6 Crazy And Strange Materials And Ideas Developed In A Laboratory

2018-05-23
six crazy and strange materials and ideas developed in a laboratory number one ultra hydrophobic material gentle science has made some great progress in the recent decades in the field of hydrophobicity and opening a wide range of applications ultra hydrophobic surfaces are extremely difficult to wet the contact angles of water droplets and an ultra hydrophobic material exceed 150 degrees this is also referred to as the Lotus effect this effect was discovered in the 1970s from the microscopic observations of the surface of a lotus leaf a droplet impacting on hydrophobic surfaces can fully rebound like an elastic ball research in this field is very advanced in focused and finding a material with the highest level of water repellency to achieve a material extremely repellant which would be a huge help for many industrial fields ultra tech International has partnered with Luna innovations to bring to market a revolutionary new coating Gento is able to achieve the best properties of hydrophobic coatings through complex chemical reactions a sol-gel is a liquid solution that becomes a gel it has flexibility and toughness at the same time almost like a flexible ceramic on the surface of super hydrophobic coatings water will beat up but more importantly water will shed off the surface Gento is actually not super hydrophobic but because of its low sliding angle of less than 5 degrees it sheds blood similarly super hydrophobic s-- due to their structure don't stand up too much abrasion Gento is unlike traditional super hydrophobic coatings with its unique ability not only to repel water most oils and solvents but also with its significant abrasion resistance durability and flexibility number 2 hydrogel hydrogel is a gel polymer network that contains over ninety percent water and the changes its size under the influence of temperature it's composed of small crystals that are able to absorb water 30 to 60 times their own volume the total absorbency in swelling capacity are controlled by the type degree of cross linkers used to make the gel thanks to its amazing water absorption capacity hydro gels are used in greenhouses agricultural nurseries and they are the first biomaterials designed for use in the human body recently there have been several important developments which have broadened the applicability of hydrogel materials the material is also commonly used for medical purposes for tissue engineering current research focuses on the development of hydrogels for cardiac repair chronic wound and burn dressings and 3d bioprinting applications number three nitinol nitinol is composed of nickel and titanium and almost equal proportions it has a special ability to rebound to its original form even after you mold it into different shapes the phenomenon called the memory effect is driven by heat exchanges it is able to repeat this process many times without losing the ability to regain its original shape this material has a wide range of applications in the fields of electronics and mechanics it can also be used in smartphones robotics and medical industries number four methyl gallium gallium metal is one of the least known in the scientific field this strange mysterious metal is very difficult to understand for members of the scientific community gallium is a soft metal which is a brittle solid at low temperatures and liquid at temperatures greater at twenty nine point seven degrees Celsius if you keep it in your palm for just a few minutes your body heat will cause a solid metal to gradually turn into liquid this non-toxic metal is definitely very interesting and has a wide range of potentials but a certainly lachchi 1-kilogram costs $3,000 number-5 aerogel also known as liquid smoke aerogel is a broad term referring to a special group of materials its chemical structure is similar to glass but its density is a thousand times lower since it contains 99% air ingredients thanks to its properties the aerogel is the lightest solid material that exists today despite its very low weight this material is very strong its heat insulation properties have been exploited by NASA engineers NASA used this material in most of its spacecraft to provide heat protection from the Sun aerogel has been used since the early 1960s in space travel but scientists are now finding multiple users such as detection of nuclear radiation absorption of long-lived nuclear waste thermal insulation and detection of harmful microorganisms number six magnetic Thinking Putty like any other putty it can be stretched bounced molded pot and torn however when this but is in the presence of a magnetic field if exhibits fascinating properties this truly amazing magnetic monster can be created by simply adding ferric iron oxide powder to regular silly putty and then it becomes ferromagnetic the unusual magnetic mass interacts with other strong ferromagnetic magnets any other powerful Ferro magnet that gets in the range of the magnetic field of the putty will experience a force that pulls into a region of stronger magnetic strength hit that like button if you enjoyed this video and don't forget
