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.

Building a theory of quantum gravity

Posted by in categories: cosmology, mathematics, particle physics, quantum physics

The Isaac Newton Institute for Mathematical Sciences (INI) in Cambridge hosted a research programme on one of the most pressing problems in modern physics: to build a theory that can explain all the fundamental forces and particles of nature in one unifying mathematical framework. Such a theory of quantum gravity would combine two hugely successful frameworks on theoretical physics, which have so far eluded unification: quantum physics and Einstein’s theory of gravity.

The Black holes: bridges between number theory and holographic quantum information programme focusses on black holes, which play a hugely important part in this area, on something called the holographic principle, and on surprising connections to pure mathematics. This collection of articles explores the central concepts involved and gives you a gist of the cutting edge research covered by the INI programme.
