Life cycle environmental assessment of marine debris and post-consumer waste plastics into asphalt pavements

Cleaner Environmental Systems
This study evaluates locally adapted recycling strategies for marine derelict fishing gear (DFG) and post-consumer waste (PCW) plastics in Hawaiʻi using a life cycle assessment (LCA) framework. Comparative cradle-to-gate LCAs were conducted to assess the

Collection of Marine Debris by Jointly Using UAV-UUV With GUI for Simple Operation

IEEE Access, 2021
In recent years, floating debris in the sea has damaged the environment and harmed wildlife. Systems for collecting floating marine debris in the open ocean by installing a huge net or using a vacuum device have been proposed. However, to the best of our

Through Diamond Robust Surface Enhanced Raman Spectroscopy

Advanced Functional Materials, EarlyView.
Thin film diamond growth offers a unique opportunity for Surface Enhanced Raman Spectroscopy (SERS); the encapsulation of plasmonic nanostructures within a transparent, chemically stable, and physically robust coating. The diamond acts as both a window and protective layer, enabling illumination of the plasmonic nanostructures through the diamond ...

Rise velocity of small polyolefin plastics in a seawater tank exposed to natural conditions in Hawai’i

Environmental Research Communications
Floating plastic is ubiquitous at the ocean surface, but the transport mechanisms associated with the type of particle and the effect of environmental parameters, including the presence of a biofilm on the polymers, are very limited.

Underestimated activity-based microplastic intake under scenario-specific exposures

Environmental Science and Ecotechnology
Despite increasing alarms over the health impacts of microplastics (MPs) due to their detection in human organs and feces, precise exposure evaluations remain scarce.

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

Advanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

Separation of microplastics from deep-sea sediment using an affordable, simple to use, and easily accessible density separation device

Microplastics and Nanoplastics
Microplastics accumulate in the environment but methods to extract particles from sediment for quantification and identification often lack accuracy and reproducibility.

Abundance, patterns, and taxa associations of anthropogenic marine debris on reefs in the middle Florida Keys

Frontiers in Marine Science
The Florida Keys reef tract has rapidly shifted from a structurally complex, hard coral-dominated reef to a less rugose, soft coral-dominated reef. This transition has been facilitated by persistent anthropogenic stressors including recreational and ...
