Abstract

Correction for ‘Surface induced smectic order in ionic liquids – an X-ray reflectivity study of [C22C1im]+[NTf2]−’ by Julian Mars et al., Phys. Chem. Chem. Phys., 2017, 19, 26651–26661.

The following errata were found in the published article. All the data analysis and figures in the original article are correct. Likewise, the results and conclusions remain unaffected.

Model profiles

The first sentence of the second paragraph on page 26654 should read:

“The oscillatory function with periodicity d is expanded in a series

 
image file: c8cp91851a-t1.tif(6)
with the total number of electrons per [C22C1im]+[NTf2]− molecule ZIL = 358 and per 37 CH2 hydrocarbon equivalents ZHC = 37.8, respectively.55”

Surface thermodynamics

The sentence containing eqn (10) on page 26654 should read:

“For complete wetting (Δγ < 0)

 
image file: c8cp91851a-t2.tif(10a)
 
image file: c8cp91851a-t3.tif(10b)

is found.”

Surface structure

In Table 1 on page 26657 the decimal point of a single entry is shifted. The entry should read Bb (115 °C) = 1.93.

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