Preparation and characterization of poly(Bisphenol A-Phthalate) and its metal removal behavior toward Pb(II), Cu(II), and Cd(II) ions

Sustainable Environment
The polymer poly(BPA-phthalate) (BPA-PHTH) was synthesized from BPA and phthaloyl dichloride by using interfacial condensation polymerization. The prepared polymer was characterized using (FTIR,1H-NMR, 13C-NMR, DSC, TGA, SEM, and polymer solution ...

Abiotic and Biotic Factors Influencing the Effect of Microplastic on Soil Aggregation

Soil Systems, 2019
Plastic is an anthropogenic, ubiquitous and persistent contaminant accumulating in our environment. The consequences of the presence of plastics for soils, including soil biota and the processes they drive, are largely unknown.

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
