Abstract:

Dyes represent one of the persistent pollutants, which are difficult to remove from wastewater by the conventional treatment methods. Low cost adsorbents prepared from tire rubber waste were used to remove cresol red dye from liquid solution. In order to save energy no agitation or activation were made on the adsorption process. This will naturally slow down the process, but time was compared to cost. The adsorbent weight, particle diameter and duration time were explored to measure the effectiveness of these parameters on adsorption rate. The best removal reached more than 81% at adsorbent we

Abstract:

Herein, a heterogeneous Fenton-like catalyst was designed by immobilizing iron oxide (FeS) and nickel sulfide (NiS) on the surface of β-cyclodextrin (β-CD), creating a NiS/FeS@β-CD composite for degrading triphenylmethane cresol red dye. Varied instruments were used to study the physical and chemical characteristics of the NiS/FeS@β-CD catalyst. The appropriate catalytic conditions of the Fenton-like degradation of cresol red by NiS/FeS@β-CD were identified, clarifying that the higher degradation % fulfilled 99.86% with an adsorption % of 27.44% at a cresol red concentration = 50 mg/L, NiS/FeS

Abstract:

The utilization of less expensive and more effective adsorbents derived from a variety of basic materials has been investigated. The research aimed to investigate the feasibility of employing waste paper as the adsorbent to remove the cresol red (CR) dye from wastewater through adsorption mechanism. Langmuir, Jovanovic, and Freundlich model were observed for isotherms models, while pseudo-first-order and pseudo-second-order were examined for kinetic models. The results indicated that increasing the adsorbent dose and contact time gave no significant effect to adsorption capacity while adsorpti

Abstract:

The present work focuses on the investigation of protective coatings produced on zinc from chitosan (Chit) and an anionic dye, namely cresol red. Cresol red (CR) fulfills the basic requirements to be used as a corrosion inhibitor because it possesses a relatively high molecular weight and includes in its structure oxygen and sulfur atoms as well as aromatic rings. Moreover, it is an anionic compound that can interact with positively charged chitosan to produce reinforced coatings for zinc anti-corrosion protection.

Experimental CKD leads to accumulation of uremic toxins (UT) in the circulation resulting in increased ROS production, which in turn, is known to activate the Na/K-ATPase/ROS amplification loop. Studies in a murine model of obesity have shown that increased oxidative stress in plasma is due to increased ROS and cytokine production from dysfunctional adipocytes. Therefore, we hypothesized that adipocytes exposed to UTs will activate the Na/K-ATPase oxidant amplification loop causing redox imbalance a

AbstractThe present study aimed to investigate the decolorization of various commercial dyes by azoreductases (AzrBmH21, AzrBmH22/3, and AzrBmH24/5) through bioinformatics means, comprising molecular docking, molecular dynamics simulation, and molecular mechanics Poisson–Boltzmann surface area (MM-PBSA). Therefore, four commercial dyes, namely acid orange 7, cresol red, methylene blue, and malachite green, were selected as potential targets for degradation by the above said azoreductases derived from Bacillus megaterium H2. The prediction of ligand binding or catalytic sites for AzrBmH21, AzrB

Abstract:

AbstractBistable electrochromic displays offer great potential due to their ability to maintain both colored and colorless states while minimizing power consumption and saving energy. In this research, the electrochromic properties of organic small molecular leuco dyes are explored. Various displays are fabricated using crystal violet lactone, cresol red, fluorescein, and rhodamine b derivatives, based on the proton‐coupled electron transfer mechanism. Considering the switching time and bistability, prototype devices such as anti‐counterfeiting displays, gate displays, e‐papers, multi‐color di

Abstract:

Abstract Para-cresol sulfate (PCS), a protein-bound uremic toxin, is a gut microbiota derived metabolite known for its role in human physiology and pathology. After PCS formation, it enters the blood stream and interacts with serum albumin with high affinity. Normally, PCS is cleared by the kidney but if it accumulates it can then lead to chronic kidney disease (CKD). We attempt to understand the nuances of interaction wherein bovine serum albumin (BSA) has been taken as a model protein. Absorption spectroscopy result indicated that in the presence of PCS (ranging from 2to 200 µM), the absorba

Abstract In this study, a novel process for synthesizing ZnO nanoparticles using a non-thermal plasma source generated by the Gliding Arc Discharge (GAD) system is presented. The physicochemical properties of the synthesized nanoparticles were characterized using diverse techniques such as scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), UV-Visible spectroscopy (UV-Vis), Fourier transforms infrared spectroscopy (FTIR), and X-ray diffraction (XRD). Furthermore, the effectiveness of the synthesized ZnO nanoparticles for wastewater treatment was evaluated by testing th

Abstract:

Background: The Natt-Herrick method is commonly used in veterinary laboratories for quantitative white blood cell counting in birds, as standard automated cell counting is unreliable due to the nucleation of all avian blood cells; as a result, quantitative white blood cell counting in birds is still done by hand. Aim: The research work was designed to compare the staining capacity and suitability of Hibiscus sabdariffa red calyx powder modified Natt-Herrick’s stain and as a natural staining substitute to commonly used standard avian dilution fluids, Natt-Herricks stain and brilliant cresyl blu

Objective: To characterize the egg from three hen genotypes: Mexican Creole (MC), Hy-Line Brown (HLB) and Rhode Island Red (RIR). Design/Methodology/Approach: Three groups of each genotype were formed using 75 hens (30 MC, 30 HLB and 15 RIR), 20 weeks old. Daily, for 84 days, two eggs were chosen randomly from each group to determine: weight (w, g), length (L, cm), width (Wth, cm), shape index (SI), volume (VOL, cm³), area (AR, cm²), shell color (SCo), yolk color (YCo), white weight (WW, g), yolk weight (YW, g), shell weight (SW, g), white proportion (WProp), yolk proportion (YProp), and shell

Abstract:

Recent evidence suggests that Alzheimer’s disease is a vascular disorder that can be accelerated by ischemic stroke. We propose that the underlying pathophysiology accelerating degenerative changes is due to blood brain barrier disruption following ischemia. A transient middle cerebral artery occlusion suture model was used in triple-transgenic AD mice and C57/Bl6 wild type controls. A separate triple-transgenic AD mice group was used for sham control. The middle cerebral artery was occluded for 1 hour followed by reperfusion. Mice were evaluated for sickness behavior and received a modified n
