“…Ice accumulation on surfaces can lead to severe safety accidents and substantial economic losses on vessels, offshore platforms, aircraft, wind turbines, and roads. − In polar regions or extreme environments with ultralow temperatures (≤−30 °C), the icing issue is very severe. Various traditional deicing methods have been proposed and developed for practical anti-icing, including chemical deicing, mechanical deicing, and heating deicing. − Nevertheless, environmental pollution and high energy consumption continue to hinder their development. − …”

Materials with low ice adhesion and long-lasting antiicing properties remain an ongoing challenge in ultralow temperature environments (≤−30 °C). This study presents a gel material consisting of a polymer matrix (copolymer of polyurethane and acrylamide) and an anti-icing agent, ethylene glycol (EG), designed for anti-icing applications at ultralow temperatures. The surface shows a prolonged droplet freezing delay of ca. 322 s at −30 °C and frost resistance properties. It also exhibits an ice adhesion strength of 1.1 kPa at −10 °C and 39.8 kPa at −50 °C, resulting from the interaction between EG and water molecules that hinders the crystallization of ice as well as the significant mismatch between elastic gel and ice. In addition, the gel surface exhibits favorable anti-icing durability, with an ice adhesion strength below 20.0 kPa after 25 icing/deicing cycles and mechanical scratch tests. The gel demonstrates remarkable thermal durability, achieved through the H-bonds between the EG and polymer matrix. The H-bonds further enhance the anti-icing performance, thereby remarkably decreasing EG depletion and improving anti-icing durability. Overall, these properties suggest the potential application of this gel material in harsh environments including polar regions.

“…Ice formation and accretion are natural phenomena that particularly take place in cold-climate countries and in both hemispheres [1]. Icing and ice accretion can cause serious safety and economic challenges that affect almost all life sectors such as infrastructure [2]; transportation and cargo [3]; power production, power lines and communication; wind turbines [4]; ships and marine vessels [5]; aircraft [6]; and many freezers and commercial and residential refrigerators [7]. Sustainable solutions are needed to tackle these challenges.…”

Icing and ice accretion cause severe problems in different industrial sectors, e.g., in aircrafts, aviation traffic, ships, solar panels, and wind turbines. This can lead to enormous economic losses and serious safety issues. Surface engineering can tackle these problems by designing surface structures to work as icephobic coatings and, this way, act as passive anti-icing solutions. In this research, slippery liquid-infused porous structures were fabricated using flame- and cold-spraying to produce polymer (LDPE and PEEK) coatings, and impregnated with a silicone lubricant. Microstructural details, surface properties, wetting behavior, and cyclic icing–deicing behavior were evaluated via ice adhesion measurements, which show the potential performance of SLIPS designs. All these SLIPS showed low or medium-low ice adhesion after the first icing-deicing cycle and the best candidate showed stable performance even after several icing-deicing cycles.

“…With the opening of Beijing Tianjin inter-city high-speed railway, and other high-speed passenger dedicated lines such as Shijiazhuang-Taiyuan, Wuhan-Guangzhou, Zhengzhou-Xi'an, Beijing-Shanghai and Guangzhou-Shenzhen-Hongkong, high-speed railway [1][2][3][4][5] is developing rapidly. For metro, Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Chengdu and other cities have been operating in succession, China has made great progress in high-speed railway and urban rail transit [6][7][8][9][10][11] in recent years. At the same time, the State Council of China discussed and passed the '12th Five-Year' comprehensive transportation system plan on 21 March 2012.…”

In this work, multi-function vehicle bus (MVB) controller-based Field Programmable Gate Array (FPGA) and MVB manager based on the real-time multitasking operating system were explored and developed. The function of the MVB controller data link layer was realised by using FPGA. The embedded real-time multitasking operating system uCOS-II was applied to the development of MVB manager’s processing data, device state management, message data and bus management function. The network consistency test was performed to validate data communication of MVB link layer control protocol and the management function of MVB manager; the equipment was shown to be compatible with each other and met the requirements of IEC61375-1.
