Melanie Meyer-Luehmann et al. recently reported that amyloid plaques form extremely rapidly-within one day, in three mouse models of Alzheimer’s disease studied longitudinally in vivo [1]. However, the ‘rapid appearance’ of ‘newborn’ amyloid plaques can also be the result of delayed visualization of existing amyloid plaques, which is caused by the increase in the concentration of methoxy-XO4, a...

Macromolecular crystallography suffers from two major issues: getting well-diffracting crystals and solving the phase problem inherent to large macromolecules. Here, we describe the first example of a lanthanide complex family named "crystallophore" (Xo4), which contributes to tackling both bottlenecks. This terbium complex, Tb-Xo4, is an appealing agent for biocrystallography, combining the ex...

Copper and copper oxides are well-known excellent catalysts in several chemical processes, but their low mechanical and electrochemical stability restrict their direct utilization as electrodes in electrolytic processes. In this work, the incorporation of copper into cobalt oxide (CuxCo3-xO4) is presented as an excellent approach to obtain highly active and robust copper-based electrocatalysts....

Multiferroic materials exhibit magnetoelectric (ME) coupling and promise new device applications including magnetic sensors, generators, and filters. An effective method for developing ME materials with enhanced ME effect is achieved by the coupling through the interfacial strain between piezoelectric and magnetostrictive materials. In this study, the electrical and magnetic properties of Ga do...

Yb and Er codoped NaT(XO4)2 (T = Y, La, Gd, Lu and X = Mo, W) disordered oxides show a green (Er3+ related) up-conversion (UC) efficiency comparable to that of Yb:Er:β-NaYF4 compound and unless 3 times larger UC ratiometric thermal sensitivity. The similar UC efficiency of Yb:Er doped NaT(XO4)2 and β-NaYF4 compounds allowed testing equal subcutaneous depths of ex-vivo chicken tissue in both cas...

The effectiveness of Mg as a promoter of Co-Ru/γ-Al2O3 Fischer-Tropsch catalysts depends on how and when the Mg is added. When the Mg is impregnated into the support before the Co and Ru addition, some Mg is incorporated into the support in the form of MgxAl2O3+x if the material is calcined at 550°C or 800°C after the impregnation, while the remainder is present as amorphous MgO/MgCO3 phases. A...

We present a new concept for homogeneous spinel nanocrystal-coating on high crystalline pristine-carbon nanotubes (CNTs) for efficient and durable oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Oxidized CNTs have widely been used to functionalize with metal or metal oxides since the defect sites act as anchoring for metal oxide binding. However, such defects on the tubes c...

We reviewed the synthesis, structure, and properties of pyridine complexes AgXO4 (X = Cl, Mn, Re) compounds with various compositions ([AgPy2] XO4, [AgPy2XO4]·0.5Py, [AgPy4] 4 [AgPy2XO4] XO4). also clarified controversial information about existence composition silver permanganate, used widely as mild selective oxidants in organic chemistry. discussed detail available structural spectroscopic (...

Bu çalışmada, sırasıyla DC magnetron ve RF püskürtme ile demir oksit bakır yapıları büyütülmüş CuxFe3-xO4 yapısı ise birlikte (Co-sputtering) büyütülmüştür. Büyütülmüş ince filmlerin yapısal optik topografik incelemeleri detaylı olarak yapılmıştır. İnce absorpsiyon ölçümleri, oda sıcaklığında Perkin Elmer UV/Visible Lambda 2S spektrometresi yardımıyla alınmıştır. Cam üzerine büyütülen Fe2O3, Cu...

LiMn2O4 spinel is an attractive compound as a cathode material in lithium-ion batteries, due to its economical, environment, and safety advantages over LiCoO2. LiMn2O4 adopts the spinel structure with the space group Fd3 hm, in which the Li and Mn occupy the 8a tetrahedral and 16d octahedral sites of the cubic close-packed oxygen ions framework, respectively. However, LiMn2O4 tends to exhibit c...
