Scientists from Changsha University of Science & Technology recently developed an eco-friendly snow melting agent with strong durability.
The snow melting agent, or anti-freeze?material, is a new type of road spraying?or brushing material,used to?form a functional layer on a road to prevent icing.
Usually, snow melting agents can be divided into chlorides and non-chlorides.?At present, the mainstream snow removal agent on the market is chloride, which is not sustainable as it?corrode metal equipment and pollutes the environment.
By lowering the freezing point of ice, the research team discovered a new liquid snow melting agent.?Experimental tests?show that at around?0℃,?this agent can melt?the ice in five?minutes, while the traditional snow melting agent will take several hours.
Additionally, under the constant temperature of -25℃, it can maintain a non-freezing state for more than six months, proving its strong durability.
The trio will conduct a series of experiments in fields such as life science, fluid physics, combustion science and materials science. Notably, this is the first time that fruit flies have been taken on a Chinese space mission as experimental subjects. What made scientists choose fruit flies? What experiment will they undergo?
