Published Single drop of ethanol to revolutionize nanosensor manufacture
(via sciencedaily.com) Engineers have developed a breakthrough technique to make the processing of nanosensors cheaper, greener and more effective by using a single drop of ethanol to replace heat processing of nanoparticle networks, allowing a wider range of materials to be used to make these sensors.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight
(via sciencedaily.com) Engineers have developed HADAR, or heat-assisted detection and ranging.
Published Scientists uncover a surprising connection between number theory and evolutionary genetics
(via sciencedaily.com) An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has uncovered an unexpected link between pure mathematics and genetics, that reveals key insights into the structure of neutral mutations and the evolution of organisms.
Published How heat treatment affects a milk alternative made from rice and coconut water
(via sciencedaily.com) Whether they're made from soybeans, almonds, oats, or just sourced straight from the cow, milk products must go through heat treatment to prevent harmful bacterial growth and keep them safe. But understanding how these processes affect new, plant-based milk formulations could make the beverages more pleasant to drink as well. Researchers have discovered how pasteurization and sterilization affects the look and feel of one such drink made from coconut and rice.
Published Way cool: 'freeze ray' technology
(via sciencedaily.com) An unusual discovery is now being developed as an on-demand cooling solution for high-flying military electronics.
Published Fusion model hot off the wall
(via sciencedaily.com) Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model evaluates the surface interactions and electron-proton collisions of hydrogen molecules.
Published Novel thermal sensor could help drive down the heat
(via sciencedaily.com) Excess heat from electronic or mechanical devices is a sign or cause of inefficient performance. In many cases, embedded sensors to monitor the flow of heat could help engineers alter device behavior or designs to improve their efficiency. For the first time, researchers exploit a novel thermoelectric phenomenon to build a thin sensor that can visualize heat flow in real time. The sensor could be built deep inside devices where other kinds of sensors are impractical. It is also quick, cheap and easy to manufacture using well-established methods.
Published Catalyst can control methane emissions in natural gas engines
(via sciencedaily.com) A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the advance in single atom catalysis has the potential to lower exhaust emissions of methane, one of the worst greenhouse gases that traps heat at about 25 times the rate of carbon dioxide. Researchers showed that the single-atom catalyst was able to remove methane from engine exhaust at lower temperatures, less than 350 degrees Celsius (662 degrees Fahrenheit), while maintaining reaction stability at higher temperatures.
Published A non-covalent bonding experience
(via sciencedaily.com) Putting a suite of new materials synthesis and characterization methods to the test, a team of scientists has developed 14 organic-inorganic hybrid materials, seven of which are entirely new.
Published Droplet levitation is a new way to explore airborne viruses and microorganisms
(via sciencedaily.com) Researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface. Further exploring the effects of various external conditions on self-sustained droplet levitation will reveal whether it can be harnessed and adapted for microbiology and biochemistry applications.
Published Small-winged and lighter colored butterflies likely to be at greatest threat from climate change
(via sciencedaily.com) Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.
Published Researcher turns one of the basic rules of construction upside down
(via sciencedaily.com) Original source Structural engineers are familiar with seventeenth-century scientist Robert Hooke's theory that a hanging chain will mirror the shape of an upstanding rigid arch. However, new research now shows that this common-held belief is incorrect because, regardless of the similarities, the hanging chain and the arch are two incompatible mechanical systems.
Published Thermal cloak passively keeps electric vehicles cool in the summer and warm in the winter
(via sciencedaily.com) When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery's lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night. The cloak, made predominantly of silica and aluminum, can do so passively without outside energy input and operates without any modification between hot or cold weather.
Published The ground is deforming, and buildings aren't ready
(via sciencedaily.com) A new study has linked underground climate change to the shifting ground beneath urban areas. The phenomenon is affecting all major urban areas around the globe, causing civil structures and infrastructures to crack.
Published GPT detectors can be biased against non-native English writers
(via sciencedaily.com) Original source Researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs.
Published Board games are boosting math ability in young children
(via sciencedaily.com) Board games based on numbers, like Monopoly, Othello and Chutes and Ladders, make young children better at math, according to a comprehensive review of research published on the topic over the last 23 years.
Published Number cruncher calculates whether whales are acting weirdly
(via sciencedaily.com) Original source We humans can be a scary acquaintance for whales in the wild. This includes marine biologists tagging them with measuring devices to understand them better. These experiences can make whales behave erratically for a while. Such behaviour can affect research quality and highlights an animal ethics dilemma. Now, researchers have figured out how to solve the problems with math.
Published Sweat it out: Novel wearable biosensor for monitoring sweat electrolytes for use in healthcare and sports
(via sciencedaily.com) Wearable sensors are becoming a promising tool in personalized healthcare and exercise monitoring. In a recent study, researchers develop a novel wearable chemical sensor capable of measuring the concentration of chloride ions in sweat. By using a heat-transfer printing technique, the proposed sensor can be applied to the outer surface of common textiles to prevent skin irritation and allergies, and could also be useful in the early detection of heat stroke and dehydration.
