POTASSIUM ABSORPTION AND PARTITIONING IN COTTON AS AFFECTED BY PERIODS OF POTASSIUM-DEFICIENCY [PDF]
, 1991 Cotton (Gossypium hirsutum var. Latifolium) was grown in nutrient media, at two K levels: 58.5 mg/K and 11.7 mg/K. Potassium deficiency (11.7 mg K/g of K) was imposed upon cotton plants at different stages of plant development.

Diagnosing potassium deficiency by soil analysis
California Agriculture, 1973 Soil analysis, especially nitric acid extraction of potassium appears to be a very useful means of diagnosing potassium-deficient soils in California. Studies reported here compared two analytical methods for determining soil potassium levels.

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Pleiotropic effects of potassium deficiency in a heterocystous, nitrogen-fixing cyanobacterium, Anabaena torulosa [PDF]
, 1998 Omission of potassium from the growth medium caused multiple metabolic impairments and resulted in cessation of growth of the filamentous, heterocystous, nitrogen-fixing cyanobacterium Anahaena torulosa, during both diazotrophic and nitrogen-supplemented

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors
Advanced Materials, EarlyView.A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

The sodium-potassium pump controls the intrinsic firing of the cerebellar Purkinje neuron [PDF]
, 2012 In vitro, cerebellar Purkinje cells can intrinsically fire action potentials in a repeating trimodal or bimodal pattern. The trimodal pattern consists of tonic spiking, bursting, and quiescence.

The ionic balance of the sugar-beet plant [PDF]
, 1975 The ionic balance of the sugar-beet plant was studied by measuring dry weight and chemical composition of every leaf, the crown and the root during the growing season.The sugar-beet plant has an almost neutral uptake.
