The increasing complexity of composite materials structured on the nanometer scale requires highly sensitive analytical tools for nanoscale chemical identification, ideally in three dimensions. While infrared near-field microscopy provides high chemical sensitivity and nanoscopic spatial resolution in two dimensions, the quantitative extraction of material properties of three-dimensionally stru...

Metamaterials--artificially structured materials with tailored electromagnetic response--can be designed to have properties difficult or impossible to achieve with traditional materials fabrication methods. Here we present a structured metamaterial, based on conducting split ring resonators (SRRs), which has an effective index of refraction with a constant spatial gradient. We experimentally co...

Batteries with high energy density are packed into compact groups to solve the range anxiety of new-energy vehicles, which brings greater workload and insecurity, risking thermal runaway in harsh conditions. To improve battery performance under ambient temperature discharge rate, a management system (BTMS) based on honeycomb-structured liquid cooling phase change materials (PCM) is innovatively...

The conversion of existing buildings to ZEH and ZEB requires increased thermal insulation, in which the insulation window surfaces is particularly important. This study focused on measuring comparing changes conductivity transparent vacuum panels (TVIP), could be used as simple easy install building windows. These were later compared with results obtained from previous studies conducted by othe...
