Larix is a self-functioning, independent organization wholly focused on arranging conferences in multi-disciplines of research on various science fields. The conferences are administered by global influential scientists and scientific excellence. We are even open for the upcoming scientists and scholars, who are in need of a platform to give their voice a much needed larger volume.

International Conference on Recent Advances in Nanoscience and Nanotechnology (Nanotech 2019) is going to be organized in the beautiful city of Kuala Lumpur, Malaysia on June 20-21, 2019, primarily focusing on the theme “Nanotechnology for Better Health care”.

THE NANOTECH

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.

ALL ABOUT IT

After more than 20 years of basic nanoscience research and more than fifteen years of focused R&D under the NNI, applications of nanotechnology are delivering in both expected and unexpected ways on nanotechnology’s promise to benefit society.

Nanotechnology is helping to considerably improve, even revolutionize, many technologies and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.

What is the reason why carbon nanotubes conduct electricity?

Carbon nanotube have recently emerged as an important nanomaterial with enhanced properties such as high electrical & thermal conductivity, aspect ratio, and toughness. To get electrons to flow through a semiconducting carbon nanotube.Carbon nanotubes conduct electricity better than metals. When electrons travel through metal there is some resistance to their movement. This resistance happens when electrons bump into metal atoms.They are considered the ideal candidate for electronic devices, biosensor hydrogen storage cells, electrostatic discharge, and electrical shielding applications.

How can distinguish that a nanoparticle is alloy or core-shell?

A core shell nanoparticle is composed by two phases, one in the core and another one covering it. The alloy ones are composed by only one.

The phases have different spectra for different wavelengths of electromagnetic radiation and electron beans. That means that the different phases are going to absorb different amounts of electrons at a given wavelength, controlled by the acceleration imposed to it by an electrical tension. This is what happens in electron microscopy.

In order to identify the two phases that behave differently with electrons, one possibility would be using transmission electron microscopy (TEM). TEM places the electron emitter and the detector on opposite sides of the sample. That means that the electrons must propagate through the sample, thus being absorbed in different intensities for different phases. That you result in a core shell structure showcased as a core covered with a material with a different visual aspect. The alloy one will have just one aspect. An example is the microscopy below, where the one on the left (a) is an alloy structure and the one on the right (b) in a core shell structure.

Is cancer treatment possible through nanotechnology? How?

Nanotechnology is already being used to help cure cancer, just not quite in the way your probably thinking. It is possible that one day we will be able to engineer nano robots that can go into the human body detect and destroy cancer cells by themselves but for now they use nanotechnology in their other tools to refine their ability to map out and treat cancerous regions. Nanotechnology allows accurate readings to made of tissue. Then nanoparticles then can be used to specifically target cancer cells minimizing damage to other tissue.

How are nanobots defined? What makes them different from nanoparticles or even proteins?

Thank you for this question! Finally someone who might understand that “nanobot” is basically a popular buzzword that has little to no real meaning!

I guess people have idea of nanobots as small robots moving individual molecules/atoms. This idea has been popularized by some sci-fi books, movies, shows.

The idea of “nanobot” is based on the fact that we have seen molecular devices being used in cells (how some things are operated in unicellulars, like “flagelum”). We realized that some molecules offer “moves” conformation upon charge redistribution, upon illumination… So that we know that we can make moving parts on molecular level.

But of course sci-fi authors took this idea and forgot about details. Like quantum mechanics, like thermodynamics…

So…

Nanoparticle is a small piece of “normal” material. An atom/molecule has some properties. That average if you have huge quantity of that material. (An silicon atom has different properties then silicon chunk.) Sure, you must now get the idea that if you have two atoms, they will behave similar to one. Three atoms might start to show more differences… And there must be some “grey” area where you have no more behaviour typical for individual atoms, but you have not yet the behaviour of huge chunk. That is the realm of nanoparticles.

Thanks to this they allow us to have materials and properties based on those effects that emerge only at the boundary of molecules and bulk.

A protein… is basically a nanobot. If we ever produce nanobots they will be quite similar in a lot of things to how proteins, RNA, DNA things work. The similarity will be about the same as knives are similar to claws or teeth. One is natural thing, the other is man made, but for the same purpose. but both need to deal with the same problems.

What are the sources of nanoparticles?

For clear understanding, the term “nano” is one billionth of one. So any material with dimension of 1cm, reduced into a billion equal parts in any dimension, then one part is 1 nanometer (nm). Particles ranging from 1 nm to 100nm are considered as nano materials.

By sources, do you mean where can we find nano materials! The answer would be “Entire universe” because our universe is nothing but chemically composed matter/antimatter. Atoms of every element are less than the nm range.

How do we make them ?

There are many number of methods and techniques to make nanomaterials. Divided into two basic techniques namely Physical and Chemical techniques attributed to the methods they use in exfoilation or growth of nano materials.

There is also other approaches to make nano materials; Top-down and Bottom-up approaches.

As the name suggests, in Top-down approach, bigger particles are reduced into nano particles by the usage of physical and chemical techniques and Bottom-up approaches makes use of nanomaterials to make bigger materials using chemical and physical techniques.

The application area of nanomaterials are unlimited ranging from electronics, optics, mechanics, communications, biological, medical, pharmaceutical, physical training, energy, storage, battery, water purification, DNA science, etc. This potential for nanomaterials is achieved due to their peculiar change in physical and chemical properties in due to but not only their change in size and surface area.

What is a nano carbon?

Natural carbon can exist in two very different types and is know to everyone: graphite and diamond. Three additional forms of carbon that were discovered between 1985 and 2004 have caused the current excitement among researchers about carbon nanomaterials – fullerenes, nanotubes, and graphene.
