Hace 5 días · Water mercury dynamics from rainfall to runoff were investigated. • The fate and transformation of runoff Hg can be accurately traced by Hg isotopes. • Terrestrial Hg is the major source of DHg in runoff water. • Photochemical and microbial reduction significantly affect DHg in runoff water.
Hace 3 días · This study investigates the escape of Mercury's sodium-group ions (Na +-group, including ions with m/q from 21 to 30 amu/e) and their dependence on true anomaly angle (TAA), that is, Mercury's orbital phase around the Sun, using measurements from MESSENGER.The measurements are categorized into solar wind, magnetosheath, and magnetosphere, and further divided into four TAA intervals.
Hace 4 días · From the non-linear Langmuir isotherm model, the adsorption capacity of the AC/DETA-TMC nanocomposite was determined as 317.3 and 263.6 mg g⁻¹ for inorganic mercury (Hg²⁺) and organic ...
Hace 16 horas · Physical properties. An old [10] pound coin (density ~7.6 g/cm 3) floats on mercury due to the combination of the buoyant force and surface tension. Mercury is a heavy, silvery-white metal that is liquid at room temperature. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity.
Hace 3 días · Fifty percent of the total mass of the atmosphere is located in the lower 5.6 km (3.5 mi; 18,000 ft) of the troposphere. Nearly all atmospheric water vapor or moisture is found in the troposphere, so it is the layer where most of Earth's weather takes place.
Hace 4 días · According to the long-term monitoring data from 2011 to 2020, the water temperature of Wuliangsuhai ranges from 0.1 to 29.8 °C, the pH value of the water ranges from 7.62 to 9.25, the water’s electrical conductivity ranges from 1.12 to 6.2 mS/cm, and the TDS ranges from 0.96 to 8.82 g/L [42,44].
Hace 4 días · Alkalinity is a water property that determines a water source’s ability to resist pH changes that would result in acidity. The most common alkalinity components are carbonate, hydroxide, and bicarbonate ions.
