Preparation of Samples for Electron Microscopy01:20

Preparation of Samples for Electron Microscopy

To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...

Gravimetry: Inorganic And Organic Precipitating Agents

In gravimetry, the precipitant is chosen carefully to obtain a pure solid that can be easily filtered. Common inorganic precipitants can be used to determine several cations and anions. In some cases, the formation of the same precipitate can be used to determine the cation and the anion. For example, the reaction of barium and chromate ions to give barium chromate is used to determine both barium and chromate. However, precipitates such as hydroxides, oxalates, and metal ammonium phosphates...
Sample Preparation for Analysis: Advanced Techniques01:08

Sample Preparation for Analysis: Advanced Techniques

Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...

    Summary
    This summary is machine-generated.

    Mercury in lunar samples may form the tenuous lunar atmosphere. Its presence suggests a subsurface cold trap and offers insights into lunar rock orientation through surface-related mercury analysis.

    Area of Science:

    • Planetary Science
    • Geochemistry
    • Lunar Science

    Background:

    • Mercury is present in lunar samples and can volatilize at lunar daytime temperatures.
    • Volatilized mercury may contribute to the tenuous lunar atmosphere.
    • Understanding mercury's behavior is key to comprehending lunar atmospheric processes and surface composition.

    Purpose of the Study:

    • To investigate the presence and behavior of mercury in lunar samples.
    • To determine if mercury can escape the lunar atmosphere via nonthermal mechanisms.
    • To explore the implications of mercury distribution for subsurface reservoirs and lunar rock orientation.

    Main Methods:

    • Analysis of mercury content in lunar core samples.
    • Investigation of mercury volatilization at simulated lunar temperatures.
    • Comparative analysis of mercury in exterior versus interior rock samples.

    Main Results:

    • Lunar samples contain mercury, which volatilizes at lunar daytime temperatures.
    • An increase in mercury with depth in core samples indicates a subsurface cold trap.
    • Differences in mercury amounts on exterior and interior samples may reveal rock orientation.

    Conclusions:

    • A subsurface cold trap likely exists on the Moon, influencing mercury distribution.
    • Nonthermal escape mechanisms may be involved in mercury's atmospheric presence.
    • Surface-related mercury analysis can provide information on lunar rock orientation.
