The phrase "at its focal point" is correct and usable in written English.
It can be used to indicate the central or most important aspect of a discussion, analysis, or situation.
Example: "The debate on climate change is at its focal point, with scientists urging immediate action."
Alternatives: "at its center" or "at the heart of".
These monomers contain either a benzo-15-crown-5 derivative, which is incorporated via the esterification of 4′-hydroxymethyl-1,4,7,10,13-pentaoxabenzocyclopentadecane or a podant group, which is incorporated via the monoesterification of tetraethylene glycol at its focal point, and both bear polymerizable groups on their periphery.
We describe a process for transferring octadecylamine-stabilized CdSe/ZnS core shell semiconductor nanocrystals (ODA-QDs) from chloroform into water through a ligand exchange process with a dendron ligand which has two primary amine anchoring groups at its focal point and hydroxyl groups as its terminal groups.
Their doctrine is an inconsistent patchwork of arbitrary statistics, theories, and ideologies often conflicting all matted together to create a disembodied political ideology with misogyny at its focal point.
The laser-induced coagulation was performed in a repetitive manner with the hand-piece, of the irradiation delivery system, being held perpendicular to the skin with the lesion at its focal point.
The result is a round piece of glass that is thick in the middle, where the straight-line path crosses, and tapers off towards the edge, where the less direct routes do—in other words, a focusing lens, with its focal point at B.Dr Capasso's lens, described in Nano Letters, also slows photons down.
By establishing a baseline picture of how the worst epidemiologic disaster of the modern era unfolded at its global focal point, it is hoped that this study will prompt future research that delves into the complex factors that created and shaped it spatially and temporally [ 8, 57, 58].
The results significantly advance our knowledge of this devastating pandemic at its global focal point.
Although the 3-blade structure is clearly visible at locations away from the focal point, it loses its fine feature in its intensity pattern at the focal point, where the intensity gradient is needed for forming the trap.
Its silhouette is subtly tapered, he says, so its facades converge at an imaginary focal point 10 times its height – a learned nod to Edwin Lutyens Cenotaphh memorial in Whitehall, whose planes meet at a projected spot 1,000ft in the air.
Depending on the absorption mechanism involved, we get a Lorentzian or inverted Lorentzian with its maximum or minimum at the focal point, z = 0 where the fluence is a maximum.
"It's sort of like using a magnifying glass out in the sun," he said, where a leaf can be burned only if it is at the focal point of the sunlight.
