The effects of highly luminescent alkylamine-capped semiconductor cadmium telluride quantum dots (CdTe QDs) dispersion on the optical, electrical, thermal properties and supramolecular order of a discotic liquid crystal were studied.
The R 2 (MoO 4 ) 3 (R = rare earth elements) molybdates doped with Eu 3+ cations are interesting red-emitting materials for display and solid-state lighting applications. The structure and luminescent properties of the R 2– x Eu x (MoO 4 ) 3 (R = Gd, Sm) solid solutions have been investigated as a function of chemical…
New two-photon absorption dyes ( TPEPT1 and TPEPT2 ) were designed and synthesized. These materials show different 2PA properties and unique AIE effects, in which TPEPT1 with higher brightness was used to perform a cell-imaging proposal.
We demonstrated surface-enhanced Raman spectroscopy using a coffee-ring-type three-dimensional silver nanostructure (Ag3D).
Direct growth of large area, uniform and patternable few-layer molybdenum disulfide is achieved on arbitrary insulating substrates by CVD.
The new UV nonlinear optical crystal NaSr3Be3B3O9F4 with dimensions up to 13 × 14 × 20 mm3 was successfully grown by the top-seeded solution growth method from LiF–NaF–B2O3 flux for the first time. The crystalline morphological faces are mainly (101), while (021) or (32) faces may occur depending on the direction of t…
A fullerene ammonium derivative has been combined with different metalloporphyrin-crown ether receptors to generate very stable supramolecules. The combination of fullerene-porphyrin and ammonium-crown ether interactions leads to a strong chelate effect as evidenced by a high effective molarity (3.16 M). The different…
This work presents a flexible thick-film Bismuth Tellurium/Antimony Tellurium (BiTe/SbTe) thermoelectric generator (TEG) with reduced material resistivity fabricated by screen printing technology. Cold isostatic pressing (CIP) was introduced to lower the resistivity of the printed thermoelectric materials. The Seebeck…
Ultraviolet photodetector based on n-ZnO (individual microwire)/p-GaN film heterojunction exhibits excellent performance (0.45 A W −1 ) even without bias.
Effects of both phase boundaries and poling conditions on the piezoelectric activity of (K,Na)NbO3 (KNN)-based ceramics {e.g., (1 − x) (K0.42Na0.58) (Nb0.96Sb0.04)O3–x(Bi0.5K0.5)0.90Zn0.10ZrO3 [(1 − x)KNNS–xBKZZ]} were studied in detail, and their d33 was promoted by refining the phase compositions and choosing optimu…
Aggregation induced emission dye based cross-linked fluorescent glycopolymer nanoparticles with red emission: their synthesis, characterization and application for cell imaging.
Surface enhanced Raman scattering (SERS) tags are in situ probes that can provide sensitive and selective probes for optical analysis in biological materials. Engineering tags for use in the near infrared (NIR) region is of particular interest since there is an uncongested spectral window for optical analysis due to t…
A method based on the thermodynamic equilibrium reached between the hybridization and denaturation of double-stranded DNA (ds-DNA) is opened up to evaluate the hyperthermia performance of magnetic nanoparticles (MNPs). Two kinds of MNPs with different sizes and magnetic performance are chosen, and their temperature in…
The electronic structure and spectroscopic properties of a series of rhenium(I) terpyridine complexes were investigated using density functional theory (DFT) and time dependent density functional theory (TD-DFT) methods. The influence of different substituent groups on the optical and electronic properties of Re(I) te…
Multifunctional, plasmonically-active nanorods based on gold cores and silver shells (AuNR/Ag), after exposure to tomato plants, were found to be taken up in rather short times, being detected by SERS in both roots and stems, while exhibiting lack of phytotoxicity in the concentrations used during this study. Addition…
Two new polyoxometalate (POM)-based hybrid monomers (Bu4 N)5 (H)[P2 V3 W15 O59 {(OCH2 )3 CNHCO(CH3 )CCH2 }] (2) and (S(CH3 )2 C6 H4 OCOC(CH3 )=CH2 )6 [PV 2Mo10 O40 ] (5) were developed by grafting polymerizable organic units covalently or electrostatically onto Wells-Dawson and Keggin-type clusters and were character…
A zero thermal expansion material in a pure form of NaZn13-type La(Fe,Si)13 was fabricated. Through optimizing the chemical composition, an isotropic zero thermal expansion material is achieved. The obtained materials exhibit a low expansion of |α| < 1.0 × 10(-6) K(-1) (α is the coefficient of linear thermal expansion…
Herein we evaluate the influence of an electric field on the coupling of two delocalized electrons in the mixed-valence polyoxometalate (POM) [GeV14 O40 ](8-) (in short V14 ) by using both a t-J model Hamiltonian and DFT calculations. In absence of an electric field the compound is paramagnetic, because the two electr…
BACKGROUND: The inhibitory effect of chitosan films with clove oil (0-50 g kg(-1) ) was evaluated on a range of ten representative food spoilage and pathogenic bacteria. RESULTS: The most sensitive bacteria to the films was Shewanella putrefaciens and the most resistant was Aeromonas hydrophila (inhibition was apparen…
Temperature-dependent and uniform NiO/Co 3 O 4 composites have been presented, which show high specific capacitances and good cycling performances even at high current densities.
