Lung cancer, breast cancer and colorectal cancer are the most prevalent fatal types of cancers globally. Gallic acid (3,4,5-trihydroxybenzoic acid) is a bioactive compound found in plants and foods, such as white tea, witch hazel and it has been reported to possess anticancer, antioxidant and anti-inflammatory properties. In this study we have redesigned our previously reported anticancer nanoc...

We report a novel method to pattern the stiffness of an elastomeric nanocomposite by selectively impeding the cross-linking reactions at desired locations while curing. This is accomplished by using a magnetic field to enforce a desired concentration distribution of colloidal magnetite nanoparticles (MNPs) in the liquid precursor of polydimethysiloxane (PDMS) elastomer. MNPs impede the cross-li...

Magnetism is an intriguing physical cue that can alter the behaviors of a broad range of cells. Nanocomposite scaffolds that exhibit magnetic properties are thus considered useful 3D matrix for culture of cells and their fate control in repair and regeneration processes. Here we produced magnetic nanocomposite scaffolds made of magnetite nanoparticles (MNPs) and polycaprolactone (PCL), and the ...

We employ positron annihilation lifetime spectroscopy (PALS) to measure the temperature dependent fluctuations in a local free volume of water confined in a variety of mesoporous materials with different pore sizes and morphologies. We demonstrate that this unconventional approach can be used to probe the dynamics and glass transition temperature, Tg, of water in confinement. In the simplest ca...

A UV, visible and NIR range irradiation responsive magnetite/graphite nanoplatelets composite was successfully synthesised via a single-step facile in-situ electrochemical exfoliation method using natural vein graphite. The spectral analysis revealed that as-synthesised photocatalytic could rapidly degrade the organic dyes with 96.1, 78.0 82.6 % efficiency in 120 minutes under respective Visibl...

In this study, different variables that influence cesium adsorption from aqueous solutions were investigated by a synthesized nanocomposite. The spherical mesoporous silica surfaces modified with potassium hexacyanoferrate and characterized various methods such as FT-IR, XRD, FESEM, TGA BET/BJH. response surface methodology based on Central Composite Design was applied to optimize the ion condi...

Assessment of adsorption zinc (II) ions from aqueous solution using alginate-SBA-15 sorbent nanocomposite was investigated as a function of zinc concentration, solution pH, and contact time. For that purpose, the alginate-SBA-15 nanocomposite adsorbent was prepared through encapsulation method by immobilization mesoporous SBA-15 into a polymeric matrix. Identification of functional groups and s...
