Putting the squeeze on soot

Soot particles form complex chain-like structures called fractal aggregates. Credit: Hafiz Amin Running diesel engines and gas turbines at high pressure to boost power output and efficiency is harmful for the environment. Burning fuel at high pressure can significantly change the soot particles that are produced, William Roberts from the KAUST Clean Combustion Research Center and his team have shown. Studying the factors affecting soot formation should lead to new ways to curb soot emissions, says Hafiz Amin, first author…

FOREWORD from the “Ramblings of A Chemical Engineer” Book

FOREWORD I was inspired to choose chemical engineering when I first saw the chemical formula from my father’s chemistry book. The chemical formula shapes look fascinating and interesting to me. My father was an organic chemistry lecturer in Universiti Teknologi Malaysia (UTM). When I was 14, I read his organic chemistry book and willingly learnt from it by myself. When I was 17, I wanted to have a career associated with chemistry. Back then, my first choice was chemical engineering…

Simulation of the forces induced on cylinders by ocean currents could help in the design of off-shore platforms

Modelling vortices in an ocean current around two cylinders could help marine-offshore engineers design better risers. Credit: A*STAR Institute of High Performance Computing A*STAR researchers have developed a model that can simulate the complicated forces exerted by flowing water on an array of cylinders supporting water-borne structures such as oil rigs. The work demonstrates the usefulness of numerical simulations to investigate complex physical real-world scenarios. When designing an off-shore platform, engineers must be able to predict how it will be…

Team improves structural health monitoring with magnetostrictive transducer

Dr. Sergey Vinogradov, an SwRI staff engineer and expert in sensor systems and nondestructive evaluation technology, holds the improved MsT device. The circular, hard-shell MsT sensor clamps around pipes and other metal and nonmetal structures and is available in a variety of circumferences. It detects material flaws, corrosion and areas at risk of developing breaks, cracks and leaks. Credit: Southwest Research Institute A new, more powerful generation of a patented Southwest Research Institute magnetostrictive sensor withstands extreme temperatures, automatically adjusts…

Pair of studies outline innovations that will improve coordination of traffic patterns and save fuel — ScienceDaily

Imagine a daily commute that’s orderly instead of chaotic. Connected and automated vehicles could provide that relief by adjusting to driving conditions with little to no input from drivers. When the car in front of you speeds up, yours would accelerate, and when the car in front of you screeches to a halt, your car would stop, too. At the University of Delaware, Andreas Malikopoulos uses control theory to develop algorithms that will enable this technology of the future. In…

Integrating innovation and climate with economic growth — ScienceDaily

The Royal Swedish Academy of Sciences has decided to award the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2018 to William D. Nordhaus, Yale University, New Haven, USA “for integrating climate change into long-run macroeconomic analysis” and Paul M. Romer, NYU Stern School of Business, New York, USA “for integrating technological innovations into long-run macroeconomic analysis.” Integrating innovation and climate with economic growth William D. Nordhaus and Paul M. Romer have designed methods for addressing some…

‘Turbidity currents’ are not just currents, but involve movement of the seafloor itself — ScienceDaily

Turbidity currents have historically been described as fast-moving currents that sweep down submarine canyons, carrying sand and mud into the deep sea. But a new paper in Nature Communications shows that, rather than just consisting of sediment-laden seawater flowing over the seafloor, turbidity currents also involve large-scale movements of the seafloor itself. This dramatic discovery, the result of an 18-month-long, multi-institutional study of Monterey Canyon, could help ocean engineers avoid damage to pipelines, communications cables, and other seafloor structures. Geologists…

Supercomputing for better commuting—in pursuit of fuel economy and mobility

Credit: GRIDSMART In a project leveraging computer vision, machine learning, and sensors, Oak Ridge National Laboratory scientists are working with private company GRIDSMART Technologies, Inc. to demonstrate how stop lights can be programmed to improve fuel economy and reduce emissions while facilitating the smooth flow of traffic. GRIDSMART traffic cameras are already being used by communities around the world to replace in-road sensors traditionally used to detect vehicles and…

Eighth-century skeleton found at Torcello — ScienceDaily

On the island of Torcello, at the Ca’ Foscari University of Venice excavation site, some protagonists of the island’s thousand-year history have begun to emerge. A tomb datable to around 700 A.D. has recently been unearthed by the site’s team of scholars, who hail from universities throughout Italy, under the scientific direction of archaeologist Diego Calaon (a Marie Curie Fellow). “The subject is a young adult, whose burial — not far from the area we imagine was used as a…

Liquid metal discovery to make toxic water safe and drinkable — ScienceDaily

UNSW and RMIT researchers have discovered a revolutionary and cheap way to make filters that can turn water contaminated with heavy metals into safe drinking water in a matter of minutes. Recent UNSW SHARP hire Professor Kourosh Kalantar-zadeh and his former colleagues at RMIT showed that nano-filters made of aluminium oxide could be cheaply produced using virtually no energy from a fixed amount of liquid metal gallium. In a paper published in Advanced Functional Materials, lead author Dr Ali Zavabeti…
