Hi capar hi Science X i editorial phunglam le phunglam ningin zohfel a si. Editor pawl nih a tanglei sining hna kha biapi ah an chiah i a chunglei a hmaanmi a si lai ti kha an hngalh:
Khuacaan thlennak cu vawleicung pumpi nih biapi ah chiah a herhmi thil biapi pakhat a si. Vawleicung ram kip nih vawleipumpi lumnak le khuacaan thlennak nih a chuahpimi thil zorternak ding caah phunglam an ser. Tahchunhnak ah, European Union nih 2050 tiang ah khuacaan thlennak hmuh khawhnak ding caah a tlingmi lamhruainak a chuahpi. Cu bantuk cun, European Green Deal nih greenhouse gas chuahmi zorternak kha a biapi ah a chiah.
A chuakmi carbon dioxide (CO2) tlaih i chemical hmangin chawlehnak thilri ah thlen cu vawleipumpi lumnak tlawmternak le a chuahpimi thil zorternak lam pakhat a si. Scientist pawl nih a tu ah carbon tlaih khawhnak le hmannak (CCU) thiamnak kha man tlawm tein carbon dioxide chiahnak le thlennak karhternak caah ruahchannak a ummi lam pakhat in an kawl cuahmah lio a si.
Sihmanhsehlaw, vawleicung CCU hlathlainak cu a tlangpi in aa thlengmi thilri 20 hrawng lawng ah a tlawm. CO2 chuahnak a phunphun ruangah, a kau deuhmi compound hmuh khawhnak cu a biapi tuk, cu nih cun CO2 tlawmte hmanh ah a thlen khawhmi thil kalning kong ah thukpi in hlathlainak a herh lai.
Korea ram Chung-Ang University in hlathlaitu phu pakhat nih CCU kalning kong hlathlainak an tuah i cu hna nih cun thilri rawhralnak asiloah a rummi thilri hna kha sipuazi lei in a ttha khawhnak hnga thilri ah an hman.
Professor Sungho Yoon le Associate Professor Chul-Jin Lee nih an hruaimi hlathlainak phu nih naite ah khan chawlehnak caah a ttha ngaimi thilri pahnih: calcium formate chuah khawhnak ding caah calcium le magnesium a tammi a tlangpi le a tlangpi in a ummi lungpang, riantuannak carbon dioxide le dolomite hmannak kong hlathlainak an chuah. le magnesium oxide.
"Carbon dioxide hmangin thil mansung chuah khawhnak ding caah lungthawhnak a karh chin lengmang i cu nih cun khuacaan thlennak nih a chuahpimi thil sining hna kha a zorter khawh i cu nih cun sipuazi ṭhatnak a chuahter. Carbon dioxide hydrogenation reactions le cation exchange reactions pawl fonh in, thir oxides le mansungmi formates chuah khawhnak ding caah thil kalning hna kha caankhatte ah thianh khawhnak lam pakhat kan ser," tiah Professor Yin nih a chim.
An hlathlainak ah, scientist pawl nih catalyst (Ru/bpyTN-30-CTF) hmangin carbon dioxide ah hydrogen an chap, cu nih cun man a ngeimi thilri pahnih a chuahter: calcium formate le magnesium oxide. Calcium formate, cement cawhmi, daicer, le saram rawl cawhmi zong savun tannak ah hman a si.
Cu he aa dang in, magnesium oxide cu saknak le sii lei riantuannak ah tampi hman a si. Hi thil kalning hi a si kho lawng si loin a rang tuk, innchung lumnak ah minutes 5 chung lawng ah thilri a chuah khawh. Cun, hlathlaitu hna nih hi thil kalning nih hin calcium formate chuahnak phunglam he tahchunh tikah vawleipumpi lumnak 20% in a zorter khawh tiah an tuak.
Team nih cun an phunglam nih a um cangmi thilchuah ningcang hna kha a thlen khawh lai maw ti zong kha pawngkam cung i a chuahpimi thil le sipuazi a tthatnak kong hlathlainak in an zohfel cuahmah. “A phichuak cungah hram bunh in, kan tuah ning cu pawngkam caah a ttha mi carbon dioxide thlennak lam dang a si tiah kan ti khawh i, cu nih cun hlanlio thil tuah ning kha a thlen khawh i, riantuannak hmun i carbon dioxide chuahmi zorternak ah a bawmh khawh,” tiah Professor Yin nih a fianter.
Carbon dioxide kha thilri ttha ah thlen cu ruahchannak a um ko nain, hi thil kalning hna hi tthanchoter a fawi zungzal lo. CCU thiamnak tam deuh cu chawlehnak ah hman an si rih lo, zeicahtiah an sipuazi tthatnak cu a tlangpi chawlehnak kalning he tahchunh tikah a niam. “Pawngkam le chawlehnak caah a ṭhami siter awkah CCU kalning le thilri hman ṭhannak kha kan fonh a hau. Hi nih hin hmailei ah net-zero emissions tinhmi tlinter khawh a si lai,” tiah Dr Lee nih a donghter.

Cafang palh, a dik lomi, asiloah hi cahmai ah a ummi remh ding in nawlnak na tuah ahcun, hi form hi hmang. Biahalnak tlangpi caah, kan pehtlaihnak ca kha hmang. A tlangpi ruahnak cheuhnak caah, a tanglei mipi ruahnak cheuhnak ṭhen kha hmang (lamhruainak kha zulh).
Na ruahnak hi kan caah a biapi. Sihmanhsehlaw, cakuat a tam tuk caah, pumpak lehnak kan in kamh kho hna lo.
Na email address cu email a kuatmi a cohlangtu hna chimh awk lawng ah hman a si. Na address siseh, a cohlangtu address siseh, thil dang caah hman a si lai lo. Na khumhmi thawngpang cu na email ah a lang lai i Phys.org nih zeibantuk phun hmanh in a chiah lai lo.
Na inbox ah zarh fatin le/asiloah nifatin thawngpang thar hmuh. Zeitik caan paoh ah na chuah khawh i na konglam kha midang sinah kan hrawm bal hna lai lo.
Kan konglam cu mi vialte nih hmuh khawh dingin kan tuah. Science X riantuannak kha premium account in bawmhchanh ding kha ruat.
