If m=0,nano tube are called as the ZIGZAG NANOTUBES. And if n=m nano tubes are called as the ARMCHAIR NANOTUBES .else they are called as CHIRAL. SWNTs are an very important variety of carbon nanotube because as the most of their properties change significantly with the
The malleability and ductility depends upon the upon the ease with which the layers of atoms can slide and the crystal structure of metals. For example Gold has the highest malleability , whereas it is difficult to bend potassium or sodium into sheets. What is the need of an Alloy? Alloy is a homogeneous mixture of a metal and a metal or a metal and a non metal. By introducing few atoms of another substance in the crystal lattice of the metal we can change the properties of them .
Technology has been so important in our lives that we must have it everywhere and anytime because many different technologies were invented to make our lives easier and more comfortable, without which we would feel alienated from the rest of the world. It is undeniable that people have been very reliant on technology in every aspect of life but how has this affected creativity and communication among us? Technology has improved our communication in many ways as it has broken barriers of distance between humans around the world. For instance, mobile phones and social networking sites have made us closer to each other as we can instantly contact one another. Back in the old days, humans use different ways to contact each other, such as writing letters.
It deals with matter on scale ranging from sub-atomic particles to starts in the entire universe. It is also very difficult to understand but it is considered to be the most fundamental science so without it we wouldn’t have biology, chemistry or anything
It is known to be a semiconductor. Doping of Polyaniline: Polyaniline in the undoped state is a poor semiconductor with a conductivity of about 10-8 ohm-1/cm. Once it is doped with p-hydroxybenzene sulphonic acid (PHBSA), its conductivity increases by a factor 10 ohm-1/cm or more depending on the dopant and forms of polaron/bipolaron structure that will increase conductivity due to the increased delocalisation. Among the various oxidation states that polyaniline can exist in, the one that can be doped to a highly conductive state is the moderately oxidized emeraldine base. This form of Polyaniline has a structure which consists of equal proportions of amines (–NH–) and imine (=N–) sites.
INTRODUCTION With the rapid progress of technology and science, nanotechnology becomes a prominent accomplishment of the humanity. The ability to observe and comprehend the nanomaterial has a beneficial human to extend our knowledge in a variety range of industries and scientific endeavors. Nanotechnology is defined as a structure that conducted the size of one nanometer to one hundred nanometers and it is invisible to the human eye. Nanotechnology allows the scientists to manipulate one particular particles property at a very small size and adapt it in any applications in real life (Understanding Nano, 2016). One of the applications that makes nanotechnology exceedingly successful is the use of nanomaterial in sunscreen Sunscreen provides
Longboards are beginning to gain much popularity among different age groups all over the world. It is not restricted to a particular culture but is accepted by all kinds of people of all races. Although, not all destinations are good for longboarding hence, this cannot be done in just any place. There are some specific areas that are outrightly good and ideal for longboarding. Aside from longboarding been highly rated and an intriguing sport, there are many reasons longboarding is awesome.
Sports being part of everyone’s life has been playing an influential part in every aspect of our society. Sports earlier was limited only to the leisure activity or to the physical activities carried on by the individuals to pass their time and keep themselves fit. But in today’s time sports is not limited only for entertainment and health purposes but has been extended for commercial activities, thereby being considered as a big source of earning income by grabbing business opportunities in the area of sports. Various sports teams are organized and on their formation some special recognition is required. Thus, they are recognized or differentiated from other teams by giving specific names to them.
are affected. These changes include an increase in electrical conductivity, electrical resistivity or magnetic coercivity of nanoparticle .Nanosized materials can be organic ,inorganic or combinations that are of nanometer size .The particles can be amorphous ,semi crystalline or crystalline .There is growing interest in nanostructures from molecular building blocks because of the flexibility and versatility inherent in their assembly .Owing to the relatively weaker interactions between the building units ,the trademark of molecular materials, it is likely that some of the fundamental characteristics of molecular nano materials are different from those of metals and semiconductor nanostructures. Considerations such as these suggest that molecular nanostructures are highly gifted from the perspectives of novel physical phenomena as well as technological applications [Horn and Reiger.,2001]. The unusual property of nanoparticles is due to following
Nanotechnology This is a technology where used in natural an artificial structures. It is mainly designing, producing and characterizing devices in nanometer scale. Nano meter scale is said to be 10000 times thinner than human hair. But this scale is different in different research papers due to the sizes of hair can be vary. Beside that, it is able to get an idea of how much nano particles small are.
