ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior

ChemistryOpen, EarlyView.
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...

Interaction of fibrinogen with nanosilica

Open Chemistry, 2007
AbstractInteraction of human plasma fibrinogen (HPF) with fumed nanosilica A-300 in a phosphate buffer solution (PBS) was studied using 1H NMR spectroscopy with layer-by-layer freezing-out of bulk and interfacial water in the temperature range of 210–273 K, TSDC (90 T FTIR, and UV spectroscopy methods.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Nanosilica Modifiers for Cement Mortars

Procedia Engineering, 2016
AbstractMan-made products containing 95…96% of amorphous nanostructured silica were studied for the purpose of their usage as modifiers for cement mortars. These products are “belaya sazha (carbon white)” BS120 (BS) obtained by means of hydrochemical synthesis and amorphous silicon dioxide (ADK) produced from rice husk being thermally treated at 800 оС.
