Ellipsoidal hollow nanostructures assembled from anatase TiO(2) nanosheets as a magnetically separable photocatalyst
No full textA simple approach was proposed to synthesize three types of ellipsoidal hollow nanostructures whose shells are assembled from anatase TiO₂ nanosheets (NSs) with exposed (001) facets. Among them, ellipsoid Fe₃O₄@TiO₂-NS nanorattles can be readily generated as a magnetically separable photocatalyst with enhanced activity through in situ reduction of the α-Fe₂O₃ core.Jun Song Chen, Chunping Chen, Jian Liu, Rong Xu, Shi Zhang Qiao and Xiong Wen Lo
Waste-to-wealth: biowaste valorization into valuable bio(nano)materials
No full textThe waste-to-wealth concept aims to promote a future sustainable lifestyle where waste valorization is seen not only for its intrinsic benefits to the environment but also to develop new technologies, livelihoods and jobs. Based on the concept of waste valorization and circular economy, this review aims to provide an overview of present trends and future potential in the conversion of residues from different food sectors into valuable bio(nano)material
Melamine sponge loading improves the separation performance of magnetic hydroxyapatite for Pb(Ⅱ) adsorption
No full textMagnetic materials as adsorbents for wastewater treatment have attracted considerable attention because of the ease of separation of adsorbents for reuse. However, the efficient separation of magnetic materials, particularly nanoscale materials, remains challenging. Therefore, in this study, we developed an innovative method to enhance the separation performance of magnetic hydroxyapatite (MP) using melamine sponge (MS) loading. It was found that, although the magnetic moments of MP decreased from 15.54 emu/g to 11.51 emu/g after MS loading, MS-loaded MP (MPMS) exhibited better magnetic separation performance than MP. The analysis of adsorption isotherms suggests that the theoretical maximum adsorption capacity of Pb2+ at an initial pH of 4.85 using MPMS was 139.28 mg/g. Combined with adsorption kinetics and thermodynamics analysis, adsorption was categorized as a chemical, heterogeneous, and endothermic process. Moreover, in the adsorption mechanism, cation exchange, electrostatic interaction, dissolution/precipitation, and surface complexation mechanisms contributed 70.96%, 4.39%, 6.10%, and 18.55%, respectively, to the total Pb2+ removal under the experimental conditions. Hence, we provide a quick and low-cost solution for enhancing the downstream separation of magnetic adsorbents for reuse

Polyurethane sponge loading improves the suspension of magnetic materials without affecting the Pb(Ⅱ) adsorption
No full textMagnetic adsorbents are promising for wastewater treatment due to their easy separation with a magnetic field for recycling. This study aims to develop a novel magnetic adsorbent to further simplify the separation of magnetic adsorbents after adsorption to reduce operating costs for magnetic separation process. Thus, a lightweight sponge, magnetic hydroxyapatite modified polyurethane sponge (MPPS), was synthesized for Pb2+ adsorption by combining polyurethane sponge with magnetic hydroxyapatite (MP). The density of MP was about 4.23 g/cm3, while MPPS was only 0.46 g/cm3. As such, MP can float under the water surface, which is beneficial to the separation and Pb2+ adsorption in solutions. Meanwhile, the loading rate of MP on MPPS can reach 37.5%, and the loading process had no obvious effect on the physical and chemical properties of MP. Through experiments and characterization, MPPS had 60.46 mg/g adsorption capacity for Pb2+ in the solution with a pH of 5, and the adsorption was identified as a mainly homogeneous and exothermic process. Moreover, the adsorption of Pb2+ by MPPS was mainly due to the electrostatic interaction and ion exchange, accounting for 51.60% and 24.31% of the total adsorption, respectively. This study developed a lightweight magnetic sponge, which could be easier used in the magnetic separation process than conventional magnetic materials
Vibrationally Excited Level Identification and FIR Laser Line Prediction by the "Ritz" and "LaseRitz" Programs

Moruzzi and Li-Hong Xu, Ohio State University 49th International Symposium on Molecular Spectroscopy, TD04, p. 122 (1994).Author Institution: Università di Pisa, Piazza Torricelli 2, I-56100 Pisa, Italy; National Institute of Standards and Technology, Gaithersburg, MD 20899 U.S.A.Following last year's Columbus , we have continued our work on an interactive computer program for automating assignment of the Fourier-Transform methanol spectrum. Two new features have been developed. (1) A new routine has been incorporated in the Ritz program for the identification of small-amplitude vibrationally excited levels starting from the known energies of the ground-vibrational levels. We have been testing this routine in the region for . (2)A new LaseRitz program has been written for predicting FIR laser lines using known energies of the ground and the vibrationally excited levels. The simplified float chart of the interactive program is presented below
