Impact of Nano-Cr2O3 Addition on the Properties of Aluminous Cements Containing Spinel

Medžiagotyra, 2015
In this paper, the effect of nano-Cr2O3 addition on the properties of aluminous cement containing MgAl2O4 spinel was investigated. For this reason, the raw dolomite was used as raw material along with calcined alumina for the preparation of the aluminous

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

Surface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification

Pulse Electrodeposited NiFeCoMoW High‐Entropy Alloy Electrode for Efficient Alkaline Water Electrolysis

Small, EarlyView.
A pulse‐electrodeposited NiFeCoMoW high‐entropy alloy grown on copper foam forms a binder‐free, hierarchical electrode for alkaline water splitting. The bifunctional catalyst achieves low overpotentials for hydrogen and oxygen evolution and enables efficient two‐electrode electrolysis, delivering 1.52 V at 10 mA cm−2 and 1.83 V at 1000 mA cm−2.

The effect of microsilica and refractory cement content on the properties of andalusite based Low Cement Castables used in aluminum casthouse O efeito do teor de microsílica e de cimento refratário nas propriedades de LCCs usados em moldagem de alumínio

Cerâmica, 2010
The bonding system in low cement castables is achieved by the use of calcium aluminate cement, microsilica and reactive alumina. The lime/silica ratio critically impacts the liquid phase formation at high temperatures and subsequently the corrosion ...

Spatiotemporal Co‐Delivery of Hydrogen and Magnesium via Microneedle Patches for Neuroinflammation Modulation After Spinal Cord Injury: A Multi‐Modal In Vivo Study

Small, EarlyView.
A spatiotemporal co‐delivery microneedle system (MN‐Mg) is developed for spinal cord injury repair. By generating hydrogen gas and magnesium ions in situ, this dual‐engine platform effectively scavenges ROS and modulates microglial polarization via the MAPK/AP‐1 signaling axis.

Effect of Prewetting Cenospheres on Hydration Kinetics, Microstructure, and Mechanical Properties of Refractory Castables

Crystals
This study investigated the effect of non-prewetted and prewetted cenospheres (CSs) on the hydration course and physical and mechanical properties of refractory castable mixtures incorporated with nano silica (NS). The fixed amount of 0.1% of NS improves
