Irradiation of three chromone-2-carboxamides with a chiral auxiliary resulted in diastereoselective formation of a C2-chiral anti-HH dimer scaffold. Selection of the solvent polarity and decreasing the temperature resulted in asymmetric induction with up to 84% diastereomeric excess (de).
Various layer traits were recorded on 1082 pullets at 29 th generation of selection to evaluate the variability for egg production. Oviposition time of each egg was recorded at hourly and half an hour intervals under 16L: 8D cycle, up to 40 weeks of age and for 15 days period respectively, to study the distribution pa…
Recently it has been shown that Chlorin e6 (Ce6) when complexed with Pluronics (hydrophilic ethylene and propylene oxide block copolymers) and poly(N-vinylpyrrolidone) (PVP) exhibits considerably higher phototoxicity towards tumor cells than free Ce6. The present work aimed to model Ce6 interactions with hydrophilic P…
Triazole-based novel dendrimers with ferrocenyl surface groups have been achieved through click chemistry, both by divergent and convergent approaches. The presence of more ferrocenyl and triazolyl units in dendrimers 1–4 alters the current potential curve in the voltammogram and also the absorption coefficient in the…
A series of giant polymer-dendron conjugates with a dendron head and a linear polymer tail were synthesized via"click" chemistry between azide-functionalized polystyrene (PS(N), N: degree-of-polymerization) and t-butyl protected, alkyne-functionalized second generation dendron (tD), followed by a deprotection process…
n- and p-type doping of MgO are induced in contact with Fe <sup>I</sup> Fe <sup>II</sup> and (Fe <sup>II</sup> ) <sub>2</sub> N terminations of Fe <sub>4</sub> N, respectively. The metallic characteristics are induced in BaTiO <sub>3</sub> by contact with Fe <sup>I</sup> Fe <sup>II</sup> termination, whereas p- and n-…
Polythiophenes functionalized with polar groups at the end of side-chain have emerged as an alternative method to obtain good compatibility between this class of conjugated polymers and electron acceptor compounds. The aim is to prevent phase segregation and to improve the efficiency of the polythiophene technological…
The stab resistance of two guide bar warp knitted fabric made from ultra-high molecular weight polyethylene was characterised by a maximum load, and energy at the maximum load and load versus displacement curves under quasi-static test conditions are presented. Penetration angles and side were designed. Samples with d…
The effect of ultrafine magnesium hydroxide (UMH) and ordinary magnesium hydroxide (OMH) on the tensile properties and flame retardancy of wood plastic composites (WPC) were investigated by tensile test, oxygen index tester, cone calorimeter test, and thermogravimetric analysis. The results showed that ultrafine magne…
Size- and shape-controlled anisotropic gold nanoparticles were reported. The organisation of tunable hydroxylated surfactants providing various nanostructured materials has been demonstrated.
Microcellular injection molding is a process that offers numerous benefits due to the internal structure generated; thus, many applications are currently being developed in different fields, especially home appliances. In spite of the advantages, when changing the manufacturing process from conventional to microcellul…
<sc>l</sc> -Phenylalanine imprinting chiral ordered mesoporous silica ( <sc>l</sc> -Phe-COMS) was endowed with unique structural features, showing a high stereoselective adsorption factor of up to 3.24 for <sc>l</sc> -phenylalanine over <sc>d</sc> -phenylalanine.
Herein we present an assessment to determine which of nine well-established DFT functionals best describes the reduction of C2H2Se2(-)˙. In addition, we have also studied the effects of changing the substituents bound to the alkene functional group of dithiolene and diselenolene ligands. Such ligands are important due…
Ni–Co complexes are prepared using cobalt coordination complex as precursors by nickel exchange method. Single-crystal to single-crystal transformation had been achieved. Using Ni–Co complex as the precursors, we have synthesized a series of 3D hierarchical Ni <sub>x</sub> Co <sub>3−x</sub> S <sub>4</sub> microflowers…
AIM: The aim of this work was to synthesize and study in vitro and in vivo nanocarriers used as magnetic resonance imaging (MRI) contrast agents that accumulate in tumor cells specifically overexpressing folate receptors. MATERIALS AND METHODS: Nanoparticles were prepared by self-assembly of poly-γ-glutamic acid and c…

A new alkaline beryllium borate, KBe <sub>4</sub> B <sub>3</sub> O <sub>9</sub> , consisting of 2D ribbon alveolate beryllium borate [Be <sub>2</sub> BO <sub>5</sub> ] <sub>∞</sub> layers connected by strong covalent bonds.
Mesoporous polyacrylamides (PAMs) with tunable porosities were synthesized in 1-alkyl-3-methylimidazolium tetrafluoroborates ([Cnmim][BF4], n = 4, 6, 8, 10). The as-synthesized PAM was used as a support for Pd nanoparticles and the Pd/PAM composite showed high catalytic activity and selectivity for the hydrogenation o…
We review deviational methods for solving the Boltzmann equation governing phonon transport processes in the context of small-scale, solid-state heat transfer. We briefly discuss the numerical foundations of deviational algorithms as well as basic simulation methodology. Particular emphasis is given to recent developm…
Ultrafine-grained (UFG) pure copper of 280 nm grain size was prepared by equal-channel angular pressing. Tensile tests, strain-rate change tests and temperature change tests were conducted on UFG Cu in the temperature range between 77 K and 373 K. As usual, tensile strength increased as temperature decreased and strai…
