No full textProduction of V-Doped P2-type Na<sub>0.67</sub>Mn<sub>0.5</sub>Fe<sub>0.43</sub>Al<sub>0.07</sub>O<sub>2</sub> Cathodes and Investigation of Na-Ion Full Cells Performance
No full textThe Na0.67Mn0.5Fe0.43Al0.07O2(x = 0-0.1) samples are successfully produced and their structural properties are investigated by common techniques. The highest surface area is found as 4.94 m(2) g(-1) for x = 0.04 V by the Brunauer-Elmet-Teller analysis. According to X-ray photoelectron spectroscopy of x = 0.04 V-doped sample,V4+, and V5+ ions are formed in the structure. The main phase is observed as P63/mmc symmetry with an impurity phase of V6O13 for x >= 0.06 . According to the CV analysis, while the redox voltage decreases for the Mn3+/Mn4+ , the intensity of the peaks of Fe2+/Fe3+ redox reaction decreases. While the best capacity value of the half cells at C/3-rate is obtained as 171 mAh g(-1) for x = 0.04, the lowest capacity fade is found for x = 0.08 . It is mentioned the V6O13 may contribute to the electrochemical process . The galvanostatic tests are investigated for the voltage windows of 3.5-1.5, 4-1.5, 4-2.5, 4-2, and 4-2.5 V and it is seen that the battery cells for 3.5-1.5 V have the best capacity fade (6%) among the others. The Na0.67Mn0.5Fe0.43Al0.07O2/ hard carbon is used for the full cells with presodiated anode and the first capacity value of the full cell is obtained as 80.2 mAh g(-1) for C/2-rate

Exercise sensitivity, physical activity, and kinesiophobia in patients with chronic coronary syndrome: a cross-sectional study
No full textIntroduction: Cardiac risk factors and diseases exacerbate anxiety and may cause exercise sensitivity by increasing awareness of physical conditions. However, the extent to which exercise sensitivity influences the level of physical activity and kinesiophobia in CVD patients is unclear. Aim: The current study aimed to determine exercise sensitivity and its associated kinesiophobia and physical activity levels in patients with chronic coronary syndrome (CCS). Material and methods: This cross-sectional study involved 43 patients diagnosed with CCS and 45 age- and gender-matched healthy individuals. Exercise sensitivity (questionnaire created by researchers), physical activity levels (short form Physical Activity Questionnaire, IPAQ), and kinesiophobia (Tampa Kinesiophobia Scale Heart, TSK-H) were evaluated. Results: The exercise sensitivity score (ESS, 37.40 ±7.38 and 33.65 ±5.83, p = 0.010) was higher in the CSS group. During exercise, feeling pain, depletion of energy fatigue, chest pain, chest tightness, dizziness, palpitations, dyspnoea, and fainting frightened the patients (p < 0.05). The TSK-H score was higher, and the difference was significant in CCS patients compared the healthy controls (p = 0.007). Tye physical activity level was lower in patients than in healthy controls (p < 0.001), and 58.1% of CCS patients were inactive. ESS was significantly associated with IPAQ score (r = –0.360; p = 0.018) and TKS-H score (r = 0.529; p < 0.001) in CCS patients. According to linear regression analyses, exercise sensitivity explains 25% of kinesiophobia and physical activity. Conclusions: Patients with CCS exhibit fear and sensitivity towards exercise, and these fears contribute to high levels of kinesiophobia and low physical activity levels. Future studies should be designed based on exercise sensitivity to increase participation in exercise-based programs
