How organic solar cells could become significantly more efficient      (via sciencedaily.com)     Original source 

The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.

There is much to improve in identifying all the chemicals around us      (via sciencedaily.com) 

What chemicals are we exposed to on a daily basis? That is the central question of 'non-targeted analysis' or NTA, an emerging field of analytical science that aims to identify all chemicals around us. A daunting task, because how can you be sure to detect everything if you don't know exactly what you're looking for?

Extensive impact of metal mining contamination on rivers and floodplains      (via sciencedaily.com) 

A groundbreaking study has provided new insights into the extensive impact of metal mining contamination on rivers and floodplains across the world, with an estimated 23 million people believed to be affected by potentially dangerous concentrations of toxic waste. The study used a new georeferenced global database of 185,000 metal mines compiled by the team alongside a combination of process-based modelling and empirical testing to predict the dispersal of mine waste in river systems to offer a comprehensive understanding of the environmental and health challenges associated with metal mining activities, examining both historical and active mining operations. With the rapid growth of metal mining crucial to the world making the transition to green energy, the study provides governments, mining companies, environmental regulators, and communities impacted by mining operations with a tool to understand the impacts of environmental impact of mining. Ultimately it is hoped that this will make it easier to mitigate the environmental effects of historical and present mining and help to minimise the impacts of future mining development on communities, while also protecting food and water security.

Making contact: Researchers wire up individual graphene nanoribbons      (via sciencedaily.com) 

Researchers have developed a method of 'wiring up' graphene nanoribbons (GNRs), a class of one-dimensional materials that are of interest in the scaling of microelectronic devices. Using a direct-write scanning tunneling microscopy (STM) based process, the nanometer-scale metal contacts were fabricated on individual GNRs and could control the electronic character of the GNRs. The researchers say that this is the first demonstration of making metal contacts to specific GNRs with certainty and that those contacts induce device functionality needed for transistor function.
