Summary: This study demonstrates the importance of particle shape in determining fragility in glass-formers made of hard polyhedral particles. By studying local structure and bond angle distributions, it was found that systems with increasingly tetrahedral particle shapes become stronger. The research provides a direct link between the local geometry of fluid structure and glass formation properties, showcasing the possibility of engineering fragility in colloidal systems through slight changes in particle shape.

Summary: The relaxation of supercooled liquids near the glass transition is controlled by activated processes, which become dominant below the dynamical crossover predicted by Mode Coupling theory (MCT). Dynamic facilitation theory (DF) and the thermodynamic scenario are two main frameworks explaining this behavior. Only particle-resolved data can reveal the microscopic mechanism of relaxation in liquids supercooled below the MCT crossover. Using advanced GPU simulations and nano-particle resolved colloidal experiments, the elementary units of relaxation in deeply supercooled liquids are identified to be excitations of DF and cooperatively rearranging regions (CRRs).

Summary: The emergence of slow glassy dynamics in materials is believed to be encoded in their microstructure. By extending mode-coupling theory (MCT) to include higher-order static and dynamic correlations, researchers have found that static triplet direct correlations as well as higher-order dynamic correlations play non-negligible roles in both fragile and strong glassformers. The addition of static triplet correlations qualitatively changes the predicted glass-transition diagram and reveals a competition between stabilizing static triplet correlations and destabilizing dynamic higher-order correlations.

Summary: The study showed that with increasing B2O3 content, the TeO4 and BO4 structural units in the glass decreased, while BO4 and BO3 units increased; density decreased, molar volume increased. The introduction of B2O3 caused an increase in conductivity, but conductivity decreased after exceeding 50 mol% of B2O3.

Summary: This study explores the effects of quenched disorder on frustrated systems by considering random fluctuations on the antiferromagnetic interactions between spins on the checkerboard lattice. The results show that competing interactions lead to highly frustrated scenarios when the ratio J(2)/J(1) approaches 1.

Summary: In this study, the correlation effects on the structural and thermodynamic properties of hard- and soft-core polymer models were compared using the polymer reference interaction site model (PRISM) theory. Different behaviors of the soft-core models were observed at large invariant degree of polymerization (IDP) depending on how IDP is varied. Additionally, an efficient numerical approach was proposed to accurately solve the PRISM theory for chain lengths as large as 10(6).

Summary: The application of curved glass in modern wavy enclosures provides great design freedom. The stiffness resulting from curvature decreases support requirements and improves esthetics or increasing spans. However, there are concerns regarding its design, manufacture, and performance during operation, especially with the limited ability of Insulating Glass Units (IGUs) to equalize internal and atmospheric pressure. This study investigates the influence of geometric parameters on internal pressure through experiments and Finite Element simulations of flat and cylindrically curved IGUs.

Summary: Geometrically frustrated elastic ribbons exhibit significant shape transitions depending on the relationship between their width and thickness, with the existence and scaling of these transitions strongly dependent on the system being considered. By using an asymptotic approach and treating width as a small parameter, the leading energy terms causing frustration were identified, allowing for the prediction of the shape transition's existence and scaling. Five different types of frustrated ribbons were studied in detail, showing sharp or moderate shape transitions at critical widths, with the approach's predictions matching experimental results from various geometric settings.

Summary: This article discusses the universality and specificity of molecular dynamics in the glass transition of liquids, comparing results from different experimental methods. Nuclear magnetic resonance (NMR) measurements show that translation is more retarded than rotation in liquids with fully established hydrogen-bond networks. NMR susceptibilities of the structural relaxation resemble light scattering, while the dielectric spectra of polar liquids have different broadening. NMR measurements confirm the characteristic feature of the alpha-relaxation near the glass transition. NMR is advantageous in selectively studying specific molecular entities or components of liquid mixtures.

Summary: This study investigates the growth of 2D crystals of colloidal nanoparticles on cylindrical substrates using a combination of experiment and simulation. The cylindrical geometry influences how the crystals grow, resulting in kinked line slips containing partial vacancies. The closure constraint of the cylinder leads to frustrated crystal growth, impacting the formation of structures such as chiral optical nanomaterials.

Summary: Polycrystalline compounds of breathing pyrochlore LiInCr4-xNTxO8 (x = 0, 0.1, 0.2, 0.4) were synthesized and their structure, magnetism, and dielectric properties were investigated. The size of the Ni substituted samples decreased, and Raman scattering indicated higher atomic mass and increased bond strength. Magnetic measurements revealed a spin-glass state and suppression of long-range magnetic order at high Ni contents. The spin gap gradually vanished with increasing nickel concentration, and the dielectric constant decreased with increasing frequency.

Summary: This study thoroughly characterizes the disordered microphases of systems with competing short-range attractive and long-range repulsive interactions, and assesses the efficiency of various advanced Monte Carlo sampling schemes. The combination of VMMC and AVBMC is found to be the most computationally efficient for cluster fluids, while ECMC becomes relatively more efficient as density increases. The results provide a complete description of the equilibrium disordered phase and dynamical benchmarks for other sampling schemes.

Summary: The formulation of mean-field infinite-dimensional solution of hard sphere glasses is a significant advancement in theoretical physics. However, its relevance in understanding low-dimensional glass-forming liquids is still unclear. By revisiting simulation techniques and leveraging standard liquid-state theory, the study of hard sphere liquids up to d = 13 has become possible, helping to bridge the gap between different approaches.

Summary: This study reveals that the local dynamical fluctuations of particles in glass-forming models display divergent behavior around the glass transition due to nontrivial correlations between displacements along different directions. This phenomenon leads to the emergence of a divergent non-Gaussian parameter and provides a first-principle explanation for its growth around the glass transition without relying on multiparticle correlations.

Summary: The random Lorentz gas (RLG) serves as a minimal model for transport in disordered media, but theoretical understanding of its properties remains limited, especially in scaling with dimension at the localization transition. A recent study has highlighted physical inconsistencies in the scaling of caging behavior of RLG, emphasizing the need for further guidance. The study extended analytical expectations for void percolation threshold and computationally evaluated its criticality in various dimensions, revealing a dynamical slowdown in high-d systems reminiscent of mean-field caging.

Summary: The paper introduces a numerical transfer matrix approach to address disputed features of the phase diagram of the two-dimensional axial next-nearest-neighbor Ising model, confirming transition temperatures and the order of the transition to the floating incommensurate phase. The approach suggests using transfer matrices to solve longstanding problems in related models.
