Correction: Tap density equations of granular powders based on the rate process theory and the free volume concept

Abstract

Correction for ‘Tap density equations of granular powders based on the rate process theory and the free volume concept’ by Tian Hao et al., Soft Matter, 2015, DOI: 10.1039/c4sm02472a.

The authors regret the following errors in eqns (23), (24) and (26). The corrected equations are shown below.

The section on page 4

The energy flowing from the shaker to the powder³⁶ is:

where M_g is the weight of powder. The total energy flowing to the powder after a series of tapping processes with the tapping number, n, may be expressed as:

should be corrected to

The energy flowing rate from the shaker to the powder³⁶ is:

where Mg is the weight of powder. The total energy flowing to the powder after a series of tapping processes with the tapping number, n, may be expressed as:

E = nE(t)t = nMgL₀ (24)

where t is the time spent for one tap.

The sentence on page 5

Substituting eqn (24) into eqn (25) yields:

where τ is a constant of τ = πRT/(MgL₀ω)

should be corrected to

Substituting eqn (24) into eqn (25) yields:

where τ is a constant of τ = RT/(MgL₀).

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
