More than 2 billion people, approximately a quarter of the world’s population, lack access to clean drinking ラーメンベット 出金 銀行. A new, portable and affordable ラーメンベット 出金 銀行 filtration solution created by researchers at The University of Texas at Austin aims to change that.

The new system collects dirty ラーメンベット 出金 銀行 with a syringe and injects it into a hydrogel filter that weeds out nearly all tiny particles. This device, the researchers say, offers significant advantages in cost, simplicity, effectiveness and sustainability compared existing commercial options, giving users the ability to easily decontaminate ラーメンベット 出金 銀行 from nearby streams and rivers and make it drinkable.

The reality is, a large percentage of the world’s population lacks access to safe drinking ラーメンベット 出金 銀行, even in places where fresh ラーメンベット 出金 銀行 sources are available.

“The pressing concern of particle-polluted ラーメンベット 出金 銀行, particularly in remote and underdeveloped regions where people frequently rely on contaminated ラーメンベット 出金 銀行 sources for consumption, demands immediate attention and recognition,” said Guihua Yu, a professor of materials science at the ラーメンベット 禁止ゲーム of Engineer’s Walker Department of Mechanical Engineering and Texas Materials Institute. “Our system, with its high efficiency in removing diverse types of particles, offers an attractive yet practical solution in improving freshwater availability.”

The ラーメンベット 出金 銀行 was published recently in Nature Sustainability.

Today’s options for portable ラーメンベット 出金 銀行 filtration of tiny particles mostly consist of filter paper and microporous membranes. According to the research, these devices filter out roughly 40% and 80% of particles larger than 10 nanometers, respectively. This new system catches close to 100% of these particles.

And it is made of low-cost, sustainable, readily available materials. The main innovation is an intertwined web of nanocellulose fibers that catches particles while the newly cleaned ラーメンベット 出金 銀行 passes through.

All the user has to do is take the syringe to the nearest ラーメンベット 出金 銀行 source, pull out the ラーメンベット 出金 銀行 and inject it through the filter. The system takes care of the rest, spitting out clean, drinkable ラーメンベット 出金 銀行.

The filter system has been tested with several types of ラーメンベット 出金 銀行 sources, including muddy ラーメンベット 出金 銀行, river ラーメンベット 出金 銀行 and ラーメンベット 出金 銀行 contaminated with microplastics. The hydrogel films are biodegradable and can be used up to 30 times before they need to be replaced.

The ラーメンベット 出金 銀行 team has tested the technology using syringes as large as 1.5 liters, about 40% of an individual’s daily drinking ラーメンベット 出金 銀行 needs. And they plan to continue developing the technology to use it at larger scales to tackle global drinking ラーメンベット 出金 銀行 needs.

The researchers were motivated by one of the United Nations’ Sustainable Development Goals to improve drinking ラーメンベット 出金 銀行 standards and sanitation worldwide. Meeting this goal, according to the U.N., will require a 6X increase in drinking ラーメンベット 出金 銀行 availability by 2030.

“The reality is, a large percentage of the world’s population lacks access to safe drinking ラーメンベット 出金 銀行, even in places where fresh ラーメンベット 出金 銀行 sources are available,” said Chuxin Lei, lead author and a graduate student working in Yu’s lab, said. “There is an urgent need for simple, universal, and efficient materials and devices for purifying particle-contaminated ラーメンベット 出金 銀行, which should be able to help people around the world obtain clean ラーメンベット 出金 銀行.”

Team members on the project also include collaborators from Northeast Forestry University, Shanghai Tech University and Tsinghua University in China.
