Active metamaterials for realizing odd mass density PNAS
2023年3月29日 The odd mass density contributes to the wave anisotropy in the energy-unbroken phase and directional wave energy gain in the energy-broken phase. We also numerically illustrate and experimentally demonstrate the two-dimensional wave propagation phenomena that arise from the odd mass in active solids.

Changing Bed Bulk Density and other Process Conditions
The composition of Blend B given in Table 1 can be considered to be the base case. To reduce bed bulk density a very porous ore (VPO) was introduced into this blend. As the chemical composition of VPO is very similar to the low-alumina pisolite ore in the blend (), directly substituting VPO for this pisolite ore gave no significant changes in sinter

Specific gravity bulk density - alsglobal
Bulk density. This variable is characterised by determining the volume of water that is displaced by a sample when it is submerged. The weight of the sample is then divided by the volume of water displaced to produce a density with a unit of g/cm 3.Bulk density can be determined for raw samples, those coated in paraffin, fragmented samples, and samples
