"material sample" is correct and usable in written English.
It typically refers to a sample of a specific material, such as fabric, that is used as an example. For example, "The store provided a material sample of the shirt so I could check the texture and color."
This site contains some good reference material, sample application code, and a tutorial on porting applications from IPv4-only to dual stack capability in C, PERL, and Python.
Two current manufacturing methods were evaluated for each material sample: compression molding and ram extrusion.
In addition, the surface of each black material sample was examined using a FE-SEM (4500S, Hitachi, Tokyo, Japan).
Also, the thinner the spacer material sample, the more difficult it can be prepared (dicing and polishing) and handled.
Both the chamber and the glove box were installed in the Planetary Material Sample Curation Facility of JAXA (PMSCF/JAXA).
Experiments have been carried out to validate the FE modelling approach for a specific material sample (polyurethane (PU) foam).
For modeling elastic multi-link structures we refer to [35], see also [14, 36, 37]. Figure 6 Nonwoven material sample after thermobonding.
However, the absence of these elements was confirmed indirectly by inoculating the selected species of moulds on this medium (without an organic material sample).
The SPM system not only achieved a soft material sample such as cell surface information using SICM, but it also obtained mechanical properties of a sample using AFM.
A fiberglass material sample with a 3 mm (0.037λ) diameter through hole (perpendicular to the propagation direction of the wave) was tested with both lenses.
The thermal conductivity of ZrO2 particles is estimated using a semi-inverse application of the strong contrast technique for a buckypaper material sample.
