Southwest Research Institute engineers developed a new certification cycle, the Low-Load Cycle (LLC), to gauge the performance of heavy-duty diesel engine after-treatment systems in low-load conditions. Aftertreatment systems filter exhaust emissions and reduce pollutants escaping into the environment. SwRI’s Low-Load Cycle challenges aftertreatment systems by analyzing them in unfavorable, but common, low-load conditions, such as…

Increasing production of second-generation biofuels – those made from non-food biomass such as switchgrass, biomass sorghum, and corn stover – would lessen our reliance on burning fossil fuels, which contributes to climate change. Several barriers have prevented the efficient conversion of that biomass. Lignin, a complex compound in cell walls, blocks access to plant carbohydrates…

Antarctica’s ice sheet spans close to twice the area of the contiguous United States, and its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid waters of the Southern Ocean. When these ice shelves collapse into the ocean, they expose towering cliffs of ice along Antarctica’s edge.…
