This study reports the fabrication and evaluation of layered scaffolds based on polylactide/polycaprolactone (PLPC) matrices for osteochondral-inspired designs. Bilayer architectures comprised a bone-facing layer with mi...

In nanocomposites containing single wall carbon nanotubes (SWCNTs), the final properties strongly depend on the dispersion quality of these fillers. Various methods have been used to improve the dispersion of nanofillers...

This review aims to critically investigate the swelling behavior of natural fiber-reinforced composites (NFRCs), with a focus on identifying key mechanisms of moisture absorption, the influence of fiber–matrix interact...

ABSTRACT Cancer metastasis is the leading cause of cancer‐related mortality, involving complex interactions between tumor cells and the mechanically heterogeneous tumor microenvironment. The cell nucleus serves as a ce...

Abstract Solar arrays are the primary energy source for spacecraft. Although traditional rigid solar arrays improve power supply, the quality increases proportionally. Hence, it is difficult to satisfy the requirements o...

Abstract Backgrounds Nickel-titanium (NiTi) rotary instruments are widely used in endodontics because of their flexibility and superelasticity. However, the cyclic fatigue resistance of ORODEKA and M3-L systems in curved...

The discontinuities distributed in underground structures are the important factors that affect the mechanical characteristics of rock mass, and to study the mechanical behavior of rock discontinuities under cyclic loadi...

The chemically synthesizable quantum emitters such as quantum dots (QDs), fluorescent nanodiamonds (FNDs), and organic fluorescent dyes can be integrated with an easy-to-craft quantum nanophotonic device, which would be ...

Abstract Large-diameter monopiles are extensively used to support onshore bridges, port terminals, and offshore wind farms due to their high load-bearing capacity, low settlement and excellent seismic performance. Meanwh...

Effective-medium approaches, such as the coherent potential approximation, are commonly used to describe the rigidity transition of disordered elastic networks. While successful in capturing the universal critical behavi...

This work introduces a novel geometrical and analytical modeling framework for predicting the stiffness properties of knitted composites, a class of materials known for their complex architectures and versatile mechanica...

Heterostructured materials comprise domains with markedly different properties whose interactive coupling produces synergistic effects beyond the rule of mixtures. As the field advances, a key question is how to distingu...

Basalt fiber is a kind of inorganic material, which is effective and environmentally friendly. Basalt fiber concrete has important mechanical advantages to control the deformation of soft rock tunnels because it has func...

The sealed loading environment during the compaction process prevents the mechanical behavior of cyclotetramethylenetetranitramine (HMX) under compression from being fully understood. Elucidating the mechanical behavior ...

This work investigates the structure and magnetic properties of chitosan based films with different contents of magnetic nanoparticles (MNPs) of around 10 nm as well as the effects of the addition of glycerol as plastici...

In order to verify the reasonableness of two stress state variables for unsaturated soils and to improve the accuracy of tests, the triaxial apparatus for conventional unsaturated soils has been improved to control the p...

In recent years, the study of the static and dynamic mechanical behavior of porous functionally graded material (PFGM) structures has attracted much interest. However, most of the existing studies analyze their static or...

Nowadays, there is a growing concern about the damage caused by waste in the environment, which implies the generation of new processes and habits to contribute to a circular economy. This work explores a new alternative...

Abstract Traditional metallic materials usually face a dilemma between high strength and poor strain hardening capacity. However, heterogeneous structured metallic materials have been found to obviously overcome the trad...

Chiral photonic-band structure provides technical benefits in the form of a self-assembled helical structure and further functional wavelength tunability that exploits helical deformation according to pitch changes. The ...

Food texture is increasingly recognized as a determinant of nutritional safety, metabolic regulation, and overall health. However, conventional approaches to texture modification rely primarily on hydrocolloids, mechanic...

Compounds from the metasternal and Brindley´s glands of the blood-sucking bug, Triatoma infestans, were identified by solid phase microextraction (SPME) and gas chromatography-mass spectrometry.Volatile compounds releas...

A quantum-mechanical many-particle system may exhibit nonlocal behavior in that measurements performed on one of the particles can affect a second one that is far apart. These so-called entangled states are crucial for t...

Abstract To investigate the long-term creep behavior of deep granite in geological repositories for high-level radioactive waste under coupled temperature and stress conditions, a full-time temperature–stress coupled c...
