Cho N, Shi J, Murphy R, Riley J, Rogers S, Richards J
Soft Matter . 2023 Sep; 19(48):9379-9388. PMID: 37681714
Probing the transient microstructure of soft matter far from equilibrium is an ongoing challenge to understanding material processing. In this work, we investigate inverse worm-like micelles undergoing large amplitude oscillatory...

Cho N, Riley J, Richards J
J Phys Chem B . 2021 Sep; 125(39):11067-11077. PMID: 34550697
The rheology of wormlike micelle (WLM) solutions is tunable by engineering the micellar structure and topology. While much is known about how microscopic properties influence the rheological characteristics, questions remain...

Riley J, Richards J, Wagner N, Butler P
Soft Matter . 2018 May; 14(26):5344-5355. PMID: 29808890
Topology and branching play an important but poorly understood role in controlling the mechanical and flow properties of worm-like micelles (WLMs). To address the challenge of characterizing branching during flow...

Riley J, Matyjaszewski K, Tilton R
J Colloid Interface Sci . 2018 May; 526:114-123. PMID: 29723792
Hypothesis: Adsorption of polyelectrolyte brush-grafted nanoparticles (BGNPs) produces a heterogeneous interface with sub-monolayer surface coverage resulting from lateral electrostatic repulsions that limit packing. As a result, the interaction forces between...

Nordmark B, Bechtel T, Riley J, Velegol D, Velegol S, Przybycien T, et al.
Langmuir . 2018 Mar; 34(16):4852-4860. PMID: 29566490
Motivated by the proposed use of cationic protein-modified sand for water filtration in developing nations, this study concerns the adsorption of Moringa oleifera seed proteins to silica surfaces. These proteins...

Richards J, Hipp J, Riley J, Wagner N, Butler P
Langmuir . 2017 Oct; 33(43):12260-12266. PMID: 28968116
High-structured carbon fillers are ubiquitous as the conductive additive comprising suspension-based electrochemical energy storage technologies. Carbon black networks provide the necessary electrical conductivity as well as mechanical percolation in the...

Riley J, Tilton R
Langmuir . 2016 Oct; 32(44):11440-11447. PMID: 27734683
This work investigates surface forces that result from adsorbed layers of silica nanoparticles with grafted pH-responsive, cationic poly(2-(dimethylamino)ethyl methacrylate) brushes (SiO-g-PDMAEMA) and how adhesive bridging forces can be suppressed and...

Riley J, An J, Tilton R
Langmuir . 2015 Dec; 31(51):13680-9. PMID: 26649483
The interactions between silica nanoparticles grafted with a brush of cationic poly(2-(dimethylamino) ethyl methacrylate) (SiO2-g-PDMAEMA) and anionic surfactant sodium dodecyl sulfate (SDS) is investigated by dynamic light scattering, electrophoretic mobility,...

Klosterman L, Riley J, Bettinger C
Langmuir . 2015 Mar; 31(11):3451-8. PMID: 25741573
Dopamine-melanin (DM or "polydopamine") can be deposited on virtually any substrate from solution through autoxidation of dopamine. The versatility of this process has allowed surface-mediated assembly of DM for a...

Langmuir . 2014 Mar; 30(14):4056-65. PMID: 24660872
Adsorption of 20 nm diameter silica nanoparticles grafted with a high density brush of the weak polymeric base poly(2-(dimethylamino)ethyl methacrylate) (SiO2-g-PDMAEMA) to the silica/aqueous interface was investigated using ellipsometry and...
