Effects of Polyvalent Cations on FTIR Spectra of Organic Matter–Cation Associations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The composition of soil organic matter (SOM) can be characterized by functional groups in the organic matter (OM). The carboxylic acid and carboxylate groups of OM show specific absorption bands in Fourier‐transform infrared (FTIR) spectra. However, cation–OM interactions may affect absorption bands and limit spectral interpretation

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Immunological Evaluation of PLLA/GO Scaffolds in Goat Mandibular Bone Regeneration

Macromolecular Bioscience, EarlyView.
PLLA/GO scaffolds interact with bone tissue by modulating the immune response and promoting regeneration in goat mandibles. Histological and immunohistochemical analyses reveal progressive tissue organization, mineral deposition, osteoblastic activity, and angiogenesis over time.

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.
