Three-dimensional hierarchical ZnO films with lotus-leaf-like micro/nano structures were successfully fabricated via a biomimetic route combining sol-gel technique, soft lithography and hydrothermal treatments. PDMS mold replicated from a fresh lotus leaf was used to imprint microscale pillar structures directly into a ZnO sol film. Hierarchical ZnO micro/nano structures were subsequently fabricated by a 10 low-temperature hydrothermal growth of secondary ZnO nanorod arrays on the micro-structured ZnO film. The morphology and size of ZnO hierarchical micro/nano structures can be easily controlled by adjusting the hydrothermal reaction time. Wettability of hierarchical ZnO thin films was found to convert from superhydrophilicity to hydrophobicity after a low-surface-energy fluoroalkylsilane modification. Improved wetting properties from hydrophobic to superhydrophobic can be tuned by increasing the 15 growth of ZnO nanorods structures. 85 Notes and references

Fabricating ZnO nanorod arrays with precisely controlled morphology, alignment, and density is highly desirable but rather challenging. On the other hand, understanding the parameters that affect their final morphology and the growth mechanisms is significant to integrate such patterned ZnO nanorod arrays in various applications. Therefore, ZnO nanorod arrays with different density and morphology were fabricated by electron beam lithography (EBL) combined with the hydrothermal methods in this work. The influences of prepatterned geometry and the growth parameters such as seed layer, the precursor concentration, and the growth time on their final morphology were investigated. Under the coactions of EBL and the subsequent hydrothermal growth, ZnO nanorod arrays with precisely controlled density, position and morphology were achieved. The growth mechanism was also discussed in detail for the ZnO nanorod arrays which confined by the aperture with different size.

The study in this article provided principals with different types of information about professional school counseling and examined the impact on their perceptions. Results demonstrated that information about the ASCA National Model® influenced principals’ perceptions of the amount of time counselors should allocate to delivery of the guidance curriculum, system support, and responsive services, as well as ratings of the importance of performing inappropriate tasks in meeting the education mission of the school.

Using the High School Longitudinal Study of 2009, we investigated school counselors’ caseloads, how they spent their time, and the impact of those factors on schools’ academic outcomes. Results showed that approximately 85% of the school counselors had a caseload of 455 or fewer students, with roughly one quarter reporting caseloads equal to or less than 250, and that school counselors spent more of their time on college, scheduling, and personal/social/academic/career development. We also found that how school counselors spent their time was predictive of ninth-grade retention rates, the percentage of students who enrolled in Advanced Placement (AP) courses, and the percentage of students who enrolled in 4-year universities. We provide discussion and implications for school counselors.

The profession of school counselling in China is in relative infancy. A qualitative analysis of in-person interviews with fourteen high school counsellors sought to identify salient factors currently facing the profession in two urban Chinese schools. The counsellors described the development and practice of school counselling as well as their own view of the profession. Results are discussed in the context of relevant literature in China and compared to the current and historical development of school counselling around the world.
