Recently, a new batch of scientific research projects that the Cambridge University - Nanjing Centre of Technology and Innovation (CUNJC) planned to introduce from the University of Cambridge have successfully passed the review of authoritative experts, and were approved by the academic committee and the board of directors of the Centre.  The newly introduced cutting-edge research projects are another batch of projects following the first batch of projects landed in the Centre, which will greatly promote the academic innovation, talent gathering, and outcome transformation of the Centre.


The Review Meeting


There are a total of three projects introduced in this batch: "DropBioApp Engineering droplet-based microfluidic platform for biological applications", "Holographic interferometer for 3D surface profiling", and "High power density DC converters of 48V power supply systems used for datacentres ".


DropBioApp Engineering droplet-based microfluidic platform for biological applications


Led by Professor Chris Abell, Pro-Vice-Chancellor (Research) of Cambridge University, the project relies on the Centre , and will build up a set of microfluidic facilities for the Centre including a microfluidic device fabrication workstation, a fluorescence detection rig, and microdroplet sorting capability. This can be used for microdroplets generation, materials synthesis, cell encapsulation, fluorescence sorting, etc. 


 Professor Chris Abell


The project will form a unique single-cell sequencing method based on microfluidic technology, the preparation technology of functional medical microspheres, and a prototype that realizes the integration of high-throughput microfluidic screening, etc., transiting from a research-scale microfluidic technology to industrial-scale manufacturing and production, and will cooperate with local companies in the fields of biomaterials, single-cell analysis, drug discovery and tissue engineering to establish a formal biotechnology business entity with an aim to use the research results for commercial purposes.


Holographic interferometer for 3D surface profiling


Led by Professor Daping Chu, Chair Professor of Cambridge University, Director of Cambridge Centre for Advanced Photonics and Electronics (CAPE) and the Centre for Photonic Devices and Sensors, the project relies on the Centre to explore the integration of pure phase liquid crystal on silicon (LCOS) technology into the interferometer to relax the tolerance of its hardware optical system, which is compensated by computer-generated holograms, thereby reducing equipment costs.

The architecture proposed in this project will be able to use low-cost optical and optomechanical components without affecting system performance. In addition, the generated interferogram will also become less complex and can be processed at high speed. The research result of this project is expected to be widely applied to various surface inspection scenarios in scientific research and industrial production, such as optical component inspection, integrated circuit inspection, micro-electromechanical device inspection, and biological cell inspection.


High power density DC converters of 48V power supply systems used for datacentres


Led by Dr Long Teng, Lecturer of Cambridge University, the project relies on the centre and proposes a new type of DC-DC converter topology and its derivative structure, especially suitable for 48V DC power supply system. This structure improves the power density by at least 50% compared with the current switched capacitor structure, especially in the application scenarios of high voltage conversion ratio. 


Dr. Long Teng


The increased power density can greatly reduce the size of the converter and make the converter closer to the processor (CPU or GPU) in the layout position, and effectively reduce the transmission power loss. Efficient 48V DC-DC converter is the core technology of 48V DC power supply. In the future, the power supply system of the data centre using 48V DC power supply will reduce energy consumption by more than 7% compared with traditional data centres.
