Cotton stalks were subjected to alkaline pretreatment for the co-production of glucose and hemicellulose based films with a multi-product approach. Three pretreatment temperatures (25, 60 and 90 degrees C) were evaluated for their effects both on the glucose yield and on the properties of hemicellulose based films. Compared to untreated cotton stalks, the glucose yields were enhanced 3.9, 4.1 and 4.2 times for pretreatments conducted at 25, 60 and 90 degrees C, respectively. The pretreatment temperature of 90 degrees C was detrimental in terms of film formation. Tensile energy to break values of the films obtained after pretreatments conducted at 25, 60 and 90 degrees C were 1.1, 0.8, and 0.4 MJ/m(3), respectively. The hemicellulosic part of the process, which considers the production of hemicellulose based films, should govern the pretreatment temperature since it was more responsive to the changes in the pretreatment temperature compared to the cellulosic part that accounts for glucose production.

Efficient Acetylation of Xylans by Exploiting the Potassium Acetate Formed During the Alkaline Extraction
AKKUS, Merve; Özkan, Necati; BAKIR, Ufuk (2018-08-01)
Isolation of hemicelluloses through alkaline extraction results in formation of salts, which usually necessitates additional salt removal steps. In this study, acetylation of xylans was studied without the removal of potassium acetate (KAc), a commonly produced salt during the alkaline extraction, to find a facile method to alter the hydrophilic characteristics of hemicelluloses. The acetylation reaction was carried out solely with acetic anhydride without any catalysts or solvents added. The weight gain an...
Development of pea flour based active films produced through different homogenization methods and their effects on lipid oxidation
Yıldız, Eda; Şümnü, Servet Gülüm; Şahin, Serpil (Elsevier BV, 2021-02-01)
The objective of this study was to investigate the effects of gallic acid incorporation and homogenization method (high-speed homogenization and ultrasonication) on the physicochemical characteristics of pea flour based active films and the activity of the films against lipid oxidation. The water vapor permeability results of the active films increased by approximately 16% with the addition of gallic acid. Furthermore, active films had higher elongation and flexibility due to the plasticizing effect of gall...
Investigation of the performance of colloidal LiFePO4 particles in suspension flow battery
Yıldız, Bayram; Aşkar, Yasemin; Coşkun, Elif; Maviş, Bora; Çınar, Simge (2021-06-12)
In this study, colloidal LiFePO4 particles were synthesized through solvothermal route. Effect of solvothermal method parameters on formation of colloidal LiFePO4 was investigated. Post-processing treatments were found effective to obtain non-aggregated colloidal particles. The rheological behavior of aqueous suspensions including electroactive material was examined in terms of salt, electroactive material concentration and carbon content. A three-electrode systems was used to analyze electrochemical perfor...
Measurement of transport properties of poly(methylmethacrylate-co-methacrylic acid) ion-containing membranes
Şanli, Oya; Aras, Leyla (Wiley, 1990)
Several membranes prepared from poly(methylmethacrylate‐co‐methacrylic acid) and its Li+ and Zn2+ ionomers were tested for NaCl, creatinine and urea permeability. The permeabilities of the membranes were explained on the basis of pore contents determined from their scanning electron microscope micrographs. All the membranes showed higher permeabilities during the first 2 hours of experimentation. Introduction of Zn2+ ions into the copolymer as crosslinking agent did not have much effect on the membrane prop...
Comparison of antioxidant enzyme activities and DNA damage in chickpea (Cicer arietinum L.) genotypes exposed to vanadium
Imtiaz, Muhammad; Mushtaq, Muhammad Adnan; Rizwan, Muhammad Shahid; Arif, Muhammad Saleem; Yousaf, Balal; Ashraf, Muhammad; Xiong Shuanglian, Xiong Shuanglian; Rizwan, Muhammad; Mehmood, Sajid; Tu, Shuxin (2016-10-01)
The present study was done to elucidate the effects of vanadium (V) on photosynthetic pigments, membrane damage, antioxidant enzymes, protein, and deoxyribonucleic acid (DNA) integrity in the following chickpea genotypes: C-44 (tolerant) and Balkasar (sensitive). Changes in these parameters were strikingly dependent on levels of V, at 60 and 120 mg V L-1 induced DNA damage in Balkasar only, while photosynthetic pigments and protein were decreased from 15 to 120 mg V L-1 and membrane was also damaged. It was...
