Road Markings for Reliable Visual Guidance and Sustainability

IntechOpen eBooks, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Road markings—inalienable elements of almost all paved roads worldwide responsible for the safe guidance drivers—are described from perspective materials. The characteristics road markings as dual-layer speciality industrial maintenance coatings, along with their key performance parameters, are explained. Results field and laboratory evaluations various materials utilised to present issues associated visibility both human drivers machine vision equipment. topic sustainability is addressed based on outcome tests; carbon footprint representative a long-term (i.e., series renewals maintain properties, appropriate in cases deteriorating systems) given. issue microplastic emissions discussed; newest results used demonstrate inadequacies earlier theoretical estimates. Emerging concepts, such luminescent markings, criticised due low practical applicability. Good practice recommendations maximise properties users given reference administrators scientists.

Tire-Road-Wear Particles and Glass Beads in the Gizzard of the Endangered Terrestrial Bird, Okinawa Rail (Hypotaenidia okinawae)

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 17, 2025

This study analyzed microplastics and glass beads (GBs; an indicator of traffic-derived particulate contamination) in 42 gizzards endangered terrestrial bird, the Okinawa rail (Hypotaenidia okinawae). Black rubber fragments (BRs) were found 57% specimens (1–184 items/individuals), GBs 48% (1–32 items/ind.). FTIR identified rubbers as same materials used tire tread. A significant positive correlation was between abundances BRs (p < 0.01), suggesting source exposure pathway. Large quantities BRs, namely tire-road-wear particles (TRWPs), also environmental samples (road dust, roadside soil, side-ditch sediment) diet organisms (earthworm, millipede, snail). The characteristics these (appearance, material type, size distribution) consistent gizzard contents samples. concentration ratio similar to that sediment organisms, especially earthworms. These results indicate rails are exposed contaminants including TRWPs via ground-feeding along roadside. To our knowledge, this is first evidence bird species.

Probing the microbiome in stormwater pipeline sediments: Co-occurrence patterns and novel functionalities

Current Research in Biotechnology, Journal Year: 2024, Volume and Issue: 7, P. 100199 - 100199

Published: Jan. 1, 2024

Stormwater pipeline is an essential pathway to transfer stormwater runoff into nearby receiving water bodies. Understanding the composition, co-occurrence patterns, and function of microbial communities in sediments can help provide management control strategies for pollution safeguard safety ecological health urban environment. This study employs 16S rRNA gene amplicon sequencing probe a highly urbanized area Guangzhou, China. Results show that sediment bacterial community rich Listeria, Prevotella, Stenotrophomonas, Pseudomonas, which all pertain pathogens. Methanogens (Methanobacterium, Methanosaeta, Methanosarcina, Methanobrevibacter) ammonia-oxidizing archaea (Ca. Nitrosopelagicus, Ca. Nitrososphaera, Nitrosotenuis) dominated archaeal sediments. These functions are further validated by prediction overall community. The network microbe-environment correlation analyses suggest particulate C-N-P components play more crucial role, comparison dissolved ones regulating microbiome, although not samples follow this mechanism. findings expected contribute systems valuable guidance improving environmental well-being ecosystems.

Vibration-assisted Microbead Production: A New Frontier for Biocompatible Surfaces

Royal Society of Chemistry eBooks, Journal Year: 2024, Volume and Issue: unknown, P. 251 - 285

Published: Nov. 15, 2024

The encapsulation of active pharmaceutical ingredients (APIs) in microbeads is an essential step drug delivery; however, it also inherently associated with the need to control particle size and release profiles. Nevertheless, most conventional methods microencapsulation fail provide consistent results. A new method called vibration-assisted microbead coating a novel unified technique utilizing mechanical vibrations enable controlled, uniform on APIs. This chapter discusses technology performed by authors through formation physical activity focuses achieving final coated surface API, shape, size, loading vibration parameters. Additionally, this biocompatibility stability surface. means has high potential for delivery. reduces traditional challenges encapsulation, if not eliminates them, more reliable. Based abovementioned findings, propose following main areas their further work: optimisation parameters various APIs, research into long-term loading–release profile, possible use targeted
