TASK 4 CORRELATING STRUCTURE ACTIVITY RELATIONSHIPS Task 4 aims to develop knowledge of the relationship between the structure of ENMs and their toxicity. In this study, different kinds of metal oxide nanoparticles, carbon nanotubes, and graphenes will be tested their toxicities and then their structures and their toxicities will be found their correlations. For MONMs, different coatings of ZnO will be tested toxicities and observed the relationships, while differences in their sizes and…

In this study, multiwalled carbon nanotubes@poly(p-phenylenediamine)-prussian blue (MWCNTs@PpPD-PB) nanocomposites were synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic…

I was born in Mexico and moved to the United States when I was three years old. Growing up my parents worked all the time and my older siblings would take care of my twin sister and I. Despite my parents not being able to be there at all times, they instilled in me the importance of school and hard work. It is because of their sacrifices and hard work that I have been able to become the person I am today. As a result of the various science related classes that I have taken, I intend to study…

calculate the activation energies Ea which were found to be 0.098 and 0.12 for Co and Cu oxides, respectively. These values are comparable to those published in other literature [47]. Although the temperature dependence of the temperature of NiO nanoparticles exhibits typical semiconductor feature like the other oxides under study, the -T data don't fit well with Eq.9 where the accurate analyses confirm that the data are better represented by the following…

When external antigen causes disease by infection, cell-mediated immune response in our body acts as basal defense system against exogenous pathogen. Native and adoptive immune system has established to attack infected cell by recognizing major histocompatibility complex (MHC). There are two major lymphocytes related to killing effect called cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells.[1], CTLs and NK cells recognize peptide epitope present on MHC class I to find infected cell.…

ischemia-reperfusion injury, performing Western Blotting to measure protein expression level, providing evidence for the potential clinical application of Diosgenin. In my last year in undergraduate, I joined Dr. Haiyan Chen's lab, we synthesized upconversion nanoparticles and nano-conjugates, applied them on bioimaging and tumor inhibition in both cancer cells and mice…

Nano-dots in Mammalian Gametes Imagining1 The Nano-dots, or Quantum Dots (QD), are nano-scale semiconductor devices with diameter up to 10nm, which were first discovered in 1980s2. Once stimulated, they give emission of light with specific colours, which is then visualised1-3. These nano particles have high size-tunability, once illuminated, different emission wavelength can be obtained by manipulating the size of dots3. Inorganic QDs are made up of two components, an atom-cluster core with…

Scientists make important contributions to technology and medicine through their discoveries. Nikola Tesla is distinguished for his futuristic inventions which serve as components of electrical systems in modern times. Another scientist who influenced contemporary technology is Joseph Henry, who developed the telegraph. Likewise, the acclaimed scientist Hans Christian Ørsted discovered electromagnetism, which broadened the range of scientific possibilities. Despite the eminence of Tesla, Henry,…

Chapter 1 Introduction Waste generated from food industries is a source of an untapped energy which is mostly dumped inland fills whereby it releases greenhouse gases into the atmosphere. It is very difficult to treat and recycle food waste due to its composition. Food industry produces large volumes of wastes, both solids and liquid, resulting from the production, preparation and consumption of food. These wastes lead to increasing waste disposal and can pose severe pollution problems and…

Bernardi et al., (46) assessed nanoparticle calcium carbonate (NPCC) by means of transmission electron microscopy and the effects of NPCC addition to MTA in regard to the setting time, dimensional change, compressive strength, solubility and pH. , The experimental groups were G1 (MTA), G2 (MTA with 5% NPCC) and G3 (MTA with 10% NPCC). The tests followed ISO and ADA standards. The dimensional change and compressive strength tests were measured immediately after setting, after 24 h and after 30…
