As much as a third of the world’s populationdoes not have access to clean drinking ラーメンベット 入金不要ボーナス 出金, according to some estimates, and half of the populationcould live in ラーメンベット 入金不要ボーナス 出金-stressed areasby 2025. Finding a solution to this problem could save and improve lives for millions of people, and it is a high priority among scientists and engineers around the globe.
Scientists and engineers at The University of Texas at Austin have created a hydrogel tablet that can rapidly purify contaminated ラーメンベット 入金不要ボーナス 出金. One tablet can disinfect a liter of river ラーメンベット 入金不要ボーナス 出金 and make it suitable for drinking in an hour or less.
“Our multifunctional hydrogel can make a big difference in mitigating global water scarcity because it is easy to use, highly efficient and potentially scalable up to mass production,” said Guihua Yu, an associate professor in the ラーメンベット 禁止ゲーム of ラーメンベット 入金不要ボーナス 出金’s Walker Department of Mechanical ラーメンベット 入金不要ボーナス 出金 and Texas Materials Institute.
Yu and his team recently published their findings in the journalAdvanced Materials.
Today, the primary way to purify ラーメンベット 入金不要ボーナス 出金 is to boil or pasteurize it. But that takes energy, plus a lot of time and work. That isn’t practical for people in parts of the world without the resources for these processes.
The special hydrogels generate hydrogen peroxide to neutralize bacteria at an efficiency rate of more than 99.999%. The hydrogen peroxide works with activated carbon particles to attack essential cell components of bacteria and disrupt their metabolism.
The process requires zero energy input and doesn’t create harmful byproducts. The hydrogels can easily be removed, and they don’t leave any residue.
In addition to purifying ラーメンベット 入金不要ボーナス 出金 on their own, the hydrogels could also improve a process that has been around for thousands of years — solar distillation, the use of sunlight to separate ラーメンベット 入金不要ボーナス 出金 from harmful contaminants via vaporization.
Solar distillation systems often run into issues of biofouling, the accumulation of microorganisms on equipment that causes it to malfunction. The bacteria-killing hydrogels can prevent this from happening.
“A highly vigilant graduate student, Youhong Guo, discovered these hydrogels unexpectedly while doing something else, that is purification of water with sunlight,” said Keith Johnston, a professor in the McKetta Department of Chemical ラーメンベット 入金不要ボーナス 出金 who co-led the project.
The team is working to improve the hydrogels by increasing the different types of pathogens and viruses in ラーメンベット 入金不要ボーナス 出金 that they can neutralize. And the team is also in the process of commercializing several prototypes.
Scaling up the hydrogels would be straightforward, the researchers say. Materials for making them are inexpensive, and the synthesis processes are simple and remain that way at large scales. And they can easily control the shape and size of the hydrogels, making them flexible for different types of uses.
Youhong Guo, a graduate student in Yu’s lab, is the first author on the paper. Graduate students Christopher Dundas from chemical ラーメンベット 入金不要ボーナス 出金 and Xingyi Zhou from mechanical ラーメンベット 入金不要ボーナス 出金 were also part of the team. The research was supported by grants from the Energy Institute at UT Austin and the Dreyfus Foundation.
