Sentences with phrase «artificial photosynthetic»

«The operating principles of artificial photosynthetic systems are similar to redox flow batteries and fuel cells in that charge - carriers need to be transported to electrodes, reactants need to be fed to catalytic centers, products need to be extracted, and ionic transport both from the electrolyte to catalytic centers and across channels needs to occur,» Ager says.

To address these challenges, the Molecular and Nanoscale Interfaces Project aims to couple light absorbers, catalysts, and half - reactions for optimal control of the rate, yield, and energetics of electron and proton flow at the nanoscale, so that complete macroscale artificial photosynthetic systems can achieve maximum conversion of solar photon energy into the chemical energy of a fuel.

In an artificial photosynthetic system, the oxidation of water molecules into oxygen, electrons and protons (hydrogen ions) provides the electrons needed to produce liquid fuels from carbon dioxide and water.

The innovative aspect of this activity was the notion that the concept of macroscopic devices could be extended to the molecular level, and that it was possible to design supramolecular systems that, upon stimulation with external energy stimuli such as UV / Visible light, are capable of performing a variety of specific functions: (i) systems for information processing (e.g., wires, switches, antennas, plug / socket systems, extension cables, memories, logic gates, encoder / decoder, rudimentary neuron - like systems), (ii) devices that when powered by chemical energy or electrochemical energy or by light exhibit machine - like behavior (e.g., piston / cylinder systems, shuttles, lifts, rotary rings, dendritic photo - switchable boxes), and (iii) components for artificial photosynthetic systems.

The discovery of this artificial photosynthetic system, however, is a victory in the fight against global warming.

The combination of all these components help drive the artificial photosynthetic process.

MacDonnell also has worked on developing new photocatalysts for hydrogen generation, with the goal of creating an artificial photosynthetic system which uses solar energy to split water molecules into hydrogen and oxygen.

Not exact matches

They are designing an artificial system that mimics how plants and other photosynthetic organisms use sunlight to convert CO2 and water into molecules that humans can later use for fuel.

Each component of the artificial leaf serves a specific function in the photosynthetic process:

As both an «electrograph» (meaning it can undergo direct electron transfers from an electrode), and an «acetogen» (meaning it can direct nearly 90 - percent of its photosynthetic products towards acetic acid), M. thermoacetica serves as the ideal model organism for demonstrating the capabilities of this hybrid artificial photosynthesis system.

On the other hand, as we have written frequently, solar energy is perhaps better captured using a technique involving an artificial leaf or photosynthetic stage.
