We illustrate the application of 1H(15N,αγ)12C resonant nuclear reaction analysis (NRA) to quantitatively evaluate the density of hydrogen atoms on the surface, in the volume, and at an interfacial layer of solid materials. The near-surface hydrogen depth profiling of a Pd(110) single crystal and of SiO2/Si(100) stacks is described.

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 in the...
FAQs
Thickness provides an integrated structural readout of a layer containing several interacting retinal cell populations, including bipolar, horizontal, amacrine, and Müller glial cells. An increase or decrease may therefore signal altered development, neuronal organization, or tissue health. The value is strongest when interpreted as evidence of structural change rather than as a direct count of any one cell type.
Optical coherence tomography and histological imaging both quantify inner nuclear layer thickness by locating its inner and outer boundaries, but they serve different measurement contexts. Optical coherence tomography provides a noninvasive structural assessment, whereas histological imaging examines tissue microscopically. Comparing results across these approaches can connect measurements from intact retina with microscopic observations of retinal structure.
The layer contains cell bodies of bipolar, horizontal, amacrine, and Müller glial cells, so its thickness relates to a region populated by both neuronal and glial elements. This composition places the measurement in the structural context of retinal circuitry and makes it useful for studying how retinal organization changes across developmental, pathological, or experimental conditions.
The measurement requires identifying the layer’s inner boundary and outer boundary in an optical coherence tomography scan or histological image, then calculating the distance between them. Recognition of both limits is central because the reported value depends on the interval selected. This workflow converts an image of retinal architecture into a quantitative structural measurement for research comparison.
Researchers can use the measure in studies of retinal development, neurodegenerative disease, injury, and treatment response. In each setting, thickness offers a structural indicator that can reveal whether retinal organization or tissue health differs across experimental or clinical contexts. Its usefulness extends from basic investigations of retinal circuitry to evaluating structural changes associated with disease or intervention.
A difference in inner nuclear layer thickness can indicate altered retinal development, neuronal organization, or tissue health, but it is an anatomical indicator rather than a complete explanation of the underlying change. Because the layer contains multiple cell types, interpreting the result requires linking the structural observation to the specific research context, such as circuitry, disease, injury, or treatment response.
