"weaker intensity" is correct and usable in written English.
It is often used when talking about something that has diminished in strength or power. For example, "The rains came in with a weaker intensity this year than last."
The conventional interpretation is that the weaker intensity is associated with small crystallites and the more intense spots with larger crystallites that scatter more strongly (see, for example, Brindley, 1945 ▶; Gonzalez, 1987 ▶).
Unlike the weaker intensity EL illumination the high intensity LED illumination enabled shorter exposure times and allowed multi-wavelength illumination without the need to physically change the excitation strip, thus making spectrum excitation of multiple fluorophores possible increasing the versatility of the detector platform for a variety of optical detection assays.
During southern winter months the post-sunset ESF development is relatively infrequent over South America due to the generally weaker intensity of the sunset zonal electric field, which, however, is critical in determining the equatorial spread F (ESF) development under magnetospherically disturbed conditions.
The weaker intensity peaks in Fig. 8f originate from the non-uniform illumination.
For their prepared sample, typical upconversion emission was observed but with much weaker intensity than that of bulk crystal [15].
However, some weaker intensity evodiamine characteristic peaks were still detectable in the physical mixture, as shown in Fig. 3C (b).
Harder and rougher bottom types such as rocky outcrops or coarse sediment typically return stronger intensities (high backscatter, lighter tones), whereas softer bottom types such as fine sediment return weaker intensities (low backscatter, darker tones).
Moreover, the chemical bonds of Ni C and Ni N are still observed despite weaker intensities.
We also observed two additional bands with much weaker intensities in Western blot analyses (Fig. 6C).
Blanca developed as a tropical depression on Sunday evening and had maintained a relatively weak intensity into Wednesday.
Tussock grasses recorded the weakest intensity of facilitative interactions with recently emerged seedlings, switching to competitive interactions as degradation increased.
