Figure 1. The floating contact system like the one found in Hirose’s FX26 Series board-to-board connector increases reliability by reducing the stress on solder joints caused by misaligned connectors. The floating design also enhances durability by preventing solder cracking.

The popularity of  hybrid vehicles (HEV) and electric vehicles (EV) continues to rapidly grow. This can be attributed to consumer demand for eco-friendly vehicles combined with increased confidence in the technology. Almost every automotive manufacturer has HEV and/or EV vehicles in future manufacturing pla

Fuel Cells for Hydrogen Vehicles are Becoming Longer Lasting

The new electrocatalyst for hydrogen fuel cells consists of a thin platinum-cobalt alloy network and, unlike the catalysts commonly used today, does not require a carbon carrier.

Fuel cells are gaining in importance as an alternative to battery-operated electromobility in heavy traffic, especially since hydrogen is a CO2-neutral energy carrier if it is obtained from renewable sources. For efficient operation, fuel cells need an electrocatalyst that improves the electrochemical reaction in

Investigating a Thermal Challenge for MOFs

An illustration of metal organic frameworks (MOFS).

To the naked eye, metal organic frameworks (MOFs) look a little like sand. But if you zoom in, you will see that each grain looks and acts more like a sponge--and serves a similar purpose. MOFs are used to absorb and hold gases, which is useful when trying to filter toxic gases out of the air or as a way to st

A Closer Look at Water-Splitting's Solar Fuel Potential

Francesca Toma (right) and Johanna Eichhorn developed a special technique using an atomic force microscope at Berkeley Lab's JCAP laboratory to capture images of thin-film bismuth vanadate at the nanoscale to understand how a material's properties can affect its performance in an artificial photosynthesis device.

In the fight against climate change, scientists have searched for ways to replace fossil fuels with carbon-free alternatives such as hydrogen fuel. A device known as a photoelectrical chemical cell (PEC) has the potential to produce hydrogen fuel through artificial photosynthesis, an emerging renewable energy te
