The phrase "attributed to a heterogeneous" is grammatically correct and can be used in written English.
It can be used in contexts where you are discussing something that is ascribed or assigned to a diverse or varied group or category.
Example: "The findings of the study were attributed to a heterogeneous population, which included individuals from various backgrounds and experiences."
Alternatives: "assigned to a diverse" or "ascribed to a varied".
Variability in results was attributed to a highly heterogeneous horizon consisting of layered media of varying physical properties.
In previous studies, human and ape TAS2Rs were also found to be evolving at an overall rate near 1 (Wang et al. 2004; Fischer et al. 2005), which was attributed to a composite of heterogeneous rates of evolution across the protein and not necessarily due to uniform lack of functional constraint across the entire protein.
On the low frequency side of the α process an additional process α′ was observed that was attributed to a local ionic fluctuation in a heterogeneous medium.
Indeed, it is unlikely that the root cause of a so much heterogeneous disease could be attributed to a single gene.
The high resistance to fatigue crack growth cannot only be attributed to an increase in hardness, but is also associated with heterogeneous hardness distribution.
The higher performance with our nanocomposite NiO-YSZ anode is primarily attributed to its heterogeneous nanograin structure, thus leading to a significant increase in triple phase boundary densities.
In our reasoning, we demonstrated that the hetero interface, which were produced by cation exchanges that caused a lower lattice symmetric structure, attributed to the heterogeneous hexagonal shell growth.
Comparing the kinetic models of deactivation for two catalysts with different acidity strength distributions, the need for a kinetic model of selective deactivation is attributed to the heterogeneous nature of the acidic structure of the catalyst.
The two-stage degradation of melamine-acrylic structure is attributed to the heterogeneous microstructure of the coating, and the enhanced degradation is explained by a mechanism based on hydrolysis-generated formaldehyde molecules, which act as chromophores to absorb UV light and accelerate photo-oxidation.
The ablation of the composite was attributed to the heterogeneous reactions between carbon and oxidizing species.
