We report surface-enhanced Raman scattering (SERS) from Ag nanoparticles decorated on thin carbon nanowalls (CNWs) grown by microwave plasma chemical vapor deposition. The Ag morphology is controlled by exposing the CNWs to oxygen plasma and through the electrodeposition process by varying the number of deposition cycles. The SERS substrates are capable of detecting low concentrations of rhodam...

Nowadays recycling wastewater is a task in progress. New ways of contamination have appeared together with the technology development. Our article deals with the case of wastewater contaminated with dispersed colorants that are used during the decoration of paper boxes for packaging various products. The wastewater treatment is based on the electro-flotation process. The system is fully automat...

Sexual selection driving display trait divergence has been suggested as a cause of rapid speciation, but there is limited supporting evidence for this from natural populations. Where speciation by sexual selection has occurred in newly diverged populations, we expect that there will be significant differences in female preferences and corresponding male display traits in the absence of substant...

Glorious Fonts, a new graphically-based font type, allow interesting effects to be applied to existing character sets. The difficulties of automating this process are examined in the context of applying Celtic knotwork designs to plain text characters. An analysis of knotwork construction techniques shows how complete designs may be described by an expanded tile set. This paper also presents an...

Attack–defense trees can be used as part of threat and risk analysis for system development and maintenance. They are an extension of attack trees with defense measures. Moreover, tree nodes can be decorated with attributes, such as probability, impact and penalty, to increase the expressiveness of the model. Attribute values are typically assigned based on cognitive estimations and historicall...

In this paper, we explore haptic editing as a powerful way to enhance haptic realism. Building upon the framework of a previous implicit-based haptic technique, our haptic decoration technique allows the user to first paint directly on 3D models, and then to sense the thickness variation due to the added paint. Meanwhile, material editing permits the user to edit and feel local material propert...

We deene an optimal proof-by-proof embedding of intuitionistic sequent calculus into linear logic and analyse the (purely logical) linearity information thus obtained.

Tau is a neuronal, microtubule-associated protein that stabilizes microtubules and promotes neurite outgrowth. Tau is largely unfolded in solution and presumably forms mostly random coil. Because of its hydrophilic nature and flexible structure, tau complexed to microtubules is largely invisible by standard electron microscopy methods. We applied a combination of high-resolution metal-shadowing...

Highly sensitive hydrogen sulfide (H2S) gas sensors were developed from CuO-decorated ZnO semiconducting hierarchical nanostructures. The ZnO hierarchical nanostructure was fabricated by an electrospinning method following hydrothermal and heat treatment. CuO decoration of ZnO hierarchical structures was carried out by a wet method. The H2S gas-sensing properties were examined at different work...

On the basis of density functional theory, stability and electronic structure of nitrogen-vacancy (NV) centers in surface modified diamond have been studied. Surface decoration is traditionally expected to only have influence on those NV centers close to the surface. However, our calculations indicate that its effect to charged NV centers is nondecaying and long-range, where the formation energ...
