We characterize the electron doping evolution of $({\mathrm{Sr}}_{1\ensuremath{-}x}{\mathrm{La}}_{x}{)}_{3}{\mathrm{Ir}}_{2}{\mathrm{O}}_{7}$ by means of angle-resolved photoemission. Concomitant with the metal insulator transition around $x\ensuremath{\approx}0.05$ we find the emergence of coherent quasiparticle stat…
A series of photoactive rare earth coordination polymer materials RE/Ad/BPDC (Ad = adeninate, BPDC = biphenyl-4,4′-dicarboxylate) with tunable multi-color luminescence are synthesized. Y 0.99 Eu 0.01 /Ad/BPDC has a selective fluorescence quenching effect for Fe 3+ and Cr 2 O 7 2− .
Organic semiconductor distributed feedback (DFB) lasers are of interest as external or chip-integrated excitation sources in the visible spectral range for miniaturized Raman-on-chip biomolecular detection systems. However, the inherently limited excitation power of such lasers as well as oftentimes low analyte concen…
This paper describes a new method for quantitative analysis of dynamic penetration into granular media. The method is based on refractive index matching used to produce transparent synthetic soils. First, a procedure referred to as the embedded plane technique is introduced, to overcome limitations with laser illumina…
Due to the development of novel manufacturing technologies and the increasing availability of nano‐/micromaterials, plasmonics has become an emerging field in photonics research. Although the fabrication of metallic elements has already been widely demonstrated, the development of 3D plasmonic materials is progressing…
Ultra-high-performance concrete (UHPC) incorporates a relatively large volume fraction of very dense cementitious binder with microscale fibers. The dense binder in UHPC can effectively interact with nano- and microscale reinforcement, which offers the promise to overcome the brittleness of UHPC. Nanoscale reinforceme…
Thermal stability has been the important issue in organic solar cell, especially for the large scale fabrication and application in the future. In this work, a new strategy involving the introduction of porphyrin compound (BL) is proposed to prevent the [6,6]‐phenyl C61 butyric acid methyl ester (PC61BM) aggregation.…
We study the spectral effect of the fluctuations of the vibration frequency. Such fluctuations play a major role in nanomechanical and other mesoscopic vibrational systems. We find that, for periodically driven systems, the interplay of the driving and frequency fluctuations results in specific spectral features. We p…
Fe 2 O 3 /Al 2 O 3 is found to be a suitable oxygen carrier candidate for the chemical looping combustion with ultralow methane concentration in a previous study by our team. In order to facilitate the fundamental reactor design and understand the energy consumption, the reduction kinetics mechanism of Fe 2 O 3 (hemat…
The motion and interaction of a bubble pair in a non-Newtonian fluid are numerically simulated by a volume of fluid method. The effects of initial horizontal bubble interval, oblique alignment and fluid rheological properties on the pair of rising bubbles are evaluated.
Abstract Core‐shell structured barium titanate‐poly(glycidyl methacrylate) (BaTiO3‐PGMA) nanocomposites were prepared by surface‐initiated atom transfer radical polymerization of GMA from the surface of BaTiO3 nanoparticles. Fourier transform infrared spectroscopy confirmed the grafting of the PGMA shell on the surfac…
This work demonstrates a simple route to develop mechanically flexible electrodes for Li-ion batteries (LIBs) that are usable as lightweight effective conducting networks for both cathodes and anodes. Removing electrochemically dead elements, such as binders, conducting agents and metallic current collectors, from the…
In biotechnology, SAMs and NC hydrogels of functional nanomaterials are of high interest as 2D and 3D cell culture systems, respectively, to mimic natural ECM and to control cell behaviors. Advanced biotechnological approaches often use nanoscale topography together with suitable surface functionalization, as a model…
A multi-constituent kinetic model is developed that can describe competitive transport and retention of nanoparticles and stabilizing co-polymer.
Membrane-active peptides can be classified as cell-penetrating peptides and antimicrobial peptides (AMPs) that are known to play interchangeable roles. In this study, this dual behaviour was studied for the marine AMP, tachyplesin. It is a well-established cyclic peptide known to possess antimicrobial properties and w…
We present in this study the physical properties of two deep eutectic solvent (DES) mixtures based on solid sulfonium bis[(trifluoromethyl)sulfonyl]imide (S 111 TFSI) aprotic ionic liquid and two different H-bond donors, formamide (FMD) and trifluoroamide (TFA), according to temperature. First, we investigated their t…
ABSTRACT Naphthalimide‐phthalimide derivatives (NDPDs) have been synthesized and combined with an iodonium salt, N‐vinylcarbazole, amine or 2,4,6‐tris(trichloromethyl)‐1,3,5‐triazine to produce reactive species (i.e., radicals and cations). These generated reactive species are capable of initiating the cationic polyme…
Directional attraction with lateral repulsion between colloidal nanoparticles can create their supracolloidal chains. Here, we demonstrate supracolloidal polymers of diblock copolymer micelles, which were polymerized by adjusting the polarity of the solvent. We also synthesized supracolloidal random and block copolyme…
The influence of hybrid reinforcements including silicon carbide and graphite particles with a size 37–50 μm on the wear characteristics of AZ91 magnesium alloy was studied. The dry sliding wear test was conducted using a pin-on-disc wear testing machine in the load range of 20 to 80 N at different sliding velocities…
Abstract BACKGROUND Cellulose as a renewable biomaterial has forced attention on the use of cellulose‐hydrolyzing enzymes for industrial bioconversion of lignocellulosic materials to glucose. This paper reports immobilization of cross‐linked cellulase aggregates (CLEA) on the amine‐functionalized Fe3O4@silica core‐she…
