Chameleons inspire new Multicolor 3D-Printing Technology

Posted by in categories: 3D printing, chemistry, engineering, sustainability

Inspired by the color-changing ability of chameleons, researchers have developed a sustainable technique to 3D-print multiple, dynamic colors from a single ink.

“By designing new chemistries and printing processes, we can modulate structural color on the fly to produce color gradients not possible before,” said Ying Diao, an associate professor of chemistry and chemical and biomolecular engineering at the University of Illinois Urbana-Champaign and a researcher at the Beckman Institute for Advanced Science and Technology.

The study appears in the journal PNAS.

Synergy palladium single atoms and twinned nanoparticles for efficient CO₂ photoreduction

Posted by in categories: engineering, nanotechnology, particle physics

The challenge of regulating the electronic structures of metal single-atoms (M-SAs) with metal nanoparticles (M-NPs) lies in the synthesis of a definite architecture. Such a structure has strong electronic metal-support interactions and maintains electron transport channels to facilitate carbon dioxide photoreduction (CO2PR).

In a study published in Advanced Powder Materials, a group of researchers from Zhejiang Normal University, Zhejiang A&F University and Dalian University of Technology, revealed the engineering of the of Pd single atoms with twinned Pd nanoparticles assisted by strong electronic interaction of the atomic metal with the support and unveiled the underlying mechanism for expedited CO2PR.

“As one of the most promising CO2PR semiconductors, polymeric graphitic carbon nitride (g-C3N4) featured with sp2 π-conjugated lamellar structures can offer electronegative nitrogen atoms to anchor M-SAs, forming active metal-nitrogen moieties (M–Nx),” explained Lei Li, lead author of the study. “However, stable M–Nx configurations forbid tunability of electronic structures of M-SA sites.”

How Does the Brain Make Decisions? Harvard Scientists Shed New Light

Posted by in category: neuroscience

Researchers have uncovered new insights into the way brain cells, or neurons, interact when making a decision, and how the links between these neurons could reinforce a decision.

The study — conducted in mice and led by neuroscientists at Harvard Medical School — is the first to combine structural, functional, and behavioral analyses to explore how neuron-to-neuron connections support decision-making.
