Advanced Functional Materials, EarlyView.Two isomorphic COFs were synthesized and compared, including an amphoteric COF (SQ‐TAPT) and a neutral COF (PDA‐TAPT). The ionic bonds in SQ‐TAPT introduce more Born effective charges, thereby enhancing its ionic displacement polarization. Experimental and theoretical calculations demonstrated that SQ‐TAPT exhibited higher polarity and stronger ...

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing
Advanced Functional Materials, EarlyView.A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Arctic Coastal Sea Ice Dynamics
Offshore Technology Conference, 1974Abstract In the period March through August, 1973, sea ice movement was observed off Barrow, Alaska, on the Chuck chi Sea coast with a land based radar. It is concluded that during the breakup period, July and early August, the ice movement is predominantly determined by ocean currents parallel to the coast and that

Reverberation under Arctic Sea-Ice
The Journal of the Acoustical Society of America, 1967Backscattering strengths were obtained from polar pack ice in the Beaufort Sea during April 1965. The ice surface in the experimental area consisted of 10%–15% of pressure ridges separating random patches of 1 yr ice. The results cover a frequency range of 40 to 10240 Hz and a grazing-angle range of 5°–85°. Comparison with earlier results obtained with

Ice is an important physical feature of the environment in polar regions and strongly affects the plants and animals living in these areas. Ice reduces the amount of light reaching the water column, and also reduces heat and gas exchange. A salinity minimum directly beneath the ice and reduced mixing of the water combine to enhance the vertical ...

Arctic Ocean-Sea Ice Interactions
Proceedings of the Practice and Experience on Advanced Research Computing, 2018This animation visualizes simulation results from research at The University of Texas at Austin, Institute for Computational and Engineering Sciences. Shown is the daily average temperature field of warm sub-surface water of subtropical origin carried with the Norwegian Atlantic boundary current into the Arctic Ocean, northwestward along the West ...

ARCTIC, 1965
Reviews investigations 1961-1963 into chlorophyll concentrations in sea ice in both arctic and antarctic regions. Results are compared with own researches off Devon Island, Canada, which are reported in detail. Chlorophyll a and c concentrations were obtained from underside of ice by a 7.5 cm diam ice corer and light penetration was measured by ...
