Electron tunneling associated with ferritin was proposed as early as 1988, but it is still viewed skeptically despite substantial evidence that it occurs. In our recent paper published in IEEE Transactions on Molecular, Biological ...
Chemical structures called cyclopropanes can increase the potency and fine-tune the properties of many drugs, but traditional methods to create this structure only work with certain molecules and require highly reactive—potentially ...
