$X-ray Diffraction of Biological Samples$ 01:10

X-ray Diffraction of Biological Samples

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...

X-ray Crystallography

X-ray Crystallography

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

$Interference and Diffraction$ 02:18

Interference and Diffraction

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.

Radial System Protection

Radial System Protection

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Assessment of radial pulse

Assessment of radial pulse

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Background:

X-ray diffraction (XRD) experiments are often limited by poor signal-to-background ratios.
Undesirable Bragg reflections from sample environment windows reduce detector dynamic range and sensitivity.

Purpose of the Study:

To demonstrate the efficacy of a 3D printed radial collimator in XRD.
To improve signal-to-background ratios and suppress unwanted reflections in sensitive X-ray diffraction techniques.

Main Methods:

Additive manufacturing (3D printing) of a steel radial collimator.
Application in X-ray powder diffraction and grazing incidence X-ray diffraction.
Alignment using X-ray fluorescence and specific data analysis.

Main Results:

Achieved signal-to-background ratio improvement up to 100x.
Suppressed unwanted Bragg reflections from sample windows by over 3 x 10^5.
Enabled significantly higher sensitivity in vacuum, gas, and liquid sample environments.

Conclusions:

3D printed collimators offer a flexible, affordable solution for optimizing XRD experiments.
This technology enhances data quality and sensitivity, particularly within challenging sample environments.
Customizable 3D printed collimators do not compromise diffractometer functionality.
