Radiocarbon dating of micro-inclusions of organic material extracted directly from massive ice samples was carried out at the Laboratory of Radiocarbon Dating and Electron...

Field studies of the Eastern Chukotka's massive ice carried out in 2016, 2017, and 2020. The three key sites of the studied massive ice bodies are located on the coast of...

The values of δ18О in the ice wedges of northern Chukotka and paleotemperature characteristics during the Late Pleistocene and Holocene. Winter mean (twint.mean) and January...

Syngenetic ice wedges have been investigated on Ayon Island. Their isotope composition and the geochemical characteristics of both ice wedges and enclosing sediments have been...

Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This...

We propose to investigate the interfacial adsorption of a series of water-soluble single chain PC surfactants using neutron reflection, focusing on assessing the effects of...

The aims of the experiment are (1) to obtain structural data for the model hydrogen storage intermetallic LaNi5 under a deuterium pressure of 3000 bar at cryogenic temperatures,...

It is well known that Ni-Zr amorphous alloys are highly resistant to pulverization due to the repetition of the hydrogen absorption and desorption unlike Ni-Zr crystalline...

Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This...

The interaction of ammonia with binary hydrides (prototypically, the interaction of LiH with ammonia gas) is thought to be the predominant interaction for hydrogen production...

As part of an ongoing effort to understand the underlying physics of MOFs, we propose to study the local structure and dynamics in two quartz-like systems: indium deuterium...

DINS is capable of observing coherent tunneling of protons in a double well potential through the effects of the tunneling on the momentum distribution of the protons. In our...

Composition and content of water-soluble salts in the syngenetic ice wedges of the 25–30-m Late-Pleistocene yedoma and in the modern ices and the water reservoirs of Ayon...

The composition and content of water-soluble salts in the syngenetic permafrost deposits of the 25–30-m Late- Pleistocene yedoma of Ayon Island.

(1) = According to (Tarakanov et al., 1974)(2) = According to (Noveishie otlozheniya i paleogeografiya pleistotsena Chukotki, 1980)

Variations in δ18О values in the Late-Pleistocene (pIW) and Holocene (hIW) ice wedges and segregated ice schlieres (SIS) ices of Ayon Island.# = Isotopic analyses were...

14C dates of organic remains in ice wedges from middle and lower parts of Seyakha yedoma and enclosing sediments (edge part of yedoma exposure). Calibrated using OxCal 4.4...

14C dates of organic remains in ice wedges and enclosing sediments (central part of Seyakha yedoma exposure). Calibrated using OxCal 4.4 equipped with IntCal 20 (Reimer et al....

14С dating of fragments of yedoma sequences in the north of Western Siberia, δ18О values of ice wedges of isolated fragments and reconstructed approximate mean January air...

Stable isotope (δ18О, δ2H and dexc) minimum, mean and maximum values for ice wedges exposed in yedoma deposits in the area of the Seyakha settlement, east coast of the Yamal...
