Ataie S, Malmir A, Scott S, Goettel J, Clemens S, Morrison D, et al.
Angew Chem Int Ed Engl . 2024 Oct; 63(49):e202410154. PMID: 39473397
While functionalized polyethylenes (PEs) exhibit valuable characteristics, the constraints of existing synthetic approaches limit the variety of readily incorporated functionality. New methods to generate functionalized PEs are required to afford...

Jung H, Goonesinghe C, Zhang Z, Chang J, Nyamayaro K, Baalbaki H, et al.
ACS Macro Lett . 2024 Feb; :266-272. PMID: 38335927
We report the selective double ring-opening polymerization of presequenced spiroorthoester monomers to form high-molecular-weight (≈90 kDa) poly(ether--ester)s with a simple cationic alkyl gallium catalyst. The selective formation of double ring-opened...

Carbohydr Polym . 2023 Jan; 302:120378. PMID: 36604056
A systematic rheological study on the influence of valency of different counterions on the properties of CNC hydrogels was carried out. Rheo-polarized microscopy was used to prove that preshear of...

Lewis L, Hatzikiriakos S, Hamad W, MacLachlan M
ACS Macro Lett . 2022 May; 8(5):486-491. PMID: 35619375
Gels are attractive for applications in drug delivery, tissue engineering, and 3D printing. Here, physical colloidal gels were prepared by freeze-thaw (FT) cycling of cellulose nanocrystal (CNC) suspensions. The aggregation...

Wright T, Karis D, Millik S, Tomkovic T, Hatzikiriakos S, Nelson A, et al.
ACS Appl Mater Interfaces . 2021 May; 13(19):22195-22203. PMID: 33944560
Mechanically robust bulk antimicrobial polymers are one way to address disease transmission via contaminated surfaces. Here, we demonstrate the visible light photo-oxidative cross-linking of amine-containing PDMS using a single-component, solvent-free...

Mitsoulis E, Hatzikiriakos S
Polymers (Basel) . 2021 Feb; 13(4). PMID: 33557292
Rheological properties related to the extrusion of polyolefins are the shear viscosity, the elongational viscosity, the slip velocity and their temperature- and pressure-dependencies. These properties are measured in the rheology...

Langmuir . 2019 Dec; 36(1):293-301. PMID: 31845815
The gelation of cellulose nanocrystal (CNC) suspensions is explored in the presence of two ionic surfactants, namely, sodium dodecyl sulfate (SDS) with a negatively charged head and cetyltrimethylammonium bromide (CTAB)...
