In situ Measurements of Irradiation-Induced Creep of Nanocrystalline Copper at Elevated Temperatures Özerinç, Sezer; KING, William P. (Springer Science and Business Media LLC, 2016-11-01) We have measured irradiation-induced creep on nanocrystalline copper micropillars at elevated temperatures. The micropillars, which were approximate to 1 mu m in diameter and approximate to 2 mu m in height, were fabricated from magnetron-sputtered nanocrystalline copper films. The micropillars were compressed during 2.0 MeV Ar+ bombardment and the deformation measured in situ by laser interferometry. The creep rate was measured over the stress range 10-120 MPa at approximate to 200 degrees C. The results s...
In situ 3D monitoring of corrosion on carbon steel and ferritic stainless steel embedded in cement paste Itty, PierreAdrien; Serdar, Marijana; Akgül, Çağla; Parkinson, Dula; MacDowell, Alastair A; Bjegovic, Dubravka; Monteiro, Paulo JM (Elsevier BV, 2014-06-01) In a X-ray microcomputed tomography study, active corrosion was induced by galvanostatically corroding steel embedded in cement paste. The results give insight into corrosion product build up, crack formation, leaching of products into the cracks and voids, and differences in morphology of corrosion attack in the case of carbon steel or stainless steel reinforcement. Carbon steel was homogeneously etched away with a homogeneous layer of corrosion products forming at the steel/cement paste interface. For fer...
In situ multiphase fluid experiments in hydrothermal carbon nanotubes Gogotsi, Y; Libera, JA; Güvenç Yazıcıoğlu, Almıla; Megaridis, CM (2001-08-01) Hydrothermal multiwall closed carbon nanotubes are shown to contain an encapsulated multiphase aqueous fluid, thus offering an attractive test platform for unique in situ nanofluidic experiments in the vacuum of a transmission electron microscope. The excellent wettability of the graphitic inner tube walls by the aqueous liquid and the mobility of this liquid in the nanotube channels are observed. Complex interface dynamic behavior is induced by means of electron irradiation. Strong atomic-scale interaction...
In vivo solid phase microextraction sampling of human saliva for non-invasive and on-site monitoring Bessonneau, Vincent; Boyacı, Ezel; Maciazek-Jurczyk, Malgorzata; Pawliszyn, Janusz (2015-01-26) On-site sample preparation is an analytical approach based on direct sampling from the system under investigation. It has the advantage of combining sampling and sample preparation into a single step, thus generally is fast, minimizes the potential sources of error and eliminates the risks for analytes instability. For such analysis solid phase microextraction in thin film geometry (TF-SPME) can provide robust and convenient in vivo sampling, offering in the same time faster analysis and higher extraction r...
In situ creep measurements on micropillar samples during heavy ion irradiation Özerinç, Sezer; King, William P. (Elsevier BV, 2014-08-01) We report on the development of an in situ micropillar compression apparatus capable of measuring creep under heavy ion beam irradiation. The apparatus has a force resolution of 1 mu N and a displacement resolution of 1 nm. The experimental setup consists of a nanopositioner, a laser displacement sensor, and a microfabricated doubly clamped silicon-beam transducer. The system was tested by measuring the creep rate of amorphous Cu56Ti38Ag6 micropillars as a function of applied stress during room temperature ...
