Coordination polymers are ideal synthons in creating high aspect ratio nanostructures, however, conventional synthetic methods are often restricted to batch-wise and costly processes. Herein, we demonstrate a non-traditional, frugal approach to synthesize 1D coordination polymers by in situ etching of zerovalent metal particle precursors. This procedure is denoted as the heterogeneous metal/ligand reaction and was demonstrated on Group 13 metals as a proof of concept. Simple carboxylic acids supply the etchant protons and ligands for metal ions (conjugate base) in a 1 : 1 ratio. This scalable reaction produces a 1D polymer that assembles into high-aspect ratio 'nanobeams'. We demonstrate control over crystal structure and morphology by tuning the: (i) metal center, (ii) stoichiometry and (iii) structure of the ligands. This work presents a general scalable method for continuous, heat free and water-based coordination polymer synthesis.

Electrostatic Stabilization of Alumina Nanopowder Suspensions Çınar, Simge (American Scientific Publishers, 2014-03-01) Electrostatic stabilization has an impact on a broad range of applications. Previous research has shown that concentrated alumina nanopowder suspensions can be stabilized at specific ranges of ionic strength and pH. This study investigated the stability of alumina nanopowder suspensions in terms of viscosity measurements as a function of different electrolyte concentration and suspension pH. Using alumina nanopowders with an average particle size of about 50 nm, stable suspensions were obtained with 0.020 ≤...
Simulation of equal channel angular pressing applied to produce structures with ultrafine-sized grains Karpuz, Pinar; Şimşir, Caner; Gür, Cemil Hakan (Inderscience Publishers, 2009-01-01) Severe plastic deformation methods are of great interest in industrial forming applications, as they give rise to significant refinement in microstructures and improvements in mechanical and physical properties. In the 'equal channel angular pressing (ECAP)', which is the most common method for production of ultrafine grained bulk samples, very high plastic strains are introduced into the bulk material without any change in cross section. In this study, the plastic deformation behaviour of the materials sub...
Surface-enhanced Raman scattering spectroscopy via gold nanostars Nalbant Esentürk, Emren (Wiley, 2009-01-01) Anisotropic metallic nanoparticles (NPs) have unique optical properties, which lend them to applications such as surface-enhanced Raman scattering (SERS) spectroscopy. Star-shaped gold (Au) NPs were prepared in aqueous solutions by the seed-mediated growth method and tested for Raman enhancement using 2-mercaptopyridine (2-MPy) and crystal violet (CV) probing molecules. For both molecules, the SERS activity of the nanostars was notably stronger than that of the spherical Au NPs of similar size. The Raman en...
Advances in protective layer-coating on metal nanowires with enhanced stability and their applications Bang, Junhyuk; Coşkun, Şahin; Pyun, Kyung Rok; Doğanay, Doğa; Tunca, Sensu; Koylan, Serkan; Kim, Dongkwan; Ünalan, Hüsnü Emrah; Ko, Seung Hwan (Elsevier BV, 2021-03-01) © 2020 Elsevier LtdThe demand for flexibility in transparent conductive electrodes(TCEs) is increasing due to the functionality demand and convenience of deformable electrodes. The high-cost and brittleness of the conventional indium tim oxide (ITO) films are obstacles to their utilization in TCEs. Metal nanowires are highly promising as substitutes for ITO. Metal nanowire electrodes achieved high-conductivity, high-transparency, and high-stretchability through the development of fabrication technology. Nev...
Resonance-Based Temperature Sensors using a Wafer Level Vacuum Packaged SOI MEMS Process Aydın, Gülşah Demirhan; Akın, Tayfun (VBRI Press AB, 2020-01-01) This paper reports the development of resonance-based temperature sensors using a wafer level vacuum packaged SOI MEMS process which is normally used to implement various MEMS sensors, including MEMS gyroscopes and accelerometers. Implementing MEMS temperature sensors in such a MEMS process together with sensitive MEMS sensors allows obtaining temperature data, which is very useful for the compensation of a number of parameters of these MEMS sensors for obtaining improved performance from these sensors.
