The Department of Energy’s Oak Ridge National Laboratory and JuggerBot 3D, an industrial 3D printer equipment manufacturer, have launched their second research and development collaboration through the Manufacturing Demonstration Facility, or MDF, Technical Collaboration Program.

In a paper published in National Science Review, scientists demonstrate quantum key distribution using a room-temperature GaN-based single-photon source directly emitting in the telecom band in a deployed fiber link. Special technics are used to minimize the effect of Polarization Mode Dispersion.

An international group of researchers collected one hundred years’ worth of sounds from around the world to investigate how soundscapes differ between urban and natural environments. They also examined how these soundscapes change throughout the day and throughout the year. The research revealed that soundscape rhythms are less predictable for people living in urban areas than for animals in the wild.

Hybrid Photonic polycrystals with a synthetic hybrid dimension enable versatile control of edge channels and corner modes in multiple frequency bands.

A controlled/“living” click polymerization method developed by researchers at Institute of Science Tokyo and Nagoya University enables precise chain-growth of AB-type monomers—traditionally limited to step-growth processes—by leveraging copper-catalyzed azide–alkyne cycloaddition. The approach achieves well-defined polymers with narrow dispersity and enables the bidirectional synthesis of ABA-type block copolymers, offering a powerful new strategy for constructing functional macromolecular architectures from a wide range of monomers.

A new palladium-loaded amorphous InGaZnO_x (a-IGZO) catalyst achieved over 91% selectivity when converting carbon dioxide to methanol, report researchers from Japan. Unlike traditional catalysts, this system leverages the electronic properties of semiconductors to generate all the species necessary for the conversion reaction. This study demonstrates novel design principles for sustainable catalysis based on electronic structure engineering.
