A camel skin gel that can keep food and medicine cool

  BOSTBUN: Scientists have taken advantage of nature's secrets by revealing many secrets, and now a camel-skin-style hydrogel has been developed that can keep medicines and food cool for days without electricity.

The thin membrane of the gel acts like the skin of a camel and provides insulation for many days, due to which the contents can be kept in cold temperature for many days even without electricity.

The hydrogel is being worked on in laboratories around the world. These water-filled substances are either keeping the wound moist, discharging the medicine or giving the goods a lower temperature. Due to the water, it slowly releases moisture without any electrical energy. 

But this effect soon wears off and experts want the hydrogel's moisture and cooling time to be extended. Now that they have considered camel skins, scientists have dreamed of a long-term cold hydrogel. Jeffrey Grossman of the Massachusetts Institute of Technology (MIT) and his colleagues first studied camels carefully to keep them cool in the scorching heat. Then they looked at its skin and found it in two layers. 

He then tried to simulate this process, first by making a hydrogel and then placing it in another thin aero gel, but by making a microscopic hole in the second layer through which water kept coming out. In this way, the double-layered hydra-gel acts exactly like camel skin The first hydrogel acts in the camel's body like a sweat gland, meaning it evaporates water and keeps itself cool. 

But on top of that, another airy airgel acts like a camel's skin. This provides great insulation, water is lost slowly and the contents can be kept cool for a long time without any electricity. In other words, in this process, the dual system of evaporation and insulation is working at the same time. 

When tested in the laboratory, it was found that the hydrogel and aerogel items can stay up to seven degrees Celsius colder than the rest of the environment. Ordinary hydrogels, on the other hand, cannot do this, nor can they stay cool for long. Interestingly, wrapping an aerogel sheet in just one hydrogel gives 250 hours of cooling, which is enough for ten days. 

During this time the food can be kept cold, the vaccine can be delivered from one place to another and the medicine can be kept at the right temperature in poor areas.
