A Novel Blue to Transparent Polymer for Electrochromic Supercapacitor Electrodes

Electrochromic supercapacitors may alert the user on the remaining capacity of the devices. The color change indicating the remaining capacity can be simply and rapidly recognized by the human eye or by optical instruments. A rapid indication of charged state may extend device service life and prevent overcharging, which would otherwise result in electrode aging and decomposition. In this study, a blue to the transmissive electrochromic polymer, poly(4,7-bis(2,3-dihydrothieno[3,4-B][1,4]dioxin-5-YI)-2-(2-octyldodecyl)-2H-benzo[D][1,2,3]triazole) (P1C), was used in nanocomposite form with transparent silver nanowire (Ag NW) network current collectors for the fabrication of electrochromic supercapacitor electrodes. Highly conductive and transparent Ag NW networks have an important role in the realization of electrochromic supercapacitors using P1C. Fabricated Ag NW/P1C nanocomposite electrodes had a specific capacitance of 65.0Fg(-1) at a current density of 0.1Ag(-1). Nanocomposite electrode showed excellent stability (capacity retention of>98%) after 11000cycles associated with a resistance decrease associated with charge transfer

The importance of trust for partnership and collaboration in volatile economic conditions

WOS: 000415645900012Volatile economic conditions are painful for most firms. Firms struggle to survive when market demand is sluggish, uncertainties are high, and credit conditions are tight. Therefore, maintaining and strengthening partnerships, retaining existing customers or finding new ones through innovation, and finding external finance are extremely vital to keep firms alive during volatile economic conditions. In this chapter we argue that trust plays a key role in protecting strong relationships with partners, customers, suppliers, and other actors or when developing new relationships. Trust might help to protect partnerships and establish collaborative relationships by mitigating asymmetric information and free-rider problems, allowing for more open and honest information sharing and restraining opportunistic behaviour
