Group 12 metal zwitterionic thiolate compounds: preparation and structural characterization.
Reactions of TabHPF(6) (Tab = 4-(trimethylammonio)benzenethiolate) with three equiv. of M(OAc)(2)·2H(2)O (M = Zn, Cd) gave rise to two tetranuclear adamantane-like compounds, [M(4)(μ-Tab)(6)(Tab)(4)](PF(6))(8)·S (·S: M = Zn, S = DMF·4H(2)O; ·S: M = Cd, S = DMF·5H(2)O). The similar reactions of MCl(2) (M = Zn, Cd, Hg) with four equiv. of TabHPF(6) in the presence of Et(3)N afforded three mononuc...
متن کاملSpectroscopic study of tetradecyltrimethylammonium bromide Pt-C14TAB nanoparticles: structure and stability.
The vibrational spectra of platinum nanoparticles (12 nm) capped with tetradecyltrimethylammonium bromide, C(14)TAB, were investigated by Fourier transform infrared (FTIR) spectroscopy. We have shown that the thermal decay of Pt-C(14)TAB nanoparticles in N(2), H(2), and O(2) atmospheres leads to the release of the hydrocarbon chain of the surfactant and the formation of a strongly bonded layer ...
متن کاملThe Infant Version of the Laboratory Temperament Assessment Battery (Lab-TAB): Measurement Properties and Implications for Concepts of Temperament
We describe large-sample research using the Infant Laboratory Temperament Assessment Battery (Lab-TAB; Goldsmith and Rothbart, 1996) in 1,076 infants at 6 and 12 months of age. The Lab-TAB was designed to assess temperament dimensions through a series of episodes that mimic everyday situations. Our goal is to provide guidelines for scoring Lab-TAB episodes to derive temperament composites. We a...
متن کاملDeriving childhood temperament measures from emotion-eliciting behavioral episodes: scale construction and initial validation.
The authors describe the development and initial validation of a home-based version of the Laboratory Temperament Assessment Battery (Lab-TAB), which was designed to assess childhood temperament with a comprehensive series of emotion-eliciting behavioral episodes. This article provides researchers with general guidelines for assessing specific behaviors using the Lab-TAB and for forming behavio...
متن کاملEffect of the chain-length compatibility of surfactants and mechanical properties of mixed micelles on surfaces.
Force/distance curves for silicon nitride tip/flat silica or alumina coated by a layer of mixed micelles of cationic/anionic surfactant are measured by using AFM. Mixtures of SDS/C(n)TAB (with molecular ratios of 3:1 and 20:1) and C(n)TAB/SDS (with molecular ratio of 85:15) were used for alumina and silica substrates, respectively. The number of carbon atoms per C(n)TAB molecule, n, was in the ...
