The production of hyperpolarized xenon by means of spin exchange optical pumping (SEOP) is described. This method yields a ~10000-fold enhancement of the nuclear spin polarization of Xe-129 and has applications in nuclear magnetic resonance spectroscopy and imaging. Examples of gas phase and solution state experiments are given.

Gases that seem harmless at atmospheric pressure can induce behaviors like narcosis under hyperbaric conditions. Conventional hyperbaric pressure chambers are costly and labor-intensive. This study presents a straightforward, low-cost method for examining xenon's effects on Drosophila melanogaster at moderate pressures below 4 atm.

Arc Length Function

The arc length function represents the total distance traveled along a smooth curve measured from a fixed starting point to a variable endpoint. For curves that are continuous and differentiable, arc length provides a precise way to quantify distance when straight-line approximations are insufficient.To derive arc length, the curve is divided into many small segments. Each segment is approximated by a straight line whose length depends on the horizontal and vertical changes over that interval.

Arc Length of a Curve

In engineering applications like roller coaster design, cable installation, and railway construction, determining the precise length of a curved path is essential. These paths are rarely straight and often follow smooth, continuous curves that require accurate measurement for effective planning.To estimate the length of a curve, the path is initially divided into small segments. Each segment is approximated by a straight line connecting two nearby points on the curve. The sum of these linear...

Arc Length of Space Curves

Arc length represents the total distance traveled along a curve in space. For a moving object such as a helicopter, the path can be modeled by a vector-valued position function\begin{equation*}\mathbf{r}(t)=\langle x(t),y(t),z(t)\rangle\end{equation*}where t denotes time. Unlike displacement, which measures only the straight-line distance between two points, arc length accounts for every change in direction along the trajectory.To calculate arc length, the interval of motion is divided into...
FAQs
Applying voltage across the electrodes first ionizes the pressurized xenon, creating a conductive plasma that sustains the arc. This plasma is the emitting region, converting electrical energy into intense radiation across ultraviolet, visible, and near-infrared wavelengths. The electrode-to-plasma arrangement therefore determines how the lamp maintains illumination and supplies a broad optical signal for experiments.
Filters allow researchers to select or restrict portions of the lamp's ultraviolet, visible, or near-infrared output. This tunability lets an experiment expose a sample or detector to a more controlled spectral range rather than the full emission. As a result, researchers can relate observed photochemical, fluorescence, or materials responses to the chosen illumination.
The source is useful because its broad output resembles natural sunlight across relevant ultraviolet, visible, and near-infrared regions. Researchers can therefore use controlled illumination to investigate how photosensitive materials respond under reproducible optical conditions. This approach connects laboratory testing with sunlight-related behavior while allowing the illumination to be selected and maintained more systematically.
A basic setup begins by applying voltage between the electrodes so the xenon gas ionizes and the arc forms. Researchers then use the resulting emission directly or place filters in the optical path to control the spectral range. The selected light is directed toward a reaction, sample, or instrument, depending on the measurement or experiment.
During UV-visible spectroscopy, the lamp supplies intense, broad-spectrum illumination for examining a sample under optical conditions. It also provides controlled illumination for fluorescence measurements. Stable output and tunable filtering help researchers select relevant wavelengths and maintain reproducible conditions, allowing them to investigate optical behavior across samples or measurement settings without changing the basic light source.
In chemistry, it is especially valuable when researchers need to connect illumination with a light-driven reaction pathway. The lamp can expose a reaction to intense, selected radiation, while its broad output supports testing across ultraviolet, visible, and near-infrared regions. The same controlled approach helps evaluate photosensitive materials and compare their responses under reproducible experimental conditions.
Stable, broad-spectrum illumination makes the lamp useful for calibrating optical instruments under reproducible conditions. Researchers can use its ultraviolet, visible, and near-infrared output as a controlled optical source while assessing instrument response. Tunable filters further allow calibration or performance checks under selected spectral regions rather than only under the lamp's complete emission.
