THIOCYANATE ION-SELECTIVE PVC MEMBRANE ELECTRODE [PDF]

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2010
A potentiometric selective sensor based on trinuclear chromium(III) complex as a novel ionophore for the thiocyanateselective electrode is reported. The sensor displays a near Nernstian slope of 57 ± 2 mV per decade, over a wide pH range 3 - 11.

A computer‐controlled potentiometric/spectrophotometric titrator [PDF]

Journal of Analytical Methods in Chemistry, 1988
A laboratory computer controlled potentiometric titrator interfaced to a diode array spectrophotometer is described. The titrator consists of widely used, commercially available components; therefore, major attention is given to modes of interconnection and software implementation in data format and system control.

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

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.

Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

Sedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...

Effect of magnetic field on hydraulic conductivity and cation displacement in soil in the semi‐arid region of Brazil

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Population growth intensifies the production of waste from agricultural and industrial sources, among others, directly impacting soil and water resources. The use of techniques involving magnetic field applications has been investigated as a potential approach to improve soil–water interactions, although its effects are still not fully ...

Phenotypic, physicochemical, sensory, and functional attributes of cocoa (Theobroma cacao L.) from Brazilian Amazonian floodplain and upland ecosystems

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7775-7783, October 2026.
Abstract BACKGROUND Cocoa (Theobroma cacao L.) from the Brazilian Amazon plays an important role in national production. While most cocoa is cultivated in upland systems, floodplain ecosystems represent a traditional and distinct production environment that may influence bean composition and quality.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.
