The Laboratory Unit of
Nanoengineering & Nanotechnology (NanoLab) is situated at the School of
Chemical Engineering (Department of Materials Science and Engineering) of
National Technical University of Athens (NTUA). It was established in 2006 and
the research group mostly focuses on the study and analysis (mathematical
modeling) of the nanomechanical properties of materials (soft matter, metals,
ceramics, polymers, thin films and coatings). The group is also working on the
synthesis and characterization of nanostructures, nanostructures degradation
and drug absorption delivered by nanoparticles and the mathematical modeling of
cancer invasion. NanoLab research activity aims to interact with Academia,
Research Institutes and Organizations and Industry, produce new materials and
knowledge, and transfer its technology to scientific and industrial users,
through National and European funding projects. Moreover, the group provides
excellent care of under - graduated and post - graduate students.

– SPM Testing
testing is performed with a nanomechanical test instrument, which allows the
application of loads from 1 to 30,000 μN and records the displacement as a
function of applied loads with a high load resolution (1 nN) and a high
displacement resolution (0.04nm). The nanomechanical test instrument employed
in this study is equipped with a Scanning Probe Microscope (SPM), in which a
sharp probe tip moves in a raster scan pattern across a sample surface using a
three-axis piezo positioned (clean area environment with 45% humidity and 23°C
ambient temperature through proper air-managing instrument). In order to
operate under closed loop load or displacement control, feedback control option
is used. In nanoindentation measurements, various types of tips are used
(standard three-sided pyramidal Berkovich probe, Vickes, spherical,
conospherical, fluid tip etc.). Nanotribological studies are also performed.
. Load vs displacement as the tip approaches the surface and snaps into contact
because of surface forces and types of scratches.
Chemical Vapor Deposition (Thermal CVD) (synthesis of CNT, SiC)
of CNTs and nanographite is obtained by CVD of a gas mixture evaporated from
catalyst powder and a solid carbon source. Deposition was carried out at
different temperatures on crystalline silicon substrates.
2. Sketch of the thermal-CVD reactor system.
CVD reactor (Fig. 1) consists of a horizontal quartz tube (100 cm long, 4.2 cm
in diameter) housed in a cylindrical furnace 60 cm long. Inside the tube, a
constant nitrogen gas flow of approximately 420 ml/min is maintained at
pressures slightly above the atmospheric pressure, in order to provide the
condition for a laminar gas flow. A pyrex flask containing the reagent mixture
is connected, via a T-joint, to the tube close to the nitrogen inlet. A heater
plate is located below the flask.
