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).
The club had two MVP candidates in Messi and Luis Suarez, who became the first teammates in league history to each score 20 goals in the same season. They scored 40 of Inter Miami’s league ...

SYDNEY (Reuters) -Australia's centre-left government said on Thursday it planned new rules that would charge big tech firms millions of dollars if they did not pay Australian media companies for ...
[2] H.C. Williams reviewing the book for The Mathematical Gazette said: "This interesting book is written by a mathematician and an anthropologist and is aimed primarily at the non-mathematician. That said, it is well worth the attention of mathematicians, particularly teachers, who have an interest in pattern."
Inverse gas chromatography is a physical characterization analytical technique that is used in the analysis of the surfaces of solids. [1]Inverse gas chromatography or IGC is a highly sensitive and versatile gas phase technique developed over 40 years ago to study the surface and bulk properties of particulate and fibrous materials.
