Black phosphorus composites with engineered interfaces for high-rate high-capacity lithium storage
We report use of black phosphorus (BP) as the active anode for high-rate, high-capacity Li storage. The formation of covalent bonds with graphitic carbon restrains edge reconstruction in layered BP particles to ensure open edges for fast Li+ entry; the coating of the covalently bonded BP-graphite particles with electrolyte-swollen polyaniline yields a stable solid–electrolyte interphase and inhibits the continuous growth of poorly conducting Li fluorides and carbonates to ensure efficient Li+ transport. The resultant composite anode demonstrates an excellent combination of capacity, rate, and cycling endurance. (Source: ScienceNOW)

Phosphorus deficit may disrupt regional food supply chains
(Stockholm University) Phosphorus-based fertilizer is essential in modern agriculture. In regions with high population growth, more phosphorus will be needed to produce more food. A new study shows that world regions with high population growth rates are also the regions with the highest phosphorus deficit. It also quantifies the environmental impact of a business-as-usual scenario in the phosphorus supply chain to 2050 and identifies alarming rates of pollution and greenhouse gas emissions associated with the phosphorus supply.

Global warming threatens soil phosphorus, says a soil scientist from RUDN University
(RUDN University) A soil scientist from RUDN University found out that the resources of organic phosphorus in the soils of the Tibetan Plateau could be depleted because of global warming. To do so, he compared phosphorus content in the soils from the Tibetan Plateau that has a cold climate and from the warmer Loess Plateau. (Source: EurekAlert! - Biology)

Efficacy of silver diamine fluoride and sodium fluoride in inhibiting enamel erosion: an ex vivo study with primary teeth
ConclusionConsidering phosphorus loss values, 10% SDF seems to be effective in inhibiting enamel erosion after 1% and 10% citric acid challenges, whereas 2% NaF only after 1% citric acid challenge. Regarding calcium loss values, both fluoride agents seem to have no impact on inhibiting enamel erosion after 1% and 10% citric acid challenges. (Source: Dental Technology Blog)

Fostering a sustainable use of phosphorus
(CMCC Foundation - Euro-Mediterranean Center on Climate Change) Phosphorus is critical to food security, ecosystem functioning and human activities. Urbanization and dietary changes, and in particular industrial use of P for chemical fertilizer production, have determined a declining trend especially in the last decades. A study recently published on Nature food realized with the contribution of the CMCC Foundation provides some suggestions on how to address this critical issue while protecting food security.

A plants diet, surviving in a variable nutrient environment
As primary producers, plants rely on a large aboveground surface area to collect carbon dioxide and sunlight and a large underground surface area to collect the water and mineral nutrients needed to support their growth and development. Accessibility of the essential nutrients nitrogen (N) and phosphorus (P) in the soil is affected by many factors that create a variable spatiotemporal landscape of their availability both at the local and global scale. Plants optimize uptake of the N and P available through modifications to their growth and development and engagement with microorganisms that facilitate their capture. The se...
