The polarity (whether or not it can be used directly by ribosomes to make proteins) of single-stranded RNA viruses largely determines the replicative mechanism; the other major criterion is whether the genetic material is single-stranded or double-stranded.
Apparent contradictions emerging from the material were singled out to allow for the comparison of the information given by different informants.
Graphene-based materials are single- or few-layer platelets that can be produced in bulk quantities by chemical methods.
X-ray diffraction results revealed that (i) all of these materials were single phase, and (ii) the crystal structures of La1−xAx′Co1−yBiyO3−δ, La1−xSrxMO3−δ, La1.867Th0.100CuO4−δ, Nd2−xAx′CuO4−δ, and YBa2Cu3O7−δ were cubic, orthorhombic, tetragonal (T structure), tetragonal (T′ structure), and orthorhombic, respectively.
X-ray diffraction patterns revealed that all the prepared materials are single-phase spinels.
To perform similar experiments with non-crystalline material, that is single particles, the resolution-dependent fading of the signal present in an image (or average of images) has to be determined.
It is shown that the ozone absorption is practically a single function of the gas/liquid ratio while the removal efficiency of the odorous material is a single function of the ozone dose for a specified U-tube configuration.
In Mr. Gormley's case, the material is a single strand of aluminum rod approximately 1 inch square (12.7 mm).
The X-ray diffraction profile confirms that the as-synthesized material is of single phase, monoclinic MgBO2(OH).
It can be seen that the loss in productivity from mining out-of-seam material is the single biggest contributor to the cost.
The XRD profiles (Fig. 1) for the MBH-NON, MBH-CTAB, MBH-SDS and MBH-Triton samples show that the as-prepared material is of single phase and high purity.
