The ocean holds billions of tons of lithium, and scientists have just tested a new way of extracting it, with a device that takes in seawater and pumps out freshwater and lithium phosphate – plus more than enough H2 and chlorine to pay the power bill.

While reverse osmosis is a relatively energy-efficient form of seawater desalination, it is nonetheless made less efficient by a problem known as biofouling. A new membrane coating, however, could address biofouling like never before.

Making every micrometer count is a key consideration for designers and engineers working on modern smartphones, and a new nanometer-thick form of graphite that helps keep electronic devices cool could free up some valuable space.

New ultrathin solar cells boast a few advantages over others of their type. They're more efficient, made using more common elements, and can be inkjet-printed onto surfaces, making them light and flexible enough to power wearable electronics.

A highly porous and recyclable mat developed at Saudi Arabia’S King Abdullah University of Science and Technology (KAUST) could mean good things for the environment, with its creators reporting it can adsorb oil with great efficiency.

An international team of scientists has created a new type of solar flow battery that’s efficient and long-lasting. The device is made up of a silicon/perovskite tandem solar cell, paired with a redox flow battery, with organic chemical electrolytes.

Although N95 face masks are quite effective at blocking transmission of the COVID-19-causing SARS-CoV-2 virus, they're also intended to be used only a few times at most. A new removable membrane, however, could make them much more reusable.

Radio waves travel poorly through the water, which makes it difficult for divers or submersibles to wirelessly transmit information to the surface. Scientists are trying to change that, though, by developing an underwater version of Wi-Fi.

The "sea skater" is one of the few insects that lives full-time in a marine environment. Scientists are now taking a closer look at how the animal repels water, with an eye towards the development of more hydrodynamic ship hulls.

Given that solar panels lie in direct sunlight, it goes without saying that they can get pretty hot. Unfortunately, though, they also get less efficient as they heat up. That said, a new gel could help cool them … without using any electricity.

Responsible for millions of dollars in crop losses annually, the red palm weevil is a flying beetle that lays its eggs inside date palm trees. It could soon be possible to detect such infestations earlier than ever, using fiber optic cables.

It's vitally important to monitor the water quality of fish farms, as problems such as pollution can quickly prove disastrous. A small new floating cube was designed with this in mind, as it continuously tracks multiple factors.
