Synthesis, characterization and thermal decomposition of bismuth(III) ternary complexes of phthalate

Two new complexes of bismuth nitrate with phthalic acid (H2phth) were synthesized by liquid state reaction. The complexes were characterized by chemical and elemental analyses, Fourier transformed infrared spectra, X-ray powder diffraction and thermgravimetry analysis. Their compositions are Bi(phth)(NO3)·4H2O and Bi(phth)(L-cys)0.5·H2O (L-H2cys = L-cystine), respectively. The crystal structure...

New trends in bismuth-catalyzed synthetic transformations.

This review covers uses of bismuth catalysts since 2005 with a special emphasis on the emerging applications of such catalysts. Low toxicity, low catalytic loading, synergistic effects with other catalysts, and some hydrocompatibility properties confer to bismuth salts major advantages. The expanding activity in the field clearly highlights the growing potential of bismuth catalysts. The articl...

Mode-Wise Thermal Conductivity of Bismuth Telluride

Thermal properties and transport control are important for many applications, for example, low thermal conductivity is desirable for thermoelectrics. Knowledge of modewise phonon properties is crucial to identify dominant phonon modes for thermal transport and to design effective phonon barriers for thermal transport control. In this paper, we adopt time-domain (TD) and frequency-domain (FD) no...

Thermal conductivity suppression in bismuth nanowires

The thermal conductivity of individual bismuth nanowires was characterized using a suspended microdevice and correlated with the crystal structure and growth direction obtained by transmission electron microscopy on the same nanowires. Compared to bulk bismuth in the same crystal direction perpendicular to the trigonal axis, the thermal conductivity of a single-crystal bismuth nanowire of 232 n...
