Random multilayer (RML) structures, or aperiodic superlattices, can localize coherent phonons and therefore exhibit drastically reduced lattice thermal conductivity compared to their superlattice counterparts. The optimization of RML structures is essential for obtaining ultralow conductivity, which critical various applications such as thermoelectrics barrier coatings. A higher degree disorder in RMLs will lead stronger phonon localization and, correspondingly, a lower conductivity. In this...
This article reviews the recent progress towards achieving carbon-based thermoelectric materials. A wide range of experimental and computational studies on carbon allotropes composites is covered in this review paper. Specifically, we discuss strategies for engineering graphene, graphene nanoribbon, nanomesh, nanowiggle, nanotube (CNT), fullerene, graphyne, quantum dot better performance. Moreover, most advances CNT/graphene-polymer related challenges solutions. We also highlight important...
The characteristics of total sagittal and coronal plane parameters in children with short stature (SS) the correlations between these are currently unknown. This case-control study sought to retrospectively investigate SS examine parameters. data aged 3-15 years normal heights were collected, allocated observation control groups, respectively. following analyzed: Cobb angle, cervical lordosis (CL) T1 slope (T1S), thoracic kyphosis (TK) lumbar (LL) sacral inclination pelvic incidence axis,...
As the electromagnetic environment becomes increasingly complex and power density continues to increase, reliability safe operation of gallium nitride (GaN) high electron mobility transistors (HEMTs), which are widely used in field high-power radio frequency amplifiers, severely jeopardized. In this study, effects mechanism microwave on AlGaN/GaN HEMT amplifiers were explored. A novel effect phenomenon, is entirely distinct from reported damage GaN devices, was uncovered. This phenomenon...
Randomizing the layer thickness of superlattices (SL) can lead to localization coherent phonons and thereby reduces lattice thermal conductivity κ l . In this work, we propose strategies that suppress incoherent phonon transport in above random multilayer (RML) structure further reduce Molecular dynamics simulations are conducted investigate heat conduction SLs RMLs with imperfections. We found interfacial species mixing enhances across single interfaces few-period through "bridge"...
The structure and intrinsic magnetic properties of Sm2Fe17-xGax (0 < or = x 6) compounds were studied. These crystallize in the rhombohedral Th2Zn17-type are single phase except for Sm2Fe11Ga6 which contains some alpha -Fe. Curie temperature Tc is found first to increase then decrease with increasing x, attaining a maximum value 595 K at about 3, 208 higher than that Sm2Fe17. X-ray diffraction measurements on magnetically aligned powder samples show 1 > 5 exhibit easy-plane anisotropy while...
Twinning is a major mechanism of plastic deformation in hexagonal close-packed (hcp) structures. However, mechanistic understanding twin nucleation and growth has yet to be established. This paper reviews the recent progress twinning hcp materials—particularly newly discovered phase transformation-mediated mechanisms—in terms crystallographical analysis, theoretical mechanics calculations, numerical simulations. Moreover, relationship between mechanisms dislocations are presented, forming...
Nanocrystalline and nanotwinned metals exhibit ultrahigh strength but suffer from low ductility due to the absence of strain hardening effect. Here, we report sustained strong up 20% compressive in a melt-quenched nanocrystalline Cu structure, which contains numerous fivefold twins, stacking faults, twin boundaries. Our molecular dynamics simulations reveal that results synergistic effect constant nucleation impedance dislocations, restricted boundary migration, abundant dislocation...
Numerical simulations at nanometer scales have identified several mechanisms of plastic deformation. However, high strain rate regimes are required to resolve length scales. Extrapolating these numerical predictions rates experimental conditions remains an unresolved challenge. Phase-field dislocation dynamics (PFDD) conducted study the sensitivity deformation in nanocrystalline metals. The PFDD involve collective behavior partial and extended full dislocations ranging from 1 × 106 s−1 109...
