As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb liquid”, according to researchers in Europe. This extends the study of correlated systems to electron ...

Mixtures of cyclohexyl acetate and cyclohexanol were used as a mixed solvent to study liquid-liquid equilibria (LLE) of the acetic acid-water-cyclohexanol-cyclohexyl acetate quaternary system. The ...

The most common method used for purifying biodiesel is washing with water. During the biodiesel washing process, two phases are formed, a water-rich phase and an ester-rich one. For this reason, ...

Using a Drude-based polarizable model, we investigate the liquid–vapor interface of hydrogen fluoride (HF) via molecular dynamics simulations. The interface displays a complex morphology with ...

The preferred source of formaldehyde is paraformaldehyde (Malz Jr. et al. 1977). AOH was synthesized according to reaction (6). The solvents used (methanol, ethanol, n-propanol and n-buthanol) were of ...

An add-drop filter based on linear waveguides coupled through a ring resonator in a two-dimensional phononic crystal is introduced and its operation in detecting methanol concentration in ethanol is ...
