In certain circumstances, the presence of metalionsis undesirable, as, for example, inwater, in whichcalcium(Ca2+) andmagnesium(Mg2+) ions cause hardness. In such cases the undesirable effects of the metal ions frequently can be eliminated by “sequestering” the ions as harmless complexes throu...
PURPOSE:To reduce running cost and to miniaturize equipment by a method wherein the water subjected to gas-liquid co-current aeration flooding from the lower part of the first packed tower is subjected to water sprinkling countercurrent aeration in the upper part of the second packed tower to be...
in which oxygen (O) is covalently bonded to other nonmetals such as sulfur (S) or nitrogen (N). When ionic oxides are dissolved inwater, the O2−ions react with water molecules to formhydroxideions (OH−), and a basic solution results. Molecular oxides react with water to produce ...
Active Water in Protein−Protein Communication within the Membrane: The Case of SRII−HtrII Signal Relay We detect internal water molecules in a membrane-embedded receptor−transducer complex and demonstrate water structure changes during formation of the si... VB Bergo,EN Spudich,JL Spudich,...
The invention relates to a solid formulation containing a liquid composition containing a water-insoluble solid phytosanitary product. The invention especially relates to a solid formulation enabling the formation of nanoparticles of the phytosanitary product during a dispersion in water.Jean-Pierre Hecaen...
