The use of 1,8-diiodooctane (DIO) as a solvent additive in poly[N-9′-heptadecanyl-2,7-carbazole-alt-5, 5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT)-based bulk-heterojunction solar cells increased the power conversion efficiency (PCE) by 20.9%. This improvement was due to the increase in the fill factor a…
Active pharmaceutical ingredients (API) coordination complexes and networks present a promising pathway for developing new bioinspired materials. In the present study, we report several coordination networks of gabapentin with Y(III), Mn(II), and several lanthanides (LnCl 3 ), Ln = La 3+, Ce 3+, Nd 3+, Er 3+ obtained…
In this paper an experimental investigation has been carried on, in order to determinate the different damage patterns and the corresponding entity on the surface of splined couplings with straight and crowned teeth, subjected to variable working loadings. In particular, experimental tests have performed by means of a…
We show that the difference in the Seebeck coefficients between two voltage probes produces an additional electric signal in the local resistance measurement of the submicron-sized junction. This is because the temperature increase at the junction induced by the Joule heating produces unnegligible Seebeck voltage in a…
7075-T6 is one of the most performing aluminium alloys, considering its mechanical properties and good fatigue behaviour. In this work the influence of WC/C and DLC PVD coatings on the fatigue behaviour was investigated by rotating bending tests at 2·105 cycles. The fatigue behaviour of polished and untreated specimen…
The polymerization of 1-3 M 2-hydroxyethyl methacrylate (HEMA) initiated by riboflavin/triethanolamine system has been studied in the pH range 6.0-9.0. An approximate measure of the kinetics of the reaction during the initial stages (~5% HEMA conversion) has been made to avoid the effect of any variations in the volum…
Four unfilled nitrile rubber specimens with different sulfur contents were prepared, from 1.0 to 1.7 phr. The friction energy density, morphology of abraded surface, cross-linking density and fracture energy of NBR specimens were studied. Additionally, the dissipated energy by tapping mode atomic force microscopy was…
Normalized indentation works, referred to as the total and elastic energy constants, have been shown to be effective in the representation and analysis of experimental load‐displacement data. However, their physical meaning, influencing factors, variation range and relationships with other nanomechanical quantities ar…
We have analyzed magnetic-field-dependent small-angle neutron scattering (SANS) data of soft magnetic two-phase nanocomposite ferromagnets in terms of a recent micromagnetic theory for the magnetic SANS cross section [Honecker and Michels, Phys. Rev. B 87, 224426 (2013)]. The approach yields a value for the average ex…
Hexasubstituted fullerenes with the skew pentagonal pyramid (SPP) addition pattern are predominantly formed in many types of reactions and represent important and versatile building blocks for supramolecular chemistry, biomedical and optoelectronic applications. Regioselective synthesis and characterization of the new…
The activity concentrations of soil, water and fertilizer samples were determined by using high-resolution gamma spectrometry (HPGe detector: 40% relative efficiency) with a PC-based MCA system. The samples were collected from the area of a urea fertilizer factory, lagoon and Shitalakhya river in Narsingdi, Bangladesh…
Thermal analysis of planar and near-square semiconductor device chips employing angular Fourier-series (AFS) expansion is presented for the first time. The determination of the device peak temperature using AFS requires only a single two-dimensional computation, while full three-dimensional temperature distribution ca…
INTRODUCTION: The search for anti-fungal compounds has maintained a scientific interest notably due to existing difficulties in the treatment of mycoses and their increasing occurrence in hospitals. OBJECTIVE: Development of a simple method to rapidly identify anti-fungal compounds in crude plant extracts based on a H…
In this paper different characteristic parameters using high-k dielectric materials in Metal Oxide Semiconductor (MOS) device have been compared from the theoretical and simulated Capacitance-Voltage (C-V) graphs. The simulation has been done using ATLAS device simulator. The agreement of the specified values while de…
We report on fabrication of a liquid crystal (LC) electro-optic modulator in fused silica by three-dimensional (3D) femtosecond laser micromachining. The LC light modulator consists of a LC cell, four embedded microelectrodes and a buried optical waveguide, which are defined in the glass substrate simultaneously by fe…
It is shown numerically that a rotating inviscid liquid ring has a temporally oscillating state, where the radius of the ring varies periodically because of the competition between the centrifugal force and the centripetal force caused by the surface tension. Stability analysis reveals that an enlarging or shrinking r…
The computer-based design of PPIs (protein-protein interactions) is a challenging problem because large desolvation and entropic penalties must be overcome by the creation of favourable hydrophobic and polar contacts at the target interface. Indeed, many computationally designed interactions fail to form when tested i…
The kinetics and mechanisms for SiH2 + Si2H6 and SiH3 + Si2H5 reactions and the related unimolecular decomposition of Si3H8 have been investigated by ab initio molecular orbital theory based on the QCISD(T)/CBS//QCISD/6-311++G(d,p) method in conjunction with quantum statistical variational Rice-Ramsperger-Kassel-Marcu…
A combination of MALDI–TOF MS and TOF/TOF collision-induced dissociation (CID) experiments was conducted on toluene diisocyanate (TDI) based carbodiimide and phenyl isocyanate (PI) carbodiimide mixtures to examine their degradation mechanisms and identify “fingerprint” side products associated with each of their synth…
A versatile, photochemical surface-modification approach using nitrene-insertion reactions has been employed to develop an ultrathin, two-component, polymer-gradient coating. Perfluorophenyl azide (PFPA) acted as the photosensitive moiety, forming a nitrene radical upon 254 nm UV exposure. Cationic poly(allyl amine) w…
