Karen goes to the gym 3 days a week and focuses on cardio activities such as the elliptical trainer and recumbent bikes. With her sedentary job, she is always looking for ways to increase her activity through the day. She ensures she gets up every hour and tries to do 10 minutes of sta...
In the presence of CO2 gas together with H2O, the photogenerated electrons may participate in reducing CO2 to CO, CH4 or other forms of carbohydrates, competing with the H2 production process due to the fact that the redox potentials for CO2 reduction are close to that of H2/H2O [9]. On...
