A Plant-Transpiration-Process-Inspired Strategy for Highly Efficient Solar Evaporation

Abstract: The conversion of solar energy into heat for solar steam generation is significant for energy saving and clean water supply Recent advances in the design and application of photothermal-based water-evaporation systems have attracted intense research interest However, it is imperative to develop a low-cost and scalable photothermal system with further improved energy conversion efficiency to meet the demand for real-world applications Inspired by the natural transpiration process of plants, a wood-polydopamine-based photothermal material is developed for solar-steam generation Both the wood and polydopamine (PDA) derived from natural products are cost-effective, biodegradable, and environmentally friendly The wood–PDA system evaporates thin water film right above the bulk water surface, leading to extremely high efficiencies Solar steam can be generated only 5 s after light irradiation The solar-steam generation efficiency reaches 87% under 10 sun More significantly, an explosive evaporation which bypasses the phase change from liquid to gas is observed on the wood surface under irradiation of more-intense light This yields a solar-steam generation efficiency (calculated by the classic equation) beyond 100% (eg, 135% under 35 sun) It is envisioned that this strategy can be readily applied in practical solar-evaporation applications due to its simplicity, low cost, and high efficiency

Using Learning Analytics to Scale the Provision of Personalised Feedback.

Abstract: There is little debate regarding the importance of student feedback for improving the learning process. However, there remain significant workload barriers for instructors that impede their capacity to provide timely and meaningful feedback. The increasing role technology is playing in the education space may provide novel solutions to this impediment. As students interact with the various learning technologies in their course of study, they create digital traces that can be captured and analysed. These digital traces form the new kind of data that are frequently used in learning analytics to develop actionable recommendations that can support student learning. This paper explores the use of such analytics to address the challenges impeding the capacity of instructors to provide personalised feedback at scale. The case study reported in the paper showed how the approach was associated with a positive impact on student perception of feedback quality and on academic achievement. The study was conducted with first year undergraduate engineering students enrolled in a computer systems course with a blended learning design across three consecutive years (N2013 = 290, N2014 = 316 and N2015 = 415).

Initiating and utilizing shared leadership in teams: The role of leader humility, team proactive personality, and team performance capability.

Abstract: The present study was designed to produce novel theoretical insight regarding how leader humility and team member characteristics foster the conditions that promote shared leadership and when shared leadership relates to team effectiveness. Drawing on social information processing theory and adaptive leadership theory, we propose that leader humility facilitates shared leadership by promoting leadership-claiming and leadership-granting interactions among team members. We also apply dominance complementary theory to propose that team proactive personality strengthens the impact of leader humility on shared leadership. Finally, we predict that shared leadership will be most strongly related to team performance when team members have high levels of task-related competence. Using a sample composed of 62 Taiwanese professional work teams, we find support for our proposed hypothesized model. The theoretical and practical implications of these results for team leadership, humility, team composition, and shared leadership are discussed. (PsycINFO Database Record
