The complexation of five recently synthesized hydroxy-thioxanthone derivatives with Al3+ ion was studied in a methanol solution spectrophotometrically, and the stepwise formation constants of the resulting 1:1 and 2:1 (ligand-to-metal) complexes were evaluated. The suitability of the thioxanthone derivatives as neutral ionophores for the preparation of a new Al3+ ion-selective PVC-membrane elec...

The possibility of using molten mixtures of 1,4-dimethyl-l,2,4-triazolium chloride (DMTC) and aluminum chloride (A1C13) as secondary battery electrolytes was studied, in some cases extended by the copresence of sodium chloride. DMTC-A1CI~ mixtures demonstrated high specific conductivity in a wide temperature range. The equimolar system is most conductive and has K values between 4.02 x 10 -~ an...

This paper reports the benefits of a carbon coated aluminum current collector specifically designed to promote LiNi1.5M1.5O4 (LNMO) as high potential positive electrode material. underlayer allows efficient protection surface in 1 M LiTFSI/[EC/DMC] electrolyte for more than 100 cycles (C/2 – D/2) experimental conditions mimicking electrochemical response LNMO. The design such coating appears th...

Characterization of molecular scale electronic devices generally involves deposition of a metal top electrode onto an organic film. During the evaporation process, high-energy granules of metals may lead to unwanted reactions between the organic molecules and deposited top electrodes. This can cause, as commonly reported, lasting damage which leaves most junctions either shorted or an open circ...

The role of isothermal aging on the localized corrosion behavior of Al90Fe5Gd5 and Al87Ni8.7Y4.3 alloys was characterized in 0.6 M NaCl solution. The pitting (Epit) and repassivation (Erp) potentials were both increased ~400 mV by the presence of transition and rare earth metal additions in supersaturated solid solution and amorphous structure. A statistical distribution in Epit observed on sma...

The fabrication and unique characteristics of a new type of thin layer electrode, an optically reflective thin layer electrode (ORTLE), are described. The electrode was fabricated by the anodization of a thin layer of aluminum sputtered onto a plain glass microscope slide to create a 750 nm-thick porous alumina film. A thin film of gold was then sputtered atop the porous and transparent alumina...

The dual corona electrode, consisting in an ionizing wire in parallel with a metallic cylindrical support, at same high voltage supply, has been extensively studied in relation with various electrostatic applications. In practical situations, the dual corona electrode may be installed in the proximity of metallic objects that will affect the electric field repartition and, hence, the developmen...

The Front Cover shows magnesium-doped MnO2 nanorods that are used as an electrode material capable of intercalating/de-intercalating aluminum ions. open tunnel structure the nanomaterial well presence dopant magnesium cations facilitates this process, opening up possibility using in aqueous Al-ion batteries or supercapatteries.

0 Fluoride contamination occurs in a wide range of industrial effluents-wastewater from aluminum and steel production, metal finishing and electroplating, glass and semiconductor manufacturing, ore-beneficiation, and fertilizer operations. Concentration limits for fluoride of 1.0 to 1.5 mg/L have been established from time to time for surface waters, based upon two premises: (1) that these wate...

Engineering materials that can store electrical energy in structural load paths revolutionize lightweight design across transport modes. Stiff and strong batteries use solid-state electrolytes resilient electrodes separators are generally lacking. Herein, a battery composite with unprecedented multifunctional performance is demonstrated, featuring an density of 24 Wh kg?1 elastic modulus 25 GPa...
