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].

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

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 ...

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.

Effect of Divalent Cations on RED Performance and Cation Exchange Membrane Selection to Enhance Power Densities [PDF]
, 2017 Reverse electrodialysis (RED) is a membrane-based renewable energy technology that can harvest energy from salinity gradients. The anticipated feed streams are natural river and seawater, both of which contain not only monovalent ions but also divalent ...

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...
