    Synergistic effects of benzalacetone and benzophenone on the electrocrystallization of tin from acid stannous sulphate solutions (1994)

    Notes: Abstract The synergistic effects of two kinds of aromatic ketones (benzalacetone (BA), benzophenone(BP)) and N,N-bis(polyoxyethylene)octadecylamines (POOA) on the surface morphology and the crystal orientation of electrodeposited tin from acid stannous sulphate solutions have been studied by electrochemical methods, scanning electron microscopy and X-ray diffractometry. BA itself had no effect on the reduction of tin (II) ions, but the reduction product of BA had a strong inhibitory effect on the reduction of tin (II) ions. However, the inhibitory effect of BP was stronger than that of the reduction product of BP. POOA induced a uniform deposition of tin over the whole surface, but the crystal grain size and the surface roughness of electrodeposited tin were relatively large. On the other hand, fine-grained and smooth electrodeposited tin, which had a preferred orientation with the (10 0) plane parallel to the surface, were obtained from acid stannous sulphate solutions containing POOA, BA and BP due to the synergistic effects of the three kinds of adsorbed species. It was found that BA has a levelling action and BP has a grain refinement action.

    Surface morphology and crystal orientation of electrodeposited tin from acid stannous sulphate solutions containing various additives (1994)

    Notes: Abstract The changes in surface morphology and crystal orientation of electrodeposited tin from acid stannous sulphate solutions containing 1 mm N,N-bis(tetraoxyethylene)octadecylamine (TOGA) and various concentration (0.2–2 mm) of benzalacetone (BA) have been studied as functions of electrolysis time or BA concentration by electrochemical methods, scanning electron microscopy and X-ray diffractometry. The inhibitory effect on the reduction of the tin (II) ion became stronger with increasing concentration of BA. In the presence of both TOOA and BA, when electrolyses were carried out at the more negative potentials than the reduction potential of BA, the reduction product of BA induced reticular crystals (network structure) of tin over the whole surface. This structure appeared in the early stage of electrolysis and exhibited an intense (200) diffraction peak. On the other hand, the crystal grain size and the surface roughness of electrodeposited tin became smaller with increasing concentration of BA from 0.2 to 2 mm. Further, fine-grained and smooth electrodeposits of tin were obtained from acid stannous sulphate solutions containing TOOA and high concentration of BA due to the synergistic effect of these adsorbed species.

    Automatic titration of reducing gases in inert gases using an oxygen pump-gauge (1990)

    Notes: Abstract A computer-aided gas analyzing system with a zirconia oxygen pump-gauge was developed and used to measure a small amount of reducing gas in a flowing inert gas. The flowing Ar containing CO or CH4 was automatically titrated with oxygen by scanning the current of the oxygen pump; on-line titration data were analyzed by correcting for the response delay of the EMF sensor to the pump current. This scan method is very advantageous for a precise and rapid determination of the total oxygen demand (TOD) of the flowing gas.

    Effects of saccharin and aliphatic alcohols on the electrocrystallization of nickel (1994)

    Notes: Abstract The effects of saccharin and three kinds of aliphatic alcohols (n-propyl alcohol, allyl alcohol, propargyl alcohol) on the surface morphology and crystal orientation of electrodeposited nickel from a Watts bath (1 M NiSO4 + 0.21 M NiCl2 + 0.51 M H3 BO3 have been studied by means of electrochemical methods, scanning electron microscopy, energy-dispersive X-ray analysis and measurements of X-ray diffraction patterns. Saccharin and three kinds of aliphatic alcohols were adsorbed on the electrode and inhibited the reduction of nickel ion. The inhibitory effect on the reduction of nickel ion increased in the order n-propyl alcohol, allyl alcohol and propargyl alcohol. Large granular electrodeposits were obtained from the Watts bath in the absence of organic additives. When saccharin was added, fine-grained crystals were observed and the surface roughness was relatively small. When aliphatic alcohols were added, the size of surface morphological features became smaller in the order n-propyl alcohol, allyl alcohol and propargyl alcohol. Fine-grained, compact and smooth nickel electrodeposits, which had a preferred orientation with a (111) plane parallel to the surface, were obtained from the Watts bath containing both saccharin and propargyl alcohol.

    A novel preparation of gold films by electrodeposition at the interface between a Na(AuCl4)–CuSO4 aqueous phase and an immiscible hexyl acetate organic phase (1997)

    Notes: Abstract Electrolysis at the interface between a Na(AuCl4)–CuSO4 aqueous phase and an immiscible hexyl acetate phase resulted in continuous growth of gold films along the interface. To maintain filmy growth of gold, it was effective to stimulate displacement of predeposited copper with gold by applying a rectangular or triangular potential in a given range. Two types of electrodes were applied: from a point electrode the film grew concentrically like a blooming flower, and from a line electrode the film grew unidirectionally toward the counter electrode as a spreading wave. A long time electrolysis could be performed by circulating and filtering the aqueous solution. The film contained no trace of copper and was very thin (〈1μm).

    Notes: Abstract Sinusoidal currents were applied to the pumps of pump-gauge devices constructed from zirconia, enclosing a sealed volume of less than 1 mm3. Values for the gauge e.m.f. were monitored versus time and compared with theoretical equations derived assuming ideal behaviour. Under a low signal condition, where the amplitude of the gauge e.m.f. was ≤2.3 mV (at 800°C), the theory predicted that the e.m.f. should also be sinusoidal but with a π/2 phase shift relative to the current. Under a high signal condition, on the other hand, where the amplitude of the gauge e.m.f. was〉10 mV, substantial distortion of the e.m.f. variation from a pure sinusoid was anticipated. Observed behaviour was in general closely in accordance with these predictions, although some deviation was apparent at low internal pressures (〈0.01 atm).

    Notes: Abstract The synergistic effects of adsorbed species (polyoxyethylenealkylamine (POAA), diphenylamine-crotonaldehyde reaction product (RP) and benzalacetone (BA)) on the surface morphology and crystal orientation of electrodeposited tin from acid stannous sulfate solutions have been studied by means of various electrochemical methods, scanning electron microscopic observation and measurements of X-ray diffraction patterns. Needle-like or columnar electrodeposits of tin were obtained from acid stannous sulfate solution in the absence of adsorbed species. On the other hand, fine-grained, smooth and compact electrodeposits of tin, which had a preferred orientation with the (200) plane parallel to the surface, were obtained from acid stannous sulfate solutions containing POAA, RP and BA due to the synergistic effect of the three kinds of adsorbed species. It was found that POAA acts to produce a uniform tin deposition over the whole surface, RP acts as a grain refiner and BA has a leveling action.

    Notes: Abstract A topoisomerase II inhibitor, novobiocin, and a deacetylase inhibitor, butyrate, synergistically transformed human liver cells into fibroblast-like cells. This morphological change was associated with an increased production of procollagen type III peptide and a simultaneous assembly of actin, tubulin, vimentin and cytokeratin. Novobiocin and butyrate had no marked effect on the phosphorylation state of cytokeratin proteins, but synergistically enhanced [3H]acetate uptake. From these results, it can be speculated that protein acetylation plays an important role in inducing the assembly of cytoskeletal proteins and the morphological transformation of human liver cells.
