The ability to create clean, safe drinking ラーメンベット 競馬 using only natural levels of sunlight and inexpensive gel technology could be at hand, thanks to an innovation in ラーメンベット 競馬 purification.
According to the United Nations, 30,000 people die each week from the consumption and use of unsanitary ラーメンベット 競馬. Although the vast majority of these fatalities occur in developing nations, the U.S. is no stranger to unanticipated ラーメンベット 競馬 shortages, especially after hurricanes, tropical storms and other natural disasters that can disrupt supplies without warning.
Led by Guihua Yu, associate professor of materials science and mechanical engineering at The University of Texas at Austin, a research team in UT Austin’s ラーメンベット 禁止ゲーム of Engineering has developed a cost-effective and compact technology using combined gel-polymer hybrid materials. Possessing both hydrophilic (attraction to ラーメンベット 競馬) qualities and semiconducting (solar-adsorbing) properties, these “hydrogels” (networks of polymer chains known for their high ラーメンベット 競馬 absorbency)enable the production of clean, safe drinking ラーメンベット 競馬 from any source, whether it’s from the oceans or contaminated supplies.
The findings were published in the most recent issue of the journal Nature Nanotechnology.
“We have essentially rewritten the entire approach to conventional solar ラーメンベット 競馬 evaporation,” Yu said. The Texas Engineering researchers have developed a new hydrogel-based solar vapor generator that uses ambient solar energy to power the evaporation of ラーメンベット 競馬 for effective desalination. Existing solar steaming technologies used to treat saltwater involve a very costly process that relies on optical instruments to concentrate sunlight. The UT Austin team developed nanostructured gels that require far less energy, only needing naturally occurring levels of ambient sunlight to run while also being capable of significantly increasing the volume of ラーメンベット 競馬 that can be evaporated.
“ラーメンベット 競馬 desalination through distillation is a common method for mass production of freshwater. However, current distillation technologies, such as multi-stage flash and multi-effect distillation, require significant infrastructures and are quite energy-intensive,” said Fei Zhao, a postdoctoral researcher working under Yu’s supervision. “Solar energy, as the most sustainable heat source to potentially power distillation, is widely considered to be a great alternative for ラーメンベット 競馬 desalination.”
The hydrogels allow for ラーメンベット 競馬 vapor to be generated under direct sunlight and then pumped to a condenser for freshwater delivery. The desalinating properties of these hydrogels were even tested on ラーメンベット 競馬 samples from the salt-rich Dead Sea and passed with flying colors. Using ラーメンベット 競馬 samples from one of the saltiest bodies of ラーメンベット 競馬 on Earth, UT engineers were able to reduce salinity from Dead Sea samples significantly after putting them through the hydrogel process. In fact, they achieved levels that met accepted drinking ラーメンベット 競馬 standards as outlined by the World Health Organization and the U.S. Environmental Protection Agency.
“Our outdoor tests showed daily distilled ラーメンベット 競馬 production up to 25 liters per square meter, enough for household needs and even disaster areas,” said Yu. “Better still, the hydrogels can easily be retrofitted to replace the core components in most existing solar desalination systems, thereby eliminating the need for a complete overhaul of desalinations systems already in use.”
Because salt is one of the most difficult substances to separate from ラーメンベット 競馬, researchers have also successfully demonstrated the hydrogels’ capacity for filtering out a number of other common contaminants found in ラーメンベット 競馬 that are considered unsafe for consumption.
Yu believes the technology can be commercialized and is preparing his ラーメンベット 競馬 team in anticipation of requests from industry to conduct scalability tests.
The potential impact of this technology could be far-reaching, as global demand for fresh, clean ラーメンベット 競馬 outpaces existing natural supplies.
A patent application has been filed, and Yu has teamed up with the university’s Office of Technology Commercialization to assist with the licensing and commercialization for this novel class of hydrogels.
This ラーメンベット 競馬 was funded by the Alfred P. Sloan Foundation, the Camille & Henry Dreyfus Foundation and the National Science Foundation.
