Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

5.6K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Kinetic Energy00:23

Kinetic Energy

39.3K
Kinetic energy is the ability of an object in motion to do work or enact change. It can take on many forms. For instance, water flowing down a waterfall has kinetic energy. In biological systems, particles of light travel and are absorbed by plants to create chemical energy. Animals consume the chemical energy and give off molecules that carry their scent through the air. They also generate kinetic energy when they run away from predators. Entire systems also possess kinetic energy, like the...

Protein Dynamics in Living Cells

2.2K
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

    Area of Science:

    • Atomic and Molecular Physics
    • Physical Chemistry
    • Spectroscopy

    Background:

    • Velocity map imaging (VMI) is a key technique for studying light-matter interactions.
    • Existing VMI methods provide limited kinetic energy and angular information.
    • There is a need for advanced imaging techniques to probe photophysical processes with higher resolution.

    Purpose of the Study:

    • To demonstrate the kinetic energy-broadened spatial map imaging (KESMI) technique as a novel method for analyzing photophysical processes.
    • To recover kinetic energy (KE) and angular recoil information of photoelectrons (PEs).
    • To develop a global model for understanding KESMI patterns in photoelectron spectroscopy.

    Main Methods:

    • Utilizing a VMI system in different out-of-focus modes to perform KESMI.
    • Analyzing characteristic stripe and step patterns in vertical intensity profiles of KESMIs.
    • Developing and applying a global model to interpret KESMI signatures.
    • Simulating and measuring KESMIs for Ar ionization and H2O quantum state ionization.

    Main Results:

    • KESMI successfully recovers KE and angular recoil information from photophysical processes.
    • A global model was developed to understand the stripe and step patterns observed in KESMIs.
    • The model accurately relates observed KESMI features to predicted discrete KEs and angular distributions.
    • The velocity distribution of photoelectrons from H2O ionization was derived using KESMI, validating the technique.

    Conclusions:

    • KESMI is a feasible and powerful technique for analyzing photophysical processes.
    • The developed global model provides a robust framework for interpreting KESMI data.
    • KESMI offers a promising alternative or complement to VMI for detailed photoelectron spectroscopy.
