Development of a Novel Thermal Shock test for isostatically Pressed Carbon-Bonded Refractories
… and to quantify resulting damage in Alumina-Carbon-based mixes. This preliminary phase established that the test protocol can record strain evolution and the onset of cracking as function of time and temperature. Specimen geometries were designed to be representative of service pieces. In the …

Ultrasound Mediated Synthesis of Catalytic and Polymeric Materials
Polymer to diamond-like carbon. Synthesis of a carbon-based network polymer with an sp3 hybridized backbone which upon pyrolysis should yield a diamond-like carbon film. The rational design of an appropriate organic monomer and its polymerization to a network polymer whose weakest bond is between …

Thermochemistry and kinetics in pyrolysis and oxidation reaction of oxygenate chlorocarbons, neopentane, and ortho-xylene
… combustion or incineration of chlorinated hydrocarbons. The entropy and heat capacities from vibrational, translational, and external rotational contributions are calculated by statistical mechanics, and the hindered rotational contributions to S_{298} and C_p(T)'s are calculated by using direct …

Einfluss von Aluminiumoxid- und Titanoxid-Additiven auf die Thermoschockbeständigkeit von MgO-teilstabilisiertem Zirkonoxid
… whose porosity remains under the porosity of carbon bonded refractories, and thus possess the potential to process refractories with limited wall thickness. The thermal shock coefficients reflect the qualitative curve of fracture strength against the quenching temperature, but do not provide …

Formation of 2,5-trans-tetrahydrofuran-3-one application towards the synthesis of natural products
… the electrons of one of its d orbital to the carbon to form the metal carbenoid with elimination of nitrogen. Attack of one of the lone pair of the oxygen onto the carbon bonded to the 3 transition metal led to the formation of the oxonium ylide which undergoes [2,3]-sigmatropic rearrangement. …

Kohlenstoffgebundene Funktionalbauteile für die Metallurgie mittels kalt-isostatischem Pressen
Im Rahmen der vorliegenden Arbeit wurden neuartige keramik- und stahlreiche Verbundwerkstoffe, auf Basis von MgO-teilstabilisiertem Zirkoniumdioxid und hochlegiertem austenitischem TRIP Stahl entwickelt. Die keramikreiche Verbundwerkstoffe mit bis zu 30 Vol.% metallischer Partikelverstärkung wurden …

Non-stoichiometry and radiation damage effects in zirconium carbide and layered carbide ceramics for nuclear fuel cladding applications
… whose properties can be optimised by varying the carbon content. Whilst the majority of studies have focused on producing and measuring different properties of ZrC, very few studies have focused on accurately measuring the carbon content for a specified fabrication route resulting in a scatter in …
