High Precision Coulometric Titration of Uranium
An improved method for the coulometric assay of uranium and uranium oxide has been developed based on the electrogeneration of Tif II in H2SO,, using Fe(lI) as a catalyst. The endpoint is determined amperometrically. Hydrogen peroxide is used as the oxidant in the dissolution of the uranium to avoid interferences from nitrate. The precision of the method as indicated by the standard deviation o...
متن کاملA High-Frequency Transconductance Method for Characterization of High-k Border Traps in III-V MOSFETs
A novel method that reveals the spatial distribution of border traps in III-V MOSFETs is presented. The increase in transconductance with frequency is explored in a very wide frequency range (1Hz to 70 GHz) and a distributed RC network is used to model the oxide and trap capacitances. An evaluation of vertical InAs nanowire MOSFETs and surface-channel InGaAs MOSFETs with Al2O3/HfO2 high-κ gate ...

متن کاملHigh frequency skin ultrasonography in systemic sclerosis
Background: Systemic sclerosis is an autoimmune connective tissue disorder which is characterised by cutaneous and internal organ fibrosis. Raynaud’s phenomenon is the earliest feature and may precede the onset of the disease by months to years. The heart, lungs, gastrointestinal tract, kidneys and other organs may be involved. Our aim was to evaluate skin thickness and echogenicity in systemic...
