- Printing atom by atom: Lab explores nanoscale 3D printing 17/01/2023 It takes chemist Liaisan Khasanova less than a minute to turn an ordinary silica glass tube into a printing nozzle for a very special 3D printer. The chemist inserts the capillary tube—which is just one millimeter thick—into a blue device, closes the flap and presses a button. After a few seconds there is a loud bang and the nozzle is ready for use.
- Entangling Quantum Sensors Can Triple Accuracy 12/01/2023 “Spooky sensing at a distance” via one combined device
- Physicists create the first two-dimensional ferrimagnetism in graphene 10/01/2023 Scientists from St. Petersburg University together with their foreign colleagues have created the world's first two-dimensional ferromagnetism in graphene. Use of the obtained magnetic state of graphene can become the basis of a new approach to electronics, increasing its energy efficiency and speed when developing devices using alternative technologies without the use of silicon.
- New electrochemical measurement output uses data science to reveal microbial electricity generation mechanisms 05/01/2023 Researchers at Japan's National Institute for Materials Science (NIMS) have developed a device capable of taking hundreds of times more electrochemical measurements than conventional devices. By analyzing the device's large amounts of data, the team has identified molecular mechanisms that enable electrogenic bacteria to efficiently generate electricity even when subjected to a wide range of electrode potentials.
- A new measurement technique for 3D orientation imaging of polymer chains 03/01/2023 In some materials, the molecules line up in a regular, repeating pattern. In others, they all point in random directions. But in many advanced materials used in medicine, computer chip manufacturing and other industries, the molecules arrange themselves in complex patterns that dictate the material's properties.
- Cupric oxide exhibiting both magnetic and dielectric properties at room temperature 22/12/2022 The National Institute for Materials Science (NIMS), the Rutherford Appleton Laboratory in the U.K. and the University of Oxford in the U.K. have experimentally confirmed that a cupric oxide exhibits multiferroic state (i.e., both magnetic and ferroelectric properties) at room temperature under high pressure.
- Superconducting diode without magnetic field in multilayer graphene 20/12/2022 Superconductors are the key to lossless current flow. However, the realization of superconducting diodes has only recently become an important topic of fundamental research. An international research team has now succeeded in reaching a milestone: the demonstration of an extremely strong superconducting diode effect in a single two-dimensional superconductor.
- A nanofiltration membrane with asymmetric selectivity toward enhanced water recovery 15/12/2022 Groundwater contamination by emerging pollutants has drawn great concern in recent years. Emerging contaminants such as perfluoroalkyl substances (PFASs), especially perfluorooctanesulfonate (PFOS), were found to be widespread and persistent in groundwater systems due to their high chemical resistance to environmental degradation processes.
- New quantum dots study uncovers implications for biological imaging 13/12/2022 Researchers report the synthesis of semiconductor 'giant' core-shell quantum dots with record-breaking emissive lifetimes. In addition, the lifetimes can be tuned by making a simple alteration to the material's internal structure.
- New technique to synthesize Pt-single-atom catalysts with ultrahigh mass activity 01/12/2022 Hydrogen is a promising clean energy carrier due to its highest gravimetric energy density and zero carbon dioxide emissions. The noble metal platinum (Pt) is the most effective catalyst for electrochemical water splitting to produce hydrogen. However, the rarity and high cost of Pt severely limit its practical application.
- Asphaltene changed into graphene for composites 29/11/2022 The flash Joule heating process turns asphaltenes, a byproduct of crude oil production, into graphene for use in composite materials.
