Reduced power consumption in semiconductor devices

Stepping stones are placed to help travelers to cross streams. As long as there are stepping stones that connect the both sides of the water, one can easily get across with just a few steps. Using the same principal, a research team at POSTECH has developed technology that cuts the power consumption in semiconductor devices in half by placing stepping stones. A research team led by Professor Junwoo Son and Dr. Minguk Cho (Department of Materials Science and Engineering) at POSTECH has succeeded in maximizing the switching efficiency of oxide semiconductor devices by inserting platinum nanoparticles. The findings from the study were recently published in the international journal Nature Communications. The oxide material with the metal-insulator phase transition, in which the phase of...

The power of compost — making waste a climate champion

A new way of using compost could boost global crop production and deliver huge benefits to the planet, according to a study co-led by The University of Queensland. Professor Susanne Schmidt from UQ's School of Agriculture and Food Sciences said adopting a Precision Compost Strategy (PCS) in large-scale agriculture could improve crop yield, soil health and divert biowaste from landfill where it generates harmful greenhouse gases. "Instead of relying just on mineral fertilisers, PCS involves supplementing the right type of compost with nutrients to match the needs of soils and crops," Professor Schmidt said. "Soils that have become compacted and acidic are then aerated and neutralised. "The result is they can retain more water, facilitate root growth and nourish the organisms that keep soils...
