They are also developing methods that convert solar energy and water directly to hydrogen by harnessing and mimicking biological processes likephotosynthesis. There are several ways to use hydrogen for energy once it is produced. The most prominent is in fuel cells, which convert the chemical energy...

Think of "what is methylation in the body" – and the opposite action, demethylation – as the mechanism that allows the gears to turn and turns biological switches on and off for a host of systems in the body. How does methylation happen? CH3 is provided to the body through a universal...
Meeting the growing demand for sustainable fuels will require significant growth in feedstocks beyond oils and sugars, including renewable fuels from nonbiological origins. The regulation of feedstocks is likely to play a critical role in the evolution of sustainable-fuel demand....
Chemical / biological conversion technologies refer to biochemical processes such as fermentation and transesterification to produce methane, ethanol, biodiesel, hydrogen, etc., as fuel for engines, generators, and fuel cells. For example, landfills, waste and industrial or livestock waste water are ...

The aim of many of these projects is to produce liquid and gaseous fuels with similar energy-carrying properties to conventional fossil fuels. Biofuels Much current work is focused on the production of fuels from biological materials. That isn’t a new idea: Oil, gas and coal all started ...
Complete biomimicking, a quest that has motivated many of scientific communities to attempt to unravel strange aspects of biological water oxidation reaction (WOR). Achieving this utopia allows designing nature-resemble artificial leaves for the final production of oxygen with yields comparable to nature...
