From Synthesis Gas to a Clean Transportation Fuel Dimethyl Ether: New Nanocomposite Bifunctional Catalyst Pairs

Arslan A., Bayat A., Celik G., Dogu T., Middle East Technical University, TR

Diemethyl ether (DME) is a promising diesel fuel alternative due to its high cetane number and clean burning properties. Direct synthesis of DME from syngas has major thermodynamic advantages over the conventional process. Technological development [...]

A Novel Conducting Polymer for Biosensor Applications

Soylemez S., Ekiz Kanik F., Ileri M., Ozdemir Hacıoglu S., Toppare L., Middle East Technical University, TR

In this study, 2-(4-fluorophenyl)-4,7-di(thiophene-2-yl)-1H-benzo[d]imidazole, a novel monomer, was synthesized and its polymer was used for the immobilization matrix for cholesterol oxidase (ChOx). A novel cholesterol biosensor was generated. The designed conducting polymer based biosensor showed [...]

Finite Element Modeling of MEMS Piezoelectric Energy Harvester

Beker L., Muhtaroglu A., Ozguven H.N., Kulah H., Middle East Technical University, TR

This paper reports an improved method for modeling and optimization of a MEMS piezoelectric energy harvester (PEH) for a desired frequency range with maximum voltage output using finite element method. Single-degree-of-freedom and distributed parameter modeling [...]

Effects of Solvents on Dissolution of Photoresist in Parylene Microchannels

Ceylan Koydemir H., Kulah H., Ozgen C., Tosun I., Middle East Technical University, TR

This paper presents a detailed study for the effects of different types of solvents on dissolution of photoresist inside the parylene micro-channels, for the first time. Experimental results indicate that photoresist dissolution in dipolar aprotic [...]

Polyamide 6-Organoclay- Impact Modifier Nanocomposites

Isik I., Yilmazer U., Bayram G., Middle East Technical University, TR

Polyamide-6, organically modified montmorillonite, and ethylene/glycidyl methacrylate (E-GMA) and ethylene/butyl acrylate/glycidyl methacrylate (E-BA-GMA) terpolymers acting as impact modifiers for polyamide were melt blended in order to investigate the effects of component concentrations on the final [...]
