Why are leaves green?

jameszbw

Leaves are green due to the presence of a green coloured pigment called chlorophyll. the main function of chlorophyll is to perform photosynthesis in the presence of sunlight. Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

“Green” electronics represents not only a novel scientific term but also an emerging area of research aimed at identifying compounds of natural origin and establishing economically efficient routes for the production of synthetic materials that have applicability in environmentally safe (biodegradable) and/or biocompatible devices. The ultimate goal of this research is to create paths for the production of human- and environmentally friendly electronics in general and the integration of such electronic circuits with living tissue in particular. Researching into the emerging class of “green” electronics may help fulfill not only the original promise of organic electronics that is to deliver low-cost and energy efficient materials and devices but also achieve unimaginable functionalities for electronics, for example benign integration into life and environment. This Review will highlight recent research advancements in this emerging group of materials and their integration in unconventional organic electronic devices.

Farming Innovation Programme launched to boost the future of farming

  • d remove the need for pesticides in production

UKRI Challenge Director for the TFP challenge, Katrina Hayter, said:

As the UK gets ready to host COP26 in November, it is timely that we can unveil so many great projects in the vital area of agriculture that will help meet our net zero goals.

Working closely with farmers in the innovation process means that pressing challenges are identified. Solving these challenges will result in maximising productivity, reducing emissions, and making our farms more resilient and sustainable.

Further information on Defra’s new funds is available at the Future Farming Blog and at the dedicated UKRI webpage.

Background

From October 2021:

  • Research Starter Projects – To help farmers and growers with bold, ambitious early-stage ideas develop them further and build a collaborative team – for those who haven’t previously received Innovate UK funding
  • Feasibility Projects – To test the feasibility of early-stage solutions and to inform decisions on subsequent larger scale R&D projects
  • Small R&D Partnership Projects – To carry out R&D for innovative solutions that have the potential to substantially improve overall productivity, sustainability and resilience of the sector

From Spring 2022:

  • Large R&D Partnership Projects – Launching early 2022, this will provide funding for larger-scale R&D and demonstration of solutions that have the potential to substantially improve overall productivity, sustainability and resilience of the sector
  • each competition within the R&D Partnership Fund will offer different scales of funding. Project teams will be able to apply for grants towards the total project costs, while providing some of their own match funding.
  • the competitions will be open to applications for 5-6 weeks, with different closing dates for each competition.
  • video recordings of applicant briefing events are available on the competition pages.
  • more information on the new competitions and how to get involved can be found on the UKRI website
  • further information will follow in the coming months on the other funds available in the Programme, including the Farming Futures R&D Fund, and the Projects to Accelerate Adoption Fund
