“…The potential difference between two electrodes is given by ,,, normalΔ normalV = s ( x ) · [ ε 1 d 1 + ε 2 d 2 ] + x ( t ) [ σ false( x false) − σ 0 ε 0 ] No charge transfer occurs under open circuit conditions, i.e., σ( x ) = 0. The open-circuit voltage ( V oc ) is presented by V normalO normalC = σ 0 . x ( t ) ε 0 Under short circuit conditions, Δ V = 0.…”

“…Owing to the high electroactive phase presence, more dipoles are formed because of the rapid transfer of more electrons onto the surface of the negative surface (PVI 5) from the positive surface (nylon) of the device. 7,57,58 To further evaluate the output performance of the TECS 5 device, the output response was recorded under different amplitudes of separation between two dielectric layers (2−10 mm) at frequency 5 Hz and is presented in Figure 7e,f. This result shows that with increasing separation, the output voltage and current have increased gradually.…”

“…Higher CsPbI 3 loading (i.e., 6 and 7 wt %) gradually reduces the output performance of the device, which may be a result of the rapidly rising dissipation factor value ensuing in the low dielectric nature of those hybrid films. , The superior output performance of the TECS 5 device is also attributed to the high electroactive phase fraction of PVI 5. Owing to the high electroactive phase presence, more dipoles are formed because of the rapid transfer of more electrons onto the surface of the negative surface (PVI 5) from the positive surface (nylon) of the device. ,, To further evaluate the output performance of the TECS 5 device, the output response was recorded under different amplitudes of separation between two dielectric layers (2–10 mm) at frequency 5 Hz and is presented in Figure e,f.

Recent Advances in MXenes Based Composites as Photocatalysts: Synthesis, Properties and Photocatalytic Removal of Organic Contaminants from Wastewater

“…Initially, MXene materials were investigated as promising alternatives for electrochemical energy storage in batteries and supercapacitors due to their high electrical conductivity, structural stability, and hydrophilicity. [61,[65][66][67][68] The 2D layered titanium carbide powder (Ti 3 C 2 T x ) was the first MXene material that was studied extensively for energy storage and transfer in devices such as Li/Na ion batteries and supercapacitors. [69] Since then, MXene materials have found applications in various fields, including environmental remediation.…”
