Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies.
Published A chemical mystery solved -- the reaction explaining large carbon sinks
(via sciencedaily.com) Original source A mystery that has puzzled the scientific community for over 50 years has finally been solved. A team has discovered that a certain type of chemical reaction can explain why organic matter found in rivers and lakes is so resistant to degradation.
Published Making diamonds at ambient pressure
(via sciencedaily.com) Original source Researchers have grown diamonds under conditions of 1 atmosphere pressure and at 1025 degrees Celsius using a liquid metal alloy composed of gallium, iron, nickel, and silicon, thus breaking the existing paradigm. The discovery of this new growth method opens many possibilities for further basic science studies and for scaling up the growth of diamonds in new ways.
Published Lead-vacancy centers in diamond as building blocks for large-scale quantum networks
(via sciencedaily.com) Original source A lead-vacancy (PbV) center in diamond has been developed as a quantum emitter for large-scale quantum networks by researchers. This innovative color center exhibits a sharp zero-phonon-line and emits photons with specific frequencies. The PbV color center stands out among other diamond color centers due to its ability to maintain optical properties at relatively high temperatures of 16 K. This makes it well-suited for transferring quantum information in large-scale quantum networks.
