Clinical outcomes of a novel flowable calcium silicate cement in equine endodontic treatment

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Orthograde endodontic treatment of equine cheek teeth is performed infrequently with variable success rates of obturation with calcium hydroxide paste (CHP). A novel flowable calcium silicate cement (eCSC) formulated for use as an obturation material in equine teeth has demonstrated acceptable canal filling volumes and evidence of ...

Investigation of Systematic Discrepancies Between MCC and TGA Measurements Affecting the Determination of Heat of Combustion

open access: yesFire and Materials, EarlyView.
ABSTRACT The determination of step‐resolved effective heats of combustion is essential for detailed pyrolysis modelling in fire growth and flame spread predictions, especially in multi‐step processes where the heat of combustion can differ between reaction steps.

Architecting nano‐Al/HMX/CuO energetic micro‐units unlocks superior interface and highly efficient combustion

open access: yesInfoMat, EarlyView.
Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

Mechanical Behavior of Reactive Powder Concrete with Glass Powder Substitute

open access: yesProcedia Engineering, 2015
AbstractAs reported in literature, the Reactive Powder Concrete (RPC) with quartz powder substitute has a high compressive strength of 180MPa and has a fairly high tensile strength. That research used the RPC with quartz powder to cement ratio of 30% and steam curing technique in an autoclave temperature of 250°C.

On the incorporation of waste ceramic powder into concrete

open access: yes
This study investigates the potential use of waste ceramic powder as a filler in concrete. Different percentages of waste ceramic powder were added to the concrete, and the compressive strength and water absorption properties were assessed.
