Headline: Chromo-encryption method encodes secrets with color

■ Release Date: 2023.2.13

■ Published by: Ecole Polytechnique Fédérale de Lausanne

■ Keywords: silver, nanostructures, nanophotonics

■ Abstract:

In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.

Headline: 'Magic' solvent creates stronger thin films

■ Release Date: 2023.2.14

■ Published by: Cornell University

■ Keywords: solvent, polymer, coatings

■ Abstract:

A new all-dry polymerization technique uses reactive vapors to create thin films with enhanced properties, such as mechanical strength, kinetics and morphology.

Headline: How a record-breaking copper catalyst converts CO2 into liquid fuels

■ Release Date: 2023.2.16

■ Published by: DOE/Lawrence Berkeley National Laboratory

■ Keywords: copper, catalyst, fuel

■ Abstract:

Researchers have made real-time movies of copper nanoparticles as they evolve to convert carbon dioxide and water into renewable fuels and chemicals. Their new insights could help advance the next generation of solar fuels.

Headline: TFT strategy to enhance flexible display panel performance

■ Release Date: 2023.2.16

■ Published by: Pohang University of Science & Technology (POSTECH)

■ Keywords: transistors, semiconductor, acetylacetonate

■ Abstract:

A research team demonstrates the fabrication of an organic-inorganic hybrid dielectric layer for high-performance solution-processed oxide transistors.

Headline: From plastic waste to valuable nanomaterials

■ Release Date: 2023.2.16

■ Published by: Rice University

■ Keywords: plastic, waste, namomaterials

■ Abstract:

Scientists create carbon nanotubes and other hybrid nanomaterials out of plastic waste using an energy-efficient, low-cost, low-emissions process that could also be profitable.

Headline: Physicists solve durability issue in next-generation solar cells

■ Release Date: 2023.2.16

■ Published by: University of Toledo

■ Keywords: perovskites, solar, cell

■ Abstract:

Physicists jumped a major hurdle standing in the way of the commercialization of solar cells created with halide perovskites as a lower-cost, higher-efficiency replacement for silicon when generating electricity from the sun.

Headline: Perovskites, a 'dirt cheap' alternative to silicon, just got a lot more efficient

■ Release Date: 2023.2.16

■ Published by: University of Rochester

■ Keywords: perovskites, silicon, semiconductor

■ Abstract:

Researchers typically synthesize perovskites in a wet lab, and then apply the material as a film on a glass substrate and explore various applications. A team has instead proposes a novel, physics-based approach, using a substrate of either a layer of metal or alternating layers of metal and dielectric material -- rather than glass.

Headline: Smooth sailing for electrons in graphene

■ Release Date: 2023.2.17

■ Published by: University of Wisconsin-Madison

■ Keywords: graphene, electron, low-resistance materials

■ Abstract:

Physicists have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results have applications in developing new, low-resistance materials, where electrical transport would be more efficient.
