Dusting Research, Experiment and
Hypothesis
Improve Virtual Microscope Search for
Interstellar Dust Particles in Al Foil.
By Star Dust @ Home Project Duster
Fatima EL AISSAOUI
Virtual Microscope Images Dusting Research on observed Technical errors of
Reflected Movies:
-Carbon Contamination of the Al foil.
-Beam light projection errors
-Objects, particles semi light absorption artifacts.
Raised Question:
- Carbon contamination in Al foils Versus Carbon charged particles , chondrites (
Interstellar Carbon)
- How can we distinguish between C charged particles in Foils from Carbon
contamination residue caused by oil pumping of instrument during scanning?
Conclusion:
- If Al foil is more prone to Carbon Contamination during scanning than Aerogel
tiles then Aerogel is likely better for studying and looking for Interstellar Carbon
molecules in Star Dust or interplanetary Particles that we might have caught in the
Tray.
Experiment Al foil under Light microscope Objectives:
- Exploration of Al foil under light microscope
- Experiment of observed similar Movie errors eg( figures 1,2)
Results:
Figure1:
Too
Much
Light
Projection
Figure2: Less light
on right side Angle of
Projection Error
Observation:
Coincidental Similarity of Technical Errors from Optical view Stand Point Movies look similar
but The causes might be different for SEM:
In Light Microscope Errors such as Semi light absorption of Foils were due to the following:
- VARIATIONS IN THE AMOUNT OF BEAM LIGHT BEING PROJECTED TO
THE FOILS.
- WORKING DISTANCE BETWEEN LIGHT SOURCE AND WORKING AREA
OF FOIL SHEET.
- ANGLE OF LIGHT FROM THE LIGHT SOURCE LED.
- ANGLE LOCATION OF THE LIGHT SOURCE DEVICE FLASH LIGHT ITSELF :
Lateral, Median, Superficial from which focus area is being scanned with 4X 10X light Microscope
magnification Lens.
Hypothesis I think will solve this light source caused errors:
Optical Solution using Light compound Microscope doing similar Study using different
Material.
Copper Foil experiment:
using same technique previously seen in foils.
Material USED:
Copper
Model Number 38GA
Number of Items 1
Part Number 38GA
Style roll
UNSPSC Code 24140000
ASIN: B0042SWYUA
Results:
Copper foil been observed under microscope figures(1,2,3)
Figure 1: Oxidation like view old foil Figure 2: Debris in colors fiber like in Red
Figure 3: transparent crystal like Debris in blue
Observation:
Copper foil not only given back better images with less light source contamination and more
transparency or clarity but even reflected particles, oxidation and debris in colors! For further
precisely locating them on the Movie ID or the VM software downloaded images.
Unexpected findings observations
Fiber like particles figure 2
Glass like particles figure 3
Oxidation like areas of Copper material figure 1
Blueish sky like particles figure 2
Conclusion:
It has been a thought that only fluorescent elements detecting instruments such as X-ray
fluorescence (XRF), X-ray diffraction (XRD) and others will reflect particles charge back in
colors and that will be the analytical study of the elements carried out by those dust particles if
they are charged with like Fe ,C , N, Crystalline so on using those most advanced instruments
and synchotron micro-probe techniques to study the molecules with SEM and other
instruments.
So Copper optically does reflect back images in colors that are much clear to locate particles we
looking for and also the surrounding debris in the surface of foil this was not expected and the
first advantage is copper umber color refracts the white light wavelengths they become
absorbed other than reflected back and regardless the light projected increase it does not make
the foil too bright which leads to white surface and invisible particles instead it projects more
objects and particles that are on surface of the foil in colors the more light intensity increases
the more color the particles absorb and reflect back to in details.
Copper does probably act as a prism for the projected beam light which enabled the colored
debris and see send their shapes to the View of Software loaded images from the light
microscope 4X magnifying lens, yet are the colors of debris any indication of what they might
be composed of or just a charge from Copper prism mechanism We just noted?
Supporting Research Data on Optics Light and Color:
Why I think this Hypothesis of using Copper Material might be useful for future
projects in search of Cosmic Particles interstellar and Interstellar Exploration projects
in which we use Foil Materials:
Light may be reflected, absorbed, or refracted by objects. We typically think of shiny objects
reflecting light, but all objects reflect light. In fact, for an object to be visible, it must reflect some light
back to our eyes. The color of an object depends on the wavelengths of the light it reflects. When white
light strikes the red petals of a rose, the petals absorb all wavelengths of light, except for red, which it
reflects back to our eyes. The green stem and leaves of the rose absorb all wavelengths of light, except
for green, which they reflect. Since black is not a color that is present in visible light, objects that
appear black absorb all colors of light and reflect little or no color. Object that appear to be white
reflect all colors of visible light.”
~ http://www.uzinggo.com/color-absorption-reflection-light-heat-energy/color/physical-science-
middle-school (Color Absorption and Reflection: Light into Heat Energy Lesson article )
The color of an object or material is determined by the wavelengths it absorbs and those it
reflects. An object has the color of the wavelengths it reflects. A material that reflects all
wavelengths of visible light appears white. A material that absorbs all wavelengths of visible
light appears black. A green lime absorbs most wavelengths but reflects green, so the lime
looks green. The color that an object appears to the eye depends on another factor besides the
wavelengths the object absorbs and reflects. An object can reflect only wavelengths that are in the light
that shines on it. In white light, a white object reflects all the wavelengths of visible light and appears
white. If you shine only red light on a white piece of paper, however, the paper will appear red, not
white, because only red light is available to be reflected. In summary, two factors determine the color
of an object: first, the wavelengths that the object itself reflects or absorbs, and second, the wavelengths
present in the light that shines on the object.”~ ( Article Color reflection and Absorption)

Disadvantages triggering Questions :
- Copper material composition chemical elements interference with particles
- semi conductive bio static material in search for life in space this is not a good option
- oxidation viewed on the experiment.
-Copper color interference with flurecence instruments when studying elements will it interfer or not?
Further research and Experiment subject:
What was seen in the copper surface under light microscope ? All what was observed in colors and
different shapes tiny debris and particles. Could it be reflection of elements inside them?

look for linear scale physical quantity.
Find the Operating Voltage applied to the beam LED light ( Removable Battery ) 3.8 V
Find angle of light eg 45 degree angle
2) measure foil length + width
3) find intensity of Beam light being projected
how much light applied to how much foil:
How can light intensity be calculated?
Convert the distance that you measured into meters. For example, if the point at which you want to
calculate the light intensity is 81 cm away from the light source, report your answer as 0.81 meters. ...
This answer is the surface area of your relevant sphere of light intensity.

Resolution limits Light Microscope Vs Scanning Electron Microscope and
Transmission Electron Microscopy:
In a compound microscope, the wavelength of the light waves that illuminate the
specimen limits the resolution. The wavelength of visible light ranges from about
400 to 700 nanometers. The best compound microscopes cannot resolve parts of a
specimen that are closer together than about 200 nano- meters.
In a SEM, an electron beam scans rapidly over the surface of the sample specimen
and yields an image of the topography of the surface. The resolution of a SEM is
about 10 nanometers (nm). The resolution is limited by the width of the exciting
electron beam and the interaction volume of electrons in a solid.
Standard household foil : 0.016 mm (0.63 mils) thick,
Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils
thinner than this become slightly permeable due to minute pinholes caused by the
production process.
