Herein, we report an equivalent circuit model for electrochemical impedance spectroscopic (EIS) investigation of the Na + ion diffusion process in MnO 2 . We combine two constant phase elements (CPEs) active in the desired frequency ranges as the element associated with the diffusion reaction of ions in the solid acti…
Schematic diagram of pore formation mechanism of β-PP during stretching at 25 °C and 90 °C.
N-doped GQDs served as an effective photocatalyst for the photochemical synthesis of silver deposited porous g-C <sub>3</sub> N <sub>4</sub> nanocomposites for electrochemical sensing.
carbon of heptamethine core is fragile when exposed to serum proteins or other amine-rich biomolecules. To solve such a structural limitation, a rigid carbon-carbon bond was installed onto the framework of ether-linked NIR fluorophores through the Suzuki coupling. The robust fluorophores replaced as ZW800-1C and ZW800…
Vertically aligned WO <sub>3</sub> nanosheet films are produced <italic>via</italic> a hydrothermal method. The WO <sub>3</sub> nanosheet films exhibit significant optical modulation, fast switching speed, high coloration efficiency and excellent cycling performance. Outstanding electrocatalysis is also achieved by th…
Enhancement of upconversion luminescence is imperative for the applications of upconversion nanocrystals (UCNs). In this work, we investigated the upconversion luminescence enhancement of NaYF4:Yb/Er by Mo(3+) ion doping. It was found that the upconversion luminescence intensities of the green and red emissions of UCN…
In this tutorial we highlight the optimal working methodology for discovering novel heterogeneous catalysts using modern tools. First, we give a structure to the discovery and optimisation process, explaining its iterative nature. Then, we focus in turn on each step of catalyst synthesis, catalysts testing, integratin…
Borondipyrromethene (Bodipy) dyes with strong solid-state photoluminescence are highly desirable for their applications in OLEDs. In this work, a series of meso-(4-R–C6H4)-substituted Bodipy dyes (R = H for B1; R = (OCH2CH2)nOCH2CH3, n = 0–3 for B2–B5, respectively) were prepared through an acid-catalyzed reaction. Th…
Abstract Hybrid materials represent one of the most growing new material classes at the edge of technological innovations. Unique possibilities to create novel material properties by synergetic combination of inorganic and organic components on the molecular scale makes this materials class interesting for application…
The effect of organic molecules on CaCO3 crystallization, in particular on the formation of the initial amorphous calcium carbonate (ACC) phase, is poorly understood despite this knowledge being crucial for designing biomimetic compounds with specific function, strength and stability. We monitored ACC crystallization…
We use (2)H NMR to study the rotational motion of supercooled water in silica pores of various diameters, specifically, in the MCM-41 materials C10, C12, and C14. Combination of spin-lattice relaxation, line-shape, and stimulated-echo analyses allows us to determine correlation times in very broad time and temperature…
We present a general simulation framework for assessing the performance of nanoscale devices that combines several powerful and widely used open-source codes, and based on minimal but chemically accurate tight-binding Hamiltonians obtained from density-functional theory calculations and using maximally localized Wanni…
The level of nitrogen doping of graphene strongly depends on the type of the starting graphite oxide and temperature used.
Two types of hybrid metallofullerene framework are theoretically designed, and their structural stabilities are examined using the density functional theory (DFT) computation.
Highly transparent ZnGa <sub>2</sub> O <sub>4</sub> glass-ceramic materials, showing red long-lasting luminescence arising from the entire sample volume, are reported.
Highly sensitive and accurate detection of hydrogen peroxide using starch-stabilized silver nanoprisms (AgNPrs) combined with image color analysis is proposed. The H <sub>2</sub> O <sub>2</sub> concentration at 1.57 μM can be recognized by naked-eye observation.
Several first-principles calculations based on density functional theory have been carried out looking at the key issues of a magnesium battery with a V2O5 cathode. This kind of magnesium battery was reported by D. Aurbach's group in 2013. Our theoretical studies provide explanations for the experimental findings such…
Ongoing efforts are being made to develop biochar materials that can enhance phosphate sorption for application as a mitigation method to prevent phosphorus transport. Layered double hydroxides (LDHs) embedded in a biochar matrix by liquid-phase deposition has been shown to have high phosphate adsorption capabilities,…
