In several countries, building-integrated photovoltaics (PV) solutions could contribute to the growth of total installed PV capacity. However, in some circumstances, relative high weight (10-15 kg/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) and lack aesthetics may constitute a barrier its diffusion. this work, we propose glass-free lightweight solution (≃6 compliant with hail mechanical load tests as prescribed by IEC...
Abstract In several countries, building‐integrated photovoltaics solutions could prospectively contribute to the growth of total installed photovoltaic (PV) capacity as they enable electricity production with minimal impact on free land. However, in some circumstances, relatively high weight (≥15 kg/m 2 ) existing glass/glass modules may constitute a barrier diffusion PV built environment. With aim limiting while preserving excellent mechanical stability and durability properties, we propose...
Self-assembled monolayers (SAMs) of 11-amino-1-undecanethiol (AUT) have been prepared on polycrystalline Au by immersion the corresponding surfaces in an AUT 1 mM solution pure ethanol. The films were studied cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), atomic force microscopy (AFM), and quartz crystal microbalance (QCM). Results CV EIS experiments NaClO4 agree with fast formation a well-packed film low current density (hundreds nA/cm2) capacitance values around 2...
The effect of electrolyte type and concentration on the differential capacitance 1,2-dichloroethane/water interface has been measured. results show that is controlled by pair ion (1)–counter-ion (2), where 1 2 denote different phases. At constant organic composition capacity increases in order, F– <SO2–4 < HO– ClO–4, Li+ <H+ <K+ <Mg2+ Ba2+ Sr2+≈ Ca2+. By contrast, at positive potentials aqueous composition, decreases TPA+ > MTMA+ TBA+ TOA+, TPB– TCPB–. In very dilute solutions, effects are...
Abstract Effect of in situ complexation some ions with variable valencies, like Co(II), Ni(II), Mn(II), Cu(II) and Pb(II) on the electrooxidation Vitamin C ( L ‐ascorbic acid) was studied by cyclic voltammetry using carbon paste electrodes modified p ‐tert‐butylcalix[4]arene ‐tert‐butylcalix[6]arene perchloric acid, acetic acid ammonium acetate media. found to bind strongly medium, resulting its being retained at electrode surface catalyzing oxidation ascorbic acid. The overpotential reduced...
The behaviour of several high Miller index crystal surfaces gold is examined by cyclic voltammetry in 0.01 mol dm–3 perchloric acid solutions. potentials zero charge, Eσ= 0, and their temperature coefficients, dEσ= 0/dT for the stepped faces (332), (771), (320) (410) are determined from a single minimum differential capacity curves. results compared with those existing other low-index order to establish relevance crystallographic structure double layer parameters. influence step density...
The effect of the solution pH and electrolyte anion on capacitive behavior observed for a self-assembled monolayer (SAM) ionizable 11-amino-1-undecanethiol (AUT) deposited polycrystalline Au was checked by cyclic voltammetry (CV) electrochemical impedance spectroscopy (EIS) using pure solutions. double layer capacitance (Cdl) decreased with increasing shown to be dependent anion, suggesting that equilibria controlling degree charge at may affect order thiol chains outermost part film. these...
Attracted to gold: The adsorption and assembly of nucleobases on gold electrodes, as well the influence surface atomic structure these electrodes adsorbed films, were studied by means cyclic voltametry (see picture) differential capacitance measurements.
Most of the existing solutions for Building Integrated PV (BIPV) are based on conventional crystalline-Silicon (c-Si) module architectures (glass-glass or glass-backsheet) exhibiting a relatively high weight (12-20 kg/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ). We working development robust and reliable lightweight with target 6 kg/m2. Using composite sandwich architecture thermal conductivity materials, we show that it is...
Conventional Silver/Silver-Chloride electrodes are inappropriate for routine high-density EEG and emerging new fields of application like brain computer interfaces. A novel multipin electrode design is proposed. It enables rapid easy while maintaining signal quality patient comfort. The described impedance tests performed with Titanium Nitride coated electrodes. results compared to conventional reference in a multi-volunteer study. calculated parameters prove the concept reproducibly acquire...
