Abstract In this work, experiments using a pendulum apparatus were conducted for two particles engaged in oblique, wetted collisions over a range of impact angles, impact velocities, coating thicknesses, liquid viscosities, particle materials, and particle radii. From previous studies on normal or head-on collisions,…
Chloride anion attachment has previously been shown to aid determination of saccharide anomeric configuration and generation of linkage information in negative ion post-source decay MALDI tandem mass spectrometry. Here, we employ electron detachment dissociation (EDD) and collision activated dissociation (CAD) for the…
In the present study, we use composite methods, denoted CM(5)Λ and CM5, with post-CCSD(T) terms up to CCSDTQ(5)Λ and CCSDTQ5, respectively, to evaluate the atomization energies for CrO, CrO2, and CrO3. The heats of formation (ΔHf,298) based on our best estimated atomization energies are 198.3 ± 5 kJ mol(-1) (CrO), -81…
The photophysics and photochemical reactions of 2-(1-hydroxyethyl) 9,10-anthroquinone (2-HEAQ) were studied using femtosecond transient absorption (fs-TA), nanosecond transient absorption (ns-TA), and nanosecond time-resolved resonance Raman (ns-TR(3)) spectroscopy techniques and density functional theory (DFT) calcul…
A series of four tripodal phosphine oxide ligands, (OPR(2))(2)CHCH(2)POR(2) (1a-1d), and four mixed phosphine-phosphine oxide ligands, (OPR(2))(2)CHCH(2)PR(2) (3a-3d), were synthesized and coordinated to yttrium to produce Y(NO(3))(3)[(OPR(2))(2)CHCH(2)POR(2)] (2a-2d) and Y(NO(3))(3)[(OPR(2))(2)CHCH(2)PR(2)](OPPh(3))…
We develop an approach for dynamical (ω > 0) embedding of mixed quantum mechanical (QM)/classical (or more precisely QM/electrodynamics) systems with a quantum sub-region, described by time-dependent density functional theory (TDDFT), within a classical sub-region, modeled here by the recently proposed near-field (NF)…
New properties, earlier unknown for calixarenes, were found for tert-butylthiacalix[4]arene (1) clathrate with 1,2-dichloroethane (DCE). Guest exchange in 1·1.90DCE for vapors of some organic compounds gives clathrates, which are more thermostable at 34-59 °C than those prepared by direct saturation of guest-free 1 wi…
A suspended, doubly clamped single-wall carbon nanotube is characterized at cryogenic temperatures. We observe specific switching effects in dc-current spectroscopy of the embedded quantum dot. These have been identified previously as nano-electromechanical self-excitation of the system, where positive feedback from s…
Neutral diastereoisomeric diruthenium(III) complexes, meso- and rac-[(acac)(2)Ru(μ-adc-OR)Ru(acac)(2)] (acac(-) = 2,4-pentanedionato and adc-OR(2-) = dialkylazodicarboxylato = [RO(O)CNNC(O)OR](2-), R = tert-butyl or isopropyl), were obtained from electron transfer reactions between Ru(acac)(2)(CH(3)CN)(2) and azodicar…
Agro-industrial by-products are important sources of potent bioactive phenolic compounds. These compounds are of extreme relevance for food and pharmacological industries due to their great variety of biological activities. Fermentation represents an environmentally clean technology for production and extraction of th…
Two novel high-specific surface area polymeric sorbents (HXLPP-SAXa and HXLPP-SAXb) were synthesised and evaluated as solid-phase extraction sorbents. The novel sorbents under study are based on hypercrosslinked polymer microspheres and designed specifically to offer ion-exchange properties; the specific polymers of i…
The pentapeptide Cys-Ala-Leu-Asn-Asn (CALNN) has been proved to be a powerful tool to stabilize the AuNPs. These CALNN-capped AuNPs have been used to develop various bioanalysis platforms. In this paper, the CALNN-capped AuNPs are proved to be a robust tool for aggregation-based colorimetric immunoassays as well. A co…
The information content in 1-D solution X-ray scattering profiles is generally restricted to low-resolution shape and size information that, on its own, cannot lead to unique 3-D structures of biological macromolecules comparable to all-atom models derived from X-ray crystallography or NMR spectroscopy. Here we show t…
The isothermal oxidation behaviour of silicon and copper containing steels was studied under laboratory dry air conditions at temperatures from 950 to 1180°C. The oxidation kinetics was determined by gravimetric means and followed by parabolic relationships at all temperatures for both steels. Characterisation of the…
Novel magneto-optical thin films composed of europium sulfide (EuS) nanoparticles on a glass electrode exhibit large magneto-optical efficiency and a wide energy gap. EuS nanoparticle thin films are prepared by the electrochemical reduction of a single-source precursor, a Eu(III) dithiocarbamate complex (tetraphenylph…
Abstract AD (Alzheimer’s disease) is a progressive neurodegenerative disorder characterized by the cerebral accumulation of fibrillar amyloid‐beta (Aβ) aggregates. Here we present the electrochemistry of two novel sym‐triazine derivatives (TAE‐1, TAE‐2) as modulators of Aβ1–42 aggregation in vitro. Incubation studies…
This paper presents the results of an experimental investigation conducted to study the strength of different repair technique on impact damaged glass fibre reinforced plastics (GFRP) using the acoustic emission technique. ASTM D3039 tensile specimens (250 mm × 18 mm × 2 mm) fabricated using bi-directional glass fibre…
Trickreiches Triggern: Durch Wirt-Gast-Komplexierung von Pyren-markierten Peptiden und Viologenlipid mit Cucurbit[8]uril wurden supramolekulare Peptidamphiphile hergestellt. Die Amphiphile selbstorganisieren zu Vesikeln, die auf verschiedene externe Auslösereize ansprechen. Ein An- und Ausschalten der Fluoreszenz und…
The crossover region in the phase diagram of polymer solutions, in the regime above the overlap concentration, is explored by Brownian dynamics simulations to map out the universal crossover scaling functions for the gyration radius and the single-chain diffusion constant. Scaling considerations, our simulation result…
An interleaved electromagnetic bandgap (EBG) structure is investigated to be with a compact size and wide stopband bandwidth for suppressing power/ground noise in power distribution networks. A design concept of the interleaved EBG structure is given to improve both lower and upper bound cutoff frequencies through var…
