¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

1.2K
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Atomic Emission Spectroscopy: Lab

263
AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...

  • Materials Science
  • Solid State Physics
  • Physical Chemistry

Background:

  • Metal-hydrogen systems are crucial for energy storage and catalysis.
  • Understanding defect evolution during hydrogen cycling is vital for material stability.
  • In situ characterization methods are needed to observe dynamic processes.

Purpose of the Study:

  • To develop and validate a novel system for complex in situ research of metal-hydrogen systems.

  • Integration of a radioisotope positron source and positron annihilation spectroscopy (PAS).
  • Complementary analysis using scanning electron microscopy (SEM), X-ray diffraction (XRD), and hydrogen sorption-desorption measurements.

Main Results:

  • The developed system enables in situ defect structure investigation at temperatures up to 900 °C and pressures up to 50 bar.
  • One cycle of magnesium hydrogenation-dehydrogenation led to the accumulation of irreversible hydrogen-induced defects.
  • PAS, SEM, XRD, and sorption studies provided a comprehensive understanding of the magnesium-hydrogen system.

Conclusions:

  • The novel system is effective for in situ studies of metal-hydrogen interactions and defect evolution.
  • Hydrogen cycling in magnesium results in permanent structural damage.
  • Combined techniques offer a powerful approach to characterize hydrogen-affected materials.
