Design and synthesis of silver nanoparticle anchored poly(ionic liquid)s mesoporous for controlled anticancer drug delivery with antimicrobial effect

Nural, Yahya | Yabalak, Erdal

Owing to the importance of drug delivery, the synthesis of advanced nanomaterials for targeted drug delivery plays a considerable role in medical treatment. One of the most prominent nanomaterials is PIL, which is used as controlled anticancer drug delivery and significantly improves the half-life and antitumor effect. In this study, a stable and effective drug carrier containing silver nanoparticles was reported for the drug delivery with an antimicrobial effect, and the capability of the drug carrier . PILP was synthesized by radical polymerization, and silver nanoparticles were anchored into PIL voids by in-situ reduction, which developed the adsorption antimicrobial effect and capability of the drug carrier. The synthesized nanocomposite was characterized. The Ag-PILP nanocomposite sho...

Oleik asidin mikrodalga yardımlı esterleştirilmesi ve biyodizel üretimi

Bölük, Servet.

ÖZET OLEİK ASİDİN MİKRODALGA YARDIMLI ESTERLEŞTİRİLMESİ VE BİYODİZEL ÜRETİMİ Bu çalışmada, oleik asidin mikrodalga yardımlı esterleştirilmesi metanol ve bir iyonik sıvı olan 1-butil-3-metilimidazolyum hidrojen sülfat ([BMIM]HSO4) katalizörlüğünde gerçekleştirilmiştir. Optimum koşulları (katalizör miktarı, reaksiyon süresi, iyonik sıvı miktarı ve sıcaklık) araştırmak için parametrik çalışmalar yapılmıştır. Bununla beraber benzer koşullarda farklı katalizör ve ısıtma sistemlerinin etkileri incelenmiştir. Sonuç olarak maksimum verim %20 iyonik sıvı, 120 °C sıcaklık, 9:1 metanol/oleik asit molar oranı ve 90 dakikalık reaksiyon süresi sonunda %90,87 olarak elde edilmiştir. Oleik asit esterleştirilmesi mikrodalga, ultrasonik ve mekanik yöntemler kullanılarak gerçekleştirilmiş ve böylece farklı y...

Influence of the addition of various ionic liquids on coal extraction with NMP

Sönmez, Özgür | Gözmen, Belgin

In this work, two Turkish coals were extracted with N-methyl-2-pyrrolidone (NMP) and NMP containing a small amount of ionic liquids (ILs) under reflux conditions at atmospheric pressure. The effects of coal type, ionic liquid type, ionic liquid-to-coal ratio, and ultrasonic interactions on extraction yield were investigated. The ILs used were: 1-butyl-3-methylimidazolium chloride ([Bmim]Cl), 1-buty-4- methylpyridinium chloride ([Bmp]Cl), 1-ethyl-3-methylimidazolium chloride ([Emim]Cl), and 1-butyl-2,3-dimethylimidazolium chloride ([Bdmim]Cl). It was found that the extraction yield of coals using NMP/ILs varied with coal type, IL type and amount of IL. ILs were effective on the extraction of Afsin-Elbistan (AE) lignite, but not on the extraction of Üzülmez (UZ) coal. A significant in...
