Synergistic Fluorine and Cyanide Co‐Modification to Reinforce Photoinduced Excitons Formation and Transfer for Efficient CO2 Photoreduction

open access: yesAdvanced Functional Materials, EarlyView.
An advanced F‐doped and ─CN group co‐modified FCCN is developed. Due to the synergistic effects of co‐modification in promoting photogenerated exciton generation, enhancing charge kinetics, expanding active interfacial areas, and optimizing CO2 interfacial reactions, the FCCN photocatalyst demonstrates excellent catalytic performance and high ...

Resistivity image beneath an area of active methane seeps in the west Svalbard continental slope [PDF]

open access: yes, 2016
The Arctic continental margin contains large amounts of methane in the form of methane hydrates. The west Svalbard continental slope is an area where active methane seeps have been reported near the landward limit of the hydrate stability zone.

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

open access: yesAdvanced Functional Materials, EarlyView.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Dual‐Functional Additive Regulating Zn2+ Solvation Structure and (002) Plane‐Oriented Deposition for Dendrite‐Free Zn Anodes

open access: yesAdvanced Functional Materials, EarlyView.
Sulfosalicylic acid (SSA) is introduced as a bifunctional additive for Aqueous zinc‐ion batteries. SSA reconstructs the solvation structure of Zn2+ through the synergistic effects of its multiple functional groups, suppressing side reactions while selectively promoting Zn (002) deposition to prevent dendrite formation.

Distinct expressions of the BSR using various frequencies offshore Uruguay and its correspondence with the gas hydrate stability zone [PDF]

open access: yes, 2011
At the Uruguayan continental margin, seismic evidence for the occurrence of gas hydrate has been identified based on the presence of BSRs in densely spaced 2D reflection seismic sections from different surveys.

High‐Yield Synthesis of Fe‐NC Electrocatalysts Using Mg2+ Templating and Schiff‐Base Porous Organic Polymers

open access: yesAdvanced Functional Materials, EarlyView.
Fe─NC porous oxygen reduction electrocatalysts are prepared employing a 2,4,6‐Triaminopyrimidine‐based porous organic polymer, a Mg2+ Lewis acid, and a low‐temperature cation exchange protocol. Using the polymer precursor achieves high pyrolysis yields and results in atomically dispersed FeNx sites. The resulting catalysts feature hierarchical porosity

Acoustic sensing of gas seeps in the deep ocean with split-beam echosounders [PDF]

open access: yes, 2012
When in the form of free gas in the water column, methane seeps emanating from the seabed are strong acoustic targets that are often detectable from surface vessels using echo sounders.In addition to detecting that a seep is present at some location, it ...
