The utilization smart hydrogels and composites with controllable porosity in the preparation of metal nanocatalyst

Sahiner N., Ozay O., Sagbas S., Yasar A., Aktas N., Canakkale Onsekiz Mart University, TR

There is great need for versatile and smart support materials. As many industrial and biologic reactions take place in water (green chemistry), systems that operates in water and mechanically durable, flexible with controllable porosity, and [...]

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 [...]

Fabrication and characterization of liquid metal-based micro-electromechanical DC-contact switch for RF applications

Cagatay E., Damgaci Y., Cetiner B.A., Biyikli N., Bilkent University - UNAM, TR

Electrowetting-on-dielectric (EWOD) is the phenomenon in which the wetting properties of a liquid are modified by the influence of an applied electric field. By EWOD, a conducting or non-conducting liquid can be moved using a [...]

Flexible Organic-Inorganic Core-Shell Nanofibers by Electrospinning and Atomic Layer Deposition

Kayaci F., Ozgit-Akgun C., Donmez I., Biyikli N., Uyar T., Bilkent University, TR

We report on the fabrication of organic-inorganic core-shell nanofibers by using two-step approach; electrospinning and atomic layer deposition (ALD). In the first step, nylon (polymeric organic core) nanofibers having different average fiber diameters were electrospun [...]

Template-based synthesis of AlN hollow nanofibers via plasma-enhanced atomic layer deposition

Ozgit-Akgun C., Kayaci F., Donmez I., Uyar T., Biyikli N., Bilkent University, TR

We report on the synthesis of AlN hollow nanofibers by plasma-enhanced atomic layer deposition (PEALD) using electrospun polymeric nanofibers as templates. Three templates with different average fiber diameters were obtained by electrospinning of polymeric solutions [...]
