- Enhancing electron transfer for highly efficient upconversion OLEDs 22/08/2024 Electron transfer is an elementary process in which an electron is transferred or relocated from a donor molecule or atom to another such entity, called the acceptor. This process is fundamental to chemical reactions, electronic devices, and even living organisms.
- New states of matter unveiled in ‘first time’ quantum flatland discovery 20/08/2024 This development was observed under extreme conditions of near absolute zero temperatures (-459°F or -273°C) and intense magnetic fields nearly 100,000 times stronger than Earth’s.
- Solving the doping problem: Enhancing performance in organic semiconductors 06/08/2024 Cavendish physicists have discovered two new ways to improve organic semiconductors. They found a way to remove more electrons from the material than previously possible and used unexpected properties in an environment known as the non-equilibrium state, boosting its performance for use in electronic devices.
- Raman spectroscopy offers new insights into ionic liquid acidity 01/08/2024 Researchers at the University of Liège have for the first time determined the acidity of ionic liquids using Raman spectroscopy, thanks to Hammett acidity functions. This advance promises to revolutionize our understanding and use of these organic solvents, in which dissolved acids can be remarkably more acidic than in water, with an acidity that can be up to 100 million times greater.
- Artificial neural network syndrome decoding on IBM quantum processors 25/07/2024 Syndrome decoding is an integral but computationally demanding step in the implementation of quantum error correction for fault-tolerant quantum computing. Here, we report the development and benchmarking of Artificial Neural Network (ANN) decoding on IBM quantum processors. We demonstrate that ANNs can efficiently decode syndrome measurement data from heavy-hexagonal code architecture and apply appropriate corrections to facilitate error protection. The current physical error rates of IBM devices are above the code's threshold and restrict the scope of our ANN decoder for logical error rate suppression. However, our work confirms the applicability of ANN decoding methods of syndrome data retrieved from experimental devices and establishes machine learning as a promising pathway for quantum error correction when quantum devices with below threshold error rates become available in the near future.
- New synthesis method enhances MoS₂ optoelectronic performance 23/07/2024 An international research team led by Professor My Ali El Khakani of the Institut national de la recherche scientifique (INRS) has made a surprising discovery about the properties of molybdenum disulfide, also known as MoS2. The material is highly sought after in optoelectronics.
- Scientists discover way to 'grow' sub-nanometer sized transistors 18/07/2024 A research team led by Director Jo Moon-Ho of the Center for Van der Waals Quantum Solids within the Institute for Basic Science (IBS) has implemented a novel method to achieve epitaxial growth of 1D metallic materials with a width of less than 1 nm. The group applied this process to develop a new structure for 2D semiconductor logic circuits. Notably, they used the 1D metals as a gate electrode of the ultra-miniaturized transistor.
- High-selectivity graphene membranes enhance CO₂ capture efficiency 16/07/2024 Reducing carbon dioxide (CO₂) emissions is a crucial step towards mitigating climate change and protecting the environment on Earth. One proposed technology for reducing CO₂ emissions, particularly from power plants and industrial establishments, is carbon capture.
- Researchers explain the imaging mechanisms of atomic force microscopy in 3D 12/07/2024 Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University report the 3D imaging of a suspended nanostructure. The technique used is an extension of atomic force microscopy and is a promising approach for visualizing various 3D biological systems.
- New probe reveals water-ice microstructures 10/07/2024 Ice is believed to have played a crucial role in the emergence of life. One reason is that organic molecules can be excluded into the gaps between the crystal lattice by orderly arranged water molecules, leading to the concentration of organic compounds.
- Redox-fluid ligand stabilised as triradical for the first time 04/07/2024 An exotic triradical aluminium complex is the first of its kind to be isolated and characterised. Containing three ‘redox non-innocent’ dithiolene ligands stabilised in radical form, the new species exists in an unusual quartet ground state and could have implications for the design of superconducting and single-molecule magnetic materials.
