Solar-driven water purification is considered as an effective and sustainable technology for treatment using green solar energy. One major goal practical applications to improve the evaporation performance by design of novel photothermal materials, with optimized heat localization transport pathways achieve reduced energy consumption vaporization. Recently, some emerging materials like polymers...

[1] The most energetic planetary collisions attain shock pressures that result in abundant melting and vaporization. Accurate predictions of the extent of melting and vaporization require knowledge of vast regions of the phase diagrams of the constituent materials. To reach the liquid-vapor phase boundary of silica, we conducted uniaxial shock-and-release experiments, where quartz was shocked t...

PURPOSE To assess the prevalence and extent of irrigation fluid absorption during thulium laser vaporization of the prostate. MATERIAL AND METHODS Fifty-four patients undergoing thulium laser vaporization of the prostate were prospectively included into the trial at a tertiary referral center. Isotonic saline containing 1% ethanol was used for intraoperative irrigation. Absorption of irrigati...

The fusion enthalpies of the series butanedioic acid through to tetradecanedioic acid and hexadecanedioic acids have been measured by DSC. In addition to fusion, a number of solid–solid phase transitions have also been detected in these diacids. The vaporization enthalpies of these compounds have been measured by correlation gas chromatography using the vaporization enthalpies of butanedioic, h...
