Uninzi lweeklasi zesayensi ezikolweni nakwiiyunivesithi zifuna iikhemikhali ezinokutsha zokwenza iimvavanyo. Ukuthintela iingozi zengozi, kubalulekile ukuba uzigcine kwiikhemikhali ezinokutsha.

Itekhnoloji ye-Yunboshiineminyaka engaphezu kwe-10 yamava njengenkokeli ekwenzeni izinto ezinobungozi ezitori. Sinikezela ngomgca opheleleyo weekhavathi zokugcina ezinokutsha kunye nobukhulu obahlukileyo kunye nemibala. Iikhabhathi zokhuseleko ezinokutsha zizinto ezibalulekileyo kwiilebhu zesayensi, kunye netekhnoloji yunboshi ikunika itekhnoloji yokhuseleko.
