Article Synopsis
- The study investigates the mechanical strength of fetal membranes in women at risk for preterm premature rupture of membranes (PPROM) through a series of tensile tests on tissue samples collected from pregnant women undergoing cesarean sections.
- Results indicate that first-time mothers (primiparous) have weaker fetal membranes compared to those with previous births, while factors like gestational diabetes and geographic origin affect membrane properties such as thickness and mechanical strength.
- Overall, thicker membranes show decreased rigidity and resistance, highlighting the complex interplay between various risk factors and membrane integrity in pregnancy.
Hypotheses: The present work aims at investigating the effect of pH values and additives on the dispersion of two 1:1 dioctahedral phyllosilicates in the presence of water. Two model clays are used for this purpose, BIP kaolin and NZCC halloysite, presenting the same surface chemistry but different morphologies. The effect of sodium hexametaphosphate, sodium silicate and sodium carbonate is discussed.

- * Chitosan concentration was found to significantly affect the foam's morphology, impacting the arrangement of pores and the foams' density and thermal conductivity.
- * While these chitosan-based biofoams show promising insulation properties, they are less durable in wet conditions, prompting researchers to explore the creation of a ceramic material with open porosity by using an organic solvent to infiltrate the foam.
