Diamond is a unique material with several outstanding physical and chemical properties. It has the highest thermal conductivity at room temperature and it is transparent from the UV to the far IR. Furthermore it has the highest hardness, the highest Young's modulus and it is chemically inert and radiation hard. These…
The addition of zero-valent copper to the self-condensing vinyl polymerization (SCVP) of novel AB* (meth)acrylic monomers using atom transfer radical polymerization (ATRP) catalyst systems has allowed for their successful polymerization. Polymerization under homogeneous and heterogeneous catalyst conditions without ad…
The fundamental physical phenomena on which LEEM is based are discussed, with the goal of showing why LEEM works, not how it works. The subjects covered include intensity, resolution, contrast, sampling depth and combination possibilities with other techniques (particularly LEED) which make LEEM a unique surface imagi…
The phase behavior of a styrene–isoprene (SI) diblock copolymer, with block molecular weights of 1.1 × 104 and 2.1 × 104 g/mol, respectively, is examined in the neutral solvent bis(2-ethylhexyl) phthalate (DOP) and the styrene-selective solvent di-n-butyl phthalate (DBP). DBP is a good solvent for PS, but is near a th…
All-plastic and flexible electrochromic devices will facilitate new technological applications, such as information display and storage, in the automotive industry (rear-view mirrors) and in architecture (smart windows). Here the authors describe an all-plastic and flexible solid-state electrochromic device using two…
In this work a method is developed that allows the computation of the single-crystal elastic constants for crystals of cubic symmetry from the diffraction elastic constants. The diffraction elastic constants can be obtained by measuring the hkl -dependent lattice strain response to an applied stress. Because of their…
The photochromic behavior of several spirooxazines (SO) containing phenanthrene or phenanthroline moieties in the oxazine part of molecules has been investigated in several solvents and phosphatidylcholine (PC) liposomes. The solvatochromic properties of the merocyanine (MC) forms of these dyes were used to probe thei…
We present a model for treating solid boundaries of a DPD fluid. The basic idea is to model the stick boundary conditions by assuming that a layer of DPD particles is stuck on the boundary. By taking a continuum limit of this layer effective dissipative and stochastic forces on the fluid DPD particles are obtained. Th…

The following dinuclear exchange-coupled manganese complexes are investigated: [dtneMn III Mn IV (μ-O) 2 μ-OAc](BPh 4 ) 2 (dtne = 1,2-bis(1,4,7-triazacyclonon-1-yl)ethane), [(CH 3 ) 4 dtneMn III Mn IV (μ-O) 2 μ-OAc](BPh 4 ) 2 ((CH 3 ) 4 dtne = 1,2-bis(4,7-dimethyl-1,4,7-triazacyclonon-1-yl)ethane), [(CH 3 ) 4 dtneMn I…
Light-scattering spectra of the glasses polystyrene (PS), polycarbonate (PC), and ${\mathrm{Ca}}_{0.4}{\mathrm{K}}_{0.6}({\mathrm{NO}}_{3}{)}_{1.4}$ (CKN) are measured in the frequency interval $3\ensuremath{-}10000 \mathrm{GHz}$ covering a broad temperature range. The low frequency wing of the fast relaxation spectru…
Abstract Biodegradable polymers constitute a loosely defined family of polymers that are designed to degrade through the action of living organisms. They offer a possible alternative to traditional nonbiodegradable polymers if recycling is impractical or not economical. The main driving force behind this technology is…
The soil-dwelling microbe, Pseudomonas sp. strain CBS-3, has attracted recent attention due to its ability to survive on 4-chlorobenzoate as its sole carbon source. The biochemical pathway by which this organism converts 4-chlorobenzoate to 4-hydroxybenzoate consists of three enzymes: 4-chlorobenzoyl-CoA ligase, 4-chl…
Most apparel sizing systems are based on one or two body dimensions and rely on assumptions about proportional body relationships to project other dimensions necessary to design the garment pattern. Garments from these systems will not fit a population with large variations in body proportions. Using nonlinear optimiz…
A series of metal bis-mnt complexes (mnt = 1,2-dithiolatomaleonitrile) with the trimethylammonium methylferrocene cation have been synthesized and characterized using X-ray diffraction, magnetic susceptibility, and differential scanning calorimetry measurements. The complexes have the formulas (FcCH(2)NMe(3))[Ni(mnt)(…
We consider a fluid of hard boomerangs, each composed of two hard spherocylinders joined at their ends at an angle ψ. The resulting particle is nonconvex and biaxial. The occurence of nematic order in such a system has been investigated using Straley's theory, which is a simplificaton of Onsager's second-virial treatm…
Magnetite single crystals ${\mathrm{Fe}}_{3\ensuremath{-}x}{M}_{x}{\mathrm{O}}_{4}$ doped with $M=\mathrm{Ni},$ Co, Mg, Al, Ga, and Ti were grown and annealed under a controlled atmosphere to produce homogeneous and oxygen stoichiometric samples. The cation vacancy concentration of the samples was proved to be lower t…
The structures of the acid-paste-prepared α-form of cobalt phthalocyanine (α-PcCo) and of its corresponding β-form (β-PcCo) have been refined through X-ray powder diffraction using the Rietveld method. The α-polymorph is triclinic, space group P 1̄, cell parameters a = 12.090(8) Å, b = 3.754(2) Å, c = 12.800(9) Å, α =…
Mitochondrial complexes I, II, and III were studied in isolated brain mitochondrial preparations with the goal of determining their relative abilities to reduce O2 to hydrogen peroxide (H2O2) or to reduce the alternative electron acceptors nitroblue tetrazolium (NBT) and diphenyliodonium (DPI). Complex I and II stimul…
The atomic structure of lead zirconate, PbZrO 3 (PZ), was studied using Rietveld refinement and atomic pair distribution function analysis of pulsed neutron powder diffraction data for the antiferroelectric, intermediate and paraelectric phases. The symmetry of PZ at T = 20 K in the antiferroelectric phase was determi…
