Despite decades of studies, the nature glass transition remains elusive. In particular, sharpness dynamical arrest a melt at is captured by its fragility. Here, we reveal that fragility governed medium-range order structure. Based on neutron-diffraction data for series aluminosilicate glasses, propose measurable structural parameter features strong inverse correlation with fragility, namely, average distance (MRD). We use in-situ high-temperature neutron-scattering to discuss physical origin...
We report on the Raman analysis of wurtzite single-crystalline bulk AlN under hydrostatic pressures up to 10 GPa. The pressure dependence phonon frequencies was investigated. Mode Grüneisen parameters 1.39, 1.57, 1.71, 0.93, and 1.26 were determined for A1 (TO), E1 E2 (high), (LO), quasi-longitudinal optical phonons, respectively. Recent theoretical calculations underestimate pressure-induced frequency shift phonons by about 20%–30%. compared those GaN.
Ring size distribution of silicate glass can be determined from the first sharp diffraction peak neutron structure factor.
Exploring the coupling coordinated development of carbon emission reduction and sequestration (CERS) food security in agriculture is conducive to mitigating climate change achieving sustainable goals. However, there little research on these two systems. Based panel data 31 Chinese provinces from 2001 2021, this study used dynamic fuzzy set qualitative comparative analysis (fsQCA) method analyze levels driving paths between agricultural CERS security. The results revealed that (1)...
The glassy state of zeolitic imidazolate frameworks (ZIFs) has shown great potential for energy-related applications, including solid electrolytes. However, their thermal conductivity (κ), an essential parameter influencing dissipation, remains largely unexplored. In this work, using a combination experiments, atomistic simulations, and lattice dynamics calculations, we investigate κ the underlying heat conduction mechanism in ZIF glasses with varying ratios (Im) to benzimidazolate (bIm)...
Magneto-optical (MO) glasses with a high Verdet constant and wide transparency window are of fundamental significance for multifunctional applications. However, the Faraday effect can be affected by effective content valence-state variation rare-earth ions. Herein, strategy introducing Ce2O3 to rationally reduce part Tb4+ Tb3+ using levitation technique embed high-content paramagnetic ions into glass is proposed herein improve MO response. Tb2O3/Ce2O3-codoped different Tb2O3 contents...
We report on the Raman analysis of phonon lifetimes A1(LO) (longitudinal optical) and E2(high) phonons in bulk AlN crystals their temperature dependence from 10 to 1275 K. Our experimental results show that amongst various possible decay channels, primarily into two equal energy (Klemens model), most likely longitudinal-acoustic phonons, whereas decays asymmetrically a high-energy low-energy phonon. Possible channels have been shown include combinations E2(low) acoustic phonons. Phonon 0.75...
Micro-Raman scattering measurements were performed on bulk wurtzite AlN crystals over a temperature range from 10 K to 1275 K. The dependence of the frequency phonons follows an empirical relationship previously introduced for diamond. A temperature-induced shift E 2 phonon -(2.22±0.02)×10 -2 cm -1 /K was determined high temperatures, which is similar values reported GaN. results provide basis non-invasive monitoring (Al,Ga)N by Raman scattering.
Simultaneous Localization and Mapping(SLAM) has become an essential function of the robot, but existing SLAM algorithms cannot work robustly stably in a glass environment, especially when using low cost sensors. In this paper, we propose efficient robust method to detect based on multi-sensor fusion technology ultrasonic laser scan data. By integrating detection algorithm with SLAM, have improved provide more accurate mapping localization results. On basis, proposed new robot navigation...
