Emkhathini oguqukayo njalo wesayensi yezinto zokwakha, izisefo zamangqamuzana ziye zavela njengento eqanjiwe, eqhuba buthule inqubekelaphambili ezimbonini kusukela ekukhiqizeni amandla kuye kwezokunakekelwa kwempilo. Lezi zinto ezincane, ezinezikhala ezinkulu azizona nje izimangaliso zesayensi kodwa futhi amathuluzi abalulekile ekubhekaneni nezinselele ezicindezela kakhulu zomhlaba wanamuhla. Njengoba izicelo zabo ziqhubeka nokwanda, izisefo zamangqamuzana zibonakala ziyisisekelo sokusungula izinto ezintsha, ezivumela izinqubo ezihlanzekile, ezisebenza kahle kakhulu neziqhubekayo emikhakheni eminingi eminingi.
Yiziphi Izisefo Zemolekyuli?
Izisefo zamangqamuzana ziyizinto ezinezimbotshana ezincane ezingakhanga ama-molecule ngokuya ngosayizi nokuma kwawo. Ivamise ukwakhiwa ngenhlanganisela esekwe ku-aluminium noma nge-silicon, lezi zinto zisebenza njengezihlungi zamangqamuzana, ezivumela ama-molecule amancane ukuthi adlule ngenkathi ebamba amakhulu. Lesi sakhiwo esiyingqayizivele sibenza babaluleke kakhulu ekuhlanzeni, ekuhlukaniseni, nasezinkambisweni ze-catalysis. Izisefo zamangqamuzana zisetshenziswa kakhulu ezimbonini ezifana nokukhiqiza amakhemikhali, amakhemikhali e-petrochemicals, ezemithi, ukudla nesiphuzo, kanye nokuvikelwa kwemvelo.
Iqhaza Lezisefo Zemolekyuli Embonini
Ukuvikelwa Kwemvelo: Izisefo zamangqamuzana ziyingxenye ebalulekile ezinhlelweni zokuhlanza umoya namanzi. Asebenza kahle kakhulu ekususeni ukungcola okuyingozi okufana ne-volatile organic compounds (VOCs), izinsimbi ezisindayo, nokunye ukungcola okuvela ezimbonini nasemanzini angcolile. Lokhu kubenza babaluleke kakhulu ekulweni nokunukubezeka kanye nasekukhuthazeni izindlela ezisimeme zemvelo.
Izimboni Zamakhemikhali Nezamafutha: Kulezi zimboni, izisefo zamangqamuzana zisetshenziswa njengezisusa noma izisekelo ze-catalyst ekuphenduleni kwamakhemikhali. Isakhiwo sabo esinezimbotshana sinikeza indawo ekahle ukuze ama-catalyst anamathele kuso, athuthukise ukusebenza kahle kokusabela nokukhetha. Zibuye zisetshenziselwe ukususa ukungcola kumagesi kanye noketshezi, ukuqinisekisa ukukhiqizwa kwemikhiqizo ehlanzekile kakhulu.
I-Pharmaceuticals and Biotechnology: Izisefo zamamolekyuli zidlala indima ebalulekile ekuhlanganiseni nasekuhlanzweni kwezidakamizwa kanye nesayensi yezinto eziphilayo. Amandla abo okukhangisa ngokukhetha ama-molecule athile awenza abebalulekile ekuqinisekiseni ikhwalithi nokuphepha kwemikhiqizo yezemithi.
Imboni Yokudla Neziphuzo: Izisefo zamangqamuzana zisetshenziselwa ukususa ukungcola nezinto ezingafuneki emikhiqizweni yokudla naseziphuzweni. Isibonelo, baqashwe ekuqedeni amanzi emzimbeni wezinto zokudla kanye nokususwa kwama-flavour namaphunga, okuqinisekisa ukuzinza kanye nekhwalithi yemikhiqizo yokudla.
Ukuhlukaniswa Kwegesi Nokugcinwa: Izisefo zamangqamuzana ziyingxenye yokuhlanzwa kwamagesi ezimboni njenge-nitrogen, umoya-mpilo, negesi yemvelo. Asetshenziswa futhi ekugcineni amagesi, okuhlanganisa i-hydrogen, ngokuwakhangisa ngaphakathi kwezimbotshana zawo.
Ama-Sieve Emangqamuzana Amandla Nokusimama
Isidingo esikhulayo samandla ahlanzekile kanye nobuchwepheshe obuqhubekayo buye baphakamisa ukubaluleka kokusefa kwamangqamuzana. Asetshenziswa ekukhiqizeni uphethiloli we-hydrogen, lapho asiza khona ukuhlanza nokugcina igesi ye-hydrogen. Ukwengeza, izisefo zamangqamuzana zicutshungulwa amandla azo kutheknoloji ye-carbon capture and storage (CCS), okuhloswe ngayo ukunciphisa ukukhishwa kwesisi esibamba ukushisa ngokubamba i-carbon dioxide ngaphambi kokuthi ikhishelwe emkhathini.
Ikusasa Lama-Sieve Emangqamuzana
Njengoba izimboni ziqhubeka nokuvela, isidingo sezisefo zamangqamuzana kulindeleke ukuthi sikhule, siqhutshwa amandla azo okubhekana nezinselele eziyinkimbinkimbi ekuhlanzeni, ukuhlukaniswa, kanye ne-catalysis. Abacwaningi bahlola ngenkuthalo izinhlelo zokusebenza ezintsha, ezifana nokusebenzisa izisefo zamangqamuzana ezinhlelweni zokuhlunga amanzi ukuze banikeze amanzi okuphuza ahlanzekile ezindaweni ezikude. Ngaphezu kwalokho, intuthuko ku-nanotechnology ivumela ukuthuthukiswa kwezisefo zamangqamuzana enziwe ngokwezifiso kakhulu ezinezimbobo ezenziwe zafanelana, okuvula amathuba amasha ekulethweni kwezidakamizwa, i-catalysis, kanye nobuchwepheshe benzwa.
Isiphetho
Izisefo zamangqamuzana zingaphezu nje kwethuluzi lobuchwepheshe; ziyisisekelo sezimboni nobuchwepheshe besimanje. Amandla abo okukhangisa nokuhlanza ama-molecule abenze babaluleke kakhulu emikhakheni ehlukahlukene njengokuvikelwa kwemvelo, ukunakekelwa kwezempilo, kanye nokukhiqizwa kwamandla. Njengoba isayensi nobuchwepheshe buqhubekela phambili, izisefo zamangqamuzana zilungele ukudlala indima ebaluleke nakakhulu ekulolongeni ikusasa elisimeme nelisunguliwe. Ngokuguquguquka kwazo nokuvumelana nezimo, izisefo zamamolekyuli zisethwe ukuthi zihlale zihamba phambili kwezesayensi yezinto ezibonakalayo, eziqhuba inqubekelaphambili kanye nokwenza ngcono izinga lempilo emhlabeni wonke.
