The virtual programming lab (VPL) project described in this paper offers is designed to facilitate Internet access to application software. It emulates a real computing laboratory environment that promotes group learning and project management. The laboratory resources are situated at the university and are centrally controlled. Users of the virtual programming laboratory include students, tutors...
Electrochemical time-of-flight was used to measure the diffusion coefficients of 2,2,6,6-tetramethylpiperidine 1-oxyl derivatives, C n TPA, (3 to 7 CH 2 groups), in tropocollagen I solution, as a function of the chain length and the cross-linking with glutaraldehyde. The values of the diffusion coefficient of C n TPA in pure aqueous electrolyte follow the Stokes–Einstein law,...
Electrochemical Time-of-Flight (ETOF) method was used for the first time to measure the diffusion coefficient of 4-hydroxy-TEMPO, a molecular probe in collagen I matrix solution as a function of its concentration and the extent of crosslinking with glutaraldehyde (GA). The values of the diffusion coefficient were correlated with Circular Dichroism (CD) and viscosity data to assess the changes of the...
