Effects of land use on Soil Organic Carbon fractions in soils of Njala Landscape in Sierra Leone [PDF]

, 2016
Soil organic carbon fractions reflect the difference in soil organic carbon from one land use to another, and it can be regarded as an indication of the degree of soil organic carbon deterioration or improvement.

Impacts of condensable particulate matter on atmospheric organic aerosols and fine particulate matter (PM _2.5 ) in China

Atmospheric Chemistry and Physics, 2022
Abstract. Condensable particulate matter (CPM) emitted from stationary combustion and mobile sources exhibits high emissions and a large proportion of organic components. However, CPM is not generally measured when conducting emission surveys of PM in most countries, including China.

PEDOT‐Based Eutectogel Electrode Arrays for Enhanced High‐Resolution Electrogastrography: Fabrication, Stability, and Wearable Performance

Advanced Functional Materials, EarlyView.
Here, we present a high‐density PEDOT eutectogel electrode array for enhanced body surface gastric mapping. Silver electrodes are blade‐coated onto flexible substrates, followed by electrogelation of PEDOT:PSS and the deposition of a PEDOT:LS eutectogel.

Geomorphic complexity influences coarse particulate organic matter transport and storage in headwater streams

Frontiers in Water, 2023
Coarse particulate organic matter (CPOM; organic matter 1–100 mm in diameter, excluding small wood) stored in streams provides an important energy source for aquatic ecosystems, and CPOM transport provides downstream energy subsidies and is a pathway for

Particulate Organic Matter as a Soil Quality Indicator of Sugarcane Plantations in East Java [PDF]

, 2012
This study is aimed to test the hypothesis that the soil quality of sugarcane plantations closely linked to the particulate organic matter (POM) and earthworm's populations. The research was conducted at five sites in Malang, East Java.

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Organic Matter Controls of Iron Incorporation in Growing Sea Ice

Frontiers in Earth Science, 2018
This study presents the first laboratory-controlled sea-ice growth experiment conducted under trace metal clean conditions. The role played by organic matter in the incorporation of iron (Fe) into sea ice was investigated by means of laboratory ice ...

Rapid Cycling of Bacterial Particulate Organic Matter in the Upper Layer of the Western Pacific Warm Pool

Geophysical Research Letters, 2023
Bacterial metabolism largely drives the sequestration of refractory organic matter in the ocean. However, a lack of understanding exists regarding the abundance and reactivity of bacterial particulate organic matter (POM).
