Summary: Phosphorylation of cellulose using environmentally friendly chemicals leads to a negatively charged material with high adsorption capacity for methylene blue in water purification. Different cellulose sources exhibit varying degrees of functionalization and methylene blue removal efficiency, with wood cellulose showing the highest phosphorylation degree and adsorption properties. The possibility of regenerating the used sorbent by washing it with phosphate ions is demonstrated with a 97% regeneration rate.

Summary: Environmentally friendly crosslinked carboxymethyl cellulose-based hybrid hydrogels (CCMC/OMMT) with a grafting of 2-acrylamide-2-methylpropane sulfonic acid (AMPS) onto CCMC and reinforced with Organo-Montmorillonite (OMMT) were developed as efficient adsorbents for methylene blue (MB). Various techniques including FTIR, SEM, XRD, EDS, XPS, and TGA were used to analyze the composition and shape of the hydrogels. The adsorption capacity of CCMC/OMMT for MB was found to be 490.5 mg/g at 313.15 K and pH 7.0. The adsorption kinetics and isotherm were successfully described by the pseudo-second-order dynamic theory and Langmuir isotherm theory. The results indicated that the binding of MB on CCMC/OMMT was spontaneous and endothermic, facilitated by electrostatic attraction and hydrogen-bonding interaction. Moreover, the hydrogels exhibited reusability for MB removal.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
