  • Carbon Nanotube Lab Report

    Introduction Before the invention of the electronic gas sensor in the 1920s, people relied on primitive and dangerous methods. These include canaries to detect low oxygen environments in mines, and flame lights to detect methane and oxygen levels. The replacement of these methods with electronic sensors has increased both the safety and reliability of gas detection. In addition, a wider variety of gases can be sensed and quantified. Despite these improvements, issues with sensors persist. Selectivity, the ability to differentiate between gases, proves a challenge, as do sensitivity to small gas concentration, repeat measurement stability, and cost. One possible way to compete with these challenges may be the carbon nanotube (CNT) transistor.…

  • Carbon Nanotube Research Paper

    The Nanotube Introduction: Nanotubes, specifically the carbon nanotubes are just one of the handful of structures engineers and scientist use today that fall in the nanoscale category. Structures in the nanoscale category are usually between 1-100 nanometers, which one nanometer is one-billionth the size of a meter. A confusing yet beneficial property found in materials at the nanoscale is a concept call quantum called quantum mechanics. In quantum mechanics the laws of classic or Newtonian…

  • Case Study Of Carbon Nanotubes

    CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…

    and how they breathe all the way up into space. A method they use for breathing in space is electrolysis. Other factors are the diet, the removal of waste, and the impact of space. In spacecraft fuel the two main categories are liquid and solid rockets, which have different combinations and impulse values. In the development of a spacecraft carbon nanotubes are expected to used. Rocket propulsion, of course, includes combustion. Combustion is where a substance reacts with oxygen and gives off…

  • Conductive Behaviour Of Graphene/Carbon Nanotube Hybrid Technique

    Part One: Conductive behaviour of graphene/carbon nanotube and graphene oxide/ carbon nanotube hybrid materials Experimental Introduction Although many CNTs and graphene based electrodes have been developed with outstanding properties, drawbacks are still noticeable using some methods. For instance, EPD method commonly produces unsatisfied CNTs film strength and on the other hand, CVD technique is costly. Moreover, graphene based electrodes needs lots of labour works which is time consuming…

  • Characteristics Of Carbon Nanotubes

    3.2 Carbon Nanotubes (CNTs) Carbon nanotubes have remarkable adsorption behavior in purification and detoxification of the environmental pollutants[12]. Their characteristics of being highly porous, having large specific area and being not solvable in aqueous solution because of the high Van der Waals interaction forces on the tube walls(pi-stacking) allow them to be great environmental pollutants adsorbent in solution. Thus, researchers have been concentrated on aqueous solution purification…

  • Synthesis Of Pb Film

    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…

  • Summary Of Mark Miodownik's Stuff Matters

    significance and characteristics of various forms of carbon in a historical lens. Although derived from the same element, graphite, diamond, and graphene all have unique properties unlike any other materials. Miodownik begins by offering a relatable anecdote to his childhood art class in order to truly show the readers the prevalence and wonder of carbon. He then focuses the central idea of the chapter on the effect of structure on properties and uses. Miodownik provides a thorough…
