The Paris climate summit ended last year with landmark national commitments for greenhouse gas reductions, but much of the hard work of reducing emissions will fall on cities to change their residents’ behavior.
Researchers have demonstrated a safe and affordable battery capable of storing energy from intermittent sources — like rooftop solar panels — that is suitable for the home.
Researchers have identified a contributing factor to short lifetime in perovskite solar cells with silver electrodes. Currently, the most common electrode material in perovskite solar cells is gold, which is extremely expensive. The low-cost alternative to gold is silver, around 65 times cheaper.
adminThey sound like futuristic weapons, but electron guns are actually workhorse tools for research and industry: They emit streams of electrons for electron microscopes, semiconductor patterning equipment and particle accelerators, to name a few important uses. Now scientists have figured out how to increase these electron flows 13,000-fold by applying a single layer of diamondoids – tiny, perfect diamond cages – to an electron gun’s sharp gold tip.
Are you sick of your phone’s battery dying after only a few hours? Researchers are hard at work on improving something called the solid electrolyte interphase as a way to boost battery life.
A team of researchers made a decisive step towards a redox-flow battery which is simple to handle, safe and economical at the same time: They developed a system on the basis of organic polymers and a harmless saline solution. The new redox-flow battery can withstand up to 10,000 charging cycles without losing a crucial amount of capacity.
Researchers have developed a novel way to noninvasively measure and map how and where trapped light vibrates within microscale optical resonators. Visualizing the vibration patterns will help scientists to perfect ultrasensitive optical sensors for detecting biomolecules and even single atoms.
