The permittivities of pulverized samples of coal and limestone were measured over a range of bulk densities at 11.7 GHz and 20/spl deg/C. The measured values were used, along with particle densities, ...

Measuring density and volumetric shrinkage for adhesives is crucial to assess material quality and predict deformation in bonded parts.

We report on the formulation and characterization of hybrid hydrogels composed of gelatin and poly (ethylene glycol) diacrylate (PEGDA). Such hydrogels undergo sol–gel transitions either reversibly ...

Despite its importance, limited representations of the anthracite models have been developed. The first molecular representation of Chinese Jincheng anthracite with the incorporation of diverse ...

Then, each aliquot was tested by the helium gas pycnometer, yielding the value of the actual volume (Vreal) of the tested piece (aliquot). Three measurements were made for each aliquot of each sample.
