Potassium Migration of Chestnut Shell Ashes Under Oxidizing Atmosphere and Its Modification Mechanism by Additives

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biomass energy plays a critical role in alleviating environmental pressures. However, its relatively high content of alkali metals (especially for potassium) would cause ash‐related issues during combustion. To mitigate these issues, the potassium migration behaviors during chestnut shell (CS) conversion and the modification mechanisms of ...

Carbonate Formation in Non-Aqueous Environments by Solid-Gas Carbonation of Silicates

, 2012
We have produced synthetic analogues of cosmic silicates using the Sol Gel method, producing amorphous silicates of composition Mg(x)Ca(1-x)SiO3. Using synchrotron X-ray powder diffraction on Beamline I11 at the Diamond Light Source, together with a ...

Processability and Crosslink Density: Role of Peptizers in Natural Rubber and Chlorobutyl Rubber

Journal of Applied Polymer Science, EarlyView.
This work evaluates how chemical and physical peptizers affect mastication, vulcanization behavior, and network formation in natural rubber and chlorobutyl rubber. Size‐exclusion chromatography, rheometry, DSC, and swelling analyses demonstrate improved processability but reduced crosslink density with peptizer addition.

Application of polystyrene sulfonates for the depression of magnesium-containing silicates in copper-nickel ore flotation

Горные науки и технологии
It is very urgent to increase the efficiency of depressing magnesium-containing silicates (MS) in the course of the flotation of copper-nickel ores to reduce the content of magnesium in the concentrate, which causes a significant increase in energy ...

A Near-Infrared Search for Silicates in Jovian Trojan Asteroids

, 2011
We obtained near-infrared (0.8 - 2.5 micron) spectra of seven Jovian Trojan asteroids that have been formerly reported to show silicate-like absorption features near 1 micron.

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Amorphous Protective Layers to Reshape Inorganic‐Rich Interphases for High‐Voltage Sodium‐Ion Batteries

Carbon Energy, EarlyView.
Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...

Evaluation of silicon, calcium and magnesium in liquid fertilizers on sorghum growth in the greenhouse

Agronomía Costarricense, 2015
The effect of liquid fertilizers with Si, Ca or Mg on the growth of sorghum (Sorghum bicolor) was evaluated in an Ultisol under greenhouse conditions. Four liquid fertilizers (two potassium silicates, calcium carbonate and magnesium oxide) were applied ...
