Recent advances in the molecular dynamics simulations of spontaneous nucleation and growth methane hydrate show that an amorphous phase is first reached. However, has not been well described, due to insufficient identification cage structures. Here, we develop a method, called "face-saturated incomplete analysis", which can identify all face-saturated cages given system. As result, it found thousands types abundant occupancy states are present hydrate. Moreover, crystallinity evaluated...
Polydopamine (PDA)-based surface modification has been used in a variety of fields. However, vague impression on the stability PDA still exists due to lack systematic studies. To ascertain issue and make better use this method, technique plasmon resonance imaging (SPRi) was exploited study coated gold surface. The results showed that PDA-coating largely dependent pH aqueous solutions, giving detachment ratios up 66% 80% at 1.0 14.0, respectively. increasing ionic strength solutions could...
Molecular dynamics simulations were used to investigate the effects of external surface a 2:1 clay mineral with different charge amounts and locations on CH4 hydrate formation. The results showed that 512, 51262, 51263, 51264 formed away from surface. high- low-charge layers was occupied by Na+ form various distributions outer- inner-sphere hydration structures, respectively. adsorbed high-charge layer reduced H2O activity disturbing hydrogen bond network, resulting in low tetrahedral...
With an exception for its critical nucleus size, the more thermostat and barostat are used, faster methane hydrate nucleates lower crystallinity is.
A stepwise strategy was proposed to controllably amplify surface plasmon resonance imaging (SPRi) signals and used establish a method for sensitive detection of small saccharides large glycoconjugates. The key is enlarge the target analytes step by through cyclic recognition reaction concanavalin (ConA) with dextran, which can easily be integrated into SPRi detection. theoretically expected proceed infinite cycles addition ConA dextran one after another, in practice, it allows performing...
Carbon dioxide hydrate has been intensively investigated in recent years because of its potential use as gas and heat storage materials. To understand the formation mechanisms, crystallization CO2 from NaCl solutions was simulated at a molecular level. The influence temperature, pressure, salt concentration on evaluated. Results showed that amount newly formed cages pressure went through fast linear growth period followed by relatively stable period. Pressure had little effect temperature...
A criterion is proposed to judge which guest can enter the cage through face.
A surface plasmon resonance imaging method to differentiate the interaction between protein human high mobility group box 1 or nuclear positive cofactor 4 (PC4) and DNAs has been developed.
The formation and dissociation of gas hydrate can be promoted by different electrostatic field intensity, so it is considered as one the potential technologies with great application value in exploitation, prevention oil wells pipelines, hydrate-related technologies. Generally, these are used environment ionic solution, resulting phenomenon ion electrophoresis. physical-chemical interaction between ions electrophoretic migration inevitable, but this remains unclear. Herein, crystal structure...
