Summary: The incorporation of graphene nanoplatelets (GPs) into conductive flexographic ink improves sheet-resistance and uniformity, as well as adhesion on paper and PET substrates. The GP-enhanced samples exhibit robust durability under 1000 cyclic bend-test, showing a minimal average variation in resistance. Statistically scalable results show that GP-incorporation offers a cost-performance advantage for flexographic printing of large-area conductive patterns.

Summary: A pyrene-based chalcone CPP with aggregation-induced enhanced emission was synthesized for fluorescent pigments, and formulated into water-based eco-friendly flexographic inks. The printed substrates displayed yellow fluorescence under UV light, and the batch ink showed superior performance in gloss, light-fastness, abrasion resistance, and colorimetric values compared to the standard ink. The study revealed the potential of CPP as a fluorescent pigment for security printing and optical-electronic devices.

Summary: Smart and mechanically flexible energy harvesting/storage devices have gained significant attention in growing markets such as electronics, automobiles, medicine, and aerospace. However, current devices face challenges in terms of installation on curved surfaces, high manufacturing costs, and limited production rates. Therefore, new design strategies involving new materials, cost-effectiveness, and scalability are necessary to meet the demands of these markets. This review aims to provide a comprehensive understanding of flexographic printing for energy devices by discussing its advantages over existing printing technologies and summarizing its application in solar cell and battery construction.

Summary: This research introduces a new biofabrication method based on the viscous fingering phenomenon, which can efficiently manufacture highly branched and interconnected channel structures. The method offers adjustable printing parameters and hydrogel formulations for fabricating channels that mimic the morphology of small blood vessels and capillaries. The fabricated networks demonstrate excellent perfusability and hold great potential for nutrient supply in thick vascularized tissues or organ-on-a-chip systems.

Summary: This study aims to understand European consumers' concerns, needs, and expectations regarding the use of intelligent packaging technologies. A qualitative user-centered approach was used to gather insights from focus group discussions in five European countries. The findings show that food safety and quality are the most important issues in the food value chain, and consumers prefer smart tag labels to provide information on ingredients, food storage, preparation, shelf life, health, freshness, recycling, and personalized deals. Quick response (QR) codes and freshness indicators are identified as the future technologies for the food industry stakeholders.
