  The primary purpose of this study is to produce a composite scaffold using polycaprolactone (PCL) and heparinized nano-fluorohydroxyapatite for cancellous bone tissue engineering. The research investigated the impact of heparinized nano-fluorohydroxyapatite particles on various properties of the scaffold, including water absorption, biodegradability, and alkaline phosphatase activity. The scaffold was produced using the phase separation (solid-liquid) method in combination with freeze-drying, and two different concentrations of heparinized nano-fluorohydroxyapatite powder were utilized. Biodegradability was assessed by submerging the scaffolds in phosphate-buffered saline for 6 weeks, showing that increased nano-fluorohydroxyapatite content enhanced biodegradability. PCL/10%w(H-nFHA50) exhibited the highest biodegradability rate. Water absorption analysis revealed that PCL scaffolds had lower water absorption compared to composite samples with heparinized nano-fluorohydroxyapatite, with PCL/10%(H-nFHA50) demonstrating the highest water absorption. Alkaline phosphatase activity was assessed on day 14 of cell culture, showing higher activity in heparinized samples compared to heparin-free samples in the presence of nano-fluorohydroxyapatite. The presence of heparin and nano-fluorohydroxyapatite in the scaffold structure likely contributed to this difference. No significant difference was observed between heparinized scaffolds with different nano-fluorohydroxyapatite concentrations. The results emphasize that the constructed scaffolds possess the potential for utilization in cancellous bone tissue engineering. Manuscript profile

  Pervious concrete is a special type of lightweight concrete with low or even zero slump, which consists of cement, coarse aggregate, a limited percentage of fine aggregate (or no fine aggregate), various chemical and pozzolanic additives. In this article, structural LECA with a volumetric weight of 750 kg/m3 and a fixed water-to-cement ratio (W/C = 0.3) was used to make lightweight pervious concrete and the effect of different ratios of lightweight aggregate to cement (A/C) including 1.5, 1.8, 2.1, 2.4, 2.7, 3, total porosity and volume percentage of cement paste on compressive strength , specific electrical resistance and percentage of water absorption of lightweight pervious concrete aged 28 days were investigated. With the increase of A/C ratio from 1.5 to 3, the volume of cement paste decreased from 30.873% to 15.436% in the samples and the total porosity increased from 21.64% to 38.08%, which led to a decrease Specific electrical resistance decreased from 11.45 to 6.841 , compressive strength decreased from 13.27 MPa to 4.37 MPa, and water absorption increased from 11.185% to 12.695% in lightweight pervious concrete samples. The results of this research showed the improvement of physical properties and the decrease of mechanical properties and durability of lightweight pervious concrete containing LECA.
