Incazelo: Isikhungo Sikazwelonke Sokuthuthukisa Isayensi Yokuhumusha evela e-Bethesda, MD, isizinda somphakathi, nge-Wikimedia Commons
Umklomelo kaNobel kuKhemistry walo nyaka uklonyeliswe ngokuhlanganyela uMoungi Bawendi, uLouis Brus kanye no-Alexei Ekimov “ngokutholakala nokuhlanganiswa kwamachashazi e-quantum.” Amachashazi e-Quantum angama-nanoparticles, izinhlayiya ezincane ze-semiconductor, ama-nanometer ambalwa ngosayizi phakathi kuka-1.5 kanye...
Ukuwa kwe-grapefruit kusuka ku-10 m akulimazi i-pulp, izinhlanzi ze-Arapaimas ezihlala e-Amazon zimelana nokuhlaselwa kwamazinyo angunxantathu we-piranhas, Amagobolondo esilwane sasolwandle i-abalone aqinile futhi amelana nokuphuka, ........ .. Okungenhla...
I-microscopy yezinga eliphezulu kakhulu (izinga le-Angstrom) ethuthukisiwe ekwazi ukubona ukudlidliza kwe-molecule Isayensi nobuchwepheshe be-microscopy ihambe ibanga elide kusukela u-Van Leeuwenhoek azuza ukukhulisa cishe ama-300 ngasekupheleni kwekhulu le-17 esebenzisa i-single...
Ucwaningo olusha lusebenzise ukuhlolwa kwerobhothi ukuthola uhlu olufushane lwamakhemikhali okungenzeka 'avimbele' umalaleveva Ngokusho kwe-WHO, kube nezigameko eziyizigidi ezingama-219 zikamalaleveva emhlabeni wonke kanye nokufa kwabantu ababalelwa ku-435,000 ngo-2017. Umalaleveva isifo esithathelwanayo esibangelwa...
Abacwaningi bathole indlela yokukwazi ukuklama imithi esebenza kahle ngokunikeza inhlanganisela umumo olungile we-3D obalulekile emsebenzini wayo webhayoloji. Ukuthuthuka kwezokunakekelwa kwempilo kuncike ekuqondeni i-biology yesifo, ...
Abacwaningi baye baphenya ngokokuqala ngqá ukuthi izinhlobo ezimbili zamanzi ezihlukene (i-ortho- ne-para-) ziziphatha kanjani ngendlela ehlukile lapho zibhekana nokusabela kwamakhemikhali. Amanzi ayinhlangano yamakhemikhali, i-molecule lapho i-athomu elilodwa lomoya-mpilo lixhunywa nama-hydrogen amabili...
Ucwaningo lwakamuva olushaqisayo lubonise izakhiwo eziyingqayizivele ze-graphene yezinto okungenzeka isikhathi eside ekugcineni kuthuthukiswe ama-superconductors akongayo nangokoqobo. I-superconductor yinto ekwazi ukuqhuba (ukudlulisa) ugesi ngaphandle kokumelana. Lokhu kumelana kuchazwa ngokuthi abanye...
