“…In addition to CBB G250, other dye molecules were also used to explore the ion sieving mechanism of GO membranes, including negatively charged Congo red (CR, M w = 696.66, size: 28.9 × 10.5 × 5.5 Å), acid fuchsin (AF, M w = 585.55, size: 14.7 × 13.8 × 8.7 Å), and methyl orange (MO, M w = 327.35, size: 17.8 × 7.3 × 6.6 Å) and positively charged rhodamine B (RB, M w = 479.02, size: 17.5 × 14.9 × 7.9 Å) and methylene blue (MLB, M w = 373.90, size: 17.4 × 8.2 × 4.3 Å). − They were dissolved in deionized water to form a 10 mg L –1 solution. For the negatively charged dyes (CBB G250, CR, AF, and MO), the retention rate is closely related to the M w (i.e., size) of dyes with a molecular weight cutoff of 600–700 Da (Figure c); the larger the M w , the higher the retention rate, and vice versa .…”

The surface properties and microstructure of graphene oxide (GO)-based membranes are both crucial for enhanced nanofiltration performance. Herein, a GO nanofiltration membrane is fabricated with regulatable surface properties and microstructure via a facile two-step impregnation in KOH and following HCl aqueous solutions. The type and number of oxygen-containing groups in GO membranes change with fewer C−O−C/C−OH and C�O but more COOH groups, and they are readily regulated by alkaline treatment time, which enables enhanced surface hydrophilicity and larger surface ζ potentials. Meanwhile, a few tiny defects are present in the GO sheets, which could increase the number of pores and decrease the length of water nanochannels. Such surface properties and microstructure together determine the excellent nanofiltration performance of the GO membranes with fast and selective water permeation, e.g., ∼99.5% rejection toward CBB G250 and flux of 56.9 ± 1.0 L m −2 h −1 . This work provides insights into the design of high-performance two-dimensional laminar membranes.

“…Besides, NLO materials have applications in sorely fast optical modulation and switching 22 . The most popular method for determining the NLO properties in materials includes Z-scan 23 , I-scan 24 , and two-beam coupling 25 . Compared with other methods, Z-scan was widely used because of its high sensitivity and simplicity 26 .…”

A new series of Cu (II) complexes were prepared using Schiff base ligand of N–N′-(1,2-diphenyl ethane-1,2-diylidene)bis(3-Nitrobenzohydrazide). The prepared ligand and Cu (II) complex were characterized using various physicochemical investigations such as X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), and Energy dispersive X-ray analysis (EDX), Fourier Transform Infrared (FT-IR), $${}^{13}C$$ 13 C Nuclear Magnetic Resonance (NMR), $${}^{1}H$$ 1 H NMR, Diffuse Reflectance Spectroscopy (DRS), Vibrating Sample Magnetometer (VSM), and Z-Scan technique (Nonlinear optical (NLO) properties). In addition, the prepared samples have been examined for their NLO characteristics with the help of the Density Functional Theory calculations which proved that the Cu (II) Complex is more polarized than Ligand. According to XRD and FESEM results, the nanocrystalline nature of the samples is confirmed. The metal-oxide bond assigned in the functional studies by FTIR. Magnetic studies demonstrate weak ferromagnetic and paramagnetic nature for Cu (II) complex and diamagnetic nature for the ligand, respectively. DRS spectrum exhibited higher reflectance for Cu (II) than the ligand. The band gap energies of the synthesized samples were estimated by employing the Tauc relation and Kubelka–Munk theory on reflectance data and found to be 2.89 eV and 2.67 eV for Cu (II) complex and ligand, respectively. Extinction coefficient and refractive index values were calculated using the Kramers–Kronig method. The z-scan technique was applied to estimate the NLO properties by a 532 nm Nd:YAG laser.
