Physicists figured out how to speed up the boiling of water and save energy at the same time

A team of physicists at the Massachusetts Institute of Technology has developed a technique that will speed up the boiling of water and reduce energy costs. As noted, the principle consists in a certain surface structure of the heating element.

Physicists figured out how to speed up the boiling of water and save energy at the same time

A conventional electric kettle uses a coil or heating disc. However, when the water is heated, bubbles filled with steam appear at the bottom of the kettle. As the temperature rises, their number increases, and if they are too close to each other, they form a gas layer, which reduces the transfer of heat from the heating element to the liquid.

Evelyn Wong and her team came up with a way to avoid this. The new design of the heating element is designed so that the bubbles become larger, but at the same time they do not merge, so that the formation of a gas layer does not occur.

The new heating element includes a set of 10 micrometer wide recesses. On the heating element there are several of these massively, they are placed at a distance of 2 mm from each other on small elevations. These elevations direct the heated water from the very bottom to the recesses, which creates a flow of liquid and increases the heating efficiency.

This is what the surface of the new heating element looks like

Experiments have shown that the heat transfer coefficient of the new element is almost 4 times higher than that of the conventional one, and the critical heat flux (one of the important indicators of gas formation during heating) is almost 1.5 times higher.

It is noted that this will significantly save energy in a number of processes where boiling is used. That is, it will work in all steam turbines.

AI powered creation and processing Adobe launches web version of Photoshop

Adobe has announced the launch of the web version of Adobe Photoshop, a simplified online version of its proprietary desktop application for photo editing.

The web version of Photoshop has been in beta status for almost two years, and is now available as part of all paid Photoshop plans (from $10 per month).

The online editor launches with the popular Generative Fill and Generative Expand tools, which recently debuted on the desktop version of Photoshop. These features are based on Adobe Firefly’s generative AI model and are available for commercial use. They allow you to add, remove or expand content from any image with text descriptions in over 100 languages, while maintaining the lighting conditions and perspective of the original image.

The web version of Photoshop offers a simplified user interface, including a contextual taskbar, allowing you to invite other users to collaborate on projects.

Adobe has previously noted that it hopes to offer a free version of the service that provides most of Photoshop’s core features. However, Adobe senior vice president of digital media Ashley Still has now told reporters that Adobe currently has “no plans to create a freemium offering.”

Xiaomi 14 Pro will receive SoC Snapdragon 8 Gen 3 and a titanium frame. It is also credited with an AMOLED screen with a diagonal of 6.7 inches and a resolution of 3200 x 1440 pixels, a 5000 mAh battery with 120 W charging.

There is scattered data about the camera: some sources say that the device will have a 200-megapixel sensor as the main one, others attribute to it the same inch Sony IMX989 sensor as the Xiaomi 13 Pro. At the same time, everyone agrees that the remaining two sensors will be 50-megapixel.
