Quantitative Elastohydrodynamic Film-Forming for an Oil/ Refrigerant System
منشور في 2017"…It is demonstrated that primary measurements of the properties of the oil/refrigerant system can be employed to accurately predict film thickness in concentrated contacts. An unusual response to lubricant inlet temperature is revealed, wherein the film thickness may increase with temperature as a result of decreasing refrigerant solubility in oil when the inlet pressure is high. …"

Optoelectronic properties of highly porous silver oxide thin film
منشور في 2021"…The obtained results indicate the formation of mixed mesoporous Ag<sub>2</sub>O and AgO NW thin films. The Ag<sub>2</sub>O phase of silver oxide appears after 300 s of oxidation under the same conditions, while the optical transparency of the thin film decreases as plasma etching time increases. …"

Bulk passivation of perovskite films utilizing halide anion ionic liquids
منشور في 2023"…The average lifetimes obtained within one day of preparations were 79 ns, 73 ns and 275 ns for pristine perovskite, IL-I passivated perovskite and IL-Cl passivated perovskite films, respectively. These values show that the presence of the IL with chloride anion greatly improves the average lifetime of the charge carrier by around 250%, while IL with iodide anion decreased the lifetime by 32% as compared with the pristine perovskite sample. …"
