EnglishRadical shielding weakens C–C bond
Simulations confirm that the use of electron withdrawing groups on radicals weakens the resulting C–C bond.

EnglishStiff, light and flexible
Rigid materials cannot absorb shocks and cushioning materials are soft. Or are they?

EnglishCO2 captured in Li battery electrolyte
The polymer of thiocarbonate monomers made with CO2 turns out to be very suitable as a solid-state electrolyte in lithium batteries

EnglishMicroporous water helps reduce oxygen
When amphiphilic zeolites are used in water, the oxygen reduction reaction goes so well that the platinum catalyst is partly the limiting factor.

EnglishAtom size – not electronegativity – determines polymer stability
The stability of hydrogen-bonded amide polymers depends on which atom replaces the oxygen in the amide.
