How polymer additives reduce the pour point of hydrocarbon solvents containing wax crystals (2015)
Journal Article
Binks, B. P., Fletcher, P. D. I., Roberts, N. A., Dunkerley, J., Greenfield, H., Mastrangelo, A., & Trickett, K. (2015). How polymer additives reduce the pour point of hydrocarbon solvents containing wax crystals. Physical chemistry chemical physics : PCCP, 17(6), 4107-4117. https://doi.org/10.1039/c4cp04329d

We have investigated how four different pour point depressant (PPD) polymers affect the pour point transition in mixtures of a single pure wax in a solvent. We used either n-eicosane (C20), CH3(CH2)18CH3, n-tetracosane (C24), CH3(CH2)22CH3 or n-hexat...

Do the short helices exist in the nematic TB phase? (2015)
Journal Article
Górecka, E., Salamończyk, M., Zep, A., Pociecha, D., Welch, C., Ahmed, Z., & Mehl, G. H. (2015). Do the short helices exist in the nematic TB phase?. Liquid crystals, 42(1), 1-7. https://doi.org/10.1080/02678292.2014.984646

Dimeric compounds forming twist-bend nematic, Ntb, phase show unusual optical textures related to the formation of arrays of focal conic defects (FCDs). Some of the focal conics exhibit submicron internal structure with 8 nm periodicity, which is ver... Read More about Do the short helices exist in the nematic TB phase?.

Positive and negative allosteric effects of thiacalix[4]arene-based receptors having urea and crown-ether moieties (2015)
Journal Article
Tomiyasu, H., Zhao, J.-L., Ni, X.-L., Zeng, X., Elsegood, M. R. J., Jones, B., Redshaw, C., Teat, S. J., & Yamato, T. (2015). Positive and negative allosteric effects of thiacalix[4]arene-based receptors having urea and crown-ether moieties. RSC advances, 5(19), 14747-14755. https://doi.org/10.1039/c4ra15905e

Heteroditopic receptors (4ₐ₋ₑ) based on a thiacalix[4]arene in the 1,3-alternate conformation, which have two urea moieties linking various phenyl groups substituted with either electron-donating or -withdrawing groups at their m-, or p-positions wit...

Mono- and tetra-nuclear copper complexes bearing bis(imino)phenoxide derived ligands: catalytic evaluation for benzene oxidation and ROP of ε-caprolactone (2015)
Journal Article
Wang, X., Zhao, K.-Q., Elsegood, M. R. J., Prior, T. J., Liu, X., Wu, L., Sanz, S., Brechin, E. K., & Redshaw, C. (2015). Mono- and tetra-nuclear copper complexes bearing bis(imino)phenoxide derived ligands: catalytic evaluation for benzene oxidation and ROP of ε-caprolactone. RSC advances, 5(71), 57414-57424. https://doi.org/10.1039/c5ra08696e

Complexes of the type [Cu(L)₂] (1) and [Cu₄L₂(μ₄-O)(OAc)₄] (2) have been obtained from the reaction of the phenoxydiimine 1,3-(2,6-R²₂C₆H₃N=CH)₂-5-R¹ C₆H₂OH-2 (LH) (where R¹ = Me, tBu, Cl; R² = Me, iPr) with copper(II) acetate [Cu(OAc)₂]; changing th...

A fibre forming smectic twist-bent liquid crystalline phase (2015)
Journal Article
Tamba, M. G., Salili, S. M., Zhang, C., Jákli, A., Mehl, G. H., Stannarius, R., & Eremin, A. (2015). A fibre forming smectic twist-bent liquid crystalline phase. RSC advances, 5(15), 11207-11211. https://doi.org/10.1039/c4ra14669g

We demonstrate the nanostructure and filament formation of a novel liquid crystal phase of a dimeric mesogen below the twist–bend nematic phase. The new fibre-forming phase is distinguished by a short-correlated smectic order combined with an additio... Read More about A fibre forming smectic twist-bent liquid crystalline phase.
