Machinists have a lot of neat shop tricks, but one especially interesting one is shrink-fitting tools. Shrink-fitting achieves an interference fit between tool and holder by creating a temperature difference between the two before assembly. Once everything returns to temperature, the two parts may as well be welded together.

Researchers from Purdue University have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the ambient temperature. Painted on a building, the new paint could help cut cooling costs and … Continue reading Super-white paint reflects 95.5 percent of sunlight to cool buildings
Windows are great for letting in light, but in summer months that comes with an unwanted side order of heat, causing many people to run the air conditioning non-stop. Now, researchers have developed windows that can change color automatically when heat… Continue reading Smart windows darken and become solar cells when heated
Making every micrometer count is a key consideration for designers and engineers working on modern smartphones, and a new material could free up some valuable space. Scientists have developed a nanometer-thick form of graphite that helps keep electroni… Continue reading Ultra-thin graphite films soak up heat to keep smartphones cool
Just like a tennis player might don a white shirt instead of a black one on warm summer’s day, researchers see great potential in dressing buildings in reflective white paints to keep them cool. A team of material scientists is reporting a major advanc… Continue reading Super white paint leans on Teflon to reflect up to 98% of the Sun’s heat
While almost everyone has a heater of some sort in their home, it’s fairly unlikely that the heat provided by a central heating system such as a furnace is distributed in an efficient way. There’s little reason to heat bedrooms during the day, or a kitchen during the night, but …read more
People living in the hottest places on Earth could be up to three times as likely to die from a heart-related cause, according to a newly-published study. Global warming due to climate change has the potential to further worsen the heat-stress problem,… Continue reading Risk of heart-related death may triple in extreme heat environments
It’s safe to say that a warming world is going to lead to greater discomfort for many of its inhabitants, but a new study out of Rutgers University is delving into the details of what this could look like come the end of the century. The team looked at… Continue reading Heat stress may impact over a billion by end of century, study finds
It is well known that dogs boast an incredible sense of smell, but new research has uncovered another way our for-legged friends use their famous noses to find their way around. Scientists have discovered what they describe as an “entirely new sense” i… Continue reading Study finds dogs’ noses can detect heat like an infrared sensor
While we’ve already seen materials that allow people or objects to hide from heat-detecting cameras, they’re typically only effective at one ambient temperature. An experimental new material, however, can be user-adjusted to work over a wide range.Cont… Continue reading Heat-camo material can be adjusted to match ambient temperature
