Field effect transistors using ultrathin molybdenum disulfide (MoS(2)) have recently been experimentally demonstrated, which show promising potential for advanced electronics. However, large… Expand
Interaction of Fatty Acid Monolayers with Cobalt Nanoparticles
Stable colloidal suspension of magnetic nanoparticles is challenging owing to both van der Waals forces and magnetic dipolar interactions. Thus, it is essential to coat magnetic nanoparticles with a… Expand
Ultrahigh power factor and thermoelectric performance in hole-doped single-crystal SnSe
Heat conversion gets a power boost Thermoelectric materials convert waste heat into electricity, but often achieve high conversion efficiencies only at high temperatures. Zhao et al. tackle this… Expand
Nanoscale Imaging of Buried Structures via Scanning Near-Field Ultrasound Holography
A nondestructive imaging method, scanning near-field ultrasound holography (SNFUH), has been developed that provides depth information as well as spatial resolution at the 10- to 100-nanometer scale.… Expand
Microcantilever resonance-based DNA detection with nanoparticle probes
Microcantilevers are used to detect DNA strands with a specific sequence using gold nanoparticle modified DNA. The hybridization reactions lead to the attachment of gold nanoparticles. After the… Expand
High performance bulk thermoelectrics via a panoscopic approach
One of the intellectual challenges for next generation thermoelectric materials revolves around the synthesis and fabrication of hierarchically organized microstructures that do not appreciably… Expand
