Nanozyme‐Integrated Hydrogel Targeting AGEs for Diabetic Osteoarthritis Therapy

Advanced Science, EarlyView.
A nanozyme–integrated hydrogel (PTC‐MP) exhibiting with mild photothermal effects is constructed, and a “3R” (restrain‐restore‐reinforce) strategy is proposed for diabetic osteoarthritis (DOA) treatment based on advanced glycation end products (AGEs) targeting.

Valuing Blue Carbon Changes in the Arctic Ocean

Frontiers in Marine Science, 2019
The ocean capacity to store carbon is crucial, and currently absorbs about 25% CO2 supply to the atmosphere. The ability to store carbon has an economic value, but such estimates are not common for ocean environments, and not yet estimated for the Arctic

Arctic Ocean fresh water changes over the past 100 years and their causes [PDF]

, 2008
Recent observations show dramatic changes of the Arctic atmosphere–ice–ocean system. Here the authors demonstrate, through the analysis of a vast collection of previously unsynthesized observational data, that over the twentieth century the central ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

Advanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Arctic HYCOS – 1st Workshop on Improved Monitoring, Accuracy and Data Availability in the Arctic Drainage Basin: Meeting Summary Report and Implementation Plan [PDF]

, 2012
The World Hydrological Cycle Observing System (WHYCOS) is a global programme, developed in response to the scarcity or absence of accurate, timely and accessible data and information in real or near real time on freshwater resources in many parts of the ...

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

Advanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy

Advanced Science, EarlyView.
An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...

Control of primary production in the Arctic by nutrients and light: insights from a high resolution ocean general circulation model [PDF]

Biogeosciences, 2010
Until recently, the Arctic Basin was generally considered to be a low productivity area and was afforded little attention in global- or even basin-scale ecosystem modelling studies.

A circumpolar perspective on fluvial sediment flux to the Arctic ocean [PDF]

, 2002
Quantification of sediment fluxes from rivers is fundamental to understanding land‐ocean linkages in the Arctic. Numerous publications have focused on this subject over the past century, yet assessments of temporal trends are scarce and consensus on ...
