Kenneth Balkus and Harvey Liu note in the new study that nitric oxide (NO) helps increase blood flow and regulates a range of other body functions. Scientists have tried for years to find practical ways to store and deliver NO for use in medicine. However, they have had difficulty finding a suitable material that allows controlled delivery of NO. Recent studies suggested that zeolites could work. These porous materials soak up and store large amounts of gases like NO.
The scientists describe development of a new bandage composed of nitric oxide-absorbing zeolites embedded in a special water-repellant polymer. In experiments with laboratory rats, the bandage slowly released nitric oxide and increased blood flow. "The bandage could be used to wrap a donor organ ensuring intimate contact and direct delivery of nitric oxide," the report states. "Additionally, these interwoven fabrics could also find applications in smart textiles such as NO-releasing socks for diabetic patients, who have been shown to produce less nitric oxide than healthy patients."

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
