Evaporation is a phase transition in which molecules at the surface of a liquid acquire sufficient kinetic energy to overcome intermolecular forces and escape into the gas phase, occurring at temperatures below the liquid’s boiling point. It is governed by factors such as temperature, vapor pressure gradients, relative humidity, surface area, and airflow, and is often described quantitatively using mass-transfer models like Fick’s law or bulk aerodynamic formulations. In research, evaporation plays a central role in hydrology, climate and energy balance studies, industrial drying processes, and surface-atmosphere exchange modeling, influencing latent heat fluxes and boundary-layer dynamics.
Urban trees are often seen as natural allies in fighting summer heat waves. But how much they actually help to cool their surroundings depends heavily on how moist the soil is. This is the main finding of a new study led ...

An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee-ring effect." As a droplet ...
Droughts are becoming more severe and widespread across the globe. But it's not just changing rainfall patterns that are to blame. The atmosphere is also getting thirstier.

Hot air holds more moisture. That's why you can blow your hair dry even after a steamy shower. It's also what dumps rain in the tropics and sucks water from desert soils.

Drying droplets have fascinated scientists for decades. From water to coffee to paint, these everyday fluids leave behind intricate patterns as they evaporate. But blood is far more complex—a colloidal suspension packed with ...
As the climate warms, the atmosphere is getting thirstier. Scientists define this atmospheric thirst, or evaporative demand, as the amount of water that could potentially evaporate from Earth's surface in response to weather.
