The guidelines of Unified Facilities Criteria (UFC) and U. S. General Service Administration (GSA) provide the design requirements to reduce the potential of progressive collapse for structures. According to these codes, progressive collapses are occurred due to loss of a main vertical structural element. In this stud…
An ultra-high-resolution NMR experiment for the measurement of intraresidue (1)H(i)-(15)N(i)-(13)C'(i) dipolar-chemical shift anisotropy relaxation interference is employed to extract information about local backbone geometries in intrinsically disordered proteins. The study of tumor suppressor BASP1 revealed a popula…
Abstract Z‐contrast imaging in an aberration‐corrected scanning transmission electron microscope can be used to observe and quantify the sizes, shapes, and compositions of the metal frames in supported mono‐, bi‐, and multimetallic metal clusters and can even detect the metal atoms in single‐metal‐atom complexes, as w…
Abstract Cucurbit[n]uril‐based rotaxane or pseudorotaxane devices connected to gold electrode surfaces and spherical gold nanoparticles have previously been developed. Herein, we report the preparation and characterization of gold nanorods (GNRs) protected by a hydrophilic cucurbit[7]uril‐based‐pseudorotaxane anchored…
Abstract This paper reports the results of an experimental investigation of blast furnace slag paste activated by potassium hydroxide and sodium silicate. Reasonable workability and setting times were maintained. The workability was measured in terms of flow diameter. The loss of flow with time was also studied. The m…
OBJECTIVE: Bilateral internal mammary arteries (BIMA) remain widely underused in coronary artery bypass grafting (CABG). In this study, we aim to investigate the early and long-term outcomes of BIMA grafts in isolated CABGs. DESIGN: Single-centre retrospective observational study. SETTING: University Hospital, Nancy.…
Abstract An efficient method was investigated for the synthesis of 3‐pentadecylphenyl acrylate (PDPA) via one‐pot reaction of esterification in the presence of an ionic liquid as catalyst. In order to understand the esterification reaction process, a mathematical relationship between the yield of esterification and th…
Platinized counter electrode is common in most of the dye sensitized solar cell (DSSC) researches because of its high catalytic activity and corrosion stability against iodine in the electrolyte. Platinum (Pt) film coating on fluorine doped tin oxide (FTO) glass surface by using alcoholic solution of hexachloroplatini…
The fabrication of modern microelectronic silicon devices mechanically challenges these thin silicon substrates during manufacturing operations. Melt and solution polyesterification enabled the synthesis of polyesters containing photoreactive o-nitro benzyl ester units for use as a potential photocleavable adhesive. M…
Abstract Helical inclusion complexes of amylose with fatty acids can form spherulites of various morphological types. Previous studies have described the spherulites obtained by cooling dispersions of steam jet cooked corn starch either by itself or supplemented with various fatty acids. In light of potential advantag…
The unusual suspects: Depending on co-ligands L(n) and the effects of substituents (R), the well-known triazenides [N(NR)2](-) may act as EPR detectable coordinated triazenyl ligands, [N(NR)2](·). They are thus new non-innocent ligands and are related to the hitherto unused non-innocent nitrogen dioxide ligand, [NO2](…
Abstract As‐received poly(ethylene terephthalate) (asr‐PET) may be reorganized by precipitation from trifluoroacetic acid upon gradual addition to a large excess of rapidly stirred acetone (p‐PET). Unlike asr‐PET, p‐PET repeatedly crystallizes rapidly from the melt, and can be used in small quantities (a few %) as an…
Planar electromagnetic sources characterized by a periodic variation of their beam coherence–polarization matrix are investigated, as far as the polarization features of the radiated fields are concerned, within the framework of the paraxial approximation. A propagation scheme based on plane-wave decomposition leads t…
In this paper, we consider the forward problem in depolarization by optical systems. That is, we seek a compact parameterization that allows us to take an arbitrary "pure" optical system (namely one defined by a single Mueller-Jones matrix) and model all possible ways in which that system can depolarize light. We mode…
A manganese oxide-based, thermochemical cycle for water splitting below 1000 °C has recently been reported. The cycle involves the shuttling of Na + into and out of manganese oxides via the consumption and formation of sodium carbonate, respectively. Here, we explore the combinations of three spinel metal oxides and t…
Abstract Ionic liquids (ILs) have been investigated for their potential as reagents for enhancing the fire resistance of wood. The following ILs were in focus: 1-ethyl-3-methylimidazolium bromide, 1-ethyl-3-methylimidazolium tetrafluoroborate, and 1-ethyl-3-methylimidazolium hexafluorophosphate ([C2mim][PF6]). Suppose…
Aiming at the complexity of the structure in the end region of large turbogenerators, 3-D mathematical and physical models of nonlinear transient eddy current field are given by taking a 330-MW water-hydrogen-hydrogen-cooled turbogenerator for example. Both nonlinearity ofB-Hcurve and noncontact structure between the…
Aiming at the design of new luminescent host-guest materials with minimized aggregation effects, two classes of sol-gel derived mesoporous materials were explored as hosts for Rhodamine 6G (Rh6G) dye: The first consists of pure (SiO2) and phenyl-modified silica (Ph0.17SiO1.915) xerogels, prepared via sol-gel reaction…
InGaN/GaN light-emitting diodes (LEDs) with a graded-composition multiple quantum well (GQW) were designed not only to investigate the effect of polarization field on the efficiency droop in InGaN/GaN multiple quantum wells (MQWs) but to find out possible solutions to prevent or reduce the efficiency droop in GaN-base…
Small‐sized monodisperse Pd‐Ag alloy nanocrystals (NCs) are synthesized via a solid‐liquid and solid‐solid phase chemical route, i.e., sequential reduction of Pd(NO3)2 and AgNO3 solid precursors in the liquid mixture of dodecylamine and 1‐octadecene, followed by fusion of formed Pd and Ag NCs at 250 °C. By controlling…
