Meet the nanomachines that could drive a medical revolution

A group of physicists recently built the smallest engine ever created from just a single atom. Like any other engine it converts heat energy into movement – but it does so on a smaller scale than seen before. The atom is ...

One-third of car fuel consumption is due to friction loss

No less than one third of a car's fuel consumption is spent in overcoming friction, and this friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction by anything ...

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 ...

3-D battery structure shows new twist in battery design

(PhysOrg.com) -- Battery life and driving range are two sticky phrases in discussions about why EVs have yet to hit mainstream use. Drivers still feel skittish about the idea of setting out on longer trips on batteries lasting ...

The hidden danger of heavy metals in catalytic converters

The heart of every car is its engine, where the energy of petroleum combustion is transformed to mechanical energy, which makes the car move. Unfortunately, no internal combustion engines are environmentally friendly. Carbon ...

Promising new catalysts for hydrogen fuel cells

Hydrogen fuel cells hold a lot of promise as sustainable and eco-friendly energy sources to power transportation by land, air and sea. But traditional catalysts used to drive chemical reactions in hydrogen fuel cells are ...

New combustion strategy accelerates hydrogen-engine development

(PhysOrg.com) -- Car manufacturers aspire to create hydrogen-powered vehicles that could one day allow energy-efficient, cost-effective travel that emits no greenhouse gases or other pollutants. To further that effort, scientists ...
