Polar and Dispersive Surface Tension Calculation
There are two methods for calculating the polar and dispersive surface tension components of a liquid: pendant drop & sessile drop method.
Contact Angle of Powders Comparision of Methods
The first step of dispersion and dissolution of a powder is wetting; therefore, understdanding the wettability behavior of powders is important in many applications such as inks, paints, food and pharmaceutical industry. The method to characterize powder wettability depends on the powder properties and application purposes. Sessile drop, Wilhelmy plate and liquid penetration (both column and thin film wicking) are common methods for determining the wettability of powders.
Solid Surface Free Energy
Solid surface free energy is one of the basic physical properties like density, melting point, refractive index, dielectric constant, modulus, etc. Measuring the solid surface free energy has applications in paints, coatings, and adhesives, semiconductors, printing, aerospace, mining, pharmaceutical and many more industries. To give an insight, high surface energy material is more reactive and stickier.
Automatic Contact Point Detection
Only few contact angle goniometers provide the back to front tilt of the camera. This feature enables the user to perfectly see the contact point. It also enables the software (Jikan Assistant) to automatically pick the contact points.
Scientific collaboration contract between Jikan and York university
negotiations were done between Jikan Nano-engineering company and some well-known professors and researchers of surface Nano-engineering science. These negotiations led to a contract between Jikan and Droplet Lab company founded by ِِDr Amirfazli, full professor of York university.
“R&D Fund of Industries and Mines” invests in Jikan
The VC (Venture Capital) contract between “Jikan Surface Nano-engineering Co.” and “R & D Fund Industries and Mines” signed in March 2018.
