Rice University researchers prototype diamond-strength building materials from 3-D printed polymer structures


How can we make stronger building materials? An experiment conducted by Rice University's Brown School of Engineering explores this limit by manipulating materials like plastic, metal, and concrete to match the strength of diamonds.

Through a series of tests, the team at Rice, led by graduate student Seyed Mohammad Sajadi, discovered that 3D-printed polymers based on tubulane structures could be mimicked and scaled to produce an incredibly durable structure that can both withstand intense compression forces and deflect projectiles. This breakthrough opens new doors for creating impact-resistant materials that perhaps were not possible to create previously. 

"Sajadi and his colleagues built computer simulations of various tubulane blocks, printed the designs as macroscale polymers, and subjected them to crushing forces and speeding bullets. The best proved 10 times better at stopping a bullet than a solid ...

Wood Urbanism

Resim
Wood Urbanism: From the Molecular to the Territorial Daniel Ibañez, Jane Hutton, Kiel Moe (Editors) Actar Publishers , November 2019 Hardcover | 8 x 10-1/4 inches | 488 pages | English | ISBN: 978-1945150814 | $54.95 PUBLISHER'S DESCRIPTION : Wood holds unique and timely lessons for urbanization, yet it remains inadequately characterized in architecture, landscape architecture, and urbanism. From under-considered thermal properties to emerging manufacturing possibilities, from changing forestry regimes to larger carbon cycle dynamics, Wood Urbanism explores the unique material and scalar properties of wood, presenting it as a critical material for design today. It brings into conversation scholars and practitioners who focus on wood from a range of perspectives: from the working forest to the mid-rise building to the basic cell. Drawing from the inherent intelligence and depth of multiple disciplines, this book offers a transcalar perspective on the role of wood in cont...

Building a gentrification early warning system with big data

Resim
But what if there were a way to see gentrification long before the coffee shops, condos and Whole Foods appear? What if city planners and neighborhoods had an early warning system that could sniff out the changes just as they begin? [...] neighborhood advocates would have the opportunity to implement policies ranging from reserving affordable housing units to educating residents of their renting rights to helping small businesses negotiate long-term lease extensions. In his NPR piece, astrophysics professor Adam Frank explains how various big data sets, like housing prices, eviction records, census data, or social media usage, can be utilized for "predictive analytics" to detect early onsets of gentrification for specific neighborhoods at an increasingly high resolution — and what significant perils come with it.
