Low resistance, thermally responsive polymeric positive temperature coefficient (PPTC) devices are a practical choice for improving Li chemistry-based cell or pack performance, without sacrificing ...

Automobiles, aircraft, marine vehicles, uninterruptible power supplies, and telecom hardware use series-connected battery stacks. These stacks of individual cells may contain many units, potentially ...

Genetic circuits control the activity of genes and thereby the function of cells and organisms. Scientists have shown how various genetic circuits in bacterial cells are influenced by growth ...

To evaluate the outdoor performance and stability of perovskite solar cells using contactless and noninvasive methods, an Australian and Chinese research team found a way to use photoluminescence ...

Cells in the body are wired like computer chips to direct signals that instruct how they function, research suggests. Unlike a fixed circuit board, however, cells can rapidly rewire their ...

Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell ...

Horizon Fuel Cell Technologies is preparing to introduce what may be the first practical fuel-cell power supply aimed at ordinary consumers. It isn't perfect, but it has the right price point and ...
