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...

Construction workers at risk of unintentionally exposing families to multiple toxic metals

Engineering
A range of work and home-related factors, such as not having a work locker or a place to launder work clothes, can impact the level of toxic metal concentrations that workers track from their worksites to their home. Take-home exposures -- toxic contaminants that are unintentionally brought from the workplace into the home, exposing children and other family members -- are a documented public health hazard, but the majority of research and interventions have focused on take-home exposure to lead. Much less is known about take-home exposures to other harmful metals. Now, a new study led by a Boston University School of Public Health (BUSPH) researcher provides evidence that construction workers, in particular, are at high risk of inadvertently tracking a host...
