Mobile phone powered by urine | Chemistry World

Mobile phone powered by urine | Chemistry World | chemistryscoopsforawhite | Scoop.it

The first mobile phone battery to be directly charged by microbial fuel cells feeding on neat urinehas been reported by scientists in the UK.

Back in 2011 we covered the urine-powered fuels cells being developed by Ioannis Ieropoulos and colleagues at Bristol Robotics Laboratory. They had shown that urine was an excellent fuel for direct electricity generation. As a bonus, the cells can reclaim essential nutrients from the urine, making waterwater treatment easier.

This latest study is the first time a commercially available mobile phone has been powered by urine-powered fuel cells. Cascades of electrically connected fuel cells use bacterial action to convert chemical energy in organic matter in urine into electricity.

The team hope their work will lead to emergency charging devices for remote locations.

Secondary Metabolites from the Chinese Liverwort Cephaloziella kiaeri

Secondary Metabolites from the Chinese Liverwort Cephaloziella kiaeri | chemistryscoopsforawhite | Scoop.it

Sixteen new clerodane diterpenoids, cephaloziellins A–P (1–16), and two known analogues (17 and 18) were isolated from an EtOH extract of the Chinese liverwort Cephaloziella kiaeri. The structures of the new compounds were elucidated from extensive spectroscopic data (IR, UV, HRESIMS, 1D NMR, and 2D NMR), and the structures of 5, 9, and 15 were confirmed by single-crystal X-ray diffraction analyses. The absolute configurations of all new compounds were established by comparing experimental and calculated electronic circular dichroism spectra.

Variation in Contents of Main Active Components and Antioxidant Activity in Leaves of Different Pigeon Pea Cultivars during Growth - Journal of Agricultural and Food Chemistry (ACS Publications)

Variation in Contents of Main Active Components and Antioxidant Activity in Leaves of Different Pigeon Pea Cultivars during Growth - Journal of Agricultural and Food Chemistry (ACS Publications) | chemistryscoopsforawhite | Scoop.it

Pigeon pea is an important and multiuse grain legume crop, and its leaves are a very valuable natural resource. To obtain a high-quality biological resource, it is necessary to choose the excellent cultivar and determine the appropriate harvest time. In this study, the variation in contents of main active components and antioxidant activity in leaves of six pigeon pea cultivars during growth were investigated. The level of each individual active component significantly varied during growth, but with a different pattern, and this variation was different among cultivars. Flavonoid glycosides orientin, vitexin, and apigenin-6,8-di-C-α-l-arabinopyranoside showed two peak values at mid-late and final stages of growth in most cases. Pinostrobin chalcone, longistyline C, and cajaninstilbene acid showed remarkablely higher values at the mid-late stage of growth than at other stages. Pinostrobin had an extremely different variation pattern compared to other active components. Its content was the highest at the earlier stage of growth. Principal component analysis (PCA) revealed that vitexin and apigenin-6,8-di-C-α-l-arabinopyranoside were mainly responsible for distinguishing cultivars analyzed. In a comprehensive consideration, the leaves should preferentially be harvested at the 135th day after sowing when the level of active components and antioxidant activity reached higher values. Cultivars ICP 13092, ICPL 87091, and ICPL 96053 were considered to be excellent cultivars with high antioxidant activity. Our findings can provide valuable information for producing a high-quality pigeon pea resource.

Arctic Ocean 'acidifying rapidly'

Arctic Ocean 'acidifying rapidly' | chemistryscoopsforawhite | Scoop.it

Scientists from Norway's Center for International Climate and Environmental Research monitored widespread changes in ocean chemistry in the region. They say even if CO2 emissions stopped now, it would take tens of thousands of years for Arctic Ocean chemistry to revert to pre-industrial levels. Many creatures, including commercially valuable fish, could be affected. They forecast major changes in the marine ecosystem, but say there is huge uncertainty over what those changes will be.

Wearable Clothes will soon analyze your body chemistry to make you healthier

Wearable Clothes will soon analyze your body chemistry to make you healthier | chemistryscoopsforawhite | Scoop.it

A lot of the focus in wearable computing has been on delivering products that help everyday users monitor some of the more basic activity traits, such as steps taken and heart rate. While these are certainly useful metrics for health monitoring, they do not paint the full picture.

 

Computational biologists instead study the chemical changes that occur in people’s bodies with the help of optical sensors, non-invasive devices that use the red-to-near-infrared spectral region to assess the chemical changes that occur in the user’s blood vessels, among other places.

 

By leveraging this cutting-edge technology and wearable computing, we are equipped to understand the changes that occur in a person’s body at a whole new level. The implications of this change span from improved training of athletes to better management of chronic diseases and healthcare.

 

 Some interesting recent cases in research that show the potential for disruption include:

 

Researchers at the National Technical University of Athens have helped individuals self-manage diabetes by stimulating the function of an artificial pancreas with fully embedded wearable systems. A paper in the Journal of Biomechanics shows promising results for wearables in athletic training. Scientists mapped out the physiology of athletes’ ski-jumps in order to determine the biological constraints of each individual’s approach. By comparing data across 22 different skiiers, the scientists were able to determine that the wearable system was a very promising tool for training that captured information beyond the capacity of a traditional camera.Researchers at Texas A&M University are investigating the use of optical sensors to interact with dermally-implanted microparticle sensors. This technology could enable cost cutting and continuous blood chemistry monitoring.Optical sensors used to monitor both athletic performance and overall health by researchers at the Dublin Institute of Technology. The sophisticated sensors interpret user’s sweat particles in order to deduce what is going on at a biological level. One of the sensors measured pH levels of sweat particles in order to deduce dehydration while athletes were running. This is a huge stride for activity tracking because it represents real time monitoring of athletic performance and biological signals
