Although electrokinetic treatments for soil remediation and ground improvement have gradually undergone significant experimental development, one of the most important physical phenomena has received very little attention in recent years. Electroosmotic flow, especially unsaturated conditions, not been simulated domains more than dimension. In present work, a modification M4EKR code was used to...

Simultaneous analysis of ascorbic acid (AA), uric (UA), and dopamine (DA) is desirable as they are important biomarkers that coexist in biological fluids. Electrochemical detection these molecules can be challenging their oxidation peaks poorly resolved at most unmodified electrodes. Modifications typically necessary for which increase cost complicate fabrication. Herein, inexpensive moldable p...

The rational design of better electrocatalysts for the oxidation C1–C2 organic molecules requires detailed knowledge their mechanism. Pt single crystals are powerful tools to study, in a simple way, surface structure effect on different reaction pathways. Here, mechanism these is compared so that gained with simpler transferred analysis more complex ones. goal strategies platinum electrodes imp...

Polymeric membrane ion-selective electrodes (ISEs) have been widely applied in environmental analysis. In many cases of practical relevance, however, when these sensors are complex samples, they could suffer from problems biofouling (related to microorganisms and biofilms) which may shorten the sensors’ lifetimes cause measurement errors. Herein, we describe a robust effective method endow ISE ...

Applying an inverted voltage to the "sidekick" electrodes during ion cyclotron resonance detection improves both Fourier transform ion cyclotron resonance (FT-ICR) mass spectral signal-to-noise ratio (at fixed resolving power) and resolving power (at fixed signal-to-noise ratio). The time-domain signal duration increases by up to a factor of 2. The method has been applied to 7-T FT-ICR MS of el...

Double-docking self-assembled monolayers (DDSAMs), namely self-assembled monolayers (SAMs) formed by molecules possessing two docking groups, provide great flexibility to tune the work function of metal electrodes and the tunnelling barrier between metal electrodes and the SAMs, and thus offer promising applications in both organic and molecular electronics. Based on the dispersion-corrected de...

In order to obtain gold electrode surfaces modified with Human Papillomavirus L1 protein (HPV L1)-derived peptides, two sequences, SPINNTKPHEAR and YIK, were chosen. Both have been recognized by means of sera from patients infected with HPV. The molecules, Fc-Ahx-SPINNTKPHEAR, Ac-C-Ahx-(Fc)KSPINNTKPHEAR, Ac-C-Ahx-SPINNTKPHEAR(Fc)K, C-Ahx-SPINNTKPHEAR, and (YIK)₂-Ahx-C, were designed, synthesize...

Minimizing overpotential and generating high faradaic currents are critical issues for fast-scan voltammetry of beta-nicotinamide adenine dinucleotide (NADH) for the sensitivity of enzyme-modified electrodes based on dehydrogenases. Although NADH voltammetry exhibits high overpotential and poor voltammetric peak shape at solid electrode surfaces, modification of the electrode surface can improv...
