Nanoscale Microstructural Analyses by Atom Probe Field Ion Microscopy
Recent progress in atom probe field ion microscopy (APFIM) and its applications to nanoscale microstructural studies of metallic materials are reviewed. By employing a three dimensional atom probe (3DAP), it is possible to map out elemental distributions in the real space with almost an atomic resolution, and chemical analysis of interfaces and nanoparticles can be made with improved accuracy i...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
determination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid
چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...
15 صفحه اولAutomated atom-by-atom 3D reconstruction of field ion microscopy data
An automated procedure has been developed for the 3D reconstruction of field ion microscopy (FIM) data that maintains the atomistic nature of the technique. FIM characterises individual atoms on the surface of a specimen, that is evolving subject to the process of field evaporation, in a series of 2D time-ordered images. It’s unique spatial resolution enables the direct imaging of crystal defec...
متن کاملCold-atom scanning probe microscopy.
Scanning probe microscopes are widely used to study surfaces with atomic resolution in many areas of nanoscience. Ultracold atomic gases trapped in electromagnetic potentials can be used to study electromagnetic interactions between the atoms and nearby surfaces in chip-based systems. Here we demonstrate a new type of scanning probe microscope that combines these two areas of research by using ...
