The phrase "a substantially lower temperature" is correct and usable in written English.
It can be used when comparing temperatures, particularly in scientific or technical contexts.
Example: "The experiment was conducted at a substantially lower temperature than the previous trials, resulting in different chemical reactions."
Alternatives: "a significantly lower temperature" or "a markedly lower temperature."
The maxima in the enthalpy recovery peaks are at substantially lower temperature, as much as 17 °C, in the gradient copolymers as compared to random copolymers of equal overall composition.
In comparison, flash sintering occurs at a substantially lower onset temperature of ∼550 °C in ZnO powder specimens, indicating the important roles of surfaces and/or grain boundaries.
Although F element genes are larger and have more coding exons than euchromatic genes, the metagene has a substantially lower melting temperature, presumably because of the high AT content within introns and the low codon bias.
Individuals from high-altitude sites in Scotland experience substantially lower temperatures than their low-altitude counterparts, with an average mean annual temperature reduction of 4.5°C at high- compared to low-altitude breeding sites [ 40].
Reduction in hydrogen proceeds at substantially lower temperatures.
Monounsaturated and polyunsaturated molecules melt at substantially lower temperatures than do their saturated analogs, with the lowest melting temperatures occurring when the carbon-carbon double bonds are located near the centre of the hydrocarbon chain, as they are in most biological molecules.
In this work, a recently discovered method, herein referred to as chemical deSOx, was found to be effective for removal of sulfur and for recovery of NOx conversion at substantially lower temperatures.
During pretreatment in a sulfiding atmosphere (such as H2S/H2) dispersed islands of MoS2 segregate from the precursor and provide a pathway for H2 dissociation that allows reduction of the phosphite precursor to nickel phosphide at substantially lower temperatures than in the absence of MoS2.
However, unlike its mammalian and avian counterparts [6], [7], [17], the frog channel showed little or no basal activity at room temperature (25°C) and required substantially lower temperatures for activation at physiological membrane potentials (Fig. 3B).
