Among electrochemical energy storage (EES) technologies, rechargeable batteries (RBs) and supercapacitors (SCs) are the two most desired candidates for powering a range of electrical electronic devices. The RB operates on Faradaic processes, whereas underlying mechanisms SCs vary, as non-Faradaic in double-layer capacitors (EDLCs), at surface electrodes pseudo-capacitors (PCs), combination both hybrid (HSCs). EDLCs offer high power density but low density. HSCs take advantage process without...

Electrochemical impedance spectroscopy (EIS) is one of the most important tools to elucidate charge transfer and transport processes in various electrochemical systems including dye-sensitized solar cells (DSSCs). Even though there are many books reports on EIS, it often very difficult explain EIS spectra DSSCs. Understanding through calculating spreadsheet can be a powerful approach as user, without having any programming knowledge, go each step calculation get instant feedback by...

Abstract A selective and very simple electrochemical method, based on anodization of a glassy carbon electrode (GCE), was developed for the simultaneous detection hydroquinone (HQ) catechol (CT). It found that activated GCE showed an excellent catalytic behavior enhanced reversibility towards oxidation both HQ CT. The redox responses from mixture CT were easily resolved at GCE. limits calculated to be 0.16 0.11 μM, respectively. successfully examined real sample analysis with tap water it...

Stretchable organic light-emitting diodes are ubiquitous in the rapidly developing wearable display technology. However, low efficiency and poor mechanical stability inhibit their commercial applications owing to restrictions generated by strain. Here, we demonstrate exceptional performance of a transparent (molybdenum-trioxide/gold/molybdenum-trioxide) electrode for buckled, twistable, geometrically stretchable under 2-dimensional random area strain with invariant color coordinates. The...

A novel electrochemical sensor was fabricated by simply screen printing reduced graphene oxide (rGO) paste on F-doped tin (FTO) (rGO-SP-FTO) followed sintering at 450°C in Argon and employed for detecting dopamine (DA) uric acid (UA) simultaneously. The rGO film characterized using Raman spectroscopy, field emission scanning electron microscope (FE-SEM), Fourier transform infrared spectroscopy (FTIR). surface sensing features of rGO-SP-FTO were studied with impedance (EIS) cyclic voltammetry...

The demand for high-capacity energy storage along with high power output and faster charging has made supercapacitors a key area of research. charge capacity capacitors is largely dependent on the electrode materials utilized. To that end, graphene oxide (GO) reduced GO (RGO) have been extensively employed preparing supercapacitors. However, to date, no study reported utilizing GO/RGO bilayer material supercapacitor application. Herein, we report synthesis electrodes fluorine-doped tin (FTO)...

The cuprate superconductors are among the most widely studied quantum materials, yet there remain fundamental open questions regarding their electronic properties and role of structural degrees freedom. Recent neutron x-ray scattering measurements uncovered exponential scaling with temperature strength orthorhombic fluctuations in tetragonal phase $La_{2-x}Sr_xCuO_4$ $Tl_2Ba_2CuO_{6+y}$, unusual behavior that closely resembles prior results for emergence superconducting fluctuations, points...

Three electrode structures with different spatial arrangements of carbon nanotubes (CNTs) in the mesoporous TiO(2) layer were employed dye-sensitized solar cells to study effect surface states at interface formed by incorporation CNTs. It was found that decay open circuit voltage (V(oc)) significantly minimized avoiding direct contact conducting substrate introducing a thin buffer while maintaining superior electron collection efficiency from nanotubes.
