Example Sentences

By the donor doping of large W6+, this material can take up more water to increase its proton concentration, as well as reduce the proton trapping through electrostatic repulsion between the dopant and proton.

From Science Daily

"A major problem with the conventional proton conductors is a phenomenon known as proton trapping, in which protons are trapped by acceptor dopant via electrostatic attraction between the dopant and proton," explains Yashima.

From Science Daily

As for proton trapping, the high positive charge of the W6+ dopant leads to a stronger repulsion with protons, which are also positively charged.

From Science Daily

The repulsion indicates reduced proton trapping by the W6+ dopant, which leads to the high proton conductivity at low and intermediate temperatures.

From Science Daily

"The stabilization of perovskites with disordered intrinsic oxygen vacancies and full hydration enabled by doping of large donor dopant could be an effective strategy towards next-generation proton conductors," remarks Yashima.
