3D-printed decal electronics for the Internet-of-Everything

butterfly_decalResearchers have created a new method to print high-performance electronics by combining the extremely mature CMOS fabrication processes and recently developed additive manufacturing techniques. For the first time, an affordable and reliable manufacturing process for the integration and packaging of fully flexible high-performance electronics has been developed for future Internet-of-Everything (IoE) applications. Such decal...

Energy generation from heat with a solar cell built backwards

solar_cellSolar cells absorb incoming sunlight and convert a part of photon energy into electricity. The remainder of photon energy is dissipated as heat. Although the idea is rather counter-intuitive, 'reverse solar cell' systems can also generate electric power by emitting rather than absorbing photons. Such systems - known as thermoradiative cells - generate voltage and electric power via non-equilibrium thermal radiation of infrared...

A multifunctional biophotonic platform enabled by moire metasurfaces

microbubbleResearchers demonstrate for the first time a multifunctional biophotonic platform enabled by the multiband resonance peaks of the plasmonic moire metasurfaces. Benefiting from the multiband nature of moire metasurface and the near-field enhancement from the metal-insulator-metal configuration, the scientists achieved a dual-band metasurface patch with strong plasmonic resonances at both near-infrared and mid-infrared regimes.The...

Enhanced kinetics on conductive polar electrocatalysts for lithium-sulfur batteries

electrocatalysisResearchers have explored the role of intrinsic bulk electrical conductivity and surface polarity in the electrocatalysis of polysulfide redox reactions. They synthesized highly porous and conductive titanium carbide (TiC)-based composite cathode materials and to assemble lithium-sulfur (Li-S) batteries with high sulfur loading. Li-S cells employing the as-synthesized TiC-based cathode exhibited reduced internal resistance,...

Insights into the microwave non-thermal effect for tumor therapy

cancer_therapyMicrowave hyperthermia is one of the most important clinical thermotherapy techniques due to the instinctive advantages of non-intrusive heating model, fair depth of penetration in tissues and ideal potential of killing tumor cells without surgical risks or toxicity of chemotherapy. Scientists have now developed a novel multifunctional nanoplatform to combine the non-thermal and thermal effects of microwave to achieve enhanced...

3D printing highly conductive nanocomposites

printed_nanoscaffoldsCarbon nanotube enabled nanocomposites have received much attention as a highly attractive alternative to conventional composite materials due to their mechanical, electrical, thermal, barrier and chemical properties such as electrical conductivity, increased tensile strength, improved heat deflection temperature, or flame retardancy. In new work, researchers report the fabrication of highly conductive carbon nanotube/polylactic...

Nanotube chip captures and analyzes circulating tumor cells in blood

bloodtest_arrayResearchers demonstrate a completely new micro-array design that is looking at capture and detection of circulating tumor cells (CTCs) from an entirely new perspective. As an alternative to invasive biopsies, capturing CTCs is of great interest for evaluating cancer dissemination, predicting patient prognosis, and also for the evaluation of therapeutic treatments, representing a reliable potential alternative to invasive biopsies...

New study shows that iron oxide nanoparticles inhibit tumour growth

cancer_cellsThe intravenous iron-replacement product ferumoxytol and other iron oxide nanoparticles are being used for treating iron deficiency, as contrast agents for magnetic resonance imaging, and as drug carriers. In a new study, researchers have shown an intrinsic therapeutic effect of ferumoxytol on the growth of early mammary cancers and lung cancer metastases in liver and lungs. They showed that ferumoxytol can activate the immune...
