The unit-cell of the acoustic metamaterial consists of external mass, spring and internal mass.
ES tuning mix (Agilent Technologies, Palo Alto, CA, USA; reorder no. G2421A) was used for external mass calibration.
Sodium formate solution (0.1 M) in 50% (v/v) isopropanol was used for external mass calibration and was injected into the ESI source at the beginning of each analysis, using a switch valve and a segmented acquisition method.
An accuracy of ≤2 ppm is achieved by internal mass calibration using lock mass functionality; using external mass calibration, an accuracy of ≤3 ppm is routinely obtained.
The results demonstrate that the leaf-inspired microfluidic network can not only effectively transport fluid without the use of external pumps, but also facilitate rapid mass diffusion within bulk hydrogel chips.
An analytical solution is presented and experimental results and theoretical data are in good agreement, for a wide range of operating conditions, using a single external mass transfer coefficient and a single effective solid diffusivity.
The decision to restrict the use of external consultants has increased the workload for the Civil Service.
To ensure the mass accuracy, all spectra were calibrated using external mass standards: hirudin BHVK (6,964 Da), equine myoglobin (cardiac, 16,951.5 Da), and bovine carbonic anhydrase RBC (29,023.7 Da).
To characterize the physical parameters of oxidant external mass transfer to the coal grains and pyrite, we used the term "mass transfer coefficient"; the intensity of fluidized bed – "fluidized bed porosity".
Several size fractions of catalyst particles were also used to study the external mass transfer resistance and the internal resistance to pore diffusion and chemical reaction.
