Keeping this idea in mind, we reported a chemistry of H2O and alkyne in this work. This reaction could happen under air at room temperature in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) as an organic catalyst. The resultant nonaromatic products are verified as clusteroluminogens...

The water chemistry data of groundwater and pore-water samples were respectively placed on the Gibbs plot according to depth and runoff, as shown in Fig. 5. The samples of groundwater and pore water were distributed in the zone between rock weathering and evaporation-crystallization, indicating ...
2e, d). These molecules are used as a cryoprotectant21,42,43,44, or as an additive during crystallization10,45. This implies that small molecules like cryoprotectants can pass through the cavity of the O1 channel. The presence of these molecules in the channel leads to changes in the water...
The hydration state of a hydrate depends on the water activity, aw in the crystallization medium. Selection of an appropriate ratio of water to cosolvent in the crystallization medium of a hydrate is critical and is often semi-empirical. This study attempts to elucidate this selection process by...
increase crystallization and formation of a smaller ZnO nanoparticle. Under high concentration of the hydroxyl ions in a solution, intermediate products such as zinc hydroxide (Zn(OH)2) (see Eq.1) and salt-containing tetrahydroxozincate ion ([Zn(OH)4]2−) (see Eq.2) are formed (Rafaie...
stream water will be under the dominance of processes associated with solution of the weathering soil mantle (rock dominance), the concentrations of ions in precipitation (precipitation dominance) or the balance between evaporation and crystallization within the basin (evaporation - crystallization ...
Solar energy is the most sustainable alternative to fossil fuels. The production of solar thermochemical fuels from water/carbon dioxide not only overcomes
Importance of heat storage materials has recently been increasing. Although various types of heat storage materials have been reported to date, there are few well-balanced energy storage materials in terms of long lifetime, reversibility, energy density,
Etching (often considered as decomposition) is one of the key considerations in the synthesis, storage, and application of metal nanoparticles. However, the underlying chemistry of their etching process still remains elusive. Here, we use real-time elect
