Location of a new ice core site at Talos Dome (East Antarctica)
In the frame of glaciology and palaeoclimate research, Talos Dome (72°48lS; 159°06lE), an ice dome on the East Antarctic plateau, represents the new selected site for a new deep ice core drilling. The increasing interest in this region is due to the fact

Age stratigraphy in the East Antarctic Ice Sheet inferred from radio-echo sounding horizons [PDF]
The East Antarctic Ice Sheet contains a wealth of information that can be extracted from its internal architecture such as distribution of age, past flow features, and surface and basal properties.

Helicopter-borne radio-echo sounding of Svartisen, Norway [PDF]
A helicopter-mounted low frequency ice-radar has been developed for the depth sounding of temperate glaciers. The radar consists of standard transmitter and digital receiver equipment. The long antennae are supported on a special aluminium and fibreglass construction which hangs 20 m below the helicopter. The radar has been used on Engabreen, an outlet

A Miniaturized Autonomous Thermomagnetic Generator
Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

Surface Clutter Suppression Techniques for Ice Sounding Radars: Analysis of Airborne Data [PDF]
For the ice sounding of Antarctica from space, a P-band radar at 435 MHz is the only option which complies with present ITU regulations. At this frequency the ice surface cannot be considered smooth, leading to high ambiguous returns.

Radio-Echo Sounding: Focusing Effects in Wavy Strata [PDF]
Summary An airborne radio-echo sounding system, employing a wide downward-looking beam, has produced records of the Antarctic ice sheet containing fault-like, near-vertical lines through the strata of partially-reflecting layers within the ice. It is shown that interpretation of these lines as near-vertical faults is in general incorrect, and a more

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Radio Echo-Sounding of Riiser-Larsenisen (Abstract only) [PDF]
The Norwegian Antarctic Research Expedition 1978–79 used the Scott Polar Research Institute Mk IV radio echo-sounding system fitted in a Bell 206B helicopter to survey 620 km of Riiser-Larsenisen and 100 km across the outer part of Stancomb-Wills Ice Stream.

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor
Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.
