A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams
Advanced Engineering Materials, EarlyView.The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.

On Static Dielectric Response of Microcomposites of the Type: Ferroelastics - Dielectrics [PDF]
arXiv, 2005 We describe the static dielectric response of ferroelastic-dielectric microcomposites. Its dependence on temperature, pressure and concentration is considered for smaller concentrations and for temperatures above the critical temperature. We have found a qualitative agreement with existing experimental data for $Al_{2}(WO_{4})_{3}$.

On the Static Dielectric Permittivity for Coulomb System in the Long Wavelength Limit [PDF]
, 2009 On the basis of the exact relations the general formula for the static dielectric permittivity for Coulomb system is found in the region of small wave vectors. The obtained formula describes the dielectric function of the Coulomb system in both limits: in the "metallic" state and in the "dielectric" one.

Dielectric crystal in the Planck blackbody [PDF]
arXiv, 2015 The dielectric crystal with the index of refraction n is inserted in the Planck blackbody. The spectral formula for photons in such dielectric medium is derived with the equation for the temperature of internal photons. The derived equation is solved for the constant index of refraction.

True Dielectric and Ideal Conductor in Theory of the Dielectric Function for Coulomb System [PDF]
, 2009 On the basis of the exact relations the general formula for the static dielectric permittivity e(q,0) for Coulomb system is found in the region of small wave vectors q. The obtained formuladescribes the dielectric function e(q,0) of the Coulomb system in both states in the "metallic" state and in the "dielectric" one.

Advanced Engineering Materials, EarlyView.Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived
