Bengbu City’s Parking: A Policy (Re)Design Project

INTI JOURNAL. (2020)

Yang Xiangqian Haolin Wang Jingjing Wang WU Hua-ming Guoxin Ma

In developed countries, parking has been a widespread problem for a long time. In China, its growing population has put its public transportation system under a lot of pressure, with the increasing car ownership in its big and small cities expanding the size of urban centres which in turn increases the demand for faster movement and mobility. As researchers based in Bengbu, a city in Anhui province, China, we observe that presently the phenomenon of disorderly parking and traffic congestion on urban roads is serious in the city. Recruited by the local government, we propose a project on policy (re)designing for Bengbu’s on-street parking in particular, and parking management in general. This paper provides a background and positioning of the proposed project, summarising its viewpoints and recommendations for policy-making.

Preparation of Sulphoaluminate Cement Clinkers from Wet Flue Gas Desulphurized Slag

Environmental Science & Technology (2010)

Haolin Wang

Sulphoaluminate cement was prepared at 1250℃ using wet flue gas desulphurized slag,limestone,limonite and bauxite as major raw materials by designing mineral phase composition. Formation mechanism of cement clinker and mineralogical phase composition of hydrated product were investigated by XRD and SEM. Results showed that the essential mineral phases of cement clinker were C4A3S and C2S. Mechanical strength tests indicated that the maximum compressive strength of sulphoaluminate cement was 44.3MPa,54.1MPa and 67.5MPa at 1d,3d and 28d respectively,and compressive strength increased steadily during the curing time. Hydrated products were mainly needle-like or fibrous Aft.

Improved portable wireless remote control quadcopter

7th International Symposium on Advances in Electrical, Electronics, and Computer Engineering (2022)

Fei Gao Wei Wang Haolin Wang Shuaibo Wang

A portable small wireless remote-control quadcopter is designed and realized in this paper. The main control module is designed by the microcontrollers based on the STM32s, and by using automatic control and digital wave filtering technologies. The wireless remote-control function is realized through the wireless radio frequency module. The motor control is realized by the motor drive circuit based on the MOSFETs, through our improved quaternion posture solution algorithm. The sensor circuit, composed of MPU6050 and BMP280, realizes more accurate posture and height control. The user operation control and data acquisition/processing are realized by the analog-digital (A/D) conversion module on the microcontrollers. After debugging and testing, the system finally realizes the flight function, it includes wireless remote control, two-way data interaction, front and rear, left and right movements, and speed control. It has the advantages of small size, light weight, and low cost. It is suitable for outdoor flight operation environment.

General synthesis of metal oxide hollow core–shell microspheres as anode materials for lithium-ion batteries and as adsorbents for wastewater treatment

CrystEngComm (2017)

Yuanxiang Gu Haolin Wang Yuxue Xuan Lei Wang Yi Qian

Hollow core–shell structures have many advantages, but their synthesis remains challenging. In this report, we demonstrate a general method for the preparation of a series of metal oxide hollow core–shell microspheres, including Co3O4, NiO and Mn2O3. The hollow core–shell microspheres were prepared via a coordination precipitation route followed by a calcination process. The morphology and microstructures of the metal oxide hollow core–shell microspheres could be controlled by optimizing the experimental conditions. A possible formation mechanism of the hollow core–shell structure was proposed. As anode materials for lithium ion cells, the Co3O4 hollow core–shell microspheres exhibited superior Li+ storage properties. When applied as adsorbents in water treatment, the NiO hollow core–shell microspheres showed an excellent ability to remove organic pollutants.

What Is the Real Origin of Single-Walled Carbon Nanotubes for the Performance Enhancement of Si-Based Anodes?

Journal of the American Chemical Society (2024)

Haolin Wang Yunfeng Chao Jinzhao Li Qi Qi Junfeng Lu

A large amount of lithium-ion storage in Si-based anodes promises high energy density yet also results in large volume expansion, causing impaired cyclability and conductivity. Instead of restricting pulverization of Si-based particles, herein, we disclose that single-walled carbon nanotubes (SWNTs) can take advantage of volume expansion and induce interfacial reactions that stabilize the pulverized Si-based clusters in situ. Operando Raman spectroscopy and density functional theory calculations reveal that the volume expansion by the lithiation of Si-based particles generates ∼14% tensile strains in SWNTs, which, in turn, strengthens the chemical interaction between Li and C. This chemomechanical coupling effect facilitates the transformation of sp2-C at the defect of SWNTs to Li–C bonds with sp3 hybridization, which also initiates the formation of new Si–C chemical bonds at the interface. Along with this process, SWNTs can also induce in situ reconstruction of the 3D architecture of the anode, forming mechanically strengthened networks with high electrical and ionic conductivities. As such, with the addition of only 1 wt % of SWNTs, graphite/SiOx composite anodes can deliver practical performance well surpassing that of commercial graphite anodes. These findings enrich our understanding of strain-induced interfacial reactions, providing a general principle for mitigating the degradation of alloying or conversion-reaction-based electrodes.

Anonymous Authentication Scheme for Electric Vehicle Reservations in V2G Networks

Xiaohua Yang Haolin Wang Jiahao Li Yun Zhao Ziyang Yang

Vehicle-to-Grid (V2G) technology enables electric vehicles (EVs) to integrate into smart grids (SG), allowing them to charge on a large scale while also supporting their ability to discharge energy to the grid as mobile and distributed storage units. V2G exhibits flexible characteristics, and users have a demand to protect their personal privacy. However, existing V2G network authentication schemes seldom meet both privacy protection and dynamic management requirements simultaneously. This paper presents a secure, efficient, and anonymous dynamic authentication scheme for V2G networks. The scheme allows charging stations to anonymously authenticate EVs and dynamically manage them. Additionally, the proposed authentication scheme incurs a constant time overhead during the verification phase, irrespective of the number of electric vehicles, and EVs do not need to update their member certificates and key pairs before exiting the V2G network. This authentication scheme addresses the unique challenges posed by V2G networks, ensuring real-time monitoring of electric vehicle energy storage capabilities while maintaining dynamic vehicle management with anonymity. The scheme ensures the security and efficiency of V2G networks, thereby promoting the widespread adoption of V2G technology and contributing to the development of SG.
