Interference and Diffraction02:18

Interference and Diffraction

51.9K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

X-ray Diffraction of Biological Samples01:10

X-ray Diffraction of Biological Samples

4.7K
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are  scattered by the electron clouds around the sample atoms. The  X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Nuclear Stability03:18

Nuclear Stability

23.0K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.
To hold positively charged protons together...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Area of Science:

  • Solid-state chemistry
  • Materials science
  • Crystallography

Background:

  • Deuterated ice XVII is a metastable solid water polymorph with hexagonal channels.
  • Understanding guest molecule incorporation in ice structures is crucial for materials science.
  • Previous studies on ice II showed different guest molecule interactions.

Purpose of the Study:

  • To investigate the structural behavior of deuterated ice XVII when filled with Ne and O2.
  • To determine the location and arrangement of guest molecules within the ice XVII channels.
  • To analyze the impact of guest molecules on the host ice's symmetry and stability.

Main Methods:

  • In situ neutron diffraction at the ILL (France) was employed.
  • Powder patterns were collected for Ne-filled ice XVII (20-50 K) and O2-filled ice XVII (4.6-90 K).
  • Rietveld refinement and difference Fourier techniques were used for structural analysis.

Main Results:

  • Ne atoms and O2 molecules were located within the hexagonal channels of deuterated ice XVII.
  • Guest molecules adopted spiral configurations, preserving P6122 symmetry for Ne and reducing it to P61 for O2.
  • Enhanced Ne absorption was observed compared to ice II, attributed to favorable host-guest contacts.
  • Attractive O-D interactions in O2-filled ice XVII contributed to structural stabilization.

Conclusions:

  • Deuterated ice XVII can incorporate Ne and O2 molecules within its channels.
  • The arrangement of guest molecules influences the symmetry of the ice structure.
  • Host-guest interactions play a significant role in the stability of filled ice structures.
