In this research we designed and constructed a system from a local materials and tested for measuring the thermal conductivity coefficient of thermally good conducting materials  in the temperature range (25–150 c°)....

Abstract Biological load-bearing materials, like the nacre in shells, have a unique staggered structure that supports their superior mechanical properties. Engineers have been encouraged to imitate it to create load-bear...

With the growing interest in the field of artificial materials, more advanced and sophisticated functionalities are required from phononic crystals and acoustic metamaterials. This implies a high computational effort and...

In the development of silicon photonics, the continued downsizing of photonic integrated circuits will further increase the integration density, which augments the functionality of photonic chips. Compared with the tradi...

The triazine backbone serves as a crucial heterocyclic scaffold in the development of energetic materials due to its high nitrogen (52%) and energy content (223 kJ/mol). Additionally, it functions as an environmentally b...

According to the fractal theory, the fractal distribution formula of gradation for rockfill materials is deduced. The field gradation data of six dams with clay core and five 200 m-high CFRDs are used to verify the relev...

There are several reasons why English language teachers may embark on the endeavor to develop teaching and learning materials for the EFL population in rural schools. This book presents some of those reasons by means of ...

This work includes materials aimed at training graduates and updating practising professionals in the framework of early intervention. It also integrates new biomedical engineering professionals. It contains information ...

Are you interested in Art and the Humanities? Have you been learning English for a long time but do not have enough confidence to carry out tasks in these fields efficiently? Would you like to learn the necessary strateg...

Resonancias Tectónicas: Del diseño centrado en el usuario a un diseño orientado en el planeta El pabellón de Chile que nos representó en la Bienal Londres es un nuevo diseño, que reflexiona sobre cómo tratar a los...

BACKGROUND Materials by design is an appealing idea that is very hard to realize in practice. Combining the best of different ingredients in one ultimate material is a task for which we currently have no general solution...

Abstract Although several research works in the literature have focused on studying the capabilities of additive manufacturing (AM) systems, few works have addressed the development of Design for Additive Manufacturing (...

Radiative cooling is a passive cooling strategy that leverages thermal radiation to dissipate heat into a cooler environment, offering an energy-efficient and environmentally friendly alternative to conventional cooling ...

Abstract The use of non-smart materials in structural components and kinematic pairs allows for flexible assembly in practical applications and is promising for aerospace applications. However, this approach can result i...

The raising demand for efficient and stable energy sources for indoor applications demands the development of high-performance photovoltaic (PV) materials. This study examines the potential of the all-inorganic CsPbIBr2 ...

Auxetic materials, defined by their negative Poisson’s ratio, exhibit enhanced toughness, energy absorption, and improved shape retention, making them attractive for aerospace, biomedical, and flexible electronics appl...

We report the design of a high-throughput gradient hyperbolic lenslet built with real-life materials and capable of focusing a beam into a deep sub-wavelength spot of λ/23. This efficient design is achieved through high...

The design criteria of Terzaghi filter layer have laid the foundation for the researches on filter layers, which are safet enough for uniform cohesionless soil, but not secure for uneven cohesionless soil, and they are n...

Optically active point defects in wide-bandgap crystals are leading building blocks for quantum information technologies including quantum processors, repeaters, simulators, and sensors. Although defects and impurities a...

Here, we report a selective multilayer emitter for eco-friendly daytime passive radiative cooling. The types of materials and thickness of up to 10 layers of the multilayer structure are optimized by a genetic algorithm....

Abstract As for the complex operational tasks in the unstructured environment with narrow workspace and numerous obstacles, the traditional robots cannot accomplish these mentioned complex operational tasks and meet the ...
