Recently, the group of Prof. Labao Zhang of Nanjing University, together with the group of researcher Haiyong Gan of the National Institute of Metrology, China, have developed a new thermal radiation ...

There is even a growing interest among game hunters (and those searching Loch Ness). While an infrared camera can see at night, that doesn’t necessarily mean you’re allowed to fly in the dark – please ...

People may no longer need sunshine to harvest solar power. Researchers from University of New South Wales (UNSW) have found a way to generate electricity using the Earth's radiant infrared heat, ...

Despite a long history of successful observations, and even imaging of the cosmic beast by the Event Horizon Telescope in 2022, one crucial piece of the puzzle— mid-infrared observations (Mid-IR ...

Beyond the visible spectrum, there is an unseen world of heat radiation. Arty infrared film photographs aside, the practical uses of thermal imaging devices – also known as infrared thermal imagers – ...

The device, made of palladium nanosheets covalently bonded with MoS 2, shows an enhanced optoelectronic response in the infrared thanks to the chemically bonded interface between the two materials ...
