Summary: This study conducted an LCA of bio-based asphalts using lignin and found that the climate change impact of lignin-based asphalts could be 30-75% lower than conventional asphalts. Factors to reduce the environmental impact include increasing bitumen substitution and using low-grade biomass fuels. Trade-offs were observed in other environmental impact categories.

Summary: Photonic crystals with rainbow structural colors have been successfully fabricated through centrifugation-assisted assembly of lignin nanoparticles. The centrifugation process serves to classify the nanoparticles and produce monodispersed layers, resulting in gradient colors. The dynamic rearrangement of the lignin nanoparticles during assembly into semi-closed structures is crucial for the formation of photonic crystals.

Summary: Concerns about the health and environmental effects of current sunscreens have led to the search for safer and more efficient alternatives from natural sources. However, current improvements in sunscreens involve complex formulations and expensive nanotechnologies, making them impractical. In this study, a simple and efficient strategy utilizing naturally reproducible tea polyphenols was used to create a biocompatible, antioxidative and light-colored sunscreen with only UVB absorption. The resulting nanoparticle-based sunscreen demonstrated strong antioxidative activity, good anti-UV performance and photostability, and provided effective protection against photodamage.

Summary: This contribution describes the self-assembly of colloidal nanodumbbells (NDs) with tunable shapes within cylindrical channels. The intrinsic concave geometry of NDs endows them with peculiar packing and interlocking behaviors, leading to a variety of super-structures. A mechanistic investigation reveals that the phase behavior of NDs under strong confinement can be rationalized by the entropy-driven maximization of the packing efficiency. An empirical phase diagram is generated based on the experimental results, which could provide general guidance in the design of intended superstructures from NDs. This study provides essential insight into how the interplay between the particle shape and confinement conditions can be exploited to direct the orientationally ordered assembly of concave nanoparticles into unusual superlattices.
