Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Ultra-high performance concrete

2008
ABSTRACT: The main advantage of DUCON (DUctile CONcrete), a patented 3-D micro-reinforced, selfcompacting Ultra High Performance Concrete, is its ductility in combination with high compressive and flexural strength. This paper describes the properties and recent applications of DUCON.

Basic and Drying Creep of Ultra-High Performance Concrete

SSRN Electronic Journal, 2022
Published online: 03 Apr 2023. OnlinePubl ; Experimental observations of the creep behaviour of ultra-high performance concrete (UHPC) are limited, with existing studies all performed on material designs including fibres. This limits the understanding of the underlying behaviour of the cementitious material, including the relative contributions of ...

Rehydration of Ultra High Performance Concrete

Advanced Materials Research, 2014
Ultra High Performance Concrete (UHPC) and High Strength Concrete (USC) are because of the high density of their matrices very susceptible to spalling during fire exposure. By aid of a heat treatment with maximum temperatures of about 450°C a network of capillaries and micro cracks could be formed, which leads like a porous medium to a relief of water ...
