Quantum speed limit may put brakes on quantum computers

Over the past five decades, standard computer processors have gotten increasingly faster. In recent years, however, the limits to that technology have become clear: Chip components can only get so small, and be packed only ...

Fuel aerosols reducing pollution of the environment

A resource-efficient technology for the production of fuel aerosols has been developed at Tomsk Polytechnic University. The development can be used to quickly ignite the boilers of thermal power plants and boiler houses, ...

Why don't electric cars look like the future?

Electric cars were supposed to be the future – or at least look like it. So now they're here, why do they still look like ordinary petrol and diesel cars and not dazzling props from a science fiction film.

Evaporation dynamics at the nano- and micro-scale

A new evaporation dynamics study finds that very small droplets evaporate more slowly than predicted by current models. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw, ...

World mayors pledge emissions-free cities by 2030

The mayors of London, Los Angeles, Paris and several other major world cities are pledging to ban gasoline and diesel vehicles from "large parts" of their cities by 2030.

Cool flames for better engines

A "cool flame" may sound contradictory, but it's an important element of diesel combustion—one that, once properly understood, could enable better engine designs with higher efficiency and fewer emissions.

Creating longer-lasting fuel cells

Fuel cells could someday generate electricity for nearly any device that's battery-powered, including automobiles, laptops and cellphones. Typically using hydrogen as fuel and air as an oxidant, fuel cells are cleaner than ...

With fossil fuel bans, e-cars shift into higher gear

Beijing's announcement that it is considering joining France and Britain in banning petrol and diesel cars from its smog-clogged roads promises to accelerate a push towards electric vehicles—a race in which Chinese carmakers ...
