Activated carbon from paulownia wood Yields ofchemical activation stages
Yorgun, Sait; Yıldız, Derya; Şimşek, Yunus Emre (Taylor & Francis, 2016)Paulownia wood was used as a raw material in the preparation of activated carbon by chemical activation with phosphoric acid. The conversion of wood into activated carbon consists of sample preparation, impregnation, ... -
Combined Utilization KmnO4 Modified Starch Particles with Glycerol as De-Icer
Emre, Deniz; Şimşek, Yunus Emre; Değirmenci, Levent (Osman SAĞDIÇ, 2019)An alternative de-icer system consisted of biodegradable starch-modified KMnO4 (MS), and glycerol solution was proposed and tested with the present study. Experiments were performed with varying KMnO4 (10, 15, 25%) ... -
Determination of Optimal Conditions for Production of Highly Porous Carbon by Chemical Activation Method
Şimşek, Yunus Emre (Polish Academy of Sciences Institute of Physics, 2019)Activated carbon is a complex and crude form of graphite. Compared to graphite, activated carbon exhibits an unusual imperfect structure that is tremendously porous ranging from nanopore to milipore sizes. Its ... -
Effect of Activated Carbon Parameters on the Surface Properties of Wheat Straw Residue
Şimşek, Yunus Emre (IBCESS, 2016)Activated carbon has perfectly developed porosity, a large surface area (up to 3500 m2 g-1), and modifiable surface chemistry properties and exhibits a comparatively high degree of surface reactivity. Due to these reasons, ... -
Effect of Atmosphere and Temperature Treatment on Leoanarditefor Increasing Humic Acid Yield
Şimşek, Yunus Emre; Değirmenci, Levent (Springer, 2018)Humic acid is a complex molecule including carboxylic, phenolic, alcoholic, and carbonyl fractions in its structure. Addition of this complex structure in soil improves its fertility by increasing its porosity along ... -
Preparation and Characterization of High Purity Silica Obtained from Rice Husks
Şimşek, Yunus Emre (Polish Academy of Sciences Institute of Physics, 2017)Although SiO2 is produced mostly from mineral sources like quartz, it has recently been obtained from lignocellulosic natural resources, such as rice husk (hull). Several methods for extracting silica (SiO2) from rice husks ... -
Synthesis and Characterization of Hydroxyapatite Produced by Microwave Assisted Precipitation Technique
Şimşek, Yunus Emre; Avcı, Şenol (Polish Academy of Sciences Institute of Physics, 2019)In medical applications, the compliance and integration of bone with implant are a critical issue. Biocompatible metal substrates coated by suitable materials such as calcium phosphates, especially hydroxyapatite, ... -
ULTRASONIC MODIFICATION EFFECT OF ACTIVATED CARBONS ON THE REMOVAL OF ARSENIC IN WASTERWATERS
Aydın, Harun; Şimşek, Yunus Emre (İKSAD, 2020)Arsenic contamination is a global threat and challenge humankind faces due to its carcinogenic and toxic effects on humans and environment. Typical arsenic removal methods in wastewaters are Oxidation-precipitation, ...
