Using Waste to Purify Water

Using waste to purify water may sound counterintuitive. But at TU Wien, this is exactly what has now been achieved: a special nanostructure has been developed to filter a widespread class of harmful dyes from water. Read on to learn more about it.

Innovative Membrane Technology Promises Access to Clean Water

Water scarcity has been referred to as the silent existential crisis of our time. Our planet has very little fresh water — and is running out of it quickly. Yet no one seems to be talking about it — until Active Membranes.

Wastewater Treatment and Remediation

This technology could be incorporated into water treatment systems at various stages including water treatment, effluent polishing, resource reclamation, resource recycling, gray water treatment, etc.

An All-Liquid Iron Flow Battery for Better Energy Storage

Flow batteries can serve as backup generators for the electric grid. Flow batteries are one of the key pillars of a decarbonization strategy to store energy from renewable energy resources. Their advantage is that they can be built at any scale, from the lab-bench scale, as in this PNNL study, to the size of a city block.

Exploring 3D Printing in a Weightless Environment

Recent experiments by a team from the West Virginia University focused on how a weightless microgravity environment affects 3D printing using titania foam, a material with potential applications ranging from UV blocking to water purification. ACS Applied Materials and Interfaces published their findings.

Navajo Pottery-Inspired Ceramic Water Filter

Navajo pottery-inspired water filtration system developed by engineers at The University of Texas at Austin can effectively and cheaply disinfect water.

3D-Printed Graphene Aerogels for Water Treatment

The aerogels safely remove contaminants from water without releasing any problematic chemical residue.
