A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Passage kinetics of concentrates in dairy cows measured with carbon stable isotopes

Animal, 2013
Fractional passage rates form a fundamental element within modern feed evaluation systems for ruminants, but knowledge on feed-specific fractional passage is largely lacking. Commonly applied tracer techniques based on externally applied markers, such as

A paleolimnological archive of metal sequestration and release in the Cumberland Basin Marshes, Atlantic Canada

FACETS, 2017
We used a paleolimnological approach at Long Lake, Nova Scotia, to construct a 10 500-year record of metal deposition in lakebed sediments and elucidate the influence of both natural and anthropogenic environmental changes.

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

Advanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...

Smart alloys for a future fusion power plant: First studies under stationary plasma load and in accidental conditions

Nuclear Materials and Energy, 2017
In case of an accident in the future fusion power plant like DEMO, the loss-of-coolant may happen simultaneously with air ingress into the vacuum vessel. The radioactive tungsten and its isotopes from the first wall may become oxidized and vaporized into

The role of soil components in synthetic mixtures during the adsorption and speciation changes of Cr(VI): Conjunction of the modeling approach with spectroscopic and isotopic investigations

Environment International, 2019
This study investigates redox transitions associated with the adsorption of Cr(VI) on commonly occurring soil components (silicates, oxides and humic acids) and their synthetic mixtures by coupling the mechanistic surface complexation modeling with ...

Diffusion of Hydrogen Isotopes in Zirconium Alloys

He huaxue yu fangshe huaxue
Tritium is a common radioactive product in nuclear power plants. It is easy to diffuse, penetrate and be easily absorbed by organisms due to its small atomic radius.

Chromium isotopic anomalies in Allende Refractory Inclusions

Geophysical Research Letters, 1984
Measurements of both 53Cr/52Cr and 54Cr/52Cr ratios with a precision of 10−4 in Allende inclusions display widespread chromium isotopic anomalies which are in the range of 5• 10−4. Instrumental mass fractionation precludes specific identification of the affected isotopes, but there are strong arguments favoring excesses in 54Cr and a hint of a very ...

An analytical procedure for determination of sulphur species and isotopes in boreal acid sulphate soils and sediments

Agricultural and Food Science, 2008
An analytical scheme suitable for boreal acid sulphate (AS) soils and sediments was developed on the basis of existing methods. The presented procedure can be used to quantify and discriminate among acid volatile sulphide, cold chromium reducible sulphur,
