Toshiba’s new large-scale production technology for electrolysis electrodes cuts iridium use to 1/10

Green Car Congress

P2G uses electrolysis of water to convert renewable energy into hydrogen, for storage and transportation to where it is needed. Polymer Electrolyte Membrane (PEM) electrolysis is seen as a highly promising conversion method, as it is reacts rapidly to power fluctuations and is highly durable.

Cooper Tire and BRDI consortium partners report significant progress on grant to develop guayule polymer for tires

Green Car Congress

Cooper Tire & Rubber Company, working as the lead agency in the grant, announced that its scientists have reached a key milestone toward the goal of producing, by mid-2017, a concept tire in which all of the natural and synthetic rubber is replaced by guayule-based polymers. The grant period ends in the second quarter of 2017.

Harvard researchers develop tough, self-healing rubber

Green Car Congress

Self-healing materials aren’t new—researchers at SEAS have developed self-healing hydrogels, which rely on water to incorporate reversible bonds that can promote healing. Rubber is made of polymers often connected by permanent, covalent bonds. These two types of bonds are intrinsically immiscible, like oil and water, said Cai.

PEM fuel cell X-ray CT study details effects of temperature and moisture on performance

Green Car Congress

Polymer electrolyte membrane (PEM) fuel cells require precise temperature and moisture controls to be at their best. Specifically, the researchers used synchrotron-based micro X‐ray computed tomography (CT) to visualize and to quantify the water distribution within gas diffusion layers subject to a thermal gradient. —Shum et al.

UBC engineers use fiber from recycled tires to develop more resilient concrete

Green Car Congress

The researchers experimented with different proportions of STF and other materials used in concrete—cement, sand and water—before finding the optimal mix, which includes 0.35% tire fibers, according to researcher Obinna Onuaguluchi, a postdoctoral fellow in civil engineering at UBC. Relative to a plain reference mixture, 0.4%
