Chemical reaction cu kan pawngkam ah a cang zungzal—na ruah tikah a fiang ko, asinain mawttaw kan thawk tikah, ar kan cawh tikah, asiloah kan dum kan cawh tikah zeizat nih dah kan tuah?
Chemical catalysis thiamsang Richard Kong nih chemical thlennak kong a ruah. “Professional tuner” rian a ttuannak ah, amah nih a chim bantukin, amah tein a chuakmi lehnak lawng si loin lehnak thar hngalh khawhnak zong a duh.
College of Arts and Sciences ah Chemistry le Chemical Biology ah Klarman Fellow pakhat a si bantukin, Kong nih cun duhmi thil a chuahter khomi chemical thlennak a chuahtertu thilri sernak ah rian a ttuan, a himmi le man a ngeimi thilri a ser, cu chungah minung cungah tthatnak a chuahpi khomi thilri zong aa tel. ngandamnak. Nithumni.
“Chemical thlennak tampi cu bawmhnak um loin a cang,” tiah Kong nih a chim, mawtaw nih thil hlun an khangh tikah carbon dioxide chuahmi kong a chim. “Asinain a har deuhmi le a har deuhmi chemical thlennak hna cu anmah tein an cang lo. Hika ah hin chemical catalysis nih rian a ttuan.”
Kong le a hawile nih an duhmi thil sining lamhruaitu dingah catalysts an ser. Tahchunhnak ah, carbon dioxide cu a dikmi catalyst thim le thlennak dirhmun hneksaknak in formic acid, methanol, asiloah formaldehyde ah thlen khawh a si.
Chemistry le Chemical Biology (A&S) Professor le Kong hruaitu Kyle Lancaster chimning ahcun, Kong lamthluan cu Lancaster laboratory “hmuhchuahnak nih a hruaimi” lamthluan he aa tlak ngai. “Richard nih a chemistry tthanchoternak caah tin hman ding ruahnak a ngei, cucu ka script ah a um bal lo,” tiah Lancaster nih a chim. "Amah nih thawngzamhca ah tampi an chimmi carbon dioxide kha a sunglawi deuhmi thil ah a thlen khawhmi thilri a ngei."
Kong le a riantuan hawi hna nih naite ah khan, thil sining cheukhat tangah, carbon dioxide kha formic acid ah a thlen khawhmi thilri pakhat an hmuh.
“Kannih cu lehrulhnak ah a sangbik kan si rih lo nain, kan system cu kan duhning in remh khawh a si,” tiah Kong nih a chim. "Cuticun, zeicahdah catalysts cheukhat cu a dang nakin rang deuh in rian an ttuan, zeicahdah catalysts cheukhat cu an chuahkehnak in an ttha deuh ti kha thukpi in kan hngalhthiam khawh. Catalysts pawl i an parameters kha kan remh khawh i mah thil hna hi zeinihdah rang deuh in rian a ttuanter ti kha hngalhthiam kan i zuam khawh, zeicahtiah an riantuan ning a rang deuhdeuh, an riantuan ning a ttha deuhdeuh tikah, molecule pawl kha rang deuh in na ser khawh hna lai."
Klarman Fellow pakhat dirhmun in, Kong nih pawngkam chungin ti lam ah a luangmi a tlangpi in hmanmi chiti nitrates kha hloh i a ttha lomi thilri ah ser dingin rian a ttuan ve, tiah a ti.
Kong nih vawlei ah hmuhmi thir, aluminium le tin tibantuk hna kha catalysts ah hmannak in hneksaknak a tuah. Thir pawl cu a man a fawi, rungrul a um lo i vawlei cung ah a tam, cucaah hmannak nih a hmunmi thil a chuahpi lai lo, tiah a ti.
“Thir pahnih pakhat le pakhat an i pehtlaihnak ah zeitindah catalysts ser khawh a si timi zong kan i zuam cuahmah lio a si,” tiah Kong nih a chim. "Framework pakhat ah thir pahnih hmannak thawngin, bimetallic system in zeibantuk lehrulhnak le lungthawh awk ngai a simi chemical kalning hna dah kan hmuh khawh lai?"
Ramlak cu hi thir pawl a tlaihmi chemical pawngkam an si – hi thir pawl nih an rian an ttuan khawhnak ding caah a biapi tukmi an si, nikhua ttha caah thilthuam ttha na herh bantuk in, tiah Kong nih a chim.
A luancia kum 70 chung ah, phunglam cu chemical thlennak tuah khawhnak ding caah thir center pakhat lawng hman ding a si, asinain a luan ciami kum hra hrawng ah khan, hi rian ah a ummi chemist pawl nih thir pahnih fonhnak kong kha chemical in siseh, naih tein siseh, an hlathlai hram an thawk. Pakhatnak ah, Kong nih, “Zalonnak degree tam deuh a pek,” tiah a ti.
Hi bimetallic catalysts nih hin chemist pawl kha an thazaang le an derthawmnak cung ah hram bunh in thir catalysts fonh khawhnak a pek hna, tiah Kong nih a ti. Tahchunhnak ah, thir center pakhat cu substrates he aa pehtlaih ttha lo nain a ttha tein a hrawh ahcun a dang thir center nih cun a ttha lo ngai in a hrawh ko nain substrates he a ttha tein aa pehtlaih khawh. Thir pahnihnak a ummi nih thir pakhatnak sining zong a hnorsuan.
"Thir center pahnih karlak ah riantuan ttinak tthatnak tiah kan timi kha na hmuh hram thawk khawh," tiah Kong nih a ti. "Bimetallic catalysis riantuannak nih a dang tein a ummi le khuaruahhar in aa thleng khomi thil cheukhat a langhter cang."
Kong nih cun thir pawl cu molecule compound ah zeitindah pakhat le pakhat an i pehtlaih timi kongah fiang lonak tampi a um rih tiah a ti. Chemistry dawhnak nih a lung a lawmhter bantuk in a phichuak zong nih a lung a thawhter. Kong cu X-ray spectroscopy ah an thiamnak ruangah Lancaster Laboratories ah an rak put.
“Cucu aa pehtlaimi a si,” tiah Lancaster nih a ti. "X-ray spectroscopy nih Richard cu a hnulei ah zeidah a cang ti le tin cu a hleiin a tthawntertu le hi chemical lehrulhnak a tuah khomi a siter ti hngalhthiam awkah a bawmh. Bu nganpi chemistry kong a hngalhnak a kau tukmi in ṭhatnak kan hmu, cu nih cun phu caah hmun thar ah innka a hun."
A dihlak in a hrampi chemistry le hlathlainak ah a ttum, tiah Kong nih a ti, cun hi lam hi Open Klarman scholarship nih a tuah khawh.
“A tlangpi in nikhat ah, laboratory ah thil sining ka tuah khawh asiloah computer hmai ah ka ṭhu kho i molecule pawl kha ka zohchunh khawh hna,” tiah a ti. “Chemical cawlcanghnak kong he pehtlai in a tlingmi hmanthlak kha a si khawh chungin hmuh kan i zuam.”
