Summary: The physical and surface properties of sodium tripolyphosphate (TPP) and vanillin (V)-modified chitosan-based magnetic nano-sorbents (TPP-CMN and V-CMN) were characterized. FE-SEM and XRD analysis showed the average size of Fe3O4 magnetic nanoparticles between 6.50 and 17.61 nm. The TPP-CMN and V-CMN nano-sorbents exhibited high sorption capacity for heavy metal ions. The synthesis of these nano-sorbents and their efficient and cost-effective performance in wastewater treatment make them highly valuable. Rating: 8/10.

Summary: Aminopyridine functionalized Fe3O4 nanocomposites were prepared and used as adsorbents for removing Cd(II) and Ni(II) from water. The adsorption process was found to be influenced by factors such as pH, concentration, and temperature, with the optimal conditions at pH 6 and saturation achieved in 270 and 260 minutes. Kinetics were controlled by film diffusion and followed a pseudo-second-order model, while the adsorption mechanism involved a synergistic effect of nitrogen atoms from aminopyridine group. The nanocomposites showed good regeneration performance.

Summary: A Fe3O4 decorated attapulgite adsorbent (FA) was prepared for Cd(II) removal from wastewater, which was later turned into a CdS/FA photocatalyst. With in situ growth of Fe3O4 on attapulgite, the FA adsorbents showed increased surface area and improved adsorption sites. Strong interaction between Fe3O4 and ATP resulted in enhanced adsorption performance for Cd(II). The waste FA adsorbent could be easily separated and converted into a CdS/FA photocatalyst, displaying satisfying degradation efficiency for tetracycline.

Summary: The crystallographic orientation dependence of nanopattern morphology and size of electropolished Al at a fixed voltage (40 V) has been revealed and established. However, systematic experimental studies on the effects of voltage on nanopattern morphology and size with samples' crystallographic orientation exactly determined have been lacking. This study investigates the voltage and crystallographic orientation dependence of nanopattern morphology and size by electropolishing miscut monocrystalline Al samples at voltages 20-60 V. The findings reveal the emergence of various nanopatterns with distinct morphologies and explain the gradual transformation of morphologies with misorientation angle from the perspective of surface structure sensitivity. Additionally, the study uncovers the voltage dependence of nanopattern size and reexamines a reported model to explain the observed dependence.

Summary: The article investigates the role of single-layer graphene in the oxidation process of Cu substrates and reports the evolution of interfacial oxide layers of graphene/Cu samples over time. ARXPS study reveals that the thickness of the interfacial oxide layer is positively correlated with air exposure time, and the fractional coverage of the island-like interfacial oxide layer is in the range of 0.4-0.6. For graphene/Cu samples exposed to ambient conditions for less than 6 months, graphene can inhibit the formation of Cu2O, whereas it promotes the formation of CuO in the interfacial oxide layer for long-term oxidized graphene/Cu samples (>= 12 months), resulting in an embedded structure of the interfacial oxide layer. These findings can guide the corrosion protection of copper-based devices.
