Living, Sensing, Learning: Next-Generation Bioinspired Building Materials Wednesday, December 23, 2020 AuthorJenny E. Sabin According to the World Green Building Council (WGBC 2017), building and construction account for 39 percent of annual global carbon emissions. The heating, lighting, and cooling of buildings accounts for 28 percent of this total and the remaining 11 percent comes from what is known as embodied ...
Entering the Solar Era: The Next 50 Years of Energy Generation Wednesday, December 23, 2020 AuthorRebecca Saive It would be absurd today if anyone attempted to launch a product using chlorofluorocarbons (CFCs). Yet less than 50 years ago, the use of CFCs was entrenched in industry standards for numerous products, such as aerosols and refrigerants. With the 1987 Montreal Protocol, 197 countries agreed to ...
Catalysis and the Future of Transportation Fuels Monday, February 15, 2021 AuthorJosé G. Santiesteban and Thomas F. Degnan Jr. Transportation is a large and diverse sector that encompasses road (passenger and freight vehicles), aviation, marine, and rail transport. In 2018 this sector accounted for nearly a quarter of global anthropogenic carbon dioxide emissions,[1] so efforts to decarbonize it are critical to achieving ...
Understanding Uncertainty, Context, and Human Cognition: Necessary Conditions for Safe Autonomy Wednesday, December 23, 2020 AuthorSrikanth Saripalli and James E. Hubbard Jr. Autonomous vehicles are still “baffled” by unpredictable human actions such as wrong-way driving, emergency vehicles, and human-guided traffic diversions. Yet this unpredictability gives people an edge in unknown or dangerous situations. Therefore remote supervision by a human and ...
Space Launch in 50 Years: Abundance at Last? Wednesday, December 23, 2020 AuthorGwynne E. Shotwell and Lars Blackmore Space travel is the next necessary step in human evolution. Ensuring that humans can live on multiple planets and be out among the stars, exploring the universe, is both key to human survival and a magnificent source of inspiration. But current single-use rockets make getting to orbit ...
Predicted Advances in the Design of New Materials Tuesday, December 22, 2020 AuthorSusan B. Sinnott and Zi-Kui Liu The prehistory and protohistory of humanity are divided into three ages in terms of materials: the Stone Age (~3.4 million years, until 8700–2000 BC), based on raw materials from nature; the Bronze Age (3500–300 BC), based on human-made copper (alloyed with 12 wt% tin); and the Iron Age ...
The Role of Engineering and Technology in Agriculture Monday, March 8, 2021 AuthorMichael A. Steinwand and Pamela C. Ronald By 2050, the global population is predicted to reach 9.7 billion. If consumption practices do not change and food continues to be wasted at alarming rates, farmers around the world will need to increase production 25–100 percent to meet the associated increase in food demand (Hunter et al. ...
