Storing CO2 by turning it into rock

Storing CO2 by turning it into rock
In November, the Paris Climate Agreement goes into effect to reduce global carbon emissions. To achieve the set targets, experts say capturing and storing carbon must be part of the solution. Several projects throughout the world are trying to make that happen. Now, a study on one of those endeavors, reported in the ACS journal Environmental Science & Technology Letters, has found that within two years, carbon dioxide (CO2) injected into basalt transformed into solid rock.

Solar smart window offers privacy and light control

Solar smart window offers privacy and light control
Smart windows get darker to filter out the sun's rays on bright days, and turn clear on cloudy days to let more light in. This feature can help control indoor temperatures and offers some privacy without resorting to aids such as mini-blinds. Now scientists report a new development in this growing niche: solar smart windows that can turn opaque on demand and even power other devices. The study appears in ACS Photonics.

Extracting cobalt and lithium from waste batteries

Extracting cobalt and lithium from waste batteries
Although rechargeable batteries in smartphones, cars and tablets can be charged again and again, they don't last forever. Old batteries often wind up in landfills or incinerators, potentially harming the environment. And valuable materials remain locked inside. Now, a team of researchers is turning to naturally occurring fungi to drive an environmentally friendly recycling process to extract cobalt and lithium from tons of waste batteries.

Edible food packaging film made of milk proteins

Edible food packaging film made of milk proteins
At the grocery store, most foods - meats, breads, cheeses, snacks - come wrapped in plastic packaging. Not only does this create a lot of non-recyclable, non-biodegradable waste, but thin plastic films are not great at preventing spoilage. And some plastics are suspected of leaching potentially harmful compounds into food. To address these issues, scientists are now developing a packaging film made of milk proteins - and it is even edible.

Making nail polish while powering fuel cells

Making nail polish while powering fuel cells
Hydrogen is widely regarded as a promising and clean alternative energy source. The traditional source of H2 for fuel cell use is water, which is split into H2 and O2. But O2 is a low-value product. So, this week in ACS Central Science, researchers report a new approach and a new catalyst that can produce not just hydrogen but also valuable chemicals, including the most common ingredient in nail polish.

Powering the IoT with solar and wind energy

Powering the IoT with solar and wind energy
The IoT could make cities "smarter" by connecting an extensive network of tiny communications devices to make life more efficient. But all these machines will require a lot of energy. Rather than adding to the global reliance on fossil fuels to power the network, researchers say they have a new solution. Their report on a single device that harvests wind and solar energy appears in the journal ACS Nano.

Generating electricity with tomato waste

Generating electricity with tomato waste
A team of scientists is exploring an unusual source of electricity—damaged tomatoes that are unsuitable for sale at the grocery store. Their pilot project involves a biological-based fuel cell that uses tomato waste left over from harvests in Florida. The researchers present their work today at the 251st National Meeting & Exposition of the American Chemical Society (ACS).

Desert cactus purifies contaminated water

Desert cactus purifies contaminated water
Farm-grown fish are an important source of food with significant and worldwide societal and economic benefits, but the fish that come from these recirculating systems can have unpleasant tastes and odors. To clean contaminated water for farmed fish, drinking and other uses, scientists are now turning to an unlikely source—the mucilage or inner "guts" of cacti. The researchers present their work at the 251st National Meeting & Exposition of the American Chemical Society (ACS).

Solar cell is semi-transparent & bendable

Solar cell is semi-transparent & bendable
To address the need for a sustainable energy source for flexible electronics, a semi-transparent, bendable solar cell that is made entirely out of plastic is being developed by scientists. The cell, reported in ACS Applied Materials & Interfaces, is being developed by a team led by Professor Yinhua Zhou of the Huazhong University of Science and Technology.

Light used to drive battery power safely

Light used to drive battery power safely
To move the world toward sustainability, scientists are continuing to explore ways to use the power of sunlight to make fuels and generate electricity. Now scientists have developed a way in which to use light to drive battery power safely. The battery, reported in the Journal of Physical Chemistry C, uses light and titanium nitride for the anode.
