Using Raman spectroscopy and lysozyme, this latter as model protein, we investigate the differences in protein conformation before and after LB nanotemplate-induced crystal nucleation and growth. It was found that the main difference in lysozyme conformation is associated to the higher amount of S-S bonds in lysozyme…
We report the first synthesis of a soluble selenophene containing porphyrazine derivative, tetraselenophenoporphyrazine (SePz). Thin films of SePz exhibit a broad and strong absorption in the visible to near-IR region, which is red shifted compared to the thiophene analogue, and demonstrate p-type carrier mobilities o…
The aqueous RAFT copolymerization of methacrylamide- and methacrylate-functionalized (1→4)-α-L-guluronan and (1→4)-β-D-mannuronan macromonomers with N-(2-hydroxyethyl)methacrylamide afforded synthetic-g-polysaccharide copolymers with a predetermined and well-defined molar mass (“grafting through” approach). One such p…
Herein we describe the synthesis, structural and magnetic characterisation of three transition metal cluster complexes that feature the polytopic ligand N-(2-pyridyl)-3-carboxypropanamide (H2L): [Fe3(III)Fe2(II)(HL)6(O)(H2O)3][ClO4]5·3MeCN·4H2O, 1, [Co8(HL)8(O)(OH)4(MeOH)3(H2O)]-[ClO4]3·5MeOH·2H2O, 2, and [Cu6(L(ox))4…
Covalently linked BF 2 -oxasmaragdyrin-BODIPY and BF 2 -oxasmaragdyrin-ferrocene dyads were synthesized by coupling of meso-triaryl oxasmaragdyrin containing meso-iodophenyl group with meso-(p-ethynylphenyl) borondipyrromethene and α-ethynyl ferrocene respectively under mild Pd(0) coupling conditions. NMR, absorption…
To fully understand the thermodynamic nature of polymer blends and accurately predict their miscibility on a microscopic level, a hybrid model employing both statistical mechanics and molecular dynamics techniques was developed to effectively predict the total free energy of mixing. The statistical mechanics principle…
Indium tin oxide (ITO) films were deposited on glass substrates by using the homemade injection ultrasound spray pyrolysis system. Orthogonal test was designed to examine the optimal conditions for preparation of the ITO films. The results showed that the ITO thin films can be prepared by the homemade injection ultras…
As energy storage devices, Supercapacitors (SCs), also known as electrochemical capacitors, possess high power densities, excellent reversibility and long cycle life. SCs could be applied to diverse fields including electric vehicles, pulse power applications and portable devices. Flexible SCs have attracted significa…
Silicon carbide N H-SiC polytypes with N = 2, 4, 6, and 8 are considered as substrates for the epitaxial formation of graphene. The density of states for the substrates is described using the Haldane-Anderson model. It is shown that this model always leads to the appearance of two gaps in the graphene spectrum, which…
A new Li–Sr–Nb phosphate series of glasses, Li2O–SrO–Nb2O5–P2O5, containing 0–40 mol% Li2O and 10–30 mol% Nb2O5 was prepared, and their structural properties, thermal properties and aqueous durability were systematically investigated. With addition of 0–30 mol% Li2O, the Q2 dominates the glass network accompanied with…
Porphyrins have been used by various researchers as important building blocks of photofunctional molecules, while the number of studies on the excitation properties of the structural isomers of porphyrins is small when compared to those of porphyrins. In the present study, photoinduced electron transfer (ET) processes…
An artificial neural network model has been developed for predicting the perforation limits of spaced aluminum armor (aka Whipple shield) under impact of aluminum projectiles at hypervelocity. The network, utilizing a multilayer perceptron architecture, was trained on data from 769 impact tests, for which it accuratel…
The aging of dielectric properties of Cr-Doped Pb(Zr0.52Ti0.48)O3 were investigated. The composition of Pb(Zr0.52Ti0.48)O3 with 0.1, 0.2, 0.4, 0.6, 1.0 and 3.0 mol% of Cr2O3 addition were prepared by conventional mixed oxide technique. The aging has been measured at room temperature after quenching from high temperatu…
Polydentate ligands were used to support planar methoxo-bridged {Ni(6-x)Co(x)} (x = 0, 1 or 2) clusters which were structurally characterized by single crystal analyses. The homometallic {Ni6} complex displayed overall ferrimagnetic interactions between metal centres, and increasing the cobalt content led to a proport…
The objective of the paper was performing of the sensitivity analysis of the model used for design of manufacturing technology for auto body parts made of the Advanced High Strength Steels (AHSS). Dual phase steel was considered as an example. The sensitivity analysis was performed to evaluate the importance of all va…
The one- and two-photon absorption characteristics of the Porphyrin isomers Porphycene, Corrphycene, Hemiporphycene, N-confused Porphyrin, cis- and trans-Doubly confused Porphyrins, the newly synthesised Neo-confused Porphyrin, and a set of core-substituted Porphycenes are systematically investigated using linear and…
This paper presents the results of electric field and potential distributions simulation along surface of silicone rubber polymer insulators. Finite element method (FEM) is adopted for this paper. Identification of the electrical field and the potential distributions at the dielectric insulation has always been import…
Single‐walled carbon nanotubes (SWNTs) have been synthesized via a novel chemical vapor deposition (CVD) approach utilizing nanoporous, iron‐supported catalysts. Stable aqueous dispersions of the CVD‐grown nanotubes using an anionic surfactant were also obtained. The properties of the as‐produced SWNTs were characteri…
Ferritic oxide dispersion strengthened (ODS) alloy and stainless steel are attractive candidates for applications in the high temperature industries. Friction stir welding (FSW) is a very promising technique for the joining of both materials. Severe shear deformation and high heat input during FSW process can signific…
The nanowire with an aspect ratio of 3 : 1 possesses a higher bending stress of 15.85 GPa. It can be observed that the initial Si-Si bond and N atom defects with a coordination number of 2, subsequently evolving to 0 and 1, with Si evolving from 5 to 6 and 7, are mainly responsible for the final fracture.
