tāpiringa kai e kitea whānuitia ana i roto i ngā momo hua kai me te inu. E mōhiotia whānuitia ana tēnei matū mō tōna reka whakahauora, kawa hoki, ā, he mea nui ki te pupuri i te kounga o te hua. Haunga tōna reka kawa motuhake, he maha ngā whakamahinga o te waikawa citric i roto i te hangarau kai, mai i… Pānuihia atu

Ngā Tauhohenga Matū e Puta Ana i te Wā Nakunaku Ko te nakunaku he raupapa o ngā tukanga e huri ana i te kai hei ngota māmā kia taea ai te mimiti e te tinana, kia whakamahia hoki hei pūtake pūngao, hei poraka hanga, hei whakahaere hoki i ngā mahi ā-tinana. Ehara i te mea ko ngā nekehanga ā-ringa anake pērā i te ngaungau me te peristalsis tēnei tukanga, engari ko ngā tauhohenga matū hoki e whakahaeretia ana e ngā whākōkī, ngā waikawa, me ngā wai… Pānuihia atu

Te Tukanga Hanga Waikawa Whāwhā Ko te waikawa whāwhā (H₂SO₄) tētahi o ngā matū ahumahi tino nui o te ao. E kiia ana ko te "tuara o te ahumahi matū" nā te whānuitanga o ōna whakamahinga: mai i te hanga tongi phosphate me te ammonium sulfate, ki te tukatuka hinu, te whakamahine whakarewa, te hanga pākahiko waikawa-mata, ki ngā ahumahi kakahu me te rongoā. Ko te nui o te hiahia mō te waikawa whāwhā… Pānuihia atu

Te Mārama ki te Taurite me ngā Tauira Kupu Whakataki I roto i te matū, ko te huarahi e hono ai ngā ngota hei hanga i tētahi matū ka tino whakatau i ngā āhuatanga o taua matū. Ko tētahi ariā nui e whakamārama ana i te hononga o ngā ngota ko te taurite. He maha ngā wā ka kitea ngā hononga taurite i roto i ngā pūhui e hangaia ana e ngā huānga kore-whakarewa, hei tauira, te wai (H₂O), te hauhā waro (CO₂), te methane (CH₄), me ētahi atu pūhui… Pānuihia atu

Ko te Tātari Thermogravimetric (TGA) he tikanga whakaahua rauemi e ine ana i te huringa o te papatipu o tētahi tauira hei pānga o te pāmahana me/ranei te wā i roto i te hau e whakahaerehia ana. He whānuitia te whakamahinga o tēnei tikanga i roto i te matū, te hangarau rauemi, te rongoā, ngā polymer, me te pūngao nā te mea ka taea e ia te whakarato i ngā mōhiohio nui e pā ana ki te pumau o te wera, te hanganga, te ihirangi wai/whakarewa, te pirau, me...

Te Whakamahinga o ngā Ine Taumaha i roto i te Matū Ko te ine taumaha tētahi o ngā taputapu tātari tino nui i roto i te matū hou. Mā tēnei taputapu ka taea e ngā kaipūtaiao te "kite" i te hanganga o tētahi tauira i runga i ngā taumaha o ōna matūriki, inā koa ngā taumaha o ngā katote. Mā te kaha ki te tautuhi i ngā matū, te whakatau i te hanganga ngota, te ine i ngā kukū matū, tae atu ki te kite i ngā poke moroiti, kua... Pānuihia atu

Me pēhea te Whakatau i te Tau o Avogadro Ko te tau o Avogadro tētahi o ngā ariā tino nui i roto i te matū me te ahupūngao hou nā te mea he "piriti" i waenganui i te ao moroiti (ngota, ngota, katote) me te ao makroskopi (karamu, rita, mea ka taea e tātou te pauna). Mā te mārama ki te whakatau i te tau o Avogadro, ka māmā ake tā tātou mārama ki te ariā o ngā mole, te tatau i te maha o ngā matūriki i roto i tētahi matū, … Pānuihia atu

Ngā Tikanga Ine-hiko i roto i te Matū Tātari He tikanga matarohia te ine-hiko engari he mea nui tonu i roto i te matū tātari, inā koa mō te ine i ngā katote konganuku i roto i te otinga. Ka whakakotahihia e tēnei tikanga ngā mātāpono ine-hiko me te ine-kaha: ka whakatakotoria te analyte hei konganuku ki runga i te irahiko mā te ine-hiko, ā, ka paunatia te matū i puta mai hei tatau i te nui o te analyte. Nā te mea ko te hua whakamutunga… Pānuihia atu
