Magnesium also acts as a cofactor in many enzymes and ribozymes involved in the cleavage of phosphate esters and the transfer of phosphate groups (Yang et al., 2004). Though expression has been carried out without the addition of exogenous magnesium (Ryabova et al., 1995), a more recent ...
Two surface soils (Patua and Tokomaru) of contrasting mineralogy were incubated with several levels of either CaCO 3 or HC1. The effects of ionic strength on pH, on surface charge, and on the adsorption of phosphate and sulphate were measured in three concentrations of NaCl. The pH at which...

phosphate tetrahydrate (HUP) HUO2PO4·4H2O–usable above 1 °C—with an ionic conductivity of σ = 4 × 10−3 Ω−1 cm−1 at 20 °C and hydrogen uranyl arsenate tetrahydrate HUO2AsO4·4H2O—usable above 29 °C—with an ionic conductivity of σ = 6 × 10−3 Ω−1 40 ...
Instead, the collective effect of DNA charges drives larger Na+ association. To gain additional microscopic insights into the mechanisms of specificity on ionic associations in these systems, we carried out energetic analysis of the association between Na+ and K+ with chloride and dimethylphosphate ...

using the ÄKTA Pure system (GE Healthcare) with a 5 mL HisTrap column (GE Healthcare) according to the manufacturer’s instructions with an imidazole elution gradient using lysis buffer supplemented with 500 mM imidazole. Samples were dialysed against 50 mM sodium phosphate buffer to ...
Transient electron density maps of potassium dihydrogen phosphate (KH2PO4, KDP) are derived from femtosecond X-ray powder diffraction patterns. Upon photoexcitation, the low-frequency TO soft mode is elongated impulsively and modulates the electronic charge distribution on the length scale of interatomic...
Electrostatic modulation of nanochannel conductivity is not restricted to gating by protons. In principle, any process able to modify the charge on the walls of the channel can be used for gating, for example electrostatic gating was achieved in phosphate-modified pores by Ca2+addition[46,47]and...
