GaN has been utilized in optoelectronics for two decades. However, p-type doping still remains crucial for realization of high performance GaN optoelectronics. Though Mg has been used as a p-dopant, its efficiency is low due to the formation of Mg-H complexes and/or structural defects in the course of doping. As a pot…
Abstract The wave functions for calculating 13C nuclear magnetic chemical shifts of 22 groups of organic compounds (64 molecules) in chloroform solution have been optimally selected using factorial design as a multivariate technique. Our own N‐layered integrated molecular orbital and molecular mechanics approach was a…
Photodriven electron-transport properties of the self-assemblies of N,N'-di(2-(trimethylammoniumiodide)ethylene)perylenediimide stacks (TAIPDI)(n) with three electron donors, disodium 4,4'-bis(2-sulfonatostyryl)biphenyl (BSSBP, stilbene-420), sodium 9,10-dimethoxyanthracene-2-sulfonate (DANS) and disodium 6-amino-1,3-…
A novel subtractively normalized interfacial Fourier transform infrared spectroscopic (SNIFTIRS) investigation of anodically polarized nickel electrodes in pseudohalide-containing DMF or DMSO solutions (i.e. OCN − , SCN − , SeCN − ), in supporting electrolyte, tetrabutylammonium perchlorate (TBAP), is presented. In ge…
Selective hydrogenation and ring opening (SRO) of tetrahydronaphthalene (tetralin) was studied over nickel and iridium supported catalysts in the context of the removal of polynuclear aromatics from diesel fuel. The tetralin hydrogenation was carried out in a fixed‐bed reactor at 270°C, using H2 pressure of 30 bars, W…
Modern technology of concrete includes a comprehensive elaboration of proposal related to concrete composition depending on the required parameters of fresh and hardened concrete. One of the fields related to the technologies of concrete is the issue of the generation of hydration heat. Heat generation in the process…
Four Cu(II) complexes, 1, 2, 3 and 4, are synthesized with ligands, L1, L2, L3 and L4 [L1 = N1,N2-bis((pyridin-2-yl)methyl)ethane-1,2-diamine; L2 = N1,N3-bis((pyridin-2-yl)methyl)propane-1,3-diamine; L3 = N1,N1,N2-tris((pyridin-2-yl)methyl)ethane-1,2-diamine; L4 = N1-((1-methyl-1H-imidazol-2-yl)methyl)-N1,N2-bis((pyri…
The cold atmospheric plasma (CAPs) is the fourth state of matter, which means that it is an ionized gas, obtained at room temperature and atmospheric pressure when energy is supplied to a gas. Its composition is complex, involving chemical (gas's molecules, free radicals, ions and electrons) and physical (Ultra-violet…
A novel type of phosphonate-containing polystyrene copolymers 1a-e bearing an N'-alkylated TsDPEN chiral ligand and double-stranded polystyrene chains were prepared for the first time using simple radical copolymerization of 1-phosphonate styrene with (R,R)-N'-4'-vinylbenzyl-N-4-vinylbenzenesulfonyl-1,2-diphenylethyle…
Two novel entangled coordination polymers, [Zn(abda)(bimh)]n (1) and [Cd(dtba)(bimh)]n (2) (H2abda = azobenzene-4,4′-dicarboxylic acid, H2dtba = 2,2′-dithiobisbenzoic acid, bimh = 1,6-bis(2-methylimidazole-1-yl)hexane), have been synthesized using long mixed ligands. Complex 1 features rare 2D parallel interpenetrated…
A LiMnPO4–LiMn2O4 (LMP–LMO) nanocomposite cathode is synthesized by a one-step polyol-assisted pyro-synthesis followed by mild annealing for rechargeable lithium-ion batteries. The LMP–LMO cathode delivered an initial discharge capacity of 142 mA h g−1 and also maintains about 90% capacity retention for over 50 electr…
We have carried out in-situ measurements of Si cluster volume fraction in Si films during plasma chemical vapor deposition by using quartz crystal microbalances (QCM's) together with a cluster-eliminating filter. The cluster volume fraction in films is deduced from film deposition rates with and without Si clusters us…
Atomic physics has played an important role throughout the history of experimental plasma physics. For example, accurate knowledge of atomic properties has been crucial for understanding the plasma energy balance and for diagnostic development. With the shift in magnetic fusion research toward high-temperature burning…
A three-dimensional (3D) heterometallic metal–organic framework containing cubic-like cages, namely {[Co3Na6(TzDC)4(H2O)6]·7H2O}n (1) (H3TzDC = 1,2,3-triazole-4,5-dicarboxylate), has been synthesized by the edge-directed self-assembly of TzDC3−, Co2+ and Na+ ions. Crystal data reveals that one hydrous Co2+ cation is e…
Self‐assembly of colloidal spheres is the most frequently used method for structural colors, but the chroma of the structural colors is usually so low that people cannot observe it under natural conditions. This paper presents a facile method for fabrications of vivid structural colors by doping carbon black into the…
It is often in the interest of a designer to know the transient state of stress in a plate subjected to an underwater explosion. In this paper, an analytical method based on Taylor’s fluid-solid interaction (FSI) model, Mindlin plate theory, Laplace transform, and its inversion is proposed to examine the elastic dynam…
The spontaneous self-assembly of a novel comb-like amphiphilic copolyelectrolyte in water was studied by small angle neutron scattering and freeze fracture transmission electron microscopy. The copolymer was synthesized by randomly grafting pendant quaternized alkylamine moieties to a poly(styrene) chain. The effects…
Novel curcumin analogues with α,β-unsaturated ketone moiety and/or α,β-saturated ketone structure were synthesized from curcumin via alkylation at the central carbon and the phenolic hydroxy groups, and hydrogenation of α,β-unsaturated ketone moiety. The antiproliferative activities were tested in five human solid tum…
This study reveals that a dipropargyl rhodamine B derivative previously described as a reaction-based irreversible palladium probe responds, however, more sensitively to mercury with a reversible "turn-on" fluorescence. The probe also shows a much better imaging ability for mercury than for palladium in live cells.
Following a simple thermodynamic model, which predicts that an array of non-wettable pores can be filled by dewetting of sufficiently thin films, we use molecular dynamics to simulate the rupture of nanometre-thick liquid Au films on nanoporous substrates. Our simulations clearly exhibit spinodal dewetting and hole nu…
