Even with gels and dressings, burns are still a therapeutic problem. Especially when the burn site is in the joint area of ​​the body, the curved skin is difficult to be bandaged. Researchers at Tokai University in Japan have developed an ultra-thin material that is close to the skin to handle those tough wounds and is effective against infectious bacteria.
The researchers said that the material is somewhat similar to cling film, has a flat surface does not require any adhesive, and can fit irregular surfaces, play a role in band-aid and gauze curl. This material is made of biodegradable polylactic acid. Researchers place the material in a test tube filled with water and perform centrifugation, which causes the material to break into smaller pieces. This is then repeated, and the liquid is poured onto a flat surface and the material is allowed to dry. These broken pieces will coalesce together to form a nano-film.
The team found that this nanofilm can fit on uneven surfaces and even fit tiny wrinkles. Later they discovered that this film could protect the burn wounds from infection, and it could prevent the entry of Pseudomonas aeruginosa, a pathogen that usually causes skin infections. The film can be used for three days, and researchers hope that this material can change the way burns are treated, which will help prevent infections and reduce the frequency of dressing changes. The experimental team is currently planning to test large animals.
An excavator auger is a drilling attachment that is used with an excavator to bore holes in the ground. It is typically used in construction, landscaping, and agriculture for tasks such as installing fence posts, planting trees, and drilling for soil samples. The auger consists of a rotating drill bit that is attached to a shaft and powered by the excavator's hydraulic system. The excavator operator controls the speed and direction of the auger, allowing for precise drilling in various soil types and conditions. Augers come in various sizes and styles, including rock augers for drilling through tough terrain.
