A team of scientists has developed an artificial 'worm gut' to break down plastics, offering hope for a nature-inspired method to tackle the global plastic pollution problem.
Published A new 'metal swap' method for creating lateral heterostructures of 2D materials



Heterostructures of two-dimensional materials have unique properties. Among them, lateral heterostructures, which can be used to make electronic devices, are challenging to synthesize. To address this, researchers used a new transmetallation technique to fabricate heterostructures with in-plane heterojunctions using Zn3BHT coordination nanosheet. This simple and powerful method enables the fabrication of ultrathin electronic devices for ultralarge-scale integrated circuits, marking a significant step forward for 2D materials research.
Published BESSY II: Molecular orbitals determine stability



Carboxylic acid dianions (fumarate, maleate and succinate) play a role in coordination chemistry and to some extent also in the biochemistry of body cells. A team has now analyzed their electronic structures using RIXS in combination with DFT simulations. The results provide information not only on electronic structures but also on the relative stability of these molecules which can influence an industry's choice of carboxylate dianions, optimizing both the stability and geometry of coordination polymers.
Published Researchers reveal elusive bottleneck holding back global effort to convert carbon dioxide waste into usable products



Think of it as recycling on the nanoscale: a tantalizing electrochemical process that can harvest carbon before it becomes air pollution and restructure it into the components of everyday products. The drive to capture airborne carbon dioxide from industrial waste and make it into fuel and plastics is gaining momentum after a team of researchers uncovered precisely how the process works and where it bogs down.

An international research team has succeeded in controlling the chirality of individual molecules through structural isomerization. The team also succeeded in synthesizing highly reactive diradicals with two unpaired electrons. These achievements were made using a scanning tunneling microscope probe at low temperatures.
Published Chemists decipher reaction process that could improve lithium-sulfur batteries



Lithium-sulfur batteries have exceptional theoretical capacity and performance in combination with an element in abundant supply. But the intricate reaction mechanism, particularly during discharge, has been challenging to solve. Researchers have identified the key pathways to a complex sulfur reduction reaction that leads to energy loss and reduced battery life span. The study's findings establish the whole reaction network for the first time and offer insight into electrocatalyst design for improved batteries.

Researchers pioneer dynamic manipulation and the generation principles of trion at the nanoscale using tip-enhanced cavity-spectroscopy.
Published Direct view of tantalum oxidation that impedes qubit coherence



Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
Published Magnesium protects tantalum, a promising material for making qubits



Scientists have discovered that adding a layer of magnesium improves the properties of tantalum, a superconducting material that shows great promise for building qubits, the basis of quantum computers. The scientists show that a thin layer of magnesium keeps tantalum from oxidizing, improves its purity, and raises the temperature at which it operates as a superconductor. All three may increase tantalum's ability to hold onto quantum information in qubits.
Published Unveiling Oxidation-induced Super-elasticity in Metallic Glass Nanotubes



Oxidation can degrade the properties and functionality of metals. However, a research team recently found that severely oxidized metallic glass nanotubes can attain an ultrahigh recoverable elastic strain, outperforming most conventional super-elastic metals. They also discovered the physical mechanisms underpinning this super-elasticity. Their discovery implies that oxidation in low-dimension metallic glass can result in unique properties for applications in sensors, medical devices and other nanodevices.

Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.

Published Tracking unconventional superconductivity



At low enough temperatures, certain metals lose their electrical resistance and they conduct electricity without loss. This effect of superconductivity is known for more than hundred years and is well understood for so-called conventional superconductors. More recent, however, are unconventional superconductors, for which it is unclear yet how they work.
