Dynamics of wire frame glasses in two dimensions Open

David A. King · 2023

The dynamics of wire frame particles in concentrated suspension are studied by means of a 2D model and compared to those of rod-like particles. The wire frames have bent or branched structures constructed from infinitely thin rigid rods. I…

Differential response of chlorophyll-a concentrations to explosive volcanism in the western South Pacific Open

Joo‐Eun Yoon, David A. King, Jack Longman, Shane J. Cronin · 2023

When it is deposited in the ocean, volcanic ash has the potential to release iron and other nutrients into surface water to stimulate ocean productivity. In the western South Pacific Ocean (SPO), one of the most important volcanic ash depo…

Towards New Liquid Crystal Phases of DNA mesogens Open

Kit Gallagher, Jiaming Yu, David A. King, Ren Liu, Erika Eiser · 2023

Short, partially complementary, single-stranded (ss)DNA strands can form nanostructures with a wide variety of shapes and mechanical properties. It is well known that semiflexible, linear dsDNA can undergo an isotropic to nematic (IN) phas…

Bioactivation of particles Open

Fabien Pinaud, David A. King, Shimon Weiss · 2023

Particles are bioactivated by attaching bioactivation peptides to the particle surface. The bioactivation peptides are peptide-based compounds that impart one or more biologically important functions to the particles. Each bioactivation pe…

What Promotes Smectic Order: Applying Mean Field Theory to the Ends Open

David A. King, Randall D. Kamien · 2022

Not every particle that forms a nematic liquid crystal makes a smectic. The particle tip is critical for this behaviour. Ellipsoids do not make a smectic, but sphero-cylinders do. Similarly, only those N-CB alkylcyanobiphenyls with suffici…

A field theory approach to the statistical kinematic dynamo Open

Daria Holdenried-Chernoff, David A. King, B. A. Buffett · 2022

Variations in the geomagnetic field occur on a vast range of time scales, from milliseconds to millions of years. The advent of satellite measurements has allowed for detailed studies of the short timescale geomagnetic field behaviour, but…
