Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

open access: yesAdvanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Approaches for refining pack ice driving force estimates for the Beaufort Sea

open access: yes
There are large oil and gas resources in the shear zone region of the Beaufort Sea. Development of these resources would entail many factors for consideration. One of the most important is the ice load on drilling and production platforms. However, there

Analyses of structure of planetary boundary layer in ice camp over Arctic ocean [PDF]

open access: yes, 2007
The vertical structure of Planetary boundary layer over Arctic floating ice is presented by using about 50 atmospheric profiles and relevant data sounded at an ice station over Arctic Ocean from 22 August to 3 September, 2003. It shows that the height of

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

A Distinctive Large Breeding Population of Ringed Seals (Phoca hispida) Inhabiting the Baffin Bay Pack Ice

open access: yes, 1983
Aerial surveys in June and July, 1978 and 1979, documented an unexpectedly large population (at least 417,000) of ringed seals, some with pups, inhabiting the pack ice of Baffin Bay.

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

open access: yesAdvanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure

open access: yesAdvanced Materials, EarlyView.
The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...

Arctic Geophysics

open access: yes, 1969
The modern phase of geophysical research began at Barrow in 1944 with exploration of Naval Petroleum Reserve No.4. The asymmetric sedimentary basin below the Arctic coastal plain was discovered and defined, using gravity, magnetic and seismic methods.

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

open access: yesAdvanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

Ship/pack ice interaction with wave effect

open access: yes, 1991
The motion of pack ice caused by the incident wave action, and the interaction between the ship and ice pieces are studied in this paper. The problem is divided into two parts: a) the motion of an ice piece caused by the incident wave action; and b) the ...
