Biocompatible, biodegradable, and luminescent nano material can be used as an alternative bioimaging agent for early cancer diagnosis, which is crucial to achieve successful treatment. Hydroxyapatite (HAP) nanocyrstals have good biocompatibility biodegradability, excellent host rare earth elements. In this study, based on the energy transfer from Gd3+ Eu3+, luminescence enhanced imaging of Eu/Gd codoping HAP (HAP:Eu/Gd) nanocrystals are obtained via coprecipitation with plate-like shape no...
Abstract Introducing nanostructures into bulk thermoelectric materials is an effective strategy for reducing lattice thermal conductivity ( κ lat ). However, large numbers of hanging bonds emerge on account mismatch usually at the interfaces between and matrix, thereby significantly deteriorating carrier mobility µ H ) seriously limiting performance. Here, utilizing cointroduction Gd‐Cu 2 Te n‐type PbSe as a paradigm, zT could be greatly improved. The conduction band flattening caused by Gd...
Chemical doping of sodium is an indispensable means to optimize thermoelectric properties PbTe materials, while a bottleneck that aliovalent atom leads spontaneous intrinsic defects in the matrix, resulting low dopant solubility. Therefore, it urgent improve efficiency Na for maximizing optimization. Here, amazing new insight intentionally introduced Pb vacancies can promote solubility ternary Pb1-x Nax Te reported. Experimental analysis and theoretical calculations provide insights into...
In this study, we report highly transparent yttria ceramics fabricated by a facile hot‐pressing method with tantalum foil shielding which effectively prevents the ceramic samples from carbon contamination caused graphite mold used during process. The hot‐pressed sample was already without post‐annealing step or hot isostatic pressing. For 2‐mm‐thick specimen doped 1 at.% ZrO 2 , in‐line transmittance reaches 74.4% at 400 nm and 81.1% 1100 nm. shows very fine microstructure an average grain...
Abstract Herein, Li 2 Mg x ZrO 3+ ( = 0–1) +2 wt.% LiF ceramics with a rock salt structure were prepared by the solid‐state reaction method. The phase transition mechanism was systematically investigated X‐ray diffraction, and first‐principles calculations. With gradual increase in MgO content, samples underwent monoclinic‐Li 3 to tetragonal‐Li MgZrO 4 cubic‐phase transition. variations of microwave dielectric properties due analyzed multi‐phase mixtures law. In addition, CO adsorption...
PbS is identified as a potential alternative candidate material for thermoelectric power generation and refrigeration, owing to the resemblance with PbTe in crystal band structures. However, performance has reached bottleneck because of its inferior electronic structure high lattice thermal conductivity. This work focuses on optimizing electron–phonon transport by synergistic effect Ti Cu2S n-type PbS. The first-principles calculation, single Kane model, Debye model reveal physical origin...
