Sentence examples for chemical composition needs from inspiring English sources

The catalytic effect on PM emissions, especially on chemical composition, needs further investigations.

Once the hardware and the physical parameters of the sample environment have been optimized, the sample chemical composition needs to be carefully adjusted to maximize the C polarization of metabolic substrates.

For the epitaxial growth of ionic oxides, when all film components are supplied simultaneously, the oscillation period corresponds to the minimum unit of the chemical composition needed to ensure charge neutrality21,22,23.

The latency phase is 2 h, resulting from the use of an organic complex chemical composition, which needs the intervention of bacteria in the first three stages of anaerobic digestion (hydrolysis, acidogenesis and acetogenesis) to degrade and convert the substrates available for the methanogenic stage (acetate, CO2 and H2).

Among the mentioned methods, MCR can provide a quantitative determination of the chemical composition but needs an initial guess of the spectra and is thus not unsupervised.

All the results indicated that the anti-corrosive performance was not the only index, the microstructure and chemical composition also needed to be considered in the development of a new generation pre-treatment layer.

Since the variation in the native extracellular matrix (ECM) between in vivo and 2D in vitro conditions is one of the key reasons for such discrepancies, thus the utilization of substrate that likely mimics ECM characteristics (topography, stiffness, and chemical composition) is needed to overcome such problem.

Although APXS and ChemCam will tell you which chemical elements are present, they don't tell you how precisely those atoms are arranged into the crystalline structures that make up the rock, and both this mineralogy and the chemical composition are ideally needed to assign a rock name.
