Even in today's digital age, the world still relies on paper and ink, most of which ends up in landfills or recycling centers. To reduce this waste, scientists have now developed a low-cost, ...

Chemists have fabricated novel rewritable paper, one that is based on the color switching property of commercial chemicals called redox dyes. The dye forms the imaging layer of the paper. Printing is ...

A sheet of office paper is easy to take for granted, but it’s a modern marvel. It’s flexible and strong and can take any color of ink, yielding high-resolution printed letters. Yet office paper ...

For decades researchers have been exploring how to store data in glass because of its potential to hold information for a long time -- eons -- without applying power. A special type of glass that ...

Paper often faces a short useful life, with printed products ending up in the trash or recycling bin soon after they’re read. Researchers have worked to reduce this waste by making paper that can be ...

Developing efficient photoreversible color switching systems for constructing rewritable paper is of significant practical interest owing to the potential environmental benefits including forest ...

Protein membrane: Converging laser beams etch an interference pattern, or hologram, onto microbial proteins sealed between two plates of glass. Researchers at the University of Connecticut, Storrs, ...

Figure 2: Thermal printing and erasing of a phosphorescent image on a PET paper coated with a polymer film containing self-assembled Cu[C18]L2pz. Typically, a THF solution (415 mg) of Cu[C18]L2pz (11 ...

First developed in China in about the year A.D. 150, paper has many uses, the most common being for writing and printing upon. Indeed, the development and spread of civilization owes much to paper's ...
