New sensor chip advances rapid, cost-effective disease diagnostics (22/06/2023)

Texas A&M AgriLife Research scientists and collaborators at Iowa State University have developed a sensor chip that can detect many disease pathogens with 10 times the sensitivity of currently available methods.

Near-infrared persistent luminescence nanoprobe developed for ultrasensitive image-guided tumor resection (20/06/2023)

Medical imaging technology such as magnetic resonance imaging (MRI), computed tomography (CT) and X-ray cannot provide real-time images during tumor resection surgery, and surgeons usually rely on visual cues, touch and experience to distinguish tumor margins, leading to a high probability of tumor residues.

Researchers make major strides toward an all-purpose biosensor chip (17/06/2023)

Researchers have demonstrated significant improvements for chip-based sensing devices used to detect or analyze substances. The achievements lay the groundwork for highly sensitive portable integrated optofluidic sensing devices that could be used to perform various types of medical tests simultaneously even if they involve completely different types of bioparticles—such as viral particles and DNA—at widely varying concentrations.

Breakthrough in understanding charge transport in organic solar cells (17/06/2023)

Researchers from the Professorship of Optics and Photonics of Condensed Matter, headed by Prof. Dr. Carsten Deibel, of Chemnitz University of Technology and other partner institutions are currently working together on solar cells made of novel organic semiconductors, which can be manufactured using established printing or thermal evaporation methods.

New cooling technology developed for quantum computing circuits (17/06/2023)

Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a degree from absolute zero temperature. These temperatures are today easily accessible in modern refrigerators. However, the intrinsic temperature of devices turns out to be much higher because the materials required to make good qubit circuits are by their nature very poor thermal conductors. This thermalization problem becomes more and more acute as the scale and complexity of circuits grow.

Researchers invent low-temperature synthesis method for high-quality tellurium nanomesh for next-generation electronics (17/06/2023)

A collaborative team led by researchers from City University of Hong Kong (CityU) recently invented an innovative method for synthesizing high-quality, semiconducting nanomesh at a lower temperature and production cost than conventional methods. The findings will help enable the large-scale production of nanomesh for next-generation electronics.

International team reports powerful tool for studying, tuning atomically thin materials (17/06/2023)

Physicists have been riveted by systems composed of materials only one or a few layers of atoms thick. When a few sheets of these two-dimensional materials are stacked together, a geometric pattern called a moiré pattern can be formed. In these so-called moiré systems, new, exotic phenomena can occur, including superconductivity and unconventional magnetism.

Novel approach to fabricating artificial graphene nanoribbons with embedded pentagon carbon (17/06/2023)

Graphene nanoribbons (GNRs) have attracted much attention due to their unique electronic structures with high tunability of physical structures.

Researchers use ultrasound to control orientation of small particles (17/06/2023)

Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape—for example, bacteria from other cells—for years, the ability to control their movement has remained a largely unsolved problem, until now.Using ultrasound technology and a nozzle, Penn State researchers have separated, controlled and ejected different particles based on their shape and various properties. They published their results in the journal Small.

Researchers succeed in arranging nanoscale quantum sensors on desired targets (17/06/2023)

University of Tokyo scientists have achieved the delicate task of arranging quantum sensors at a nanoscale, allowing them to detect extremely small variations in magnetic fields. The high-resolution quantum sensors will have potential uses in quantum materials and electronic device research. For example, the sensors can help develop hard disks that use nano-magnetic materials as storage elements. This is the world's first successful high-resolution magnetic field imaging using a nanoscale arrangement of quantum sensors.
