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…

The Quantum-Mechanical Model of the Atom Introduction: The theory of quantum mechanics explains the behavior of the particles, such as photons (particles of light) and electrons, in the atomic and subatomic realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy…

1-What factors will help you decide if the existing internetwork is in good enough shape to support new enhancements? keeping a track of round trip response time, regular checkups of major routers, firewalls and switches, identifying sources and destinations of network traffic, analyzing its direction and balancing the data travel between source and destination are the some important factors. Documentation should be done for Data stores and traffic flows, the number of stations, average time a…

Paragraph 1 The research done by Haines on how the atomic structure of FePO4 varies when temperature increases from 294K to 1073 shows few crystal chemical relationships between SiO2 and FePO4. There is a first order variation of cell parameters and atomic orientations with temperatures lower than 980K and α-phase plays a dominant role over β-phase at high temperature. For the α-phase FePO4, the cell parameters increase with a non-linear trend when temperature increases linearly. The volume…

Acoustics is the branch of physics concerned with the study of sound. Sound is a wave made of vibrations in the air. Waves can be measured in a range of different ways: by their amplitude, wavelength, frequency, speed, and, at times, their phase. Sound information is transmitted by the amplitude and frequency of the vibrations, where the amplitude is experienced as loudness and frequency as pitch. The vibration is started by some mechanical movement and this causes a vibration on the molecules…

How was Avogadro’s number determined? What are the evidence of international co-operation and evidences used to support the value of Avogadro’s hypothesis (numer)? What is a hypothesis? It is a proposed explanation for a phenomenon, which can be described as ‘provisional'. However, a hypothesis cannot be identified as a prediction; it is a priority for it to allow people to make predictions of experiments that can be tested. If the results from this experiment are coherent with the prediction…

James Watson along with Francis Crick helped discover what we know about DNA today. They helped shape what we know about DNA and changed the world with scientific contributions. James Watson along with his colleagues helped shape the modern science of today with his many studies of DNA, cancer, and genomes. James Watson was born in Chicago, Illinois on April 6th, 1928. When he was young he attended Horace Mann Grammar School for 8 years and then attended South Shore High School for two years.…

dined at the Leaky Cauldron for lunch. I devoured the fish and chips fast enough to grab a frozen butter beer on the way to our next stop, the Mummy. This was a ride like no other. We flew backwards, forwards, to the left, to the right, in every diffraction. Along with the crazy direction changes, there were even more surprises such as the ceiling being engulfed in flames, on purpose of course. It was a great day at the park. On our way back to our beach house we stopped for vegan cupcakes. I…

the powders were protected from light by wrapping the vials with an aluminium foil. After one month storage, the powder samples were evaluated for drug content, in vitro aerosolization, surface morphology and solid state characterization by X-ray diffraction studies following the above mentioned procedures. Statistical analysis All the data was processed and their mean ± standard deviation values were determined using the Microsoft® Excel spreadsheets. Statistical analysis of the data (mean ±…

3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…
