an elongated particle (as in a sickle cell, myosin, or fibrin) that appears as a spindle-shaped body under a polarizing microscope
Micro structure of concrete with nano materials gets changed like anything and is resulting tremendous increase in compressive strength apart from increase in specific surface area.
Nano Technology
as the name implies its the study of a structure in nanometes every molecule and atom has structure when referring to nano it means analysing the structure on a nano scale like we see water as fluid but on a nanoscale u see 2 elements 2 hydrogen and 1 oxygen molecule nano structure is basically studying molecules on the nano scale :)
A "smart material" is one having a molecular structure that responds in a particular and controlled way to influences upon it. These range from magnetically-changed materials, to "memory" molecules that return to their original form, to materials that generate an electric charge when pressed, twisted, or warped. These materials can significantly change their mechanical properties (such as shape, stiffness, and viscosity), or their thermal, optical, or electromagnetic properties, in a predictable or controllable manner. Some types of smart materials are piezoelectrics, electrostrictors, magnetostrictors, and shape-memory alloys.
que es nanocombustion
I wish I knew too.
Normally a composite material that includes nano scale ferritic compounds within the matrix material
microfill composites are composites that contain very small glass fillers approx 0.04 micrometers that are very smooth and have excellent wear resistance. Nano fill composites have glass fillers that are even smaller in size which change the property of the composite.
Nano = Very small.
Yes, that is what its called. With "nano 4" i assume you mean the 4th generation of ipod nano.
Small.
Composite means the mixture of the two substance in the definite proportion. Now a time the use of the nano-composite is at its peak as which defines that the mixture of the two substance but one of the substance should be in the nano dimension i.e. from 1-100 nm in size. So combining the two substance is not just a random process . it is done in order to increase the properties of the substance through a process called reinforcement.
Yes. 1) Nano-engineered materials are stronger and better than normal materials. 2) Nano-engineered liquids can be useful in fields of medicine and machinery. 3) Nanobots can go into people's bodies to kill virusses/cancer.
the nano structur material are good absorber as compared to bulk and microsized material
I think it is to make everyday items for practical/adaptable to our environment and more convenient for us??
"Bullet proof glass" is not a single thing, but a class of building materials that are composite in nature (several layers of differing thickness and materials). Generally, the layers of ballistic glass include glass laminate, polycarbonate, or acrylics bonded with polyvinyl butyral, polyurethane or ethylene-vinyl acetate.
it means 1 billionth of a unit!!
