The phrase "a decrease in material" is correct and usable in written English.
It can be used when discussing a reduction in the quantity or quality of materials in various contexts, such as manufacturing, construction, or resource management.
Example: "The recent analysis showed a significant decrease in material used for production, leading to cost savings."
Alternatives: "a reduction in materials" or "a decline in material usage."
The apparent elastic modulus (Ea) was evaluated by performing quasi-static mechanical tests at various temperatures showing a decrease in material stiffness from 5 MPa at 25 °C to 2.2 MPa at 37 °C.
A general trend was observed of enhanced explosion likelihood and consequence severity with a decrease in material diameter, as well as enhanced consequence severity with admixture of a flammable gas to the combustion atmosphere.
One example where this manifests itself is in the well-known decrease in phase change temperature that accompanies a decrease in material dimensions [41].
The osteoporotic spine, however, suffers from both a decrease in material properties [ 10] that would require a large screw with deep threads and from the aforementioned risk of pedicular fracture [ 40, 43], which limits the size of the screw that can be utilized.
It also highlighted a decrease in the material required to make its products – the new iPad Air uses nearly one-third less material, by weight, than the original iPad.
A sensitivity study demonstrated that a decrease in the material cost for the containment system could significantly increase the breakeven shipping distance.
Despite the low cement content, results indicated a decrease in the material stiffness with fiber addition and an improvement in both pre- and post-cracking behavior.
Just as the Cultural Factor causes a decrease in the material benefits of trade, it also reduces economic growth.
Respirometry using modified cell culture microplates offers an increase in throughput and a decrease in biological material required for each assay.
Low flow static nanospray improves ionization efficiency, and in restricting analyte adsorption by restricting surface exposure, allows a decrease in the material scale of the sample being analyzed.
Although there is concern that the procedures we propose may result in a decrease in patient material available for publication, investigators have found that the great majority of patients continue to consent for publication of the image despite specific discussion of the potential availability of the image on the Internet.
