Thermal Decomposition of Synthetic Argentojarosite - Implications for Silver Production in Medieval Times [PDF]
, 2005 The thermal decomposition of argentojarosite has been studied by thermogravimetric, spectroscopic and infrared emission techniques. Dehydroxylation occurs in three stages at 228, 383, 463 degrees Celsius with the loss of 2, 3 and 1 hydroxyl units.

Identification of the dimethylamine-trimethylamine complex in the gas phase [PDF]
, 2012 We have identified the dimethylamine-trimethylamine complex (DMA-TMA) at room temperature in the gas phase. The Fourier transform infrared (FTIR) spectrum of DMA-TMA in the NH-stretching fundamental region was obtained by spectral subtraction of spectra ...

Temperatures of Positively and Negatively Stretched Flames.
JSME International Journal Series B, 2003 Both tubular flame temperature and Bunsen flame temperature have been measured for lean methane, hydrogen and propane/air mixtures. These temperatures have been compared with the adiabatic flame temperature, which is the typical temperature with no stretch.

Flexural phonons in free-standing graphene [PDF]
, 2007 Rotation and reflection symmetries impose that out-of-plane (flexural) phonons of free-standing graphene membranes have a quadratic dispersion at long wavelength and can be excited by charge carriers in pairs only.

Influences of stretch and curvature on the temperature of stretched cylindrical diffusion flames
Journal of Thermal Science and Technology, 2016 The structure of a counterflow-type cylindrical diffusion flame was studied experimentally to determine the effect of stretch and curvature. The cylindrical flame used in this study had a concave curvature with respect to the fuel stream. The fuels used were propane and methane, diluted with nitrogen, argon or helium.

On the correlation between fragility and stretching in glassforming liquids
, 2006 We study the pressure and temperature dependences of the dielectric relaxation of two molecular glassforming liquids, dibutyl phtalate and m-toluidine. We focus on two characteristics of the slowing down of relaxation, the fragility associated with the ...
