Thermodynamic and kinetic assessments of strontium-doped lanthanum manganite perovskites for two-step thermochemical water splitting
Solar-driven thermochemical water splitting using non-stoichiometric oxides has emerged as an attractive technology for solar fuel production. The most widely considered oxide for this purpose is ceria, but the extreme temperatures required to achieve suitable levels of reduction introduce challenges in reactor design and operation, leading to efficiency penalties. Here, we provide a quantitati...

متن کاملOnline formative assessments: exploring their educational value
Introduction: Online formative assessments (OFA’s) have beenincreasingly recognised in medical education as resources thatpromote self-directed learning. Formative assessments are usedto support the self-directed learning of students. Online formativeassessments have been identified to be less time consuming withautomated feedback. This pilot study aimed to determine whetherparticipation and pe...
متن کاملAlternative Assessments and EFL Learner Autonomy
Alternative assessments have evolved from an epistemological change in education. They see assessment and instruction as two sides on the same coin which go hand in hand. The traditional roles of both teachers and learners are, consequently, modified which is essential for better language development. In this line, the present study aimed at comparing the effects of portfolio and journal writin...
