9-kii Abriil, 2024, saynisyahano Shiinees ah ayaa maqaal ku daabacay joornaalka Nature Chemistry oo ku saabsan dib-u-warshadaynta alaabada daloolka leh si ay u soo saaraan shidaal tayo sare leh, iyaga oo gaarey isticmaalka hufan ee caagagga polyetylen.

Qashinka caagagu wuxuu had iyo jeer ahaa mid ka mid ah caqabadaha halista ah ee soo wajaha deegaanka caalamiga ah, iyo xaddigeeda faraha badan ee qashinka ah ayaa waxyeello weyn u geystay deegaanka. Caagagga qashinka ah, ee loo beddeli karo bacaha, xarfaha aan xaraf lahayn ee "carbon-carbon bonds" way adag tahay in la dhaqaajiyo oo la burburiyo xaaladaha heerkulka hooseeya. Daah-furkan cusub ee ay sameeyeen saynisyahano Shiinees ah ayaa keenay rajo lagu xallinayo dhibaatadan.

Sida laga soo xigtay xogta, tignoolajiyadani waxay si hufan ugu beddeli kartaa caagagga wasakhda shidaal tayo sare leh iyada oo loo marayo falcelin kiimiko oo isku dhafan oo qurux badan. Tani kaliya ma bixiso fikrado cusub oo loogu talagalay daaweynta qashinka caagga ah, laakiin sidoo kale waxay xallisaa dhibaatada tamarta yaraanta ee barnaamijyada.

Khubarada ayaa sheegay in natiijadan la filayo in mustaqbalka si weyn loogu dabaqo isla markaana kor loogu qaado horumarinta warshadaha soo kabashada caagga ah. Haddii kor loo qaadi karo si baaxad leh, kaliya ma yaraynayso wasakhowga deegaanka ee ay keento qashinka caagagga ah, laakiin sidoo kale waxay abuurtaa qiimo dhaqaale oo la taaban karo. Waxaan aaminsanahay in dadaalka joogtada ah ee saynisyahanadu, waxaan rajaynaynaa mustaqbal nadiif ah oo cagaaran.
