Cytotoxicity and Bone Biocompatibility of the C-Root SP Experimental Root Canal Sealer.

This study evaluated the cytotoxicity and biocompatibility of a new strontium silicate-based root canal sealer (C-Root SP), in comparison with those of iRoot SP and AH plus. The sealer extract was diluted to the concentrations of 100%, 75%, 50%, and 25%. L929 cells were cultured for 24 h, and the absorbance value was determined.

Minimum wages and alcohol consumption: Evidence from Canadian longitudinal microdata.

Objective: The objective is to estimate the effect of provincial minimum wage increases in Canada on heavy drinking, binge drinking and average daily alcohol consumption.

Method: We estimate standard regression models by gender-age group with drinking behaviours as the dependent variables and the minimum wage among the independent variables. We employ the Canadian National Population Health Survey which began in 1994 and ended in 2011, a period comparable to that used by many U.

Bubble Nucleation and Heat Transfer on Three-Dimensional Mixed-Wettable Nanostructured Surfaces: A Molecular Dynamics Study.

This study explores the bubble nucleation process and heat transfer characteristics on nanostructured solid surfaces with mixed-wettable pillars using molecular dynamics simulations. Five different surfaces were designed by varying the wettability of the central pillars while keeping the lateral pillars hydrophilic. The nucleation behavior of argon bubbles was observed to differ significantly across these surfaces due to the combined effects of nanostructuring and mixed wettability.

Oscillatory Motion of a Camphor Disk on a Water Phase with an Ionic Liquid Sensitive to Transition Metal Ions.

We investigated oscillatory motion of a camphor disk floating on water containing 5 mM hexylethylenediaminium trifluoroacetate (HHexen-TFA) as an ionic liquid (IL). The frequency of the oscillatory motion increased with increasing concentrations of the transition metal ions Cu and Ni but was insensitive to Na, Ca, and Mg, the typical metal ions in the water phase. The surface tension of the water phase containing 5 mM HHexen-TFA also increased with increasing concentrations of Cu and Ni but was insensitive to Na, Ca, and Mg.

Super Tough Multifunctional MXene/PAA-CS Double Network Hydrogels with High Mechanical Sensing Properties and Excellent EMI Shielding Performance.

Hydrogels present significant potential in flexible materials designed for electromagnetic interference (EMI) shielding, attributed to their soft, stretchable mechanical properties and water-rich porous structures. Unfortunately, EMI shielding hydrogels commonly suffer from low mechanical properties, deficient fracture energy, and low strength, which limit the serviceability of these materials in complex mechanical environments. In this study, the double network strategy is successfully utilized along with the Hofmeister effect to create MXene/PAA (polyacrylic acid)-CS (chitosan) hydrogels and further strengthen and toughen the gel with (NH)SO solution.
