A standard laser generated proton beam is created through firing a laser pulse at a thin metallic foil. The new method involves instead first splitting the laser into two less intense pulses, before firing both at the foil from two different angles simultaneously. When the two pulses collide on the foil, the resultant electromagnetic fields heat the foil extremely efficiently. The technique results in higher energy protons whilst using the same initial laser energy as the standard method. CREDIT Yen Strandqvist/Chalmers University of Technology

New method invented to double the energy of proton beam

Proton acceleration is really a secondary effect of laser bombardment. Initially, the laser expels out electrons from the thin solid target. Moving close to...

Removing toxic mercury from contaminated water

Mercury can seep into water supplies from improperly discarded devices containing it, as runoff from landfills & farmland, dumped by factories, or from natural...
The energy system MOST works in a circular manner. First, the liquid captures energy from sunlight, in a solar thermal collector on the roof of a building. Then it is stored at room temperature, leading to minimal energy losses. When the energy is needed, it can be drawn through the catalyst so that the liquid heats up. It is envisioned that this warmth can then be utilised in, for example, domestic heating systems, after which the liquid can be sent back up to the roof to collect more energy -- all completely free of emissions, and without damaging the molecules.
