Published Unique field study shows how climate change affects fire-impacted forests
(via sciencedaily.com) Original source During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published Two-dimensional nanomaterial sets record for expert-defying, counter-intuitive expansion
(via sciencedaily.com) Original source Engineers have developed a record-setting nanomaterial which when stretched in one direction, expands perpendicular to the applied force.
Published Researchers shine light on rapid changes in Arctic and boreal ecosystems
(via sciencedaily.com) Original source Arctic and boreal latitudes are warming faster than any other region on Earth.
Published 'Nanostitches' enable lighter and tougher composite materials
(via sciencedaily.com) Original source In an approach they call 'nanostitching,' engineers used carbon nanotubes to prevent cracking in multilayered composites. The advance could lead to next-generation airplanes and spacecraft.
Published Trash to treasure -- researchers turn metal waste into catalyst for hydrogen
(via sciencedaily.com) Original source Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com) Original source By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Fires pose growing worldwide threat to wildland-urban interface
(via sciencedaily.com) Original source Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.
Published Cooler transformers could help electric grid
(via sciencedaily.com) Original source Simulations on the Stampede2 supercomputer of the Texas Advanced Computing Center (TACC) are helping scientists engineer solutions to overheating of grid transformers -- a critical component of the electric grid.
Published Researchers advance pigment chemistry with moon-inspired reddish magentas
(via sciencedaily.com) Original source A researcher who made color history in 2009 with a vivid blue pigment has developed durable, reddish magentas inspired by lunar mineralogy and ancient Egyptian chemistry.
Published A single atom layer of gold: Researchers create goldene
(via sciencedaily.com) Original source For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals.
Published New colorful plastic films for versatile sensors and electronic displays
(via sciencedaily.com) Original source Researchers have synthesized triarylborane (TAB) compounds that exhibit unusual optical responses upon binding to certain anions. They also synthesized thin polymer films that incorporate the TAB and retain the sensing as well as the light emission properties of the TAB. This work is an important advance in plastic research and has applications in analyte sensing as well as electronic display technologies.
Published Researchers study effects of solvation and ion valency on metallopolymers
(via sciencedaily.com) Original source Researchers analyzed the effects of solvation and ion valency on metallopolymers, with implications for critical materials recovery and recycling, and environmental remediation.
Published A new spin on organic shampoo makes it sudsier, longer lasting
(via sciencedaily.com) Original source While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.
Published Nanoscale movies shed light on one barrier to a clean energy future
(via sciencedaily.com) Original source New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.
Published Nothing is everything: How hidden emptiness can define the usefulness of filtration materials
(via sciencedaily.com) Original source Voids, or empty spaces, exist within matter at all scales, from the astronomical to the microscopic. In a new study, researchers used high-powered microscopy and mathematical theory to unveil nanoscale voids in three dimensions. This advancement is poised to improve the performance of many materials used in the home and in the chemical, energy and medical industries -- particularly in the area of filtration.
Published New 3D-printing method makes printing objects more affordable and eco-friendly
(via sciencedaily.com) Original source A team of scientists has unveiled a method for 3D printing that allows manufacturers to create custom-made objects more economically and sustainably.
Published New strategy for assessing the applicability of reactions
(via sciencedaily.com) Original source Chemists show that a machine-based method prevents widespread 'bias' in chemical publications.
Published Scientists unveil cutting-edge ruthenium catalyst for new reaction discovery and optimization
(via sciencedaily.com) Original source Researchers have achieved a groundbreaking advancement in catalyst technology.
Published How scientists are accelerating chemistry discoveries with automation
(via sciencedaily.com) Original source Scientists have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new automated approach could analyze chemical reactions in real time and identify new chemical-reaction products much faster than current laboratory methods.
Published A simple, inexpensive way to make carbon atoms bind together
(via sciencedaily.com) Original source The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs.
