Technique Offers Advance in Testing Micro-Scale Compressive Strength of Cement
Researchers have, for the first time, used a “micropillar compression” technique to characterize the micro-scale strength of cement, allowing for the development of cement with desirable strength properties for civil engineering applications.
Above the Battlefields of World War I
James Allen Higgs Jr., a Raleigh native and two-time engineering graduate of NC State, had a birds-eye view of the battlefields of France during the First World War.
Water Efficiency in Rural Areas is Getting Worse, Even as it Improves in Urban Centers
A nationwide analysis of water use over the past 30 years finds that there is a disconnect between rural and urban areas, with most urban areas becoming more water efficient and most rural areas becoming less and less efficient over time.
Hands-On Model Helps Students Understand Genetic Engineering
A team of faculty and undergraduate researchers have created an interactive, physical model to teach students about genetics and biological processes at the cellular level.
Advanced Biomass Cookstoves Provide Benefits in Field Settings, But Less than Expected from Lab Testing
Researchers find that while advanced wood-burning cookstoves can provide benefits to the environment, the benefits are less than expected due to higher emissions measured in the field compared to laboratory settings.
New Tech Uses Electricity to Track Water, ID Potential Problems in Concrete
Researchers have developed a new technique for tracking water in concrete structures – allowing engineers to identify potential issues before they become big problems.
‘Sensing Skin’ Detects Cracks, Harmful Chemicals in Structures
Researchers have developed a multi-layered “sensing skin” to detect corrosive or otherwise harmful substances in structures. The skin can also detect cracks and other structural flaws that are invisible to the naked eye.
How Forecasting Water Reclamation Use Can Save Money, Water Resources
A changing climate and recent droughts in the South and West highlight the need to make the most of our limited water resources. One of the tools that can help the U.S. make efficient use of its water supplies is water reclamation – but utilities and water managers have sometimes struggled to deal with public perceptions of reclaimed water.
Toilets, Pit Latrines and Adventures in Human Waste
According to Francis de los Reyes III, the problem with World Toilet Day is that it focuses almost entirely on toilets. And he's working on that.
Automobile Emissions Expert Can Discuss Volkswagen Scandal, Emissions Testing
Reporters interested in understanding how VW cheated, what emissions tests are and how they work, and how these deceptions can be detected can contact vehicle emissions expert Chris Frey.
