GRACE gravity solutions validated by in-situ ocean bottom pressure in different regions of the global ocean [PDF]

open access: yes, 2009
The GRACE satellite mission provides gravity field estimates of the Earth with unprecedented accuracy. Nevertheless,the realistic detection of oceanic mass redistribution remains challenging due to comparatively small signalamplitude, aliasing by tides ...

3D Printed Ultra‐Fast Plastic Scintillators Based on Perovskite‐Photocurable Polymer Composite

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The demand for radiation detection is increasing in a number of fields, including high‐energy physics, medical imaging, and homeland security. This study serves to demonstrate the potential for the fabrication of fast perovskite‐based scintillators with complex shapes via stereolithographic additive manufacturing, representing a new path toward the ...

Ocean Economics [PDF]

open access: yes, 2015
Supply and demand is alive and well on the high seas. Just ask Finn McMichael ’16. He spent the summer putting his economics and math skills to work during an internship at the Northeast Fisheries Science Center, part of the National Marine Fisheries ...

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

The Possible Explanation for Secondary Microseisms Seasonal and Annual Variations

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
Annual drift is typical for microseisms. We propose a model based on thermoelastic wave generation that explains the highest microseisms during winter using higher stress level at the same time. If we remove the average influence of the background stress

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Isotopic evidence for biogenic molecular hydrogen production in the Atlantic Ocean [PDF]

open access: yes, 2015
Oceans are a net source of molecular hydrogen (H2) to the atmosphere. The production of marine H2 is assumed to be mainly biological by N2 fixation, but photochemical pathways are also discussed.

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...
