The phrase "a much higher mass" is correct and usable in written English.
It can be used when comparing the mass of one object or substance to another, indicating that the first has significantly more mass.
Example: "The new planet discovered in our solar system has a much higher mass than Earth, which could affect its gravitational pull."
Alternatives: "a significantly greater mass" or "a considerably larger mass".
However, for large-scale device fabrication a much higher mass of active material is recommended.
The porous carbon membrane/SMFs composites as high efficiency adsorbents can offer a much higher mass transfer efficiency, contacting efficiency as well as adsorption rate.
Among all these morphologies, the flower- and nanosheet-like Pt particles on the ITO have a much higher mass specific activity (MA) for the methanol oxidation, and the Pt particles with prickly surface followed while the smooth spherical Pt particles have the lowest MA.
The intact cells in the kernels of larger grains have a much higher mass transfer resistance.
The much greater challenge lay in any other part with larger dimensions and a much higher mass than the small sized sensors.
However, a much higher mass loss in step three (and, as a consequence, a much smaller residue at 1000°C) is observed in the samples obtained from the Ancient Roman frescoes compared with those of the Renaissance frescoes.
Much higher mass loading of manganese oxide is successfully maintained (∼2.4 mg cm−2) through this new type of nanoarchitecture.
The much higher mass of the black hole in IC 2497 results in much slower changes over many thousands of years.
The resultant catalyst (Pt/Ti0.8Co0.2O2 NTAs) exhibited much higher mass activity for oxygen reduction reaction (ORR) compared with the commercial Pt/C catalyst, and it also possesses excellent structure stability.
Similarly, the newly-prepared monodispersed PdCu nanospheres also exhibited much higher mass activity and durability than single-phase Pd and commercial Pd/C towards ethylene glycol electrooxidation in the alkaline media.
However, the IrO2 has a lower onset potential, lower η of 0.394 V at 10 mA cm−2disk (which is a metric related to solar fuel synthesis31; Fig. 2a), lower Tafel slope (59 mV dec−1; Fig. 2b) and much higher mass activity (Fig. 2c) than those of the PBSCF-0.
