Two different organic cations (structure directing agents, SDAs) have been selected because of their ability to drive the synthesis of zeolites towards the same microporous material, RUB-13 (RTH), both being organophosphorous compounds. These P containing structure directing agents are characterized by a high concentration of positive charge on the(More)
This paper studies the characterization of corrosion products formed on corroded and uncorroded copper-containing intrauterine devices stored at room temperature for a period of 30 months. The experimental techniques used were X-ray photo-electron spectroscopy and Auger electron spectroscopy. The compounds found were cuprite (Cu2O) and tenorite (CuO). The(More)
In this work a new ultrafast data collection strategy for electron diffraction tomography is presented that allows reducing data acquisition time by one order of magnitude. This methodology minimizes the radiation damage of beam-sensitive materials, such as microporous materials. This method, combined with the precession of the electron beam, provides high(More)
