Chemist Hopes 'Artificial Leaf' Can Power Civilization Using Photosynthesis

Imagine an artificial leaf that mimics photosynthesis, which lets plants harness energy from the sun. But this leaf would have the ability to power your homes and cars with clean energy using only sunlight and water.

 This is not some far-off idea of the future. It's reality, and the subject of a jury-prize-winning film in the GE Focus Forward Film Competition.

 Jared P. Scott and Kelly Nyks' short film, " The Artificial Leaf," showcases chemist Daniel Nocera, the inventor of the artificial leaf, a device that he says can power the world.

 "The truth is stranger than fiction," Kelly Nyks, a partner at PF Pictures, told ABC News. "What I think is so exciting is that Dan has taken this science and applied it in a way that makes bringing it to scale to solve the energy crisis for the planet real and possible."

 Nocera's leaf is simply a silicon wafer coated with catalysts that use sunlight to split water to into hydrogen and oxygen components.

 "Essentially, it mimics photosynthesis," Nocera told ABC News.

What can scientists do to try to alleviate hunger?

Plant scientists are working to develop plants that are drought or stress tolerant, require less fertilizer or water, are more resistant to pathogens, and are more nutritious. Drought stress causes plants to produce less food, and the incidence of drought is increasing. It has been possible to breed drought-tolerant traits into many plants. Fertilizer application enhances yields, but also is very energy demanding and polluting. Learning how plants take up and use nutrients helps farmers use fertilizers more effectively and breeders enhance nutrient utilization. Plants are continually threatened by pathogens and pests. Scientists must meet the challenges of newly emerging pathogens by identifying resistant lines and improving management practices. It is also important that our crop plants resist pathogens after they are harvested so that they stay fresh and safe between the time of harvesting and the time they are used as food. Plants provide us with necessary vitamins and nutrients, but many people only have access to relatively nutrient-poor foods. Scientists are breeding plants that are better sources of vitamin A, iron and many other essential nutrients.

This image released by Taiwan's Hualien Agricultural Improvement Station shows four different colors of rice. The colorful grain is not just pleasant for the eye, but contains additional nutrients as the colors come from natural foods, not dyes, researchers say.

Bangladesh is an agricultural economy.Agriculture supports its major income,employment and vital activities.Agriculturists who are graduates from agricultural universities or faculties play major role in the development of Bangladesh.The national association of agricultural graduates,Krishibid Institution,Bangladesh has organized various activities to review the achievements of the agricultural graduates and strengthen the contributions of the graduates for the development of Bangladesh.All agricultural agencies of Bangladesh are observing this day and taking vow for development Bangladesh.Graduates working in various government and non -government agencies,universities and private sectors are taking part in the festivites of the day.
2.  The agricultural sector of Bangladesh is composed of crops,livestock,fisheries and forestry.Ministries of Agriculture,Livestock,Fisheries and Forestry of the government administration are mainly manned by the agricultural graduates.Besides,many banks,specialised agencies and NGOs hire Agricultural graduates for their programmes.
3.  The website of Krishibid Institution,Bangladesh.It reflects the activities of the agriculturist community of Bangladesh.You are invited to visit the website and see the achievements of the Agriculturists working in various organizations of Bangladesh.

জৈব কৃষি কৃষিবিদ organic agriculture

welcome all contributions relevant for organic farming systems

https://web.facebook.com/organicagriculturebangladesh/

Organic agriculture has grown to a sector with profound impact on the societal and agricultural development. Hence, we want to utilize the upcoming seminar to reveal how organic research has contributed, or may contribute to change the many and serious challenges that we face to protect our environment and to ensure a satisfactory living for all. Concurrently, the needs for improvement in practical farming systems, both to support the farmers and to further develop organic farming in a sustainable direction, must be emphasized.
