For homeowners, moisture buildup can cause the biggest headaches. Mold grows on drywall and wood-based materials, creeping along walls, floors and ceilings. Building materials begin to erode and rot. As insulation becomes damaged, the home’s energy-efficiency decreases. Even human health suffers, as moisture also leads to air-quality issues.

The key to preventing extensive moisture damage is discovering it early, when it can be easily fixed.

Researchers at the Department of Energy’s Oak Ridge National Laboratory are using microwave radar reflection to nondestructively detect and measure the moisture content of materials within walls without removing drywall or cladding. This also expedites moisture identification and enables mold growth to be treated in the early stages.

Throughout the United States, more than 100 million buildings tap into electrical energy to keep heating, ventilation, air conditioning and refrigeration units functioning. HVAC systems cause most of the peak load demand on the electric grid; one way to alleviate the grid burden is to develop new storage options for heating and cooling.

As a partner in the Department of Energy’s Stor4Build Consortium, Oak Ridge National Laboratory is co-leading research with the National Renewable Energy Laboratory, Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory and the American Council for an Energy-Efficient Economy to develop thermal energy storage as a complement to electrical battery storage. 

Yesterday’s polluting fuel could be transformed into a valuable material for tomorrow’s electric vehicle batteries, thanks to a wide-ranging research project that utilizes expertise spanning the Department of Energy’s Oak Ridge National Laboratory. ORNL researchers created and tested two methods for transforming coal into the scarce mineral graphite, which is used in batteries for electric vehicles and renewable energy storage. 

Early forms of recycling shredded old wool and spun it with new wool to form a fabric. Nearly two centuries later, textile recycling still follows a similar process. But today’s textiles are blends of different materials, from synthetics to natural materials. Additionally, garments are dyed or include hardware such as buttons or rivet closures. When clothing is sent to a textile recycler, the consumer might assume their item will be repurposed, however without knowing what a shirt or pair of socks is made of, the textile recycler is at a loss. This gap is where Brian Iezzi, founder of Fibarcode, sees opportunity.
