Summary: In this study, the in situ dynamic crystallization properties of industrial soda-lime-silica glasses at realistic processing temperatures were investigated. Unique crystalline phases were observed at lower temperatures, and high-temperature stable SiO2 polymorphs were also observed. The main predictor variables in the previously developed liquidus temperature models were found to be questionable, and a large difference between glass processing and liquidus temperatures was identified.

Summary: The glass formation region and thermodynamic properties of Na2O-BaO-B2O3 system were investigated. The lower border of glass formation region was found to be limited to compositions containing 10-30 mol.% Na2O, 10-30 mol.% BaO and 60 mol.% B2O3. A region of partial crystallization was also observed within the glass formation region, limited to compounds with 5 Na2O-20 BaO-75 B2O3 mol.% and 10 Na2O-20 BaO-75 B2O3 mol.%.

Summary: By establishing quantitative correlations among compositions, elastic constants, GFA, and mechanical properties of metallic glasses (MGs), it is possible to predict their performance in advance. Experimental data confirms the validity of this predictive approach. A strategy for designing MGs with optimal combinations of strength, toughness, and GFA is proposed to allow for high-throughput discovery of glass formers with excellent mechanical properties.

Summary: Aluminosilicate glasses and melts play a crucial role in geo-and materials sciences but a general model for predicting their properties is lacking. A deep learning framework 'i-Melt' is introduced to accurately predict various properties of glasses and melts, including viscosity, density, and optical refractive index. The study shows that high potassium aluminosilicate melts have different structures and higher viscosities, potentially influencing the eruptive dynamics of volcanic systems.

Summary: A new exponent beta has been proposed to characterize the glass forming ability of metallic nano-glasses (NGs) and metallic glasses (MGs), showing that higher beta values indicate enhanced GFAs in NGs with a higher volume fraction of glass-glass interfaces (GGIs), which can potentially overcome the size limitation issue in MGs.

Summary: The effect of yttrium (Y) on the glass-forming ability (GFA), mechanical properties and corrosion of (Cu50Z-r43Al7)100-xYx alloys was studied. The addition of Y improved the GFA of Cu50Zr43Al7 alloy, with a GFA of 15 mm obtained for (Cu50Zr43Al7)98Y2. The bulk metallic glasses (BMGs) exhibited limited plastic strain but achieved high compressive fracture strength and Young's modulus. The corrosion resistance of the BMGs was improved by the addition of Y.

Summary: The development of Co-Ta-B-Si bulk metallic glasses with high glass-transition temperature, large compressive plasticity, high strength, and high glass-forming ability was achieved by accurately tuning the metalloid element contents of Si and B in the parental alloy. The improvement in plastic deformation was attributed to the self-organization behaviors of high-density shear bands.

Summary: Non-volatile memories and memristors are desirable for their fast and non-destructive read out of resistive state. Ferroelectric tunnel junctions (FTJs) with high resistive state ratios are promising for neuromorphic computing. A novel approach utilizing a Schottky barrier for optical sensing of resistive state in FTJs is presented, enabling optical detection of resistive state changes.

Summary: The anomalous Hall effect (AHE) in ferromagnets can be caused by intrinsic and extrinsic mechanisms. The interplay between correlated physics and topological phenomena at the interface between a ferromagnet La0.7Sr0.3MnO3 and a semimetallic SrIrO3 results in a large AHE with high anomalous Hall conductivity and Hall angle values.

Summary: In this study, highly asymmetric polymer blends with significantly different original glass transition temperatures were examined using molecular dynamics simulations. The composition-dependent behavior of the systems was clarified by establishing models and studying the density against temperature. The results showed that the dynamics of the polymer blends exhibited similar behavior with ionic systems but with different time scales.

Summary: We demonstrate the fabrication of field-effect transistors based on single-layer MoS2 and a thin layer of BaTiO3 (BTO) dielectric. The thin BTO provides a high-kappa gate dielectric effectively screening Coulomb scattering centers. These devices show higher mobilities compared to standard SiO2 dielectrics and are comparable to devices using hexagonal boron nitride. The ferroelectric character of BTO induces a robust hysteresis in the current vs gate voltage characteristics, making it attractive for memory storage applications. Our results open up possibilities for integrating complex oxides with strongly correlated physics in 2D-based devices.

Summary: Interfacial inversion symmetry breaking can lead to electronic properties different from those of bulk materials. In this study, an artificial ferromagnetic quasi-two-dimensional electron gas (q2DEG) was achieved at the (111) interfaces of LaAlO3, EuTiO3, and SrTiO3, where the bulk quasioctahedral crystal field was reconfigured into a trigonal one. The q2DEG was formed through electron transfer to the EuTiO3 layers at the interface with LaAlO3, extending into the first layers of SrTiO3. Interestingly, polarized X-ray absorption spectroscopy revealed that the Eu-4f and Ti-3d magnetic moments exhibited ferromagnetic ordering and showed the same magnetic field dependence at low temperature. Additionally, the q2DEG displayed a significant in-plane orbital moment even at low magnetic fields (0.1 T), possibly due to Ti-3d electrons occupying bands with a predominant a1g orbital character.
