Surface functionalization plays an important role in the design of biomedical implants, especially when layer forming cells such as endothelial or epithelial cells are needed. In this study, we define a novel nanoscale surface coating composed of collagen/alginate polyelectrolyte multilayers and crosslinked for stability with genipin. This buildup follows an ...

Having good spatial skills strongly predicts achievement and attainment in science, technology, engineering, and mathematics fields (e.g., Shea, Lubinski, & Benbow, 2001; Wai, Lubinski, & Benbow, 2009). Improving spatial skills is therefore of both theoretical and practical importance. To determine whether and to what extent training and experience can improve ...

The naturally abundant elements used to catalyze photochemical processes in biology have inspired many research efforts into artificial analogues capable of proton reduction or water oxidation under solar illumination. Most biomimetic systems are isolated molecular units, lacking the protective encapsulation afforded by a protein's tertiary structure. As such, advances in ...

Studies on the health behaviour of adolescents mostly examine single health behaviour indicators in a separate manner for each one. However, health behaviours are not independently developed, but occur within a broader behavioural scheme acquired during socialisation. The aim of this study is to analyse the distribution of health-related behaviour ...

Abstract Trans-host effects can alter the ecological and evolutionary dynamics of parasite and host populations. Here, we examine whether resource limitation within a parasite's natal host affects propagule size and influences parasite fitness in a new host. To alter resource competition, we infected caterpillars with 3 doses of the nematode ...

Many of graphene's unique electronic properties emerge from its Dirac-like electronic energy spectrum. Similarly, it is expected that a nanophotonic system featuring Dirac dispersion (two conical bands touching at a single point, the so-called Dirac point) will open a path to a number of important research avenues. To date, however, ...

Fully substituted 4-amino pyrrolones are easily accessed via simple routes starting from imines, ketones, or alpha-bromo phenylacetonitriles. Imines were reacted with KCN/NH4Cl in aqueous ethanol to produce alpha-arylamino benzylcyanides. On the other hand, ketones were transformed to the desired alpha-amino nitriles using a modified Strecker reaction. Then, alpha-amino nitrile precursors ...
