TL;DR: In this paper, a meso-porous molecular sieve catalyst with carbide features that the carbide particles are assembled in the pores of the sieve, resulting in high isolation and dispersion of active component particles and in turn high stability and activity.

TL;DR: In this article, an extensive presence of intermetallic phases was observed in the cast products, as a result of both the inoculation by K 2 TiF 6 and the intensive reactivity of the carbides with the molten matrix.

22 Nov 2005TL;DR: In this article, the authors provide tools for growing conformal metal thin films, including metal nitride, metal carbide and metal nithide carbide, from aggressive chemicals.
Abstract: The present methods provide tools for growing conformal metal thin films, including metal nitride, metal carbide and metal nitride carbide thin films. In particular, methods are provided for growing such films from aggressive chemicals. The amount of corrosive chemical compounds, such as hydrogen halides, is reduced during the deposition of transition metal, transition metal carbide, transition metal nitride and transition metal nitride carbide thin films on various surfaces, such as metals and oxides. Getter compounds protect surfaces sensitive to hydrogen halides and ammonium halides, such as aluminum, copper, silicon oxide and the layers being deposited, against corrosion. Nanolaminate structures incorporating metallic thin films, and methods for forming the same, are also disclosed.

TL;DR: In this paper, a photoemission and x-ray-absorption study on boron carbide is presented, which identifies the spectroscopic features of this material, discussing them in connection with current structural models.
Abstract: We present a photoemission and x-ray-absorption study on boron carbide which identifies the spectroscopic features of this material, discussing them in connection with current structural models. A study on the surface thermal stability is also performed, revealing that despite the high melting point of boron carbide $(\ensuremath{\sim}2600\mathrm{K}),$ significant surface modifications occur in the material at about 1800 K. At this temperature the surface becomes covered with a graphite layer formed from bulk segregation of carbon, leaving boron-rich boron carbide buried beneath the graphitic surface.

TL;DR: A hierarchical and highly porous carbide-derived carbon (CDC) was obtained by nanocasting of pre-ceramic precursors into cubic ordered silica (KIT-6) and subsequent chlorination.
