| Precision machining produces tiny, light-guiding cubes for advancing info tech Posted: 28 Jan 2022 11:13 AM PST Drilling with the beam of an electron microscope, scientists have precisely machined tiny electrically conductive cubes that can interact with light and organized them in patterned structures that confine and relay light's electromagnetic signal. This demonstration is a step toward potentially faster computer chips and more perceptive sensors. |
| Artificial muscles made of proteins Posted: 28 Jan 2022 11:12 AM PST A research team has developed a material made of natural proteins that contracts autonomously. |
| Solving a superconducting mystery with more precise computations Posted: 28 Jan 2022 07:07 AM PST A new, more precise method of simulating quantum materials has revealed the basis for superconductivity in copper-based oxides known as cuprates. Researchers, using powerful supercomputers, found that phonons, vibrational energy from crystal structure, contribute to a key feature observed in cuprates, which may indicate their indispensable contribution to superconductivity. If true, the finding may pave the way for tunable superconductivity in materials. |
| Shedding light on polymer solar cells: Illuminating how solvent additives improve efficiency Posted: 28 Jan 2022 07:07 AM PST Researchers imaged nanoscale photocurrents in an all-polymer blend solar cell using photoconductive atomic force microscopy. Trace solvent additives were found to enhance polymer ordering and crystallization without undesirable changes in the scale of phase separation necessary for device performance. The findings explain the basis of the performance enhancement attributed to solvent additives and will accelerate research efforts aimed at establishing all-polymer blend solar cells as a viable environmentally sustainable choice. |
| New atomistic level insight into drug-target residence time Posted: 28 Jan 2022 07:07 AM PST A new study helps to explain what defines how long a drug molecule stays bound to its target. |
| Posted: 28 Jan 2022 07:07 AM PST A new study has determined the post-mortem interval of human skeletal remains using real samples, which has been made possible by the combination of two non-destructive analytical tools: Raman spectroscopy and chemometrics. This opens up new avenues for dating in the field of forensic medicine and anthropology. |
| New blood test combined with image-based prostate cancer screening reduces harms and costs Posted: 28 Jan 2022 07:07 AM PST The combination of a novel blood test and magnetic resonance imaging (MRI) can reduce overdiagnosis of low-risk cancers as well as societal costs in prostate cancer screening, according to a cost-effectiveness study. |
| Cosmic physics mimicked on table-top as graphene enables Schwinger effect Posted: 27 Jan 2022 11:15 AM PST Researchers have succeeded in observing the so-called Schwinger effect, an elusive process that normally occurs only in cosmic events. By applying high currents through specially designed graphene-based devices, the team succeeded in producing particle-antiparticle pairs from a vacuum. |
| New, highly efficient catalyst for propylene production Posted: 27 Jan 2022 08:43 AM PST Researchers have developed an innovative catalyst for the synthesis of propylene, which has potential benefits for the chemical industry and carbon recycling. |
| Tiny materials lead to a big advance in quantum computing Posted: 27 Jan 2022 08:43 AM PST Researchers used the 2D material hexagonal boron nitride to build much smaller capacitors for superconducting qubits, enabling them to shrink the footprint of a qubit by two orders of magnitude without sacrificing performance. |
