Effects of alloy elements on ductility and thermal conductivity of compacted graphite iron [PDF]
China Foundry, 2018 The influence of Si, Sn, Mo and Ni on the ductility and thermal conductivity of compacted graphite iron (CGI) was investigated. Metallographic observation and Differential Scanning Calorimetry (DSC) experiments were carried out to analyze the roles of ...

Ferromagnetism of a graphite nodule from the Canyon Diablo meteorite [PDF]
Nature 420, 156 - 159 (2002); doi:10.1038/nature01100, 2002 There have recently been various reports of weak ferromagnetism in graphite (1,2) and synthetic carbon materials (3) such as rhombohedral C60 (4), as well as a theoretical prediction of a ferromagnetic instability in graphene sheets (5). With very small ferromagnetic signals, it is difficult to be certain that the origin is intrinsic, rather than due ...

Some paradoxical observations about spheroidal graphite degeneracy [PDF]
China Foundry, 2018 Differential thermal analysis experiments have been performed on samples machined from Y2-blocks cast with different high-silicon spheroidal graphite irons. Depending on magnesium, silicon, cerium and antimony content, the as-cast microstructure showed

They Came From the Deep in the Supernova: The Origin of TiC and Metal Subgrains in Presolar Graphite Grains [PDF]
Astrophys.J.647:L37-L40,2006, 2006 A new formation scenario for TiC and Fe,Ni-metal inclusions in presolar graphite grains of supernova origin is described. The mineralogy and chemistry require condensation of (Fe,Ni)-titanides from Fe, Ni, and Ti-rich gaseous ejecta, subsequent carburization to make TiC and metal, and encapsulation into graphite.

Aggregate, Volume 3, Issue 6, December 2022., 2022 Carbon dots (CDs) has excellent photoluminescence properties. Aggregation plays an important role in both the formation of CDs and their fluorescence, yet is seldom studied in detail. This review aims to fill this knowledge gap. We first discuss how aggregation leads to the formation of different types of CDs, and the impact on morphology, luminescence,

Infrared emission towards 11 years after outburst: Properties of the circumstellar dust [PDF]
Astron.Astrophys.395:189,2002, 2003 Detailed models are presented for the late epoch mid infrared (MIR) emission from collisionally heated grains in the shocked circumstellar gas around SN 1987A. Thermal dust emission from a region of moderate density interior to the thick inner ring seen with the Hubble Space Telescope (HST) is found to be a natural explanation for the MIR spectral ...
