Owing to its mixed ionic and electronic conductivity and high thermochemical stability, La 0.6 Sr 0.4 FeO 3-δ (LSF64) is an attractive electrode material in solid oxide fuel/electrolysis cells (SOFCs/SOECs). Well defined thin film microelectrodes are used to compare the electrochemical properties of LSF64 in oxidizing…
A series of Eu 2+ -doped α-Ca 1.65 Sr 0.35 SiO 4 phosphors synthesized via the high-temperature solid-state reaction method can emit intense green light under UV/n-UV excitation, which show potential application in UV/n-UV-pumped white-light-emitting diodes.
A flexible UV photodetector (PD) has been fabricated based on the amorphous InGaZnO film. It shows good photoresponse characteristics before and after bending, and fast response speed compared with the most reported flexible UV PDs.
A hybrid polymeric electrode PEDOT:PSS/PANI was prepared by ink-jet printing and electropolymerisation, obtaining high capacitance, low resistivity and linear response to pH in a large window.
High-efficiency red phosphors with non-rare-earth activators are emerging as an alternative for next generation solid-state warm white LEDs. Their optical properties depend strongly on the local site symmetry and the crystal field strength. Herein we present the pressure tuning of structural and photoluminescence (PL)…
Directed self-assembly of carbon nanotubes into 2D rhombic nanomesh films results in greatly lower sheet resistance, higher stretchability, and better mechanical durability than those of random carbon nanotube films.
Type 304 stainless steel was subjected to low-temperature carburizing treatment to add excess interstitial carbon to its surface. The average carbon concentration in the carburized layer was ca. 2.6 mass%, and the lattice parameter was expanded by ca. 2.5% without any carbide precipitation. No pitting was initiated on…
We present a route to fabricate a robust anti-icing superhydrophobic surface containing the hierarchical structures of microscale array patterns (built by micromachining) and nanohairs (prepared via hydrothermal growth) on a Ti 6 Al 4 V substrate.
CO 2 hydrogenation towards COOH is more favorable on perfect CeO 2 (111) surface, whereas reductive dissociation of CO 2 is predominant on O-defective surface. The O vacancy promotes reductive dissociation of CO 2 on O-defective CeO 2 (111) surface.
In triplet-triplet annihilation-based photon upconversion (TTA-UC), the utilization of near-infrared (NIR) light with a wavelength longer than 850 nm remains an outstanding issue. We realized this by employing metallonaphthalocyanines as triplet sensitizers; upon excitation of NIR light (856 nm), upconverted emission…
Sol–gel prepared copper chromium delafossite electrodes behave as stable and efficient photocathodes for water reduction without the need for co-catalysts.
Interfacial charge-transfer (ICT) transitions are expected to be a novel charge-separation mechanism for efficient photovoltaic conversion featuring one-step charge separation without energy loss. Photovoltaic conversion due to ICT transitions has been investigated using several TiO2-organic hybrid materials that show…
Core-shell structured Nd(3+)-sensitized NaYF4:Yb/Nd/Er@NaYF4:Nd@mSiO2 nanoparticles (NPs) were designed and synthesized. The NaYF4:Yb/Nd/Er@NaYF4:Nd core imparts the nanomaterials with luminescence properties for upconversion optical imaging under 808 nm laser irradiation, whereas the mesoporous SiO2 shell allows the…
A green, simple, and efficient technology for direct production of cellulose mixed esters with acetyl and long chain acyl substituents.
A novel ferrocene-based nanoporous organic polymer has been prepared by coupling 1,1′-ferrocene-dicarboxaldehyde with melamine.
In this study, well-intergrown NiAl–CO 3 LDH films with excellent anti-corrosive capacity, considerable long-term corrosion durability as well as strong mechanical stability are prepared from CO 2 -saturated precursor solution in one step.
A series of gallium and indium complexes containing a bis(imino)phenolate ligand framework were synthesized and completely characterized with different spectroscopic techniques. The molecular structures of a few complexes were determined using single crystal X-ray diffraction studies. These compounds were found to be…
A facile method for detection of Hg 2+ in living cells based on DNA modified graphene quantum dots.
The phenomenon of ‘self-purification’ is a real mechanism operative in nanocrystals and this should be taken into account while doping semiconductor nanocrystals with external impurities for practical applications.
Nitrogen-doped graphene oxide dots exhibit excitation-wavelength independent photoluminescence at 530 nm and 50% quantum yield. The dots show excellent white light emission by combining green emissions with violet light used for excitation.
