Improved photocatalytic degradation of methylene blue and rhodamine G dye under UV-radiation by rGO-MoO3
Ruhinaz Ushal, Bilal Ahmed, Arvind Singh, Animesh Kumar Ojha
Physica Scripta, 2025
In this work, we report facile synthesis of rGO-MoO3 nanocomposites as photocatalysts via one-step hydrothermal method. Initially, the synthesized materials were characterized by different physicochemical methods to reveal the structural, morphological, optical, and other properties. The transmission electron microscopy (TEM) and Raman spectroscopy results validate the formation of rGO-MoO3 nanocomposites. The optical bandgap values of pristine MoO3 (3.47 eV) and rGO-MoO3 (3.36 eV), reveal that they can serve as ultra-violet light photocatalysts, for the decomposition of organic pollutants e.g. methylene blue (MB) and rhodamine G (RhG) dye. The rGO-MoO3 nanocomposites significantly enhanced the photodegradation efficiency as compared to MoO3, due to the interfacial interaction between the composite parts and promoted the transfer of charge carriers from MoO3 to rGO, causing a reduced rate of electron-hole recombination. The highest degradation efficiency was observed for rGO-MoO3 nanocomposite {for MB (∼50%) and RhG (∼96%)}, whereas for MoO3 {for MB (∼40%) and RhG (∼43%)}. This report highlights a noteworthy impact of rGO with MoO3 nanocomposites as a photocatalyst.
Cu-Fe and Cu-Ni metal blend-infused polystyrene-based electrospun nanofibers for dye degradation
Varun Kumar Sharma, Prem Kumar, Sunil Kumar, Mohd Yusuf, Bilal Ahmed
Discover Chemical Engineering, 2024
The mitigation of hazardous effects of chemical dyes on the environment and living organisms, greatly demands an efficient and effective management of dye-laden wastewater. One such solution gaining prominence is the utilization of metal-infused nanofibers-based dye removal techniques, which are simple, effective, and environmentally friendly. In this report, we present the fabrication of mechanically stable hydrophobic nanofibers infused with metal blends, fabricated through the utilization of electrospinning techniques. The successful fabrication of these mechanically stable hydrophobic nanofibers is evidenced through contact angle measurements, tensile tests, and FESEM analysis. While polystyrene-based nanofibrous mats were anticipated to be effective, nanofibrous mats infused with Cu-Fe and Cu-Ni metal blends exhibit exceptional efficacy in degrading dyes. The size and morphology of nanofibers depend on polymer concentration, with the average diameter increasing from 13 to 20%. At a 20% polystyrene concentration, only nanometer-scale fibers of polystyrene polymers were fabricated, while both Cu-Fe and Cu-Ni metal blend-infused fibers were synthesized in micrometers. Fibers infused with Cu-Fe and Cu-Ni metal blend at a 17% polymer concentration displayed nano-scale diameters, confirmed by FESEM characterizations. The heat-based technique is identified as an accessible and cost-effective approach for industries reliant on color-based processes.

Detection of Escherichia Coli Bacteria Using Few-Layer Black Phosphorous-Based Surface Plasmon Resonance Sensor
Prem Kumar, Rajeev Kumar, Bilal Ahmed
International Conference on Integrated Circuits Communication and Computing Systems Icic3s 2024 Proceedings, 2024
In this paper, 2D material-based black phosphorus (BP) and copper (Cu) layer structure of the SPR sensor-based detection of Escherichia coli (E.C.) bacteria with increased performance parameters has been proposed. The simulation results have been determined theoretically using MATLAB and Comsol software with finite element method (FEM). N-FK51A prism is coated with a Cu layer to generate the plasmonics, followed by multiple BP layers (6*BP), which works to increase the field intensity, sensitivity and figure-of-merit (FoM) of the sensor. The higher sensitivity, and FoM of 268.4°/RIU, and 365/RIU are achieved with an increase in the 6*BP layer at 633nm wavelength. As a results, the suggested sensor is increased the sensitivity between the refractive index of 1.33–1.39RIU.

Handbook of Nanofibers and Nanocomposites Characteristics Synthesis and Applications in Textiles, 2023
This chapter aims to give a concise overview of recent research considering the synthesis, properties, and applications of polymer/metal-oxide composites of nanostructures. There are different techniques for the synthesis of polymer, metal oxide, and polymer/metal-oxide nanocomposites with efficient surface morphological structure, and novel properties. The chapter describes the overview of the synthetic techniques, characteristics/properties, and applications of polymer/metal oxide from a material science perspective. Various physical and chemical synthesis approaches such as physical vapor deposition, thermal evaporation, pulsed laser deposition, spray pyrolysis, chemical vapor deposition, sol-gel, hydrothermal, co-precipitation, etc. are employed for the production of polymer/metal-oxide nanocomposites. The synthesis of metal-oxide nanostructures into the polymer matrixes can be done using two different processes, that is, ex situ and in situ processes. The incorporation of nanoparticles into the polymer matrix improves the physical, mechanical, and rheological properties. Researchers have long been interested in polymer/metal-oxide nanocomposites because of their electrical and optical properties.
Modern perspectives of curcumin and its derivatives as promising bioactive and pharmaceutical agents
Mohammad Yusuf, Sadiya, Bilal Ahmed, M. Gulfishan
Biointerface Research in Applied Chemistry, 2022
In the current era of eco-preservation, global research has focused on using raw and sustainable natural products with new clean technologies. New pharmaceutical or pharmaceutical agents from renewable sources are considered as essential as pure chemicals or certified fragments. A variety of natural phytoconstituents have been shown to reduce the risk of certain diseases and disorders, for example, diabetes, heart disease, cancer, neoplastic, and other health disorders. And, therefore, ongoing efforts to identify specific chemicals in these foods may contribute to their positive effects on beans/grains, fruits, vegetables, etc. Many of the phytochemicals that occurred as natural products in medicinal plants offer many opportunities in natural product research due to their versatile uses and various formulation. Curcuminoids are polyphenols found in the under-soil rhizome of Curcuma longa L. and have been used for centuries for spice, culinary, and food coloring purposes, and description also documented in the alternative system of medicines such as Indian Ayurveda, Sidha, Unani, and Chinese medicine system. It has been observed from the literature that the C. longa rhizome or commonly known as turmeric has several phytochemicals to possess anti-inflammatory, hepatoprotective, neuroprotective, antioxidant, anticancer, cardioprotective properties, and many more. The review highlights the recent progress of curcumin and its derivatives as promising bioactive and pharmaceutical agents with emphasis on future research dimensions required to propose curcuminoids as promising candidates for therapeutic and pharmacology-related sectors.
