We investigate how cosmic web structures affect galaxy quenching in the IllustrisTNG (TNG100) cosmological simulations by reconstructing within each snapshot using DisPerSE framework. measure comoving distance from with stellar mass $\log(M_{\ast}/\mathrm{M}_{\odot}) \geq 8$ to nearest node ($d_{\mathrm{node}}$) and filament spine ($d_{\mathrm{fil}}$) study dependence of both median specific st...
Lead-free piezoelectric ceramics based on 0.90(Bi 0.5 Na )TiO 3 – 0.04(Bi Li 0.06BaTiO with additives MnCO (0.1 wt%) [BNLBT4-6 + Mn0.1], which have a morphotropic phase boundary composition, were prepared by controlling the quenching rate (QR) and, their high-power and electrical properties examined. The depolarization temperature T d could be increased QR. QR = 15.0 0.05 °C/s was 166 119 °C, r...
A new class of lanthanide-doped upconversion nanoparticles are presented that are without Yb3+ or Nd3+ sensitizers in the host lattice. In erbium-enriched core-shell NaErF4 :Tm (0.5 mol %)@NaYF4 nanoparticles, a high degree of energy migration between Er3+ ions occurs to suppress the effect of concentration quenching upon surface coating. Unlike the conventional Yb3+ -Er3+ system, the Er3+ ion ...
Naphthoimidazolium groups can form unique ionic hydrogen bonds with anions as imidazolium moieties, and in addition, they are fluorescent, so no further elaborative synthesis is needed to introduce a fluorescent group. In this paper, three naphthoimidazolium derivatives were synthesized and studied for the recognition of nucleotides. Compound 1 composed of a single naphthoimidazolium group and ...
