Isithombe: I-Corn Starch Granules Micrograph

Kule micrograph enemininingwane emangazayo, isibukeli sidonswa emhlabeni we-microscopic wamagranule esitashi sombila, anikezwe ngokucacile okukhethekile nangokunemba. Sithwetshulwe kusetshenziswa isibonakhulu se-electron yokuskena, isithombe sibonisa uhlu oluminyene lwezinhlayiya ze-polyhedral, ngayinye ehlukile kodwa ehlelwe ngokuvumelana. Ama-granules abusa uhlaka, amaphethelo awo acijile kanye nezindawo ezinezici eziningi ezakha ukwakheka kwezwe okukhazimulayo okuzwakala kungokwemvelo futhi kunobunjiniyela. Ukukhanyisa kugqamile futhi kusatshalaliswe ngokulinganayo, kuveza izithunzi ezincane futhi kuvumela ukuthungwa okuphelele kanye nejometri yegranule ngayinye ukuthi kuvele ngencazelo emangalisayo.

Ama-granules ayahlukahluka ngosayizi nangomumo, nakuba iningi livumelana nesakhiwo se-polyhedral esingaguquki—okungenzeka ukuthi i-dodecahedral noma amafomu afanayo anezici eziningi. Ubuso bazo buboshiwe futhi bumaholoholo, okuphakamisa inkimbinkimbi yemvelo ephikisana nokufana kwazo. Lokhu kuthungwa akuwona nje ubuhle; libonisa ukwakheka kwangaphakathi kwama-molecule esitashi, adlala indima ebalulekile ekuziphatheni kwawo phakathi nezinqubo ezifana ne-gelatinization, ukuwohloka kwe-enzymatic, nokuvutshelwa. Ukulungiswa okuphezulu kwesithombe kuvumela ukuhlolwa okuseduze kwalezi zici, okusenza sibe ireferensi ebaluleke kakhulu yokubuka kososayensi, abaphisi botshwala, nochwepheshe bokudla ngokufanayo.

Amiswe ngokumelene nengemuva elimhlophe elimsulwa, ama-granules agqama ngokukhululeka okugqamile, amathoni awo ampunga namakhonco ayinkimbinkimbi agcizelelwa ukungabikho komsindo obonakalayo. Lesi sangemuva se-minimalist sithuthukisa umuzwa wokugxila nokulawula, kuqinisa inhloso yesayensi yesithombe. Akusona nje isithombe—kuyisifundo, isifinyezo sezakhiwo zamangqamuzana esimema ukuhlaziya nokuchazwa. Ukwakheka kuqinile futhi kuyacwilisa, kugcwalisa ifremu ngokuphelele ngama-granules futhi kudala umuzwa wesikali ozwakala usondelene futhi unwebeka.

Kumongo wokwenza ubhiya, lesi sithombe sithatha ukubaluleka okwengeziwe. Isitashi sommbila, esivame ukusetshenziswa njengesengezo lapho kugaywa utshwala, sinikeza ushukela ovubelayo owenza umzimba ube lula kanye nephunga elimnandi lomkhiqizo wokugcina. Ukuqonda ukwakheka kwe-granule kuleli zinga kuvumela abaphisi botshwala ukuthi bathuthukise izimo ze-mash, umsebenzi we-enzyme, namazinga okuguqulwa kwesitashi. Umumo wama-granules nendawo engaphezulu kuthonya ukuthi aphuka ngokushesha nangempumelelo kanjani ngesikhathi sokuphiswa, okuthinta yonke into kusukela ekuphuzweni kotshwala kuya emlonyeni. Ngakho-ke, le micrograph ayiyona nje isimangaliso sobuchwepheshe—iyifasitela lesayensi eyisisekelo yokuphisa utshwala.

Isimo sengqondo esiphelele sesithombe singokunemba kanye nelukuluku. Imema umbukeli ukuthi acabangele ubunkimbinkimbi obufihliwe bezithako zansuku zonke, ukwazisa ubuhle bezakhiwo zemvelo ezisebenza esikalini esingaphezu kokubona komuntu. Ama-granules, nakuba engabonakali, abaluleke kakhulu ngokubaluleka kwawo, akha ukuthungwa, ukunambitheka, nokusebenza kahle kwezinhlelo eziningi zokudla neziphuzo. Ngale lens, isitashi sombila siguqulwa sisuke ekubeni yi-carbohydrate ephansi sibe isihloko esimangalisayo esingokwesayensi—into ebuhle bayo bejiyomethri, ukusebenza kwayo, kanye nokutholakala kwayo yonke indawo ethule.

Lesi sithombe sime njengobufakazi bamandla okukhulisa, okubona okungabonwayo kanye nokwembula amaphethini abusa umhlaba wethu wezinto ezibonakalayo. Ivala igebe phakathi kwesayensi yezinto eziphilayo kanye nezimboni, phakathi kwenkundla nemvubelo, inikeza umbono we-molecular choreography esekela ubuciko bokwenza utshwala.
