Glycal-based bolaforms serve as synthetically flexible components of molecular self-assembly. The compounds are prepared in good yield by a Ferrier reaction between triacetylglucal or -galactal or diacetylxylal and a long chain alpha,omega-diol, followed by deacetylation under Zemplen conditions. The reactions are ste…

In the automated image analysis of crystallization experiments, representative examples of outcomes can be obtained rapidly. However, while the outcomes appear to be diverse, the number of crystalline outcomes can be small. To complement a training set from the visual observation of 147 456 crystallization outcomes, a…
This work is devoted to the evaluation of a change in the barrier height in the case of an atom jump to the nearest vacancy site under strain and to obtaining the vacancy diffusion equation taking into consideration the strain influence. Earlier, we suggested a new approach to solving the problem of the influence of e…
Abstract Core/shell nanowires of Al/Al 2 O 3 are obtained by decomposition of tert ‐butoxyalane on metal, silicon or glass substrates heated up to 650 °C without use of a noble metal seed. These biphasic nanowires are characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), scanning energy dispers…
Multistep colloidal chemical routes were employed to synthesize Pt/Au, Pt/iron oxide (IO), and Au/Pt/IO hybrid nanoparticles (NPs). The starting templates, Pt NPs, were synthesized by controlling the decomposition kinetics of platinum acetylacetonate in oleylamine. The morphologies of binary metal Pt/Au hybrid NPs wer…
We report the effects of partial substitution of Nb onto the V sites of ${\text{Fe}}_{2}\text{VAl}$ by measuring the electrical resistivity, Seebeck coefficient, and thermal conductivity as a function of temperature. It is found that the Nb substitution effectively produces a negative chemical pressure in the system.…
Lipid bilayer of 1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine (DMPE) was formed on the surface of a linearly growing polyanion/polycation polyelectrolyte multilayer (PEM) film prepared by the layer-by-layer (LbL) technique. The PEM films were prepared with two strong polyelectrolytes—poly(sodium 4-styrenesulfonate…
The structural evolution of a single-layer latex film during annealing was studied via grazing incidence ultrasmall-angle X-ray scattering (GIUSAXS) and atomic force microscopy (AFM). The latex particles were composed of a low-Tg (-54 degrees C) core (n-butylacrylate, 30 wt %) and a high-Tg (41 degrees C) shell (t-but…
The number and variety of macromolecular structures in complex with ;hetero' ligands is growing. The need for rapid delivery of correct geometric parameters for their refinement, which is often crucial for understanding the biological relevance of the structure, is growing correspondingly. The current standard for des…
Ab initio molecular orbital calculations were used to examine the adsorption of H 2 molecules on a Ti 2 −C 2 H 4 complex. Dependence of the adsorption energy on the computational method was elucidated, and the importance of Gibbs free energy correction on the adsorption energy was clarified. However, van der Waals int…
Abstract The mechanical properties and morphology of UHMWPE/PP(80/20) blend molded by injection and compression‐molding were investigated comparatively. The results showed that the injection‐molded part had obviously higher Young's modulus and yield strength, and much lower elongation at break and impact strength, tha…
Abstract Thiodiglycol (TDG) is a relatively nontoxic compound from organic wastes. By using TDG as a plasticizer with weights from 2.5 to 40%, we prepared soy protein isolate (SPI) films by a compression‐molding technique at 140°C and 15 MPa. The TDG‐plasticized films (SPI–TDG films) were characterized by scanning ele…
Nitric oxide is an important molecule in biology and modulates a variety of physiological and pathophysiological processes. Some of its regulatory functions are exerted through interactions with redox-active elements, including iron, nickel, cobalt, and sulfur. Metalloenzymes containing [ nFe- nS] ( n = 2 or 4) cluste…
We studied the transport of graphene electrons through lateral magnetic barriers. The relativistic electrons experience resonant tunneling through two adjacent but opposite magnetic field regions. For a periodic structure fabricated with such magnetic barriers, the resonant tunneling peak further splits into several s…
Abstract The focus of this article of a three part series is the effects of preparation and composition on the shear rheology of cellulose in the ionic liquid 1‐butyl‐3‐methylimidazolium chloride ([Bmim]Cl). Included are the effects of three different degrees of polymerization, (i.e., average molecular weight), manual…
A high quality Ca(5)(BO(3))(3)F (CBF) crystal, grown by flux method, was investigated for its non linear optical properties. This material is non hygroscopic and possesses a moderate birefringence suitable for UV light generation. On the basis of its refractive index dispersion curves, it is inferred that CBF has grea…
Synthesis and structural, magnetic and electrochemical characterization of the Ni(hfac) 2(pyDTDA) and the Fe(hfac) 2(pyDTDA) complexes are reported (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonato-; pyDTDA = 4-(2'-pyridyl)-1,2,3,5-dithiadiazolyl). Unlike the previously reported Mn(II) and Cu(II) complexes, but similar to…
Abstract The direct utilization of ethanol was investigated in CuCeO 2 , CuZr 0.35 Ce 0.65 O 2 (ZDC) and Cu/RuZr 0.35 Ce 0.65 O 2 anodes for solid oxide fuel cells (SOFC). The anodes were prepared by impregnation with nitrate precursors on a porous layer of yttria‐stabilized zirconia (YSZ) obtained by tape casting,…
Abstract DSC and time‐resolved WAXS and SAXS are used to study the structure development during isothermal crystallization of poly(glycolic acid) (PGA) in the temperature range 180–195°C. It is shown that the crystallization rate increases with degree of supercooling in the temperature range of consideration. WAXS and…
