Abstract:
... Although there is widespread agreement about the need to reduce teenagers’ consumption of sugar-sweetened beverages, banning these drinks from the school environment is not always feasible. In this paper, we tested whether increasing the assortment of healthier alternatives and clearly labelling them as healthy by means of traffic light coding qualifies as an alternative approach to reduce the con ...

Abstract:
... There are indications in the literature that extrinsic parameters, such as the color of the plate, might be important for people’s appreciation of a meal. Here we compared the preferences of two groups of differently aged children with those of adults.Participants rank-ordered images of 4 familiar dishes presented on six plates of different colors (achromatic: black, white; chromatic: yellow, gree ...

Abstract:
... The quantification of microplastics in environmental samples often requires an observer to determine whether a particle is plastic or non-plastic, prior to further verification procedures. This implies that inconspicuous microplastics with a low natural detection may be underestimated. The present study aimed at assessing this underestimation, looking at how colour (white, green and blue), size (l ...

Abstract:
... Consumers are often surrounded by somatosensory (e.g., warmth) and visual (e.g., color) information. For example, consumers often see light-colored goods under warm conditions. Previous studies have shown that sensory interactions, such as those involving auditory and visual stimuli, influence consumer behaviors. However, it remains unknown whether somatosensory–visual information (e.g., warmth an ...

Abstract:
... The production of patterned photonic films on a large scale remains a challenge. Here, we report on a new class of photonic materials that are based on oxetane liquid crystals (LCs). Patterned reflective coatings can be produced from these materials on flexible substrates by using flexographic printing. This industrially relevant process allows for upscaling in future applications. Furthermore, th ...

The parent microbelt cavity together with the optically allowed 0–1 transition of H-aggregates enables a microlaser to operate at 585 nm. Upon HCl vapor treatment, the protonation of surface molecules shifts the lasing wavelength to 560 nm, generating an in ...

Abstract:
... Colourful flowers and artefacts are frequently used in modern landscape architecture and in site-specific artwork. Despite this, there is limited empirically substantiated understanding of the impact of colour on perceptions of the soft, changing green colour palette of surrounding vegetation, and thus the overall colour perception of green spaces. Applying the CIE 1976 (L*a*b*) colour space, this ...
