Recent developments in nanoscale electronics
allow current wireless technologies to function in
nanoscale environments. Especially due to their
incredible electrical and electromagnetic proper-
ties, carbon nanotubes are promising physical
phenomenon that are used for the realization of
a nanoscale communication paradigm. This pro-

tions such as collaborative disease detection with
communicating in-vivo nanosensor nodes and
distributed chemical attack detection with a net-
work of nanorobots. Hence, one of the most
challenging subjects for such applications
becomes the realization of nanoscale ad hoc net-
works. In this article, we define the concept of
carbon nanotube-based nanoscale ad hoc net-
works for future nanotechnology applications.
Carbon nanotube-based nanoscale Ad hoc NET-
works (CANETs) can be perceived as the down-
scaled version of traditional wireless ad hoc
networks without downgrading its main function-
alities. The objective of this work is to introduce
this novel and interdisciplinary research field and
highlight major barriers toward its realization.

We have presented the integration of a wireless simulator called
Vouivre in DPRSim, a simulator for modular robots. The major
challenge we faced was the difficulty to integrate three parts that have
different timing requirement: physical (ODE), DPRSim and Vouivre.
This has been solved by using and managing three timelines. Vouivre
has been designed as a library and can therefore be integrated in
others simulators. Furthermore, integrating it in DPRSim gave us
an experience which can be reused. Experiments have shown that
Vouivre is easy to use and that wireless integration in MEMS modular
robots could be useful for various kind of applications either for
extending the communication possibilities, with the distributed walker
scenario, or by optimizing communication times, with the broadcast
algorithm. Our next step will now be to integrate in Vouivre the
nanowireless channel model developed in.
В епоху холодної війни існувало дві великі конкурентоспроможні дослідницькі групи, які виготовляли детектори гамма- та нейтронного випромінювання (сенсори): Група напівпровідників Національної лабораторії імені Лоуренса Берклі та Міністерство середнього машинобудування СРСР (включало Інститут атомної енергії імені І. Курчатова, Державний інститут рідкісних Метали – Гіредмет, Інститут радіаційних технологій та приладів та ін.). Обидва конкуренти були зосереджені на розробці напівпровідникових детекторів ядерного випромінювання та їх застосування. Найкращим сенсорним матеріалом для датчиків гамма-випромінювання був і залишається ультрачистий Ge і Si або Ge, легований домішками Ga з концентрацією акцептора до 1016 см−3.
Нині, у зв’язку з питаннями нерозповсюдження ядерної зброї та міжнародної безпеки, створено нові та значно суворіші вимоги до датчиків ядерного випромінювання та сенсорних систем. Проблема розробки нових датчиків, які відповідають новим вимогам, ставить перед дослідниками та інженерами цікаві технічні проблеми. Нові датчики повинні покладатися на один або кілька сенсорних механізмів і створювати сигнал, який вказує на значення ядерного/іонізуючого випромінювання.

3. #A Carbon Nanotube is a tube-shaped material, made of carbon, having a
diameter measuring on the nanometre scale.
#Carbon Nanotubes are formed from essentially the graphite sheet and the
graphite layer appears somewhat like a rolled-up continuous unbroken
hexagonal mesh and carbon molecules at the apexes of the hexagons.
#Nanotubes are members of the fullerene structural family.
#Their name is derived from their long, hollow structure with the walls
formed by one atom thick sheets of carbon, called graphene.

7. Multi-walled nanotubes (MWNT) consist
of multiple rolled layers (concentric tubes)
of graphene.
Interlayer distance :- 3.4 Å
To describe structure of MWNT there are
two models:-
1. Russian doll model
2. Parchment model
8. TORUS:-
It is a carbon nanotube bent in a torus
shape (i.e. doughnut shape)
NANOBUD :-
Carbon Nanobud are created combining
carbon nanotubes and fullerenes.
9. GRAPHENATED CARBON NANOTUBE :-
They are new hybrids that combines graphitic foliates grown along the
sidewalls of MWNT.
NITROGEN DOPED CARBON NANOTUBE :-
These are used for enhancing storage capacity of Li-ion batteries.
N-doping provides defects in the walls of CNT's allowing for Li ions to
diffuse into inter-wall space.
10. Peapod :-
A carbon peapod is a novel hybrid carbon material
which traps fullerene inside a Carbon nanotube.
CUP-STACKED CARBON
NANOTUBES :-
CSCNTs exhibit semiconducting behaviours due to
the stacking microstructure of graphene layers.
11. Strength :-
Carbon nanotubes are the strongest, flexible and stiffest materials yet discovered in terms
of tensile strength and elastic modulus respectively.
Hardness :-
The hardness (152 Gpa) and bulk modulus (462–546 Gpa) of carbon nanotubes are greater
than diamond, which is considered the hardest material.
Electrical Properties:-
Because of the symmetry and unique electronic structure of graphene, nanotube has a very
high current carrying capacity.
12. Thermal Conductivity:-
All nanotubes are expected to be very good thermal conductors along the tube.
EM Wave absorption:-
There has been some research on filling MWNTs with metals, such as Fe, Ni, Co,
etc., to increase the absorption effectiveness of MWNTs in the microwave regime.
Thermal properties:-
All nanotubes are expected to be very good thermal conductors along the tube, but
good insulators laterally to the tube axis.
14. Toxicity:-
Under some conditions, nanotubes can cross membrane barriers, which
suggests that if raw materials reach the organs they can induce harmful effects
such as inflammatory and fibrotic reactions.
Crystallographic defect:-
As with any material, the existence of a crystallographic defect affects the
material properties. Defects can occur in the form of atomic vacancies.
15. There are three methods using which we can produce carbon nanotubes.
