Negative Differential Capacitance from Composition-Dependent Stern Capacitance in a Binary Mixture
Yuki Uematsu
We develop a thermodynamic theory of electric double layers in binary liquid mixtures by allowing the Stern-layer capacitance to depend on the local solvent composition. This coupl…
Ion adsorption and zeta potential of hydrophobic interfaces
Yuki Uematsu
Hydrophobic interfaces have unique physicochemical properties and are used in various chemical products such as food, cosmetics, soap, and medicine and technologies such as pan coa…
Statistical-Mechanical Theory on the Probability Distribution Function for the Net Charge of an Electrolyte Droplet
Yuki Uematsu, Keiju Suda
Droplets of electrolyte solutions in an insulating medium are ubiquitous in nature. The net charges of these droplets are normally nonzero, and they fluctuate. However, a theory on…
Diffuse-Layer Capacitance at the Potential of Zero Charge in Binary Mixtures
Yuki Uematsu
The capacitance of the electric double layer has potential applications in supercapacitors, and theoretical investigations of the double-layer capacitance in binary mixtures are im…
Ostwald Ripening of Buoyancy-Driven Microbubbles
Yuki Uematsu
Microbubble solutions have a wide range of industrial applications, including heat transfer, agriculture, and water treatment. Therefore, understanding and controlling the size var…
