“…Both sugars showed high solubility for [EMIM] [EtSO 4 ] as compared to aliquat336 and aliquat [NO 3 ]. Liu et al [16] determined the solubility of glucose in IL + anti solvent mixtures at temperature of 0-60 C. [ Thus in order to study the solvation property, the solubility data of IL's in biomass components are a prerequisite for the design of separation and reaction units [18][19][20][21][22][23][24]. Further when ILs are used as solvents, there is also a possibility for its regeneration and reutilization which ultimately reduces the associated process cost [25].…”

“…It is known that the solubility of glucose is dependent on the intermolecular attractions between glucose-glucose and glucose-solvent molecules. Molecular dynamics simulations have shown that water acts as a solubility enhancer that increases the mobility and monodispersity of the system which leads to an increase in glucose solubility in ionic liquids with a consequent increase interaction between solute (glucose) and solvent (water) [29]. However, we do not know if the solvation shell of glucose or the dynamics of solutesolvent interactions may be responsible for the resistive effect observed empirically.…”

We investigated possible variations of impedance values in samples of sodium chloride solution (sodium chloride 0.9%) with glucose at different concentrations, ranging from 5000 to around 75 mg/dL. The sodium chloride solution (either saline physiological solution) was chosen since it has similarities to blood but no cell components, which may be confounding factors in this study. Special focus was on the effect of stirring and of temperature variations on the impedance spectrum of samples at different glucose concentrations. We found that variations in glucose concentration directly affect the impedance modulus of the sample both in static conditions and in dynamic conditions due to stirring, as well as at both room temperature and at increased temperature. In fact, even if the impedance variations were often small (around 3-4 mΩper mg/dL), they were usually clearly measurable. These findings may be the basis for possible development of a new approach, based on impedance technology, for the noninvasive monitoring of glycaemia.

“…The particle mesh Ewald (PME) summation method 46 was used to calculate the electrostatic potential under periodic boundary conditions in all directions. We successfully used similar protocols for MD simulations of various biomolecules, including ligand functionalized gold nanoparticles, 47 DNA−graphenebased surfaces, 48 solvent−solute complexes, 49 and ionic materials. 50 To refine the structure and dynamics of the three different systems in vacuum, we also employed MD simulations using AMBER 14.…”

Self-assembled monolayers (SAMs) have been widely used to engineer the electronic properties of substrate-supported graphene devices. However, little is known about how the surface chemistry of SAMs affects the interfacial mechanical properties of graphene supported on SAMs. Fluctuations and changes in these properties affect the stress transfer between substrate and the supported graphene and thus the performance of graphene-based devices. The changes in interfacial mechanical properties can be characterized by measuring the out-of-plane elastic properties. Combining contact resonance atomic force microcopy experiments with molecular dynamics simulations, we show that the head group chemistry of a SAM, which affects the interfacial interactions, can have a significant effect on the out-of-plane elastic modulus of the graphene-SAM heterostructure. Graphene supported on hydrophobic SAMs leads to heterostructures stiffer than those of graphene supported on hydrophilic SAMs, which is largely due to fewer water molecules present at the graphene-SAM interface. Our results provide an important, and often overlooked, insight into the mechanical properties of substrate-supported graphene electronics.
