As President Biden's $2 trillion American Jobs Plan places the nation's infrastructure in the spotlight, new research from the University of Georgia suggests states can save money and extend the life of their bridges by taking a fresh approach to how they prioritize maintenance.
Renter protection policies that have curbed mass evictions during the COVID-19 pandemic have played a key role in preventing the spread of SARS-CoV-2 in U.S. cities, according to a new study published in Nature Communications.
In extreme heat or in the vacuum of space: a novel nanomaterial delivers top performance in extreme situations, as demonstrated by TU Wien (Vienna) with international partners.
Perovskites have so far been used for solar cells, as anode materials or electronic components rather than for their catalytic properties. Now scientists at TU Wien have succeeded in producing a special perovskite that is excellently suited as a catalyst for converting CO2 into other useful substances, such as synthetic fuels. The new perovskite catalyst is very stable and also relatively cheap, so it would be suitable for industrial use.
A team at HZB, together with partners from Ben Gurion University and the Technion, Israel, has now analysed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite electrodes is significantly lower than previously assumed. The study demonstrates ways to assess new photoelectrode materials more realistically.
Researchers from the Singapore-MIT Alliance for Research and Technology developed a synthetic framework known as theory-based residual neural network (TB-ResNet) to improve individual decision-making analysis used in travel behaviour research. The research explains that data-driven and theory-driven models, which are generally used as separate methods that are conflicting, are actually highly complementary and can provide valuable insights into urban transportation planning.
Researchers used platinum and aluminum compounds to create a catalyst which enables certain chemical reactions to occur more efficiently than ever before. The catalyst could significantly reduce energy usage in various industrial and pharmaceutical processes. It also allows for a wider range of sustainable sources to feed the processes, which could reduce the demand for fossil fuels required by them.
Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The results are published in the journal Chemical Communications (ChemComm).
Underground pipelines that transport oil and gas are very important engineering communications worldwide. Some of these underground communications are built and operated in earthquake-prone areas. The research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect.
A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person's risk, they do indicate an infrastructure of protection that persists despite how densely populated a person's district might be.
