Functional Upcycling of Polyurethane Thermosets into Value-Added Thermoplastics via Small-Molecule Carbamate-Assisted Decross-Linking Extrusion.

The cross-linked structures of most commodity polyurethanes (PUs) hinder their recycling by common mechanical/chemical approaches. Catalyzed dynamic carbamate exchange emerges as a promising PU recycling strategy, which converts traditional static PU thermosets into reprocessable covalent adaptable networks (CANs). However, this approach has been limited to thermoset-to-thermoset reprocessing of PU CANs, accompanied by their well-preserved network structures and extremely high viscosities, which pose challenges to processing and certain applications.

Molecular identity crisis: environmental DNA metabarcoding meets traditional taxonomy-assessing biodiversity and freshwater mussel populations (Unionidae) in Alabama.

The use of environmental DNA (eDNA) to assess aquatic biodiversity is a growing field with great potential for monitoring and managing threatened species, like freshwater mussel (Unionidae) populations. Freshwater mussels are globally imperiled and serve essential roles in aquatic systems as a food source and as a natural water filter making their management essential for ecosystem health. Unfortunately, mussel populations are often understudied, and challenges exist to accurately and efficiently describe the full suite of species present.

Park Visitors' Place Attachment and Climate Change-related Displacement: Potential Shifts in Who, Where, and When.

Visitation to parks will change with increasing climate changes. We examined how place attachment may influence different types of climate-induced displacement at both the park and park system level. Previous research suggests that visitors who have greater place attachment to parks within a system may be more likely to tolerate changed environmental conditions before they are displaced from the system entirely or change their choice of park or time of visit within it.

Impacts on soil nitrogen availability of converting managed pine plantation into switchgrass monoculture for bioenergy.

Biofuels derived from lignocellulosic materials is one of the options in addressing issues on climate change and energy independence. One of the most promising bioenergy crops is switchgrass (Panicum virgatum L.), particularly in North America.

Geopharmaceuticals of Himalayan Sowa Rigpa medicine: Ethnopharmacological uses, mineral diversity, chemical identification and current utilization in Bhutan.

Ethnopharmacological Relevance: Geological materials, such as minerals, have a long history of usage as ingredients in multicompound formulations of Himalayan Sowa Rigpa medicine - as well as in its localized form of Bhutanese traditional medicine (BTM) - for treating various disorders for over thousand years. Yet, hardly any scientific research has been done on their ethnopharmacological efficacy and chemistry.

Aim Of The Study: This study documents and correlates the rarely explored ethnopharmacological and chemical identification of various minerals and their ethnomedicinal uses in BTM formulations for the first time.
