Spur gears are simple, easily manufactured gears and are usually the first choice when exploring gear options. Transmitting power between parallel axes, the teeth project radially on the disc. The sole variance in their identity remains the rack, which is covered more in-depth in Engineering360's Rack and Pinion Specification Guide.

Upcoming Events

    Chicago, IL

    The International Conference on Graphene and Semiconductors is to be held at Chicago, Illinois, USA during July 17-18, 2017 Organized by Conference series LLC.

    It will bring together world-class professors, researchers, scientists and students across the world to discuss about the current developments that are taking place in the field of Graphene. Graphene and semiconductor is designed in such a way to provide diverse and current research that will provide an in-depth analysis in that field. The International Conference on Graphene and semiconductor is organized with a theme of “The Rising Era of Graphene” with an objective to encourage young minds to overcome the challenges in the research field of Graphene materials by providing an opportunity to meet the experts.

    Graphene is an allotrope of carbon.It is made of a single layer of carbon atoms that are bonded together in a repeating pattern of hexagons.It is a is a thin layer of pure carbon it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. Semiconductors are crystalline or amorphous solids with distinct electrical characteristics.They are of high resistance and higher than typical resistance materials, but still of much lower resistance than insulators.

    Importance :

    Graphene is the thinnest strongest material in nature. This element is important because it may function as conductors, semiconductors, as well as insulators.Fullerene, graphene, and graphite are a few of the most important allotropes of carbonthat exist in nano scale dimensions, and all three have unique physical, material, and chemicalproperties. Fullerene, graphene, and graphite are all highly stable molecules due to the highactivation barrier caused by the structural arrangement. The three types of carbon can be achieved by restricting different dimensions. It can be rolled to form one dimensional nano tube,wrapped to form a zero dimensional fullerene, and it can be stacked in multiple layers to form three-dimensional graphite.The extraordinary chemical and thermal properties of Graphene are due to several factors. It is a chemically inert molecule. In the delocalized orbitals, electrons are free to move and therefore suffer very little energy dissipation, and there is no energy gap. The physical properties of Graphene is very significant because of its better conductivity and stability.
    Semiconductor devices can be mainly used to display a range of useful properties such as passing current more easily in one direction than the other, showing variable resistance, and sensitivity to light or heat.The electrons in semiconductors can have energies only within certain bands between the energy of the ground state, corresponding to electrons tightly bound to the atomic nuclei of the material, and the free electron energy, which is the energy required for an electron to escape entirely from the material.The problem that prevented graphene from initially being available for developmental research in commercial uses was that the creation of high quality graphene was a very expensive and complex process that involved the use of toxic chemicals to grow graphene as a monolayer by exposing Platinum, Nickel or Titanium Carbide to ethylene or benzene at high temperatures.The event has the objective of creating an international forum for academics, researchers and scientists from worldwide to discuss worldwide results and proposals regarding the soundest issues related to Graphene and Semiconductors. It will include the participation of renowned keynote speakers, oral presentations, posters sessions, Exhibitors, Sponsors and technical workshops.
