Uses of nitrate ion sensitive electrodes

Eclética Química, 2018
Some models of ion-selective electrodes (ISE) and other methods have been elaborated, to quantify nitrate levels in environmental samples (water, fruits, vegetables and others), using direct ...

Thermodynamic Solution Properties of a Biodegradable Chelant (L-glutamic-N,N-diacetic Acid, L-GLDA) and Its Sequestering Ability toward Cd²⁺

Molecules, 2021
The thermodynamics of the interaction of L-glutamic-N,N-diacetic acid (GLDA) with protons was studied potentiometrically at different temperatures, ionic strengths and ionic media. Four protonation constants and corresponding enthalpy changes occurred at

Electrochemical analysis of antioxidant status of biological media in different sampling and storage conditions [PDF]

Journal of the Serbian Chemical Society
The use of an electrochemical approach for assessment of the oxidative stress severity is a promising direction for point-of-care testing development, which is especially important for critically ill patients.

Slowing Down Zinc Electrodeposition Kinetics Can Maximize and Compromise Anode Stability: How Slow Is Too Slow?

Angewandte Chemie, EarlyView.
Zinc anode performance is maximized within an optimal deposition‐kinetic window. Additives that tune the deposition exchange current density (i0,Dep) suppress HER at intermediate values, but overly fast kinetics promote dendrites and overly slow kinetics accelerate corrosion/HER.

Nanoscale electron transport at the surface of a topological insulator

Nature Communications, 2016
Topological insulators offer lossless surface transport because of the suppression of conduction-electron backscattering from defect sites. Here, the authors show that the nanoscale voltage drops caused by such scattering can be directly measured using ...

Modelling and optimization of surfactant sensor response characteristics for the use in surface water and wastewater analysis

Zaštita Materijala, 2014
The theoretical model of potentiometric titration curves of sodium dodecyl sulfate (anionic surfactant) was proposed and the response parameters of two surfactant sensors (commercial and self-made) were investigated.

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.
