This force is related to the contact angle by the following equation: cos θ = F − F b I σ , {\displaystyle \cos \theta ={\frac {F-F_{\text{b}}}{I\sigma }},} where F is the total force measured by the force meter, F b is the force of buoyancy due to the solid sample displacing the liquid, I is the wetted length, and σ is the known ...
Secondary forces, such as van der Waals or hydrogen bonding, cause monomers to cluster into a non-covalently bonded network that retains organic solvent, and as the network grows, it exhibits gel-like physical properties. [2] Both gelation mechanisms lead to gels characterized as organogels. Example of organogelator molecules.
Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.
Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials.It is most useful for studying the viscoelastic behavior of polymers.A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus.
A frequency-selective surface (FSS) is any thin, repetitive surface (such as the screen on a microwave oven) designed to reflect, transmit or absorb electromagnetic fields based on the frequency of the field.
