As in medical X-rays, the densest tissues are depicted by the lightest colors, whereas the tissues lightest in density show up as the darkest colors.
Compared with diamond the postulated L-PHOD and Z-PHOD carbons are ~ 20% softer in hardness and weaker in tensile strength but ~ 10% lighter in mass densities due to their larger internal channels associated with the octagon rings, implying their potential applications as light-weight superhard materials.
The amount of radioactivity is expressed in density light units (DLU) per square millimetre.
Autoradiogram quantification was expressed in density light units (DLU) per square millimetre.
After 1, 5, 10, 20, 30, 45, 60, 75 and 90 days of incubation, a portion of each soil was taken for the study of in density (light and heavy) and soluble (hot water and cool water) OC fractions.
The experimental observations are then discussed in the light of density functional theory (DFT) combined with non-equilibrium Green's function (NEGF) calculations, estimating the transmission coefficients trough different paths for a PDI8-CN2 molecule in gas phase.
The advantageous properties such as low in density and light in weight can reduce the self-weight of structure, by all means, lowering the project cost and time.
Owing to the unique exceptional 3D carbon bi-frameworks of enhanced electrical conductivity and flexibility, the as-prepared graphene aerogel carbon texture hybrid presents an ultra-light feature (0.07 g cm−3 in density), with highly effective electromagnetic interference (EMI) shielding performance up to 27 dB and 37 dB (in the X band region) at thicknesses of 2 and 3 mm, respectively.
Although the peak of IFT complex B in the dyf13 mutant shifted slightly to a lighter density in the gradient, the IFT complex B proteins still comigrated with each other.
Therefore, the difference in density between the light catalyst and dense adsorbent particles should be as small as possible.
The error in determining the effective atomic number is less than 5% for Zeff>25 and less than 10% for light materials (Zeff<15), while the error in density estimation is always smaller than 3%.
