Atomically Precise Models Improve Fuel Cell Understanding

The initial positions of the atoms in this computer model of a solid-oxide fuel cell were based on observations of the actual atomic configuration using electron microscopy. Simulations using this model revealed a previously unreported reaction (red path) in which an oxygen molecule from the yttria-stabilized zirconia layer (layer of red and light blue balls) moves through the bulk nickel layer (dark blue balls) before forming OH on the nickel surface.

Simulations from researchers in Japan provide new insights into the reactions occurring in solid-oxide fuel cells by using realistic atomic-scale models of the active site at the electrode based on microscope observations as the starting point. This better understanding could give clues on ways to improve performance

Research Shows Black Plastics Could Create Renewable Energy

The process by which plastics are converted to carbon nanotube material.

Research from Swansea University has found how plastics commonly found in food packaging can be recycled to create new materials like wires for electricity - and could help to reduce the amount of plastic waste in the future. While a small proportion of the hundreds of types of plastics can be recycled

Fusion Scientists Develop 'Nano-Scale Sculpture Technique'

Fabrication procedures of "the nano-scale sculpture technique" by using a focused ion beam - electron beam (FIB-SEM) device. The upper series shows the schematic view of the fabrication by Ga ion beam. The images of (1) and (4) in the bottom series are the electron microscope (SEM) image corresponding to image (1) and image (4) in the upper series. The region shown by the yellow rectangle in image (4) is suitable for TEM observation.

A research team of fusion scientists has succeeded in developing "the nano-scale sculpture technique" to fabricate an ultra-thin film by sharpening a tungsten sample with a focused ion beam. This enables the nano-scale observation of a cross-section very near the top surface of the tungsten sample

How to Finance Solar Power

Cover for 'Solar Power Finance without the Jargo'.

To borrow a quote from the famous 2011 publication, Sapiens: A Brief History of Humankind, "3,766,800 exajoules of solar energy arrive on earth each year"--but how much of it are we using? And since Earth receives such a huge dose every year for free almost everywhere, why does it still only

Black (Nano)gold Combat Climate Change

Use of black gold can get us one step closer to combat climate change.

Global warming is a serious threat to the planet and the living beings. One of the main cause of global warming is the increase in the atmospheric CO2 level. The main source of this CO2 is from the burning of fossil fuels in our daily lives (electricity, vehicles, industry and many more). Researchers
