Assessment of spatial variability of cation exchange capacity with kriging and cokriging [PDF]
Desert, 2019 Cation exchange capacity (CEC) is one of the most important soil attributes which control some basic properties of soil such as acidity, water and nutrient retaining capacity.

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride
Advanced Functional Materials, EarlyView.This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Advanced Functional Materials, EarlyView.Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Relevance of cation-exchange capacity of cell wall in detecting H+-symport in yeasts
, 1987 Addition of mono- or divalent cations to unbuffered yeast suspensions causes acidification of the medium. In some yeasts (Rhodotorula glutinis and Metschnikowia reukaufii) this represented a mediated H+ extrusion in exchange for cations (mostly K ...

Chemical attributes of a remineralized Oxisol
Ciência Rural, 2017 : Remineralizers are comminuted rocks that are applied to soil, and their use as an agricultural amendment was regulated in Brazil in 2013. However, mechanisms of action of these materials must be better known to enable them to be best used in ...
