The E24 electric formula racing car designed by Racing Car Studio of SZTU adopted a four-motor drive system, which passed the mark of four seconds of 0-100 km/h acceleration. When the overall weight of the transmission structure is fixed, the system can greatly improve the stability of the racing car in the extreme driving state. In 2022, the team won the National Second Prize and Third Prize when participating in the Formula Student Electric China for the first time; and won the National First Prize and Second Prize in the 17th National University Students Smart Car Race (Outdoor).

Distributed control governed by partial differential equations (PDEs) can ensure the stability of the UAV fleet performance and avoid collisions. A large scale of drones can be controlled by limited data interaction. The team can give full play to the advantages of domestic independent operating systems and have better control of more drones based on the drone performance plan using the open-source Harmony operating system.

The research team found that Turing patterns can also be generated in an uphill-diffusion system without a chemical reaction process. The experimental system forms a simple dissipative structure that could generate patterns in natural conditions without artificial involvement and orderly and various patterns can be found in the biosystem. The research may pave a new way in developing self-assembling techniques of micro/nano structured materials and provide a new perspective for the understanding of biomorphic structures.

The work was published in Nature Communication (IF: 17.694) titled “Turing patterns with high-resolution formed without chemical reaction in thin-film solution of organic semiconductors”. The article can be found at: https://www.nature.com/articles/s41467-022-35162-z.

SZTU researchers have studied the dynamics and evolution of the current filaments with their transverse dimension on the order of the skin depth ≪0.1 μm based on their three-dimensional particle-in-cell simulations. The research revealed the existence of a new regime of high-current electron beam transport in solid-density plasma, where the relativistic electron beams (REBs) can break up into nanoscale electron bunches by self-excited strong oscillating transverse electrostatic fields. Understanding such process underpins many novel applications of high-power lasers.

The findings were published in Physical Review Letters (IF:9.161) titled “Nanoscale Electrostatic Modulation of Mega-Ampere Electron Current in Solid-Density Plasmas”. The article can be found at: https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.127.245002.

Researchers demonstrated a fundamentally new strategy for ultrasensitive detection based on color-switchable lasing with a cavity-enhanced reduction of limit of detection (LOD). The research proposed a novel ultrasensitive detection approach based on microsphere cavities formed by bio-compatible polystyrene (PS) mixed with dyes, penetrated by biomarker molecules when submerged in the biomolecular solution. When biomarkers interact with the chemo-responsive dyes, intramolecular charge-transfer modifies the electronic structure of dyes, resulting in the shift of emission wavelengths, thereby realizing qualitative detection of biomarkers with the naked eyes. The approach will offer exciting future opportunities for biomedical detection and early diagnostics to reduce the mortality rate of fatal diseases.

The research results were published in the interdisciplinary premium journal Advanced Science (Q1, IF: 16.806) titled “Ultrasensitive Detection of Biomarkers in a Color-Switchable Microcavity-Reactor Laser”.
