Influence of Secondary Patterning on the Crystalline Quality of Epitaxial GaN Films

Abstract Molecular dynamics simulations were employed to investigate the effects of planar, single-patterned, and secondary-patterned epitaxy on the crystalline quality of GaN thin films. Secondary-patterned epitaxy significantly improves atomic ordering, promotes the formation o...

Physical Activity and Depressive Symptoms in Guangdong University Students: A Cross-Sectional Moderated Serial Indirect-Association Model Involving Self-Esteem, Positive Psychological Capital, and Perceived Social Support

Background: This cross-sectional study examined whether physical activity was indirectly associated with depressive symptoms through self-esteem and positive psychological capital and whether these associations varied by perceived social support. Methods: Data from 473 students a...

Effect of Mortar Surplus Coefficient on the Mix Design and Performance of Granite Tunnel Slag Aggregate Concrete

To facilitate the graded resource utilization of granite tunnel slag (GTS), the mix proportions of GTS aggregate concrete were optimized using the mortar surplus coefficient (MSC) as a mix-design parameter. Concrete mixtures with different MSC values were designed by adjusting th...

Volcanic textures control the mechanical behaviour of Mesoamerican obsidians

Abstract Obsidian—natural volcanic glass—was exploited for millennia and played a central role in the technological and socio-economic development of pre-Hispanic societies across Mesoamerica. The selection of obsidian from specific deposits has been linked to differences in visu...

Channel two-phase flow validation and dynamics in proton exchange membrane fuel cells under water-boiling-point temperature conditions

With the growing demand for green energy, proton exchange membrane fuel cells (PEMFCs) have developed worldwide. Increasing the operating temperature to the water-boiling-point range (100–120 ℃) can significantly enhance the heat dissipation capacity, but it induces more complex...

Nanoconfinement-cooperated catalysis enables rapid tandem redox kinetics for wide-temperature lithium-sulfur batteries

The slow kinetics of sulfur cathodes caused by the high energy barriers of Li + desolvation stem primarily from the structure of the inner Helmholtz plane (IHP). Herein, a synergistic strategy combining electrochemical tandem catalysis with spatial nanoconfinement is proposed to...

Pesticide Spraying Strategy Optimization for a Tracked Air-Assisted Spraying Robot Based on a Novel Virginia Creeper Optimization Algorithm

To address the limitations of conventional constant-rate pesticide application in adapting to spatial variations in crop canopy structure, this study proposes a pesticide spraying strategy optimization method for a tracked air-assisted spraying robot based on a novel Virginia Cre...

Empowering Drivers as Collaborative Social Agents: Enhancing Pedestrian Interaction through Cooperative Interfaces in Autonomous Vehicle Systems

While autonomous driving technology reduces the operational burden on drivers, it may also diminish their sense of engagement, for example, by interrupting social interactions between drivers and other road users such as pedestrians. To address this, this article proposes a “Soci...

HEMA and PPG Enable Simultaneous Control of Overcuring and Debinding Defects in Photopolymerizable β-Tricalcium Phosphate Ceramic Printing Slurries

Abstract Ceramic parts fabricated by vat photopolymerization often suffer from pores, delamination, and cracks, which greatly limit their development, mainly due to poor slurry flowability, high polymerization shrinkage stress of the resin, and insufficient removal of organics. T...
