Thin ion-beam (IB)-spurted dimethyl sulfate/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (DMS/PEDOT:PSS) layers with improved electro-optic performance are presented for aligning liquid crystals. IB spurting is effective for enhancing the conductivity of such layers, as well as the anchoring energy of the li…
The crystalline (B4 ) phase made of acute-angle bent-core molecules (1,7-naphthalene derivatives), which exhibits an unusual, highly porous sponge-like morphology, is presented. However, if grown in the presence of low-weight mesogenic molecules, the same crystal forms nanotubes with a very high aspect ratio. The nano…
An accurate quantification method for hydroxyl (OH) radicals is proposed. A pulsed plasma was generated in argon over a solution of disodium terephthalate (NaTA) or 2-hydroxyterephthalic acid (HTA). Since it was confirmed that HTA could be decomposed by the plasma, rate equations for NaTA and HTA were calculated using…
Luminescence nanothermometry is nowadays a highly‐dynamic research topic that is being driven by the challenging demands arising from dissimilar areas such as microelectronics, microfluidics and nanomedicine. Although the technique is rapidly evolving from the initial breakthrough to real applications, there are still…
Energy filtering effect is usually utilized in composites to enhance the thermoelectric performance, and a reliable theoretical approach is needed to predict the optimum parameters related to this effect. By taking Bi2Te3 as an example, we show that first principles calculations and Boltzmann transport equations can b…
Nanoparticles with well-defined interfacial energy and wetting properties are needed for a broad range of applications involving nanoparticle self-assembly including the formation of superlattices, stability of Pickering emulsions, and for the control of nanoparticle interactions with biological membranes. Theoretical…
We report on optical examination of structural properties of cubic-In 2 O 3 ( c -In 2 O 3 ) degenerate-semiconducting-oxide thin-film nanostructures grown on Si (100) substrates using vapor transport method driven with vapor–liquid–solid mechanism. Two different types of dense (A) and loose (B) c -In 2 O 3 thin-film n…
The first experimental observation of the piezoelectricity of graphene oxide (GO) papers is performed. Polar domains are observed using piezoelectric force microscopy, and the domain switching behaviors under external electric fields are investigated. The piezoelectricity is proved to be induced by the H-bonds between…
Enrichment schemes providing high-purity semiconducting single-walled carbon nanotubes (sc-SWCNTs) will enable their implementation into high end and printed electronics. Conjugated polymer extraction (CPE) has been shown to be a very effective and scalable method to isolate sc-SWCNTs with purities >99.9%. However, th…
Early detection and appropriate management of chronic kidney disease can reduce the progression of kidney failure and cardiovascular disease. The urine albumin to creatinine ratio (UACR) test is a standard urine test for identifying individuals at high risk of developing progressive kidney disease. In this study, IDAT…
In this letter, we report on the fluorescence lifetime imaging and accompanying photoluminescence properties of a chemical vapour deposition (CVD) grown atomically thin material, MoS2. µ‐Raman, µ‐photoluminescence (PL) and fluorescence lifetime imaging microscopy (FLIM) are utilized to probe the fluorescence lifetime…
Four new copper complexes based on bidentate imino phenoxide ligands were synthesized and characterized by IR, UV–Vis spectroscopy, ESI mass spectrometry, single crystal X-ray diffraction, and electrochemistry. The crystal structures revealed that the copper(II) atoms are surrounded by phenolate oxygen and imine nitro…
The reactions of the tripodal tetradentate ONNO donor ligands 6,6′‐{[(2‐morpholinoethyl)azanediyl]bis(methylene)}bis(2,4‐di‐tert‐butylphenol) (H2L1), 6,6′‐{[(2‐morpholinoethyl)azanediyl]bis(methylene)}bis(2,4‐dimethylphenol) (H2L2) and 6,6′‐{[(2‐morpholinoethyl)azanediyl]bis(methylene)}bis[2‐(tert‐butyl)‐4‐methylpheno…
Yttria-stabilized zirconia (YSZ) thin film electrolyte deposited by plasma enhanced atomic layer deposition (PEALD) was investigated. PEALD YSZ-based bi-layered thin film electrolyte was employed for thin film solid oxide fuel cells on nanoporous anodic aluminum oxide substrates, whose electrochemical performance was…
Abstract A spiropyran‐based switchable ligand isomerizes upon reaction with lanthanide(III) precursors to generate complexes with an unusual N3O5 coordination sphere. The air‐stable dysprosium(III) complex shows a hysteresis loop at 2 K and a very strong axial magnetic anisotropy generated by the merocyanine phenolate…
With the addition of small molecules to emulsion droplets containing block copolymers, anisotropic convex lens-like particles with hexagonally stacked cylindrical domains can be readily achieved by using a single surfactant to create a neutral interface for both blocks.
Requisite to growing stoichiometric perovskite thin films of the solid-solution A′1-xAxBO3 by hybrid molecular beam epitaxy is understanding how the growth conditions interpolate between the end members A'BO3 and ABO3, which can be grown in a self-regulated fashion, but under different conditions. Using the example of…
The influence of different parameters on magnesium oxychloride cement (MOC) was investigated in this study. The use of experimental design was found to be very beneficial for determining suitable experimental conditions to obtain a better composition of cement. The studied factors used to model and optimise the operat…
In this paper, we substantiate the claim implicitly made in previous works that the relaxed micromorphic model is the only linear, isotropic, reversibly elastic, nonlocal generalized continuum model able to describe complete band-gaps on a phenomenological level. To this end, we recapitulate the response of the standa…
Ion exchange, in which an in-diffusing ion replaces a lattice ion, has been widely exploited as a synthetic tool for semiconductor doping and solid-to-solid chemical transformations, both in bulk and at the nanoscale. Here, we present a systematic investigation of cation-exchange reactions that involve the displacemen…
