3D Cage COFs: A Dynamic Three-Dimensional Covalent Organic Framework with High-Connectivity Organic Cage Nodes

open access: yesJournal of the American Chemical Society, 2020
Three-dimensional (3D) covalent organic frameworks (COFs) are rare because there is a limited choice of organic building blocks that offer multiple reactive sites in a polyhedral geometry.

Dynamic and history of methane seepage in the SW Barents Sea: new insights from Leirdjupet Fault Complex

open access: yesScientific Reports, 2021
Methane emissions from Arctic continental margins are increasing due to the negative effect of global warming on ice sheet and permafrost stability, but dynamics and timescales of seafloor seepage still remain poorly constrained.

Endohedrally Doped Cage Clusters.

open access: yesChemical Reviews, 2020
The discovery of carbon fullerene cages and their solids opened a new avenue to build materials from stable cage clusters as "artificial atoms" or "superatoms" instead of atoms. However, cage clusters of other elements are generally not stable.

Sedimentary deformation relating to episodic seepage in the last 1.2 million years: a multi-scale seismic study from the Vestnesa Ridge, eastern Fram Strait

open access: yesFrontiers in Earth Science, 2023
Seafloor hydrocarbon seepage is a natural fluid release process that occurs worldwide on continental shelves, slopes, and in deep oceanic basins. The Vestnesa sedimentary ridge in the eastern Fram Strait hosts a deep-water gas hydrate system that became ...

THE IRON CAGE REVISITED:

open access: yesThe New Economic Sociology, 1983
Instead of examining why organizations are dissimilar, this study explores why organizations tend to be increasingly and inevitably homogenous in their forms and practices.

Home Cage Compared with Induction Chamber for Euthanasia of Laboratory Rats [PDF]

open access: yes, 2018
This study compared behavioral and physiologic changes in Sprague-Dawley and Brown Norway rats that were euthanizedby using a 30% volume displacement rate of CO2 in either their home cage or an induction chamber; rats euthanized in thehome cage were ...

Elucidating heterogeneous photocatalytic superiority of microporous porphyrin organic cage

open access: yesNature Communications, 2020
The investigation on the catalytic properties of porous organic cages is still in an initial stage. Herein, the reaction of cyclohexanediamine with 5,15-di[3’,5’-diformyl(1,1’-biphenyl)]porphyrin affords a porphyrin tubular organic cage, PTC-1(2H ...

Deglacial bottom water warming intensified Arctic methane seepage in the NW Barents Sea

open access: yesCommunications Earth & Environment, 2021
Phases of high bottom water temperature in the northwestern Barents Sea caused repeated destabilization of methane gas hydrates since the last glacial, according to a foraminifera Mg/Ca bottom water temperature record and hydrate stability ...
