First fully rechargeable carbon dioxide battery with carbon neutrality
Lithium-carbon dioxide batteries are attractive energy storage systems because they have a specific energy density that is more than seven times greater than commonly used lithium-ion batteries. However, until now, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy.
Microgel supports 3D printing of organs from stem cells
Scientists have developed a platform that prints bioink into 3D tissues using a supporting slurry of alginate microgel beads. The technique overcomes limitations of conventional bioprinted scaffolds and holds promise for tissue engineering, regenerative medicine, drug screening and developmental biology.
3D printed tissues and organs without the scaffolding
Engineered tissues and organs have been grown with various degrees of success in labs for many years. Many of them have used a scaffolding approach where cells are seeded onto biodegradable supportive structures that provide the underlying architecture of the organ or tissue desired.
Graphene coating could help prevent lithium battery fires
Lithium batteries are what allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known, but so is their tendency to occasionally catch on fire - an occurrence known to battery researchers as "thermal runaway."
2D materials may enable EVs to get 500 miles on a single charge
Lithium-air batteries, which currently are still in the experimental stages of development, can store 10 times more energy than lithium-ion batteries, and they are much lighter. That said, lithium-air batteries could be even more efficient and provide more charge with the incorporation of advanced catalysts made from two-dimensional materials.
Disordered crystals are promising for future battery technology
Tiny, disordered particles of magnesium chromium oxide may hold the key to new magnesium battery energy storage technology, which could possess increased capacity compared to conventional lithium-ion batteries.
