Chemia w ograniczonej geometrii

Tematyka badawcza
Nasze badania dotyczą uwięzionej materii. Jesteśmy ciekawi w jaki sposób cząsteczki oraz większe cząstki zachowują się w ograniczonej przestrzeni tworzonej przez nie. Szczególnie jesteśmy zainteresowani w wykorzystaniu tych przemian zachodzących samoczynnie lub pod wpływem bodźców zewnętrznych - do samoorganizacji, katalizy oraz wytwarzania funkcyjnych systemów.

Effective screening of Coulomb repulsions in water accelerates reactions of like-charged compounds by orders of magnitude.
Nature Communications, https://doi.org/10.1038/s41467-022-34182-z
The reaction speed of like-charged compounds in water is extremely slow due to Coulomb repulsions. Here, the authors boost kinetics up to 5 million times by screening these interactions and increasing the local concentration of reactants using positively charged micelles. They show the effect of two independent systems and present a theoretical explanation.
