Porousbiodegradable polymer scaffolds are widely utilized for bone tissue engineering, but are not osteoconductive like calcium phosphate scaffolds. We combine indirect solid freeform fabrication (SFF), ex vivo gene therapy, with biomineral coating to compare the effect of biomineral coating on bone regeneration for P…
NRTI: a new non-destructive neutron-based technique for the image reconstruction of the bulk elemental composition.
SERS spectra were used to distinguish tetracycline hydrochloride from the expired ones with an optical fiber nano-probe.
A recently reported synthetic method has been employed to prepare several arrays of free base and zinc porphyrins. In the arrays, the porphyrins are arranged around a central benzene ring. The lack of aryl rings in the linkages to the central benzene ring, coupled with the presence of only one meso-aryl substituent on…
Plasmonics holds promise for the realization of miniaturized photonic devices and circuits in which light can be confined and controlled at the nanoscale using surface plasmon polaritons (SPPs), surface waves of collective oscillations of electrons at a metal/dielectric interface. However, realizing plasmonic applicat…
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…
