In contrast, poor surface modification was resulted when the functionalization was conducted at pH > 9, in which iron oxide and PSS repulse each other upon having similar surface charge.
The analysis of data and reporting of results should then lead to the recognition of good performance, improvement of poor performance and modification of the performance evaluation system if required.
However, fullerene-embedded OSCs encounter great challenges of low flexibility for structural modifications, poor absorption and blend morphological stability.
This can be useful in modifications poor countries can make to the model to get similar results in lower price or with more flexible/available choices.
Literature on the design of efficient nonfouling membranes by in-situ modification is poor, which can be explained by the difficulty to control membrane formation mechanisms when a third material is added to the casting solution, or by the lack of stability of matrix polymers with surface-modifiers.
In the case of carbon as support, even though Pd/C exhibits good conversion in the hydrodehalogenation of CCl2F2, the selectivity towards HFC-32 is poor, and hence the modification of carbon support is aimed to enhance the selectivity towards HFC-32.
About one third of hypertensive patients with inappropriate clinical action remained in poor control without therapy modification.
Apart from inadequate training in counselling skills, they also report numerous other barriers such as language, lack of time, poor knowledge of lifestyle modification and poor continuity of care [ 10, 11].
It is well known that poor adherence to lifestyle modification programmes, particularly those involving exercise, often leads to the failure of the programme in reaching its intended goals.
Struyf et al. in their study applied 1 kg load to the healthy musicians at 90 degrees of abduction and showed poor reliability with this modification, which is in contrast with our results [ 7].
