The effect of dendritic substituents on a nonlinear optical chromophore for power limiting (OPL) has been investigated. Synthesis and characterization bis((4-(phenylethynyl)phenyl)ethynyl)bis(tributylphosphine)platinum(II) with end groups are described. Polyester dendrimers up to the fourth generation were grown divergently using anhydride 2,2-bis(methylol)propionic acid (bis-MPA). introduction moieties onto NLO enables further processing materials polymeric related techniques. OPL...
AlCr-based hard nitride coatings with different chemical compositions and architectures have been successfully developed applied over the last few decades. Coating properties are mainly influenced by deposition conditions Al/Cr content. The fcc structure is dominant for an Al-content up to Al0.7Cr0.3N preferred most cutting applications. Different (AlCrX)N alloying concepts, including X = Si, W, B, V, investigated in order enhance oxidation resistance wear behaviour provide tribological...
DC arc plasma from Ti, Al, and Ti1-xAlx (x = 0.16, 0.25, 0.50, 0.70) compound cathodes was characterized with respect to chemistry charge-state-resolved ion energy. Scanning electron microscopy, X-ray diffraction, Energy-dispersive spectroscopy of the deposited films cathode surfaces were used for exploring correlation between cathode-, plasma-, film composition. Experimental work performed at a base pressure 10−6 Torr, exclude plasma-gas interaction. The composition showed reduction Al...
Abstract It is well known that surface energy differences thermodynamically stabilize nanocrystalline γ-Al 2 O 3 over α-Al . Here, through correlative ab initio calculations and advanced material characterization at the nanometer scale, we demonstrate metastable phase formation of TiAlN, an industrial benchmark coating material, crystallite size-dependent. By relating calculated volume contributions to total energy, predict chemical composition-dependent boundary between two solid solution...
A model equation governing the amplitude of electric field in an array coupled optical waveguides embedded a material with Kerr nonlinearities is derived and explored. The extended discrete nonlinear Schrödinger intersite nonlinearities. Attention turned towards localized solutions investigations are made from viewpoint theory breathers (DBs). Stability analysis reveals inversion stability between stationary one-site symmetric or antisymmetric two-site connected to bifurcations pair...
Arc plasma from Ti-C, Ti-Al, and Ti-Si cathodes was characterized with respect to charge-state-resolved ion energy. The evaluated peak velocities of different species in generated a compound cathode were found be equal independent on mass. Therefore, measured difference kinetic energies can inferred the mass, no dependence charge state. latter is consistent previous work. These findings explained by quasineutrality, acceleration pressure gradients, electron-ion coupling. Increasing C...
We investigate the effect of continuous vs. periodically interrupted plasma exposure during cathodic arc evaporation on elastic modulus as well residual stress state metastable cubic TiAlN coatings. Nanoindentation reveals that grown at floating potential with is 7%–11% larger than for coatings due to substrate rotation. In combination X-ray analysis, it evident governed by state. The experimental dependence in excellent agreement ab initio predictions. macroparticle surface coverage...
Optical power limiting and luminescence properties of two Pt(II) complexes with thiophenyl phenyl groups in the ligands, trans-Pt(P(n-Bu)3)2(C[triple bond]C-Ar)2, where Ar = -C4H2S-C[triple bond]C-p-C6H4-n-C5H11 (1) -p-C6H4-C[triple bond]C-C4H3S (2), have been investigated. The fluorescence lifetimes were found to be on sub-nanosecond time scale, quantum yields low, accord fast intersystem crossing from excited singlet triplet manifold. phosphorescence 1 2 shorter than that a complex having...
Arc plasma from Ti-Si compound cathodes with up to 25 at. % Si was characterized in a DC arc system respect chemistry and charge-state-resolved ion energy. The composition showed lower content, diverging 12 compared the cathode composition, yet concurrently deposited films were accordance stoichiometry. Significant contribution film growth neutrals is inferred besides ions, since macroparticles, estimated by scanning electron microscopy, cannot alone account for compositional difference...
The microstructural evolution of Ti1−xSix cathode surfaces (x=0,0.1,0.2) used in reactive cathodic arc evaporation has been investigated by analytical electron microscopy and x-ray diffractometry. results show that the operated N2 atmosphere induces a 2–12 μm thick N-containing converted layer consisting nanosized grains two-phase Ti Ti5Si3 surface. formation mechanism this is proposed to be surface nitriding redeposition macroparticles formed during deposition process. roughness worn...
Unnatural deaths among Indigenous populations, including the Swedish Sami, occur more often than general population. To find prevention strategies, we explored circumstances of unnatural members reindeer-herding Sami families.The number from a cohort 7,482 families were retrieved National Board Health and Welfare for years 1961- 2001.An evaluation information autopsy records at Forensic Medicine, police reports, available medical identified 158 deaths. These then analysed in...
Liquid crystalline dendrimers with peripheral mesogen-containing units have been prepared. Multistep synthesis several selective reactions was used in the preparation of molecules, 4‘ ‘-[10-(hydroxycarbonyl)decyloxy]phenyl 4-[4‘-(2-(R)-octyloxy)-3‘-nitrophenyl]benzoate and ‘-[10-(hydroxycarbonyl)decyloxy]biphenyl 4-[4‘-(2-(R)-octyloxy)-3‘-nitrophenyl]benzoate. Both molecules possessed an electron-accepting nitro group placed perpendicular to long axis order enhance nonlinear optical...
In our search for the definition of new molecular compounds combining low linear absorption with high nonlinear optical in same wavelength range, we have prepared a series vanadyl, chloroindium and lead naphthalocyaninato complexes relatively within visible range when compared to phthalocyanines, but similar chemical stability. The transmission properties these nanosecond pulses at 532 nm been evaluated confronted both regimes. Halogenated naphthalocyanines displayed best optical-limiting...
In Sweden and in other countries, it has become increasingly common to view violence from a public health perspective.This chapter presents description of interpersonal with an emphasis on close relations, particularly partner relationships.According the Swedish Crime Survey 2010, approximately one ten inhabitants was exposed violence, threats or harassment some kind 2009.Young people single mothers small children are vulnerable violence.According Statistics Sweden's ULF surveys (Survey...
