Two-dimensional pattern reverse Monte Carlo method is applied to investigate structural changes of silica particle filler in uniaxially elongated rubber. We calculated three-dimensional conformations of spherical silica particles using a series of two-dimensional patterns of structure factors during elongation. The structure factors we used are inter polated from experimentally observed structure factors for the elongation ratio epsilon = 0.0, 0.5, 1.0, and 1.5. To make a continuous motion of particles, we set the elongation ratio with small interval Delta epsilon = 0.001. It is found that the structural change of the particles seem to be reliable at least for small epsilon regions because spurious motions like the Brownian motions are not observed.

Mathematical Classification and Rheological Properties of Ring Catenane Structures

Katsumi Hagita, Takahiro Murashima, Naoki Sakata

Summary: The rheological properties of polycatenanes were studied through molecular dynamics simulations, revealing that the behavior of storage and loss moduli depends on the number of beads per catenane at low frequencies. The crossing numbers affect the moduli behaviors in the immediate frequency range, with smaller rings potentially exhibiting exceptionally large storage moduli at intermediate frequencies. Additionally, sol-gel transitions were observed for smaller ring sizes and/or larger crossing numbers in the simulation models.

Molecular dynamics studies of entropic elasticity of condensed lattice networks connected with uniform functionality f=4

Katsumi Hagita, Takahiro Murashima

Summary: In this study, the linear region of entropic elasticity was investigated using the simplest physical model, considering the fluctuation of strand length and the effect of network connectivity on elastic behavior. Molecular dynamics simulations were conducted on lattice networks to analyze stress-strain curves and the dependence of elastic modulus on fluctuation. The study revealed that the linear entropic region expands with increasing number of beads in a strand, and network topology plays a crucial role in the transition from entropic to energetic elasticity.

Ion Atmosphere of Wormlike Micelles Profiled by Contrast Variation Small-Angle Neutron Scattering

Guan-Rong Huang, Christopher N. Lam, Kunlun Hong, Yangyang Wang, Yuya Shinohara, Changwoo Do, Wei-Ren Chen

Summary: The structural studies of wormlike micelles have mainly focused on the conformational properties of surfactant aggregates, with little exploration on the diffuse ionic atmosphere. This report outlines a strategy using contrast variation small-angle neutron scattering for crucial structural studies. The analytical framework established can quantitatively describe counterion distribution in a mathematically tractable manner, and can be extended to facilitate studies of complex multicomponent systems using contrast variation neutron scattering.

Small angle scattering of diblock copolymers profiled by machine learning

Chi-Huan Tung, Shou-Yi Chang, Hsin-Lung Chen, Yangyang Wang, Kunlun Hong, Jan Michael Carrillo, Bobby G. Sumpter, Yuya Shinohara, Changwoo Do, Wei-Ren Chen

Summary: This study presents a machine learning strategy to quantitatively determine the conformation of AB-type diblock copolymers with excluded volume effects using small angle scattering. By establishing a correlation matrix and applying the Gaussian process, the relevant conformational characteristics of copolymers can be probabilistically inferred from their coherent scattering cross sections without model assumptions. This work is important for the quantitative structural analysis of copolymer solutions and the theoretical development of scattering functions.

Molecular Dynamics of Topological Barriers on the Crystallization Behavior of Ring Polyethylene Melts with Trefoil Knots

Katsumi Hagita, Takahiro Murashima, Naoki Sakata, Koya Shimokawa, Tetsuo Deguchi, Erica Uehara, Susumu Fujiwara

Summary: We investigated the topological barriers in ring polyethylene (PE) melts of trefoil knots and found that these barriers prevent crystallization due to self-entanglement. The topological barriers decrease with increasing polymer chain length (N) and the knotted segments are localized in the noncrystallized region. Our study provides insights into the effects of topology on crystallization in polymer melts.

Prediction of the Ground-State Electronic Structure from Core-Loss Spectra of Organic Molecules by Machine Learning

Po-Yen Chen, Kiyou Shibata, Katsumi Hagita, Tomohiro Miyata, Teruyasu Mizoguchi

Summary: A machine learning model was constructed to predict the partial density of states (PDOS) of the ground-state carbon s- and p-orbitals from C K-edge spectra. The model was also tested for extrapolation prediction of PDOS for larger molecules, and excluding tiny molecules improved the extrapolation performance. Additionally, the PDOS prediction for spectra with noise can be enhanced by using smoothing preprocess and training with specific noise data, enabling the application of the prediction model to experimental data.

Structural Changes of Aggregated Filler Particles in Elongated Rubbers through Two-Dimensional Pattern Reverse Monte Carlo Modeling

Katsumi Hagita, Tetsuo Tominaga, Ryota Yamamoto, Takuo Sone

Summary: In this study, a particle-mesh-based two-dimensional reverse Monte Carlo method was used to investigate the three-dimensional structure of nanoparticle aggregates in rubber tire treads. It was found that the characteristic cluster sizes of silica nanoparticles in end-modified styrene-butadiene rubber treads were smaller than those in nonmodified SBR treads. The deformation of the nanoparticles during stretching was modeled using a series of two-dimensional scattering patterns, and a high-connectivity cluster analysis was used to characterize the morphologies of the nanoparticles.

Practical compatibility between self-consistent field theory and dissipative particle dynamics

Katsumi Hagita, Takahiro Murashima

Summary: Self-consistent field theory (SCFT) and dissipative particle dynamics (DPD) simulations are effective methods for predicting microphase-separated structures of block copolymers (BCPs) at larger scales. The relation between the Flory-Huggins interaction parameter (chi) and segregation strength (Delta a) is empirically accepted for linear chains but needs to be verified for chains of finite sizes and/or non-linear architectures. Understanding the differences between DPD and SCFT and making improvements in SCFT calculations can enable the prediction of domain spacing (D) for BCPs synthesized with arbitrary topologies.

Rotaxane Formation of Multicyclic Polydimethylsiloxane in a Silicone Network: A Step toward Constructing Macro-Rotaxanes from High-Molecular-Weight Axle and Wheel Components

Minami Ebe, Asuka Soga, Kaiyu Fujiwara, Brian J. Ree, Hironori Marubayashi, Katsumi Hagita, Atsushi Imasaki, Miru Baba, Takuya Yamamoto, Kenji Tajima, Tetsuo Deguchi, Hiroshi Jinnai, Takuya Isono, Toshifumi Satoh

Summary: In this study, the synthesis of macro-rotaxanes consisting of high-molecular-weight axle and wheel components (macro-rotaxanes) was achieved by the topological trapping of multicyclic polydimethylsiloxanes (mc-PDMSs) in silicone networks. mc-PDMSs with more cyclic units and larger ring sizes can be quantitatively trapped in the network as macro-rotaxanes, compared to monocyclic PDMS. The damping performance of a 60 wt % mc-PDMS-blended silicone network was found to be higher than the bare PDMS network, suggesting the potential application of macro-rotaxanes as non-leaching additives for network polymers.

Model-Free Approach for Profiling of Polydisperse Soft Matter Using Small Angle Scattering

Guan-Rong Huang, Chi-Huan Tung, Lionel Porcar, Yangyang Wang, Yuya Shinohara, Changwoo Do, Wei-Ren Chen

Summary: This paper outlines a strategy for determining the size polydispersity of systems using small angle coherent scattering. By employing the method of moment expansion, the various central moments representing the average particle size, variance of particle size, and skewness of size distribution function (SDF) can be extracted from spectral analysis without bias. The effectiveness of this approach is demonstrated through numerical benchmarking and experimental validation using small-angle neutron scattering data obtained from L64 Pluronic micelles.

Miscibility and exchange chemical potential of ring polymers in symmetric ring-ring blends

Takahiro Ohkuma, Katsumi Hagita, Takahiro Murashima, Tetsuo Deguchi

Summary: The topological effect of ring polymers on miscibility was investigated by comparing ring-ring and linear-linear polymer blends. The exchange chemical potential was numerically evaluated to elucidate the topological effect on mixing free energy. The results showed that ring-ring blends were more miscible and stable than linear-linear blends with the same molecular weight, and the effect of molecular weight on the miscibility parameter was smaller in ring-ring blends.

A novel approach for the fractional SLS material model experimental identification

Stefano Amadori, Giuseppe Catania

Summary: This article presents a multi-step, iterative technique for locally non-parametric identification of the standard linear solid (SLS) material model using fractional order time differential operators. Test input data consists of a set of identified material complex modulus values estimated at different frequency values obtained from input-output experimental measurements and quasi-static relaxation measurements on the same specimen. The proposed technique is based on an algebraic procedure to solve an overdetermined system of linear equations in order to obtain optimal values for the unknown parameters of the model. The procedure is non-parametric, as the order of the SLS model is initially unknown.
