CarH is a vitamin B12-dependent photoreceptor protein that binds to operator DNA in a tetrameric complex to inhibit gene expression. The tetramer is stable in dark conditions, while exposure to light
One of the main bottlenecks of proton exchange membrane fuel cells (PEMFC) technology is the inefficient catalyst for cathodic oxygen reduction reaction, limiting their efficiency. Pt-alloyed catalyst
When submitted to a very large number of mechanical cycles (~ 1e9 cycles) at very low load levels, structural components generally fail because of the apparition of internal fatigue cracks. Experiment
