Effect of Ethanol on Microbial Community Structure and Function During Natural Attenuation of Benzene, Toluene, and \u3cem\u3eo\u3c/em\u3e-Xylene in a Sulfate-reducing Aquifer [PDF]

open access: yes, 2008
Ethanol (EtOH) is a commonly used fuel oxygenate in reformulated gasoline and is an alternative fuel and fuel supplement. Effects of EtOH release on aquifer microbial ecology and geochemistry have not been well characterized in situ.

Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Sulfide- and nitrite-dependent nitric oxide production in the intestinal tract [PDF]

open access: yes, 2011
In the gut ecosystem, nitric oxide (NO) has been described to have damaging effects on the energy metabolism of colonocytes. Described mechanisms of NO production are microbial reduction of nitrate via nitrite to NO and conversion of l-arginine by NO ...

Maya Blue‐Inspired Hybrid Coating for Robust and Superhydrophilic Solar Evaporators Using Commercial Black Acrylic Paint

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates a Maya blue‐inspired hybrid solar evaporator using commercial black acrylic paint, achieving 98% solar‐thermal conversion efficiency and 2.39 kg m−2 h−1 water evaporation rate through a durable, hydrophilic organic–inorganic structure that enables scalable, cost‐effective desalination and wastewater purification.

Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter [PDF]

open access: yes, 2017
Sulfate reduction plays an important role in altering dissolved organic matter (DOM) in estuarine and coastal sediments, although its role in the production of optically active chromophoric DOM (CDOM) and a subset of fluorescent DOM (FDOM) has not been ...

Methane-related changes in prokaryotes along geochemical profiles in sediments of Lake Kinneret (Israel) [PDF]

open access: yesBiogeosciences, 2015
Microbial methane oxidation is the primary control on the emission of the greenhouse gas methane into the atmosphere. In terrestrial environments, aerobic methanotrophic bacteria are largely responsible for this process.

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

open access: yesAdvanced Functional Materials, EarlyView.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.
