Video: Upgrade your barbecue with ‘squeezable’ glass bottles

By Lisa McDonald / June 29, 2022

Though glass bottles have numerous advantages over plastic bottles, they lack the squeezability factor to easily eject their contents. Two entrepreneurs in the U.K. designed a silicon rubber attachment for glass bottles that gives them the squeezability factor.

Titania photocatalysts: Saving the environment…or not?

By Lisa McDonald / May 31, 2022

Titanium dioxide is widely used as a photocatalyst due to its high catalytic activity, excellent chemical stability, low material cost, and minimal toxicity to humans. However, some researchers raised concerns that using TiO2 photocatalytic paints as a remediation technology to improve air quality may do more harm than good.

Video: From interstate eyesore to inlet ecosystem—recycled concrete used to rehabilitate oyster populations

By Lisa McDonald / March 30, 2022

In contrast to corals, the crucial role that oysters play in global ocean health is often overlooked by the general public. Fortunately, governments, conservation groups, researchers, and oyster growers have started seriously investing in oyster restoration projects along the U.S. Atlantic and Gulf coasts. One project by Virginia-based Lynnhaven River NOW not only helps oysters but puts recycled concrete to good use.

Composite showdown—technological developments could lower carbon fiber composites’ environmental impact

By Lisa McDonald / March 4, 2022

Currently, replacing conventional materials with carbon fiber-reinforced polymers typically increases life cycle energy use due to the energy-intensive fiber production process. A new prospective life cycle assessment suggests certain technological developments could lead to carbon fiber composites with lower environmental impact than glass fiber composites.
