Material and Polymer
Electrochemical Impedance Analyser
It can be used to define reaction mechanism and physical structures involved in a wide variety of electrochemical applications including:
- Battery and fuel cell
- Surface structures
- Corrosion processes
- Biological systems
It can be used to deposit uniform thin films (some micro metre to 1mm) to flat substrates (~150 mm wafer in diameter or ~125 mm square substrate). Usually, the first steps of this operation are to place the substrate into the spin coater and to apply a small volume of coating material onto the center of the substrate. The spin coater then rotates the substrate at high speed, which results in the uniform thin film of the coating material on the substrate surface due to the centrifugal force. This operation is carried out under a fume hood because the coating material is usually volatile. Maximum spin speed: 12k RPM.
We have a Sonic Vibra-Cell in our lab. It can safely process a wide range of organic and inorganic materials – from microliters to litres. Typical applications include: sample preparation, dispersion, homogenization, particle size reduction, nanotechnology (including nanoparticle and Graphene dispersion), and acceleration of chemical reactions, degassing and atomization.
Field emission scanning electron microscopy
A scanning electron microscope [Hitachi SU-70 FE SEM (field emission scanning electron microscope) is being used to study the morphology of the composite films. The technique involves scanning an electron beam across the sample surface and secondary electrons are ejected from the surface. When interacted with a solid, secondary electron images are generated by synchronizing the optical output of the detector system with the raster of the electron probe across the solid surface. SEM images are used to examine the surface morphology and fracture cross section.
Differential Scanning Calorimetry (DSC)
Differential Scanning Calorimetry (DSC) is the most-employed Thermal Analysis method. NETZSCH DSC instruments work according to the heat flow principle and are characterized by a three-dimensional symmetrical construction with homogeneous heating. Sensors with high calorimetric sensitivity, short time constants and a condensation-free sample chamber in the calorimeter cell guarantee high detection sensitivity and stable, reproducible baselines over the entire life cycle of a calorimeter: ideal qualifications for successful application in research and academia, materials development and quality control.
