Spoof surface plasmons (SSPs) play crucial roles in terahertz (THz) near-field photonics. However, both high-efficiency excitation and wavefront engineering of SSPs remain great challenges, which hinder their wide applications in practice. Here, a scheme is proposed to simultaneously achieve these two goals efficientl…
Thermoelectric materials with high average power factor and thermoelectric figure of merit (ZT) has been a sought-after goal. Here, we report new n-type thermoelectric system Cu x PbSe 0.99 Te 0.01 ( x = 0.0025, 0.004, and 0.005) exhibiting record-high average ZT ∼ 1.3 over 400–773 K ever reported for n-type polycryst…
Abstract While 2D MXenes have been widely used in energy storage systems, surface barriers induced by restacking of nanosheets and the limited kinetics resulting from insufficient interlayer spacing are two unresolved issues. Here an Sn 4+ preintercalated Ti 2 CT X with effectively enlarged interlayer spacing is synth…
Abstract A series of glycolated polythiophenes for use in organic electrochemical transistors (OECTs) is designed and synthesized, differing in the distribution of their ethylene glycol chains that are tethered to the conjugated backbone. While side chain redistribution does not have a significant impact on the optoel…
Growing water and land pollution, the possibility of exhaustion of raw materials and resistance of plastics to physical and chemical factors results in increasing importance of synthetic polymers waste recycling, recovery and environmentally friendly ways of disposal. Polyurethanes (PU) are a family of versatile synth…
Microplastic contamination of the\nmarine environment is widespread,\nbut the extent to which the marine food web is contaminated is not\nyet known. The aims of this study were to go beyond visual identification\ntechniques and develop and apply a simple seafood sample cleanup,\nextraction, and quantitative analysis m…
