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 [...]

Bio-inspired Optoelectronic Digital Nose

Bayindir M., Yildirim A., Vural M., Yaman M., Bilkent University, TR

We introduce and demonstrate the capabilities of a novel integrated optoelectronic-microfluidic sensor array that can rapidly distinguish millions of, trace level volatile chemicals based on their spectroscopic fingerprints inside flexible optofluidic channels. The system consists [...]

Nano-structured Organically Modified Silica Thin Films for Functional Surfaces

Bayindir M., Yildirim A., Budunoglu H., Yaman M., Deniz H., Guler M.O., Bilkent University, TR

Organically modified silica (ormosil) nano-composites are unique materials that offer best of the both of organic polymers and inorganics, like mechanical flexibility together with good chemical durability [1]. Nano-porosity adds these hybrid materials extra-functionality (e.g., [...]

ABC: A double-conversion compiler/solver for nanoscopic calculus

Kulik I.O., Bilkent University, TR

The progress and demand of nanoscience, nanotechnology and molecular electronics is ultimately related to the progress and the perspectives of computational science. We report on the development of a new computing device which was termed [...]

Quantum Computation with Persistent-current Aharonov-Bohm Qubits and Qugates

Kulik I.O., Bilkent University, TR

We propose that Aharonov-Bohm effect can be used for quantum computation. The effect consists of existence of persistent currents in mesoscopic/nanoscopic loops of normal metal or semiconductor in a magnetic field perpendicular to loop. Three-site [...]

Hopping and Correlation Effects in Atomic Clusters and Networks

Kulik I.O., Bilkent University, TR

Exact solution for hopping and correlation effects in atomic clusters and mesoscopic/nanoscopic networks is outlined. The program translates the Hamiltonian operator of the cluster written in terms of second-quantized creation and annihilation operators, to sparse [...]
