Charge transfer across C-H center dot center dot center dot O hydrogen bonds stabilizes oil droplets in water

Sylvie Roke, Saranya Pullanchery Sankara Narayanan, Sergey Kulik, Benjamin Rehl

The hydrophobic-water interface plays a key role in biological interactions. However, both the hydrophobic-water interfacial molecular structure and the origin of the negative zeta potential of hydrophobic droplets in water are heavily contested. We report ...

Fast remote correlation experiments for 1H homonuclear decoupling in solids

David Lyndon Emsley, Pinelopi Moutzouri, Bruno Simões de Almeida

In 1H MAS spectra, the residual homogeneous broadening under MAS is due to a combination of higher-order shifts and splittings. We have recently shown how the two-dimensional anti-z-COSY experiment can be used for the removal of the splittings. However, th ...
