Sintering and humidity-sensitive behaviour of the ZnCr2O4-K2CrO4 ceramic system
Bayhan, M; Hashemi, T; Brinkman, AW (Springer Science and Business Media LLC, 1997-12-15)
Solid state reaction at elevated temperatures and the sintering behaviour of zinc chromite formed by zinc oxide and chromite oxide were investigated. Crystalline structure, surface and fractured morphologies and humidity-sensitivity characteristics of ZnCr2O4-K2CrO4-CuO were studied. The fired ceramic body, which proved to be mainly constructed from ZnCr2O4 spinel grains, was porous. The humidity characteristics of the sensor showed that the resistance decreased as a logarithmic function with an increase in...
Sinter hardening studies of ASTALOY 85 Mo powder with varying copper contents /
Dinçer, Mehmet; Ögel, Bilgehan; Durlu, Nuri; Department of Metallurgical and Materials Engineering (2014)
In this thesis study, the effect of sinter hardening on mechanical properties of Astaloy 85 Mo (Fe - 0.85% Mo) powder with addition of 0.8% C and varying copper contents (1% Cu, 2% Cu) was examined. Powder mixes were compacted under 600 MPa. After compaction, the samples were sintered at 1120oC under endogas from methane in an industrial sintering furnace and were sinter-hardened with three different cooling rates (0.5oC/sec., 1.5oC/sec., 3oC/sec.). The study revealed that the cooling rate does not make cri...
Dispersion Corrected DFT Study of Pentacene Thin Films on Flat and Vicinal Au(111) Surfaces
METE, ERSEN; Danışman, Mehmet Fatih (2015-02-19)
Here we present a density functional theory study of pentacene ultrathin films on flat and vicinal [(455)] Au(111) surfaces. We have performed crystal and electronic structure calculations by using PBE and optB86b-vdW functionals and investigated the effects of long-range van der Waals interactions for different coverages starting from a single isolated molecule up to 4 monolayers of coverage. For an isolated molecule both functionals yield the hollow site as the most stable one with the bridge-60 site bein...
