We present a facile and straightforward method to synthesize uniform poly(vinyl amine) hydrogel shells with excellent loading capability for active materials and controllable responsiveness to applied stimuli, providing tunable releasing properties.
We investigate theoretically the ternary copper chalcogenides with the general formula Cu2MMS4. This family of compounds can crystallize in two different non-centrosymmetric structures, I 4̄2m or Pnm21. We show that all the reported members of Cu2MMS4 having the Pnm21 symmetry exhibit a large spontaneous polarization. This result suggests that several of these materials are likely to be multifer...
Superionic materials are multi-component solids with simultaneous characteristics of both a solid and a liquid. Above a critical temperature associated with a structural phase transition, they exhibit liquid-like ionic conductivities and dynamic disorder within a rigid crystalline structure. Broad applications as electrochemical storage materials and resistive switching devices follow from this...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
