20 de may. de 2024 · The chemists Peter Debye and Erich Hückel noticed that solutions that contain ionic solutes do not behave ideally even at very low concentrations. So, while the concentration of the solutes is fundamental to the calculation of the dynamics of a solution, they theorized that an extra factor that they termed gamma is necessary to the calculation ...
Hace 1 día · The Debye–Hückel theory was proposed by Peter Debye and Erich Hückel as a theoretical explanation for departures from ideality in solutions of electrolytes and plasmas. [1] It is a linearized Poisson–Boltzmann model , which assumes an extremely simplified model of electrolyte solution but nevertheless gave accurate predictions of mean activity coefficients for ions in dilute solution.
Hace 4 días · The Debye–Waller factor (DWF), named after Peter Debye and Ivar Waller, is used in condensed matter physics to describe the attenuation of x-ray scattering or coherent neutron scattering caused by thermal motion. It is also called the B factor, atomic B factor, or temperature factor.
Hace 5 días · They found the gold enhances the adsorption across a surprisingly large area of the semiconductor’s surface – more than a micrometer away from the source. The discovery could increase the efficiency of photocatalysis for eliminating micropollutants in wastewater. The findings were published July 19 in Nature Catalysis.
Hace 6 días · In Nederland besloot de Universiteit Maastricht geen Debye-prijzen meer uit te reiken, vanwege de rol die de naamgever – chemicus en Nobelprijswinnaar Peter Debye (1884-1966) – speelde bij het wegwerken van Joodse collegawetenschappers. Een naar Debye vernoemd onderzoeksinstituut in Utrecht hield wél zijn naam, na onderzoek door een commissie.

Folge von „Auf einen Kaffee mit…“, dem Wissenschaftspodcast ...
