In order to improve the anti-seepage performance of cover, this paper proposed use super absorbent polymer (SAP) particles water storage capacity soil, and mixed them into soil build an SAP composite but law movement in which is not clear. paper, a series column model tests were carried out measure changes pore pressure volume content cover at different depths. The results showed that under ext...

A new composite absorbent with multifunctional and environmental-friendly structures was prepared using chitosan, diatomite and polyvinyl alcohol as the raw materials, and glutaraldehyde as a cross-linking agent. The structure and morphology of the composite absorbent, and its adsorption properties of Hg(II) in water were characterized with Fourier transform infrared (FT-IR) spectra, scanning e...

Superabsorbent polymers (SAPs) are functional macromolecules with high water absorption and retention capacities. Nowadays, carboxymethyl cellulose (CMC) nanofibrils (CMCNFs) widely utilized as absorbent materials to replace petroleum-based SAPs, which lead environmental pollution. However, their water- holding characteristics inferior compared those of SAPs. In this study, we explore the polym...

Antimicrobial surfaces can be applied to break transmission pathways in hospitals. Polyaniline (PANI) and poly(3-aminobenzoic acid) (P3ABA) are novel antimicrobial agents with potential as non-leaching additives to provide contamination resistant surfaces. The activity of PANI and P3ABA were investigated in suspension and as part of absorbent and non-absorbent surfaces. The effect of inoculum s...

The effect of bio-fertilizers and super-absorbents on the modification water-deficit stress was studied in castor. A field experiment conducted with a split-plot design based completely randomized block three replications. first factor included four levels (70, 100, 130, 160 mm evaporation pan Class) main plot; sub-factor application bio-fertilizer treatments (Azospirillum, Citrobacter, Azospir...

A new biomimetic absorbent, cellulose acetate (CA) embedded with triolein (CA-triolein), was prepared and applied for the removal of persistent organic pollutants (POPs) from micro-polluted aqueous solution. The comparison of CA-triolein, CA and granular activated carbon (GAC) for dieldrin removal was investigated. Results showed that CA-triolein absorbent gave a lowest residual concentration a...

It is imperative to develop organ manufacturing technologies based on the high organ failure mortality and serious donor shortage problems. As an emerging and promising technology, bioprinting has attracted more and more attention with its super precision, easy reproduction, fast manipulation and advantages in many hot research areas, such as tissue engineering, organ manufacturing, and drug sc...
