Optimizing proton beam therapy with mathematical models

Particle beam therapy is increasingly being used to treat many types of cancer. It consists in subjecting tumours to beams of high-energy charged particles such as protons. Although more targeted than conventional radiotherapy ...

Current generation via quantum proton transfer

NIMS and Hokkaido University jointly discovered that proton transfer in electrochemical reactions is governed by the quantum tunneling effect (QTE) under the specific conditions. In addition, they made a first ever observation ...

Fully identified—the pathway of protons

In their catalytic center, hydrogenases manufacture molecular hydrogen (H2) from two protons and two electrons. They extract the protons required for this process from the surrounding water and transfer them – via a transport ...

Repetition key to self-healing, flexible medical devices

Medical devices powered by synthetic proteins created from repeated sequences of proteins may be possible, according to materials science and biotechnology experts, who looked at material inspired by the proteins in squid ...

Using light to move electrons and protons

(Phys.org)—In some chemical reactions both electrons and protons move together. When they transfer, they can move concertedly or in separate steps. Light-induced reactions of this sort are particularly relevant to biological ...
