through aggregation [9]. A STF-impregnated Kevlar with no impact on it has a high rate of comfort and flexibility. However, the STF behaves like a rigid solid and boost the ballistic protection of body armor. STF is saturated with colloidal silica nanoparticles. When the hydrodynamic forces overcome the inter particle forces at high shear rates, hydrodynamic clusters form and shear thickening happens [10]. Consequently, this reaction improves the energy absorption of Kevlar body armor as the…

GBM tumors biologically present a number of challenges for development of anticancer drugs and their delivery to the tumor site. Perhaps the biggest obstacle is the localization of tumors in the brain, which implies that the anti-cancer agent must be able to penetrate the blood brain barrier (BBB). The BBB is a highly selective permeability barrier that separates circulating blood from cerebrospinal fluid in the Central Nervous System (CNS). It is mainly formed by endothelial cells lining the…

Problem Statement Industries are generated waste water, which contain dyes and pigments in waste water. Characteristically high in colour and organic content (Grag, et al., 2004). Dyes are widely used in industries such as textile, rubber, paper, plastic, and cosmetic. There are many of dyes exist in industries and one of them is methyl red and through nano zerovalent iron removal of dyes from waste water. Dye industry effluents constitute one of the most problematic wastewaters to be treated…

When I was in Haiti, I remember sitting in class thinking about how much I love biology and chemistry. Coming back from school, I always told my parents and my little brothers what I learned in those classes. When I came to this country three years ago, my interest in the scientific field grew more. I finally thought deeply about what I wanted to do with my life and decided to major in chemistry. I became so interested that even when I was bored, I went through my chemistry book just to read and…

Cerium is a rare earth element of the lanthanide series (atomic no. = 57– 71) of the periodic table. Among the various rare earth metals, cerium granted a hugeattention towards scientific community due to its catalytic antioxidant property. Usually, antioxidants protect cells from oxidative damage, mediated by ‘reactive oxygen species’ (ROS), which include free radicals such as superoxide anion (O2•-), hydroxyl radical (•OH), singlet oxygen (1O2) and non-free radical species like hydrogen…

Gold Nanorods (GNRs) without damaging host cells? A: Current research is dedicated to conjugating nanoparticles to antibodies, enzymes, receptors and various proteins throughout the body. With their unique optical ability to absorb and scatter light, noble metals, such as gold, makes a perfect contrast candidate to photo-actively increase the temperature of nanoparticles. Conjugating the nanoparticles to an enzyme structure, you assure anti-Hexokinase II antibodies will directly attach to…

In this work we have prepared ceramic-polybenzoxazine composites based on poly(P-ddm) as matrix reinforced by 0, 3, 5, 7, 10, 15, and 20 wt.% of GX-540 silane-treated nano-Cr2O3 filler via a solution blending method in THF. These nanocomposites are used as new organic coating materials. The effect Cr2O3 nanofillers inclusion on the viscoelastic properties of poly(P-ddm) is studied using dynamic mechanical analysis (DMA). Figure 76 illustrates the change in the storage modulus at 50oC and…

Abstract In this paper CuO-NH-NH2 nanoparticle was synthesized and used to remove anionic dyes from single and binary systems. The scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDAX) and X-ray diffraction (XRD) were used to characterize the nanoparticle. Direct Red 80 (DR80) and Direct Green 6 (DG6) were used as anionic dyes. The effect of adsorbent dosage, dye concentration and pH on dye removal was evaluated. Kinetic…

limitations of conventional drug delivery systems through the fabrication of nanostructures capable of encapsulating and delivering small molecules. Nanoparticles have small sizes ranging from 1-200 nm which can improve the bioavailability of therapeutic agents and pass through biological barriers of the eye[8]. Another important characteristic of nanoparticles is that they can be fabricated bespoke through chemical processes. For examples, particulate nanocarrier-based delivery systems have…
