The phosphorylated Stat1 preparations bound to various DNA recognition sites with the same Keq of approximately 1 x 10(-9) M; distinction between 'weak' and 'strong' binding sites is determined by the very rapid dissociation (< 30 s, t1/2) from 'weak' sites compared with 'strong' sites ...
45,46 Notably, the weak peak at 402.2 eV was associated with positively charged amine (C–NH3+) (Figure S2B).46,47 Furthermore, the N content of HPC–NH2 determined by XPS and EA were 2.68% and 0.57%, respectively (Table S2), which clearly indicated the successful grafting of –NH2 ...
either being held onto or released66,67. Adsorption equilibrium occurs when the amount of substance attached to the solid reaches a balance with the amount remaining in the solution. This equilibrium
It is noteworthy that strong dipolar truncations arising from labeled carbons separated by one or two bonds may also have resulted in the weak dipolar interactions [47]. Download: Download high-res image (275KB) Download: Download full-size image Fig. 9. 2D DNP enhanced 13C-13C DARR ...
Nanomaterials are one of the most reactive minerals that have high surface area, strong oxidizing/adsorptive abilities and good stability. Especially, the hollow structures at the nano scale are attracting fast growing interest because they can be used to find new applications owing to their specific...
Infrared data are given in cm'1(abbreviations: (vs) very strong, (s) strong, (m) medium, (w) weak), (vw) very weak. M ssbauer parametersare given in mms'1 (abbreviations: Q.S = quadrupole splitting, I.S = isomer shift, Γ = full width at half-height).RESULTS AND DISCUSSION:Le...
(-9) M; distinction between 'weak' and 'strong' binding sites is determined by the very rapid dissociation (<30 s, t(1/2)) from 'weak' sites compared with 'strong' sites (similar to 3 min, t(1/2)), Reports of 'weak' tandem binding sites in a natural gene caused us to ...
Their intrinsic frequency was estimated to be at 3682 cm(-1) and the lower values detected are due to a very weak H-bonding to the MOF walls. Both samples are practically dehydroxylated at 523 K but easily re-hydroxylated at ambient temperature in presence of water. Three probe molecules ...
The Er2O3 nanoparticles decorated as a shell with a more negative conduction band (CB) could provide strong reducing electrons and strengthen the stability. We found the existence of Er-BDC intermediate layer triggered the intimate contact between RE oxides and UiO-66-NH2, leading to the fast ...
The interactions between organic guests and inorganic hosts range from weak ones, such as hydrogen bonding and ion–dipole interactions, to strong ionic bonding. If layered inorganic compounds possess reactive groups on the interlayer surface, it is also possible to bind organic groups via covalent ...
