“…Both these facts allow us to conclude that FAB mass spectra of water-ice containing a small amount of sulfuric acid reflect thermodynamic properties of the solutions. 31 In addition, preliminary studies of FAB mass spectra of water solutions containing ferrous or ferric ions were conducted.

The application of fast-atom bombardment (FAB) mass spectrometry to solving the problems of heterogeneous atmospheric chemistry is briefly reviewed. The method is useful in studying the state of surfaces and molecules adsorbed thereon and looks appropriate in investigations of the dynamics and mechanisms of chemical reactions occurring both on a surface and in a volume of moving particulate matter suspended in a gas. It was shown that composition of atmospheric aerosols and components dissolved in atmospheric water (clouds, fogs, mists etc.) can be determined by the FAB technique. The given method, as was found in our investigations, allows the discrimination of ferrous and ferric ions. Detection limits for concentrations of H2SO4 and Fe(II / III) ions as essential components of atmospheric water determined in model experiments are established at the level of 10−6 M.

A Logical (Discrete) Formulation for the Storage and Recall of Environmental Signals in Plants

When subjected to an appropriate asymmetric stimulus, seedlings of Bidens pilosa L. "store" a symmetry-breaking instruction that will finally take effect (in the form of a differential growth of the cotyledonary buds) only if the plants are in a state in which they can "recall" this information. The ability of the plants to recall the stored symmetry-breaking instruction may be switched "on" or "off" by the application of a variety of stimuli. Although its detailed phenomenology is rather complicated, the overall behaviour of the plant storage/recall system can be modelled by use of an asynchronous, logical (discrete) description involving positive and negative feedback circuits, which are required for the existence of multi-stationarity and stability, respectively. The state tables, as used in this formalism, give a concise and easy-to-handle description of the evolution of the system and make it particularly easy to determine its stable states. This modelling approach may be extended to the formulation of many other experimental systems.

“…[4][5][6] Recently, several studies using FAB-MS, have been carried out to examine the solution chemistry [7] and environmental problems. [8] Here, we applied the measurement by FAB-MS to the identification of the chemical species of silica in the solution as it were [9][10][11][12] and to their chemical characterization. [13][14][15][16] The final purpose of our study is to measure directly the silicate species in natural water samples such as seawater and hot spring water, which contains a low concentration of silica, since the detection limit for determination of species of silica by FAB-MS is only 0.3 mmol dm À3 (mM).…”

The types of chemical species of silicate complex ion exchanged with sodium ions (silicate-Na þ complex) with increasing concentration of sodium chloride (NaCl) and their numbers of chemical species of silicate-Na þ complexes formed were examined. Silicate-Na þ complexes in several concentrations of NaCl were identified by fast atom bombardment mass spectrometry (FAB-MS). The basic structures of silicate species are not complexes with Na þ , such as the dimer, trimer, cyclic tetramer, linear tetramer, cyclic pentamer, linear pentamer, cyclic hexamer and linear hexamer, were identified. When the peak intensity ratios of silicate-Na þ complexes were plotted against the concentration of NaCl, the changes with increasing concentration of NaCl were mainly classified into two patterns. One is the linear silicate-Na þ complex pattern (dimer-Na þ complex, trimer-Na þ complex and linear tetramer-Na þ complex), and the other is the cyclic silicate-Na þ complex pattern (cyclic tetramer-Na þ complex and cyclic pentamer-Na þ complex). In the linear silicate-Na þ complex pattern, the peak intensity ratios of the linear silicate-Na þ for the basic structures vary largely between 0.001 and 0.1 mol dm À3 (M) NaCl, and they become constant at above 1 M NaCl. In the cyclic silicate-Na þ complex pattern, the peak intensity ratios of the basic structures of cyclic silicate-Na þ change slightly between 0.001 and 0.1 M NaCl and change considerably above 1 M NaCl. The basic structure of cyclic silicate has a stable structure and hydrophobic part. By substituting Na þ , the hydrophobicity of the cyclic silicate complex increases. The linear silicate complex is not as stable as the cyclic silicate complex and it possesses a higher degree of hydration than the cyclic silicate. The hydrophobicity of the linear silicate also increases by the substitution of silanol groups by Na þ . These changes of the hydrophobicity of the linear silicate due to the substitution of Na þ are larger than those for the cyclic silicate. The dissolution system of the silicate species in NaCl solution should be elucidated by considering the relationship between the stabilities of the basic structure and Na þ -containing silicate complexes, and their hydration effect.
