ZJU students shine at 17th Challenge Cup

[Editor’s Note: Recently, the 17th “Challenge Cup” National College Students’ Extracurricular Academic Science and Technology Contest drew to a close at Sichuan University. A total of 9,371 students from 555 institutions of higher learning across China participated in this year’s “Challenge Cup”. With 2 grand prizes, 3 first prizes and 1 second prize, Zhejiang University ranked 2nd in overall score nationwide. What’s more, it won the “Excellent Cup” and the Outstanding Organization Award. Read on to find out more about the ZJU winning projects.]

Grand Prize Projects

The Variable Ultra-wide-format Multi-media Printer

GoPrint is an undergraduate entrepreneurial project that provides intelligent mobile printers that can turn users' ideas into visible and tangible entities at any time. CHEN Tianrun, the founder of the project, is an undergraduate student in the College of Information Science & Electronic Engineering. This project has received extensive coverage in CCTV NEWS, People’s Daily, China Youth Daily, The Paper, and Zhejiang News. It is described as “innovative,”, “cool,” and “an invention in the dormitory.”

The Dental Jaw Architect

To address the practical problem with the reconstruction of oral-maxillofacial bones in clinical practice, this project develops a joint reconstruction technology based on 3D vascularized tissue engineering bones and integrated bionic dental implants. It cracks a series of hard nuts, such as ischemic necrosis due to poor blood supply in maxillofacial bone reconstruction and neurovascular defects because of the complex structure of dental implants. It can reconstruct maxillofacial bones in a minimally invasive and efficient manner by producing bionic dental tissues. This project aims to resolve major health problems and improve the well-being of humanity. 

First-prize Projects

The Smart Vesicle

This project is about an autologous smart nano-vesicle therapy. Through the nano-vesicleization of autologous cells, the engineering of targeted vesicles, and the controlled release of vesicles, this therapy can repair tissue damages in a safe, precise and efficient way. It has been applied to repair difficult-to-heal wounds, such as the diabetic foot ulcer, and achieved ideal results.

The Super-power Heart

On the strength of the innovative achievement in arrayed pore-pore materials, this project realizes the super-capacitor energy storage featured by high-power density, long cycle life and low-temperature adaptability. The super-capacitor energy storage equipment plays an exemplary role in the energy recovery of port gantry cranes, thereby helping to achieve the carbon peak and neutrality targets.

No Congenital Heart Children Left Behind

Under the guidance of the “Healthy China 2030 Blueprint”, the team conducts an in-depth investigation of the status quo of the prevention and control of congenital heart disease in China through literature review, questionnaires, interviews and field visits. On this basis, it upgrades the collaborative and innovative network, develops novel screening technology, improves the congenital heart education system, and establishes an integrated pattern combining government, hospitals and charities. This project aims to improve the prevention and control of congenital heart disease nationwide. 

Second-prize Project

Algorithm for Optical Coherence Tomography Angiography in Multi-dimensional Space

Optical coherence tomography angiography (OCTA) can be used to diagnose vascular diseases and predict potential cardiovascular diseases. In OCT, random noise affects the extraction of blood flow signals and thus the effective diagnosis of certain diseases. Against this background, the team constructs an algorithm for OCTA in multi-dimensional space which can improve the contrast of blood flow by 36%, thereby improving the efficiency of clinical diagnoses.
