Article
One of the most widely used methods for diagnosing diseases in human tissue is computed tomography (CT). Clinically, CT scans may require contrast media, such as Iohexol, to enhance images of different tissues and organs. However, these iodinized contrast agents have limitations, such as short blood duration, requirement of high-concentration injec...

Nucleic acid (NA) extraction is an essential step in molecular testing for a wide range of applications. Conventional extraction protocols usually suffer from time consuming removal of non-nucleic acid impurities. In this study, a new magnetic nanoparticle (MNP) is presented to simplify the NA extraction. A core-shell design, comprising of a ferrom...

Up to date most traditional fluorescent dyes that serve to detect nucleic acids in a selective manner face growing environmental and economic challenges due to their high toxicity, expensiveness, the long staining times required and the low sensitivities. Further attention went to replace the current widely used ethidium bromide (EB) by more safe a...

This study examined the preparation of MCM-41, Ni-MCM-41 and Co-MCM-41 from silica extracted from rice husk ash (RHA) via sol–gel technique. The materials were characterized by X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), Diffuse reflectance UV–Vis (DR/UV–Vis),Energy Dispersive X-...

Magnetic nanoparticles with specific surface features are interesting materials for biomedical applications. The combination of molecular interactions on small particles with macroscopic cohesion forces offers unique opportunities. This work reports the synthesis of magnetic core–shell nanoparticles with alkylimidazolium coated surface for effectiv...
Article
Three sugar‐based surfactants containing a double hydrophobic chain and two side‐by‐side arranged sugar head groups were synthesized by a click‐chemistry approach and investigated on assembly and surface active behavior. The surfactants exhibited higher packing parameters and lowered the surface tension more effectively than previously investigated...

The biochemical composition of normal human brain tissue in comparison with that of brain-tumour tissue was studied and diagnosed by means of the attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy technique. IR spectroscopy is a potential histopathological tool for detecting and diagnosing cancer and other diseases. In t...
Article
Background High efficiency in terms of reactions yield and purity has led to the extensive utilization of the copper catalyzed azide alkyne cycloaddition (CuAAC) in various fields of chemistry. Its compatibility with low molecular weight alcohols promotes the application in surfactant synthesis to tackle miscibility constraints of the reactants. O...

The development of promising magnetic nanocatalysts is one of the key research topics in the field of catalysis. This is because of their versatile surface physicochemical, magnetic, and size-dependent catalytic properties. Herein, an optimization strategy for the synthesis of high-value fuel grade chemicals from hydro-deoxygenation of biomass-deri...

The antibacterial activity of the extracted compounds of Capparis spinosa has been evaluated on some gram-positive and gram-negative bacteria. Two compounds have been isolated and purified by column chromatography (silica gel). The extracted compounds were identified by FT-IR, 1 H, 13 C NMR and Mass techniques. In this study, the results showed tha...

Background: Diagnosis of lung cancer is often delayed because most of the patients are asymptomatic during the primary cancer stages. Infrared spectroscopy is an improved technique compared with the others for identifying abnormal tissue types because of its spatial and spectral capabilities. Therefore, this study is taking an advanced advantage of...
Article
A base-induced cyclization reaction of 1,1-bispropargyls has been examined. Alkali treatment of 2,2-bispropynyl acetic acid derivatives in aqueous ethanol mostly provided 3-methylbenzoic acid. Investigations on substituent effects indicate the requirement of an electron-withdrawing group causing CH acidity and the center of the dipropargylic struct...
Article
A series of reverse Y-shaped surfactants containing aromatic and aliphatic linkers to combine two short hydrocarbon chains and one carbohydrate head group was prepared. Liquid crystalline behavior, air–water interfacial properties, and efficiency as an emulsifier was investigated for each reverse Y-shaped surfactant. All reverse Y-shaped surfactant...
Article
Novel series of tetra-cationic ionic liquids containing alkyl or phenyl side chains and ester groups within the same molecule were successfully prepared. Based on imidazoliumand benzimidazolium, these ionic liquids were synthesized from readily available starting materials in high yield. Surfactant properties including liquid crystalline behaviour...
Article
Silica extracted from rice husk ash was functionalized with 3-mercptopropyltrimethoxysilane (MPTMS) and then oxidized to sulfonic acid at room temperature and pressure. The FT-IR analysis shows bands at 1354-1166 cm(-1) due to the asymmetric and symmetric stretching of SO2 group. The C-13 CP MAS NMR of RHAPrSO(3)H showed chemical shifts at 58.6, 12...

Silica extracted from rice husk ash was functionalized with 3-mercptopropyltrimethoxysilane (MPTMS) and then oxidized to sulfonic acid at room temperature and pressure. The FT-IR analysis shows bands at 1354–1166 cm−1 due to the asymmetric and symmetric stretching of SO2 group. The 13C CP MAS NMR of RHAPrSO3H showed chemical shifts at 58.6, 12.1 an...
Thesis
Full-text available
Alkylation of phenol has been a subject of interest due to its industrial importance. In this book, the new mesoporous silica modified with sulfanilic and sulfonic acids was synthesized by using rice husk ash (RHA) as the silica source and used to study the liquid-phase alkylation of phenol with tert-butanol (TBA) as an alkylating agent. The 29Si M...

Sulfanilic acid was immobilized onto rice husk ash via 3-(chloropropyl)triethoxy-silane to form an acidic solid catalyst denoted as RHAPhSO3H. The BET surface area was found to be 308 m2 g−1. Pyridine adsorption study revealed the presence of Brønsted acid sites. The EDX analysis showed the presence of S (10.88%) and N (10.37%). The 29Si MAS NMR sh...
