Organic Biogeochemistry in West Mata, NE Lau Hydrothermal Vent Fields

Geochemistry, Geophysics, Geosystems, 2021
The impact of submarine hydrothermal systems on organic carbon in the ocean—one of the largest fixed carbon reservoirs on Earth—could be profound. Yet, different vent sites show diverse fluid chemical compositions and the subsequent biological responses.

Temperature Dependence of Photodegradation of Dissolved Organic Matter to Dissolved Inorganic Carbon and Particulate Organic Carbon

PLOS ONE, 2015
Photochemical transformation of dissolved organic matter (DOM) has been studied for more than two decades. Usually, laboratory or "in-situ" experiments are used to determine photodegradation variables. A common problem with these experiments is that the photodegradation experiments are done at higher than ambient temperature.

Multifunctional Bio‐Based Packaging for Perishable Foods: Structural Design, Scalable Fabrication, and Versatile Applications

Advanced Materials, EarlyView.
An overview of design principles and scalable fabrication strategies for multifunctional bio‐based packaging. Radiative cooling films, modified‐atmosphere films/membranes, active antimicrobial/antioxidant platforms, intelligent optical/electrochemical labels, and superhydrophobic surfaces are co‐engineered from material chemistry to mesoscale structure

Components of organic carbon pool and profile distribution of δ¹³C values in typical stagnic anthrosols from Hangzhou-Jiaxing-Huzhou Plain

浙江大学学报. 农业与生命科学版, 2010
Three typical stagnic anthrosols, including silty-clayey yellow mottled paddy soil on fluvialmarine, blue clayey paddy soil, and gleyed blue clayey paddy soil, were collected from the Hangzhou-Jiaxing-Huzhou Plain to characterize vertical distribution of

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

Advanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

Coupling the PLANKTOM5.0 marine ecosystem model to the OCCAM 1º ocean general circulation model for investigation of the sensitivity of global biogeochemical cycles to variations in ecosystem complexity and physical environment [PDF]

, 2008
The earliest marine ecosystem models consisted of a simple representation of the main features of marine ecosystems, including, typically, variables for phytoplankton, zooplankton, nutrient and detritus (NPZD models).

Fate of metals in coastal sediments of a Mediterranean flood-dominated system: An approach based on total and labile fractions [PDF]

, 2011
The dynamics of sediment-bound metals (Cs, Cu, Ni, Pb, Ti and Zn) were studied off the Têt River (western Gulf of Lion), a typical Mediterranean coastal river punctuated by short and violent flash-floods.

Dissolved and particulate organic carbon in Icelandic proglacial streams [PDF]

, 2018
Abstract. Here for the first time, we analyze the concentration of dissolved (DOC) and particulate organic carbon (POC), as well as its optical properties (absorbance and fluorescence) in proglacial streams of Iceland, location of Europe's largest nonpolar ice cap. DOC and POC concentrations range from 0.11 mg L−1 to 0.94 mg L−1 and from 0.67 mg L−1 to

3D Printing of Highly Dense and Translucent Zirconia Parts for Dental Applications: Effect of Filament Overlapping

Advanced Materials Technologies, EarlyView.
This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.

Bacterial-viral interactions in the sea surface microlayer of a black carbon-dominated tropical coastal ecosystem (Halong Bay, Vietnam)

Elementa: Science of the Anthropocene, 2018
Increasing human activity has raised concerns about the impact of deposition of anthropogenic combustion aerosols (i.e., black carbon; BC) on marine processes. The sea surface microlayer (SML) is a key gate for the introduction of atmospheric BC into the
