Summary: A new lanthanum sulfide nanoparticle was synthesized and incorporated onto magnetic graphene oxide sheets to create a potential adsorbent for efficient removal of lead ions from wastewater. The synthesized adsorbent was characterized and parameters such as pH, dosage, contact time, concentration, and temperature were studied. The Langmuir isotherm model showed the best fit with a maximum adsorption capacity of 123.46 mg/g, indicating a monolayer adsorption pattern. The pseudo-second-order kinetic model best described the adsorption rate, while the thermodynamic model suggested a chemisorption and physisorption adsorption mechanism at different temperatures.

Summary: In this study, bio-inspired urchin-like structured hydroxyapatite (UHdA) and its magnetic composite (UHdA@Fe3O4) were developed for efficient and easy separation of cerium ions (Ce3+) from aquatic waste streams. The adsorption of Ce3+ to UHdA and UHdA@Fe3O4 were found to be heterogeneous, pseudo-second order kinetic, with the rate-limiting step being external mass transfer and intra-particle diffusion. XRD, FTIR, and XPS analysis demonstrated that the adsorption was mainly attributable to the ion exchange of Ce3+ with Ca2+ and to surface complexation. The results suggest that UHdA and UHdA@Fe3O4 could be promising choices for the adsorption and recovery of rare earth elements.

Summary: In this study, two acrylate-modified hydrochars were synthesized by grafting acrylic acid onto the surface of hydrochars. The hydrochars used were carbonized in water and acidic medium, respectively. It was found that one of the hydrochars was more prone to free radical polymerization and had a higher carboxylate content after modification. The modified hydrochar showed higher adsorption capacity for methylene blue and lead ions. The adsorption mechanism involved complexation, ion exchange, electrostatic interaction, H-bonding, and p-p interaction. This study suggests that one-step modification method has great potential for preparing carboxylate-modified hydrochars for cationic pollutant adsorption.

Summary: Hydrogen-substituted graphdiyne (HsGDY) was successfully fabricated and employed as an effective adsorbent to remove lead ions from sewage and lead-containing blood. HsGDY exhibited a high adsorption capacity of lead, approximately five times larger than that of graphdiyne (GDY), due to its unique hexagonal hole and stack mode that allows for more lead adsorption. The strong bonding of lead atom on HsGDY and the easy regeneration process further enhance its performance as a promising adsorbent for lead removal.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
