Fully Bio‐Based Gelatin Organohydrogels via Enzymatic Crosslinking for Sustainable Soft Strain and Temperature Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Enzymatically crosslinked gelatin‐based organohydrogels, fabricated through a fully bio‐based and scalable process, exhibit exceptional strain and temperature sensing capabilities with minimal interference from environmental humidity. These transparent, stretchable, and ionically conductive materials operate without synthetic fillers or dopants.

Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Arctic Coastal Sea Ice Dynamics

Offshore Technology Conference, 1974
Abstract 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, 1967
Backscattering 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

Arctic Sea-Ice Biota

1989
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, 2018
This 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 ...

Chlorophyll in Arctic Sea Ice

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 ...
