Ultrafast Synthesis of Calcium Vanadate for Superior …
Recently, multivalent aqueous calcium-ion batteries (CIBs) have attracted considerable attention as a possible alternative to Li-ion batteries. However, traditional Ca-ion storage materials show either limited rate capabilities and poor cycle life or insufficient specific capacity. Here, we tackle these limitations by exploring materials having a large interlayer distance to achieve decent

The total calcium content was determined using ICP-AES (Jobin Yvon Horiba, JY2000 Ultrace, Longjumeau, France). The following pharmacokinetic parameters were estimated using Kinetica version 4.4 (Thermo Electron Corporation, Waltham, MA, USA): maximum concentration (C max ), time to maximum concentration (T max ), area under the plasma concentration-time curve (AUC), half-life (T …
Natural and anthropogenic drivers of calcium depletion …
This research breaks new ground by showing that, contrary to generally accepted theories of ecosystem development, calcium depletion has been occurring for millennia as a natural consequence of long-term ecosystem development. This natural process predisposed forest ecosystems in the region to detrimental responses to acid rain in the 20th century. We also show that nitrogen availability was

Glass for buildings - Designing Buildings Wiki
Glass for buildings - Designing Buildings Wiki - Share your construction industry knowledge. Glass is a material made from liquid sand. It is the name given to any amorphous (non-crystalline) solid that displays a glass transition near its melting point which is around 1,700°C (3,090°F). This means that materials transform from a hard and brittle state into a molten state, or vice versa
Solubility and Complexation Equilibriums
At 25 C and pH 7.00, K sp for calcium phosphate is 2.07 × 10 −33, indiing that the concentrations of Ca 2+ and PO 4 3− ions in solution that are in equilibrium with solid calcium phosphate are very low. The values of K sp for some common salts are listed in Table 17.1 "Solubility Products for Selected Ionic Substances at 25 C"; they show that the magnitude of K sp varies dramatically
