Exploring the experimental foundation with rupture and delayed rupture
Asal Y Siavoshani, Cheng Liang, Ming-Chi Wang +4
We carry out uniaxial continuous and step stretching of various crosslinked polymer networks to demonstrate how characteristics of rupture (from continuous stretching) and delayed…
Liquid crystalline structures formed by sphere-rod amphiphilic molecules in solvents
Nilanthi P. Haputhanthrige, Yifan Zhou, Jingfan Wei +3
Self-assembly of amphiphilic molecules is an important phenomenon attracting a broad range of research. In this work, we study the self-assembly of KTOF4 sphere-rod amphiphilic mol…
Modeling Structural Colors from Disordered One-Component Colloidal Nanoparticle-based Supraballs using Combined Experimental and Simulation Techniques
Anvay Patil, Christian M. Heil, Bram Vanthournout +8
Bright, saturated structural colors in birds have inspired synthesis of self-assembled, disordered arrays of assembled nanoparticles with varied particle spacings and refractive in…
Fracture mechanical behavior of polymers: 1. Amorphous glassy state
Travis Smith, Chaitanya Gupta, Caleb Carr +1
Theoretical analyses and experiments have been carried out to investigate fracture behavior of glassy polymers. Our birefringence measurements quantify the local stress buildup at…
Micromechanical origin of plasticity and hysteresis in nest-like packings
Yashraj Bhosale, Nicholas Weiner, Alex Butler +3
Disordered packings of unbonded, semiflexible fibers represent a class of materials spanning contexts and scales. From twig-based bird nests to unwoven textiles, bulk mechanics of…
Dependence of Adhesive Friction on Surface Roughness and Elastic Modulus
Daniel Maksuta, Siddhesh Dalvi, Abhijeet Gujrati +3
When adhesive elastomeric materials slide over hard rough surfaces at low velocities, there are two primary dissipative mechanisms that control how friction changes with sliding ve…
Adhesive forces inhibit underwater contact formation for a soft-hard collision
Mengyue Sun1, Nityanshu Kumar1, Ali Dhinojwala +1
Thermodynamics tells us to expect underwater contact between two hydrophobic surfaces to result in stronger adhesion compared to two hydrophilic surfaces. However, presence of wate…
Ion-dependent DNA Configuration in Bacteriophage Capsids
Pei Liu, Javier Arsuaga, M. Carme Calderer +3
Bacteriophages densely pack their long dsDNA genome inside a protein capsid. The conformation of the viral genome inside the capsid is consistent with a hexagonal liquid crystallin…
Perspective: Mechanics of randomly packed filaments -- the `bird nest' as meta-material
Nicholas Weiner, Yashraj Bhosale, Mattia Gazzola +1
Systems of randomly packed, macroscopic elements, from jammed spherical grains to tangled long filaments, represent a broad class of disordered meta-materials with a wide range of…
Linking energy loss in soft adhesion to surface roughness
Siddhesh Dalvi, Abhijeet Gujrati, Subarna R. Khanal +3
A mechanistic understanding of adhesion in soft materials is critical in the fields of transportation (tires, gaskets, seals), biomaterials, micro-contact printing, and soft roboti…
Fragmentation of shells: An analogy with the crack formation in tree bark
Chuang-Shi Shen, Chao Zhang, Xiaosheng Gao +1
How does a shell explode into a series of fragments upon impact? The well accepted explanation is Mott's theory, which considers the fragmentation of shells as a random process con…
A Novel Landau-de Gennes Model with Quartic Elastic Terms
Dmitry Golovaty, Michael Novack, Peter Sternberg
Within the framework of the generalized Landau-de Gennes theory, we identify a -tensor-based energy that reduces to the four-constant Oseen-Frank energy when it is considered ov…
Comment on "Edge-Induced Shear Banding in Entangled Polymeric Fluids" [arXiv: 1801.08798]
Yangyang Wang, Shi-Qing Wang
Based on numerical modeling with the diffusive Giesekus constitutive equation, a recent Letter [Phys. Rev. Lett. 120, 138002 (2018), arXiv:1801.08798] claimed that the experimental…
Generalized model for the diffusion of solvents in glassy polymers: From Fickian to super Case II
Jiayuan Miao, Mesfin Tsige, Philip L. Taylor
The diffusion of small solvent molecules in glassy polymers may take on a variety of different forms. Fickian, anomalous, Case II, and super Case II diffusion have all been observe…
Fingerprinting molecular relaxation in deformed polymers
Zhe Wang, Christopher N. Lam, Wei-Ren Chen +8
The flow and deformation of macromolecules is ubiquitous in nature and industry, and an understanding of this phenomenon at both macroscopic and microscopic length scales is of fun…
Hexadecapolar colloids
Bohdan Senyuk, Owen Puls, Oleh M. Tovkach +2
Outermost occupied electron shells of chemical elements can have symmetries resembling that of monopoles, dipoles, quadrupoles and octupoles corresponding to filled s-, p-, d- and…
Q-tensor model for electrokinetics in nematic liquid crystals
Oleh M. Tovkach, Christopher Conklin, M. Carme Calderer +4
We use a variational principle to derive a mathematical model for a nematic electrolyte in which the liquid crystalline component is described in terms of a second-rank order tenso…
Electro-osmosis in nematic liquid crystals
O. M. Tovkach, M. Carme Calderer, Dmitry Golovaty +2
We derive a mathematical model of a nematic electrolyte based on a variational formulation of nematodynamics. Extending our previous work, we consider a general setup which incorpo…
A non-traditional view on the modeling of nematic disclination dynamics
Chiqun Zhang, Xiaohan Zhang, Amit Acharya +2
Nonsingular disclination dynamics in a uniaxial nematic liquid crystal is modeled within a mathematical framework where the kinematics is a direct extension of the classical way of…
Transitions of tethered chain molecules under tension
Jutta Luettmer-Strathmann, Kurt Binder
An applied tension force changes the equilibrium conformations of a polymer chain tethered to a planar substrate and thus affects the adsorption transition as well as the coil-glob…
Compressible or incompressible blend of interacting monodisperse star and linear polymers near a surface
Richard Batman, P. D. Gujrati
We consider a lattice model of a mixture of repulsive, attractive, or neutral monodisperse star (species A) and linear (species B) polymers with a third monomeric species C, which…
Transitions of tethered polymer chains: A simulation study with the bond fluctuation lattice model
Jutta Luettmer-Strathmann, Federica Rampf, Wolfgang Paul +1
A polymer chain tethered to a surface may be compact or extended, adsorbed or desorbed, depending on interactions with the surface and the surrounding solvent. This leads to a rich…
Solubility in Compressible Polymers: Beyond the Regular Solution Theory
Albert A. Smith, P. D. Gujrati
The age-old idea of "like dissolves like" requires a notion of "likeness" that is hard to quantify for polymers. We revisit the concepts of pure component cohesive energy density $…
