In the Electrical Machines Lab students apply their fundamental knowledge acquired from theory and build circuits on the test panels. The circuit being built is a variable speed drive as it would be used in industry.
Also in the Electrical Machines Lab is an automatic resistance starter. Because students are working with 380 volt circuits the lecturer can lock out the circuit until the circuit has been tested for correctness. Only then can the power be applied to the circuit. Safety features include an earth leakage, emergency stop, and a key which can lock out the supply.
Leslie Nickola optimises a motor control circuit in the Electrical Machines Lab.
Situated in the Plant and Automation laboratory is a manual process plant. Two of the tanks are part of the refrigeration plant. The other three are mixing and heating plants. The projects are to automate parts of the plant. Students are required to design and physically build the circuits they design to automate the process plant.
The focus of alternative energy research is on solar thermal systems for small and large buildings, with more emphasis on storage of thermal energy, high solar fraction building and optimisation and control of solar heat for industrial applications.
The purpose of the cutting machine is to cut rocks. Rocks are cut to ensure the right core length for rock testing.
This is a pneumatics system. Pneumatics refers to the science or devices related to the movement and phenomena of air. An air compressor converts the mechanical energy of the prime mover into, mainly, pressure energy of the compressed air. The compressed air is stored in compressed air reservoirs and transmitted through transmission lines: pipes and hoses. The pneumatic power is controlled by means of a set of valves such as the pressure, flow, and directional control valves. Then, the pressure energy is converted to the required mechanical energy by means of the pneumatic cylinders and motors.
Postdoctoral Fellow Dr Sweety Sarma explains that the SynthWAVE machine is an improved microwave synthesis system with single reaction chamber (SRC) technology in a fully automated bench top reactor. The system is used in nanomaterials, drug discovery, fine chemicals, polymers and catalysis research.
The Chirascan circular dichroism spectrometer is used to study biomolecular characteristics, mechanisms and interactions.
A liquid chromatography system is used to separate a sample into its individual parts. This separation occurs based on the interactions of the sample with the mobile and stationary phases.
Freeze drying samples is a low temperature dehydration process which involves freezing the product, then reducing pressure and adding heat to remove the ice by sublimation.
The Gas Chromatography-Mass Spectrometry (GC-MS) instrument is able to identify different substances within a test sample
A scanning electron microscope (SEM) can magnify a sample by as much as 2 million times, and has the power to help visualize the finest detail on any sample
Sensitive scientific reagents, kits and samples can be stored in a specialized -80 degrees freezer
A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum, which is widely used for analysis of sample materials
The live cell imaging system is utilized in the study of living cells through time-lapse photography
