Tooj liab ua npuas ncaujyog ib yam khoom tshwj xeeb uas muaj qhov ntxeem tau zoo heev thiab sib cuam tshuam cov qauv. Cov qauv ntawm tooj liab ua npuas ncauj muaj cov ncej ruaj khov thiab lub network ntawm lub hlwb qhib, uas muab nws cov khoom tshwj xeeb thiab kev siv.

Cov ncej khoom nyob rau hauv tooj liab ua npuas ncauj yog ua los ntawm cov tooj liab ntshiab, muab lub zog thiab conductivity rau cov khoom. Cov ncej tsim muaj peb-dimensional network uas muab cov tooj liab ua npuas ncauj nws cov qauv kev ncaj ncees thiab tso cai rau nws tiv taus qhov kub thiab txias. Cov struts tseem muab lub moj khaum rau cov khoom siv los tswj nws cov duab thiab daim ntawv, ua rau nws zoo tagnrho rau ntau yam kev siv engineering thiab kev lag luam.

Ntxiv nrog rau cov ncej khoom, tooj liab ua npuas ncauj kuj tseem qhib hlwb faib thoob plaws hauv cov khoom. Cov hlwb qhib no muab cov tooj liab ua npuas ncauj siab porosity thiab tsawg ntom, ua rau nws lub teeb yuag thiab permeable heev rau gases thiab kua. Qhib hlwb kuj txhim khu thermal thiabacoustic rwb thaiv tsev, ua tooj liab ua npuas ncauj haum rau ntau yam thermal thiab acoustic daim ntaub ntawv.

Cov qauv sib txuas ntawm tooj liab ua npuas ncauj, nrog nws cov ncej muaj zog thiab qhib qhov pores, muab cov khoom siv nrog thaj tsam loj, uas ua rau cov txheej txheem catalytic thiab pom. Copper ua npuas ncauj qhov siab ntawm thaj tsam rau qhov ntim qhov sib piv ua kom muaj kev sib cuam tshuam ntawm cov khoom siv thiab nws qhov chaw nyob ib puag ncig, ua rau nws muaj txiaj ntsig zoo rau cov tshuaj tiv thaiv tshuaj thiablim zoorau cais cov khoom ntawm cov kua.

Zuag qhia tag nrho, tus qauv ntawmtooj liab ua npuas ncaujua rau nws muaj ntau yam khoom siv thiab muaj txiaj ntsig rau ntau yam kev lag luam. Nws qhov tshwj xeeb ua ke ntawm cov ncej ruaj khov thiab qhib qhov pores muab nws lub zog zoo dua, kev ua tau zoo, permeability thiab thaj chaw saum npoo, ua rau nws tsim nyog rau kev siv xws li cov khoom siv hluav taws xob, cov hloov pauv catalytic, lim thiabacoustic vaj huam sib luag. Nrog kev nce qib tshiab hauv kev tsim cov tooj liab ua npuas ncauj, nws cov qauv yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev qhib nws lub peev xwm tag nrho rau kev siv yav tom ntej.
