Monovalent - divalent cation competition at the muscovite mica surface: Experiment and theory [PDF]

, 2020
Hypothesis Ion adsorption on mineral surfaces depends on several factors, such as the mineral surface structure and the valency, size and hydration of the ion. In order to understand competitive adsorption at mineral surfaces, experimental techniques are

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

Advanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Divalent cation transport in isolated tubules

Kidney International, 1982
Since Burg introduced the technique of microperfusion of isolated renal tubules in 1966 [1], a number of papers has been published on sodium and water transport in various segments of the nephron. However, it was not until 1977 that transport of divalent ions was described using this technique [2].

Clustering of divalent cation-vacancy pairs in alkali halide crystals

, 1980
L'analyse par Unger et Perlman des résultats expérimentaux concernant la formation d'agrégats de paires bivalentes cation-lacune s'est révélée insuffisante pour distinguer entre la formation de dimères et le modèle de Dryden pour la formation de trimères,

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

Advanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Divalent Cation Requirements for Leukocyte Adhesiveness

Experimental Biology and Medicine, 1969
SummaryUsing a chelating agent which binds calcium ions 100,000-fold more avidly than magnesium ions (EGTA) it was demonstrated that PMN adhesion to glass or to other leukocytes was not a calcium-dependent process and that a slight excess of magnesium ion actually caused increased PMN adhesiveness in the virtual absence of calcium.

Nanomaterials for Allergy Diagnosis and Treatment: Advances, Opportunities and Translational Challenges

Advanced Science, EarlyView.
Nanomaterials offer dual applications in allergy management. For diagnosis, nanomaterials enhance analytical sensitivity and improve detection in specific IgE and functional assays such as the basophil activation test (BAT). For allergen‐specific immunotherapy, nanomaterials enable allergen masking and controlled release, and effectively modulate the ...
