    Study of Dehydration Behavior of Silica Xerogel and Aerogel by Diffuse Reflectance Fourier Transform Spectroscopy
    (Apple Academic Press, 2024) Yetgin, S.; Balkose, D.
    The pore size, surface area, and density of silica gel were controlled by drying silica alcogel in ambient conditions and using supercritical ethanol extraction to obtain silica xerogel and silica aerogel, respectively, in the present study. The samples were characterized by N2 gas adsorption at −196°C, scanning electron microscopy and Fourier transform infrared (FTIR) spectroscopy and diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy. The effect of time on surface characteristics of silica aerogel up to three-month storage time was investigated by N2 gas adsorption. The functional groups of the xerogel and silica aerogel and a commercial mesoporous silica gel were examined by FTIR transmission spectroscopy. The effects of pressure, relative humidity, and temperature on hydration–dehydration behavior of silica aerogel and silica xerogel were investigated using a temperature and pressure-controlled chamber in diffused reflectance cell of FTIR spectrophotometer. It was observed that free water was eliminated from the samples under vacuum at ambient temperature. Hydrogen-bonded OH groups and isolated OH groups were eliminated partially by heating the samples up to 500°C. The samples heated up to 500°C and cooled to ambient conditions had still had the capability of adsorbing free water. © 2024 Apple Academic Press, Inc.

    Physics and Mechanics of New Materials: Synthesis, Processing, and Emerging Applications
    (Apple Academic Press, 2024) Balkose, D.; Ribeiro, A.C.F.; Kalarikkal, N.; Abraham, A.R.; Haghi, A.K.
    This new volume covers new advances in materials science and engineering technology, focusing on practical rather than theoretical aspects that are useful for the design, fabrication, testing, and industrial application of advanced materials and structures. The first section of this book delivers a comprehensive overview of modern ferrites with special attention to their structure, types, and properties. It presents a comprehensive survey on ferrite materials with discussions of selected applications of modern ferrite materials in emerging technologies. In the second section, the impact of technological change upon the application of selected materials and energy resources are presented in detail. This includes discussions on 2D nanomaterials, bismuth ferrite, and barium titanate and how these can be put to practical use. In the last section of this volume, case studies in thermophysics and applied mechanics for engineering technology are presented that provide an examination of the various physical, chemical, and material properties of a range of modern materials. This research-oriented book, Physics and Mechanics of New Materials: Synthesis, Processing, and Emerging Applications, is an essential reference source intended for scientific researchers, faculty, and postgraduate and senior students who specialize in the field of materials science and applied mechanics of materials. © 2025 by Apple Academic Press, Inc.
