Spin diffusion transfer difference (SDTD) NMR: An advanced method for the characterisation of water structuration within particle networks
نویسندگان
چکیده
The classical STD NMR protocol to monitor solvent interactions in gels is strongly dependent on gelator and concentrations does not report the degree of structuration at particle/solvent interface. We hypothesised that, for suspensions large particles, could be characterised by when taking into account particle-to-solvent 1 H– H spin diffusion transfer using 1D equation. have carried out a systematic study effect concentrations, surface charge, affecting behaviour build-up curves. To do so, we dispersions starch cellulose-like particles prepared deuterated water alcohol/D 2 O mixtures. Spin Diffusion Transfer Difference (SDTD) independent hence allowing estimation within different particle networks. In addition, simulation SDTD curves general one–dimensional equation allows determination minimum distances ( r ) rates D This novel can readily extended characterise solvent(s) organisation any type colloidal systems constituted particles.

An Implicit Difference-ADI Method for the Two-dimensional Space-time Fractional Diffusion Equation
Fractional order diffusion equations are generalizations of classical diffusion equations which are used to model in physics, finance, engineering, etc. In this paper we present an implicit difference approximation by using the alternating directions implicit (ADI) approach to solve the two-dimensional space-time fractional diffusion equation (2DSTFDE) on a finite domain. Consistency, unconditi...

On an explicit finite difference method for fractional diffusion equations
A numerical method to solve the fractional diffusion equation, which could also be easily extended to many other fractional dynamics equations, is considered. These fractional equations have been proposed in order to describe anomalous transport characterized by non-Markovian kinetics and the breakdown of Fick’s law. In this paper we combine the forward time centered space (FTCS) method, well k...
متن کاملEnergy transfer and the photon lifetime within an aerosol particle.
The theory of enhanced energy transfer within an aerosol particle based on donor coupling to morphological dependent resonances is tested for the first time to our knowledge. The correspondence between theory and experiment is good and allows one to obtain the photon lifetime within the longest-lived resonances. A comparison between this lifetime and the lifetime as obtained by Mie theory is di...
متن کاملNumerical study of water diffusion in biological tissues using an improved finite difference method.
An improved finite difference (FD) method has been developed in order to calculate the behaviour of the nuclear magnetic resonance signal variations caused by water diffusion in biological tissues more accurately and efficiently. The algorithm converts the conventional image-based finite difference method into a convenient matrix-based approach and includes a revised periodic boundary condition...
