A new research shows graphene can filter common salts from water to make it safe to drink. The new findings could lead to affordable desalination technology.

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.

New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources.

The new findings from a group of scientists at The University of Manchester were published in the journal Nature Nanotechnology. Previously graphene-oxide membranes have shown exciting potential for gas separation and water filtration.

Graphene-oxide membranes developed at the National Graphene Institute have already demonstrated the potential of filtering out small nanoparticles, organic molecules, and even large salts. Until now, however, they couldn’t be used for sieving common salts used in desalination technologies, which require even smaller sieves.

Previous research at The University of Manchester found that if immersed in water, graphene-oxide membranes become slightly swollen and smaller salts flow through the membrane along with water, but larger ions or molecules are blocked.

The Manchester-based group have now further developed these graphene membranes and found a strategy to avoid the swelling of the membrane when exposed to water. The pore size in the membrane can be precisely controlled which can sieve common salts out of salty water and make it safe to drink.

As the effects of climate change continue to reduce modern city’s water supplies, wealthy modern countries are also investing in desalination technologies. Following the severe floods in California major wealthy cities are also looking increasingly to alternative water solutions.

By 2025 the UN expects that 14% of the world’s population will encounter water scarcity. This technology has the potential to revolutionise water filtration across the world, in particular in countries which cannot afford large scale desalination plants.

It is hoped that graphene-oxide membrane systems can be built on smaller scales making this technology accessible to countries which do not have the financial infrastructure to fund large plants without compromising the yield of fresh water produced.

Querido asgardiano / a:

Todos y cada uno de nosotros jugamos un papel importante en el para un gran reto que se basa en crear nuestro universo espacial, clave para nuestro porvenir como especie; un lugar para residir y prosperar mientras aumentamos nuestro conocimiento explorando las galaxias y sobre el conjunto del universo que nos rodea. al margen de nuestro preciado planeta tierra. Potenciar las con firmeza las ciencias, las artes y las culturas claves para nuestro progreso.

Mi candidatura tiene por objetivo consolidar cuanto antes este apasionante desafío. Acercar y dar a conocer al mayor número de personas, explicar con detalle, aclarar todas las preguntas y sobre todo invitarles a sumarse a ser ciudadanos de nuestro reino. Mo strar Asgardia a las diversas administraciones públicas e intituciones privadas e instarles a apoyarnos económicamente y con otras acciones. Realizar varias campañas divulgativas de carácter regional y abiertas a todos los públicos para que nuestro reino sea más visible. Optimizar la gestión de recursos competentes para abordar y tratar los diferentes asuntos del mejor modo. Trabajar estando en contacto permanente y constante con cada miembro asgardiano, atendiendo para dar respuesta y resolviendo cada petición, reinvidicación o sugerencia que sirva para mejorar.

En conclusión Ser un alcalde asgardiano ejemplar cumpliendo TODAS LAS premisas pertinentes y facilitar el desarrollo y Mejora de Nuestra Nación Asgardia honorable.

Con tu implicación y gracias a tu voto lo lograremos.

JUNTOS LO HAREMOS POSIBLE.

Добрый день.

Всех единомышленников из Воронежа, Липецка, Тамбова, Белгорода других близлежащих городов приглашаю к общению и встречам в реальности.

Думаю, что вместе у нас будет возможность сделать что-нибудь интересное и полезное.

As the Asgardia Citizen from India, Kolkata City, I look forward to being The Voice of the present and future citizens of the Asgardia – the Space Nation of Future, from this subcontinent!

I present before Asgardia my Democratic And Participative Leadership abilities, that I have honed through years of professional exposure to challenges in managing people, driving them towards one common goal. A process that requires deciphering every individuals’ diverse motivations, desires, objectives and viewpoints, and aligning them through effective communication and participative leadership to enable them to feel part of the greater cause. An act of balancing unity in diversity!

This experience of mine is what I expect to help me present myself as The Representative of future Asgardians from this country. I look forward to being part of this stellar opportunity to be part of the evolution towards the unitary identity of ‘Asgardian’, organically through facilitation of the acquisition of worthy citizens, getting their voices heard, and driving every new Asgardian towards one United Goal – Asgardia, humanity’s next stellar frontier...!

It is necessary to ensure that all citizens act actively and aggressively for the welfare of the Asgardia country, and I see such a future in me as I think first of all that our citizens should be free from the internal hazards of the Asgardian first and that the crime rates should be 0 in this new life. we must have the idea that it is not a privilege but a new way of thinking that the world people understand how our ideas are for a great human community Every purse on the earth should look at the same and we must establish relations with other world countries that we can get political and economic benefits always in transfere in terms of science and technology, science and technology should not be used for arming, but for the future of lonely and lonely people, there should be a state without asgardia army, Everyone that we are different is much better understood.

If I gain the right to be a representative, I will continue to work hard to show that Asgardian is further developed and that we will know how to change our future as the world's racial.

Hello everyone,

I believe we have no doubt that we're living in one of the most interesting moments on earth.

Now it's time to extend this exciting history to space.

This  year in October, I will be representing Korea at the One Young World Summit in the Hague, Netherlands. One Young World is a global youth platform also known as the "Young Davos Forum", that gathers the brightest young leaders from around the world, empowering them to make lasting connections to create positive change.

It will be an honor to serve my city and my country as a mayor of Asgardia. I strongly believe that the potential impact of the collaboration of two roles as the Major of Korea(Asgardia) and One Young World Ambassador will be profound.

If you're thinking of engaging more actively in space politics, you're in the right place with the right person.

Thank you for reading.

Bringing new ideas from all sources

Have Retention in communities in a “all time high”.

Connect and network with other mayors to keep communication of important issues under control.

Understand your needs and take issues into affect!

Though true peace is impossible to achieve, Asgardia seems like it could be as close as it comes.

This is my first day as a (pending) citizen of Asgardia and I have high hopes that this small nation will grow to immeasurable heights. I love what this country stands for, and I love how its symbol is one of unity.

In the coming months, my goal is to learn more about Asgardia, where it's going, and ways I can contribute.

It's great to be here!

Here we are, one human race under one golden dream to unite humanity upon the forefront of the dawn of this new age. We are but specs of dust in this cosmic soup we have the great priviledge to spectate a fleeting breath of its history, and maybe if we as one people work hard enough we may come to understand but a fraction of this universe and just maybe be able to point our race into the future.
