An experimental study on the mix design optimization of fly ash-based geopolymers [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2019
Geopolymers are materials suitable for utilization in the construction industry due to their superior properties, such as high strength and good durability. The properties of geopolymers can be configured due to mix design and synthesis conditions.

Thermal stability and leaching behavior of alkali-activated slag doped with electric arc furnace dust [PDF]

open access: yesScience of Sintering
The study presented in this paper explores the simultaneous valorization of electric arc furnace slag (EAFS) and electric arc furnace dust (EAFD) through an alkali activation process, as well as the thermal stability of the resulting product.

Development of unfired earthen building materials using muscovite rich soils and alkali activators

open access: yesCase Studies in Construction Materials, 2019
Most studies have focused on the alkali activation of thermally activated kaolinitic clays for the production of innovative building materials. Whilst the widespread use of these minerals may be hindered due to geographical availability; a combination of

Co-Mn-Al mixed oxides promoted by K for direct NO decomposition: Effect of preparation parameters [PDF]

open access: yes, 2019
Fundamental research on direct NO decomposition is still needed for the design of a sufficiently active, stable and selective catalyst. Co-based mixed oxides promoted by alkali metals are promising catalysts for direct NO decomposition, but which ...

SMALL POLARONS IN REAL CRYSTALS - CONCEPTS AND PROBLEMS [PDF]

open access: yes, 2002
Much of small polaron theory is based on highly idealized models, often essentially a continuum description with a single vibrational frequency. These models ignore much of the wealth of experimental data, which find interpretation in many atomistic ...
