In this paper, we report a layer-by-layer approach for the preparation of a concentric recyclable composite (CoxNi1-xFe2O4/SiO2/TiO2; x = 0.9) designed for wastewater treatment. The prepared composite was investigated by X-ray diffraction spectroscopy, high-resolution transmission electron microscopy and scanning electron microscopy (SEM) supported with energy dispersive X-ray (EDX) spectroscopy to analyze crystallinity, average particle size, morphology and elemental composition, respectively. The antimicrobial activities of the prepared composite have been investigated against multi-drug

Density functional theory calculations using B3LYP/3-21G level of theory have been implemented on 6 carbon nanotubes (CNTs) structures (3 zigzag and 3 armchair CNTs) to study the energetics of the reverse osmosis during water desalination process. Calculations of the band gap, interaction energy, highest occupied molecular orbital, lowest unoccupied molecular orbital, electronegativity, hardness, and pressure of the system are discussed. The calculations showed that the water molecule that exists inside the CNT is about 2-3 Å away from its wall. The calculations have proven that the zigzag

Nanomaterials have received considerable attention due to their unique properties; they have high surface area compared to volume ratio, giving them superior chemical, optical and thermal characteristics. Nanomaterials have also both diagnostic and therapeutic applications. In this mini review, we are highlighting valuable data about human immunodeficiency virus (HIV), its relationship with cancer and its potential treatment with some nanomaterials such as silver nanoparticles (Ag NPs). © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

In the present work, a single crystal of alanine and hippuric acid was prepared through the slow growth dynamics of sample evaporation. The crystallinity, structure, and cell parameters of the produced single crystals were determined by X-ray diffraction (XRD) analysis. While, frequency shifting and the various functional groups of alanine with hippuric acid were investigated by FTIR and FT-Raman studies. In addition, grain size and the morphological shape of alanine hippurate (AH) single crystals were examined by FE-SEM analysis. Transmission of light through the grown material was defined by

Abstract: Neurodegenerative disorders especially Alzheimer’s disease (AD) are significantly threatening the public health. Acetylcholinesterase (AChE) inhibitors are compounds of great interest which can be used as effective agents for the symptomatic treatment of AD. Although plants are considered the largest source for these types of inhibitors, the microbial production of AChE inhibitors represents an efficient, easily manipulated, eco-friendly, cost-effective, and alternative approach. This review highlights the recent advances on the microbial production of AChE inhibitors and summarizes

The potential use of chitosan films as a replacement to synthetic polymers in food packaging applications is receiving remarkable attention due to their biodegradability and antimicrobial properties. This study presents the preparation of composite films from chitosan as polymeric matrices, and rice straw and nano rice straw fibres as reinforcements. The films were produced via wet mixing and casting techniques with various reinforcement contents (25–35 wt%). The aim of this research is to investigate the physical, mechanical, chemical, and thermal properties of the synthesized composite films

In this editorial trend, we aim to collect and present recently available data about the characteristics of SARS-CoV-2 virus, severity, infection, replication, diagnosis, and current medications. In addition, we propose the role of nanomaterials in controlling and treating COVID-19 through their antiviral and antibacterial potential with suggested action mechanisms indicating the capability of interaction between these nanomaterials and SARS-CoV-2. These nanomaterials might be among the possible and most effective cures against coronavirus. © 2020, Springer-Verlag GmbH Germany, part of

Potato plants can be infected by different bacterial diseases, among them, the potato brown rot disease, caused by Ralstonia solanacearum. The novelty of the present research is to assess the potential impact of the synthesized copper oxide NPs (CuO NPs)-streptomycin nano-drug synthesized by gamma irradiation for inducing the systemic resistance against potato brown rot disease. CuO NPs-streptomycin was completely-characterized by UV–Vis., XRD, FTIR, HRTEM, SEM, and EDX elemental analysis. In the greenhouse experiment, the efficiency of CuO NPs was tested after three times of application

This work reports the detailed structural characterization of Zn2+ ion-substituted cobalt ferrite nanoparticles (CFO NPs; Co1−xZnxFe2O4; x = 0.00, 0.25, 0.50, and 0.75), prepared using a facile sol–gel method. It correlates structural changes with magnetic and dielectric properties. The as-synthesized samples were investigated by X-ray diffraction (XRD) analysis, BET surface area analyzer, energy-dispersive X-ray (EDX), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), Mössbauer spectroscopy, and impedance analyzer. The pristine sample

The current study highlights a sustainable fabrication of nanoscopic thermite (MnO2/Al) system, composed of MnO2 nanoparticles with an average particle size of about 20.8 nm prepared by a hydrothermal processing technique. In addition, it contains aluminium particles having a combustion heat of 32,000 J/g, which is very attractive for advanced energetic systems. Plate-like aluminium nanoparticles with an average particle size of 100 nm were developed by wet milling. Our results revealed aluminium optimum solid loading in tri-nitrotoulene (TNT), which was found to be 8.0 wt%. At this optimum
