RX J1548.9+0851, a fossil cluster? [PDF]

, 2012
Fossil galaxy groups are spatially extended X-ray sources with X-ray luminosities above L_X,bol > 10^42 h_50^-2 ergs s^-1 and a central elliptical galaxy dominating the optical, the second-brightest galaxy being at least 2 magnitudes fainter in the R ...

Lewis Pair‐Engineered CuMnOx as Cold‐Adapted Multinanozyme for Cooperative Hydrolytic and Oxidative Degradation of Raw Corn Stalk

Advanced Science, EarlyView.
A Lewis pair site design strategy was established to construct Cu‐doped Mn‐based amorphous nanozymes, where Mn and oxygen vacancies generate cooperative acid‐base pairs. The resulting multinanozyme integrates glycosidase‐, oxidase‐, and cold‐adapted enzyme‐mimicking activities, enabling cooperative depolymerization of cellulose and hemicellulose ...

First known fossil bird tracks (Pleistocene) on San Salvador island, Bahamas

Geologica Acta, 2015
Two avian footprints discovered in the Grotto Beach Formation (Pleistocene) of San Salvador Island (Bahamas) are the first known vertebrate trace fossils on this well-studied island. The trace fossils, preserved as beddingplane impressions in an oolitic-

Sedimentology and Ichnology of Paleozoic Estuarine and Shoreface Reservoirs, Morrow Sandstone, Lower Pennsylvanian of Southwest Kansas, USA [PDF]

, 1999
Integration of facies and trace-fossil evidence tests and refines depositional models constructed solely on the basis of physical sedimentology. In recent years, the petroleum industry has increasingly used trace-fossil analysis of cores as an aid in ...
