Thanks to a new design of thermoelectric device Embedded in the bottle cap, it has a USB charging port. By connecting the charging cable, the battery charging icon on the mobile screen is activated.

The water bottle can provide 20 to 30 minutes of electricity after we pour 300 to 500 milliliters of boiling water. Enough to charge a smartphone and other small appliances.

The thermoelectric devices They are made of materials that can convert a temperature difference into electricity.

Researchers at the China Academy of Launch Vehicle Technology, a Chinese space rocket manufacturer, has developed a type of insulated water bottle equipped with a thermoelectric chip that converts the heat of water into electricity to charge devices.

Emphasizing the safety of the invention, its developers guarantee that it produces low voltage and has no risk of short circuit.

The researchers are now looking to establish cooperation with companies to commercialize the concept. The product is likely to be priced at 150 yuan, about 20 euros.

Using Raman spectroscopy, London chemist Robin Clark and his collaborators performed an analysis of the pigments used for the miniatures that illustrate various examples of the Gutenberg Bible.

Raman spectroscopy

He Raman effect It is due to the incidence of a photon hitting a molecule and the consequent interaction with the electron cloud of its bonds, exciting the molecule to a virtual state.

Thanks to this we know what the colors of the Bible are made of:

• Reds: probably cinnabar (mercury sulfide) or hematite (iron oxide).
• Blues: azurite, lapis lazuli or indigo.
• Oranges: minio or realgar.
• Greens: malachite (basic copper carbonate) or verdigris (basic copper acetate).
• Yellow: basic lead carbonate or a lead stannate.
• Ochres: goethite (a basic iron oxide).
• Black: charcoal.
• Whites: calcite.

As it explains Santiago Alvarez in Of women, men and molecules: "A splendid palette that wonderfully resists the passing of the centuries."

The Gutenberg Bible is an edition of the Vulgate, printed by Johannes Gutenberg in Mainz, Germany, in the 15th century.
