I-nanotechnology igatsha lesayensi elithuthuka ngokushesha elithembisa ukuguqula imikhakha efana nemithi, ubuchwepheshe bolwazi, amandla, kanye nemvelo. Igama elithi "nanotechnology" libhekisela ekuphathweni kwezinto esikalini se-nanometer, ingxenye eyodwa kweziyizigidigidi zemitha, okuvumela ososayensi ukuthi bakhe futhi balawule izakhiwo ngokunemba okumangalisayo. Lesi sihloko sizochaza… Funda kabanzi
I-Chemistry iwukufunda izakhiwo, ukwakheka, kanye nezinguquko zezinto. Njengoba isayensi ithuthuka, ososayensi bakhe imithetho eminingana eyisisekelo esekela yonke imibono yamakhemikhali kanye nokusetshenziswa kwawo. Le mithetho ayibalulekile nje kuphela ekuqondeni okuyisisekelo kwe-chemistry kodwa futhi iwusizo kakhulu ekusetshenzisweni okuhlukahlukene okusebenzayo kwezobuchwepheshe, kwezemithi, kanye nemvelo. Lesi sihloko sizo… Funda kabanzi
Ukusabela kwamakhemikhali inqubo lapho into eyodwa noma eziningi ziguqulwa zibe yinto eyodwa noma eziningi ezintsha ezinezakhiwo ezahlukene. Le nqubo ibalulekile kumakhemikhali nakwezinye isayensi ngoba iyisisekelo sezinto eziningi zemvelo kanye nobuchwepheshe. Lesi sihloko sizoxoxa ngezici zokusabela kwamakhemikhali, izinhlobo ezahlukene zokusabela kwamakhemikhali, nokuthi ungakubhala kanjani kahle... Funda kabanzi
I-green chemistry, eyaziwa nangokuthi i-sustainable chemistry, iyindlela ye-chemistry egxile ekwakhiweni kwemikhiqizo yamakhemikhali kanye nezinqubo ezinciphisa noma eziqeda ukusetshenziswa kanye nokukhiqizwa kwezinto eziyingozi. Umgomo oyinhloko we-green chemistry ukudala izinqubo ezinobungani nemvelo, ezisebenza kahle, neziqhubekayo. Lezi zimiso zibalulekile ekusekeleni imizamo yokonga... Funda kabanzi
Isingeniso: I-green chemistry, eyaziwa nangokuthi i-chemistry enobungani nemvelo, insimu ekhulayo ye-chemistry egxile ekwakheni imikhiqizo yamakhemikhali nezinqubo ezinciphisa noma eziqeda ukusetshenziswa kanye nokukhiqizwa kwezinto eziyingozi. I-green chemistry ihlose ukuvimbela ukungcola emthonjeni wayo nokudala ezinye izindlela eziphephile zabantu kanye nemvelo. Lesi sihloko sizoxoxa ngencazelo... Funda kabanzi
