The XMM Cluster Survey: The Stellar Mass Assembly of Fossil Galaxies [PDF]

, 2012
This paper presents both the result of a search for fossil systems (FSs) within the XMM Cluster Survey and the Sloan Digital Sky Survey and the results of a study of the stellar mass assembly and stellar populations of their fossil galaxies. In total, 17

Are fossil groups a challenge of the Cold Dark Matter paradigm?

, 2008
We study six groups and clusters of galaxies suggested in the literature to be `fossil' systems (i.e. to have luminous diffuse X-ray emission and a magnitude gap of at least 2 mag-R between the first and the second ranked member within half of the virial

Spalax denizliensis sp. nov. (Spalacidae, Rodentia) from an early Pleistocene-aged locality in the Denizli Basin (southwestern Turkey) [PDF]

, 2018
It is thought that Spalacidae (Rodentia, Mammalia) originated in Anatolia. They are widespread among Neogene-aged faunas in Anatolia and they are used as zonal fossils because of their strong evolutionary dynamics. Only one fossil species (S.

Submergence and uplift associated with the giant 1833 Sumatran subduction earthquake: Evidence from coral microatolls [PDF]

, 1999
The giant Sumatran subduction earthquake of 1833 appears as a large emergence event in fossil coral microatolls on the reefs of Sumatra's outer-arc ridge.

Suzaku Observations of the X-ray Brightest Fossil Group ESO 3060170

, 2013
"Fossil" galaxy groups, each dominated by a relatively isolated giant elliptical galaxy, have many properties intermediate between groups and clusters of galaxies.

Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

Advanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Fossilized bioelectric wire – the trace fossil Trichichnus [PDF]

Biogeosciences, 2014
Abstract. The trace fossil Trichichnus is proposed as an indicator of fossil bioelectric bacterial activity at the oxic–anoxic interface zone of marine sediments. This fulfils the idea that such processes, commonly found in the modern realm, should be also present in the geological past.

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
