Crumb rubber from old tires can lower road noise and reduce need for road maintenance

Green Car Congress

Ground tire rubber, when blended with asphalt, produces longer lasting road surfaces, and can lower road noise and the need for road maintenance. Other states that are using asphalt rubber, or are studying its potential, include Texas, Nebraska, South Carolina, New York and New Mexico, according to the agency.

New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

In a paper in Nature Materials , the Penn State team reports a molecular-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5 Kim, Thomas E.

New Honeywell polymer additives for asphalt decrease paving energy costs and pollutant emissions

Green Car Congress

Decreased rutting could help roads last longer and decrease the amount of maintenance required. In addition, asphalt formulated with Honeywell Titan doesn’t require high shear mix equipment, making it easy to handle and use.

Proton OnSite achieves hydrogen gas production at 5,000 psi without a compressor

Green Car Congress

Attaining this level without a compressor brings refueling stations a step closer to forgoing this capital- and maintenance-intensive piece of equipment. PEM electrolyzers work by running a current through a solid polymer electrolyte, which through electrolysis draws a hydrogen ion (proton) from deionized water and through the membrane.
