Effect of direct aging on microstructure, mechanical properties and shape memory behavior of Fe-17Mn-5Si-10Cr-4Ni-(V, C) shape memory alloy fabricated by laser powder bed fusion
The global plastic waste crisis remains a fundamental challenge for mankind to address, as vast amounts of plastic continue to accumulate in the environment, threatening ecosystems and human health. Biobased and biodegradable plastics, particularly materia ...
Despite the rapid development of small‐area perovskite solar cells (PSCs), the performance limitations of large‐area perovskite solar modules (PSMs) hinder their commercialization. Uncontrolled crystallization kinetics and complex environmental factors in ...
The role of light elements in ceramic materials cannot be overestimated. By tuning their concentration, a whole multitude of mechanisms can be activated, directly influencing the material's functional properties. However, accurate determination of light el ...
In shale testing, understanding the impact of effective stress and saturation conditions is crucial for accurate material behaviour assessment and parameter determination. In some cases, saturation in triaxial testing starts at low effective stress before ...
Reinforcing bars in structural concrete are typically designed to carry axial forces. Nevertheless, due to their bending stiffness, the bars can also carry transverse forces, that are associated with the localized bending mechanism (dowel action) resulting ...
In fracture mechanics, polyacrylamide hydrogel has been widely used as a model material in experiments due to its optical transparency, the brittle nature of its failure, and low Rayleigh wave velocity. Indeed, linear elastic fracture mechanics has been us ...
Flexoelectricity is universal in all dielectrics, effective at high temperatures, and a promising transduction technique for nanoelectromechanical systems (NEMS). However, as flexoelectricity is still in its early stages, many aspects require further inves ...
Achieving control in the design of monolayer 2D functional catalysts represents a significant challenge. If that challenge is surmounted, coordinated single-metal-atom sites can offer tailored electronic configuration, ligation geometries, chemical activit ...
Metal-halide perovskites-based optoelectronic devices, such as solar cells and light-emitting diodes (LEDs), are transitioning from promising performers to direct competitors to well-established technologies due to the advantage of cost-effectiveness. Pero ...
Balling is one of the cornerstone defects in laser powder bed fusion of metals, leading to high porosity of the 3D printed parts and substantially deteriorating their performance. The transition to the balling mode is commonly identified through a series o ...
This study aimed to identify the fatigue crack initiation site of high-frequency mechanical impact (HFMI)-treated high-strength steel welded joints subjected to high peak stresses; the impact of HFMI treatment residual stress relaxation being of particular ...
Applications of photovoltaic (PV) cells in buildings are often excluded from locations with major mechanical strains because of their brittleness and possible damages at small mechanical strains. Combinations of glass fibre reinforced polymer (GFRP) compon ...
2H-NbSe2 is a prototypical charge-density-wave (CDW) system, exhibiting such a symmetry-breaking quantum ground state in its bulk and down to a single-atomic-layer limit. However, how this state depends on dimensionality and what governs the dimensionality ...
