Structure-dependent colour is caused by the interaction of light with photonic crystal structures rather than pigments. The elytra of longhorn beetles Tmesisternus isabellae appear to be iridescent green in a dry state and turn to red when exposed to humidity. Based on the hygroscopic colouration of the longhorn beetle, we have developed centimeter-scale colorimetric opal films using a novel se...

The present paper constitutes a review of the literature on young infants' chromatic discrimination capabilities. A series of early studies showed that infants as young as two months postnatal can make at least some chromatic discriminations between stationary, homogeneous fields of different wavelength compositions. Current studies of spatial and temporal contrast sensitivity functions (CSFs) ...

We show how to use the Hopf algebra structure of quantum field theory to derive nonperturbative results for the short-distance singular sector of a renormalizable quantum field theory in a simple but generic example. We discuss renormalized Green functions GR(α,L) in such circumstances which depend on a single scale L = ln q /μ and start from an expansion in the scale GR(α,L) = 1 + ∑ k γk(α)L ....

Green spaces in residential communities are important yet understudied features of the urban ecological system. While large urban parks and remnant wildlands in urban areas tend to receive public attention from conservation and management perspectives, less is known about the importance of spatial and ecological characteristics of the community-scale green space. This study investigates natural...

In the preceding accompanying paper [Shu, X., et al. (2007) Biochemistry 46, 12005-12013], the 1.5 A resolution crystal structure of green fluorescent protein (GFP) variant S65T/H148D is presented, and the possible consequences of an unusual short hydrogen bond (<or=2.4 A) between the carboxyl oxygen of Asp148 and the phenol oxygen of the chromophore are discussed. This work reports the femtose...

This paper reviews the experimental synthesis and engineering developments that focused on various green approaches and large-scale process production routes for quantum dots. Fundamental process engineering principles were illustrated. In relation to the small-scale hot injection method, our discussions focus on the non-injection route that could be scaled up with engineering stir-tank reactor...
