Endohedrally Doped Cage Clusters.
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.

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