The phrase "a sample thickness" is correct and usable in written English.
It can be used when referring to the measurement or specification of the thickness of a sample in various contexts, such as scientific experiments or material testing.
Example: "The results of the experiment were significantly affected by a sample thickness of 2 millimeters."
Alternatives: "a specimen thickness" or "a test thickness".
Tumor tissue can be very optically dense, calling for a sample thickness of 10 μm thick or less, and even then every optical interface scatters light quite strongly.
% RBC-PCHMs exhibits an efficient absorption bandwidth (reflection loss less than −10 dB, > 90% absorption) more than 3 GHz with a sample thickness of < 2 mm in the X band at the temperature from 300 to 523 K.
The reflection loss (RL) was calculated from complex permittivity and permeability data and maximum RL of −37.7 dB at 10.2 GHz with a sample thickness of 2.5 mm and bandwidth of 0.53 dB.
The maximum photopolymerization quantum yield was about 21.2 mol einstein−1 for TMPTA with a sample thickness of 20 μm and a CBC content of 2.0 wt% under 0.5 mW cm−2 laser irradiation.
The results show that the rGO/porous Bi2Fe4O9 composite exhibits a maximum reflection coefficient of −71.88 dB at 13.8 GHz with a sample thickness of only 2.0 mm and an effective absorption bandwidth (reflection loss below −10 dB) of 4.24 GHz, greatly superior to the present graphene-based metallic oxide composite.
This unexpected observation highlights another unique feature of soft X-ray microscopy, i.e. high absorption contrast information not relying on labeled cellular components, at a 3D resolution of approximately 40 nm (half-pitch) and through a sample thickness of several micrometers.
The complex impedance data were obtained for prepared TiO2 and AgBr loaded TiO2 by employing a specially designed conductivity cell having a fixed sample thickness of 2 mm.
So, for a constant sample thickness, the brighter contrast in the image is related to a higher Bi content (ZBi = 83, ZGa = 31 and ZAs = 33).
Through comparison we unveil that both changes in the band structure resulting from a different sample thickness and the disorder induced by sample preparation and graphene/substrate interface are responsible for the MR behavior in the thickness variation.
For example, a low sample thickness is indicated by the presence of noise in the case of FTIR imaging data.
It can be seen that the peaks observed for the two base materials are also present in the simulant, albeit with peak broadening in the latter sample due to a larger sample thickness.
