Powder wettability measurement with the Washburn method. In its most general form the Lucas Washburn equation describes the penetration length ( L {\displaystyle L} ) of a liquid into a capillary pore or tube with time t {\displaystyle t} as L = ( D t ) 1 2 {\displaystyle L=(Dt)^{\frac {1}{2}}} , where D {\displaystyle D} is a simplified ...
A force balance equation known as Washburn's equation for the above material having cylindrical pores is given as: [1] ...
Cloth, treated to be hydrophobic, shows a high contact angle. The theoretical description of contact angle arises from the consideration of a thermodynamic equilibrium between the three phases: the liquid phase (L), the solid phase (S), and the gas or vapor phase (G) (which could be a mixture of ambient atmosphere and an equilibrium concentration of the liquid vapor).
Mikkel Frandsen (1892–1981) was a Danish American physical chemist noted for experiments involving chemical thermodynamics, oil, and heavy water.Also known as deuterium oxide (D 2 O), heavy water is used to produce nuclear power and is used in other nuclear applications such as nuclear magnetic resonance spectroscopy.
One example of this is a study by Washburn, Wolters, and Yates in which they used shotgun proteomics on the proteome of a Saccharomyces cerevisiae strain grown to mid-log phase. They were able to detect and identify 1,484 proteins as well as identify proteins rarely seen in proteome analysis, including low-abundance proteins like transcription ...
Arthur Lawrence Washburn, Harvard Yearbook Photo, Class of 1910. Cannon's approach to studying hunger was part of a broader trend in physiology to investigate the body's internal processes using quantitative methods. This shift towards more objective measurements was crucial in establishing physiology as a rigorous scientific discipline. [4]

Symmetries of Culture: Theory and Practice of Plane Pattern Analysis is a book by anthropologist Dorothy K. Washburn and mathematician Donald W. Crowe published in 1988 by the University of Washington Press. The book is about the identification of patterns on cultural objects.
