A series of bis(3,6-di-tert-butylcarbazol-9-ylphenyl)aniline end-capped oligoarylenes, BCPA-Ars, are synthesized by double palladium-catalyzed cross-coupling reactions. By using this bis(carbazol-9-yl)triphenylamine moiety as an end-cap, we are able to reduce the crystallization and retain the high-emission ability of…
A joint experimental and theoretical study is presented of two asymmetric squaraine dyes and their parent symmetric dyes. The definition of reliable essential-state models for asymmetric squaraines sheds light on the intriguing spectroscopic behavior of this class of molecules, showing inverted and normal solvatochrom…
Chitosan can favorably modulate plasma lipids, but the available data are not conclusive. We evaluated the effect of chitosan on plasma lipids and lipoproteins in 28 patients with plasma triglyceride levels >150 mg/dL (mean age: 63 ± 12 years), not taking other lipid-lowering agents. All patients received a chitosan d…
A series of heterografted polymers with a polymethacrylate backbone and varying composition of oligomeric 2-oxazoline side chains was synthesized by copolymerization of oligo(2-ethyl-2-oxazoline)methacrylate and oligo(2- n -nonyl-2-oxazoline)methacrylate (ONonOx) macromonomers using the reversible addition–fragmentati…
A dynamic membrane is defined as a cake layer which forms on a support material, for example, filter cloth or mesh when the liquid to be filtered includes suspended particles. Formation of an effective dynamic cake layer is highly related with the retention of particles on the support material surface. Therefore, supp…
We study superconducting phases in a quasi-two-dimensional multilayer system without local inversion symmetry. Broken local inversion symmetry induces layer-dependent Rashba-type spin-orbit couplings. We find that a complex-stripe phase, which is the intermediate phase between the Fulde-Ferrell (FF) phase and Larkin-O…
Based on an inverted bulk band order, antimony thin films presumably could become topological insulators if quantum confinement effect opens up a gap in the bulk bands. Coupling between topological surface states (TSS) from opposite surfaces, however, tends to degrade or even destroy their novel characters. Here the e…
Differing from cell voltage and line current, anode current signals can provide an insight into the localized anodic dynamic behavior in an operating Hall–Héroult reduction cell, and can be used as an alternative in-depth method to study the process in the hostile industrial potline environment. This work involves fur…
To be compatible with 3-D vertical crossbar arrays, a TiO2/HfO2bilayer resistive-switching memory (RRAM) cell sandwiched between Ni electrodes is developed. The proposed device has numerous highly desired features for the implementation of 3-D vertical RRAM, including: stable bipolar resistive switching; forming free;…
On the bright side: A solution-based strategy was developed for in situ synthesis and film deposition of Cu2ZnSnSe4 nanocrystal films (samples a-d). The obtained Cu2ZnSnSe4 nanocrystal films can be used as an effective counter-electrode (CE) material to replace Pt, and yield low-cost, high-efficiency dye-sensitized so…
Homogeneously mixed silica–alumina samples with various Si/Al ratios (Si/Al = 9/1, 7/3, 5/5, 3/7, and 1/9) were prepared and characterized by infrared spectroscopy. Pyridine, propene, and CO were used as probe molecules to detect Brønsted and Lewis acid sites. The homogeneity of Si and Al in mixed oxides was confirmed…
In this paper, we have demonstrated a hierarchical architecture assembly from Sn-filled CNTs, which was in situ deposited on Cu foils to form binder-free electrode by incorporating flame aerosol deposition (FAD) with chemical vapor deposition (CVD) processes. The reversible capacity of Sn-filled CNTs hierarchical arch…
Anionic–anionic (N–N, P–P, N–P, and C–S) mediated coupling can be introduced in the layered perovskite La 2 Ti 2 O 7 structure for visible light photocatalysis. The anionic–anionic codoped La 2 Ti 2 O 7 systems lower the band gap much more than their respective monodoping systems. Moreover, the electronic band positio…
Mesoporous MgTiO3 perovskite with a high porosity and interfacial properties were synthesized via a solvothermal reaction at 150 °C for 10 h using a graft copolymer, i.e., poly(vinyl chloride)-g-poly(oxyethylene methacrylate) (PVC-g-POEM) with a well-ordered micellar morphology as a structure-directing agent. A PVC-g-…
BACKGROUND: The standard treatment for patients with pemphigus vulgaris has long consisted of high-dose glucocorticoids. Studies regarding the use of methotrexate in pemphigus vulgaris date back to 1968, but few have quantitatively described a steroid-sparing effect conferred by methotrexate. OBJECTIVES: We sought to…
Cu2ZnGeS4 (CZGS) and Cu2ZnGeSe4 (CZGSe) single crystalline nanowire arrays have been prepared via a convenient one-step nanoconfined solvothermal approach. The porous anodic aluminum oxide was used as a morphology directing template by offering nanospace in the AAO pores for confined solvothermal reaction. The structu…
Solvent effects have a significant impact upon the optoelectronic properties of coumarin 343, which are mainly exploited in the solution phase for a diverse range of applications, including lasers and dye-sensitized solar cells. The influence of solvation on the structure–property relationships for coumarin 343 are an…
Intermediate amyloidogenic states along the amyloid β peptide (Aβ) aggregation pathway have been shown to be linked to neurotoxicity. To shed more light on the different structures that may arise during Aβ aggregation, we here investigate surfactant-induced Aβ aggregation. This process leads to co-aggregates featuring…
Mitigation of type-I ELMs with n = 2 fields on JET with ITER-like wall, Liang, Y., Lomas, P., Nunes, I., Gryaznevich, M., Beurskens, M.N.A., Brezinsek, S., Coenen, J.W., Denner, P., Eich, Th., Frassinetti, L., Gerasimov, S., Harting, D., Jachmich, S., Meigs, A., Pearson, J., Rack, M., Saarelma, S., Sieglin, B., Yang,…
The zymogen prothrombin is composed of fragment 1 containing a Gla domain and kringle-1, fragment 2 containing kringle-2, and a protease domain containing A and B chains. The prothrombinase complex assembled on the surface of platelets converts prothrombin to thrombin by cleaving at Arg-271 and Arg-320. The three-dime…
