To develop an antimicrobial membrane for wound healing, the blended k‐carrageenan (KC)/carboxymethyl chitosan (CMCH) membranes were fabricated through a freeze‐drying process together with a dual‐ion (Cu2+and K+ or Cu2+and Ca2+) crosslinking approach. The dual‐ion crosslinking by Cu2+...
S K-edge XAS and DFT calculations on cytochrome P450: covalent and ionic contributions to the cysteine-Fe bond and their contribution to reactivity. E.I.: S K-edge XAS and DFT calculations on cytochrome P450: covalent and ionic contributions to the cysteine-Fe bond and their contribution to ...
K+can exhibit considerably weaker Lewis acidity and smaller Stokes radius in organic solvents compared with Li+and Na+[15]. Hence, K+demonstrates a low desolvation energy and high ionic conductivity, which are beneficial for

(LiCl and CsCl) and ammonium ions (NH4+) in external buffer, minimal changes in internal pH were observed (Fig.2c). In addition, lucigenin assay suggested thatMG/h-TELOcould not transport Cl−-ions (Supplementary Fig.9). Furthermore, when 100 mM KCl was present in internal solution...

Experimental validation. Our computational analysis identified K101-E107 and E107- K101, among others (Figs 4 and S5), as key inter-monomer salt bridges that stabilize the largely polar interface of an i1-mediated dimer. We disrupted these ionic interactions by replacing one of the ...
Regarding the Zn-P bonds, the polar covalent bonds between Zn and P atoms were due to the transfer charges shifted toward P atoms. Figure 1. (a) The lowest-energy geometry of the ZnSiP2 monolayer, with top and side views.(b) The charge density difference of the ZnSiP2 monolayer. (...
Ionic (covalent) bonding is present when the Cauchy pressure has a positive (negative) magnitude. The negative Cauchy pressure was used to create the covalent bonding. Debye temperature (θD) [43] and melting point (Tm) were two more thermodynamic variables that were investigated and expressed ...
