In this work, we incorporated small amounts of synthesized GO and rGO in AC electrodes via a simple mixing procedure to explore their effects. In addition to materials characterizations, symmetric supercapacitors were made from these electrodes and tested across current densities ranging from 0.1–10 A g−1 and across 10,000 additional charge-discharge cycles at 2 A g−1. Performance measurements indicate that GO and rGO enhance the rate resistance and capacity, respectively, of AC electrodes, but these effects are modest and do not prevent increases in internal resistance over the course of 10,000 cycles. The overall ineffectuality of GO and rGO is reasoned to be due to their isolation and infrequ...

The increased concern for the environment has caused a broad shift from traditional marketing to green marketing. This phenomenon has been adopted by firms to gain profit and protect the environment. This study aims at determining the impact of green marketing on buyers' behavior. It discusses the level of green marketing among consumers, the attitude and perceptions consumers have of green marketing as well as the motivation to purchase green products. Questionnaire results on 77 people within the frontiers of the University of Cape coast were evaluated. On the face of the findings, an inference was made that consumers, specifically, educated consumers are aware of Green marketing. Likewise, consumers attitudes, motivation, and perceptions of green marketing influence on their buying behavior were found to be favorable. The study, however, found that patronage of green products amongst respondent were low as compared to the level of awareness. From the study, it was concluded that green marketing has a significant impact on the buyer's behavior. In view of this, it is recommended that firms grasp the opportunities that green marketing practices present and more importantly, firms should adopt rigorous green marketing strategies to magnify consumers' perception of green marketing. Besides, firms can invigorate a green lifestyle through the steep effort of green marketing strategies revolving around price, place, promotion, product and process development and improvement.
