ʻO nā kānana molekole - nā mea crystalline me ka ʻaʻahu, nā pores nui molecular - he mau mea hana nui i ka ʻoihana hou, hiki ke hoʻokaʻawale koʻikoʻi, hoʻomaʻemaʻe, a me nā hopena catalytic. ʻOiai ua lawelawe maikaʻi nā kānana "off-the-shelf" kuʻuna, ke kū nei kahi hoʻololi hoʻololi: ka piʻi ʻana o nā kānana Molecular Customized. Ke neʻe nei kēia paradigm ma waho aʻe o nā waiwai waiwai i ka noʻonoʻo ʻana a me ka pololei o ka ʻenekinia o ka sieve's architecture a me ka kemika e hoʻoponopono i nā pilikia paʻakikī ʻaʻole hiki ke hoʻoponopono ʻia i nā hopena maʻamau.
No ke aha ʻo Customization? Na Puali Hookele
Ke koi nei nā ʻoihana i nā palena, e koi ana i ka maʻemaʻe i ʻike ʻole ʻia, ka maikaʻi i nā kaʻina hana ikaika, nā ala kemika hou, a me nā hoʻonā no nā pilikia kūlohelohe. ʻO nā kānana maʻamau, i kaupalena pinepine ʻia e ka nui o ka pore paʻa, nā waiwai kemika, a i ʻole ka maʻalahi i ka fouling, hāʻule pōkole. Pono nā ʻōlelo kikoʻī e like me ka hoʻokaʻawale ʻana i nā molekole kokoke like (e laʻa, nā isomers xylene kikoʻī), e hoʻolalelale i nā hopena koho me ka liʻiliʻi o ka ʻōpala, ka lawelawe ʻana i nā meaʻai paʻakikī a i ʻole nā mea ʻai i hoʻohaumia ʻia, a me ka hoʻokō ʻana i nā koi kūʻokoʻa o nā noi e puka mai ana e like me ka hopu kalapona a i ʻole ka hoʻomaʻemaʻe hydrogen holomua.
ʻO ka Molecular Architect's Toolkit: Hoʻoponopono i ke ʻano
ʻO ka hoʻokumu ʻana i kahi kānana molecular bespoke he hana maʻalahi o ka ʻepekema waiwai a me ke kemika, e pili ana i ka hoʻoponopono pololei ʻana i kekahi mau ʻāpana koʻikoʻi:
Pore Size & Geometry: ʻO ka hana kumu. ʻAe ʻia nā ʻenehana Synthesis i kēia manawa i ka mana o ka pore anawaena (sub-nanometer a nanometer scale) a me ke ʻano (nā ala, nā cages). Hoʻoholo pololei kēia i nā moleke e hiki ke komo, hoʻopuehu, a launa pū, e hiki ai ke hoʻokaʻawale i nā hui like ʻole i hoʻokaʻawale ʻia ma mua a i ʻole ka catalysis koho koho.
Ka Papa Hana: ʻO ka neʻe ʻana ma mua o nā aluminosilicates maʻamau (zeolites), e hoʻopili ana i nā mea e like me ka titanium, tin, germanium, a i ʻole phosphorous (hana ʻana i nā aluminophosphates - AlPOs, a i ʻole silicoaluminophosphates - SAPO) hoʻololi maoli i ka ʻano kemika. Hoʻokani kēia i ke ʻano (Brønsted/Lewis) a me ka ikaika o ka acidity/basicity, koʻikoʻi no ka hana catalytic a me ke koho.
Kemika Surface & Functionality: ʻO ka hoʻololi ʻana i nā ʻili o loko ma hope o ka hoʻohui ʻana ("grafting") a i ʻole i ka wā synthesis e hoʻolauna i nā pūʻulu kūlohelohe kūikawā, nā mea metala, a i ʻole nā nanoparticles. Hoʻohui kēia i nā pūnaewele catalytic, hoʻololi i ka pilina adsorption (e laʻa, hana i ka hydrophobic surfaces), a i ʻole hiki i nā hana hou e like me ka hoʻokaʻawale chiral.
Hierarchical Porosity: ʻO ka hui pū ʻana i ka microporosity inherent (pores liʻiliʻi) me ka meso- a i ʻole macropores i hoʻolauna ʻia e hana i kahi ʻuena halihali lehulehu. Hoʻomaikaʻi nui kēia "alanui molekula" i ka hoʻopuehu ʻana no nā molekala nui, pale i ka paʻa ʻana o ka pore, a hoʻonui i ka pono, ʻoi aku ka maikaʻi ma nā kaiapuni viscous a i ʻole me nā reactants nui.
ʻO ka Crystal Size & Morphology: ʻO ka hoʻomalu ʻana i ka nui o nā ʻāpana (nano vs. micro) a me ke ʻano o waho e hoʻoikaika i ka lōʻihi o ka laha ʻana, ka nui o ka paʻi ʻana i nā reactors, ka ikaika mechanical, a me ka launa pū ʻana me nā mea hoʻoulu waho.
ʻO ke ʻano a me ka hoʻohālike: nā alakaʻi koʻikoʻi
ʻAʻole kuhi hewa ka hoʻolālā ʻana i nā kānana maʻamau. ʻO ka hōʻailona koʻikoʻi ka mea nui: X-ray Diffraction (XRD) hōʻoia i ka hana aniani; Hōʻike ka Electron Microscopy (SEM / TEM) i ka morphology; ʻIke pololei ke kinoea Adsorption Analysis i ka nui o ka pore a me ka ʻili o ka ʻili; Nānā ʻo Spectroscopy (IR, NMR) i nā wahi kemika a me nā wahi hana. He mea koʻikoʻi ka kemika computational a me ka aʻo ʻana i nā mīkini, e wānana ana i ka adsorption, diffusion, a me nā ʻano hana pane i loko o nā hale virtual a me ka wikiwiki i ka loaʻa ʻana a me ka hoʻomaikaʻi ʻana i nā mea hou ma o ka nānā ʻana i ka nui o ka synthesis-property datasets.
ʻO kēia hiki ke hana ma ke ʻano he molecular architects, hoʻolālā ʻana i nā kānana me ka pololei o ka ʻokiʻoki no nā hana kikoʻī, hōʻailona i kahi holomua hohonu. Wehe ia i nā mea hiki ke holomua ma nā kahua he nui, e neʻe ana mai ka ʻike serendipitous i ka hoʻolālā kūpono o kēia mau kānana ikaika a ʻike ʻole.
