Sorption of polycyclic aromatic hydrocarbons on particulate organic matters [PDF]

Journal of Hazardous Materials, 2010
Particulate organic matter (POM) is a key organic matter fraction which can influence soil fertility. Its interactions with hydrophobic organic pollutants (HOCs) have not been characterized and the mechanisms of retention of HOCs by POM remain unclear. In the present study, sorption behaviors of polycyclic aromatic hydrocarbons (PAHs) naphthalene (NAP),

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

The unique biogeochemical role of carbonate-associated organic matter in a subtropical seagrass meadow

Communications Earth & Environment
The particulate organic matter buried in carbonate-rich seagrass ecosystems is an important blue carbon reservoir. While carbonate sediments are affected by alkalinity produced or consumed in seagrass-mediated biogeochemical processes, little is known ...

An 11,000-year record of depositional environmental change based upon particulate organic matter and stable isotopes (C and N) in a lake sediment in southeastern Brazil [PDF]

, 2018
The aim of this paper is to reconstruct an 11,000-year history of depositional environmental change in southeastern Brazil, based upon the integration of particulate organic matter and stable isotope (C and N) data from a 136-cm sediment core from Lake ...

Shaping of Biohybrid Functional Living Materials

Advanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Frações lábeis e estáveis da matéria orgânica do solo sob sistemas de manejo e cerrado nativo [PDF]

, 2010
A matéria orgânica do solo pode ser estudada por meio de suas diferentes frações. Alterações dos teores de matéria orgânica, ocasionadas pelo uso do solo, podem ser mais bem compreendidas pelas mudanças nos seus diferentes compartimentos.

Biological Formation of Organic Substances from Particulate Organic Matter

Canadian Chemical Transactions, 2015
Biological degradation of terrestrially derived macromolecules including lignin and cellulose has been shown to produce a large number of environmentally relevant phenolic compounds. It has demonstrated that extracellular superoxide (O2  ) is produced by heterotrophic bacteria that are common in lakes, soil, hydrothermal vents, marine sediments ...

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Soil depth distribution of particulate organic carbon and nitrogen in the southeastern United States

Agricultural & Environmental Letters
Particulate organic matter may be an important component feeding soil microbial activity. This study described population‐level statistics of particulate organic carbon (C) and nitrogen (N) in predominately Ultisols across 181 farms throughout North ...
