This new material, a member of a broad class of compounds called perovskites, could boost the output power of the electron beam and enable long-range communications or remote sensing for a fraction of the current energy costs.
Researchers have built a novel low-cost, compact on-chip microscope, made with consumer electronic products, capable of simultaneously measuring nanometer-thick changes over a large volume in transparent objects such as glass.
Researchers have demonstrated the ability to manipulate the vibrations of a drum of nanometre scale thickness - realizing the world's smallest and most versatile drum. This work has implications in improving the sensitivity of small detectors of mass - very important in detecting the mass of small molecules like viruses.
A new type of electronic sensor that might be used to quickly detect and classify bacteria for medical diagnostics and food safety has passed a key hurdle by distinguishing between dead and living bacteria cells.
Bioengineers have developed an electrical graphene chip capable of detecting mutations in DNA. Researchers say the technology could one day be used in various medical applications such as blood-based tests for early cancer screening, monitoring disease biomarkers and real-time detection of viral and microbial sequences.
Scientists have demonstrated that destabilising the spontaneous polarisation of a special class of materials known as ferroelectrics gives rise to the phenomenon of negative capacitance that could one day lead to transistors with reduced power consumption.
