Stretching exercises: The electrochemical behavior of pseudomorphic palladium monolayers (PdML) on various single-crystal electrodes is investigated (see picture) to demonstrate the influence lateral compression and dilation surface activity. adsorption catalytic activity for formic acid electrooxidation varies dramatically depending whether monolayer compressed or dilated by electrode.
Lead-borate glasses reinforced by Er3+ and Nd3+ ions with the form 50B2O3–30CaO–20PbO-0.5Er2O3-x (Nd2O3), where x = 0–1.50 mol% labelled as S1–S7 were fabricated utilizing traditional melt quenching technique. Physical, structure, ultrasonic mechanical, dielectric properties of proposed investigated. The density glass system showed a decrement from 3757 to 3646 kg/m3. molar volume increased 2.566 × 10−5 m3 for sample S1 2.831 S7. Introduction induced amplified changes in local field on lead...
Mg–Ca alloys have recently attracted great attention towards the research in field of orthopedic biodegradable implants. This study presents an vitro degradation assessment Mg–0.8Ca (0.8 wt. % Ca) alloy Hank's balanced salt solution (HBSS). Immersion, hydrogen evolution and electrochemical behavior was studied as well cytotoxicity products. Morphology phase composition corrosion products were using SEM, EDX XRD techniques. Degradation HBSS resulted formation needle-shaped carbonated...
Transition metal chalcogenides (TMCs) with high theoretical capacity are regarded as promising anodes for sodium-ion batteries (SIBs) but encounter several challenges because of the complex conversion process, which leads to...
SrO-Bi2O3- B2O3 glass systems with different content of neodymium oxide Nd2O3 were prepared by rapid-quenching technique. On Record FTIR deconvoluted spectra in the range 400–2000 cm-1. Some parameters such as; density and molar volume acquired. Ultrasonic wave velocities (longitudinal shear) elastic moduli The results interpreted as due to role Nd2O3. Formation BO4 causes an increase rigidity glass, consequently resulted density. Increment revealed that addition extension network. presence...
In the present study, sawdust/recycled expanded polystyrene (SD/rEPS) composite was manufactured to be used as sound-absorbing materials. To achieve this aim, SD/rEPS composites containing different loading level (0, 20, 40, 60 and 80 wt percent) of SD were prepared. The addition 20% exhibited better dispersion within recycled (rEPS) matrix than higher SD, indicated from scanning electron microscope. Consequently, tensile strength flexural improved by 16.7% 14.1%, respectively. displayed...
Abstract Transition metal sulfides are emerging as promising anode materials for sodium‐ion batteries (SIBs) due to their high theoretical capacity and low cost, practical application yet face critical issues of sluggish kinetics poor cycling stability. In this study, a reliable approach is introduced overcome these challenges by fabrication Se 0.75 ‐Fe 1‐x S 0.25 @SC hollow nanospheres thanks the enriched robust Fe─S─C, C─S, C─Se bonding, which greatly benefit enhancing both reaction...
Dehnungsübungen: Das elektrochemische Verhalten von pseudomorphen Palladium-Monoschichten auf einkristallinen Substraten wurde untersucht, um den Einfluss lateraler Deformation die Oberflächenreaktivität aufzuzeigen. Völlig unterschiedliche katalytische Aktivitäten wurden für Elektro-Oxidation Ameisensäure gemessen, je nachdem ob Palladium-Monoschicht durch das Substrat komprimiert oder gedehnt war (siehe Bild).
The electrochemical behavior of a PtRu(111) single crystal with 1:1 bulk atomic ratio is investigated for the first time by means cyclic voltammetry and scanning tunneling microscopy (STM). electrode surfaces are enriched either Ru or Pt, depending on cooling conditions after inductive heating. Analysis STM shows typical topography smooth terraces separated monoatomic high steps. voltammetric characterization in acid media clearly reveals an altered Pt compared to Pt(111) Ru(0001),...
