Hauv kev tshawb fawb tshuaj thiab cov ntaub ntawv, kev nkag siab txog cov kab uas hla ntawm cov roj sib txawv yog qhov tseem ceeb rau kev tsim cov molecular sieves, adsorbents, thiab optimizing cov txheej txheem roj sib cais.
Hauv qab no yog qee cov ntaub ntawv kab mob molecular rau cov khoom siv tshuaj, tag nrho hauv nanometers (nm).
Cov ntaub ntawv no yog ua raws li cov ntaub ntawv tshawb fawb thiab kev kwv yees, thiab yog npaj los ua ib qho kev siv rau cov kws tshaj lij hauv kev lag luam ntsig txog.
Cov hauv qab no yog cov kab mob molecular ntawm cov khoom siv / tsis tshua muaj roj thiab cov khoom siv tshuaj lom neeg:
