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...

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...

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...

In this work, MCM-41 materials have been synthesized and modified with different metal loadings of iron by the wet impregnation method. The different meso-structures obtained were characterized by XRD, UVVIS-RD, ICP and ...

"In future, there will be an increasing demand for waste heat recovery systems (WHRS). So far current technologies are not expected to fulfill the requirement expected for a broad deployment. Thermoelectric generators (T...

"In the ICELABPatagonia project, different laboratories for Karukinka National Park in Chile were designed. The main objective of these laboratories was to provide shelter against the area’s tough weather conditions, s...
