The phrase "aged matrix" is correct and usable in written English.
It can be used in contexts related to materials, processes, or data that have undergone a period of aging or maturation.
Example: "The aged matrix of the cheese contributed to its rich flavor and texture."
Alternatives: "matured matrix" or "old matrix."
Specifically, we evaluated the validity and performance of IDM for marine sediments from a Superfund site contaminated with DDT and PCBs from many decades ago, and demonstrated the predictability of IDM for contaminant bioavailability in extensively aged matrices.
X-ray Energy Dispersive Spectroscopy analysis showed no chemical degradation incidents on the fibre reinforcement surfaces and infrared spectroscopy revealed superficial chemical alteration in the aging matrix.
A comparison with separate static fatigue experiments using unimpregnated fibre bundles demonstrated that the specific physico-chemical environment encountered by the glass fibres within the aged epoxy matrix can induce significant changes in the subcritical crack propagation rates, as compared to stress corrosion cracking data collected in humid air.
In addition, these tools are flexibly integrated with the learning activities under the consideration of the students' cognitive levels based on Starkey's Digital Learning Age Matrix (Starky 2011).
This dualism may have been the product of the Christology that Applewhite learned as a young man; Lewis writes that the group's teachings had "Christian elements [that] were basically grafted on to a New Age matrix".
We compared the sampled recruiter-recruit age matrix with the participant-contact age matrix collected in the Netherlands during POLYMOD (Van de Kassteele J, Van Eijkeren J, Wallinga J: Efficient estimation of age-specific social contact rates between men and women, in preparation) [ 9].
We and other investigators have found that there are common mediators of these processes in human OA cartilage and from early through late stages of OA in mouse models, including the surgical models (good matrix with abnormal loading) and the genetic models during aging (bad matrix with normal loading).
The results illustrated that the aging of SBS modified asphalt was formed by both aging of matrix asphalt and aging of SBS modifier.
Tensile properties remained practically unaffected by aging whereas matrix dominated shear properties revealed an initial drop which was recovered to a substantial degree after further hygrothermal aging.
Several factors identified include genetics, aging, extracellular matrix modifications, imbalance between inhibitors and promineralizing factors, dysregulation of PPi and Pi metabolism, and chondrocyte phenotype alterations such as hypertrophic differentiation and apoptosis [ 25, 26].
