Enhancement of technofunctional properties of chickpea flour through composite blending with teff and proso millet

Food Biomacromolecules, EarlyView.
Abstract The increasing demand for nutritionally rich and gluten‐free foods has intensified research interest in underutilized cereals and legumes as an alternative to conventional wheat‐based flours. The study aims to investigate the potential of developing composite flours from proso millet (Panicum miliaceum), teff (Eragrostis tef), and chickpea ...

New composite fibres for natural and waste waters decontamination from cesium radionuclides

Ядерна фізика та енергетика, 2017
New composite adsorbent based on modified polyacrylonitrile fibers is synthesized by in situ deposition of potassium-nickel ferrocyanide layer on the fibers’ surface. It is shown that the ferrocyanide phase forms a compact homogeneous layer on the fibers’

Sequential Injection Analysis of Cholesterol Using an Oxidation–Reduction Electrode Detector

Sensors
A new automated method for the determination of cholesterol in serum was developed by combining sequential injection analysis (SIA) with potentiometric detection using a gold oxidation–reduction potential (ORP) electrode because serum cholesterol is an ...

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

POTENTIOMETRIC TITRATION OF SODIUM AND POTASSIUM FERROCYANIDE [PDF]

Bulletin of the Chemical Society of Japan, 1932
Abstract (1) The potentiometric titrations of potassium and sodium ferrocyanide with mercuric chloride, nickel sulphate and cobaltous sulphate by using platinum electrode as an indicator electrode were studied at 25°C. (2) From the above titration we found that the reactions take place as follows.

Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

Journal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Determination of a Dimensionless Fluctuation Coefficient Using Electrochemical Impedance Spectroscopy

International Journal of Electrochemical Science, 2019
Using the Randles circuit model, we determined that, for the impedance to fall on a straight line in a Cole-Cole plot, a dimensionless fluctuation coefficient that represents the quantity of the fluctuation in ion concentration near an electrode must be ...

Subcellular Localization of Iron in Rhizophora mangle Leaves Revealed by Integrated Perls Reaction, TEM, STEM‐HAADF, and EDS Analyses

Microscopy Research and Technique, EarlyView.
Perls–TEM–STEM‐HAADF–EDS enables high‐resolution localization and elemental characterization of Fe‐containing deposits in Rhizophora mangle leaf cells. ABSTRACT Mangrove ecosystems are frequently exposed to high concentrations of iron (Fe) in sediments, resulting in Fe accumulation in plant tissues. Although Fe is an essential micronutrient involved in
