Dislocations are commonly present and important in metals but their effects have not been fully recognized oxide ceramics. The large strain energy raised by the rigid ionic/covalent bonding ceramics leads to dislocations with low density (∼106 mm-2), thermodynamic instability spatial inhomogeneity. In this paper, we report ultrahigh (∼109 mm-2) of edge that uniformly distributed compositional complexity. We demonstrate progressively thermodynamically stabilized increasing complexity...
Raman spectroscopy is a powerful technique to probe structural and doping behaviors of two-dimensional (2D) materials. In MoS2, the always coexisting in-plane (E2g1) out-of-plane (A1g) vibrational modes are used as reliable fingerprints distinguish number layers, strains, levels. this work, however, we report an abnormal behavior, i.e., absence A1g mode in cetyltrimethylammonium bromide (CTAB)-intercalated MoS2 superlattice. This unusual behavior quite different from softening induced by...
Single-walled carbon nanotube (SWCNT)-based thermoelectric materials have been extensively studied in the field of flexible wearable devices due to their high flexibility and excellent electrical conductivity (σ). However, poor Seebeck coefficient (S) thermal limit application. In this work, free-standing MoS2/SWCNT composite films with improved performance were fabricated by doping SWCNTs MoS2 nanosheets. The results demonstrated that energy filtering effect at interface increased S...
Abstract An in-depth understanding of the dislocations motion process in non-metallic materials becomes increasingly important, stimulated by recent emergence ceramics and semiconductors with unexpected room temperature dislocation-mediated plasticity. In this work, local misfit energy is put forward to accurately derive Peierls stress model dislocation SrTiO 3 instead generalized stacking fault (GSF) approach, which considers in-plane freedom degrees atoms near shear plane describes...
Molecular dynamics (MD) simulations are used to investigate the fundamental damping mechanism of AO-60/nitrile-butadiene rubber (AO-60/NBR) composites at molecular level in this study. The hydrogen bonds (H-bonds), binding energy, and fractional free volume (FFV) AO-60/NBR were obtained. composite with an AO-60 content 36 phr had largest H-bonds, highest smallest FFV, all indicating a good compatibility between NBR performance composite. experimental FTIR, 1H-NMR results also showed that two...
The flexible thermoelectric (TE) generator has emerged as a superior alternative to traditional batteries for powering wearable electronic devices, it can efficiently convert skin heat into electricity without any safety concerns. MXene, highly researched two-dimensional material, is known its exceptional flexibility, hydrophilicity, metallic conductivity, and processability, among other properties, making versatile material wide range of applications, including supercapacitors,...
A dual-phase Mg–Li alloy LA103Z sheet was subjected to single pass submerged friction stir processing (FSP) at various of tool sizes, rotation rates and travel speeds. The relationships between parameters, frictional heat generation, microstructure, the room-temperature tensile properties in zone were systematically investigated. Both α-Mg phase β-Li undergo complete dynamic recrystallization, grains are significant refined texture is significantly weakened. precipitation AlLi Li2MgAl...
There is an urgent demand of ultrathin high-performance microwave absorbing materials (MAMs) in the electromagnetic protection field. However, minimizing thickness challenging mainly due to dielectric mismatch at high permittivity from excessive loss, leading strong reflection 2-18 GHz. Here, a hybrid TaS2 /Co(Cp)2 superlattice fabricated with alternating [TaS2 ] inorganic layers and [Co(Cp)2 organic layers. Dynamic Ta─Co dipoles offer unique interfacial polarization relaxation mechanism...
By combining molecular dynamics simulations with experiment, the effect of acrylonitrile content on compatibility and damping properties were investigated in AO-60/nitrile-butadiene rubber composites.
Abstract Plasticity in ceramics is governed by the process of dislocation dynamics, which can be divided into four stages: nucleation, activation, motion, and multiplication dislocations. Unlike metals, exhibit distinct dynamic behavior dislocations due to their inherent properties, such as a weak ability nucleate difficulties activation. These factors contribute brittle nature pose challenges for studying plasticity. Theoretical simulations are useful tools study behaviors. In this...
Optimizing carrier concentration and transport has been demonstrated to be a practical strategy improve the thermoelectric efficacy of single-walled carbon nanotube (SWCNT)-based composite films, which have potential application in self-powered wearable electronics. In this study, nonmetallic heteroatoms (boron, sulfur, phosphorus) are selected dope g-C3N4 adjust energy band structure for fabricating g-C3N4/SWCNT with high performance. Heteroatom doping improves mobility g-C3N4, promotes...
Glucagon-like peptide-1 receptor (GLP-1R) holds pivotal importance as a therapeutic target for type 2 diabetes (T2D) and obesity. Several oral small-molecule agonists targeting GLP-1R have been developed to date. Nevertheless, these suffer from several limitations, including low potency, poor pharmacokinetics, unfavorable safety profiles. Here, we report the discovery of compound 29 (DA-302168S), which exhibits higher potency both in vitro/in vivo while mitigating risk drug-drug interaction...
With the ever increasing number of large scale Internet applications, inter data center (inter-DC) transfers are becoming more and common. Traditional inter-DC suffers from both low-utilization congestion, traffic prediction is an important method to optimize these transfers. Inter-DC harder predict than many other types network traffic, because it dominated by a few applications. We propose model that significantly reduces errors. In our model, we combine wavelet transform with artificial...
Vapor-phase infiltration, a postpolymerization modification process, has demonstrated the ability to create organic–inorganic hybrid membranes with excellent stability in organic solvents while maintaining critical membrane properties of high permeability and selectivity.
