Sustainability Summit –

Two new studies demonstrate how to fabricate materials with single atom-sized pores that can be used for liquid and gas filtration. This regime of “zero dimensional” pores has a broad range of future applications, from water and gas purification to energy harvesting.  The first study, published in ACS Nano (“Stochastic Ionic Transport in Single Atomic Zero-Dimensional Pores”) and led by graduate student Jothi Priyanka Thiruraman, postdoc Paul Masih Das, and professor Marija Drndić, shows the ionic transport properties of these pores, with promise for applications in water purification and desalination as well as for creating artificial pores that mimic ion channels in biology.

Actress Kerry Washington has made an investment of undisclosed size in direct-to-consumer jewelry startup Aurate. This isn’t the first time Washington has gotten involved in startups — she’s also backed The Wing, Community and Byte. In fact, when we asked her about her dream investment at Disrupt in September, she hinted at a new deal that “feels pretty dreamy.” When I brought up those comments earlier this week, Washington laughed and confirmed that Aurate is exactly what she’d been thinking about. In addition to providing funding, Washington also collaborated with the company to create The Lioness Collection, which features two of Aurate’s bestselling gold chains bonded together as both a necklace and a bracelet, along with hoop earrings and a pendant inspired by the Egyptian goddess Sekhmet. Washington was excited about Aurate’s goals of sustainability (its gold comes from sustainable sources) and making fine jewelry more affordable. Plus, she said, “I love working with female founders,” to the extent that she and Aurate founders Sophie Kahn and Bouchra Ezzahraoui have become “our own lioness tribe.” “I was inspired by the themes of what the lioness means, how lionesses operate, how the lionesses hunt together and nurture their cubs together,” she added. “There’s no hierarchy among lionesses … They are fierce and ambitious but they also take care of each other.” And while the average price point of Aurate jewelry is $300, pricing for items in the Lioness Collection starts at around $150, with 20% of the proceeds going to women’s activist group Supermajority. Kahn recalled “countless Zoom conversations” with Washington to develop the collection, while Ezzahraoui said that the team has been talking to her for the past three years — it took a while to make sure everyone was “aligned philosophically” and to figure out the right partnership. “Aurate…

Environmental sustainability has become a major global agenda; and as such, it requires practical and urgent action. Rapid urbanisation, industrial growth, and the ever-increasing human population have intensified the use of natural resources. At the same time, these factors have also increased the need to protect the natural environment.  A United Nations report, “The Climate Crisis – A Race We Can Win”, affirms that no part of the earth is untouched by the effect of human activities or pollution. Natural resources are being depleted at an alarming rate and are also being contaminated with toxic chemicals, potentially leaving a future world in which the young generations would live in to be quite endangered. It is little wonder that young people are becoming very vocal about environmental sustainability.
