Alhazmi N, Pineda E, Rawle J, Howse J, Dunbar A
ACS Appl Energy Mater . 2020 Sep; 3(7):6155-6164. PMID: 32905480
wide-angle X-ray scattering (WAXS) has been measured during the spin coating process used to make the precursor films required for the formation of thin films of perovskite. A customized hollow...

Topham P, Howse J, Fernyhough C, Ryan A
Soft Matter . 2020 Sep; 3(12):1506-1512. PMID: 32900105
Poly(styrene)--poly(2-vinyl pyridine)--poly(styrene) (PS--P2VP--PS) triblock copolymers were synthesised by anionic polymerisation. Thick films were cast from solution and their structure analysed by small angle X-ray scattering (SAXS). Longer annealing times led...

Saez-Martinez V, Mann A, Lydon F, Molock F, Layton S, Toolan D, et al.
J Biomed Mater Res B Appl Biomater . 2020 Jul; 109(1):137-148. PMID: 32710466
The importance of the microstzructure of silicone hydrogels is widely appreciated but is poorly understood and minimally investigated. To ensure comfort and eye health, these materials must simultaneously exhibit both...

Geoghegan M, Ruiz-Perez L, Dang C, Parnell A, Martin S, Howse J, et al.
Soft Matter . 2020 Jul; 2(12):1076-1080. PMID: 32680210
We have used neutron reflectometry to characterize the swelling behaviour of brushes of poly[2-(diethyl amino)ethyl methacrylate], a polybase, as a function of pH. The brushes, synthesized by the "" method...

Bernardo G, Washington A, Zhang Y, King S, Toolan D, Weir M, et al.
R Soc Open Sci . 2019 Mar; 5(9):180937. PMID: 30839721
1,8-Diiodooctane (DIO) is an additive used in the processing of organic photovoltaics and has previously been reported, on the basis of small-angle X-ray scattering (SAXS) measurements, to deflocculate nano-aggregates of...

Isakova A, Karuthedath S, Arnold T, Howse J, Topham P, Toolan D, et al.
Nanoscale . 2018 Jun; 10(23):10934-10944. PMID: 29850749
In bulk heterojunction donor-acceptor (D-A) blends, high photovoltaic yields require charge carrier separation to outcompete geminate recombination. Recently, evidence for long-range electron transfer mechanisms has been presented, avoiding strongly-bound interfacial...

Archer R, Parnell A, Campbell A, Howse J, Ebbens S
Adv Sci (Weinh) . 2018 Apr; 5(2):1700528. PMID: 29619303
The field of active colloids is attracting significant interest to both enable applications and allow investigations of new collective colloidal phenomena. One convenient active colloidal system that has been much...

Toolan D, Adlington K, Isakova A, Kalamiotis A, Mokarian-Tabari P, Dimitrakis G, et al.
Phys Chem Chem Phys . 2017 Jul; 19(31):20412-20419. PMID: 28731101
Microwave annealing has emerged as an alternative to traditional thermal annealing approaches for optimising block copolymer self-assembly. A novel sample environment enabling small angle X-ray scattering to be performed in...

J Colloid Interface Sci . 2016 Nov; 487:465-474. PMID: 27814558
A new approach is described herein, where neutron reflectivity measurements that probe changes in the density profile of thin films as they absorb material from the gas phase have been...
