It might be a good idea to look for inspiration in nature when designing load-bearing foundations for buildings. Researchers from Aarhus University and University of California Davis have delved into pile foundations and found, that piles with snake inspired surface patterns give 25-50 per cent less resistance during installation compared with the pressure they can subsequently support. The findings have been published in Acta Geotechnica.
Researchers at C-Crete Technologies and Rice University have found the right ingredients for cement that does double duty as a structural material and a photocatalytic water purifier with a built-in means of replenishment: simply sand down the material's surface to refresh the photocatalytic quality.
A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay area, Izmit Bay in Turkey and the Gulf of Al-Aqaba in Egypt.
Scientists are warning that drinking water supplies in parts of rural West Africa are being contaminated by lead-containing materials used in small community water systems such as boreholes with handpumps and public taps.
The Korea Institute of Civil Engineering and Building Technology (KICT) has announced the development of an effective structural monitoring technique to monitor massive infrastructures, such as long-span bridge. The method provides accurate and precise responses over whole structural system densely by fusing advantages of multi-fidelity data.
Researchers found that a silica surface such as sand has little effect on slowing down the movement of the plastics, but that natural organic matter resulting from decomposition of plant and animal remains can either temporarily or permanently trap the nanoscale plastic particles, depending on the type of plastics. The work could lead to the development of better ways to filter out and clean up pervasive plastics from the environment.
Various studies show that people of color are disproportionately exposed to air pollution in the United States. However, it was unclear whether this unequal exposure is due mainly to a few types of emission sources or whether the causes are more systemic. A new study that models peoples' exposure to air pollution - resolved by race-ethnicity and income level - shows that exposure disparities among people of color and white people are driven by nearly all, rather than only a few, emission source types.
A joint research study by the Pacific Water Research Centre at Simon Fraser University and the Fraser Basin Council points to the use of certified, nature-based solutions for protecting salmon and aquatic habitats in the Lower Mainland.
Days after the 4 August 2020 massive explosion at the port of Beirut in Lebanon, researchers were on the ground mapping the impacts of the explosion in the port and surrounding city. The goal was to document and preserve data on structural and façade damage before rebuilding.
Researchers at the University of California, Irvine have analyzed CALFIRE wildfire statistics from 2000 to 2019, comparing them with data from 1920 to 1999, to learn that the annual burn season has lengthened in the past two decades and that the yearly peak has shifted from August to July. A new study on the subject was published today in Nature Scientific Reports.
