Book Part Applications of Light-Emitting Diodes in Liquid Foods(Apple Academic Press, 2025) Cankal, Y.S.; Ünlütürk, S.Recently, there has been increased interest in investigating alternative nonthermal processes to maintain the quality of liquid food products while preserving their nutritional value. Ultraviolet (UV) irradiation technology is one such method and has been widely explored for liquid food products. Low or medium-pressure mercury vapor lamps are used in this technology. Since these lamps contain mercury known to have toxic effects on the human body and the environment [18], the use of light-emitting diodes (LEDs) has become prominent as an ultraviolet light source. LEDs are created using non-toxic semiconductor material, which allows emitting in different wavelengths. Recently, Light Emitting Diode (LED) technology has been emerging as a non-thermal and non-chemical treatment for surface disinfection and preservation of solid and liquid food materials. This chapter emphasizes the application and effectiveness of LEDs of different wavelengths in liquid food processing and storage. © 2025 by Apple Academic Press, Inc.Book Part Light-Emitting Diodes: Mechanism of Inactivation of Microorganisms and Effects on Different Microorganisms(Apple Academic Press, 2025) Cankal, Y.S.; Ünlütürk, S.UV lights are widely used for surface disinfection, sterilization of water, and various liquid foods. The usage of light-emitting diodes (LEDs) has become prominent as a light source for sterilization and decontamination of materials. LEDs have been widely investigated for water treatment. However, there are limited studies on the use of LEDs for food materials due to their low light transmittance capabilities. To develop the most effective treatment for sterilization and decontamination purposes in food processing, it is necessary to know what the different microbial inactivation mechanisms of LEDs are and what their limitations are for use. This chapter includes discussions on the microbial inactivation efficiency of light-emitting diodes (LEDs) of different wavelengths; and the inactivation mechanisms of various microorganisms (such as bacteria, viruses, molds, algae, and yeast). © 2025 by Apple Academic Press, Inc.Book Part Citation - Scopus: 1Study 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.Book Part Investigating the Adhesion Problem of a Double-Sided Tape and Car Bumper Packing Materials(Apple Academic Press, 2024) Balköse, D.; Cihanoğlu, G.; Kirköse, S.; Karabiyik, M.; Olcay, A.N.Pressure-sensitive adhesives (PSAs) are viscoelastic materials with permanent stickiness, and can adhere strongly to solid surfaces upon application of slight contact pressure under a relatively short contact time. The adhesion problem of double-sided adhesive to packing films of car bumpers was investigated by analyzing the flexible adhesive layer and two alternative packing films. The films were blue in color and one of them was opaque and the other one was transparent. Scanning electron microscopy (SEM), Fourier transfer infrared (FTIR) spectroscopy were used to characterize the samples. Water contact angle and roughness of surfaces were also determined. It was shown that the film with high surface roughness and high water contact angle adhered better to the flexible adhesive layer. © 2025 by Apple Academic Press, Inc.Book Citation - Scopus: 1Physics 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.

Although, the alkali salts of the fatty acids such as sodium and potassium are water soluble, metal soap is water insoluble but more soluble in nonpolar organic solvents [1]. Some commercially important metal soap include those of Alluminum, barium, cadmium, calcium, cobalt, copper, iron, lead, lithium, magnesium, manganese, potassium, nickel, zinc, and zirconium. Significant application areas for metal soaps include lubricants and heat stabilizers in plastics as well as driers in paint, varnishes, and printing inks. Other uses are as processing aids in rubber, fuel and lubricant additives, catalysts, gel thickeners, emulsifiers, water repellents, and fungicides [2]. © 2013 by Apple Academic Press, Inc.Book Part Calcium Soap Lubricants(Apple Academic Press, 2015) İzer, Alaz; Kahyaoğlu, Tuğçe Nefise; Balköse, DevrimThe reparation and characterization of calcium stearate (CaSt2) and a lubricant by using calcium stearate were aimed at in this study. Calcium stearate powder was prepared from sodium stearate and calcium chloride by precipitation from aqueous solutions. CaSt2 and the Light Neutral Base oil were mixed together to obtain lubricating oil. It was found that CaSt2 had a melting temperature of 142.8 °C and in base oil it had a lower melting point, above 128 °C. It was dispersed as lamellar micelles as the optical micrographs had shown. From rate of settling the size of dispersed particles were found to be 1.88 ?m and 0.11 ?m for lubricants having 1% and 2% CaSt2, respectively. The friction coefficient and wear scar diameter of base oil 0.099 and 1402 nm were reduced to 0.0730 and 627.61 nm respectively for the lubricant having 1% CaSt2. Lower wear scar diameter (540 nm) was obtained for lubricant with 2% CaSt2. CaSt2 improved the lubricating property of the base oil but did not improve its oxidative and thermal stability. © 2015 by Apple Academic Press, Inc.Book Citation - Scopus: 5Aluminium-Coated Polymer Films as Infrared Light Shields for Food Packing(Apple Academic Press, 2014) Hamrang, Abbas; Balköse, Devrim; Zaikov, Gennadij Efremovich; Haghi, A.
