Microbes screened with a new microfluidic process might be used in power generation or environmental cleanup — ScienceDaily

Living in extreme conditions requires creative adaptations. For certain species of bacteria that exist in oxygen-deprived environments, this means finding a way to breathe that doesn’t involve oxygen. These hardy microbes, which can be found deep within mines, at the bottom of lakes, and even in the human gut, have evolved a unique form of breathing that involves excreting and pumping out electrons. In other words, these microbes can actually produce electricity. Scientists and engineers are exploring ways to harness…

Important Tips to Create A More Sustainable Facility

As a Chemical Engineering Student or Chemical Engineer, I believe that you are very much closely attached with your work place. This is actually your facility, plant etc. This is where you learn and practice Chemical Engineering. It’s quite challenging, if you are not sure how to play the game and what you are dealing with. Sometimes, wrong decision can be very costly. You don’t want bad thing happen to your facility. You definitely want the best for your facility,…

Scientists engineer shortcut for photosynthetic glitch, boost crop growth 40% — ScienceDaily

Plants convert sunlight into energy through photosynthesis; however, most crops on the planet are plagued by a photosynthetic glitch, and to deal with it, evolved an energy-expensive process called photorespiration that drastically suppresses their yield potential. Researchers from the University of Illinois and U.S. Department of Agriculture Agricultural Research Service report in the journal Science that crops engineered with a photorespiratory shortcut are 40 percent more productive in real-world agronomic conditions. “We could feed up to 200 million additional people…

A new study shows what nine different world regions have contributed to climate change since 1900, and what will happen moving forward — ScienceDaily

The science is clear that human activities over the last century have contributed to greenhouse-like warming of the Earth’s surface. Much of the global conversation around climate change fixates on what individual countries or regions are contributing to the problem, and what they will do (or not do) to reverse the tide. But Colorado State University’s A.R. Ravishankara, University Distinguished Professor who holds joint appointments in the departments of chemistry and atmospheric science, says the full picture is longer and…

New material could be the answer to infrastructure woes

Credit: Louisiana State University In the early 1990s, Victor Li, a professor of civil and environmental engineering at the University of Michigan, developed Engineered Cementitious Composites, also known as ductile or bendable concrete. More than 20 years later, researchers at LSU are close to bringing this material to mass adoption, producing a cost-effective ECC that utilizes readily available ingredients. Furthermore, through testing to-date, it has proven far superior to traditional concrete and could greatly improve the transportation infrastructure in this…

Citrate-based biomaterial fuels bone healing with less rejection — ScienceDaily

A material based on a natural product of bones and citrus fruit, called citrate, provides the extra energy that stem cells need to form new bone tissue, according to a team of Penn State bioengineers. Their new understanding of the mechanism that allows citrate to aid in bone regeneration will help the researchers develop slow-release, biodegradable, citrate-releasing scaffolds to act as bone-growth templates to speed up healing in the body. “In our lab, we have been working with citrate for…

Lake Erie algal blooms ‘seeded’ internally by overwintering cells in lake-bottom sediments — ScienceDaily

Western Lake Erie’s annual summer algal blooms are triggered, at least in part, by cyanobacteria cells that survive the winter in lake-bottom sediments, then emerge in the spring to “seed” the next year’s bloom, according to a research team led by University of Michigan scientists. The findings advance scientists’ understanding of the basic biology driving the annual summer blooms, which are both an unsightly nuisance and a potential public health hazard. In addition, the work identifies a mechanism to explain…

New ‘smart’ material with potential biomedical, environmental uses — ScienceDaily

Brown University researchers have shown a way to use graphene oxide (GO) to add some backbone to hydrogel materials made from alginate, a natural material derived from seaweed that’s currently used in a variety of biomedical applications. In a paper published in the journal Carbon, the researchers describe a 3-D printing method for making intricate and durable alginate-GO structures that are far stiffer and more fracture resistant that alginate alone. “One limiting factor in the use of alginate hydrogels is…

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…
