Top-down and Bottom-up approaches to nanotechnology An overview in the context of developing Proton-fountain Electric-field-assisted Nanolithography (PEN): Fabrication of polymer nanostructures that respond to chemical and electrical stimuli. Many of them are also animated. But could potentially be overwhelmed as the size and complexity of the desired assembly increases. presentations for free. PowerPoint is the world's most popular presentation software which can let you create professional Introduction to Nanotechnology powerpoint presentation easily and in no time. 1. Download Nanotechnology PowerPoint templates (ppt) and Google Slides themes to create awesome presentations. NANOTECHNOLOGY 2. Most useful structures require complex and thermodynamically unlikely arrangements of atoms. Bottom-up approach: In bottom-up approach is also known as “molecular manufacturing” and “molecular nanotechnology”, in this the materials go through the machines from components of the molecule via a process of self-gathering. Keywords: Nanoengineering, Nanotechnology, Freshman, Bottom-up, Nanomanufacturing, Ethics, Sustainability. 10. Molecular components arrange themselves into some useful conformation using the concept of molecular self-assembly. View Notes - nanotech_bottomup.ppt from CHEM 41025 at Vishwakarma Institute of Technology. Presently, nanotechnology is very expensive and developing it can cost you a lot of money. Using the bottom-up approach, you would use nanotechnology to assemble the chip atom by atom, placing each type of atom in a specific location to build the circuit. A nanometer is a billionth of a meter. Nanotechnology is defined as fabrication of devices with atomic or molecular scale precision. Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over 1000 impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. Lecture 4. Bottom-up planning tends to leave decisions about what, when, how, and with whom to buy and sell far more in the hands of market participants than in the case of central planning. Lithography is an example in which the growth of thin film is … INTRODUCTION TO NANOTECHNOLOGY. Clipping is a handy way to collect important slides you want to go back to later. Synthesis of nanomaterials: top-down and bottom-up approaches There are two main approaches to synthesize nanomaterial or nanoparticle. They are all artistically enhanced with visually stunning color, shadow and lighting effects. The two basic approaches to creating nanomaterials in a controlled and repeatable manner are the “top-down” and “bottom-up” techniques as shown in Figure 3, either for atoms to assemble together (break) or disassemble (dissociate) bulk solids into small pieces or to get on a few atoms from them. An opposite approach is to synthesize the material from atomic or molecular species via chemical reactions, allowing for the precursor particles to grow in size (bottom-up). - ...

There are two main type of approaches used in Nanotechnology: Bottom up approach – They uses forces that is operating at nanoscale to assemble small units to larger structures. The biological approach to nanotechnology has produced self-assembled objects, arrays and devices; likewise, it has achieved the recognition of inorganic systems and the control of their growth. Split of Energy Levels. 28 APPROACHES.. Two approaches can be taken when making something at the nano scale ; Top-Down approach ; Bottom-Up approach ; 29 TOP DOWN APPROACH. What does Nano or Nanotechnology mean? The top-down approach is a process of miniaturizing or breaking down bulk materials (macro-crystalline) structures while retaining the original integrity. - An Introduction to Nanotechnology Dr S. H.
