Textile wastewater accommodates many toxic organic contaminants that could potentially threaten the ecosystem if left untreated. Methylene blue is a toxic, non-biodegradable, cationic dye that is reportedly observed in significant amounts in the textile effluent stream as it is widely used to dye silk and cotton fabrics. Congo red is a carcinogenic anionic dye commonly used in the textile industry. This study reports an investigation of methylene blue and Congo red removal using a chitosan-graphene oxide dip-coated electrospun nanofiber membrane. The fabricated nanocomposite was characterized using Scanning Electron Microscopy (SEM), FT-IR Spectroscopy, Raman Spectroscopy, UV-vis Spectroscopy, Drop Shape Analyzer, and X-ray Diffraction. The isotherm modeling confirmed a maximum adsorptive capacity of 201 mg/g for methylene blue and 152 mg/g for Congo red, which were well fitted with a Langmuir isotherm model indicating homogenous monolayer adsorption.

Microspore culture is an efficient and rapid method that produces doubled haploid (DH) lines for hybrid breeding in crops and vegetables. However, the low frequency of microspore embryogenesis and spontaneous diploidization in Chinese kale still require improvement. In the present work, an efficient microspore culture protocol was constructed and used for DH producing in Chinese kale breeding.

This study investigates the synthesis, characterization, and functional properties of well-aligned zinc oxide (ZnO) nanowires (NWs) obtained by a two-step hydrothermal method. ZnO NWs were grown on silicon substrates precoated with a ZnO seed layer. The growth process was conducted at 90 °C for different durations (2, 3, and 4 h) to examine the time-dependent evolution of the nanowire properties.

Background Ureterovaginal fistulae usually follow iatrogenic injury to the ureter during pelvic surgery. This manifests as urine incontinence and results in serious psychosocial effects on women. Ureterovaginal fistulae unlike vesicovaginal fistulae present challenges in diagnosis and management especially in resource-constrained settings.

The current work focused on the synthesis of C/N-co-doped-ZnO nanorods a facile, eco-friendly, and solvent-free mechano-thermal approach. The synthesized C/N-co-doped ZnO nanorods were employed for the photocatalytic decay of methylene blue (MB) and brilliant cresyl blue (BCB) dyes, and their degradation capability was compared with that of pure ZnO nanoparticles prepared a precipitation approach.

Background: Accurate localization of small pulmonary nodules (SPNs) during video-assisted thoracoscopic surgery (VATS) is challenging due to the small size and deep location. Both the 4-hook wire technique and methylene blue are significant methods for preoperative localization of SPNs. This study aimed to compare the safety of both methods by monitoring and recording any surgery-related complications.
