    Practically, an ideal catalyst for Formic acid-decomposition is one that best suits the reaction and significantly lowers its activation energy and improves the reaction rate under favourable conditions. Several catalysts for Formic Acid (FA)-decomposition reactions were examined. Based on the volcano curve and the potential of copper to give high hydrogen yields, emphasis was placed on a Cu-catalysed reaction as potential system for sustainable hydrogen production. Some recent advances in hydrogen production from formic acid were discussed and an effective system for FA-decomposition for hydrogen production was proposed. Since helium can be stored in weather balloons and weighs almost the same as hydrogen, a hydrogen buffer made from polyester fabric and coated with polyurethane or a hydrogen cylinder/tube was proposed for storing hydrogen for use as transportfuel. Also, due to the nature of the mechanisms/pathways describing FA-conversion reactions at the sites or surfaces of the copper-nanocatalysts, it is evident that the Cu(211) coordination site possesses the highest activation energy relative to those of Cu(100) and Cu(111), hence, the reason for the noticeable high or low hydrogen yields. Thus, the potential of Cu giving high hydrogen yields from FA spans from the reactions of FA at the Cu(111) and Cu(100) sites

    AIM: Surgeons make up a unique group that is at risk for developing work-related musculoskeletal symptoms. The purpose of this study was to evaluate the effect of Kinesiotape technique on pain and functional performance in surgeons who have musculoskeletal system pain after performing surgery. MATERIAL and METHODS: 32 surgeons between the ages of 27 and 44 yrs working in a university hospital were included. The Visual Analog Scale (VAS) was used to evaluate the surgeons' neck and low back pain and the Oswestry Low Back and Neck Disability Indexes were used to determine the impact of pain on daily living activities. First, surgeons were evaluated without Kinesiotape application, then evaluated again on the first day and fourth day of Kinesiotape application. RESULTS: The results showed that surgeons had a significant reduction in neck and low back pain (p<0.05). There were improvements in both Oswestry Low Back Disability Index and Neck Disability Index scores when compared with their initial status (p<0.05). After Kinesiotape application, neck and low back range of motions' scores showed an increase (p<0.05). CONCLUSION: Findings demonstrated that Kinesio taping would be an effective method for reducing neck and low back pain and improving functional performance.WoSScopu
